In order to facilitate understanding of the embodiments of the present application, terms or process flows involved in the embodiments of the present application are briefly described below.

1) Communication perception integration (INTEGRATED SENSING AND communications, ISAC)

The ISAC integrates the communication function and the perception function, so that a future communication system has the communication function and the perception function, and physical characteristics of surrounding environment are perceived through active cognition and analysis of characteristics of a channel when a wireless channel transmits information, so that mutual enhancement of the communication function and the perception function is realized. Communication refers to the transmission of information between two communication devices or between multiple communication devices. Sensing refers to detecting parameters of a physical environment, such as ranging, speed measurement, etc., based on communication signals. As shown in fig. 2, the terminal can sense surrounding environment information by using the transmitting signal of the terminal, and assist in designing a communication link to avoid some obstacles (such as automobiles), so as to improve communication performance.

ISACs employ a signal that satisfies both communication and perception requirements. Such as an orthogonal frequency division multiplexed (orthogonal frequency division multiplexing, OFDM) signal. The ISAC transmitter transmits an OFDM signal to a perception target to be perceived, the OFDM signal is reflected by the perception target to generate an echo signal, and time delay exists between the echo signal and the transmission signal. At the ISAC receiver, a range profile is obtained by performing time-domain or frequency-domain digital signal processing on the echo signal and the transmission signal, then a time delay estimated value is obtained by searching a peak value in the range profile, and finally the distance of the perception target is determined based on the time delay estimated value.

2) Perception task

The perceived task is a task that invokes terminal and/or network side computing resources to handle (similar to QoS flow in 5G networks).

The perception tasks may include, among other things, sensing data of the motion/behavior of objects, such as detection of vehicle/drone motion through communication perception in a smart highway scene. The perception task may also include target recognition, for example, recognition of the type of object through communication perception. Only exemplary illustrations are provided herein.

In addition, based on the requirements of different sensing task sensing results, different task types can be classified according to the instantaneity and the accuracy of the sensing results, for example, the accuracy requirement on the creation of a precise map is high, and the instantaneity requirement on the location of a target location is high.

It should be noted that the computational resources required for perceived tasks of the same task type are typically the same, and the computational resources required for perceived tasks of different task types are different. For example, the computing resource required for the perceived task corresponding to task type 1 is a, the computing resource required for the perceived task corresponding to task type 2 is B, and a and B are not the same. In particular applications, there may be one or more perceived tasks of the same task type, where the computational resources required for multiple perceived tasks of the same task type may be different. For example, task type 1 corresponds to perceived task 1 through perceived task 3, where the computational resources required for perceived task 1 are X, the computational resources required for perceived task 2 are Y, and the computational resources required for perceived task 3 are Z, where X, Y and Z are different. Without being particularly limited thereto, it is to be understood in connection with a particular application.

In addition, one Application (APP) may initiate multiple perception tasks for the same task type, for example, construct a map of region a (precision in the order of hundred meters, scale 1:10) based on the perception data of the terminal, and construct a map of region B (precision in the order of hundred meters, scale 1:10) based on the perception data of the terminal. Multiple applications may also initiate multiple awareness tasks of the same traffic type, for example, application 1 initiates construction of a map of region a (precision in kilometers scale 1:100) based on awareness data of the terminal, and application 2 initiates construction of a map of region a (precision in kilometers scale 1:100) based on awareness data of the terminal. The illustrations are only exemplary and are not intended to be limiting in any way.

3) Awareness session

The aware session is a session established between the terminal and the aware management network function for carrying the aware tasks (similar to PDU sessions in 5G networks) and reserves the required resources for the carried aware tasks. In creating the aware session, a transport channel (similar to a tunnel in a PDU session) is created between the terminal and the aware management network function. Wherein one perception session may carry one or more perception tasks. The parameter information that the perception session can carry includes a task type of the perception task. After the creation of the perception session is completed, the perception task can be carried, and once congestion, service variation and the like occur, the terminal or the perception management network function can modify or release the perception session.

The application provides a communication method under the condition of applying the network architecture of fig. 1, so as to realize the cooperative processing of the sensing task of the terminal and the network. In order to better illustrate the solution of the present application, the following description is divided into two examples. The first embodiment is a specific scheme of a sensing strategy for directly requesting a network to assist the terminal to execute a sensing task. The second embodiment is a specific scheme for directly requesting to establish a sensing task cooperatively executed by the end network. The first terminal in the following specific embodiments may be the first terminal itself or may be a chip inside the first terminal. The first access device may be the first access device itself or a chip inside the first access device, and the first access device may be a device formed by combining CU and DU, may be CU or DU, may also be a gNB, or the like, and is not particularly limited herein. The first network element is for data management of the awareness task, e.g. awareness management network functions. The second network element is used for distribution of messages, e.g. signaling distribution network functions. The description is given here by way of example only and is not particularly limiting.

Embodiment one, a terminal directly requests a network to assist the terminal to execute a sensing strategy of a sensing task

The following describes the technical scheme of the present application in detail with reference to fig. 3 by way of a specific method embodiment. It should be noted that fig. 3 is a schematic flow chart of a method embodiment of the present application, showing detailed communication steps or operations of the method, but these steps or operations are only examples, and other operations or variations of the various operations in fig. 3 may also be performed by the embodiment of the present application. Furthermore, the various steps in fig. 3 may be performed in a different order than presented in fig. 3, respectively, and it is possible that not all of the operations in fig. 3 are to be performed. Fig. 3 illustrates data interactions between a first terminal, a first access device, a second network element, a first network element, and a perception processing node. In fig. 3, taking a first terminal as UE1, a first access device as gNB1, a second network element as a signaling distribution network function, and a first network element as a perception management network function as an example, the following is performed:

In step 301, UE1 sends a fourth message to the signaling distribution network function through the gNB1, where the fourth message is used to request the network (i.e. the network element of the core network, or the network function called the core network) to perform a sensing policy of a sensing task in cooperation with UE 1.

The fourth message may be a new type of message, where the fourth message is associated with a sensing policy of the requested sensing task, and based on the fourth message, the sensing policy of the requested sensing task may be determined. Or the fourth message is a session (i.e., aware session) setup request message. Or the fourth message is an NAS message, and the establishment request message and the perception policy request indication information of the perception session are carried in the NAS message, so that the network function of the core network determines to execute the acquisition of the perception policy. Or the NAS message comprises a request message and a request type for setting up the aware session, wherein the request type indicates that the purpose of setting up the aware session is to request the aware policy. The present invention is not particularly limited herein.

Optionally, the fourth message includes a type of the perceived task such that the signaling distribution network function obtains the type of perceived task and then knows to distribute the fourth message to the perceived management network function. Further, when the fourth message includes a type of a aware task, a aware policy of the aware task may be requested by default. The perception tasks can be divided into a perception task for identifying the motion behavior and a perception task for identifying the target according to the perception requirements, and can be further divided into a real-time perception task and a non-real-time perception task according to the perception results. The computing resources required for different types of perceived tasks are typically different, and the perceived function may allocate different computing resources based on the type of perceived task.

Optionally, the fourth message further comprises one or more of an identification of the perceived task, a computational resource requirement of the perceived task, location information of the UE1, and the first indication information.

The identification of the sensing task is used for identifying a specific sensing task, for example, the sensing task is an unmanned aerial vehicle for identifying low-altitude flight, the identification of the corresponding sensing task is SENSIING-UAV, the sensing task is a map for constructing an area A, and the corresponding sensing task is SENSIING-mapA. The description is given here by way of example only and is not particularly limiting. When the identification of the perceived task is included in the fourth message, the perceived policy of which perceived task may be explicitly requested.

Wherein the computational resource requirements of the perceived task are used to identify the computational power requirements of the perceived task. Based on this, when the signaling distribution network function distributes the fourth message carrying the computing resource requirement of the perceived task to the perceived management network function, the perceived management network function distributes the perceived processing node satisfying the computing resource requirement of the perceived task to the UE1 to execute the corresponding perceived task. For example, the sensing task is target tracking, the required computational effort is 1P, the sensing task is map construction, the required computational effort is 2P, the sensing management network function can distribute the computational effort greater than or equal to 1P to the target tracking to the sensing processing nodes for executing the target tracking, and the sensing management network function can construct the map distribution to the sensing processing nodes with the computational effort greater than or equal to 2P for executing the map construction. The illustrations are only exemplary and are not intended to be limiting in any way.

When the fourth message includes the location information of the UE1, the signaling distribution network function may conveniently distribute the fourth message to the sensing management network function, where the sensing management network function may select a sensing processing node closer to the UE1 for the UE1, so as to avoid wasting data transmission overhead.

Wherein the first indication information indicates data calculation of a perceived task performed by the network, or data calculation of a perceived task not performed by the UE1, or data calculation of a partial perceived task performed by the UE 1. Based on this, when the signaling distribution network function distributes the fourth message to the perception management network function, the perception management network function may determine how to perform the perception task with reference to the first indication information. For example, the sensing task is to construct a map, and the first indication information may indicate that after the network acquires the sensing data reported by the UE1, calculation (e.g., statistics, clustering, etc.) of the sensing data is performed to acquire the map. Or the first indication information may indicate that the UE1 does not perform data computation (e.g., statistics, clustering, etc.) of the sensing task, then the network performs data computation of the sensing task. Or the first indication information may indicate that the UE1 performs data calculation of a part of the sensing task (for example, the UE1 generates sensing data after sensing the surrounding area based on communication sensing, and clusters the sensing data), and then the network performs data calculation of other parts of the sensing task (for example, performs data calculation on the clustered sensing data to obtain a map). Only exemplary illustrations are provided herein.

It should be noted that the specific information included in the fourth message may be included in a container, and the UE1 may directly send the container to the signaling distribution network function, where the signaling distribution network function does not parse the container, and directly carries the container in the first message and sends the container to the perception management network function. The signaling distribution network function may also parse the container, add information items of information to form a new container, and send the new container carried in the first message to the perception management network function.

In step 302, the signaling distribution network function sends a first message to the awareness management network function according to the fourth message, where the first message is used to request the network to cooperatively execute the awareness policy of the awareness task with the UE 1.

The first message may be a new type of message, where the first message is associated with a sensing policy of the requested sensing task, and the sensing policy of the requested sensing task may be determined based on the first message. Or the fourth message is a session (i.e., aware session) setup request message. Or the first message carries the establishment request message of the perception session and the perception policy request indication information, so that the network function of the core network determines to execute the acquisition of the perception policy. Or the first message comprises a request message and a request type for setting up the perception session, wherein the request type indicates that the purpose of setting up the perception session is to request the perception policy. The present invention is not particularly limited herein.

It should be noted that, when the location information of the UE1 is not included in the fourth message, the signaling distribution network function may also acquire the location information of the UE1 based on the registration information of the UE1, or acquire the location information of the UE1 based on the location management function. When the first message includes the location information of the UE1 and the type of the sensing task, the sensing management network element is used for distributing sensing processing nodes which are closer to the UE1 and meet the requirement of the sensing task for the UE 1.

Note also that, typically, the information included in the first message is the same as the information included in the fourth message, but regardless of whether the location information of UE1 is included in the fourth message, the location information of UE1 is included in the first message.

In addition, when the perception task is created, the binding relation between the signaling distribution network function and the perception management network function already exists, and based on the binding relation, the signaling distribution network function can clearly send the first message to which perception management network function after receiving the first message. For example, the sensing task 1 corresponds to the sensing management network function 1, the sensing task 2 corresponds to the sensing management network function 2, and the signaling distribution network function receives a fourth message, where the signaling distribution network function may send the first message to the sensing management network function 1 when the fourth message is used to request the network element to cooperatively execute the sensing policy of the sensing task 1 with the UE 1. The description is given here by way of example only and is not particularly limiting.

In step 303, the awareness management network function obtains a first awareness policy according to the first message, the first awareness policy including an identification of a target awareness processing node for performing the awareness task.

It should be noted that, before executing step 303, the awareness management network function further obtains capability information of at least one awareness processing node and location information of at least one awareness processing node, and determines a target awareness processing node according to the first message, the capability information of at least one awareness processing node and the location information of at least one awareness processing node, where the target awareness processing node is used for data calculation of an awareness task.

In one example, the aware processing node may register capability information of the aware processing node (processing capabilities of a central processing unit (central processing unit, CPU), graphics processing unit (graphics processing unit, GPU), scheduling capabilities of multi-threaded tasks, latency, bandwidth, etc. of the aware processing node) and location information of the aware processing node with the aware management network function so that the aware management network function obtains the capability information of the aware processing node and the location information of the aware processing node. In another example, the awareness management network function may request capability information of the awareness processing node and location information of the awareness processing node from the awareness processing node.

When the first message includes location information of the UE1 and a type of the perceived task, the perceived management network function may determine computing resources required for the perceived task based on the type of the perceived task. A determination is made as to whether the sensing processing node is available for performing data calculations of the sensing task based on the capability information of the sensing processing node. A target sensing node that can perform a sensing task is selected based on the location information of the UE1 and the location information of the sensing processing node. For example, the type of the sensing task is target positioning, the computing resource required by the target positioning is X, the sensing processing nodes capable of providing the X computing resource comprise sensing processing nodes 1 to N, the sensing processing nodes of which the positions from the UE1 to the sensing processing nodes 1 to N are smaller than the distance threshold value are sensing processing nodes 3 to 5, and then the sensing management network function can take the sensing processing nodes 3 to 5 as target sensing processing nodes. The description is given here by way of example only and is not particularly limiting. When the identification of the perceived task is included in the fourth message, the perceived policy of which perceived task may be explicitly requested. When the fourth message includes the computing resource requirement of the sensing task, the sensing management network function allocates the sensing processing node meeting the computing resource requirement of the sensing task to the UE1 to execute the corresponding sensing task.

When the first message includes first indication information, the awareness management network function may determine a first awareness policy with reference to the first indication information. For example, the first indication information indicates data computation of a perception task performed by the network, the perception management network function determines a target perception processing node based on capability information of the perception processing node, location information of the perception processing node, and location information of the UE1, and determines a specific task item performed by the target perception processing node. Only exemplary illustrations are provided herein.

Optionally, the first awareness policy is related to at least one of the following information:

the configuration policy of UE1, the configuration policy of the network, the capability information of the target processing node, the location information of UE1, or the location information of the target processing node.

The sensing configuration policy of the UE1 may be understood as a sensing policy configured by the UE1, for example, the UE1 reports sensing data, the network performs data analysis of the sensing data to obtain sensing results, or the UE1 performs cluster analysis on the sensing data to obtain cluster sensing data, reports the cluster sensing data to the network, and the network performs data calculation of the cluster sensing data to obtain sensing results, which are only illustrated herein and not particularly limited.

The configuration policy of the network may be understood as a self-configured sensing policy of the network, for example, data calculation is performed by using a sensing processing node with a computing resource X for a sensing task with a type 1 of sensing task, which is only illustrated herein and not particularly limited.

Optionally, the first sensing policy further comprises that the UE1 performs a first part of the sensing tasks and/or that the target sensing processing node performs a second part of the sensing tasks. Based on this, the UE1 can make clear how to perform the perceived task, the first partial task and the second partial task constituting the perceived task.

In addition, it is further noted that the first message is a session establishment request message, and the first awareness policy further includes an identification of a session corresponding to the awareness task. The application establishes the perception strategy that the conversation request network and the first terminal cooperatively execute the perception task, can open the path from the network side to the terminal side, saves signaling cost, reasonably schedules the resources of the network side and the terminal side to process the perception task, and improves the processing efficiency. In addition, the first message is a sensing session establishment request message, and the network and the UE1 are requested to cooperatively execute a sensing policy of a sensing task through the sensing session establishment request message, and the first sensing policy includes a session identifier corresponding to the sensing task, and a subsequent sensing task may carry a session identifier to multiplex a communication resource (e.g., a tunnel, etc.) corresponding to the session, so that data processing efficiency is improved.

Step 304, the awareness management network function sends a first awareness policy to the signaling distribution network function.

In step 305, the signaling distribution network function sends a first awareness policy to the UE 1.

It should be noted that, after the UE1 receives the first sensing policy, when the sensing task is executed subsequently, data related to the sensing task (for example, the sensing data or the cluster sensing data described above) may be directly reported to the target sensing processing node, the target sensing processing node obtains a sensing result after processing is completed, and then the target sensing processing node may send the sensing result to the UE1.

In step 306, ue1 reports data related to the sensing task to the target sensing processing node.

In step 307, the target sensing processing node performs data processing on the data related to the sensing task to obtain a sensing result.

In step 308, the target awareness processing node sends the awareness result to the UE 1.

Based on the requirements of the perceived task processing, the UE1 or the perceived management network function may initiate a modification flow of the perceived task. For example, the computational resources of the target aware processing node have changed, or UE1 requests more computational resources for the aware task, etc.

In addition, after the required processing of the sensing task is completed, the UE1 or the sensing management network function may initiate a release procedure of the sensing task, and the sensing management network function and the sensing processing node release corresponding computing resources.

In the second embodiment, the terminal directly requests to establish the sensing task cooperatively executed by the end network

The following describes the technical scheme of the present application in detail with reference to fig. 4 by using a specific method embodiment. It should be noted that fig. 4 is a schematic flow chart of a method embodiment of the present application, showing detailed communication steps or operations of the method, but these steps or operations are only examples, and other operations or variations of the various operations in fig. 4 may also be performed by the embodiment of the present application. Furthermore, the various steps in fig. 4 may be performed in a different order than presented in fig. 4, respectively, and it is possible that not all of the operations in fig. 4 are to be performed. Fig. 4 illustrates data interactions between a first terminal, a first access device, a second network element, a first network element, and a perception processing node. In fig. 4, taking a first terminal as UE1, a first access device as gNB1, a second network element as a signaling distribution network function, and a first network element as a perception management network function as an example, the following is performed:

in step 401, UE1 sends a fifth message to the signaling distribution network function via the gNB1, the fifth message being used to trigger creation of the first sensing task of UE 1.

Wherein the fifth message may be a new type of message, the fifth message being associated with a request to create the first perceived task, and based on the fifth message it may be determined that the request to create the first perceived task is present. Or the fifth message is a session (i.e., aware session) setup request message. Or the fifth message is a NAS message, and the establishment request message of the perception session and the creation request indication information of the perception task are carried in the NAS message, so that the network function of the core network determines to execute the creation of the perception task. Or the NAS message includes a request message for setting up a aware session and a request type, where the request type indicates that the purpose of setting up the aware session is to request to create a first aware task. The present invention is not particularly limited herein.

Optionally, the fifth message includes a type of the first sensing task, so that after the signaling distribution network function obtains the type of the sensing task, the signaling distribution network function knows to distribute the fifth message to the sensing management network function according to a first correspondence (the first correspondence indicates a correspondence between the type of the first sensing task and the sensing management network function, for example, the sensing management network function corresponding to the type 1 of the first sensing task is 1, the sensing management network function corresponding to the type 2 of the first sensing task is 2, and so on, which is only illustrated herein). Further, when the fifth message includes a type of the first perceived task, creation of the first perceived task may be requested by default.

Optionally, the fifth message further comprises one or more of location information of the UE1, computational resource requirements of the first perceived task, second indication information, and an identification of a session for carrying the first perceived task.

Wherein the computational resource requirements of the first perceived task are used to characterize the computational power requirements of the first perceived task. Based on this, when the signaling distribution network function distributes the fifth message to the perception management network function, the perception management network function performs the corresponding perception task for the perception processing node that the UE1 distributes the computing resource demand satisfying the perception task.

The computing resource requirement of the first sensing task is used for identifying the computing power requirement of the first sensing task, and based on the computing resource requirement, when the signaling distribution network function distributes the fifth message to the sensing management network function, the sensing management network function distributes the sensing processing node meeting the computing resource requirement of the sensing task for the UE1 to execute the corresponding sensing task. For example, the first sensing task is target tracking, the required computational effort is 1P, the first sensing task is map construction, the required computational effort is 2P, the sensing management network function can perform target tracking for the sensing processing nodes with the computational effort greater than or equal to 1P for target tracking, and the sensing management network function can construct map construction for the sensing processing nodes with the computational effort greater than or equal to 2P for map construction. The illustrations are only exemplary and are not intended to be limiting in any way.

The second indication information is used for indicating data calculation of the first sensing task performed by the network, or data calculation of the first sensing task not performed by the UE1, or data calculation of part of the first sensing task performed by the UE 1. Based on this, when the signaling distribution network function distributes the fifth message to the perception management network function, the perception management network function may determine how to perform the perception task with reference to the second indication information. It is understood that the description related to the first indication information is referred to above, and is not explained here.

It should be noted that the specific information included in the fifth message may be included in a container, and the UE1 may directly send the container to the signaling distribution network function, without parsing the container, and directly carry the container in the second message and send the container to the perception management network function. The signaling distribution network function may also parse the container, add information items of information to form a new container, and send the new container carried in a second message to the perception management network function.

In step 402, the signaling distribution network function sends a second message to the awareness management network function according to the fifth message, where the second message is used to trigger creation of the first awareness task of the UE 1.

Wherein the second message may be a new type of message, the second message being associated with a request to create the first perceived task, the request to create the first perceived task being determined based on the second message. Or the second message is a session (i.e., a aware session) setup request message. Or the second message is a NAS message, and the establishment request message of the perception session and the establishment request indication information of the perception task are carried in the NAS message, so that the network function of the core network determines to execute the establishment of the perception task. Or the NAS message includes a request message for setting up a aware session and a request type, where the request type indicates that the purpose of setting up the aware session is to request to create a first aware task. The present invention is not particularly limited herein.

It should be noted that, when the location information of the UE1 is not included in the second message, the signaling distribution network function may also acquire the location information of the UE1 based on the registration information of the UE1, or acquire the location information of the UE1 based on the location management function. When the second message includes the location information of the UE1 and the type of the sensing task, the sensing management network element is used for distributing sensing processing nodes which are closer to the UE1 and meet the requirement of the sensing task for the UE 1.

It is also noted that, generally, the information included in the second message is the same as the information included in the fifth message, but regardless of whether the location information of UE1 is included in the fifth message, the location information of UE1 is included in the second message.

In step 403, the perception management network function obtains first information according to the second message, where the first information includes an identifier of the first perception task and an identifier of the first target perception processing node for executing the first perception task.

It should be noted that, before executing step 403, the awareness management network function further obtains capability information of at least one awareness processing node and location information of at least one awareness processing node, and determines a first target awareness processing node according to the second message, the capability information of at least one awareness processing node and the location information of at least one awareness processing node, where the first target awareness processing node is used for data calculation of the first awareness task.

In one example, the aware processing node may register capability information of the aware processing node (processing capabilities of the CPU, GPU, scheduling capabilities of the multithreaded tasks, latency, bandwidth, etc. of the aware processing node) and location information of the aware processing node with the aware management network function so that the aware management network function obtains the capability information of the aware processing node and location information of the aware processing and nodes. In another example, the awareness management network function may request capability information of the awareness processing node and location information of the awareness processing node from the awareness processing node.

When the second message includes location information of the UE1 and a type of the perceived task, the perceived management network function may determine computing resources required for the first perceived task based on the type of the perceived task. A determination is made as to whether the sensing processing node is available for performing data calculations of the sensing task based on the capability information of the sensing processing node. A target sensing node that can perform a sensing task is selected based on the location information of the UE1 and the location information of the sensing processing node. It will be understood that the description is not expanded herein with reference to the relevant description in step 303 above.

When the fifth message includes second indication information, the awareness management network function may determine how to perform the first awareness task with reference to the second indication information. For example, the second indication information indicates data calculations for performing a perceived task by the network, the perceived management network function determines a first target perceived processing node based on the capability information of the perceived processing node, the location information of the perceived processing node, and the location information of the UE1, and determines a specific task item to be performed by the first target perceived processing node. Only exemplary illustrations are provided herein.

Optionally, the first information further includes a second awareness policy, where the second awareness policy instructs the UE1 to perform a first part of the first awareness task and/or the first target awareness processing node to perform a second part of the first awareness task. Based on this, the UE1 can make clear how to perform the perceived task, the first partial task and the second partial task constituting the first perceived task.

In addition, the second message is a session establishment request message, and the second awareness policy further includes an identification of a session corresponding to the first awareness task. The application establishes the perception strategy that the conversation request network and the first terminal execute the first perception task cooperatively, can open the path from the network side to the terminal side, saves signaling cost, reasonably schedules the resources of the network side and the terminal side to process the first perception task, and improves the processing efficiency. In addition, the second message is a session establishment request message, and the network and the UE1 are requested to cooperatively execute a sensing policy of the first sensing task through the session establishment request message, and the second sensing policy includes a session identifier corresponding to the first sensing task, and the subsequent first sensing task may carry a session identifier to multiplex a communication resource (such as a tunnel or the like) corresponding to the session, so that data processing efficiency is improved.

Illustratively, the first information is related to at least one of:

The configuration policy of UE1, the configuration policy of the network, the capability information of the target processing node, the location information of UE1, or the location information of the first target processing node.

The sensing configuration policy of the UE1 may be understood as a sensing policy configured by the UE 1. For example, the UE1 reports the sensing data, the network performs data analysis of the sensing data to obtain a sensing result, or the UE1 performs cluster analysis on the sensing data to obtain cluster sensing data, reports the cluster sensing data to the network, and the network performs data calculation of the cluster sensing data to obtain a sensing result. The description is given here by way of example only and is not particularly limiting.

Step 404, the awareness management network function sends the first information to the signaling distribution network function.

In step 405, the signaling distribution network function sends first information to the UE 1.

It should be noted that, after the UE1 receives the first information, when the first sensing task is executed subsequently, data (for example, the sensing data or the cluster sensing data described above) related to the first sensing task may be directly reported to the first target sensing processing node, and the sensing result may be obtained after the processing of the first target sensing processing node is completed, and the sensing result may be sent to the UE1.

In step 406, ue1 reports data related to the first sensing task to the first target sensing processing node.

In step 407, the first target sensing processing node performs data processing on the data related to the first sensing task to obtain a sensing result.

In step 408, the first target awareness processing node sends an awareness result to the UE 1.

Based on the requirements of the first perceived task processing, the UE1 or the perceived management network function may initiate a modification flow of the first perceived task. For example, the computing resources of the first target aware processing node have changed, or UE1 requests more computing resources for the first aware task, etc. After the required first sensing task processing is completed, the UE1 or the sensing management network function may initiate a release procedure of the first sensing task, and the sensing management network function and the first target sensing processing node release corresponding computing resources.

For example, the following steps 409 to 410 may be referred to.

In step 409, the awareness management network function obtains the second target awareness processing node when the first condition is met.

Wherein the second target-aware processing node is typically different from the first target-aware processing node, but may be partially identical with respect to a particular application. The present invention is not particularly limited herein. For example, the first target sensing processing node is the sensing processing node 1, the sensing processing node 3 and the sensing processing node 5, the second target sensing processing node may be the sensing processing node 1 and the sensing processing node 4, or the second target sensing processing node is the sensing processing node 2, the sensing processing node 3 and the sensing processing node 5. The description is given here by way of example only and is not particularly limiting.

Illustratively, the first condition includes one or more of:

The awareness management network function receives a third message from the signaling distribution network function requesting modification of the first task. The third message includes computing resource demand change information of the first sensing task and/or third indication information, and the third indication information indicates to modify the first sensing task. It should be noted that the third message is typically triggered by a change in the computing resource requirements of the first perceived task or a change in the state of the first terminal.

Or the perception management network element acquires the state change information of the first target perception processing node, and determines that the first target perception processing node cannot execute the first perception task based on the state change information. The perception management network function can monitor the state of the first target perception processing node and periodically request the state change information of the first target perception processing node. In addition, when the first target sensing processing node is powered down, off-line or down, the first sensing task cannot be executed, or other tasks (possibly non-sensing tasks) currently processed by the first target sensing processing node occupy a large amount of computing resources of the first target sensing processing node, and the remaining computing resources of the first target sensing processing node are insufficient to support the computing of the first sensing task. The description is given here by way of example only and is not particularly limiting.

Whether the first perception task is modified or not is judged based on the specific requirement of the first perception task, and the computing resource for executing the first perception task is adjusted, so that the execution efficiency of the first perception task and the experience of the first perception task can be ensured based on the calculation resource.

In step 410, the awareness management network function sends a third awareness policy to the signaling distribution network function, where the third awareness policy includes a third portion of tasks performed by the UE1 in the first awareness task and/or a fourth portion of tasks performed by the second target awareness processing node in the first awareness task, where the third portion of tasks and the fourth portion of tasks form the first awareness task.

The third part of tasks in the first sensing task may be the same as the first part of tasks in the first sensing task, for example, to acquire sensing data based on communication sensing, and report the sensing data to the network, and correspondingly, the fourth part of tasks in the first sensing task may be the same as the second part of tasks in the first sensing task. The third partial task in the first sensing task may be the same as or different from the first partial task in the first sensing task, for example, the first partial task is to acquire sensing data based on communication sensing, report the sensing data to a network, the third partial task is to acquire sensing data based on communication sensing, perform clustering processing on the sensing data to obtain clustered sensing data, report the clustered sensing data to the network, and correspondingly, the fourth partial task in the first sensing task may be different from the second partial task in the first sensing task.

The third and fourth partial tasks are only exemplary and are not particularly limited herein.

In step 411, the signaling distribution network function sends the third awareness policy to UE 1.

It should be noted that, the third part of tasks in the first sensing task may be the same as or different from the first part of tasks in the first sensing task, and the second part of tasks in the first sensing task may be the same as or different from the fourth part of tasks in the first sensing task, which is flexibly determined in combination with the third sensing policy configured by the sensing management network function, which is not particularly limited herein.
