[0067] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0068] Current 5G sensing network architecture design, such as Figure 1 As shown, the 5G sensing network is an evolution and enhancement of the 5G network in terms of functionality and coverage. It is a key information technology supporting the digital upgrade of industries such as the 3D transformation and cloudification of the Internet, the intelligent interconnection of everything, the integration of communication and sensing, and the flexibility of intelligent manufacturing. The 5G sensing network adds the SF (Sensing Function) network element; the network architecture diagram is attached. Figure 1As shown. SF network elements include SCF (Sensing Control Function) and SPF (Sensing Processing Function) network elements. They collaborate with other network elements to process sensing tasks. SCF and SPF network elements interface with and interact with 5GC network elements such as AMF (Access and Mobility Management Function), NEF (Network Element Function), UDM (Unified Data Management), NWDAF (Network Data Analytics Function), PCF (Policy Control Function), and NRF (Network Repository Function). Sensing control signaling between SCF network elements and RAN / UE can be transmitted directly through the NS2 interface or through the NS11 interface (AMF forwarding). The target data parameters acquired by the RAN (Radio Access Network) are directly transmitted to the SPF network element via the NS3 interface. The SCF and SPF network elements can be co-located or separate. When deployed separately, the SPF network element can be centrally deployed or deployed at the edge.

[0069] The low-altitude economy has been identified as a strategic emerging industry with broad prospects. The integration of the low-altitude economy with 5G (5G mobile communication technology) enables intelligent operation and smart management of the low-altitude economy. In 5G sensing networks, such as... Figure 1 As shown, the SCF network element is responsible for managing the capability registration and task distribution of the Aware RAN (Radio Access Network).

[0070] In existing technologies, if an SCF network element fails (for example, in a disaster environment), the already issued sensing tasks will be interrupted, and new tasks cannot be issued, resulting in the inability to guarantee the continuity of sensing services.

[0071] The perception task execution method provided in this application embodiment can be applied to, for example, Figure 2 In the application environment shown, such as Figure 2 As shown, the target sensing network contains a pair of SCF network elements, namely the main SCF network element (i.e., Figure 2 SCF1 network element and backup SCF network element (i.e.Figure 2 SCF2 network element in FIG. 1), the target perception network contains several perception RANs, Figure 2 Four effective perception RANs (i.e., perception RAN1-perception RAN4) are shown in FIG. 1, the standby SCF network element can acquire the running state of the master SCF network element in the target perception network; and in the case that the running state is a fault state, the standby SCF network element replaces the master SCF network element to execute the perception task according to the synchronized perception task association information between the master SCF network element and the standby SCF network element. The stability and continuity of the perception task processing in the target perception network are improved, and the user satisfaction is improved.

[0072] In one embodiment, Figure 3 is a flow diagram of a perception task execution method according to an embodiment of the present application. The method is applied to the standby SCF network element in FIG. 1. Figure 2 The method includes the following steps:

[0073] S301, acquiring the running state of the master SCF network element in the target perception network.

[0074] The target perception network refers to the perception network in the target area, and the operator can flexibly set the area range of the target area according to its own needs. The master SCF network element refers to the master SCF network element in the target perception network. The standby SCF network element refers to the standby SCF network element in the target perception network.

[0075] As an optional implementation of the embodiment of the present application, the heartbeat packet is periodically (for example, once every 2 seconds) sent to the master SCF network element, so that the master SCF network element feeds back the response packet based on the heartbeat packet. According to the response packet fed back by the master SCF network element, the running state of the master SCF network element in the target perception network is acquired. In this embodiment, according to the response packet fed back by the master SCF network element, one optional implementation of acquiring the running state of the master SCF network element in the target perception network is that the running state of the master SCF network element in the target perception network is acquired according to the packet content of the response packet fed back by the SCF network element; wherein the running state of the master SCF network element is recorded in the response packet. In this embodiment, according to the response packet fed back by the master SCF network element, another optional implementation of acquiring the running state of the master SCF network element in the target perception network is that the running state of the master SCF network element in the target perception network is acquired according to the continuity of the response packet fed back by the master SCF network element, for example, if the response packet fed back by the master SCF network element is not received for a plurality of times, it is determined that the running state of the master SCF network element in the target perception network is a fault state.

[0076] As another optional implementation of the embodiment of the application, the running state subscription request is sent to the master SCF network element in advance, so that the master SCF network element feeds back the running state of the master SCF network element to the backup SCF network element in the case where the network element running state is determined to be the fault state.

[0077] S302, in the case where the running state is the fault state, the perception task is executed instead of the master SCF network element according to the synchronized perception task association information between the master SCF network element and the backup SCF network element.

[0078] The perception task association information refers to information related to the perception task.

[0079] Optionally, the communication link is pre-established between the master SCF network element and the backup SCF network element in the embodiment, and the perception task association information is synchronized in real time or periodically through the communication link. Optionally, the communication link can be a dedicated link (for example, a private line in an IP-RAN (IP Radio Access Network, IP-based wireless access network)) and an incremental synchronization strategy is adopted, that is, only the changed data (such as a newly added task or a changed RAN capability) is transmitted, so as to reduce the bandwidth consumption.

[0080] Optionally, in some embodiments, the perception task association information includes at least one of perception RAN capability information, perception task information, and demand network element subscription information. The perception RAN capability information includes at least one of a perception frequency band, a perception accuracy, a perception refresh rate, a perception area, and a perception type (such as a millimeter wave radar and a camera) of each perception RAN. The perception task information is the perception task information initiated by the demand network element; the perception task information includes at least one of target area information, an execution period, a data reporting frequency, a task priority, and a task identifier. The demand network element subscription information includes at least one of a perception event type (such as mobile object detection and people flow statistics), a notification mode (for example, HTTP (HyperText Transfer Protocol, HyperText Transfer Protocol) push or message queue notification), and a subscription validity period.

[0081] Optionally, the demand in the embodiment is an AF (Application Function, application function) network element and / or an NEF (Network Element Function, network element function) network element.

[0082] As an optional implementation of the embodiment of the application, in the case where the running state is the fault state, the perception task corresponding to the perception task information is executed instead of the master SCF network element according to the perception task information in the synchronized perception task association information between the master SCF network element and the backup SCF network element.

[0083] As another optional implementation of the embodiment of the present application, in the case where the running state is the fault state, the backup SCF network element is taken as the new master SCF network element, and the sensing task information in the synchronized sensing task association information between the master SCF network element and the backup SCF network element is used to replace the master SCF network element to perform the sensing task corresponding to the sensing task information.

[0084] As another optional implementation of the embodiment of the present application, a third sensing task is received from the demand network element. The sensing task information in the synchronized sensing task association information between the master SCF network element and the backup SCF network element and the third sensing task are used to replace the master SCF network element to perform the sensing task. Optionally, in one optional implementation, the demand network element acquires the running state of the master SCF network element and the backup SCF network element based on the form of sending the heartbeat packet. In the case where it is detected that the running state of the master SCF network element is the fault state, the third sensing task is sent to another available SCF network element, i.e., the backup SCF network element. The backup SCF network element uses the sensing task information in the synchronized sensing task association information between the master SCF network element and the backup SCF network element and the third sensing task to replace the master SCF network element to perform the sensing task. Optionally, in another optional implementation, the demand network element acquires the running state of the master SCF network element and the backup SCF network element based on the form of sending the heartbeat packet. In the case where it is detected that the running state of the master SCF network element is the fault state, the backup SCF network element is taken as the new master SCF network element, and the third sensing task is sent to the backup SCF network element. The backup SCF network element uses the sensing task information in the synchronized sensing task association information between the master SCF network element and the backup SCF network element and the third sensing task to replace the master SCF network element to perform the sensing task. In the embodiment, in the case where it is detected that the running state of the master SCF network element is the fault state, the backup SCF network element not only uses the sensing task information in the synchronized sensing task association information to replace the master SCF network element to perform the corresponding sensing task, but also receives the third sensing task from the demand network element and replaces the master SCF network element to perform the corresponding sensing task.

[0085] The sensing task performing method acquires the running state of the master SCF network element in the target sensing network. In the case where the running state is the fault state, the sensing task association information between the master SCF network element and the backup SCF network element is synchronized, and the master SCF network element is replaced to perform the sensing task. In the present application, the structure design of the master SCF network element and the backup SCF network element in the target sensing network enables the sensing task processing to support disaster recovery backup, guarantees the continuity and stability of the sensing task processing, provides technical support for the application of the sensing task in various scenarios, and improves the user satisfaction.

[0086] In one of the embodiments, as shown in Figure 4As shown, an optional implementation of S202, in which the primary SCF network element executes the sensing task according to the sensing task association information synchronized between the primary SCF network element and the backup SCF network element, includes:

[0087] S401, according to the sensing task information in the sensing task association information synchronized between the primary SCF network element and the backup SCF network element, the primary SCF network element sends a target sensing task to the first sensing RAN to make the first sensing RAN execute the target sensing task, and feeds back sensing data to the backup SCF network element.

[0088] The first sensing RAN is a valid sensing RAN in the target sensing network. The valid sensing RAN refers to a sensing RAN that can be normally used in the target sensing network. If all sensing RANs in the target sensing network are valid, all sensing RANs are taken as the first sensing RAN. The target sensing task refers to a sensing task generated by the backup SCF network element based on the sensing task information in the sensing task association information. The sensing data refers to environmental data sensed by the first sensing RAN when executing the target sensing task.

[0089] As an optional implementation of the embodiment of the present application, a target sensing task is generated according to the sensing task information in the sensing task association information synchronized between the primary SCF network element and the backup SCF network element. The target sensing task is sent to the first sensing RAN to make the first sensing RAN execute the target sensing task, and feedback sensing data to the backup SCF network element. The backup SCF network element sends the sensing data fed back by each first sensing RAN to the demand network element.

[0090] As another optional implementation of the embodiment of the present application, in the case of receiving a third sensing task sent by the demand network element, a target sensing task is generated according to the sensing task information in the sensing task association information synchronized between the primary SCF network element and the backup SCF network element. The target sensing task and the third sensing task are sent to the first sensing RAN to make the first sensing RAN execute the target sensing task and the third sensing task, and feedback sensing data to the backup SCF network element. The backup SCF network element sends the sensing data fed back by each first sensing RAN to the demand network element. In the embodiment, the sensing data refers to environmental data sensed by each first sensing RAN when executing the target sensing task and the third sensing task. It should be noted that the order of sending the target sensing task and the third sensing task is not limited in the embodiment.

[0091] S402, receiving the sensing data fed back by the first sensing RAN, and feeding back the sensing data to the demand network element.

[0092] As an optional implementation of the embodiment of the present application, the sensing data fed back by the first sensing RAN is received. The sensing data is fed back to the demand network element according to an aggregation reporting time. The aggregation reporting time refers to an interval time for aggregating and reporting the sensing data sent by each first sensing RAN. For example, the aggregation reporting time is 1 minute, and the backup SCF network element aggregates the sensing data sent by each first sensing RAN within 1 minute and then sends the sensing data to the demand network element.

[0093] As another optional implementation of the embodiment of the present application, the sensing data fed back by the first sensing RAN is received, and the sensing data is directly forwarded to the demand network element. In the embodiment, after receiving the sensing data fed back by the first sensing RAN, the sensing data is directly forwarded to the demand network element.

[0094] Optionally, in the case where the running state is the fault state, the backup SCF network element is used as a new master SCF network element. In the case where the running state is detected to return to the normal state, the master SCF network element is used as a new backup SCF network element. That is, in the case where the registration policy of the first sensing RAN in the target sensing network is the double registration policy, the identity of the master and backup SCF network elements needs to be switched, and only the master SCF network element sends the sensing task to the first sensing RAN.

[0095] It should be noted that in the case where the running state of the master SCF network element is the normal state, the process of executing the sensing task is basically the same as the process of executing the sensing task by the backup SCF network element instead of the master SCF network element.

[0096] In the embodiment, when the master SCF network element fails, the backup SCF network element can directly replace the master SCF network element to send the target sensing task to the first sensing RAN, thereby improving the continuity and timeliness of the sensing task processing.

[0097] In one embodiment, in the case where the registration policy executed by the first sensing RAN in the target sensing network is the double registration policy, before obtaining the running state of the master SCF network element in the target sensing network, as shown in FIG. 5, an optional implementation of a sensing task execution method includes the following steps. Figure 5

[0098] S501, receiving a first sensing capability registration request initiated by a first sensing RAN in a target sensing network based on a double registration policy.

[0099] The double registration policy is a policy in which the first sensing RAN initiates sensing capability registration to a master SCF network element and a backup SCF network element at the same time.

[0100] ​Optionally, the first perception capability registration request in the embodiment further includes at least one of a supported perception capability set, a perception area (for example, can be long, wide, high, or central latitude and longitude in a coordinate system), a perception type (for example, low-altitude scene, water scene, etc.), and a refresh rate.

[0101] Optionally, the first perception RAN has address information of the primary SCF network element and the backup SCF network element stored locally; the address information includes an IP address and a port. The first perception RAN sends a link establishment request message to the primary SCF network element and the backup SCF network element respectively through the address information to complete link establishment with the primary SCF network element and the backup SCF network element, and in the case of successful link establishment, sends the first perception capability registration request to the primary SCF network element and the backup SCF network element respectively through the NS2 interface based on the double registration strategy. The link establishment request message carries information such as PLMN (Public Land Mobile Network), gNodeB ID, etc.

[0102] S502, based on the first perception capability registration request, performing a perception capability registration operation on the first perception RAN.

[0103] Optionally, in the embodiment, based on the first perception capability registration request, the first perception RAN is authenticated and authorized, and after the authentication and authorization pass, the perception capability registration operation is performed on the first perception RAN.

[0104] S503, in the case that the perception capability registration operation indicates that the registration is successful, sending a registration success response message to the first perception RAN.

[0105] It should be noted that the perception capability registration process of the primary SCF network element and the backup SCF network element to the first perception RAN is the same.

[0106] In the embodiment, a first perception capability registration request initiated by a first perception RAN in a target perception network based on a double registration strategy is received; the first perception RAN is a valid perception RAN in the target perception network; the double registration strategy is a strategy that the first perception RAN initiates perception capability registration to the primary SCF network element and the backup SCF network element simultaneously; the first perception capability registration request further includes at least one of a supported perception capability set, a perception area, a perception type, and a refresh rate. Based on the first perception capability registration request, a perception capability registration operation is performed on the first perception RAN. In the case that the perception capability registration operation indicates that the registration is successful, a registration success response message is sent to the first perception RAN. In the embodiment, the perception RAN in the target perception network can perform perception capability registration in the primary SCF network element and the backup SCF network element based on the double registration strategy, which increases the flexibility of the perception capability registration mode, and facilitates the timeliness and continuity of the perception task allocation in the disaster environment.

[0107] On the basis of the above-mentioned embodiments, in the case that the registration strategy executed by the first perception RAN in the target perception network is a single registration strategy, the first perception RAN comprises a second perception RAN and a third perception RAN. The second perception RAN is an effective perception RAN associated with the standby SCF network element, and the third perception RAN is an effective perception RAN associated with the master SCF network element. On this basis, before obtaining the running state of the master SCF network element in the target perception network, the master SCF network element sends a target perception task to the third perception RAN, so that the first perception RAN executes the target perception task, as shown in S401. Figure 6 As shown in S401, in the optional implementation mode in which the target perception task is sent to the third perception RAN by the master SCF network element according to the perception task information in the synchronized perception task association information between the master SCF network element and the standby SCF network element, the optional implementation mode comprises the following steps.

[0108] S601, according to the perception task information in the synchronized perception task association information between the master SCF network element and the standby SCF network element, the target perception task is sent to the second perception RAN and the third perception RAN instead of the master SCF network element, so that the second perception RAN and the third perception RAN execute the target perception task and feed back the perception data to the standby SCF network element.

[0109] Optionally, in the case that the registration strategy executed by the first perception RAN is a single registration strategy, the second perception RAN and the third perception RAN only need to initiate a perception registration request to one of the SCF network elements to register the perception capability. After the registration of the perception capability is completed, the perception RAN capability information is synchronized between the master SCF network element and the standby SCF network element. The perception RAN capability information comprises at least one of the perception frequency band, the perception accuracy, the perception refresh rate, the perception area and the perception type of each perception RAN.

[0110] Optionally, in the case that the running state of the master SCF network element is a fault state and the registration strategy executed by the first perception RAN is a single registration strategy, the corresponding perception task is executed by the standby SCF network element. Optionally, the target perception task is generated according to the perception task information in the synchronized perception task association information between the master SCF network element and the standby SCF network element. The target perception task is sent to the second perception RAN and the third perception RAN instead of the master SCF network element, so that the second perception RAN and the third perception RAN execute the target perception task and feed back the perception data to the standby SCF network element. In the process of sending the target perception task, the standby SCF network element can also receive a third perception task sent by a demand network element and send the third perception task to the second perception RAN and the third perception RAN.

[0111] Optionally, in some embodiments, when the running state of the master SCF network element is in the normal state, an optional implementation of the perception task processing method is that the master SCF network element receives a fourth perception task sent by a demand network element. According to a target perception area in the fourth perception task, a target perception RAN is determined. If the target perception RAN contains a certain perception RAN in the second perception RAN, the fourth perception task is sent to the backup SCF network element, and the backup SCF network element sends the fourth perception task to the target perception RAN. If the target perception RAN also includes a certain perception RAN in the third perception RAN, the fourth perception task is directly sent to the target perception RAN in the third perception RAN by the master SCF network element.

[0112] Optionally, before obtaining the running state of the master SCF network element in the target perception network in the embodiment, an optional implementation of the perception task execution method is that a second perception capability registration request initiated by a second perception RAN based on a single registration strategy is received. The single registration strategy is a strategy in which the second perception RAN initiates a perception capability registration only to the backup SCF network element. The second perception capability registration request further includes at least one of a supported perception capability set, a perception area, a perception type, and a refresh rate. Based on the perception capability registration request, a perception capability registration operation is performed on the second perception RAN. When the perception capability registration operation indicates that the registration is successful, a registration success response message is sent to the second perception RAN.

[0113] Optionally, before sending the target perception task to the third perception RAN instead of the master SCF network element in the embodiment, an optional implementation of the perception task execution method is that a third perception capability registration request initiated by a third perception RAN is received. The third perception capability registration request is sent by the third perception RAN to the backup SCF network element when it is determined that the running state of the master SCF network element is in the fault state. Based on the third perception capability registration request, a perception capability registration operation is performed on the third perception RAN. When the perception capability registration operation indicates that the registration is successful, a registration success response message is sent to the third perception RAN. That is, under the single registration strategy, when the third perception RAN determines that the running state of the master SCF network element is in the fault state, in order to guarantee the continuity of the perception task, the third perception task needs to initiate a third perception capability registration request to the backup SCF network element to complete the registration in the backup perception SCF network element. Optionally, the third perception RAN can obtain the running state of the master SCF network element by sending a heartbeat packet to the master SCF network element.

[0114] On the basis of the above-mentioned embodiments, in the case where the third perception RAN detects that the operation state of the master SCF network element returns to the normal state, an optional implementation of a perception task execution method is that a perception capability deregistration request initiated by the third perception RAN is received; wherein the perception capability deregistration request is sent by the third perception RAN to the backup SCF network element in the case where the operation state of the master SCF network element returns to the normal state. A deregistration response message is sent to the third perception RAN, so that the third perception RAN sends a fourth perception capability registration request to the master SCF network element in the case where the deregistration response message indicates that the deregistration is successful, so as to complete the perception capability registration of the master SCF network element. That is to say, when the third perception RAN detects that the operation state of the master SCF network element returns to the normal state, a perception capability deregistration request is initiated to the backup SCF network element to complete the deregistration of the backup SCF network element, and a registration needs to be initiated to the master SCF network element again, and the perception task is allocated by the master SCF network element to the third perception RAN subsequently.

[0115] S602, receiving the perception data sent by the second perception RAN and the third perception RAN, and feeding back the perception data to the demand network element.

[0116] In the embodiment, in the case where the registration strategy executed by the first perception RAN in the target perception network is the single registration strategy, when the third perception RAN detects that the operation state of the master SCF network element is the fault state, a third perception capability registration request is sent to the backup SCF network element to complete the perception capability registration of the backup SCF network element. The backup SCF network element sends target perception tasks to the second perception RAN and the third perception RAN instead of the master SCF network element according to the perception task information in the perception task association information synchronized between the master SCF network element and the backup SCF network element, so that the second perception RAN and the third perception RAN execute the target perception tasks, which not only increases the flexibility of the perception task execution, but also guarantees the stability and continuity of the perception service.

[0117] In one of the embodiments, in the case where the registration strategy of the first perception RAN in the target perception network is the double registration strategy, as shown in FIG. 8, an optional implementation of a perception task execution method includes the following steps: Figure 7

[0118] The first perception RAN sends a first perception capability registration request to the master SCF network element and the backup SCF network element respectively. Wherein, the first perception RAN is an effective perception RAN in the target perception network.

[0119] The master SCF network element and the backup SCF network element perform a perception capability registration operation on the first perception RAN based on the first perception capability registration request.

[0120] ​The main SCF network element and the backup SCF network element send a registration success response message to the first sensing RAN in the case that the sensing capability registration operation is successfully registered.

[0121] The backup SCF network element periodically sends a heartbeat packet to the main SCF network element, so that the main SCF network element feeds back a response packet based on the heartbeat packet.

[0122] According to the response packet fed back by the main SCF network element, the running state of the main SCF network element in the target sensing network is obtained.

[0123] In the case that the running state is a fault state, the target sensing task is sent to the first sensing RAN by the main SCF network element and the backup SCF network element according to the sensing task information in the synchronized sensing task association information and / or the received sensing task sent by the demand network element.

[0124] The first sensing RAN executes the target sensing task and feeds back sensing data to the backup SCF network element.

[0125] The sensing data fed back by the first sensing RAN is received and the sensing data is fed back to the demand network element.

[0126] In the embodiment, the identity change process of the SCF network element is also included, and specifically as follows:

[0127] In the case that the running state is a fault state, the backup SCF network element is taken as a new main SCF network element.

[0128] In the case that the running state is restored to a normal state, the main SCF network element is taken as a new backup SCF network element.

[0129] In one of the embodiments, in the case that the registration strategy of the first sensing RAN in the target sensing network is a single registration strategy, as shown in FIG. 1, an optional implementation of a sensing task execution method includes: Figure 8

[0130] The second sensing RAN sends a second sensing capability registration request to the backup SCF network element. The second sensing RAN is the SCF network element in the target sensing network.

[0131] The backup SCF network element performs a sensing capability registration operation on the second sensing RAN based on the second sensing capability registration request.

[0132] The backup SCF network element sends a registration success response message to the second sensing RAN in the case that the sensing capability registration operation is successfully registered.

[0133] ​The third awareness RAN sends a fifth awareness capability registration request to the primary SCF network element. The third awareness RAN is the SCF network element in the target awareness network and the SCF network element in the primary SCF network element. The first awareness RAN includes the second awareness RAN and the third awareness RAN.

[0134] The primary SCF network element performs an awareness capability registration operation on the third awareness RAN based on the fifth awareness capability registration request.

[0135] The primary SCF network element sends a registration success response message to the third awareness RAN in a case where the awareness capability registration operation indicates that the registration is successful.

[0136] The third awareness RAN sends a third awareness capability registration request to the backup SCF network element in a case where the operation state of the primary SCF network element is determined to be a failure state.

[0137] The backup SCF network element receives the third awareness capability registration request initiated by the third awareness RAN. The third awareness capability registration request is sent by the third awareness RAN to the backup SCF network element in a case where the operation state of the primary SCF network element is determined to be a failure state.

[0138] The backup SCF network element performs an awareness capability registration operation on the third awareness RAN based on the third awareness capability registration request.

[0139] The backup SCF network element sends a registration success response message to the third awareness RAN in a case where the awareness capability registration operation indicates that the registration is successful.

[0140] The backup SCF network element sends target awareness tasks to the second awareness RAN and the third awareness RAN in place of the primary SCF network element in a case where the operation state of the primary SCF network element is determined to be a failure state, according to the awareness task information in the synchronized awareness task association information between the primary SCF network element and the backup SCF network element and / or the awareness tasks sent by the demand network element, so that the second awareness RAN and the third awareness RAN perform the target awareness tasks and feed back awareness data to the backup SCF network element.

[0141] The backup SCF network element receives the awareness data sent by the second awareness RAN and the third awareness RAN and feeds back the awareness data to the demand network element.

[0142] The third awareness RAN also includes an execution flow for detecting that the operation state of the primary SCF network element is restored to a normal state in the embodiment, and the execution flow is specifically as follows:

[0143] The third awareness RAN sends an awareness capability deregistration request to the backup SCF network element in a case where the operation state of the primary SCF network element is detected to be restored to a normal state.

[0144] The standby SCF network element receives the sensing capability deregistration request and performs deregistration on the third sensing RAN, and sends a deregistration response message to the third sensing RAN after the deregistration.

[0145] The third sensing RAN sends a fourth sensing capability registration request to the master SCF network element to complete the sensing capability registration at the master SCF network element in the case that the deregistration response message indicates that the deregistration is successful.

[0146] The sensing task execution method of the embodiment acquires the running state of the master SCF network element in the target sensing network. In the case that the running state is a fault state, the sensing task is executed by replacing the master SCF network element according to the synchronized sensing task association information between the master SCF network element and the standby SCF network element. In the application, the structure design of the master SCF network element and the standby SCF network element in the target sensing network enables the processing of the sensing task to support disaster recovery backup, ensuring the continuity and stability of the processing of the sensing task, providing technical support for the application of the sensing task in various scenarios, and improving user satisfaction.
