Including providing a unified policy framework to control network behavior, or providing policy rules to control layer network functions, and responsible for obtaining user subscription information related to policy decisions. It is used to manage network behavior, provide policies and rules for the control plane, and generally make policy decisions based on contract information.

The RAN may be a network composed of multiple RAN devices to implement functions of the wireless physical layer, resource scheduling and wireless resource management, wireless access control, and mobility management functions. The RAN equipment is connected to the UPF entity through the user plane interface N3, and is used to transmit the data of the terminal equipment. The RAN device establishes a control plane signaling connection with the AMF entity through the control plane interface N2 to implement functions such as radio access bearer control. Wherein, FIG. 1 of the present application shows the wireless access network equipment, that is, the RAN equipment, which can also be replaced with wired access network equipment. In FIG. 1, only the RAN equipment is used for exemplary illustration, and in the following description of this application , directly referred to as access network equipment, including RAN equipment and wired access network equipment. Specifically, the access network device may be a device with a central control function, such as a macro base station, a micro base station, a hotspot (pico), a home base station (femeto), a transmission point (TP), a relay (relay), a Access point (access point, AP), etc. If the access network device is a base station, the base station may be a base station (eNodeB, eNB) in long term evolution (LTE), a base station (gNodeB, gNB) in new radio (NR), and the like.

In the embodiments of the present application, when the AF entity performs data transmission with core network network elements or access network devices, for example, PCF entities, access network devices, data analysis entities, NWDAF entities, etc., the NEF entity may forward. Specifically, when the AF entity sends data to the core network element or access network equipment, etc., the NEF entity can perform security authentication on the data (the NEF authenticates the AF identifier carried in the message sent by the AF, confirming that the AF is operating Commercially trusted AF), identity conversion (messages sent by AF may carry external identifiers, such as the user identifier to be served or the operation identifier of the message, etc. NEF needs to convert these external identifiers into internal identifiers recognized by core network elements ) and other steps, so that the core network element or the access network device can safely and correctly receive the data sent by the AF entity.

The NWDAF entity is used to analyze and predict the data of core network elements.

The data analysis entity can be used to perform data analysis and prediction on the information of the base station.

Exemplarily, a specific application scenario is described by taking the access network device as a base station as an example. For example, in a V2X communication scenario, the UE performs SL communication through the PC5 interface, and the SL carries important services, such as safety services, and sensor sharing services for autonomous driving. And different from the Uu interface communication, the base station can directly obtain the network resource status of the UE within its coverage, such as channel quality, congestion and the like. In the PC5 interface communication between the UE and the UE, the base station cannot directly obtain the communication quality of the PC5 interface of the UE within its coverage, such as channel quality parameters and congestion situation information. Estimating the performance of the network according to the channel quality reported by the current UE can only determine the network condition of the current location of the UE. After the UE reports the SL network information, as the position of the UE moves, the SL network information at the location of the UE has changed. The base station cannot accurately allocate or adjust the SL network information for the UE according to the SL network information reported by the UE Internet resources. Therefore, the embodiments of the present application provide a data processing method, which can more accurately adjust network resources for UE to perform SL communication.

The data processing method provided by the present application will be described below based on the network architecture of FIG. 1 above.

201. The access network device acquires information of N grids within a preset range.

The preset range may be a range set based on a cell, a sector or a base station, or a range set based on a map. For example, the preset range is a road area in the map, or, when the access network device is one or more base stations, the preset range is one or more cells under the one or more base stations, or, When the access network device is one or more base stations, the preset range is all or part of sectors under the one or more base stations. Wherein, a cell under the base station may be divided into one or more sectors.

The N grids may be grids obtained by dividing the preset range, and N is a positive integer greater than or equal to 1. The division of the grid can take various granularities. For example, the granularity is divided into the coverage of the cell with the minimum coverage within the preset range, so that the coverage of each grid is smaller than the minimum coverage. For another example, the granularity is the coverage of the smallest sector of the base station within the preset range, so that the coverage of each grid is smaller than the coverage of the smallest sector.

Wherein, the information of the N grids may include: the identification and coverage information of each grid in the N grids. The coverage size of each grid in the N grids may be the same or different.

The coverage information of each grid may include: the length and width of each grid, or the length, width and altitude of each grid. The raster identifier can be used to uniquely identify a raster, for example, the raster name. It should be pointed out that there are many situations in the coverage of each grid in the N grids. For example, the size of the coverage of each grid may be a preset value, that is, the coverage of each grid The ranges are all the same size. The coverage size of each grid may also be different, or, the coverage size of some grids in the N grids may also be the same.

Typically, the coverage of each raster can be divided into smaller ranges. For example, the coverage size of each grid is smaller than the coverage size of the smallest cell under the base station, or the coverage size of each grid is smaller than the average coverage size of multiple cells under the base station, or, the The coverage size of each grid is smaller than the coverage size of the smallest sector under the base station, etc., so that when the network device analyzes network resources in the future, it can be based on a smaller granularity than the cell, or more than the minimum sector granularity. Small grid granularity is used for analysis to improve the accuracy of the analysis results of network resources.

For another example, the data analysis entity may divide the preset range to obtain N grids, and send the information of the N grids to the access network device, and the access network device receives the information of the N grids from the data analysis entity. .

For another example, the AF entity may divide the preset range to obtain N grids, and send the information of the N grids to the access network device, and the access network device receives the information of the N grids from the AF entity.

In a second manner, the access network device divides the preset range into grids to obtain information of N grids within the preset range.

In an example, the access network device acquires the information of the map, and the preset range may be a part of the area or the whole area in the map. The access network device may divide the preset range based on the information of the map, obtain N grids within the preset scope, and assign an identifier to each grid in the N grids, thereby obtaining N grids grid information.

The information of the map may include information of geographic locations within the preset range, for example, the map may include roads, mountains, buildings, and the like within the preset range. The map information may be stored on the access network device, or may be sent to the access network device by other network elements. For example, the map information may be stored by an application server (AS) or a UDR network element. sent to the access network equipment.

Wherein, the access network device divides the preset range based on the information of the map, which may be divided according to the preset size, for example, the length of each grid is 20 meters and the width is 15 meters.

It should be noted that, if the above-mentioned method 2 is adopted, the above-mentioned method may further include: the access network device sends the information of the N grids to other network elements, for example, the PCF entity, the NWDAF entity, the AF entity or the data analysis entity , without restriction.

Wherein, the road information may include the situation of the road where the UE is currently located, for example, the road information includes the traffic flow density, vehicle speed and the like within a certain range around the location of the UE on the current road. Wherein, the certain range may be on the road, with the position of the UE as the center, and the length of the range of 100 meters before and after the position of the UE. The road information may also include road condition information collected by sensors or cameras on the UE, for example, road images, temperature, humidity, visibility, and the like.

In an optional implementation manner, the first SL network information further includes time information, that is, the collection time of the first SL network information, so that the access network device determines the first SL network information according to the collection time of the first SL network information. Whether a SL network information is available, or the available weights. This time information may also be referred to as a time stamp hereinafter. For example, the access network device may acquire the collection time of the first SL network information according to the time stamp, so as to determine whether the first SL network information has expired according to the collection time. If the difference between the collection time of the first SL network information and the current time is greater than a preset time value, the first SL network information may be discarded.

It should be noted that the UE may periodically report the first SL network information, so that the access network device may acquire the SL network information of the UE in real time. Furthermore, the access network device may obtain information on the communication quality of the SL communication performed by the UE according to the first SL network information reported by the UE, so as to perform network resource adjustment or network resource allocation for the UE.

203. The access network device sends the identifier of the first grid and the second SL network information related to the first grid to the network device according to the first SL network information.

The first grid is the grid where the UE is located, that is, the UE is located in the first grid. The N grids include the first grid, in other words, the first grid is one or more of the N grids.

The second SL network information related to the first grid may refer to SL communication information related to the one or more grids. For example, the second SL network information may include: identifiers of UEs within the first grid, channel quality information within the coverage of the first grid, and V2X service information of one or more UEs within the coverage of the first grid Or road information within the coverage area of the first grid, etc. The channel quality information, V2X service information, and road information can all refer to the relevant description in step 202 .

Wherein, the first SL network information and the second SL network information may be the same or different.

Wherein, when the first SL network information is the same as the second SL network information, step 203 may include: using the first SL network information as the second SL network information, and sending the identification of the first grid and the first grid to the network device 2.

When the first SL network information is different from the second SL network information, step 203 may include: the access network device obtains the second SL network information according to the first SL network information, and sends the identifier of the first grid to the network device and the second SL network information.

Wherein, the access network device may obtain the second SL network information according to the first SL network information in two ways.

Manner 1: The access network device preprocesses the first SL network information to obtain the second SL network information.

Exemplarily, if the access network device receives a set of first SL network information, it may add, delete or modify part of data in the set of first SL network information to obtain second SL network information. If the access network device receives multiple sets of first SL network information, and the access network device receives multiple sets of first SL network information, if the information includes different frequency bands (or channels), different roads or different locations, etc. Different information included in the multiple sets of first SL network information is classified and combined (for example, the first SL network information of the same location and different frequency bands is classified and combined, or the first SL network information of different locations of the same frequency band is classified and combined, etc.). The access network device may also calculate the parameters included in the multiple first SL network information to obtain the second SL network information. For example, the parameters used to measure the channel quality of the same channel included in the multiple sets of first SL network information, such as block error rate (block error rate, BLER), signal to interference plus noise ratio (signal to interference plus noise ratio, SINR), received power, etc., perform a weighted or average operation to obtain the calculated parameters, and then obtain the second SL network information, where the second SL network information includes the calculated parameters. In this embodiment of the present application, the second SL network information can be obtained by preprocessing the first SL network information, thereby reducing the redundancy of the second SL network information sent by the access network device to the network device, and improving the subsequent network information. Efficiency with which the device performs network resource analysis based on the second SL network information.

Manner 2: The access network device sends the first SL network information to the data analysis entity, the data analysis entity preprocesses the first SL network information to obtain the second SL network information, and sends the second SL network information to the access network device.

In addition, in step 203, the access network device may determine that the UE is located in the first grid according to the location of the UE and the information of the N grids. The location of the UE may be reported by the UE, for example, reported through the first SL network information, or obtained by the access network device locating the UE, or the access network device may obtain it from other network elements, not be restricted.

In a specific implementation manner, the coverage of the first grid is smaller than the coverage of the cell currently accessed by the UE, that is, the granularity of the first grid is smaller than the granularity of the cell. The access network device sends the SL network information of the first grid, for example, the second SL network information to the network device, for the network device to obtain the network resource analysis result based on the first grid. Since the first grid has smaller granularity than cells, the accuracy of the network resource analysis result based on the first grid is higher, and the method shown in FIG. 2 can greatly improve the accuracy of the network resource analysis result.

In the method provided by the embodiment of the present application, the access network device may acquire information of N grids within a preset range, and receive the first SL network information from the UE. Then, according to the first SL network information, the access network device sends the identifier of the first grid and the second SL network information related to the first grid to the network device, which are used for the network device to analyze the network resources and obtain the network resource analysis. result. Since the access network device provides the SL network information based on the grid granularity, the network device can analyze the network resources based on the grid granularity, so that the access network device can more accurately adjust the grid coverage according to the network resources. The UE can use the network resources that adapt to the change of the communication quality of the SL communication to perform the SL communication, improve the efficiency of the UE’s SL communication, reduce the delay of the UE’s SL communication, and avoid the occurrence of channels when the UE performs the SL communication. congestion situation. In addition, the granularity of the foregoing grid may be smaller than the cell granularity, sector granularity, etc. Therefore, the access network device may adjust the network resources of the UE based on the grid granularity according to the network resource analysis result of the grid granularity, so as to improve the adjustment of the network resources of the UE. The accuracy of the UE can achieve more accurate adjustment of the UE's network resources.

In a possible implementation manner, after the foregoing step 203, the foregoing method further includes: the access network device sends a first request to the network device.

Wherein, the first request is used for requesting to obtain the network resource analysis result of at least one grid. Moreover, the first request may carry the information of the at least one grid. For example, the first request may carry information such as the identifier and coverage of the at least one grid.

Wherein, the network resource analysis result of the at least one grid is an analysis result of the network resource of the at least one grid. The at least one grid may be located within the coverage area of the access network device.

In a possible implementation manner, the above-mentioned first request further carries the second SL network information in the above-mentioned step 203 .

In another possible implementation manner, in the foregoing step 203, a specific manner for the access network device to send the second SL network information to the network device may be: the access network device sends a first request to the network device.

Wherein, the first request is used for requesting to obtain the network resource analysis result of at least one grid. In addition, the first request carries the information of the at least one grid and the second SL network information in the foregoing step 203 .

The network resource analysis result of the at least one grid may include: the QoS level supported by the SL communication in the at least one grid, the congestion level of the SL communication in the at least one grid, the SL communication in the at least one grid The QoS key performance indicator (key performance indicator, KPI) that the communication satisfies or adjustment indication information, etc.

Specifically, the QoS level may include a PC5 quality of service identifier (PC5 QoS identifier, PQI). The PQI may be composed of multiple QoS parameters, such as delay, packet loss rate, priority, and the like.

Wherein, the congestion degree of SL communication in the at least one grid can be used to characterize the congestion situation of SL communication in the at least one grid. The network device may determine the congestion level of the SL communication in the at least one grid according to the number of UEs performing the V2X service or the channel occupancy in the at least one grid. Further, the network device may also combine parameters related to channel quality, such as SINR, received power, BLER and other parameters, to determine the degree of congestion of the SL communication in the at least one grid.

The QoS KPI may include: delay or packet loss rate, etc. Specifically, the delay may include an average delay or a maximum delay supported by each grid in the at least one grid, and the like. The packet loss rate may include: a maximum packet loss rate or an average packet loss rate of data transmission within the coverage area of the at least one grid.

The adjustment indication information may be resource adjustment indication information, which is used to indicate that network resources used by UEs within the coverage of the at least one grid need to be adjusted when performing SL communication.

The first preset condition may be: the parameter value in the network resource analysis result is within the first preset range, or the network resource analysis result includes the above-mentioned resource adjustment indication information, which is not limited. For example, if the network resource analysis result carries the QoS level supported by the SL communication in at least one grid range, correspondingly, the first preset condition includes: the QoS level currently supported by the SL communication within the at least one grid coverage area is low The QoS level of the V2X service of the UE within the range of the at least one grid. For another example, the first preset condition includes: the above-mentioned resource adjustment indication information is carried in the network resource analysis result.

Wherein, when the access network device sends the SL radio bearer configuration to the UE within the coverage of the at least one grid, the SL radio bearer configuration may include information about the network resources available to the UE, for example, the frequency of the PC5 resources available to the UE information, time domain information, and interface information (for example, the type or identifier of the interface, etc.) that supports V2X service data transmission in the PC5 resources available to the UE. Further, the UE may select the available network resources according to the information of the network resources available to the UE carried in the SL radio bearer configuration. It can be understood that the access network device can send the SL radio bearer configuration to the UE within the coverage of the at least one grid to notify the UE which PC5 resources are available, and the UE can select the available PC5 resources according to the SL radio bearer configuration. SL Communications.

Wherein, in the case that the access network device allocates network resources to UEs within the at least one grid range according to the network resource analysis result, the access network device may use the control channel to provide the at least one grid The information of the network resources allocated by the UEs within the coverage area is sent to the UEs within the coverage area of the at least one grid. Specifically, the access network device may, according to at least one grid range carried in the network resource analysis result, support the QoS level of SL communication, the congestion level of SL communication, the QoS KPI satisfied by SL communication, etc., from the at least one grid Among the network resources within the coverage, network resources corresponding to the communication parameters of the UE's V2X service within the coverage of the at least one grid are determined, and network resources are allocated to the UE within the coverage of the at least one grid.

Specifically, the information of the network resources allocated to the UE within the coverage of the at least one grid may include: frequency band information, time domain information of the network resources allocated by the access network device to the UE, and interface information supporting the transmission of V2X service data (for example, the type or identity of the interface). Further, the UE updates the current network resource configuration of the UE according to the received network resource information from the access network device, and then the UE uses the network resources allocated by the access network device to perform SL communication.

For example, when the access network device determines that channel congestion occurs in a certain frequency band according to the network resource result, the access network device can avoid the frequency band where the channel congestion occurs when allocating network resources to the UE, thereby avoiding the occurrence of channel congestion in the UE. The SL communication is performed in the frequency band with channel congestion, which reduces the time delay of the UE performing the SL communication and improves the efficiency of the UE performing the SL communication.

For another example, if the above-mentioned resource adjustment indication information is carried in the network resource analysis result, the access network device allocates the UEs within the coverage of each grid according to the network resources of each grid in the at least one grid. The network resources used in SL communication, so that the network resources for UEs within the coverage of each grid to perform SL communication can be allocated by the access network device, so that the access network device can perform SL communication based on grid granularity. The network resources of the SL communication are scheduled to avoid channel congestion caused by the UE's self-selecting of network resources.

In another specific implementation manner, when the above-mentioned network device is an NWDAF entity, and the data analysis entity is a device deployed independently of the access network device, the above-mentioned step 201 or step 203 may also be performed by the data analysis entity, The workload of the access network equipment can be reduced.

Wherein, for the information of the N grids within the preset range, reference may be made to the relevant description in the foregoing step 201, and details are not repeated here.

Wherein, step 301 can be implemented in various ways, as described below.

Manner 1: The network device receives information of N grids from other network elements, and the other network elements may be PCF entities, access network devices, or AF entities, which are not limited.

For example, the PCF entity divides the preset range to obtain N grids, and sends the information of the N grids to the network device, and then the network device receives the information of the N grids from the PCF entity.

For another example, the access network device may divide the preset range to obtain N grids, and send the information of the N grids to the network device, and then the network device receives the information of the N grids from the data analysis entity.

For another example, the AF entity may divide the preset range to obtain N grids, and send the information of the N grids to the network device, and then the network device receives the information of the N grids from the AF entity.

Manner 2: When the network device is a data analysis entity, the network device divides the preset range into grids to obtain information about N grids within the preset range.

Specifically, the manner in which the data analysis entity divides the preset range into a grid may be similar to the second manner in the foregoing step 202, and the access network device therein may be replaced by the data analysis entity, which will not be repeated here.

It should be noted that, if step 301 can be implemented by the above-mentioned method 2, after step 301, the method may further include: the data analysis entity sends the information of the N grids to other network elements, for example, the access network Device, PCF entity, NWDAF entity or AF entity, without limitation.

It can also be understood that the access network device may send the information of the N grids, the identifier of the first grid, and the second SL network information to the network device through the same message. For example, the access network device may send a first message to the network device, where the first message carries the information of the N grids, the identifier of the first grid, and the second SL network information.

For details of the second SL network information, reference may be made to the relevant description in the foregoing step 203 .

Specifically, after obtaining the identifier of the first grid and the second SL network information, the network device may determine that the second SL network information is related to the first grid based on the identifier of the first grid. Then, the network device obtains at least one grid network resource analysis result based on the second SL network information and through a preset algorithm.

For example, when the preset algorithm is a neural network algorithm, the number of UEs within the coverage of the first grid included in the second SL network information, the V2X service information performed by the UEs within the coverage of the first grid, One or more items of channel quality information within the coverage area of the first grid or road information within the coverage area of the first grid are used as inputs to the neural network algorithm, and network resource analysis results of at least one grid are output.

For the network resource analysis result, reference may be made to the relevant description in the foregoing step 203 .

In the method provided by the embodiment of the present application, the network device receives information of N grids and second SL network information related to the first grid. Therefore, the access network device can send the second SL network information to the network device based on the grid granularity, and the network device can obtain the network resource analysis result of at least one grid based on the grid granularity. Therefore, the network resources of the UE within the coverage of the grid can be accurately adjusted based on the network resource analysis result of the grid granularity. Further, the UE can use the adjusted network resources to perform SL communication, thereby improving the efficiency of the UE performing SL communication. , reducing the delay of the UE performing SL communication. In addition, the granularity of the grid in the embodiment of the present application is relatively small, for example, the granularity of the grid may be smaller than the granularity of the cell, the granularity of the sector, etc. Therefore, the network device may obtain the grid-based second SL network information based on the grid-based second SL network information. Network resource analysis results with grid granularity, the obtained network resource analysis results are more accurate. Further, when adjusting the network resources of the UE, the communication parameters of the V2X service or the QoS parameters of the V2X service, etc. based on the network resource analysis results, it can be adjusted according to the More accurate network resource analysis results Adjust the UE's network resources, V2X service communication parameters or V2X service QoS parameters, improve the accuracy of adjusting UE's network resources, V2X service communication parameters or V2X service QoS parameters, and realize the more accurate adjustment of network resources, communication parameters of V2X services or QoS parameters of V2X services.

Then, based on the preprocessed SL network information, the information of the N grids, and the identifier of the first grid, analyze the network resources of at least one grid in the N grids, and obtain the network resource analysis result of the at least one grid .

Wherein, for the manner of preprocessing the second SL network information by the data analysis entity, reference may be made to the manner in which the access network device preprocesses the first SL network information in the foregoing step 203, which will not be repeated here.

In a possible implementation manner, after step 303, the above method further includes:

The network device sends the network resource analysis result of the at least one grid to other network elements, for example, the access network device, the PCF entity or the AF entity, etc., which is not limited.

After step 303, or if the network device receives the first request after step 303, after the network device receives the first request, the network device also sends the network resource analysis result to the access network device. Therefore, in this embodiment of the present application, the access network device may request the network device for the network resource analysis result of the at least one grid according to requirements, so that the access network device can, according to the network resource analysis result of the at least one grid, perform an The UEs within the coverage of the at least one grid perform network resource adjustment or allocation, and the like.

In addition, when the network resource analysis result satisfies the second preset condition, the PCF entity may also send a control policy to the UE within the coverage of the at least one grid, where the control policy is used to adjust the data used when the UE transmits the data of the V2X service interface. For example, the control policy can be used to assign the UE to use the PC5 interface to transmit V2X service data in the first frequency band, and to use the Uu interface to transmit V2X service data in the second frequency band. Alternatively, the UE can use the PC5 interface to transmit V2X data in the first time period. Service data, the Uu port can be used to transmit V2X service data and so on in the second time period.

Further, the UE can use the adjusted QoS parameters of the V2X service to perform the V2X service, thereby improving the efficiency of the V2X service and reducing the delay of the V2X service.

Based on the data processing methods provided in the above-mentioned FIGS. 2-5 , the data processing methods provided by the present application will be further described below.

601. The access network device performs map rasterization.

Wherein, the access network device divides the preset range into grids based on the information of the map, and obtains information of N grids within the preset range, where N is a positive integer greater than or equal to 1. Wherein, for the rasterization of the map in step 601, reference may be made to the relevant description in the second method in step 202 above.

Specifically, the access network device obtains the information of N grids after gridizing the map. For the information of the N grids, please refer to the relevant description in the above step 201 .

Wherein, each grid in the N grids has a corresponding identifier, and one grid can be in one-to-one correspondence with one identifier. The identifier of each grid may be assigned to each grid when the access network device divides the grid, or the access network device may assign an identifier to each grid after the grid is divided. Specifically, the identification of each grid may be assigned according to a preset rule. For example, an identifier can be assigned to each grid in the order of grid division, or an identifier can be assigned to each grid randomly, or an identifier can be assigned to each grid according to the order in which each grid is arranged, etc. .

The preset range may be the cell coverage under the access network device, or the sector coverage under the access network device, or the access network device or other network elements according to preset rules based on map planning A predetermined range, for example, the preset range may be a road area on the map.

The N grids may be obtained by dividing the preset range by the access network device according to the preset size. For example, the access network device may divide the road according to the preset length, width or height (altitude), etc., to obtain N grids. The coverage area of each of the N grids may be smaller than a preset area. For example, the coverage of each grid may be smaller than the coverage of one or more cells under the access network device, or the size of the coverage of each grid is smaller than the average coverage of cells under the access network device Wait.

It should be noted that the shape of each grid may be a rectangle, a circle, a polygon, etc., and the shape of each grid may be the same or different, and may be adjusted according to actual application scenarios.

In an example, the preset range is taken as an example of a road in the map for description. As shown in FIG. 7A , the access network device may perform grid processing based on the road information of the map information, and divide the road into multiple grids. The width of the road can be taken as the width of each grid, and the length of each grid can be determined according to the operator's setting. It can be understood that the access network device segments the roads on the map, each segment of the road is a grid, and the length of each segment of the road can be set by the operator. When the width of the grid is the width of the road, the value of this width may be different in different scenarios. For example, the lane width of an urban road is 3.5 meters, a diversion lane at an intersection is 2.3-2.5 meters per lane, a trunk road (including expressways) is 3.75 meters per lane, and the shoulder (emergency stop zone of the expressway) is 1.5-2.5 meters, etc. . Also, there may be scenarios such as elevated roads and tunnels. Therefore, in some specific application scenarios, the coverage information of each grid may also include altitude.

In an example, the above-mentioned preset range is a cell under one or more base stations as an example for description. As shown in Figure 7B. Wherein, a base station is taken as an example, and the base station includes one or more cells, and three cells are used for description here. The base station may divide the coverage of the three cells to obtain multiple grids. A cell may be divided into one or more grids, and the size of the coverage of each grid is not greater than the size of the coverage of the smallest cell under the base station.

In an example, the above-mentioned preset range is a sector under one or more base stations as an example for description. The base station may also divide a sector into one or more grids based on the coverage of the sectors within its coverage. As shown in Figure 7C. Wherein, one base station may include one or more sectors, and three sectors are used for description here. The base station can divide the coverage of the three sectors to obtain multiple grids. Wherein, a sector may be divided into one or more grids, and the size of the coverage of each grid is not greater than the size of the coverage of the smallest sector under the base station.

In a possible implementation manner, when the access network device is one or more base stations, after the access network device divides and obtains the information of N grids, it can associate each grid with one or more base stations one or more of the cells below are matched. Then save the information of the grid to the data of the corresponding cell. For example, the coverage area of cell A includes grid 1, grid 2, and grid 5, and the coverage area of cell B includes grid 3, grid 4, and grid 6. The identifier of 5 is stored in the data of cell A, and the identifiers of grid 3, grid 4 and grid 5 can be stored in the data of cell B, etc. In addition, other network elements, such as an AMF entity, NEF entity, etc., can also match the N grids with the aforementioned one or more cells, and the process is related to the access network device matching the N grids with the aforementioned one or more cells. The manner in which the cells are matched is similar and will not be repeated here.

In another possible specific application scenario, in 3GPP TS 36.331 (5.10.13.2), area division is performed based on a map to obtain one or more zones. Then you can associate PC5 resources with zones, for example, save PC5 resources to the relevant data of the corresponding zone, please refer to the relevant standards for specific steps. In this embodiment of the present application, an access network device, a PCF entity, or a network device may match the grid with the zone, and associate the grid with the zone. Specifically, the information of the zone where each grid is located in the above-mentioned N grids can be saved in the information of each grid, or the information of each grid can be saved to the location where each grid is located The information of the zone is medium.

Wherein, the size of the coverage area of the grid provided by the present application is smaller than the size of the average coverage area of the zone, or the size of the coverage area of the grid provided by the present application is smaller than the size of the minimum coverage area of the zone. It can be understood that the grid obtained based on the map division in the embodiment of the present application may be a subset of the zone. For example, as shown in Figure 8, a zone can be divided into multiple grids. Among them, each grid has a corresponding PC5 resource. Moreover, each zone has a corresponding zone identification number (identification, ID). The ID of each grid can be associated with a zone ID. For example, the ID of each raster can contain the zone ID of the corresponding zone. When the coverage of the zone needs to be adjusted subsequently, the coverage of the zone can be adjusted with the grid as the granularity. As shown in FIG. 9 , with respect to FIG. 8 , one or more grids in FIG. 9 can be divided from zone A into zone B. When adjusting the coverage of a zone, it is only necessary to adjust the identification of the grid in the zone, for example, adding or deleting the identification of the grid corresponding to the zone, etc., without the need to re-adjust the longitude and latitude or Adjust the length, etc. The complexity of adjusting the zone can be reduced.

In a specific implementation manner, after step 601, the above method further includes: the access network device sends the information of the N grids to other network elements, for example, a PCF entity, a data analysis entity, an NWDAF entity or an AF entity etc., without limitation.

Optionally, step 601 may be replaced with step 6011 .

6011. The PCF entity performs map rasterization.

The step of rasterizing the map in the above step 601 may also be performed by the PCF entity. The step of performing map rasterization by the PCF entity is similar to the step of performing map rasterization by the access network device in step 601, and the access network device in step 601 may be replaced by the PCF entity, which will not be repeated.

In a specific implementation manner, after step 6011, the above method further includes: the PCF entity sends the information of the N grids to other network elements, for example, access network equipment, NWDAF entity, data analysis entity or AF entities, etc., without limitation.

Optionally, step 601 may be replaced with step 6011 .

6012. The AF entity performs map rasterization.

The step of rasterizing the map in the above step 601 can also be performed by the AF entity. The step of performing map rasterization by the AF entity is similar to the step of performing map rasterization by the access network device in step 601, and the access network device in step 601 may be replaced by the AF entity, which will not be repeated.

In a specific implementation manner, after step 6012, the above method further includes: the AF entity sends the information of the N grids to other network elements, for example, access network equipment, NWDAF entity, data analysis entity or PCF entities, etc., without limitation.

602. The UE reports the first SL network information to the access network device.

For the first SL network information, reference may be made to the relevant description in the foregoing step 202 .

The UE may report the first SL network information to the access network device through radio resource control (radio resource control, RRC) signaling.

There are various ways for the UE to report the first SL network information, as described below.

Manner 1: The UE may periodically report the first SL network information to the access network device.

The period for reporting the first SL network information may be written into the configuration information delivered to the UE by the PCF entity, and the UE reads the reporting period from the configuration information, and then reports the first SL network information according to the reporting period. Or, in the signaling sent by the access network device to the UE, it carries an indication instructing the UE to periodically report the first SL network information to the access network device, and the reporting period. Report the first SL network information to the access network device automatically.

For example, when the UE initiates a V2X service request to the access network device or the PCF entity, or when the UE periodically performs configuration update or registration update, etc., the PCF entity can deliver configuration information to the UE through the AMF entity. The configuration information can carry the period for the UE to report the first SL network information.

For another example, when the access network device sends radio resource control (radio resource control, RRC) signaling to the UE, the RRC signaling carries an instruction instructing the UE to periodically report the first SL network information to the access network device, and reporting cycle.

Therefore, in this method, the UE can periodically report the first SL network information, for example, the UE reports the first SL network information to the access network device f1 times every minute, so that the access network device can periodically obtain the first SL network information. SL network information. Furthermore, the access network device may also periodically send the second SL network information to the network device, and periodically receive the network resource analysis result from the network device, so that the access network device periodically scans the grid coverage area. The adjustment or allocation of the network resources of the UE. Further, the UE can use the adjusted or allocated network resources to perform SL communication, thereby improving the efficiency of the UE performing the SL communication and reducing the time delay of the UE performing the SL communication.

Manner 2: The UE reports the first SL network information according to the trigger condition.

Wherein, the access network device carries information that triggers the trigger condition for the UE to report the first SL network information to the access network device in the signaling sent to the UE.

The triggering condition may include: CBR is lower than a preset threshold, or the current channel quality cannot meet the current communication requirements, for example, the delay of the UE performing the SL communication is higher than the first threshold, or the loss of the UE performing the SL communication The packet rate is higher than the second threshold, etc., which cannot meet the needs of V2X services.

Specifically, the access network device may carry the trigger condition information in the RRC signaling sent to the UE.

Therefore, in this manner, when the UE determines that the CBR is lower than the preset threshold, or when the UE monitors that the current channel quality cannot meet the current communication requirements, it can report the first SL network information to the access network device, so that the access network can The network access device can obtain the change of the communication quality when the UE performs the SL communication in time.

Manner 3: When the access network device needs to acquire the first SL network information, it directly delivers to the UE reporting indication information that instructs the UE to report the first SL network information.

Further, after receiving the reporting indication information from the access network device, the UE may report the first SL network information to the access network device.

Therefore, in the third mode, the access network device can notify the UE to report the first SL network information according to the requirements, which can reduce the amount of data sent by the UE and reduce the signaling overhead of the UE.

In addition, after step 602, the above method further includes: the first SL network information may carry the location information of the UE, and the access network determines that the UE is in the first grid according to the location information. For example, the first SL network information carries the longitude and latitude of the location of the UE, and the access network device may, according to the longitude and latitude of the location of the UE, and the longitude and latitude coordinates of each grid, or the first SL network The information carries the longitude and latitude of the location of the UE and is converted into plane coordinates, and is compared with the plane coordinates converted from the longitude and latitude of each grid above to determine that the UE is in the first grid, and the first grid is included in the grid. The above N grids.

603. The access network device performs data preprocessing.

Wherein, step 603 in this embodiment of the present application is an optional step.

After receiving the first SL network information sent by the UE, the access network device may preprocess the first SL network information to obtain the second SL network information.

The specific steps of the preprocessing and the second SL network information may refer to the relevant description in the foregoing step 203 .

In an example, if there are two UEs reporting the first SL network information of the SL communication to the access network device in the first frequency band, the first grid, and the first time period, the access network device may report the first SL network information of the SL communication to the two UEs. The first frequency band, the first grid, and the first SL network information reported in the first time period are preprocessed, for example, the data included in the first SL network information is processed by weighting, averaging, etc., so as to obtain the preprocessed SL network information . Therefore, in this embodiment of the present application, the data redundancy of the first SL network information can be reduced by preprocessing the first SL network information by the access network device, and the efficiency of data analysis by the network device can be improved.

In an example, if there are multiple UEs reporting their currently used or monitored CBRs in the same grid, the access network device performs weighted average or other quantization operations on the CBRs reported by multiple UEs to obtain each grid A CBR corresponding to the grid, thereby reducing the redundancy of the CBR of the same grid.

In a possible implementation manner, if there are multiple sets of first SL network information, each set of first SL network information in the multiple sets of first SL network information may carry different information of the corresponding UE, for example, Information about the location of each UE, information about the V2X service performed by each UE, etc., for different information in each set of first SL network information, the information may be directly included in the second SL network information without preprocessing That's it.

In an optional implementation manner, the access network device periodically preprocesses the first SL network information, and the period of preprocessing the first SL network information is generally smaller than that in the foregoing step 602 when the UE reports the first SL The cycle of network information. For example, the access network device may perform f2 preprocessing on the first SL network information every minute, where f2 is smaller than f1 in the foregoing step 602 .

In another implementation manner, when the data analysis entity is deployed independently of the access network device, step 603 may also be performed by the data analysis entity. After the access network device receives the first SL network information, the first SL The network information is sent to the data analysis entity. The process of preprocessing the first SL network information by the data analysis entity is similar to the step of preprocessing the first SL network information by the access network device, and details are not repeated here.

604. The access network device sends the identifier of the first grid and the second SL network information to the network device.

Wherein, step 604 in this embodiment of the present application is similar to step 203 above, and details are not repeated here.

In addition, when the data analysis entity performs step 603, the data analysis entity may also send the identifier of the first grid and the second SL network information to the NWDAF entity.

605. The access network device sends an SL network performance prediction request to the network device.

Wherein, the SL network performance prediction request sent by the access network device to the network device, that is, the first request described in the foregoing step 203, refer to the relevant description in the foregoing step 203 for details, which will not be repeated here.

In a possible implementation manner, the access network device may send the SL network performance prediction request, the identifier of the first grid, and the second SL network information through the same message.

Specifically, in step 605, it can be understood that, if the access network device needs to predict the SL network performance in some areas, it can compare the second SL network information and the first grid to the area where the SL network performance prediction needs to be performed. The identification of the grid is sent to the network device, so as to request the network device to obtain a network resource analysis result of at least one grid, where the at least one grid may be the first grid or the first grid and grids near the first grid. The network resource analysis result can be used by the access network device to adjust or allocate network resources used by the UE.

In a specific implementation manner, the access network device may periodically send an SL network performance prediction request to the network device, so as to request the network resource analysis result of at least one grid, so as to realize all the UEs in the at least one grid. Real-time regulation of used network resources. For example, the access network device may send the SL network performance prediction request to the network device f3 times per minute, where f3 is less than f2 in the foregoing step 603 . Moreover, when sending the SL network performance prediction request, the access network device carries the second SL network information in the current period, and for the second SL network information, please refer to the relevant description in the foregoing step 203 .

In another specific implementation manner, the access network device may send the SL network performance prediction request to the network device according to the trigger event. The trigger event may include: the UE requests the access network device to allocate network resources, or the value of the CBR reported by the UE is greater than the preset value, or the value of the road information vehicle density reported by the UE is greater than the preset vehicle density value, etc.

Specifically, the access network device can send the SL network performance prediction request, the identifier of the first grid, and the second SL network information through the same message. The second SL network information may be the first SL network information in the foregoing step 602, or may be the SL network information after preprocessing the first SL network information.

Exemplarily, two scenarios of the preprocessed SL network information and the unprocessed first SL network information are exemplarily described.

Scenario 1: The access network device sends the preprocessed SL network information to the network device.

Specifically, when the access network device sends the SL network performance prediction request, the identifier of the first grid, and the processed data of the first SL network information to the network device through the same message, see Table 1 for the specific content of the message.

Table 1

Wherein, the content requested by the access network device to the network device, which can be understood as the SL network performance prediction request, may include the coverage of at least one grid (including the grids near the first grid in Table 1) The QoS level supported by the SL communication, or the congestion level of the SL communication under the coverage of at least one grid, etc.

The information of the first grid and the information of the grids near the first grid in Table 1 may include the identifier of the first grid and the information of the second SL network. The grids near the first grid can be understood as grids adjacent to the first grid.

The information of the first grid may include a timestamp, an ID of the first grid, a frequency band in which the UE performs SL communication, channel quality reference information and CBR information (preprocessed data), and the like. Optionally, the information of the first grid further includes the number of UEs under the first grid, the UE IDs of the UEs within the coverage of the first grid, the movement track of the UEs within the coverage of the first grid, the first grid The V2X service information of the UE within the grid coverage (for example, the ongoing V2X service of the UE, the channel occupancy of the V2X service or the priority of the data packet of the V2X service, etc., refer to the relevant description in the above step 202), the UE perceives One or more items of road information (for example, local traffic flow density, vehicle speed, temperature, humidity, visibility, etc., see the relevant description in step 202 above) and other information. Wherein, the frequency band, channel quality reference information and CBR information for the UE to perform SL communication are preprocessed data, and for the preprocessing step, refer to the relevant description in the above step 203 . The information of the grids near the first grid is similar to the information of the first grid, and details are not repeated here.

In the first scenario, the access network device can send the preprocessed SL network information to the network device, which can reduce the redundancy of the sent data and improve the data sending efficiency. In addition, after the network device receives the preprocessed SL network information, the data volume of the preprocessed SL network information is less than that of the unpreprocessed SL network information. The network information obtains the network resource analysis result, which can reduce the workload of the network device and improve the work efficiency of the network device.

Scenario 2: The access network device sends unpreprocessed SL network information to the network device.

When the access network device sends the SL network performance prediction request, the identifier of the first grid and the unpreprocessed first SL network information to the network device through the same message, the specific content of the message may refer to Table 2.

Table 2

Among them, the content included in Table 2 is similar to the content included in Table 1, and the similar content will not be repeated. The difference is that the frequency bands, channel quality reference information, and CBR information for UEs within the coverage area of each grid in the first grid and the grids near the first grid carried in Table 2 for SL communication are unpredicted. processed data.

In the second scenario, if the access network device sends unpreprocessed SL network information to the network device, it may carry a large amount of first SL network information related to the first grid. The network device can more accurately obtain the usage of network resources under each grid based on the unpreprocessed SL network information. In practical applications, when the SL performance prediction request is sent, the more accurate the data carried in the SL network performance message, the more accurate the network resource analysis result obtained subsequently.

It should be noted that step 605 in the embodiment of the present application is an optional step, that is, step 605 may not be performed, or step 605 may be performed, which is not limited.

Optionally, the above step 605 can also be replaced with 6051.

6051. The AF entity sends an SL network performance prediction request to the network device.

The above-mentioned step 605 may also be performed by the AF entity.

The SL network performance prediction request sent by the AF entity to the network device is the second request in the foregoing step 502 . The SL network performance prediction request is used to request the network resource analysis result of at least one grid from the network device.

The AF entity may be unable to obtain the SL network information of the UE under at least one grid. Therefore, the SL network performance prediction request sent by the AF entity to the network device may not carry the second SL network information, and the access network The device sends the second SL network information to the network device.

Specifically, for the manner in which the AF entity sends the SL network performance prediction request to the network device, reference may be made to the manner in which the access network device sends the SL performance prediction request to the network device in the foregoing step 605 .

In a specific implementation manner, if the information of N grids is stored on the AF entity, the SL network performance prediction request sent by the AF entity to the network device may carry the information of at least one grid, for example, the at least one grid. identification, coverage, etc.

In another specific implementation manner, when the information of the N grids is not stored on the AF entity, the SL network performance prediction request sent by the AF entity to the network device may carry the location information corresponding to the network resource analysis result to be obtained. . For example, the SL network performance prediction request may carry: the longitude and latitude of the area for which the prediction is requested, or the information of single or multiple paths of the UE, or the coordinate information of the geometric area of the requested prediction range, etc. The network device may determine at least one grid corresponding to the network resource analysis result requested by the AF entity according to the location information of the UE carried in the SL network performance prediction request. Therefore, even if the AF entity does not include the information of the N grids, the location information of the requested area can be sent to the network device, so as to request the network device to obtain the network resource analysis result.

606. The network device performs data analysis.

Wherein, for step 606 in this embodiment of the present application, reference may be made to the foregoing step 303, and details are not repeated here.

There are various ways to trigger the network device to perform data analysis, as described below.

Manner 1: After step 605 or 6051, the network device may be triggered by the SL network performance prediction request to perform data analysis.

Wherein, in the first manner, the content included in the network resource analysis result may be different according to the content of the request carried in the SL network performance prediction request.

For example, if the SL network performance prediction request is used to request the network device to analyze the congestion situation of the SL communication, the network resource analysis result carries the congestion degree of the SL communication. If the SL network performance prediction request is used to request the network device to analyze the QoS level supported by the SL communication, the network resource analysis result may include the QoS level supported by the SL communication. If the SL network performance prediction request is used to request the network device to analyze some QoS parameter indicators in the SL communication, the network resource analysis result may include an indication of the QoS parameter indicators of the at least one grid that can meet the V2X service requirements, for example, The network resource analysis result may include indicators such as delay or packet loss rate, or the network resource analysis result may directly include an indication of whether the QoS indicator of the V2X service is satisfied, and the like.

In a possible scenario, when the SL network performance prediction request is sent by the AF entity, and the AF entity does not store the information of the above N grids, the SL network performance prediction request carries the information of the location that needs to be requested. , after receiving the SL network performance prediction request, the network device determines at least one grid corresponding to the location information according to the location information carried in the SL network performance prediction request. Then, the network resources of the at least one grid are analyzed to obtain a network resource analysis result.

Method 2: After step 604, data analysis can be performed.

In mode 2, if the access network device periodically sends the identifier of the first grid and the second SL network information related to the first grid to the network device, correspondingly, the network device may also periodically The identifier of the first grid and the second SL network information related to the first grid are used to analyze the network resources of the at least one grid to obtain the analysis result of the network resources of the at least one grid. The period for the network device to analyze the network resources of the at least one grid may be adjusted according to the period for the access network device to send the identifier of the first grid and the second SL network information related to the first grid.

In an example, the access network device may periodically send the SL network performance prediction request and the second SL network information within a preset time period to the network device. For example, the access network device may send the second SL network information within 5 minutes to the network device. So that the network device can obtain the network resource analysis result of the at least one grid based on the SL network performance prediction request and the second SL network information within the preset time period. The network resource analysis result may include information on the communication quality of the SL communication within the coverage area of the at least one grid in the future preset time period. Specifically, the network device may use the second SL network information collected in a preset time period as an input according to a preset algorithm, for example, a Kalman filter algorithm, a neural network algorithm, etc., and output the network resource analysis of the at least one grid As a result, the network resource analysis result may include information on the communication quality of the SL communication within the coverage area of the at least one grid in the future preset time period. The preset time period may be determined by the network device according to the prediction algorithm, or may be directly determined by the access network device.

Therefore, the access network device can send the SL network performance prediction request and the second SL network information within the preset time period to the network device, and request the network resource analysis result of the at least one grid, so that the access network device can obtain the result based on the prediction The network resource analysis result of the at least one grid in the future preset time period is adjusted, and the network resource of the UE is adjusted. It can be understood that the analysis or prediction of the communication quality of the SL communication can be realized based on the granularity of the grid through the Kalman filter algorithm or the neural network algorithm, etc., and then the communication quality of the SL communication can be analyzed or predicted accurately based on the results. Adjust the network resources of the UE to avoid channel congestion when the UE performs SL communication.

607. The network device sends the network resource analysis result to the PCF entity.

Wherein, after obtaining the network resource analysis result of the at least one grid, the network device may send the network resource analysis result of the at least one grid to the PCF entity.

Specifically, if the network device periodically analyzes the network resources of at least one grid, the network device may periodically send the network resource analysis result to the PCF entity.

It should be noted that step 607 in this embodiment of the present application is an optional step, that is, the network device may not send the network resource analysis result of at least one grid to the PCF entity.

608. The network device sends the network resource analysis result to the AF entity.

Wherein, after obtaining the network resource analysis result of the at least one grid, the network device may send the network resource analysis result of the at least one grid to the AF entity.

Specifically, there are many ways to trigger the network device to send the network resource analysis result to the AF entity, as described below.

Manner 1: The network device periodically sends the network resource analysis result to the AF entity. For example, if the network device periodically analyzes the network resources of at least one grid, the network device may periodically send the network resource analysis result to the AF entity.

Manner 2: The network device receives the SL network performance prediction request from the AF entity, and sends the network resource analysis result to the AF entity.

More specifically, the network device may forward the network resource analysis result to the AF entity through the NEF entity.

609. The network device sends the network resource analysis result to the access network device.

Wherein, after obtaining the network resource analysis result of the at least one grid, the network device may send the network resource analysis result of the at least one grid to the access network device.

Specifically, there are various manners for triggering the network device to send the network resource analysis result to the access network device, as described below.

Manner 1: The network device periodically sends the network resource analysis result to the access network device. For example, if the network device periodically analyzes the network resources of at least one grid, the network device periodically sends the network resource analysis result to the access network device.

Manner 2: The access network device sends an SL network performance prediction request to the network device, and the network device sends the network resource analysis result to the access network device.

610. The access network device sends the information of the network resource to the UE.

The information of the network resources is information of network resources available to the UE, or information of network resources allocated by the access network device to the UE. When the information of the network resource is the information of the network resource available to the UE, the information of the network resource may be sent to the UE by the access network device through the SL radio bearer configuration. When the network resource information is information of network resources allocated by the access network device to the UE, the access network device may directly send the network resource information to the UE.

Wherein, after the access network device receives the network resource analysis result of at least one grid from the network device, when the network resource analysis result satisfies the first preset condition, the access network device covers the at least one grid to the coverage area. The UE within the SL radio bearer configuration is sent; or, when the network resource analysis result satisfies the first preset condition, the access network device allocates network resources to the UE within the coverage of the at least one grid according to the network resource analysis result, and send the information of the allocated network resources to the UE.

For step 610, reference may be made to the relevant description of the above-mentioned step 203, and the step 610 will be described in more detail below with some specific scenarios.

For example, the network resource analysis result carries the QoS level supported by the SL communication in at least one grid range. Correspondingly, the first preset condition is that the QoS level carried in the network resource analysis result is lower than the preset QoS level. Therefore, when the network resource analysis result satisfies the first preset condition, the UE under the at least one grid needs to adjust the network resources used for the SL communication. The access network device may deliver the SL radio bearer to the UE under the at least one grid, and the SL radio bearer may include information about the network resources available to the UE, so that the UE can select the available network resources according to the SL radio bearer for SL. communication.

Wherein, the access network device may send the SL radio bearer configuration to the UE through RRC signaling or a system information block (system information block, SIB) message.

Generally, the access network device may send the SL radio bearer configuration to the UE within the coverage of the at least one grid, and notify the UE of the available PC5 resources. Specifically, the access network device may configure corresponding PC5 resources for the UE according to the PC5 authorization information or QoS parameters included in the communication parameters of the V2X service of each UE. For example, the higher the QoS level of the UE, the more PC5 resources are allocated to the UE; or, the more PC5 resources the UE is authorized to use, the more available PC5 resources are allocated to the UE.

For another example, if the network resource analysis result carries a value representing the degree of congestion in at least one grid, the first preset condition may be that the value indicating the degree of congestion in at least one grid exceeds a preset value. Then when the value exceeds the preset value, the access network device determines that the network resource analysis result satisfies the first preset condition, which can be understood as the congestion degree of the SL communication in at least one grid is relatively high, and the at least one grid needs to be congested. Adjust the network resources used by UEs within the grid coverage when performing V2X communication services. The access network device may allocate network resources for SL communication to the UE according to the network resource result, and deliver the information of the network resources allocated to the UE for SL communication to the UE. Further, the UE can update the network resource configuration according to the information of the network resources allocated by the access network device to the UE for SL communication, and use the network resources allocated by the access network device to the UE for SL communication to perform SL communication.

In an example, the frequency band for direct communication that the UE can use when performing the V2X service is the 5905-5925 MHz frequency band, which can also be understood as the working frequency band for the direct communication of the Internet of Vehicles in LTE-V2X applications. When the density of vehicle nodes on the road is too large, the channel congestion is easy to occur in the pass-through working frequency band of 20MHz bandwidth. When the access network device determines that the network resource analysis result satisfies the first preset condition, it may be understood that the communication quality of the current SL communication is poor, or a situation of channel congestion occurs. The access network device can send the SL radio bearer configuration to the UE to notify the UE of available PC5 resources, so that the UE can select PC5 resources for communication, or the access network device can allocate PC5 resources to the UE according to the network resource analysis result. Therefore, in this example, the UE can perform SL communication through the available PC5 resources or allocated PC5 resources, so as to improve the communication efficiency of the UE in the SL communication, and avoid channel congestion when the UE performs the SL communication.

Usually, the SL radio bearer configuration can also be understood as a pre-configured SL radio bearer, that is, the access network device predicts the possible poor communication quality or channel congestion of the SL communication according to the network resource analysis result obtained by the network device analysis. Therefore, through the pre-configured SL radio bearer, situations such as poor communication quality or channel congestion when the UE performs SL communication are avoided.

611. The PCF entity sends the communication parameters of the V2X service to the UE.

For step 611 in this embodiment of the present application, reference may be made to related descriptions after step 402 above, and details are not repeated here.

Wherein, when the network resource analysis result of at least one grid satisfies the second preset condition, the communication quality of the network resources in the at least one grid is poor, and there may be situations such as high delay and low transmission efficiency. Therefore, when the network resource analysis result satisfies the second preset condition, the PCF entity may send the communication parameters of the V2X service to one or more UEs within the coverage of the at least one grid according to the network resource analysis result, so as to realize the Adjustment of communication parameters of the V2X service of one or more UEs within the coverage of at least one grid.

For example, if the communication quality of the SL communication in at least one grid is poor and the QoS level supported by the SL communication is lowered, the PCF entity can reduce the V2X of the UE within the at least one grid by delivering the communication parameters of the V2X service The QoS level of the service is adapted to the change of the communication quality of the SL communication and avoids the channel congestion of the SL communication. Alternatively, the PCF entity adjusts the frequency band used by the UE to perform the V2X service by delivering the communication parameters of the V2X service to the UE, thereby avoiding the UE to communicate in the frequency band with poor channel quality, improving the communication quality of the SL communication performed by the UE, and reducing the communication quality of the UE. time delay.

For another example, if the communication quality of the channel in at least one grid is good and the QoS level supported by the SL communication is improved, the PCF entity can also correspondingly improve the QoS of the UEs within the range of the at least one grid by delivering the communication parameters of the V2X service. The QoS level of the V2X service is adapted to the communication quality of the SL communication and improves the communication quality of the UE in the SL communication. Alternatively, the PCF entity adjusts the frequency band used by the UE for the V2X service by delivering the communication parameters of the V2X service to the UE, so that the UE can communicate in the frequency band with better channel quality, and the communication quality of the SL communication by the UE can also be improved. The delay for the UE to perform SL communication.

612. The AF entity sends the QoS parameters of the V2X service to the UE.

For step 612 in this embodiment of the present application, reference may be made to the relevant description in the foregoing step 502, and details are not repeated here.

The V2X service referred to in this step is the service provided by the AF entity for the UE. For example, vehicles share sensor information services, vehicles periodically broadcast their own position, speed and other status information services, vehicles forward information services of other vehicles or roadside equipment, and so on.

Specifically, for the network resource analysis result, reference may be made to the relevant description of the foregoing step 203 .

Wherein, when the network resource analysis result satisfies the third preset condition, it can be understood that the communication quality of the network resources in the at least one grid is poor, and there may be situations such as high transmission delay and low transmission efficiency. Therefore, when the network resource analysis result satisfies the third preset condition, the AF entity may send the QoS parameter of the V2X service to one or more UEs within the coverage of the at least one grid according to the network resource analysis result, and the QoS parameter may be Used to adjust the QoS parameters of the UE's V2X service.

Therefore, the AF entity can adjust the QoS parameters of the UE's V2X service based on the grid granularity through the network resource analysis result based on the grid granularity, so as to more accurately adjust the QoS parameters of the UE's V2X service.

For example, if the communication quality of the SL communication in at least one grid is poor and the QoS level supported by the SL communication is lowered, the AF entity may deliver the QoS parameters of the V2X service to the UEs within the range of the at least one grid, reducing the at least one QoS parameter of the V2X service. The QoS level of the UE's V2X service within the grid range. Thus, the situation of channel congestion of SL communication is avoided.

For another example, if the communication quality of the channel in at least one grid is better, the QoS level supported by the SL communication is improved. Then, the AF entity can deliver the QoS parameters of the V2X service to the UEs within the at least one grid range, and improve the QoS level of the V2X services of the UEs within the at least one grid range. Therefore, the communication quality of the SL communication performed by the UE is improved, and the communication delay of the UE is reduced.

In an example, after the AF entity receives the network resource analysis result of at least one grid from the network device, if the network resource analysis result satisfies the third preset condition, it can be understood that the network resource is within the coverage of the at least one grid. The communication quality of the PC5 resource may be poor, or the channel may be congested. Therefore, the AF entity may send the QoS parameters of the V2X service to the UE that performs the V2X service within the coverage of the at least one grid. This enables the UE to configure the QoS parameters of the V2X service executed by the UE according to the QoS parameters of the V2X service. Therefore, the AF entity can adjust the QoS parameters of the UE's V2X service to make the QoS parameters of the UE's V2X service more suitable for the communication quality of the SL communication, improve the communication efficiency of the UE's SL communication, and reduce the communication delay of the UE.

In a specific scenario, in the above step 611, the QoS parameters included in the communication parameters of the V2X service sent by the PCF entity to the UE may be sent by one or more AF entities to the PCF entity, and then sent by the PCF entity to the UE. UE. Specifically, the AF entity may be an entity corresponding to the V2X service. The communication parameters of the V2X service sent by the PCF entity to the UE may include communication parameters of one or more V2X services of the UE, and the communication parameters of the one or more V2X services may include QoS parameters of the one or more V2X services. The QoS parameters of the one or more V2X services may be sent by the AF entity corresponding to the one or more V2X services to the PCF entity through the NEF entity, and then sent by the PCF entity to the UE.

Therefore, in the embodiment of the present application, one of the access network device, the PCF entity or the AF entity performs map rasterization, and notifies other network elements of the information of the N grids obtained by the rasterization. The UE within the coverage of the first grid may report the first SL network information to the access network device, and the access network device may send the identifier of the first grid and the second SL network information related to the first grid to the network device . The network device can obtain the network resource analysis result of at least one grid based on the information of the N grids, the identifier of the first grid and the second SL network information. and send the network resource analysis result to the access network device, the PCF entity and/or the AF entity, so that the access network device, the PCF entity and/or the AF entity can analyze the network resources of the UE, the communication parameters of the V2X service or the V2X entity The QoS parameters of the service and the like are adjusted to avoid the situation that the UE within the coverage of the at least one grid has poor communication quality or cannot communicate due to channel congestion of the SL communication.

The specific flow of the data processing method provided by the present application is described in detail above, and some specific application scenarios of the data processing method provided by the present application are described below.

Scenario 1: Map rasterization is performed by access network equipment.

Please refer to FIG. 10 , another schematic flowchart of the data processing method provided by the present application, which is specifically described as follows.

1001. The access network device performs map rasterization.

Wherein, in the embodiment of the present application, the access network device performs map rasterization to obtain information of N grids. For the information of the N grids, please refer to the relevant description in the above step 201 .

For example, after obtaining the map information, the access network device divides the road in the map into N segments based on the map information, that is, N grids are obtained. The length of each grid is the length of the N segments, and the width of each grid is the width of the road, or the width of each grid is greater than the width of the road.

When the access network device is a base station, there may be multiple base stations. Each base station can perform grid division on the roads within its coverage area, and by performing grid division on multiple base stations, information of N grids can be obtained.
