It should be noted that, Figure 1 Only at least part of the network elements in the networking architecture of the 5G sensing network are shown, but not used to limit the types and quantities of network elements included in the networking architecture of the 5G sensing network.

[0043] Wherein, the 5G sensing network can have sensing capability, that is, one or more devices with sensing capability, which can perceive the position, distance, speed, etc. of the target object (sensing object) through the transmission and reception of wireless signals, or detect, track, identify, image, etc. the target object, event or environment, etc.

[0044] In an exemplary embodiment, as Figure 2 shown, a processing method of a sensing task is provided, which is applied to Figure 1 a sensing function network element SF in the figure as an example, including the following steps 201 to 203. Wherein:

[0045] Step 201, obtaining the sensing area carried by the sensing task to be processed, and obtaining the current service area of each sensing device; the sensing function network element obtains the current service area of the sensing device based on any one of the sensing device, the location management function network element and the unified data management entity network element.

[0046] Wherein, the sensing task to be processed can be sent by an application function AF to the sensing function network element SF, and the selection of the sensing device for executing the related sensing task and the acquisition of the sensing result of the selected sensing device for executing the sensing task need to be realized through the sensing function network element.

[0047] Wherein, the sensing task can carry a sensing area (sensing range), a sensing event and a sensing duration, etc. The sensing area of the sensing task can be a pre-set two-dimensional area, a three-dimensional area, etc.; the application scenario of the sensing task can include but is not limited to weather, agriculture, traffic, automobile, unmanned aerial vehicle, specific personnel, health and case, etc.; the sensing event of the sensing task can include but is not limited to weather condition, air quality, traffic flow, people flow, target shape contour, action, heartbeat and expression, etc.; the sensing duration of the sensing task can be pre-set based on demand.

[0048] In the case that the sensing device initiates the sensing capability registration to the sensing function network element and the registration is successful, the sensing device is likely to move, and thus the service area corresponding to the sensing device changes after the sensing device moves. The application provides an alternative implementation, in which the sensing function network element acquires the current service area (the latest service area) of each sensing device that has successfully registered with the sensing function network element and has a communication relationship, in the case that the sensing function network element receives a sensing task to be processed each time. The application also provides an alternative implementation, in which the sensing function network element acquires the current service area of each sensing device that has successfully registered with the sensing function network element and has a communication relationship, in real time or based on a preset period, so as to quickly and accurately determine the sensing device that can be used to process the related sensing task in the case that the sensing function network element receives any sensing task.

[0049] In addition, the application provides at least three alternative implementations for the manner in which the sensing function network element acquires the current service area of each sensing device that has successfully registered with the sensing function network element and has a communication relationship. One is that the sensing function network element directly acquires the current service area of each sensing device based on the communication of each sensing device. Two is that the sensing function network element indirectly acquires the current service area of each sensing device based on the communication between the location management function network element (LMF) and the sensing function network element. Three is that the sensing function network element indirectly acquires the current service area of each sensing device based on the communication between the unified data management entity network element (UDM) and the sensing function network element.

[0050] However, the application does not make specific limitations on the triggering manner in which the sensing function network element acquires the current service area of each sensing device through any one of the sensing device, the location management function network element, and the unified data management entity network element, and does not limit the data acquisition manner in which the sensing function network element acquires the current service area of each sensing device through any one of the sensing device, the location management function network element, and the unified data management entity network element.

[0051] In step 202, the target sensing device located in the sensing area is determined based on the sensing area and the current service area of each sensing device.

[0052] For example, the sensing function network element can determine, based on the comparison between the sensing area carried by the sensing task and the current service area of each sensing device in communication with the sensing function network element, that the current service area of some sensing devices has an overlap with the sensing area. In the case that the current service area of the sensing device is located in the sensing area and / or the overlap area between the current service area of the sensing device and the sensing area exceeds a preset threshold, the sensing function network element can determine the related sensing device as the target sensing device.

[0053] In step 203, the sensing task is sent to each target sensing device; the sensing task is used to instruct the target sensing device to perform sensing measurement on the sensing object in the sensing area.

[0054] For example, after determining the target sensing device that is adapted to the sensing area of the sensing task, the sensing function network element can send the sensing task to each target sensing device, so that each target sensing device performs sensing measurement on the sensing object in the current service area based on the requirements such as sensing event and sensing duration included in the sensing task, so that each target sensing device obtains relevant measurement data. Each target sensing device can further report the measurement data obtained by performing sensing measurement on the sensing object in the current service area to the sensing function network element, so that the sensing function network element can obtain all measurement data corresponding to the to-be-processed sensing task, and then obtain the sensing result corresponding to the to-be-processed sensing task by integrating all the measurement data; then the sensing function network element can return the sensing result corresponding to the sensing task to the application function AF that sends the to-be-processed sensing task, so that the application function AF realizes the execution of the sensing task through the sensing function network element.

[0055] The above-mentioned processing method of the sensing task applied to the sensing function network element, by obtaining the sensing area carried by the to-be-processed sensing task and the current service area of each sensing device, so that the sensing function network element can know the overlap between the current service area of each sensing device and the sensing area of the sensing task, to avoid the situation that the service area after the sensing device moves does not match the sensing area after the sensing device initially registers; the sensing function network element obtains the current service area of the sensing device based on any one of the sensing device, the location management function network element and the unified data management entity network element, so that the sensing function network element can determine the current service area of the sensing device based on multiple different paths, which is beneficial to ensure the smoothness, stability and diversity of the sensing function network element to obtain the current service area of the relevant sensing device; based on the sensing area and the current service area of each sensing device, the target sensing device located in the sensing area is determined, to realize the selection of the appropriate sensing device adapted to the sensing task; the sensing task is sent to each target sensing device; the sensing task is used to instruct the target sensing device to perform sensing measurement on the sensing object in the sensing area; so that the sensing function network element can obtain the sensing result corresponding to the sensing task through the execution of the target sensing device on the sensing task.

[0056] In an exemplary embodiment, obtaining the current service area of each sensing device comprises: broadcasting a service area acquisition request to the sensing device, and receiving the current service area reported by each sensing device based on the service area acquisition request; and / or, in the case that the current service area of any sensing device changes, receiving the updated current service area reported by the sensing device.

[0057] The service area acquisition request is broadcast to the sensing devices, specifically, the sensing function network element sends the service area acquisition request to each sensing device that has successfully registered with the sensing function network element and has a communication relationship.

[0058] In an embodiment, after receiving the service area acquisition request, each sensing device can immediately report its corresponding current service area to the sensing function network element, so that the sensing function network element can accurately learn the current service area (the most recent service area) of the relevant sensing device.

[0059] In an embodiment, after receiving the service area acquisition request, each sensing device compares its corresponding current service area with the service area reported to the sensing function network element last time. If the current service area is different from the last reported service area, the sensing device reports its corresponding current service area to the sensing function network element again, so that the sensing function network element can accurately learn the current service area (the most recent service area) of the relevant sensing device. If the current service area is the same as the last reported service area, the sensing device does not need to report its current service area to the sensing function network element again, thereby avoiding repetitive data interaction and reducing the amount of data interaction between the sensing function network element and the plurality of sensing devices.

[0060] In another embodiment, each sensing device monitors its service area in real time. If the service area changes, the sensing device actively reports its current service area (the latest service area) to the sensing function network element, so that the sensing function network element can learn the current service area of each sensing device in a timely manner.

[0061] By way of example, to illustrate how the sensing function network element acquires the current service area of each sensing device, the present application provides an alternative embodiment in which the sensing function network element actively broadcasts a service area acquisition request to each sensing device, and receives the current service area of at least part of the sensing devices reported based on the service area acquisition request. If a sensing device does not receive the service area acquisition request, it can also actively transmit its corresponding current service area to the sensing function network element if it detects a change in its service area, so that the sensing function network element can receive the updated current service area reported by the sensing device. In addition, each sensing device can be configured to actively transmit its corresponding current service area to the sensing function network element if it actively detects a change in the current service area.

[0062] In this embodiment, the perception function network element directly interacts with each perception device in communication to directly acquire the current service area of each perception device, which is conducive to simplifying the data transmission path of the perception function network element for acquiring the current service area of each perception device, and is conducive to guaranteeing the accuracy of the acquired current service area of each perception device.

[0063] In one exemplary embodiment, acquiring the current service area of each perception device includes: sending a subscription request for each perception device to a location management function network element; the device identifier of each perception device is included in the subscription request; and receiving an updated current service area sent by the location management function network element based on the subscription request in the case that the current service area of at least one perception device changes.

[0064] The location management function network element is an LMF in the networking architecture of the 5G perception network.

[0065] Exemplarily, for how the perception function network element acquires the current service area of each perception device in communication, the application provides an alternative implementation that the perception function network element actively sends a subscription request for each perception device in communication to the location management function network element in the perception network, and the subscription request is specifically a subscription request for the service area of each perception device in communication; the subscription request sent by the perception function network element to the location management function network element can include the device identifier of each perception device in communication, or the device identifier of each perception device whose current service area it wants to acquire, so that the location management function network element can know which current service area of which perception device the perception function network element specifically wants to acquire.

[0066] In one embodiment, when the location management function network element receives the subscription request for the service area of the perception device sent by the perception function network element, it can acquire the current service area of each perception device pointed to by the device identifier based on the device identifier of the perception device carried in the subscription request, and return the current service area of the related perception device to the perception function network element, so that the perception function network element can receive the updated current service area reported by the perception device.

[0067] Another embodiment is that when the location management function network element receives the subscription request for the service area of the perception device sent by the perception function network element, it can choose to acquire the current service area of all perception devices pointed to by the device identifier in the subscription request and upload it to the perception function network element, so that the perception function network element can receive the current service area of all perception devices pointed to by the device identifier.

[0068] In another embodiment, when the location management function network element receives the subscription request for the service area of the sensing device sent by the sensing function network element, the current service area of all sensing devices to which the device identifier in the subscription request points and the last service area transmitted by each sensing device to the sensing function network element can be compared. Only when the current service area of the sensing device changes compared with the last service area, the current service area of the sensing device is uploaded to the sensing function network element. If the current service area of one or more sensing devices does not change compared with the last service area, the repeated service area is not transmitted to the sensing function network element, so as to avoid the repetition of data interaction and reduce the number of data interaction between the sensing function network element and the location management function network element.

[0069] In the embodiment, the sensing function network element sends a subscription request for each sensing device to the location management function network element, and carries the device identifier of each sensing device to be acquired in the subscription request, so that the location management function network element can know which current service area of the sensing device the sensing function network element wants to acquire. Then, the sensing function network element receives the updated current service area sent by the location management function network element based on the subscription request when the current service area of at least one sensing device changes, to obtain the current service area of the related sensing device.

[0070] Obviously, the sensing function network element can reduce the amount of data interaction required to be transmitted by the sensing function network element in the process of acquiring the current service area of each sensing device by acquiring the current service area of each sensing device through the location management function network element.

[0071] In an exemplary embodiment, acquiring the current service area of each sensing device includes: sending a query request for each sensing device to a unified data management entity network element; the query request includes the device identifier of each sensing device; and receiving the current service area of the sensing device sent by the unified data management entity network element based on the query request.

[0072] The unified data management entity network element is a UDM in the networking architecture of the 5G sensing network.

[0073] Exemplarily, in order to acquire the current service area of each sensing device in communication with the sensing function network element, the application provides an alternative implementation that the sensing function network element sends a query request for each sensing device to the unified data management entity network element, and the query request is specifically a query request for the service area of each sensing device in communication; the query request sent by the sensing function network element to the unified data management entity network element can include the device identifier of each sensing device in communication, or the device identifier of each sensing device for which the sensing function network element wants to acquire the current service area, so that the unified data management entity network element can know which current service area of which sensing device the sensing function network element wants to acquire.

[0074] In an embodiment, when the unified data management entity network element receives the query request, it acquires the current service area of each sensing device in communication, and returns the current service area of each sensing device to the sensing function network element, so that the sensing function network element can acquire the current service area of the relevant sensing device based on the unified data management entity network element.

[0075] In the embodiment, the sensing function network element sends a query request for each sensing device to the unified data management entity network element, and carries the device identifier of each sensing device to be acquired in the query request, so that the unified data management entity network element can know which current service area of which sensing device the sensing function network element wants to acquire; then, the sensing function network element receives the current service area sent by the unified data management entity network element based on the query request, to obtain the current service area of the relevant sensing device.

[0076] Obviously, the sensing function network element acquires the current service area of each sensing device by means of the unified data management entity network element, which can reduce the amount of data interaction required to be transmitted by the sensing function network element in the process of acquiring the current service area of each sensing device.

[0077] In an exemplary embodiment, the method for processing the sensing task provided by the application further includes: receiving the updated current service area sent by the unified data management entity network element based on the query request, in the case that the current service area of at least one sensing device changes.

[0078] In one embodiment, when the unified data management entity network element receives a query request for a service area of a sensing device sent by the sensing function network element, the current service area of all sensing devices pointed to by the device identifier in the query request and the last service area transmitted by each sensing device to the sensing function network element can be compared. Only when the current service area of the sensing device is changed compared with the last service area, the current service area of the sensing device is uploaded to the sensing function network element. If the current service area of one or more sensing devices is not changed compared with the last service area, the repeated service area is not transmitted to the sensing function network element, thereby avoiding the repetition of data interaction and reducing the amount of data interaction between the sensing function network element and the unified data management entity network element.

[0079] In the embodiment, the sensing function network element sends a query request for each sensing device to the unified data management entity network element, and carries the device identifier of each sensing device to be acquired in the query request, so that the unified data management entity network element can know which current service area of the sensing device is acquired by the sensing function network element. Then, the sensing function network element receives the updated current service area sent by the unified data management entity network element based on the query request, so as to obtain the current service area of the related sensing device.

[0080] The sensing function network element in the embodiment does not need to directly interact with each sensing device, and can acquire the current service area of each sensing device. The sensing function network element can reduce the amount of data interaction required to be transmitted by the sensing function network element in the process of acquiring the current service area of each sensing device.

[0081] In one exemplary embodiment, the method for processing the sensing task provided by the application further comprises: when receiving the sensing capability registration request sent by any sensing device, acquiring the initial service information of the sensing device carried by the sensing capability registration request, and storing the initial service information of each sensing device; wherein the initial service information includes the initial service area of the sensing device, and the device identifier and the sensing capability; when receiving the updated current service area of at least one sensing device, updating the stored current service area of the related sensing device.

[0082] The sensing device UE with sensing capability initiates sensing capability registration to the sensing function network element SF, and reports its sensing capability, device identifier UE ID (UE Identity document), initial service area (current service cell), and the like. The sensing function network element stores the received information locally.

[0083] Exemplarily, in the case that the sensing device with sensing capability initiatively initiates the sensing capability registration to the sensing function network element, the sensing function network element will acquire the initial service information of the sensing device carried in the sensing capability registration request upon receiving the sensing capability registration request sent by any sensing device, specifically including acquiring the initial service area of each sensing device, and acquiring at least one of the device identifier and the sensing capability; further, the sensing function network element will store the initial service information of each sensing device received; so as to facilitate the subsequent acquisition of the initial service information of each sensing device and the current service information (at least including the current service area) after the initial service information is changed by the sensing function network element, so as to facilitate the sensing function network element to select a suitable sensing device to process the related sensing task upon receiving the sensing task to be processed.

[0084] Exemplarily, since the sensing device will displace after completing the registration to the sensing function network element, therefore, the service area of each sensing device stored by the sensing function network element also needs to be updated and stored in time based on the actual displacement of the sensing device, so as to update the current service area of each sensing device, so as to guarantee that the sensing function network element can select a more suitable sensing device to process the related sensing task upon receiving the new sensing task to be processed.

[0085] Therefore, the sensing function network element will update and store the current service area of the related sensing device upon receiving the current service area of any sensing device updated, so as to realize the update of the service area of each sensing device stored.

[0086] In one exemplary embodiment, the location management function network element can acquire the service area acquisition request corresponding to each sensing device based on the device identifier of each sensing device carried in the subscription request upon receiving the subscription request sent by the sensing function network element for each sensing device, and further send the service area acquisition request for each sensing device to the corresponding each sensing device, so that each sensing device reports its current service area to the location management function network element upon receiving the service area acquisition request.

[0087] In one exemplary embodiment, the unified data management entity network element can acquire the service area acquisition request corresponding to each sensing device based on the device identifier of each sensing device carried in the query request upon receiving the query request sent by the sensing function network element for each sensing device, and further send the service area acquisition request for each sensing device to the corresponding each sensing device, so that each sensing device reports its current service area to the unified data management entity network element upon receiving the service area acquisition request.

[0088] To sum up, the method for processing a perception task provided in the application involves a way of selecting a perception device, specifically, a sensing function network element SF can acquire a service cell (a current service area) of a perception device UE in real time, and then select a perception device UE under a perception area as a target perception device according to the perception area carried by the perception task.

[0089] In the method for processing a perception task provided in the application, the sensing function network element SF acquires service cell information (service information) of the perception device UE in the following three ways:

[0090] The first way is that the perception device UE reports the service cell to the sensing function network element SF, and when the service cell changes, actively reports new service cell information to the sensing function network element SF.

[0091] The second way is that the sensing function network element SF subscribes to location information of the perception device UE from a location management function network element LMF, and when the service cell of the perception device UE changes, the location management function network element LMF updates the current service cell of the perception device UE whose service cell has changed to the sensing function network element SF.

[0092] The third way is that the sensing function network element SF queries service cell information of each perception device UE from a unified data management entity network element UDM.

[0093] Further, the sensing function network element SF screens a perception device UE under a perception area as a target perception device according to the perception area of the perception task and the service cell information of the perception device.

[0094] Exemplarily, please refer to Figure 3 , Figure 3 The method for processing a perception task in which the sensing function network element directly interacts with the perception device is shown, which includes steps 301-308, wherein:

[0095] Step 301: The perception device UE with sensing capability initiates sensing capability registration to the sensing function network element SF, and reports its own sensing capability, device identifier UE ID, current service cell (initial service area), and the like. The sensing function network element SF stores the received information locally.

[0096] Step 302: After the perception device UE completes registration, the sensing function network element SF requests service cell information from the perception device UE, and the message is used to request the perception device UE to update its own service cell in real time. The requested information type is NCI (NR Cell Identity, which is a global identifier used to uniquely identify an NR cell in a 5G network; the full name of NR is New Radio, which is the wireless access technology standard of 5G) of the service cell, and the reporting trigger condition is service cell change.

[0097] Step 303, after receiving the request, the sensing device UE reports the service cell information NCI to the sensing function network element SF when the service cell of the sensing device UE changes. After receiving the report, the sensing function network element SF updates the service cell information corresponding to the device identifier UE ID stored locally.

[0098] Step 304, the application function AF sends a start sensing task request to the sensing function network element SF.

[0099] Step 305, after receiving the sensing task request, the sensing function network element SF selects the sensing device in the sensing area according to the sensing area in the request and the service cell information of the sensing device stored locally.

[0100] Step 306, the sensing function network element SF sends the sensing task request to the selected sensing device.

[0101] Step 307, the sensing device performs corresponding sensing measurement and reports the measurement data (sensing data).

[0102] Step 308, the sensing function network element SF processes the sensing data and returns the sensing result to the application function AF.

[0103] Exemplarily, please refer to Figure 4 , Figure 4 The sensing function network element based on the location management function network element and the processing method of the sensing task interacting with the sensing device is shown, including steps 401-408, wherein:

[0104] Step 401, the sensing device UE with sensing capability initiates sensing capability registration to the sensing function network element SF, and reports its own sensing capability, device identifier UE ID, current service cell and other information. The sensing function network element SF stores the received information locally.

[0105] Step 402, after the sensing device UE completes the registration, the sensing function network element SF sends a positioning request to the location management function network element LMF to subscribe to the service cell information of the sensing device. The device identifier UE ID of the sensing device is carried in the request, the information type of the request is NCI of the service cell, and the trigger condition of the report is the change of the service cell.

[0106] Step 403, after receiving the request, the location management function network element LMF periodically requests the serving cell information of the sensing device UE. According to the existing positioning process, the process can be that the location management function network element LMF obtains from the AMF or obtains from the sensing device UE. When the location management function network element LMF detects that the serving cell of the sensing device changes, it returns the new serving cell information NCI of the sensing device to the sensing function network element SF. After the sensing function network element SF receives the report, it updates the locally stored serving cell information corresponding to the device identifier UE ID of the device.

[0107] Step 404, the application function AF sends a start sensing task request to the sensing function network element SF.

[0108] Step 405, after receiving the sensing task request, the sensing function network element SF selects the sensing device in the sensing area according to the sensing area in the request and the serving cell information of the sensing device stored locally.

[0109] Step 406, the sensing function network element SF issues a sensing task request to the selected sensing device.

[0110] Step 407, the sensing device performs corresponding sensing measurement and reports the measurement data (sensing data).

[0111] Step 408, the sensing function network element SF processes the sensing data and returns the sensing result to the application function AF.

[0112] Exemplarily, please refer to Figure 5 , Figure 5 The sensing function network element based on the unified data management entity network element and the processing method of the sensing task of the sensing device interaction is shown, including steps 501-508, wherein:

[0113] Step 501, the sensing device UE with sensing capability initiates sensing capability registration to the sensing function network element SF, and reports its sensing capability, device identifier UE ID, current serving cell and other information. The sensing function network element SF stores the received information locally.

[0114] Step 502, the application function AF sends a start sensing task request to the sensing function network element SF.

[0115] Step 503, the sensing function network element SF sends a request to the unified data management entity UDM to query the serving cell information of the sensing device UE that has been registered in its management range, and carries the device identifier UE ID of the sensing device in the request. The requested information type is the NCI of the serving cell.

[0116] At step 504, after receiving the request, the unified data management entity UDM returns the serving cell information of the sensing device to the sensing function network element SF. The unified data management entity UDM can query the serving cell information of the sensing device UE from the AMF according to the existing process.

[0117] At step 505, after receiving the sensing task request, the sensing function network element SF selects the sensing device in the sensing area according to the sensing area in the request and the serving cell information of the sensing device stored locally.

[0118] At step 506, the sensing function network element SF sends the sensing task request to the selected sensing device.

[0119] At step 507, the sensing device performs corresponding sensing measurement and reports the measurement data (sensing data).

[0120] At step 508, the sensing function network element SF processes the sensing data and returns the sensing result to the application function AF.
