Terminal devices arranged to communicate via a wireless interface may also be referred to as wireless terminals or mobile terminals, examples of which include, but are not limited to, electronic devices such as telephones, PDAs, car-mounted devices, wearable devices, etc. Optionally, direct terminal (D2D) communication may be performed between the terminal devices.
The invention will be described in further detail with reference to the accompanying drawings and specific examples.
The embodiment of the invention provides an information processing method. Fig. 1 is a flow chart of an information processing method according to an embodiment of the present invention, and as shown in fig. 1, the method includes:
step 101, first network equipment detects resource demand;
Step 102, determining a specific frequency domain resource when the resource demand meets a first preset condition, and sending a first notification message comprising the specific frequency domain resource to a second network device, wherein the first notification message is used for notifying the second network device that the specific frequency domain resource is a frequency domain resource special for the first network device;
The frequency domain resources which can be scheduled by the first network equipment and the second network equipment are the same, and the specific frequency domain resources are part of the frequency domain resources.
The communication network of the embodiment can comprise a public network and a private network, wherein the public network can be accessed by any terminal equipment in a coverage area under a corresponding network mode, the private network can only be accessed by the private terminal equipment in the coverage area, and the private terminal equipment can use private service in the private network. It will be appreciated that the private network may allocate private radio resources for a particular area or a particular company, thereby enabling the private terminal device to use the private radio resources. It will be appreciated that the private network may have at least one first network device deployed therein, while the network adjacent to the private network may be a public network having at least one second network device deployed therein.
In this embodiment, the private network and the adjacent public network adopt the same-frequency networking mode, that is, the frequency domain resources that can be scheduled by the first network device deployed in the private network and the second network device deployed in the adjacent public network are the same.
Illustratively, the first network device and the second network device in this embodiment are both access network devices, e.g., base stations.
In this embodiment, when the first network device detects that the resource demand meets the first preset condition, that is, the resource demand is higher, it indicates that more users access the private network currently, and the resource demand of the private network is suddenly increased. Based on the above, the first network device determines a specific frequency domain resource, and sends a first notification message including the specific frequency domain resource to the second network device, so that the second network device knows that the specific frequency domain resource is a frequency domain resource dedicated to the first network device, and the second network device does not schedule the specific frequency domain resource.
The specific frequency domain resource is a private network resource fixedly used by a service channel of the private network under the condition that the resource demand meets a first preset condition. The specific frequency domain resource comprises at least one of a start frequency point, a cut-off frequency point and a bandwidth, and it is understood that the specific frequency domain resource can comprise the start frequency point and the cut-off frequency point, the start frequency point and the bandwidth, the cut-off frequency point and the bandwidth, and the start frequency point, the cut-off frequency point and the bandwidth.
In this embodiment, the first network device may send, to the second network device, a first notification message including the specific frequency domain resource through an interface with the second network device.
In some optional embodiments of the present invention, the first network device detecting a resource demand includes detecting, by the first network device, a number of users within a first preset time period, and the determining that the resource demand meets a first preset condition includes determining that the resource demand meets the first preset condition when detecting that the number of users within the first preset time period reaches a first preset threshold.
In this embodiment, when the number of users detected by the first network device in the first preset duration reaches the first preset threshold, it may indicate that more users access the private network currently, and the resource requirement of the private network increases suddenly. Optionally, the first network device may detect a number of radio resource control (RRC, radio Resource Control) connections within a first preset duration, and determine the number of RRC connections as the number of users. The first preset duration and the first preset threshold can be preset according to actual conditions. The first preset time period may be, for example, 1 second, and the first preset threshold may be, for example, 50.
In this embodiment, the first network device may determine the specific frequency domain resource by:
In a first manner, the determining the specific frequency domain resource includes the first network device obtaining the specific frequency domain resource configured by the network device.
The second mode includes that the specific frequency domain resource is determined, wherein the specific frequency domain resource comprises a first frequency domain resource configured by the first network equipment, load information of at least one second network equipment is obtained by the first network equipment, a second frequency domain resource is determined based on the load information, and the specific frequency domain resource is determined based on the first frequency domain resource and the second frequency domain resource.
The first mode is a semi-static resource sharing mode. Wherein the first network device obtains the specific frequency domain resource by means of network device configuration (network side configuration). It can be understood that at least one frequency domain resource of the start frequency point, the cut-off frequency point and the bandwidth is configured to the first network device by the network side.
The second mode is a dynamic resource sharing mode. The first network device obtains first frequency domain resources configured by the network device on one hand, and obtains load information of at least one second network device in a neighboring cell on the other hand, determines second frequency domain resources based on at least one load information, and determines the specific frequency domain resources from the first frequency domain resources and the second frequency domain resources. For example, the first network device may determine a minimum usage frequency domain resource bandwidth (i.e., a first frequency domain resource) based on a configuration of the network side, and the first network device may determine a maximum usage frequency domain resource bandwidth (i.e., a second frequency domain resource) based on load information of at least one second network device of the neighbor cell, and determine the specific frequency domain resource based on the first frequency domain resource and the second frequency domain resource.
In this embodiment, the first network device may send a request message to the second network device through an interface between the first network device and the second network device, where the request message is used to request current load information of the second network device, and correspondingly, the first network device may obtain load information fed back by the second network device through an interface between the first network device and the second network device. Illustratively, the load information characterizes a current uplink and downlink physical resource block (PRB, physical Resource Block) occupancy of the second network device.
In some alternative embodiments, the determining a second frequency domain resource based on at least one of the load information includes the first network device determining maximum load information of at least one of the load information, determining the second frequency domain resource based on the maximum load information, and the determining the specific frequency domain resource based on the first frequency domain resource and the second frequency domain resource includes determining a maximum of the first frequency domain resource and the second frequency domain resource as the specific frequency domain resource.
In this embodiment, if the load information is a current uplink and downlink PRB occupancy of the second network device, the first network device determines a maximum uplink and downlink PRB occupancy from at least one uplink and downlink PRB occupancy, and determines the second frequency domain resource based on the maximum uplink and downlink PRB occupancy. It can be appreciated that the uplink and downlink PRB occupancy is represented by a percentage.
For example, assuming that the maximum uplink and downlink PRB occupancy is NCellLoad max, the private network available resource bandwidth BW Private network in the specific frequency domain resource may be expressed as:
BW Private network ＝max(BW Private network min,100×(1-NCellLoadmax))
Wherein BW Private network min represents a minimum-use frequency domain resource bandwidth configured by the network device, the minimum-use frequency domain resource bandwidth being included in the first frequency domain resource. The frequency point start position and/or the cut-off position in the specific frequency domain resource can be configured by the network device.
In some optional embodiments of the present invention, the method further comprises the first network device sending a second notification message to the second network device when the first network device detects that the resource requirement meets a second preset condition, where the second notification message is used to notify the second network device to release the specific frequency domain resource.
In this embodiment, when the first network device detects that the resource requirement amount meets the second preset condition, that is, the resource requirement amount is lower, it indicates that the resource requirement of the current private network is suddenly reduced. Based on this, the first network device sends a second notification message to the second network device to cause the second network device to release the particular frequency domain resource, even though the second network device may schedule the particular frequency domain resource.
In some optional embodiments of the invention, the method further comprises the first network device sending a first reconfiguration message including the specific frequency domain resource to a terminal device, wherein the terminal device is any terminal device establishing connection with the first network device, and the first reconfiguration message is used for indicating that a traffic channel corresponds to the specific frequency domain resource.
In this embodiment, when determining that the resource demand meets the first preset condition, the first network device uses the specific frequency domain resource to schedule. In this scenario, the available resources of the traffic channel of the private cell correspond to the particular frequency domain resources, and the channel quality indication (CQI, channel Quality Indication) feedback for the traffic channel may take the following several ways:
In the first mode, the first network device sends a first reconfiguration message to the terminal device in the coverage area, wherein the first reconfiguration message comprises the specific frequency domain resource to inform the terminal device to reconfigure the frequency domain resource, and the terminal device is informed to reconfigure bandwidth or bandwidth part (BWP) in an exemplary manner, the CSI-RS and SRS frequency domain positions are updated along with the reconfiguration of the frequency domain resource, and the respective CQI feedback is used for scheduling the service channel.
In the second mode, the frequency domain resources of the terminal equipment are not reconfigured, and the CQI is fed back by adopting the frequency domain resources configured by the network side. The CQI feedback illustratively corresponds to the full band (full band representing the full bandwidth) of the network side configuration.
The third mode is that the frequency domain resource of the terminal equipment is not reconfigured, the terminal equipment adopts a sub-band CQI feedback mode configured by a network side, and the CQI feedback corresponds to the sub-band configured by the network side, wherein the sub-band is a part configured by the network side and corresponds to the full band, and it can be understood that the full band can be divided into a plurality of sub-bands in advance.
In some optional embodiments of the present invention, the first network device detecting that the resource demand meets a second preset condition includes determining that the resource demand meets a second preset condition when the first network device detects that the number of users in a second preset time period is less than a second preset threshold.
In this embodiment, when the number of users detected in the first preset duration is smaller than the second preset threshold, it may be indicated that fewer users access the private network currently, and the resource requirement of the private network drops suddenly. For example, the first network device may detect the number of RRC connections within a first preset time period, and determine the number of RRC connections as the number of users.
In some optional embodiments of the invention, the method further comprises if the first network device sends a second notification message to the second network device for notifying the second network device to release the specific frequency domain resource, the first network device sends a second reconfiguration message to the terminal device, where the second reconfiguration message is used to indicate that the traffic channel corresponds to the frequency domain resource.
In this embodiment, if the first network device sends the first reconfiguration message to the terminal device, and the first network device sends a second notification message for notifying the second network device to release the specific frequency domain resource to the second network device, the first network device also needs to send a second reconfiguration message to the terminal device, where the second reconfiguration message is used to notify the terminal device to restore the specific frequency domain resource to the original frequency domain resource.
Based on the foregoing embodiment, the embodiment of the present invention further provides an information processing method. Fig. 2 is a flow chart diagram of a method for processing information according to an embodiment of the invention, and as shown in fig. 2, the method includes:
Step 201, a second network device receives a first notification message sent by a first network device, wherein the first notification message comprises specific frequency domain resources, the frequency domain resources which can be scheduled by the first network device and the second network device are the same, and the specific frequency domain resources are part of the frequency domain resources;
Step 202, determining edge terminal equipment, wherein the edge terminal equipment is terminal equipment which establishes connection with the second network equipment and is positioned at the coverage edge of the second network equipment;
And step 203, scheduling other frequency domain resources except the specific frequency domain resource in the frequency domain resources for the edge terminal equipment.
In some optional embodiments of the present invention, the determining the edge terminal device includes detecting a signal receiving power of the terminal device, determining whether the signal receiving power is smaller than a third preset threshold, and determining the terminal device with the signal receiving power smaller than the third preset threshold as the edge terminal device.
In this embodiment, after receiving the first notification message sent by the first network device, the second network device schedules the edge terminal device within the coverage area, and does not schedule the specific frequency domain resource included in the first notification message, that is, the edge terminal device in the public network cannot use the specific frequency domain resource, so as to avoid interference to the terminal device in the private network if the edge terminal device possibly approaching the private network uses the specific frequency domain resource.
In this embodiment, the second network device may detect the signal receiving Power of each terminal device, where the signal receiving Power may be, for example, reference signal receiving Power (RSRP, reference Signal Receiving Power), determine whether the signal receiving Power is greater than a third preset threshold, if the signal receiving Power is greater than the third preset threshold, it may indicate that the terminal device is closer to the second network device and the terminal device is in a central area within the coverage area of the second network device, otherwise, if the signal receiving Power is less than or equal to the third preset threshold, it may indicate that the terminal device is farther from the second network device and the terminal device is in an edge area within the coverage area of the second network device, and the corresponding terminal device may be referred to as an edge terminal device.
In some optional embodiments of the invention, the method further comprises scheduling, for other terminal devices than the edge terminal device, the frequency domain resource for the other terminal devices, the other terminal devices being other terminal devices than the edge terminal device that establish a connection with the second network device.
In this embodiment, for the edge terminal device in the public network, the specific frequency domain resource is not scheduled for the edge terminal device, but other frequency domain resources except for the specific frequency domain resource in the frequency domain resources configured at the network side can be scheduled for the edge terminal device. For the terminal device in the central area of the coverage (i.e. the other terminal devices), since the other terminal devices are far away from the private network, the second network device may schedule the frequency domain resources (including the specific frequency domain resources) configured on the network side for the other terminal devices.
In some optional embodiments of the invention, the method further comprises the step that the second network device receives a second notification message sent by the first network device, wherein the second notification message is used for releasing the specific frequency domain resource, and the frequency domain resource is scheduled for the edge terminal device based on the second notification message.
In this embodiment, the second network device releases the specific frequency domain resource, which means that the second network device may schedule the frequency domain resource including the specific frequency domain resource for the edge terminal device. It is understood that the second network device may schedule the particular frequency domain resource for the edge terminal device.
According to the technical scheme, when the resource demand of the first network equipment is large, the specific frequency domain resource is preferentially used, and the second network equipment is informed not to schedule the specific frequency domain resource for the edge terminal equipment (namely, the second network equipment is informed that the specific frequency domain resource is the frequency domain resource special for the first network equipment), so that interference of the edge terminal equipment possibly approaching to the special network in the public network to the terminal equipment in the special network is avoided if the specific frequency domain resource is used, and the interference between networks is reduced under the condition that the same-frequency networking of the special network and the public network is realized.
Embodiments of the present invention are described below with reference to specific examples. In the following embodiments, the private network corresponds to a first network device, the terminal device under the private network is denoted as a first terminal device, the public network corresponds to a second network device, and the terminal device under the public network is denoted as a second terminal device.

Step 301, the first network device detects that the number of RRC connections within the first preset duration reaches a first preset threshold, and executes step 302.
The first network device detects that the number of RRC connections within a first preset duration reaches a first preset threshold, which may indicate that there are more users accessing the private network at present, and the resource requirement of the private network increases suddenly.
Step 302, the first network device sends a first notification message to the second network device, where the first notification message includes a specific frequency domain resource configured by the network side.
In this embodiment, the network side device configures a specific frequency domain resource for the first network device in advance, where the specific frequency domain resource is preferentially used by a user of the private network under some circumstances, for example, under a sudden increase in the number of users of the private network.
Step 303, the second network device does not schedule the specific frequency domain resource for the edge terminal device based on the first notification message.
The second network device does not schedule the specific frequency domain resource for the edge terminal device, which can be understood that the second network device may schedule other frequency domain resources except the specific frequency domain resource in the frequency domain resources for the edge terminal device. In addition, the second network device may schedule the frequency domain resources for a non-edge terminal device (e.g., a terminal device in a central area), where the scheduled frequency domain resources include the specific frequency domain resources described above.
Step 304, the first network device detects that the number of RRC connections in the second preset duration is smaller than a second preset threshold, and performs step 305.
The first network device detects that the number of RRC connections in the second preset duration is smaller than a second preset threshold, which may indicate that there are fewer users accessing the private network, and the resource requirement of the private network drops.
Step 305, the first network device sends a second notification message to the second network device, where the second notification message is used to release the specific frequency domain resource.
The second notification message may include the specific frequency domain resource, or the second notification message may include a specific identifier, where the specific identifier is used to indicate that the specific frequency domain resource is released.
Step 306, the second network device may schedule the frequency domain resource for the edge terminal device, where the frequency domain resource may include the specific frequency domain resource.
Example two
Fig. 4 is a second schematic diagram of an interaction flow of an information processing method according to an embodiment of the present invention, where, as shown in fig. 4, the method includes:
Step 401, the first network device detects that the number of RRC connections within a first preset duration reaches a first preset threshold, and executes step 402.
The first network device detects that the number of RRC connections within a first preset duration reaches a first preset threshold, which may indicate that there are more users accessing the private network at present, and the resource requirement of the private network increases suddenly.
Step 402, the first network device sends a request message to the second network device, where the request message is used to request load information of the second network device.
In this embodiment, the load information may specifically be a current uplink and downlink PRB occupancy of the second network device, and of course, the load information in this embodiment is not limited to the PRB occupancy, and other information capable of indicating the load condition of the second network device may also be within the protection scope of the embodiment of the present invention.
Step 403, the first network device obtains the load information fed back by the second network device.
And 404, the first network equipment takes the highest load based on the load information fed back by each second network equipment, and determines specific frequency domain resources based on the highest load and the first frequency domain resources configured on the network side.
In this embodiment, the implementation manner of determining the specific frequency domain resource based on the current load of the second network device may be described in the foregoing embodiment, which is not described herein.
Step 405, the first network device sends a first notification message to the second network device, where the first notification message includes the specific frequency domain resource.
Step 406, the second network device does not schedule the specific frequency domain resource for the edge terminal device based on the first notification message.
The second network device does not schedule the specific frequency domain resource for the edge terminal device, which can be understood that the second network device may schedule other frequency domain resources except the specific frequency domain resource in the frequency domain resources for the edge terminal device. In addition, the second network device may schedule the frequency domain resources for a non-edge terminal device (e.g., a terminal device in a central area), where the scheduled frequency domain resources include the specific frequency domain resources described above.
Step 407, the first network device detects that the number of RRC connections in the second preset duration is smaller than a second preset threshold, and performs step 408.
The first network device detects that the number of RRC connections in the second preset duration is smaller than a second preset threshold, which may indicate that there are fewer users accessing the private network, and the resource requirement of the private network drops.
Step 408, the first network device sends a second notification message to the second network device, where the second notification message is used to release the specific frequency domain resource.
The second notification message may include the specific frequency domain resource, or the second notification message may include a specific identifier, where the specific identifier is used to indicate that the specific frequency domain resource is released.
Step 409, the second network device may schedule the frequency domain resource for the edge terminal device, where the frequency domain resource may include the specific frequency domain resource.
In the above two examples of the invention, the scheduling of the available resources for the traffic channels of the private or public cell may comprise the following ways:
In a first manner, the network device (including the first network device and the second network device shown in fig. 3 and fig. 4) sends an RRC reconfiguration message to the terminal devices (for example, the first terminal device and the second terminal device) in the coverage area, where the RRC reconfiguration message includes updated frequency domain resources to notify the terminal devices to reconfigure the frequency domain resources, where the RRC reconfiguration message sent by the first network device to the first terminal device includes the specific frequency domain resources for the first terminal device of the private network, and where the RRC reconfiguration message sent by the second network device to the second terminal device in the coverage edge may include other frequency domain resources except the specific frequency domain resources for the second terminal device of the public network. For example, the frequency domain resource configured by the network side for the first network device and the second network device is W, the specific frequency domain resource is W1, if w=w1+w2 exists, W2 can be understood as other frequency domain resources except the specific frequency domain resource in the frequency domain resources, the RRC reconfiguration message sent by the first network device to the first terminal device can include W1, and the RRC reconfiguration message sent by the second network device to the second terminal device at the coverage edge can include W2.
For example, the terminal device is informed to reconfigure the bandwidth or the bandwidth part (BWP), and the CSI-RS and SRS frequency domain positions are updated along with the reconfiguration of the frequency domain resources, and each uses the CQI feedback to schedule the traffic channel.
In the second mode, the frequency domain resources of the terminal equipment are not reconfigured, and the CQI is fed back by adopting the frequency domain resources configured by the network side. The CQI feedback illustratively corresponds to the full band (full band representing the full bandwidth) of the network side configuration.
The third mode is that the frequency domain resource of the terminal equipment is not reconfigured, the terminal equipment adopts a sub-band CQI feedback mode configured by a network side, and the CQI feedback corresponds to the sub-band configured by the network side, wherein the sub-band is a part configured by the network side and corresponds to the full band, and it can be understood that the full band can be divided into a plurality of sub-bands in advance.
In the case of performing RRC reconfiguration on the terminal device in the first manner, after the first network device detects that the number of current users is small, that is, after executing step 304 in fig. 3 or step 407 in fig. 4, the first network device and the second network device need to notify the terminal device to restore the original frequency domain resources through the RRC reconfiguration message again. For example, the RRC reconfiguration message sent by the first network device to the first terminal device may include W, the RRC reconfiguration message sent by the second network device to the second terminal device located at the coverage edge may include W, or the RRC reconfiguration messages sent by the first network device and the second network device to the terminal devices in the respective coverage areas may include specific indication information, where the specific indication information is used to indicate that the originally configured frequency domain resource W is restored.
