[0049] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0050] The technical solutions of this invention can be applied to various communication systems, such as GSM (Global System of Mobile communication), LTE (Long Term Evolution), or 5G systems. Optionally, a 5G system or 5G network can also be referred to as a New Radio (NR) system or NR network.

[0051] For example, the communication system used in this embodiment of the invention may include network devices and terminal devices (also referred to as terminals, communication terminals, etc.); the network device may be a device that communicates with the terminal device. The network device can provide communication coverage within a certain area and can communicate with terminals located within that area. Optionally, the network device may be a base station in various communication systems, such as an evolved Node B (eNB) in an LTE system, or a gNB in ​​a 5G or NR system.

[0052] It should be understood that devices with communication functions in the network / system of this application embodiment can be referred to as communication devices. Communication devices may include network devices and terminals with communication functions. Network devices and terminal devices can be the specific devices described above, which will not be repeated here. Communication devices may also include other devices in the communication system, such as network controllers, mobility management entities, and other network entities. This embodiment of the present invention does not limit these.

[0053] It should be understood that the terms "system" and "network" are often used interchangeably in this document. The term "and / or" in this document merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Furthermore, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0054] The terms “first,” “second,” etc., used in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0055] Before providing a detailed description of the technical solutions of the embodiments of the present invention, a brief explanation of communication sensing technology will be given first.

[0056] Sensing is the ability to perceive the physical environment or physical objects through base stations or other wireless sensing devices, achieving a function similar to radar. Currently, the development of communication network base stations has made it possible for air interfaces to achieve physical sensing.

[0057] Figure 1 This is a schematic diagram of the basic architecture of a communication sensing system; such as Figure 1 As shown, the SF network element responsible for sensing service processing can perform sensing service analysis and provide sensing results based on the received sensing requirements. Its deployment form can be independent deployment or co-deployed with 5G core network (5GC, 5G Core) network elements (such as Access and Mobility Management Function (AMF) or Location Management Function (LMF)). At the same time, according to the deployment requirements, SF can exist in two forms: Sensing Function-Control Plane (SF-C) and Sensing Function-User Plane (SF-U). Among them, SF-C can also be called the sensing control plane function, and SF-U can also be called the sensing data plane function.

[0058] The execution of sensing tasks can be achieved by sensing devices transmitting and receiving signals to initially acquire sensing information. These sensing devices may include radio access network equipment that is a 3GPP (3rd Generation Partnership Project) device, such as a base station; and / or, the sensing devices may also include non-3GPP devices connected to the radio access network equipment. In this embodiment of the invention, any non-3GPP device capable of performing sensing tasks can be used as a sensing device.

[0059] In the case where the sensing device is a radio access network device (such as a base station) that is a 3GPP device, the sensing information can be acquired by the base station transmitting and receiving signals, or the base station and the terminal can cooperate to complete the transmission and reception of signals, thereby acquiring the sensing signal. The acquired sensing signal is processed by the base station to generate sensing data, and the sensing data is processed by SF to form the sensing result.

[0060] Based at least on the above system architecture, the following embodiments of the present invention are proposed.

[0061] This invention provides a method for associative processing of perception tasks. Figure 2This is a flowchart illustrating the association processing method for perception tasks according to an embodiment of the present invention. Figure 1 ;like Figure 2 As shown, the method includes:

[0062] Step 101: The first network element generates or updates the first set based on the information of the sensing device corresponding to the sensing task; the first set includes at least one set of correspondences between sensing devices and sensing tasks;

[0063] Step 102: The first network element sends the first set to the second network element.

[0064] In this embodiment, the first network element is a control plane network element with sensing capabilities, and the second network element is a data plane network element with sensing capabilities. For example, the first network element can be a sensing-control plane (SF-C), and the second network element can be a sensing-user plane (SF-U), meaning the combination of the first and second network elements is responsible for sensing service processing. In some optional embodiments, the first and second network elements can be combined, meaning the first and second network elements are configured as a partial functional combination within the network element device, responsible for sensing service processing. In other optional embodiments, the first and second network elements can be deployed separately, meaning the first network element can be deployed in one network element device, and the second network element can be deployed in another network element device.

[0065] In some alternative embodiments, the second network element can be deployed according to its service area. The first network element can correspond to one or more second network elements. In the actual sensing service process, the first network element can locate the corresponding second network element by sensing the location of the service, thereby enabling the sensing device to establish a relevant link with the second network element and transmit sensing data.

[0066] In this embodiment of the invention, a first network element can generate or update a first set based on the information of the sensing device corresponding to the sensing task. The first set includes at least one set of correspondences between sensing devices and sensing tasks. For example, the first set may also be referred to as a first list, a first sensing task relationship set, a first sensing task relationship list, etc., containing correspondences, each including a sensing device and a corresponding sensing task. The first set is used to indicate the correspondence between sensing tasks and sensing devices.

[0067] As one example, the first set may include one or more sets of correspondences in the form of: index, sensing task identifier (ID), and sensing device information (such as the identifier of the sensing device). As another example, the first set may include one or more sets of correspondences in the form of: sensing device information (such as the identifier of the sensing device) and sensing task identifier (ID).

[0068] In this embodiment, the first network element sends the first set to the second network element, so that the second network element can associate the received sensing data with the sensing task corresponding to the corresponding sensing device according to the first set.

[0069] The technical solution of this invention allows the first network element in the control plane to generate a first set of correspondences between single or multiple sensing tasks and sensing devices, and supports operations such as generating and updating (merging, deleting) the first set, thereby enabling the first network element to manage the sensing tasks and corresponding sensing devices. The first network element sends the first set to the second network element in the user plane, enabling the second network element to perform association processing on the sensing data and the sensing tasks corresponding to the sensing devices based on the first set, thus realizing the association processing of single sensing data reported by the sensing devices with the sensing tasks.

[0070] In some optional embodiments of the present invention, the method further includes: the first network element receiving a first request from an application function via a first network function, the first request being used to initiate a sensing task, the first request including sensing task-related information; the sensing task-related information including one or more of the following: sensing task identifier, sensing service type, task area, refresh rate, and service area.

[0071] In this embodiment, when a sensing service is available, the Application Function (AF) can send a first request to the first network element. This first request is used to request the initiation of a sensing task. In other optional embodiments, the first request may also be referred to as a sensing request, a sensing service request, a sensing service request, or a request to initiate a sensing task, to initiate a sensing service process. The first request carries sensing task-related information, which includes one or more of the following: sensing task identifier, sensing service type, task area, refresh rate, and service area. The task area specifically refers to the execution area of ​​the sensing task. The refresh rate specifically refers to the frequency information of the sensing device performing the sensing task operation. In other optional embodiments, the first request may also include a first identifier, which is an application identifier used to identify an application or application type.

[0072] In this embodiment, the application function (AF) can send a first request to the first network element through a first network function. For example, in a 5G network, the first network function can be a network exposure function (NEF).

[0073] In some optional embodiments, the first network element is selected by the first network function. That is, after receiving the first request from the application function (AF), the first network function can select the first network element according to the perception task-related information carried in the first request. Specifically, it can select the first network element located in the service area according to the service area, or select the first network element whose service area range includes the service area. Then, the first network function sends the first request to the selected first network element.

[0074] It should be noted that the first request received by the first network function from the application function (AF) and the first request sent by the first network function to the first network element specifically refer to the same function and similar content carried by the requests, but the messages carrying the first requests may be different. Specifically, "same function" means that the first requests are both used to initiate a sensing task. "Same content" means that the content carried by the first requests includes sensing task-related information. "Similar content" can refer to the service area in the sensing task-related information of the first requests. In the case of the first request received by the first network function from the application function (AF), the service area carried in the first request can be represented by latitude and longitude; in the case of the first network function sending the first request to the first network element, the service area carried in the first request can be represented by a Tracking Area Code (TAC).

[0075] In some optional embodiments of the present invention, the method further includes: the first network element selecting a sensing device based on the sensing task-related information; correspondingly, the first network element generating or updating a first set based on the information of the sensing device corresponding to the sensing task, including: the first network element generating a first set based on the sensing task-related information and the selected sensing device.

[0076] In this embodiment, the first network element can select the corresponding sensing device (base station and / or terminal) based on the sensing task information. Specifically, the first network element can select the corresponding sensing device based on the task area and / or sensing type. If the first request is the first request received by the first network element, that is, if the first network element currently only receives one sensing task, a first set is generated based on the sensing task information carried in the first request and the selected sensing device.

[0077] In this way, the first network element of the control plane generates a first set of correspondences between a single sensing task and a sensing device, and sends the first set to the second network element. This enables the first network element to manage the sensing task and the corresponding sensing device, and enables the second network element of the user plane to perform association processing on the sensing data and the sensing task corresponding to the sensing device based on the first set. This realizes the association processing of the single sensing data reported by the sensing device with the sensing task.

[0078] In some optional embodiments of the present invention, the method further includes: the first network element selecting a second network element based on the selected sensing device and / or service area.

[0079] In this embodiment, the first network element may also select a second network element based on the selected sensing device and / or sensing task-related information (specifically, the service area). For example, the first network element may select a second network element based on the identifier or location of the selected sensing device, and / or, the first network element may also select a second network element based on the service area (which corresponds to the sensing device) in the sensing task-related information.

[0080] In some alternative embodiments, the first set includes at least one set of correspondences between sensing devices, sensing tasks, and second network elements.

[0081] In this embodiment, after the first network element selects the second network element, it can add the information of the second network element to the first set and the corresponding relationship of the sensing device associated with the second network element according to the correspondence between the sensing device and the second network element. That is, the first set may include at least one set of correspondence between sensing devices, sensing tasks and the second network element.

[0082] For example, the first set may include one or more sets of correspondences in the form of: index, sensing task identifier (ID), sensing device information (such as the identifier of the sensing device), and second network element information (such as the identifier of the second network element). As another example, the first set may include one or more sets of correspondences in the form of: sensing device information (such as the identifier of the sensing device), sensing task identifier (ID), and second network element information (such as the identifier of the second network element).

[0083] In this way, the first network element of the control plane can generate a first set according to the correspondence between the sensing task, the sensing device and the second network element, and send the first set to the second network element. This enables the first network element to manage the sensing task and the corresponding sensing device, and enables the second network element of the user plane to determine the sensing task or sensing data within its operating range based on the first set. Then, it can perform association processing on the sensing data and the sensing task corresponding to the sensing device, thus realizing the association processing of the single sensing data reported by the sensing device with the sensing task.

[0084] In some optional embodiments, generating the first set includes: the first network element determining the correspondence between at least one set of sensing devices and sensing tasks associated with the second network element, and generating the first set associated with the second network element;

[0085] Correspondingly, the first network element sends the first set to the second network element, including: the first network element sending the first set associated with the second network element to the second network element.

[0086] In this embodiment, if the correspondence also includes information about a second network element corresponding to a sensing device, the first network element can sort out the correspondence containing the information of the second network element based on the information of the second network element, and then generate a first set based on the correspondence containing the information of the second network element. In this case, the correspondence included in the first set are all correspondences associated with the second network element.

[0087] In this embodiment, the first network element sends the first set to the second network element, so that the second network element can associate the received sensing data with the sensing task corresponding to the corresponding sensing device according to the first set associated with it.

[0088] In this way, the first network element in the control plane can sort out the sensing tasks and / or sensing devices belonging to the operation scope of the second network element according to the correspondence between the sensing tasks, sensing devices and the second network element, thereby generating a first set corresponding to the second network element, and sending the first set to the second network element. This realizes the management of sensing tasks and corresponding sensing devices by the first network element, and enables the second network element in the user plane to perform association processing on sensing data and sensing tasks corresponding to sensing devices based on the first set, thus realizing the association processing of single sensing data reported by sensing devices with sensing tasks.

[0089] In some optional embodiments, the first network element sends the first set to the second network element, including: the first network element sending a second request to the second network element, the second request including the generated first set, the second request being used to initiate a sensing task.

[0090] In this embodiment, the second request is used to request the initiation of a sensing task. In other optional embodiments, the second request may also be called a sensing request, a sensing service request, a sensing service request, or a request to initiate a sensing task, in order to notify or request the second network element to initiate a sensing service process.

[0091] In this embodiment, the second request includes the first set, so that the second network element can associate the received sensing data with the sensing task corresponding to the corresponding sensing device based on the first set. In other optional embodiments, the second request may also include at least a portion of the sensing task-related information.

[0092] In some optional embodiments, the method further includes: the first network element receiving a second response corresponding to the second request sent by the second network element, the second response including relevant information of the second network element. The relevant information of the second network element is used to establish a link, bearer, or tunnel with the second network element. As one implementation, the relevant information of the second network element may specifically be tunnel information, port information, IP address information, interface information, etc. of the second network element. For example, the tunnel information may be a Tunnel Endpoint Identifier (TEID). This embodiment does not limit the type of relevant information of the second network element; any information that can establish a link or tunnel with the second network element is within the protection scope of this embodiment.

[0093] In some optional embodiments of the present invention, the method further includes: the first network element sending a third request to the sensing device, the third request being used to initiate a sensing task; and the first network element receiving a response from the sensing device corresponding to the third request.

[0094] In this embodiment, the third request is used to request the initiation of a sensing task. In other optional embodiments, the third request may also be called a sensing request, a sensing service request, a sensing service request, or a request to initiate a sensing task, in order to notify or request a third network element to initiate a sensing service process.

[0095] In this embodiment, the third request also includes relevant information about the second network element, so that the sensing device can establish a link or tunnel between the second network elements based on the relevant information of the second network element.

[0096] In this embodiment, the response to the third request may further include relevant information about the sensing device. This relevant information is used to establish a link or tunnel with the sensing device. As one implementation, the relevant information may specifically be tunnel information, port information, RAN user plane address, interface information, IP address information, etc., of the sensing device. For example, tunnel information may be TEID. This embodiment does not limit the type of relevant information about the sensing device; any information capable of establishing a link or tunnel with the sensing device is within the scope of protection of this embodiment.

[0097] In some alternative embodiments, the response to the third request includes information about the sensing device that failed to initiate the sensing task; the first network element generates or updates the first set based on the information of the sensing device corresponding to the sensing task, including: the first network element updates the first set based on the information of the sensing device that failed to initiate the sensing task.

[0098] In this embodiment, the response to the third request includes information about the sensing devices that failed to initiate the sensing task. Specifically, the first network element sends a third request to the sensing devices to request the initiation of the sensing task. This third request can be sent to multiple sensing devices, and upon receiving the third request, the multiple sensing devices initiate and execute the sensing task. During the process of multiple sensing devices initiating and executing the sensing task, the following situations exist: all sensing devices successfully initiate and execute the sensing task, some sensing devices successfully initiate and execute the sensing task (in which case some sensing devices fail to initiate and execute the sensing task), and all sensing devices fail to initiate and execute the sensing task. In the second and third situations mentioned above, there are sensing devices that failed to initiate the sensing task, and the response to the third request returned by the sensing devices can carry information about the sensing devices that failed to initiate the sensing task. The first network element can then update the first set based on the information about the sensing devices that failed to initiate the sensing task, specifically by deleting the information about the sensing devices that failed to initiate the sensing task from the original first set or deleting the correspondence related to the information about the sensing devices that failed to initiate the sensing task. Furthermore, the first network element sends the updated first set to the second network element.

[0099] Thus, the first network element in the control plane supports generating a first set of correspondences between sensing tasks and sensing devices, and supports operations such as updating (merging, deleting) the first set, thereby realizing the management of sensing tasks and corresponding sensing devices by the first network element; the first network element sends the first set to the second network element in the user plane, so that the second network element performs association processing on the sensing data and the sensing tasks corresponding to the sensing devices based on the first set, thereby realizing the association processing of single sensing data reported by the sensing devices with sensing tasks.

[0100] In some alternative embodiments, updating the first set includes: when multiple sensing tasks correspond to sensing devices that are the same or partially the same, the first network element updates the first set based on the same or partially the same sensing devices.

[0101] In some alternative embodiments, the first set includes at least one set of sensing devices and a correspondence between multiple sensing tasks.

[0102] This embodiment can be applied to the following scenario: multiple application functions (AFs) initiate sensing task requests, and the sensing tasks requested by multiple AFs will be anchored to the same sensing device in some areas.

[0103] In the above scenario, where multiple sensing tasks correspond to sensing devices that are identical or partially identical, for example, a first network element receives first requests from multiple access points (AFs), each carrying information related to a corresponding sensing task. After the first network element selects the corresponding sensing device based on this information, if multiple sensing tasks correspond to identical or partially identical sensing devices, the first network element updates the first set based on these identical or partially identical sensing devices. Then, the first network element sends the updated first set to the second network element.

[0104] Taking the example of two sensing tasks initiated by different AFs corresponding to sensing devices that are identical or partially identical, the first set can include one or more sets of correspondences in the following form: index, sensing task identifier (ID), and sensing device information (such as the identifier of the sensing device). Then the first set can be represented as:

[0105] Index 1 + Perception Task ID (Perception Task ID of AF1 + Perception Task ID of AF2) + Perception Device (The perception devices used in conjunction with the perception tasks of AF1 and AF2).

[0106] Index 2 + Perception Task ID (AF1's perception task ID) + Perception Device (only the perception device corresponding to AF1's perception task);

[0107] Index 3 + Perception Task ID (AF2's perception task ID) + Perception Device (only the perception device corresponding to AF2's perception task).

[0108] As another example, the first set may include one or more sets of correspondences in the form of: information about the sensing device (such as the identifier of the sensing device) and the identification of the sensing task (ID). Then the first set can be represented as:

[0109] Sensing device 1 + sensing task ID (sensing task ID of AF1 + sensing task ID of AF2);

[0110] Sensing device 2 + sensing task ID (sensing task ID of AF1);

[0111] Sensing device 3 + sensing task ID (sensing task ID of AF2).

[0112] Optionally, the correspondences in the first set mentioned above may also carry information about the second network element (such as the identifier of the second network element).

[0113] Thus, the first network element in the control plane supports generating a first set of correspondences between multiple sensing tasks and sensing devices, and supports operations such as updating (merging, deleting) the first set, thereby realizing the management of multiple sensing tasks and corresponding sensing devices by the first network element; the first network element sends the first set to the second network element in the user plane, so that the second network element performs association processing on the sensing data and multiple sensing tasks corresponding to the sensing devices based on the first set, thereby realizing the association processing of a single sensing data reported by the sensing device with multiple sensing tasks.

[0114] Based on the above embodiments, this invention provides a method for associative processing of perception tasks. Figure 3 This is a flowchart illustrating the association processing method for perception tasks according to an embodiment of the present invention. Figure 2 ;like Figure 3 As shown, the method includes:

[0115] Step 201: The second network element receives the first set sent by the first network element, the first set including at least one set of correspondences between sensing tasks and sensing devices;

[0116] Step 202: The second network element receives sensing data from the sensing device and associates the sensing data with the sensing task corresponding to the sensing device based on the first set.

[0117] In this embodiment, the first network element is a control plane network element with sensing capabilities, and the second network element is a data plane network element with sensing capabilities. For example, the first network element can be a sensing-control plane (SF-C), and the second network element can be a sensing-user plane (SF-U), meaning the combination of the first and second network elements is responsible for sensing service processing. In some optional embodiments, the first and second network elements can be combined, meaning the first and second network elements are configured as a partial functional combination within the network element device, responsible for sensing service processing. In other optional embodiments, the first and second network elements can be deployed separately, meaning the first network element can be deployed in one network element device, and the second network element can be deployed in another network element device.

[0118] In this embodiment, the first set includes at least one set of correspondences between sensing devices and sensing tasks. For example, the first set may also be referred to as a first list, a first set of sensing task relationships, a first list of sensing task relationships, etc., containing correspondences, each of which includes a sensing device and a corresponding sensing task. The first set is used to indicate the correspondence between sensing tasks and sensing devices.

[0119] As one example, the first set may include one or more sets of correspondences in the form of: index, sensing task identifier (ID), and sensing device information (such as the identifier of the sensing device). As another example, the first set may include one or more sets of correspondences in the form of: sensing device information (such as the identifier of the sensing device) and sensing task identifier (ID).

[0120] In this embodiment, the first network element sends a first set to the second network element, so that the second network element can associate the received sensing data with the sensing tasks corresponding to the sensing devices based on the first set. Thus, the first network element in the control plane supports generating a first set of correspondences between single or multiple sensing tasks and sensing devices, and supports operations such as generating and updating (merging, deleting) the first set, thereby realizing the management of sensing tasks and corresponding sensing devices by the first network element. The first network element then sends the first set to the second network element in the user plane, enabling the second network element to perform association processing on the sensing data and the sensing tasks corresponding to the sensing devices based on the first set, thus realizing the association processing of single sensing data reported by the sensing devices with sensing tasks.

[0121] In some alternative embodiments, the first set includes at least one set of correspondences between sensing devices, sensing tasks, and second network elements.

[0122] In this embodiment, after the first network element selects the second network element, it can add the information of the second network element to the first set and the corresponding relationship of the sensing device associated with the second network element according to the correspondence between the sensing device and the second network element. That is, the first set may include at least one set of correspondence between sensing devices, sensing tasks and the second network element.

[0123] For example, the first set may include one or more sets of correspondences in the form of: index, sensing task identifier (ID), sensing device information (such as the identifier of the sensing device), and second network element information (such as the identifier of the second network element). As another example, the first set may include one or more sets of correspondences in the form of: sensing device information (such as the identifier of the sensing device), sensing task identifier (ID), and second network element information (such as the identifier of the second network element).

[0124] In this way, the first network element of the control plane can generate a first set according to the correspondence between the sensing task, the sensing device and the second network element, and send the first set to the second network element. This enables the first network element to manage the sensing task and the corresponding sensing device, and enables the second network element of the user plane to determine the sensing task or sensing data within its operating range based on the first set. Then, it can perform association processing on the sensing data and the sensing task corresponding to the sensing device, thus realizing the association processing of the single sensing data reported by the sensing device with the sensing task.

[0125] In some alternative embodiments, where the first set includes at least one set of correspondences between sensing devices, sensing tasks, and second network elements, the first set is a first set associated with the second network element.

[0126] In this embodiment, the first network element can sort out the correspondence relationship containing the information of the second network element based on the information of the second network element, and then generate a first set based on the correspondence relationship containing the information of the second network element. In this case, the correspondence relationship included in the first set is a correspondence relationship associated with the second network element.

[0127] In this way, the first network element in the control plane can sort out the sensing tasks and / or sensing devices belonging to the operation scope of the second network element according to the correspondence between the sensing tasks, sensing devices and the second network element, thereby generating a first set corresponding to the second network element, and sending the first set to the second network element. This realizes the management of sensing tasks and corresponding sensing devices by the first network element, and enables the second network element in the user plane to perform association processing on sensing data and sensing tasks corresponding to sensing devices based on the first set, thus realizing the association processing of single sensing data reported by sensing devices with sensing tasks.

[0128] In some optional embodiments, the second network element receives a first set sent by the first network element, including: the second network element receiving a second request sent by the first network element, the second request being used to initiate a sensing task, the second request including the first set generated by the first network element.

[0129] In this embodiment, the second request is used to request the initiation of a sensing task. In other optional embodiments, the second request may also be called a sensing request, a sensing service request, a sensing service request, or a request to initiate a sensing task, in order to notify or request the second network element to initiate a sensing service process.

[0130] In this embodiment, the second request includes the first set, so that the second network element can associate the received sensing data with the sensing task corresponding to the corresponding sensing device based on the first set. In other optional embodiments, the second request may also include at least a portion of the sensing task-related information.

[0131] In some optional embodiments, the method further includes: the second network element sending a second response corresponding to the second request to the first network element, the second response including relevant information of the second network element. The relevant information of the second network element is used to establish a link, bearer, or tunnel with the second network element. As one implementation, the relevant information of the second network element may specifically be tunnel information, port information, IP address information, interface information, etc. of the second network element. For example, the tunnel information may be, for instance, a TEID. This embodiment does not limit the type of relevant information of the second network element; any information capable of establishing a link or tunnel with the second network element is within the scope of protection of this embodiment.

[0132] In some optional embodiments, the second network element receives a first set sent by the first network element, including: the second network element receiving an updated first set sent by the first network element, wherein the first set is updated by the first network element based on information of sensing devices that failed to start sensing tasks, or, in the case where there are identical or partially identical sensing devices corresponding to multiple sensing tasks, the first set is updated by the first network element based on the identical or partially identical sensing devices.

[0133] In this embodiment, as one implementation method, when the first network element receives information from the sensing device indicating that a sensing device failed to initiate a sensing task, the first network element can update the first set based on this information. Specifically, this involves deleting the information of the sensing device that failed to initiate the sensing task from the original first set, or deleting the corresponding relationships related to this information. Then, the first network element sends the updated first set to the second network element.

[0134] Thus, the first network element in the control plane supports generating a first set of correspondences between sensing tasks and sensing devices, and supports operations such as updating (merging, deleting) the first set, thereby realizing the management of sensing tasks and corresponding sensing devices by the first network element; the first network element sends the first set to the second network element in the user plane, so that the second network element performs association processing on the sensing data and the sensing tasks corresponding to the sensing devices based on the first set, thereby realizing the association processing of single sensing data reported by the sensing devices with sensing tasks.

[0135] As another implementation, in a scenario where multiple AFs initiate sensing task requests, and the sensing tasks requested by the multiple AFs are anchored to the same sensing device in some areas—that is, when the sensing devices corresponding to multiple sensing tasks are the same or partially the same—for example, a first network element receives first requests from multiple AFs, each carrying relevant sensing task information; then, after the first network element selects the corresponding sensing device based on the relevant sensing task information, if the sensing devices corresponding to multiple sensing tasks are the same or partially the same, the first network element updates the first set based on the same or partially the same sensing devices. Subsequently, the first network element sends the updated first set to the second network element.

[0136] In some alternative embodiments, the first set includes at least one set of sensing devices and a correspondence between multiple sensing tasks.

[0137] Taking the example of two sensing tasks initiated by different AFs corresponding to sensing devices that are identical or partially identical, the first set can include one or more sets of correspondences in the following form: index, sensing task identifier (ID), and sensing device information (such as the identifier of the sensing device). Then the first set can be represented as:

[0138] Index 1 + Perception Task ID (Perception Task ID of AF1 + Perception Task ID of AF2) + Perception Device (The perception devices used in conjunction with the perception tasks of AF1 and AF2).

[0139] Index 2 + Perception Task ID (AF1's perception task ID) + Perception Device (only the perception device corresponding to AF1's perception task);

[0140] Index 3 + Perception Task ID (AF2's perception task ID) + Perception Device (only the perception device corresponding to AF2's perception task).

[0141] As another example, the first set may include one or more sets of correspondences in the form of: information about the sensing device (such as the identifier of the sensing device) and the identification of the sensing task (ID). Then the first set can be represented as:

[0142] Sensing device 1 + sensing task ID (sensing task ID of AF1 + sensing task ID of AF2);

[0143] Sensing device 2 + sensing task ID (sensing task ID of AF1);

[0144] Sensing device 3 + sensing task ID (sensing task ID of AF2).

[0145] Optionally, the correspondences in the first set mentioned above may also carry information about the second network element (such as the identifier of the second network element).

[0146] Thus, the first network element in the control plane supports generating a first set of correspondences between multiple sensing tasks and sensing devices, and supports operations such as updating (merging, deleting) the first set, thereby realizing the management of multiple sensing tasks and corresponding sensing devices by the first network element; the first network element sends the first set to the second network element in the user plane, so that the second network element performs association processing on the sensing data and multiple sensing tasks corresponding to the sensing devices based on the first set, thereby realizing the association processing of a single sensing data reported by the sensing device with multiple sensing tasks.

[0147] In some alternative embodiments, associating the sensing data with the sensing task corresponding to the sensing device based on the first set includes: the second network element associating the sensing data with multiple sensing tasks corresponding to the sensing device based on the first set.

[0148] In some optional embodiments, the method further includes: the second network element obtaining multiple sensing results based on the sensing data, and sending each sensing result to the application function corresponding to the corresponding sensing task.

[0149] In this embodiment, sensing devices with a merging relationship only need to upload one sensing data to the second network element. That is, for sensing devices whose sensing tasks overlap with those of multiple AFs, the sensing device can report sensing data only once. After receiving the sensing data, the second network element can determine the corresponding sensing device through the link that received the sensing data, and then search the first set to determine the sensing task corresponding to the sensing device. That is, the sensing data is associated with each sensing task, and then the sensing data is calculated for each sensing task to obtain the sensing result corresponding to each sensing task. The sensing results of each sensing task are then sent to the AF corresponding to each sensing task.

[0150] According to the technical solution of this invention, in a first aspect, a first network element in the control plane supports generating a first set of correspondences between single or multiple sensing tasks and sensing devices, and supports operations such as generating and updating (merging, deleting) the first set; simultaneously, the first network element supports sending the first set to a second network element in the user plane. In a second aspect, the first network element supports triggering update (merging, deleting, etc.) operations on the first set when a sensing task is requested or when a sensing device reports the start status of a sensing task. In a third aspect, the first network element supports saving the correspondences in the first set according to a specific format. In a fourth aspect, the second network element supports receiving the first set and supports transforming correspondences of different dimensions based on the first set, such as the same sensing task corresponding to different sensing devices, or the same sensing device corresponding to different sensing tasks. In a fifth aspect, the second network element supports determining the sensing task corresponding to the sensing data reported by the sensing device based on the first set and performing association processing on the related data. In a sixth aspect, the second network element supports associating a single sensing data reported by the sensing device with multiple sensing tasks.

[0151] The association processing method for perception tasks in this embodiment of the invention will be described below with specific examples.

[0152] Figure 4 This is a schematic diagram of the interaction flow of the perception task association processing method according to an embodiment of the present invention; in this example, the first network element is SF-C and the second network element is SF-U, and the explanation is based on AF1 and AF2 initiating perception task requests respectively. Figure 4 As shown, the method includes:

[0153] Step 301: AF1 sends a SenseTaskStartRequest to NEF, and NEF sends a SenseTaskStartRequest to SF-C.

[0154] Here, the request to start a sensing task sent by AF1 may carry at least one of the following: sensing service identifier (afTaskId), sensing service type, task area, refresh rate, service area, etc.

[0155] When NEF receives a request to initiate a sensing task, it selects SF-C based on the service area and sends the request to SF-C with at least one of the following: sensing service identifier (afTaskId), sensing service type, task area, refresh rate, service area, etc.

[0156] Step 302: SF-C receives the request to start the sensing task, selects the sensing device, selects SF-U, and generates the first set (sensing task relationship list).

[0157] Here, SF-C selects the corresponding sensing device (base station or terminal) based on the mission area information / sensing type it carries; and selects SF-U based on the selected sensing device and service area (such as TAC information).

[0158] In this example, the first set includes at least one correspondence between sensing devices and sensing tasks. The first set is used to indicate the correspondence between sensing tasks and sensing devices on the SF-C and / or SF-U sides, and can be used for merging subsequent sensing tasks.

[0159] For example, the first set may include one or more sets of correspondences in the following form:

[0160] Index, sensing task identifier (ID), and information about the sensing device (such as the identifier of the sensing device);

[0161] Information about the sensing device (such as the identification of the sensing device) and the identification (ID) of the sensing task.

[0162] Optionally, the correspondence in the first set may also include information about the selected SF-U, that is, the first set may include one or more sets of correspondence in the following form:

[0163] Index, sensing task identifier (ID), sensing device information (such as the sensor device identifier), and second network element information (such as the second network element identifier);

[0164] Information of sensing devices (such as the identification of sensing devices), sensing task identification (ID), and information of second network elements (such as the identification of second network elements).

[0165] Step 303: SF-C sends a request to initiate a perception task to the selected SF-U, and the request to initiate a perception task carries the first set.

[0166] The first set may be the first set of information that does not carry SF-U, or the first set may be the first set of information that carries SF-U.

[0167] Optionally, SF-C can also sort out the correspondence with SF-U based on the information of SF-U, and then send the first set to SF-U as the first set associated with SF-U; that is, in this case, the sensing devices in the correspondence carried by the first set received by SF-U are all sensing devices corresponding to or associated with SF-U, or the information of SF-U carried in the first set received by SF-U all refer to SF-U.

[0168] Step 304: SF-U receives the request to start the perception task and returns a response to start the perception task, which carries relevant information about SF-U.

[0169] Here, the relevant information of the SF-U may include at least one of the following: IP address information, TEID information, interface information, tunnel information, etc.

[0170] Step 305: After receiving the response from SF-U, SF-C will send the request to initiate a sensing task to the sensing device (such as a base station), carrying the relevant information of SF-U and the sensing cell information.

[0171] Here, SF-C can send a request to start a sensing task to multiple sensing devices. In this example, we will use SF-C to send a request to start a sensing task to sensing device 1 and sensing device 2 as an example.

[0172] Step 306: The sensing devices (sensing device 1 and sensing device 2) return the response to start the sensing task, carrying the relevant information of the sensing devices.

[0173] Here, the relevant information of the sensing device may include at least one of the following: IP address information, TEID information, RAN user plane address, interface information, tunnel information, etc.

[0174] Optionally, the response to initiate a sensing task may also include information about sensing devices that failed to initiate the sensing task.

[0175] Steps 307-308: If the response to initiate the sensing task also includes information about sensing devices that failed to initiate the sensing task, SF-C updates the first set and sends the updated first set and related information about the sensing devices to SF-U.

[0176] It should be noted that if the response to initiate a sensing task does not include information about sensing devices that failed to initiate the sensing task, SF-C will only send the relevant information of the sensing devices to SF-U.

[0177] Step 309: SF-U returns a response to SF-C.

[0178] In this way, since the sensing device obtains relevant information about the SF-U, and the SF-U also obtains relevant information about the sensing device, the sensing device can establish a link or bearer between the sensing device and the SF-U based on the relevant information about the SF-U, so that the sensing device can send sensing data to the SF-U.

[0179] Step 310: SF-C obtains all task responses and sends a start perception task response (NSF-C_SenseTask_SenseTaskResponse) to NEF. NEF returns the start perception task response (Nnef_SenseTask_SenseTaskResponse) to AF, indicating the result of the perception task start (perception task start failed, perception task partially started successfully, or perception task started successfully).

[0180] Step 311: The sensing device starts the sensing task, generates sensing data, and establishes a sensing data transmission link with SF-U to transmit the sensing data.

[0181] Step 312: SF-U receives the sensing data, sorts the sensing data according to the first set, and calculates the sensing results.

[0182] Currently, since the first set only includes the relevant correspondence of one sensing task, SF-U can calculate the sensing results based on the received sensing data.

[0183] Here, SF-U can determine the sensing device corresponding to the uploaded sensing data based on the sensing data link, and at the same time, it can clarify the correspondence between sensing data and sensing tasks by sorting out the matching relationship between sensing devices and sensing task IDs based on the first set.

[0184] Step 313: AF2 sends a SenseTaskStartRequest to NEF, and NEF sends a SenseTaskStartRequest to SF-C.

[0185] Similar to step 301, the request to start a sensing task sent by AF2 may carry at least one of the following: sensing service identifier (afTaskId), sensing service type, task area, refresh rate, service area, etc.

[0186] When NEF receives a request to initiate a sensing task, it selects SF-C based on the service area and sends the request to SF-C with at least one of the following: sensing service identifier (afTaskId), sensing service type, task area, refresh rate, service area, etc.

[0187] Step 314: SF-C receives the request to start the sensing task, selects the sensing device, selects SF-U, merges the sensing tasks, and updates the first set.

[0188] Here, the first set includes at least one set of sensing devices and the correspondence between multiple sensing tasks.

[0189] For example, the first set may include one or more sets of correspondences in the following form:

[0190] Index, sensing task identifier (ID), and information about the sensing device (such as the identifier of the sensing device);

[0191] Information about the sensing device (such as the identification of the sensing device) and the identification (ID) of the sensing task.

[0192] Taking the first representation method mentioned above as an example, the first set can be represented as:

[0193] Index 1 + Perception Task ID (Perception Task ID of AF1 + Perception Task ID of AF2) + Perception Device (The perception devices used in conjunction with the perception tasks of AF1 and AF2).

[0194] Index 2 + Perception Task ID (AF1's perception task ID) + Perception Device (only the perception device corresponding to AF1's perception task);

[0195] Index 3 + Perception Task ID (AF2's perception task ID) + Perception Device (only the perception device corresponding to AF2's perception task).

[0196] Taking the second representation method above as an example, the first set can be represented as: sensing device 1 + sensing task ID (sensing task ID of AF1 + sensing task ID of AF2);

[0197] Sensing device 2 + sensing task ID (sensing task ID of AF1);

[0198] Sensing device 3 + sensing task ID (sensing task ID of AF2).

[0199] Optionally, the correspondences in the first set mentioned above may also carry SF-U information (such as the SF-U identifier).

[0200] Step 315: SF-C sends a Start Sensing Task Request to the selected SF-U, carrying the updated first set in the Start Sensing Task Request.

[0201] Step 316: The SF-U receives the request to start the sensing task and returns relevant information about the SF-U for data transmission.

[0202] Here, if the first set includes the SF-U selected in step 315, then step 316 may not be executed.

[0203] Subsequent sensing task initiation and sensing data reporting follow steps 305-311.

[0204] Here, sensing devices with a merging relationship only need to upload one set of sensing data to the SF-U. That is, for sensing devices whose sensing tasks for AF1 and AF2 overlap, the sensing device can report sensing data only once. After receiving the sensing data, the SF-U can determine the corresponding sensing device through the link that received the sensing data, and then search the first set to determine the sensing tasks for AF1 and AF2 corresponding to the sensing device. In other words, the sensing data is associated with the sensing tasks for AF1 and AF2. Then, the sensing data is calculated for the sensing tasks for AF1 and AF2 respectively to obtain the sensing results corresponding to the sensing tasks for AF1 and AF2. The sensing results for the sensing tasks for AF1 are sent to AF1, and the sensing results for the sensing tasks for AF2 are sent to AF2.

[0205] Based on the above embodiments, this invention also provides a sensing task association processing device, which is applied to a first network element.

[0222] This invention also provides an association processing device for sensing tasks, which is applied to a second network element. Figure 6 This is a schematic diagram of the composition structure of the association processing device for the perception task according to an embodiment of the present invention. Figure 2 ;like Figure 6 As shown, the device includes: a second communication unit 21 and a second processing unit 22; wherein,
