Description

TECHNICAL FIELD

[0002] With the development of communication technology, a new network system combining the characteristics of 5G high-speed transmission and sensing technology, i.e. a 5G sensing network system, has appeared. The system can include a sensing control plane function SCF and a sensing data processing function SPF. The sensing control plane function SCF is responsible for managing the registration of the sensing RAN capability and the task issuing, while the sensing data processing function SPF is mainly used for receiving sensing measurement data.

[0003] In the traditional technology, the fault handling scheme for the sensing network system is usually implemented by using the master-backup SCF data synchronization mechanism. The real-time synchronization of task data, RAN state and other information is used to realize the fault switching. However, the above processing method depends on the data synchronization function. The data synchronization needs to occupy the network bandwidth, increases the transmission cost, and the synchronization delay can easily cause the inconsistency of the master-backup data, causing the task execution abnormality. Moreover, the synchronization link itself has the risk of failure, which reduces the system reliability. Therefore, in the existing fault handling method for the sensing network system, the fault handling efficiency is poor, and the continuity of the 5G sensing service is poor. SUMMARY

[0051] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

[0052] It should be noted that the terms "first", "second", and the like used in the present application can be used to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish the first element from the second element. The terms "include" and "have" and any variations thereof used in the present application are intended to cover non-exclusive inclusion. The term "a plurality of" used in the present application refers to two or more. The term "and / or" used in the present application refers to one of the options or any combination of multiple options.

[0053] The perception task processing method provided by the embodiments of the present application can be applied to, for example, Figure 1The application environment shown. Among them, the perception RAN pre-registered in the main SCF awareness capability is communicated with the main SCF and the standby SCF through the communication link, the main SCF and the standby SCF are communicated with the perception task issuing module through the communication link, and there is no data synchronization channel between the main SCF and the standby SCF. Specifically, the perception task issuing module can issue the perception task associated with the perception RAN to the main SCF and the standby SCF, and the main SCF can send a corresponding task request to the perception RAN after receiving the perception task to respond to the perception task. Then if the perception RAN detects that the main SCF fails, it can send a perception capability registration request to the standby SCF to register the perception capability in the standby SCF. After the standby SCF completes the perception capability registration of the perception RAN, it can generate a first perception task request based on the received perception task associated with the perception RAN and send it to the perception RAN, and the perception RAN can respond to the first perception task request and return the first perception data to the standby SCF to respond to the perception task, so as to realize that even if there is no data synchronization channel between the main SCF and the standby SCF, the standby SCF can be switched to continue the execution of the perception task when the main SCF fails.

[0054] In one embodiment, as shown in Figure 2 , a perception task processing method is provided, and the method is applied to the perception RAN pre-registered in the main SCF in Figure 1 for example, including the following steps:

[0055] Step S201, in the case of detecting that the main SCF fails, a perception capability registration request is sent to the standby SCF corresponding to the main SCF to register the perception capability in the standby SCF; there is no data synchronization channel between the main SCF and the standby SCF.

[0056] Among them, the perception RAN can refer to a perception wireless access network device, which can pre-register the perception capability in the main SCF, and the main SCF refers to the main perception control plane function. The perception task processing communication system in the embodiment can include a main standby SCF module, which can be composed of two SCFs, namely the main SCF and the standby SCF corresponding to the main SCF. The standby SCF mainly substitutes the main SCF to execute the perception task processing and the registration of the perception capability when the main SCF fails, and in the embodiment, there is no data synchronization channel between the main SCF and the standby SCF.

[0057] Specifically, when performing the perception task request issued by the primary SCF, the perception RAN can detect the communication state with the primary SCF in real time, and if it is detected that the primary SCF fails, the perception RAN can send a perception capability registration request to the backup SCF corresponding to the primary SCF, so as to register the perception capability in the backup SCF, and complete the perception task through the backup SCF.

[0058] In step S202, a first perception task request returned by the backup SCF is received; the first perception task request is generated by the backup SCF according to the perception task associated with the perception RAN after the perception RAN registers the perception capability; the perception task associated with the perception RAN is sent to the primary SCF and the backup SCF by the perception task issuing module.

[0059] The first perception task request is sent by the backup SCF, and is used to instruct the perception RAN to perform the task request of the perception task, which is generated by the backup SCF based on the perception task associated with the perception RAN, and the perception task can be sent to the primary SCF and the backup SCF by the perception task issuing module. The perception task issuing module can be an application function module AF or a network exposure function module NEF. The above perception task issuing module can generate the perception task and issue the perception task to the primary SCF and the backup SCF at the same time, and then the primary SCF and the backup SCF filter out the perception RAN used to perform the perception task to initiate the perception task request to the above perception RAN, and the perception task associated with the perception RAN is the perception task that needs to be performed by the perception RAN.

[0060] Specifically, after the perception task issuing module generates the perception task, the perception task can be issued to the primary SCF and the backup SCF at the same time, so that the backup SCF can also obtain the perception task issued by the perception task issuing module as the primary SCF. After the perception RAN detects that the primary SCF fails and registers the perception capability with the backup SCF, the backup SCF can determine whether it is the perception task that needs to be performed by the perception RAN based on the received perception task, that is, whether it is the perception task associated with the perception RAN, and if so, the first perception task request can be generated according to the perception task associated with the perception RAN and sent to the perception RAN to request the perception RAN to perform the above perception task.

[0061] In step S203, in response to the first perception task request, the first perception data is returned to the backup SCF, so that the backup SCF reports the first perception data to the perception task issuing module.

[0062] The first perception data refers to the perception data reported by the perception RAN in response to the first perception task request. After the perception RAN receives the first perception task request returned by the backup SCF, the perception RAN can generate a task response to the task request, so as to return the corresponding first perception data to the backup SCF. The backup SCF can report the first perception data to the perception task issuing module, so as to complete the perception task.

[0063] In the above perception task processing method, the perception RAN that registers the perception capability in the master SCF in advance sends a perception capability registration request to the backup SCF corresponding to the master SCF in the case where it is detected that the master SCF fails, so as to register the perception capability in the backup SCF. There is no data synchronization channel between the master SCF and the backup SCF. The first perception task request returned by the backup SCF is received. The first perception task request is generated by the backup SCF according to the perception task associated with the perception RAN after the perception RAN registers the perception capability. The perception task associated with the perception RAN is sent to the master SCF and the backup SCF by the perception task issuing module. In response to the first perception task request, the first perception data is returned to the backup SCF, so that the backup SCF reports the first perception data to the perception task issuing module. In this application, when the perception RAN that registers the perception capability in the master SCF in advance detects that the master SCF fails, the perception capability registration request is actively sent to the backup SCF. After the backup SCF registers the perception capability of the perception RAN, it can also determine whether there is a perception task associated with the perception RAN sent by the perception task issuing module. If there is, a first perception task request is generated and sent to the perception RAN, so that the perception RAN can continue to execute the perception task issued by the perception task issuing module. In this way, even if there is no data synchronization channel between the master SCF and the backup SCF, the backup SCF can be actively switched to continue to execute the perception task, so that the fault processing efficiency can be improved, and the continuity of the 5G perception service can be ensured.

[0064] In one embodiment, before step S201, the method can further include: in response to the second perception task request sent by the master SCF, returning second perception data to the master SCF, so that the master SCF reports the second perception data to the perception task issuing module; and the second perception task request is generated by the master SCF according to the perception task associated with the perception RAN.

[0065] The second perception task request refers to the task request sent by the master SCF, which is used to instruct the perception RAN to execute the perception task. Before the master SCF fails, since the perception RAN registers the perception capability in the master SCF, the master SCF usually issues the perception task request to the perception RAN. The second perception data is the perception data reported by the perception RAN in response to the second perception task request.

[0066] Specifically, after the perception RAN receives the second perception task request returned by the master SCF, the perception RAN can perform a task response to the task request, so as to return the corresponding second perception data to the master SCF, and the master SCF can report the second perception data to the perception task issuing module, thereby completing the perception task.

[0067] For example, the specific execution process of the perception task can be as follows. A certain perception RAN can pre-register the perception capability in the master SCF. When the perception task issuing module generates a perception task, the perception task can be sent to the master SCF and the backup SCF. If the perception task needs to be executed by the perception RAN, the master SCF can generate a second perception task request and send it to the perception RAN, and the perception RAN can return second perception data, so that the master SCF reports the second perception data to the perception task issuing module. After that, if the perception RAN detects that the master SCF has failed, the perception RAN can send a perception capability registration request to the backup SCF to register the perception capability in the backup SCF. After the registration is completed, since the backup SCF also receives the perception task, the backup SCF can restart the perception task, that is, generate a first perception task request and return it to the perception RAN, and the perception RAN returns first perception data, so that the backup SCF reports the first perception data to the perception task issuing module to continue to complete the perception task.

[0068] In this embodiment, before the master SCF fails, the perception task response can be completed by the second perception task request sent by the master SCF. In this way, the stability and continuity of the perception task processing can be ensured.

[0069] In addition, before responding to the second perception task request sent by the master SCF, the method can further include: sending a communication link construction request to the master SCF and the backup SCF; the communication link construction request is used to construct a communication link between the perception RAN and the master SCF, and construct a communication link between the perception RAN and the backup SCF; after the communication link between the perception RAN and the master SCF is established, sending a perception capability registration request to the master SCF to register the perception capability in the master SCF.

[0070] In this embodiment, before the perception RAN executes the perception task, the perception capability registration in the master SCF needs to be completed in advance, and the perception capability registration depends on the communication between the perception RAN and the master SCF, so the communication link between the perception RAN and the master SCF needs to be constructed first. In order to ensure that when the master SCF fails, the perception RAN can register the perception capability in the backup SCF to continue to complete the perception task, the communication link between the perception RAN and the backup SCF also needs to be constructed.

[0071] Specifically, the perception RAN can send a communication link construction request to the primary SCF and the backup SCF respectively, and the primary SCF and the backup SCF can respectively reply to the perception RAN with a link construction response message, so as to complete the construction of the communication link between the perception RAN and the primary SCF, and the communication link between the perception RAN and the backup SCF. After the construction of the communication link between the perception RAN and the primary SCF is completed, the perception RAN can further send a perception capability registration request to the primary SCF through the communication link, and the primary SCF can return a perception capability registration response to the perception RAN, so as to complete the registration of the perception capability of the perception RAN in the primary SCF.

[0072] In the embodiment, the perception RAN can also send a communication link construction request to the primary SCF and the backup SCF respectively, so as to construct the communication link between the perception RAN and the primary SCF, and the communication link between the perception RAN and the backup SCF. Then, the perception capability of the perception RAN can be registered in the primary SCF through the communication link, and the communication link between the perception RAN and the backup SCF can be used to register the perception capability of the perception RAN in the backup SCF after the primary SCF fails. In this way, the perception RAN can pre-register the perception capability in the primary SCF, and the possibility of continuing to perform the perception task after the primary SCF fails is provided, so as to further improve the efficiency and stability of the perception task processing.

[0073] In one embodiment, after step S203, the method can further include: in the case that an operation and maintenance instruction is received, re-sending a perception capability registration request to the primary SCF, so as to re-register the perception capability in the primary SCF; the operation and maintenance instruction is sent by the primary SCF after the primary SCF fails and recovers, and is sent to the perception RAN through an operation and maintenance system, so as to instruct the perception RAN to re-register the perception capability in the primary SCF.

[0074] The operation and maintenance instruction refers to an instruction sent by the primary SCF, which is used to instruct the perception RAN to re-register the perception capability in the primary SCF. The operation and maintenance instruction can be sent by the primary SCF to the perception RAN through an operation and maintenance system. Specifically, after the primary SCF fails and recovers, the operation and maintenance instruction for re-adjusting the registration can be issued to the perception RAN through the operation and maintenance system, so as to require the perception RAN to re-register the perception capability in the recovered primary SCF. After the perception RAN receives the operation and maintenance instruction, the perception RAN can send a perception capability registration request to the primary SCF, so as to re-register the perception capability in the primary SCF.

[0075] In this embodiment, after the main SCF recovers from the failure, the operation and maintenance system can also send an operation and maintenance instruction to the sensing RAN to instruct the sensing RAN to re-register the sensing capability with the main SCF. After the sensing RAN receives the operation and maintenance instruction, the sensing RAN can re-send a sensing capability registration request to the main SCF to re-register the sensing capability with the main SCF. In this way, the sensing RAN can be brought back into the management range of the main SCF after the main SCF recovers from the failure, the management of the sensing task is restored, and the stable operation of the sensing task after the failure is repaired can be ensured.

[0076] In one embodiment, before step S101, the method can further include: in a case where it is detected that the communication with the main SCF is interrupted, acquiring a communication interruption duration; and in a case where the communication interruption duration is greater than a preset interruption duration threshold, determining that the main SCF has failed.

[0077] The communication interruption duration refers to the duration of the interruption state of the communication with the main SCF, and the preset interruption duration threshold refers to a preset interruption duration threshold for determining whether the main SCF has failed. Specifically, the sensing RAN can monitor the communication state with the main SCF in real time. If the sensing RAN detects that the communication with the main SCF is interrupted, the interruption duration of the communication interruption can be acquired. Then, it can be determined whether the communication interruption duration is greater than the preset interruption duration threshold. The duration threshold can be 30 s. At this time, it can be determined that the current main SCF has failed.

[0078] In this embodiment, when the sensing RAN detects that the communication with the main SCF is interrupted, the communication interruption duration can also be acquired. If the communication interruption duration is greater than the preset interruption duration threshold, it is determined that the main SCF has failed. In this way, the accuracy of the main SCF failure detection can be improved.

[0079] In one embodiment, as shown in Figure 3 , a sensing task processing method is also provided. The method is applied to the backup SCF in Figure 1 for example, and includes the following steps:

[0080] Step S301: receiving and saving a sensing task. The sensing task is sent to the main SCF and the backup SCF by a sensing task issuing module.

[0081] Specifically, after generating the sensing task, the sensing task issuing module can simultaneously issue the sensing task to the main SCF and the backup SCF. After the backup SCF receives the sensing task, the task information of the sensing task can be saved to the local storage for possible subsequent calling.

[0082] Step S302, in response to the sensing capability registration request initiated by the sensing RAN which registers the sensing capability in the master SCF in advance, the sensing capability of the sensing RAN is registered; the sensing capability registration request is sent by the sensing RAN in the case of detecting that the master SCF fails.

[0083] After that, if the sensing RAN which registers the sensing capability in the master SCF in advance detects that the master SCF fails, the sensing RAN can send a sensing capability registration request for registering the sensing capability in the backup SCF to the backup SCF, and the backup SCF can respond to the sensing capability registration request sent by the sensing RAN, thereby registering the sensing capability of the sensing RAN and adding it to the local management list.

[0084] Step S303, in the case that there is a sensing task associated with the sensing RAN in the saved sensing task, a first sensing task request is generated according to the sensing task associated with the sensing RAN, and the first sensing task request is sent to the sensing RAN to receive the first sensing data returned by the sensing RAN according to the first sensing task request;

[0085] Step S304, the first sensing data is sent to the sensing task issuing module.

[0086] The sensing task associated with the sensing RAN refers to the sensing task that needs to be executed by the sensing RAN. Since the task information of each sensing task sent by the sensing task issuing module is also saved in the backup SCF, after the sensing RAN completes the registration of the sensing capability, the retrieval of the task information of the locally saved sensing task can be started to confirm whether there is a sensing task that needs to be executed by the sensing RAN after the registration is completed, that is, whether there is a sensing task associated with the sensing RAN in the saved sensing task. If there is, a corresponding task request can be generated according to the sensing task associated with the sensing RAN, that is, a first sensing task request is generated, and the first sensing task request is sent to the sensing RAN.

[0087] After the sensing RAN receives the first sensing task request, the sensing RAN can respond to the first sensing task request, thereby returning the sensing data corresponding to the first sensing task request to the backup SCF, that is, returning the first sensing data, and the backup SCF can send the first sensing data to the sensing task issuing module after receiving the first sensing data, thereby completing the sensing task.

[0088] In the above perception task processing method, the perception task is received and saved by the backup SCF without a data synchronization channel with the main SCF; the perception task is sent to the main SCF and the backup SCF by a perception task issuing module; in response to a perception capability registration request initiated by the perception RAN that has registered the perception capability in the main SCF in advance, the perception capability of the perception RAN is registered; the perception capability registration request is sent by the perception RAN in the case where the main SCF is detected to have failed; in the case where there is a perception task associated with the perception RAN in the saved perception task, a first perception task request is generated according to the perception task associated with the perception RAN, and the first perception task request is sent to the perception RAN to receive first perception data returned by the perception RAN according to the first perception task request; and the first perception data is sent to the perception task issuing module. When the perception RAN that has registered the perception capability in the main SCF in advance detects that the main SCF has failed, the perception capability registration request can be actively sent to the backup SCF, the perception capability of the perception RAN is registered by the backup SCF, and then it can be judged whether there is a perception task associated with the perception RAN sent by the perception task issuing module. If there is, a first perception task request is generated and sent to the perception RAN, so that the perception RAN can continue to execute the perception task issued by the perception task issuing module. In this way, even if there is no data synchronization channel between the main SCF and the backup SCF, the backup SCF can be actively switched to continue the execution of the perception task, so that the fault handling efficiency can be improved, and the continuity of the 5G perception service can be ensured.

[0089] Further, the perception task stores task area information; after step S302, the method can further include: obtaining the perception area information of the perception RAN from the perception capability registration request; and if the task area information of any saved perception task overlaps with the perception area information, determining that the perception task is a perception task associated with the perception RAN.

[0090] The task area information refers to the area information that needs to be perceived by the perception task. The area information can be part of the task information of the perception task, for example, the task information of the perception task records the task area coordinates as area A, and the perception task needs to perceive area A. The perception area information refers to the perception area range of the perception RAN, which can be carried in the perception capability registration request initiated by the perception RAN.

[0091] Specifically, after the registration of the perception RAN is completed, the backup SCF can also search the task information saved locally based on the perception area. If the task area information of a certain perception task saved by the backup SCF overlaps with the perception area information, that is, the task area of a certain perception task contains the perception area range of the perception RAN, the perception task can be regarded as a perception task associated with the perception RAN, so as to reactivate the perception task.

[0092] In the embodiment, the perception task can be retrieved according to the perception area information of the RAN, so as to filter out the perception task associated with the RAN. In this way, the perception task can be reactivated by retrieving the matching relationship between the task area and the newly registered RAN, so as to ensure the stable operation of the perception task.

[0093] In one embodiment, as shown in FIG. 4, a perception task processing system is also provided, which can include a perception task issuing module 401, a master SCF 402, a backup SCF 403 corresponding to the master SCF 402, and a perception RAN 404 that has registered perception capability with the master SCF 402 in advance, and there is no data synchronization channel between the master SCF 402 and the backup SCF 403. Figure 4

[0094] The perception task issuing module 401 is configured to issue the perception task to the master SCF 402 and the backup SCF 403.

[0095] The backup SCF 403 is configured to receive and save the perception task.

[0096] The perception RAN 404 is configured to send a perception capability registration request to the backup SCF 403 when detecting that the master SCF 402 has failed.

[0097] The backup SCF 403 is further configured to respond to the perception capability registration request, register the perception capability of the perception RAN 404, and when there is a perception task associated with the perception RAN 404 in the saved perception task, generate a first perception task request according to the perception task associated with the perception RAN 404, and send the first perception task request to the perception RAN 404.

[0098] The perception RAN 404 is further configured to respond to the first perception task request, and return first perception data to the backup SCF 403.

[0099] The backup SCF 403 is further configured to report the first perception data to the perception task issuing module 401.

[0100] In the embodiment, the perception task processing system can include the following modules: a perception task issuing module 401, a master-backup SCF module, and a perception RAN module. The master-backup SCF module can include the master SCF 402 and the backup SCF 403, and there is no data synchronization link between the master SCF 402 and the backup SCF 403. The perception RAN module can be composed of multiple perception RANs, including the perception RAN 404 that has registered perception capability with the master SCF 402 in advance.

[0101] ​Specifically, the perception task issuing module 401 can generate a perception task and issue the perception task to the primary SCF 402 and the backup SCF 403 respectively. After receiving the perception task, the backup SCF 403 can save the perception task.

[0102] Afterwards, if the perception RAN 404 detects that the primary SCF 402 fails, the perception capability registration request can be sent to the backup SCF 403. The backup SCF 403 can respond to the perception capability registration request, register the perception capability of the perception RAN 404, and query the perception task associated with the perception RAN 404 from the saved perception task, thereby generating a first perception task request and sending it to the perception RAN 404.

[0103] After receiving the first perception task request, the perception RAN 404 can respond to the request, thereby obtaining the first perception data corresponding to the first perception task request, and return to the backup SCF 403. The backup SCF 403 reports the first perception data to the perception task issuing module 401 to complete the perception task.

[0104] In the above perception task processing system, when the perception RAN 404 that has registered the perception capability with the primary SCF 402 detects that the primary SCF 402 fails, the perception capability registration request can be actively sent to the backup SCF 403. After the backup SCF 403 registers the perception capability of the perception RAN 404, it can further determine whether there is a perception task associated with the perception RAN 404 sent by the perception task issuing module 401. If there is, a first perception task request is generated and sent to the perception RAN 404, so that the perception RAN 404 can continue to execute the perception task issued by the perception task issuing module 404. Through this way, even if there is no data synchronization channel between the primary and backup SCFs, the backup SCF can be actively switched to continue the execution of the perception task, thereby improving the fault handling efficiency and ensuring the continuity of the 5G perception service.

[0105] In one embodiment, the primary SCF 402 is configured to receive a perception task, and in the case that the perception task is a perception task associated with the perception RAN 404, generate a second perception task request according to the perception task associated with the perception RAN. The perception RAN 404 is further configured to respond to the second perception task request and return second perception data to the primary SCF. The primary SCF 402 is further configured to report the second perception data to the perception task issuing module.

[0106] If the main SCF 402 does not fail, after the sensing task issuing module 401 issues the sensing task to the main SCF 402, the main SCF 402 can retrieve the sensing RAN that needs to execute the sensing task according to the issued sensing task. If the sensing task needs to be executed by the sensing RAN 404, the sensing task is the sensing task associated with the sensing RAN 404. At this time, the main SCF 402 can generate a second sensing task request according to the sensing task associated with the sensing RAN 404, and send it to the sensing RAN 404.

[0107] After the sensing RAN 404 receives the second sensing task request, it can respond to the request to obtain the second sensing data corresponding to the second sensing task request, and return to the main SCF 402. The main SCF 402 reports the second sensing data to the sensing task issuing module 401. In this way, when the main SCF 402 is normal, the main SCF 402 can complete the sensing task.

[0108] In the embodiment, before the main SCF 402 fails, the second sensing task request sent by the main SCF 402 can complete the sensing task response. In this way, the stability and continuity of the sensing task processing can be ensured.

[0109] In one embodiment, a no-data synchronization based main-backup SCF disaster recovery switching method and system are also provided, which can cancel the data synchronization link of the main-backup SCF, simplify the network architecture, improve the disaster recovery switching efficiency, and ensure the continuity of the 5G sensing service. The method can be applied to a 5GC sensing fusion architecture. The architecture introduces a sensing function, which is fused with the existing 5GC architecture, and reuses the existing 5GC functions, interfaces and protocols to realize end-to-end communication and the cooperation of sensing capabilities. Figure 5 As shown in the figure, the architecture adds a sensing control plane function (SCF) and a sensing data processing function (SPF). The SPF supports receiving sensing measurement data and can be centrally deployed or deployed at the edge. There are usually multiple SPFs, which usually implement disaster recovery processing in a load sharing manner. The SCF supports the transmission of control plane messages, including sensing capability management and sensing task management, and is usually centrally deployed. When the SCF fails, the sensing tasks that have been issued cannot be executed, and new tasks cannot be normally issued, which seriously affects the service continuity. Therefore, the embodiment is mainly used for solving the disaster recovery backup of the SCF.

[0110] As shown in the figure, the no-data synchronization based main-backup SCF disaster recovery communication system includes: Figure 6

[0111] ​1. Master and backup SCF modules: including SCF1 and SCF2, no data synchronization link between them; support receiving AF issued sensing tasks, only manage sensing RANs registered thereto and task activation; support activating tasks of the sensing RANs managed by each other based on the task area, and save the task information if the task area has no intersection with the managed area.

[0112] 2. Sensing RAN module: configured with the communication addresses of SCF1 and SCF2, and a bidirectional communication link is established with them; in the initial state, only register the sensing capability to SCF1; capable of detecting the failure of the master SCF1 and automatically switching to SCF2 to re-register the sensing capability.

[0113] 3. AF / NEF module: simultaneously issues the same sensing task to SCF1 and SCF2.

[0114] 4. Task management module: integrated in SCF1 and SCF2, used for storing sensing task information, listening to RAN registration messages, retrieving matching tasks according to the RAN registration area and triggering activation instructions.

[0115] Task storage unit: used for saving the sensing tasks issued by AF, including task ID, task area, execution period, data reporting frequency, and task priority;

[0116] Real-time monitoring unit: used for listening to the registration messages of RAN, and automatically triggering the task retrieval process when receiving the registration request;

[0117] Area matching unit: used for extracting the coverage area of the newly registered RAN, and performing intersection detection with the task area in the task storage unit;

[0118] Activation instruction unit: used for sending task reactivation instructions to the RANs with successful matching.

[0119] The specific implementation method can be as follows:

[0120] The system architecture includes SCF1 (master SCF), SCF2 (backup SCF), multiple sensing RANs (RAN1, RAN2, RAN3), and AF (application function). There is no data synchronization channel between SCF1 and SCF2, the sensing RANs are preconfigured with the IP addresses and communication ports of SCF1 and SCF2, and TCP links are established with them through the IP-RAN transmission network.

[0121] The business scenario assumes that sensing RAN1 and sensing RAN2 initially register sensing capability to SCF1, which is included in the management range of SCF1; sensing RAN3 initially registers sensing capability to SCF2 (a small number of RANs are managed by the default backup SCF as hot standby); the task area of the task issued by AF only includes the sensing areas of RAN1 and RAN2; the intermediate SCF1 fails and then recovers.

[0122] The whole service flow is as shown in the following figure, and specifically includes the following steps: Figure 7

[0123] 1a / 1b / 1c / 1d, RAN1~RAN3 send a link establishment request message to SCF1 and SCF2, carrying information such as PLMN and gNodeB ID.

[0124] 2a / 2b / 2c / 2d, SCF1 and SCF2 return a link establishment response message to RAN1~RAN3. The SCF receives the link establishment request message and returns a success response message; otherwise, a failure response message is returned, carrying a failure reason value.

[0125] 3a / 3b, RAN1 and RAN2 initiate an awareness capability registration request to SCF1, and RAN3 initiates an awareness capability registration request to SCF2, and the request message carries the awareness capability basic data of the RAN, including the awareness unit ID of the RAN, the supported awareness frequency band, the awareness accuracy, the awareness refresh rate, the awareness area, the awareness type (such as millimeter wave radar and camera), and other capability parameters.

[0126] 4a / 4b, SCF1 returns an awareness capability registration response to RAN1 and RAN2, and SCF2 returns an awareness capability registration response to RAN3.

[0127] 5a / 5b, the AF generates an awareness task and simultaneously issues a task request to SCF1 and SCF2, and the task information includes a task ID, a target area coordinate of the task (such as area A), an execution period, a data reporting frequency, a task priority, and the like.

[0128] 6a / 6b, SCF1 and SCF2 return an awareness task response to the AF. Meanwhile, based on the task area “area A”, it is checked whether the awareness RAN managed by itself has an intersection with the area, and the subsequent execution step is decided. After checking that the task area “area A” has an intersection with the awareness areas of RAN1 and RAN2 managed by itself, SCF1 immediately issues an awareness task request to the awareness RAN1 and RAN2, notifying the activation of the task; SCF2 checks that the task area “area A” has no intersection with the awareness area of the awareness RAN3 managed by itself, and then responds successfully and saves the task information to a local storage for possible subsequent calling.

[0129] 7, SCF1 issues an awareness task to RAN1 and RAN2.

[0130] 8, RAN1 and RAN2 execute the awareness task and report awareness data to SCF1.

[0131] 9, SCF1 reports the awareness data to the AF.

[0132] ​10. SCF1 fails.

[0133] 11. The sensing RAN1 and RAN2 monitor the communication state with SCF1 in real time, and when detecting that the communication with SCF1 is interrupted and the interruption state lasts for a preset determination duration, it is determined that SCF1 fails. The preset duration can be reasonably set according to the actual network situation to ensure the accuracy of the failure determination, such as not receiving the heartbeat response of SCF1 for 3 times (timeout time 30s).

[0134] 12. The RAN1 and RAN2 automatically enable the standby SCF address and send a sensing capability registration request to SCF2.

[0135] 13. SCF2 returns a sensing capability registration response and adds it to the local management list.

[0136] 14. After receiving the sensing capability registration of the sensing RAN1 and RAN2, SCF2 automatically starts to retrieve the locally saved task information. The retrieval is based on whether the task area contains the sensing area of the newly registered RAN1 and RAN2. The coverage area information of the sensing RAN1 and RAN2 is extracted from the registration request, which can be stored in the form of a latitude-longitude polygon coordinate string (such as "North Latitude A-East Longitude A, North Latitude B-East Longitude B..."), which is uniformly converted into WGS-84 coordinate system by a coordinate conversion module to eliminate the coordinate system differences of different base stations. Through the area matching algorithm, the "area A sensing task" that overlaps with the sensing area of RAN1 and RAN2 is found, and then SCF2 sends a sensing task request to the sensing RAN1 and RAN2 to notify the reactivation of the "area A sensing task".

[0137] 15. The RAN1 and RAN2 execute the sensing task and report the sensing data to SCF2.

[0138] 16. SCF2 reports the sensing data to AF.

[0139] 17. When SCF1 recovers normally, the operation and maintenance system can send an instruction to the sensing RAN1 and RAN2 to re-register and require the RAN to re-register with the recovered SCF1.

[0140] 18. After receiving the operation and maintenance instruction, the sensing RAN1 and RAN2 re-initiate the sensing capability registration request to SCF1.

[0141] 19. SCF1 returns a sensing capability registration response and re-includes the sensing RAN1 and RAN2 in the management range to recover the management of the sensing task thereof.

[0142] Through the embodiment, a disaster recovery mechanism is designed for service characteristics of the SCF, a 1+1 paired disaster recovery architecture is used to set up a primary SCF and a backup SCF, and there is no data synchronization channel between the primary SCF and the backup SCF; a communication link is established between a sensing RAN and the primary SCF and the backup SCF, and only the primary SCF registers sensing capability, and when the primary SCF fails, the backup SCF is automatically switched to re-register; the AF simultaneously issues a sensing task to the primary SCF and the backup SCF, the SCF activates the task based on a management area, and after the failure switching, the backup SCF reactivates the task by searching for a matching relationship between the task area and the newly registered RAN. Therefore, the path dependence on data synchronization is broken, the service continuity problem after SCF failure is solved without a synchronization link by reconstructing the service process (task issuance, registration triggering, and area searching), and the three technical means of "RAN double-link chain establishment and dynamic registration", "AF task double-issuance", and "SCF area task search activation" are organically combined to realize that task data is not lost, the original task is quickly activated, and the service interruption time is shortened.
