[0002] In an integrated sensing and communication network, both communication and sensing services are achieved through a single set of equipment and a single network. Furthermore, with continuous technological advancements, to reduce equipment construction costs, a shared access network is used to jointly build and share a single network.

[0003] Currently, there are no unified standards for sensing technology both domestically and internationally. The current integrated sensing technology is still in the single-operator technical verification stage, and there has been no discussion on the implementation of sensing services under a shared network of multiple operators. Summary of the Invention

[0004] This application provides a shared network sensing method, apparatus, electronic device, and storage medium, which can realize sensing services under a shared network of multiple operators.

[0005] To achieve the above objectives, this application adopts the following technical solution: Firstly, this application provides a shared network sensing method, applied to a sensing function network element in the core network of a first operator in a shared network, wherein the core networks of multiple operators in the shared network are jointly connected to an access network.

[0046] In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0047] The following explanations of the terms used in the embodiments of this application are provided to facilitate the reader's understanding.

[0048] 1. Wireless Sensing: The technical principles of wireless sensing differ somewhat from those of wireless communication. For example, in wireless communication, the transmitting end modulates information onto radio waves and sends it to the receiving end, which then demodulates the signal carried on the radio waves to obtain the information. In a sensing scenario, the transmitting device radiates electromagnetic waves into the surrounding environment to send sensing signals. The receiving device receives the sensing signals reflected from the surrounding environment and analyzes and compares them with the transmitted sensing signals to perceive relevant information about the surrounding environment, such as the presence of the target, the number of targets, and the location of each target.

[0049] 2. Integrated communication and sensing: In the evolution from fifth-generation (5G) wireless communication technology to 5G-Advanced (5G-A) and future communication technologies, integrated communication and sensing technology is considered one of the key technologies for expanding the service capabilities of mobile communication networks. The core idea of ​​this technology is to add sensing capabilities to the mobile communication network, building capabilities for target localization, detection, imaging, and identification, thereby integrating communication and sensing capabilities into a single network, achieving harmonious coexistence, and enhancing user experience.

[0050] In integrated communication sensing, from the perspective of sensing modes, it can include single-site sensing mode and dual-site sensing mode. Single-site sensing mode includes base station self-transmission and self-reception mode and terminal self-transmission and self-reception mode. Dual-site sensing mode includes base station A transmitting and base station B receiving mode, base station transmitting and terminal receiving mode, terminal transmitting and base station receiving mode, and terminal A transmitting and terminal B receiving mode.

[0051] The basic principle of integrated communication and sensing is to use the same set of equipment and network to implement both communication and sensing services, thereby extending the tasks of the communication network and universalizing sensing services. Generally, communication networks have a wider deployment range, and sensing services are easier to deploy on communication networks, providing broader sensing coverage. Therefore, research on communication-based integrated communication and sensing networks and related fields is currently a mainstream research direction. After integration, on the one hand, the communication network can carry sensing services, thus replacing the resource waste caused by the simultaneous existence of two sets of equipment (communication and sensing networks). On the other hand, the high degree of integration between sensing and communication can break down the current barriers to information exchange between them, allowing communication to enhance its capabilities based on sensing needs. Currently, research on integrated communication and sensing technology is still in its early stages, and there are no unified standards or specifications yet.

[0052] Figure 1 This is a perception flowchart provided for an embodiment of this application. Figure 1 As shown, the perception service typically includes three processes: perception capability reporting, perception measurement configuration, and perception result reporting.

[0053] I. Reporting of Perception Ability The purpose of reporting sensing capabilities is primarily to enable sensing function (SF) network elements to obtain the sensing capabilities of the gNB and user equipment (UE), and to select the sensing mode and appropriate gNB based on the service requirements of application function (AF) network elements. The base station needs to report sensing capabilities in all modes: base station self-transmitting and self-receiving mode, base station A transmitting and base station B receiving mode, base station transmitting and terminal receiving mode, and terminal transmitting and base station receiving mode.

[0054] For example, the AF network element can serve as a sensing application platform, primarily responsible for connecting with external data application providers (such as air traffic control departments / UAV platforms), providing sensing data information services, and supporting applications in different industries. The SF network element is mainly responsible for sensing service control and data aggregation and forwarding.

[0055] II. Sensing Measurement Configuration Sensing measurement configuration includes both air interface resource-related configurations and non-resource-related configurations. Air interface resource-related configurations include the configuration of measurement signals, i.e., the time-frequency resource configuration information of the signals. Since the base station is responsible for air interface resource scheduling, the UE's air interface resource-related configurations are handled by the base station. Non-resource-related configurations mainly involve sensing process-related configurations, including sensing mode selection, transceiver role determination, and reporting mode configuration information, which can be determined by the SF network element based on sensing service requirements and sent to the base station or terminal.

[0056] Among them, the sensing modes include base station self-transmission and self-reception mode, terminal self-transmission and self-reception mode, base station A transmission and base station B reception mode, base station transmission and terminal reception mode, terminal transmission and base station reception mode, and terminal A transmission and terminal B reception mode.

[0057] Roles in different perception modes include: receiver, sender, and receiver & sender.

[0058] The perceived quality of service (QoS) requirements include requirements for perception accuracy, latency, etc.

[0059] Reporting modes include periodic reporting, event reporting, and event-triggered periodic reporting.

[0060] The configuration of base station measurement signals includes determining the configuration of the base station measurement signals based on the sensing mode. For example, the sensing mode may be a base station self-transmitting and self-receiving mode, a base station A transmitting and base station B receiving mode, or a base station transmitting and terminal receiving mode.

[0061] In the configuration of base station receiving echo signals, for the mode of base station A transmitting and base station B receiving, it is necessary to indicate the measurement configuration when base station B plays the role of "receiving".

[0062] The auxiliary information for sensing includes information that assists in transmitting and receiving sensing signals. For example, the information for transmitting auxiliary sensing signals includes direction information, which facilitates the determination of the transmission beam of the sensing signal. The information for receiving auxiliary sensing signals includes the time domain, frequency domain, code domain, and spatial domain configuration of the sensing signal to be received.

[0063] III. Reporting of Perception Results Sensing result reporting refers to the base station reporting the obtained sensing measurement data to the SF network element. For the three modes—base station self-transmission and self-reception, base station A-transmission and B-reception, and terminal-transmission and base station-reception—the base station processes the echo signal to obtain sensing measurement data and reports it to the SF network element. However, for scenarios involving terminal self-transmission and self-reception, terminal A-transmission and B-reception, and base station-transmission and terminal-reception, the base station is responsible for managing and allocating air interface resources and does not act as a sensing node to receive and aggregate related sensing signals. The transmission of sensing measurement data is transparent to the base station; that is, the sensing measurement data is obtained by the terminal processing the sensing signal, and the terminal sends the sensing measurement data to the SF network element through the base station. The base station does not parse the sensing measurement data; it only receives or sends the sensing measurement data.

[0064] Furthermore, from the perspective of network architecture, shared network architecture is also constantly evolving as technology continues to advance.

[0065] Specifically, the construction and operation costs of 5G networks are far higher than those of 4G. To reduce the number of network devices required and improve network efficiency and asset operation efficiency, China is currently adopting a "2+2" approach to mobile network co-construction and sharing. China Unicom and China Telecom officially began 5G network co-construction and sharing in September 2019, reaching an agreement to share a single 5G network throughout its entire lifecycle using access network sharing. The aim is to reduce the overall investment costs of network construction and operation for operators through 5G network co-construction and sharing, quickly achieve continuous wide-area 5G coverage, thereby improving the overall competitiveness of the industry and promoting high-quality development for enterprises. In May 2020, China's other two mobile communication operators, China Mobile and China Broadcasting Network, also began using access network sharing to build 5G networks, striving for mutually beneficial development. By early 2025, domestic operators had built millions of shared base stations using access network sharing, achieving coverage of all prefecture-level cities and county-level urban areas nationwide, and also covering most townships. Furthermore, as 6G communication networks develop towards a more three-dimensional and intelligent form, and everything transitions from interconnectedness to intelligent interconnection, the performance and scale of communication networks will inevitably continue to improve. Simultaneously, as communication gradually integrates deeply with computing, sensing, and intelligence capabilities, 6G co-construction and sharing will also be an important trend in 6G network development.

[0066] Access network sharing refers to a situation where shared operators only share wireless base station equipment and part of the transmission, but the core network is still built independently by each operator. Figure 2 This is a schematic diagram of a 5G access network sharing architecture provided in an embodiment of this application. Figure 2 As shown, the 5G shared base station provides services to users of both Operator A and Operator B. Simultaneously, the shared base station connects to both Operator A's and Operator B's bearer networks. Operator A's bearer network is connected to its core network, and Operator B's bearer network is connected to its core network. The shared base station can connect users to their home core network based on their network ID. In this access network sharing scenario, Operator A's and Operator B's core networks are independently constructed, thus giving them independent billing and user management rights, and enabling interoperability between the 5G shared network and their respective LTE networks.

[0067] Currently, there are no unified standards for sensing technology both domestically and internationally. The current integrated sensing technology is still in the single-operator technical verification stage, and there has been no discussion of sensing mode selection schemes for multi-operator shared networks. Although some manufacturers have proprietary implementation schemes for sensing mode selection in single-operator network construction scenarios, shared networks have some unique characteristics in terms of network architecture and service implementation processes. If the sensing mode selection scheme used in a single-operator non-shared network is applied to a multi-operator co-constructed shared network, the following problems will arise: First, in the current non-shared network architecture, even if multiple SF network elements exist in the network, each SF network element is responsible for its own area. In a co-constructed and shared network, especially in the access network sharing architecture commonly used by domestic operators, if the SF network elements between operators are not shared, the same shared base station will simultaneously connect to SF network elements from different operators, leading to overlapping areas covered by the SF network elements from different operators. In a shared network, SF network elements from different operators can all issue sensing tasks to the same shared base station, and since the SF network elements of different operators do not communicate with each other, sensing task conflicts may occur.

[0068] Secondly, reporting perception results may involve user privacy issues, especially when using perception modes involving UE participation. Obtaining user authorization is crucial, but user authorization is usually directed to their home operator. Therefore, when selecting UEs to participate in perception tasks, it is necessary to select users belonging to the same operator to minimize user privacy and security concerns. In current non-shared networks, users residing in the same cell all belong to the same operator. Therefore, when selecting UEs to participate in perception tasks, only the type of perception service, the requester's information, perception requirements, base station, and UE perception device capabilities need to be considered. However, in shared networks, users from multiple shared operators reside in the same cell simultaneously. If only the above factors are considered when selecting perception modes and UEs to participate in perception tasks, it is possible to select users from other operators, leading to unnecessary failures in the perception configuration process and wasting air interface resources.

[0069] Third, in a shared network environment, sensing tasks initiated by shared base stations may originate from one or more operators. Therefore, when initiating a sensing task, the base station needs to store the Public Land Mobile Network (PLMN) identifier of the originating operator. This ensures that the sensing results can be accurately fed back to the corresponding operator based on the PLMN identifier during subsequent reporting. This guarantees the effectiveness of the reported sensing results and avoids resource waste caused by reporting results to other operators' SF network elements.

[0070] Therefore, the shared network sensing method provided in this application fully considers the needs of sensing services and selects the target sensing mode in conjunction with these needs, so that the obtained sensing results better meet the service requirements. By determining the corresponding sensing device based on the target sensing mode and then initiating the target sensing task, the implementation process of sensing services in the shared network architecture is clearly defined, and the identified sensing devices are guaranteed to perform subsequent sensing services, ensuring the safe and effective execution of sensing services and avoiding resource waste caused by inappropriate device selection.

[0071] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0072] Figure 3 This is a schematic diagram of the architecture of a shared network awareness system provided in an embodiment of this application. Figure 3 As shown, the architecture includes: sensing device 301 and core network 302.

[0073] In some embodiments, the sensing device 301 has sensing capabilities. The sensing device 301 includes a terminal and / or an access network.

[0074] A terminal can also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, etc. Terminals can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, smart home devices, etc. The embodiments in this application do not limit this.

[0075] In some embodiments, when the terminal acts as a sensing device, it accesses the core network via the access network.

[0076] In other embodiments, the terminal has sensing capabilities. For example, the terminal can perform sensing measurements based on issued sensing tasks.

[0077] In other embodiments, the terminal has communication capabilities. For example, the terminal sends measurement data to core network 302 via the core network. Or, for example, the terminal receives messages from core network 302.

[0078] An access network can also be called an access node. An access network can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next-generation NodeB (gNB), a next-generation base station in a 6G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc. An access network can also be a macro base station, a micro base station, an indoor station, a relay node, a donor node, or a radio controller in a CRAN scenario. Furthermore, an access network can also be a server, wearable device, vehicle, or in-vehicle equipment, etc. For example, the access network in vehicle-to-everything (V2X) technology can be a roadside unit (RSU). All or part of the functions of the access network in this application embodiment can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (e.g., a cloud platform). The access network in this application can also be a logical node, logical module, or software capable of implementing all or part of the access network functions; this application embodiment does not limit this.

[0079] In some embodiments, the access network has sensing capabilities. For example, the access network can perform sensing measurements based on issued sensing tasks.

[0080] In other embodiments, the access network has communication capabilities. For example, communication between the access network and the core network 302.

[0081] The core network 302 can refer to providing service support for terminals. In this embodiment, the core network 302 includes sensing function (SF) network elements, which are mainly used to implement sensing functions, such as sensing control functions and / or sensing computing functions.

[0082] Core network 302 may also include at least one of the following: access and mobility management function (AMF) network elements, session management function (SMF) network elements, user plane function (UPF) network elements, policy control function (PCF) network elements, unified data management (UDM) network elements, application function (AF) network elements, network exposure function (NEF) network elements, and location management function (LMF) network elements. Of course, core network 302 may also include other core network equipment, which is not limited in this embodiment.

[0083] In some embodiments, the core network 302 has processing capabilities. For example, the core network 302 determines a target sensing mode corresponding to the application scenario of the target sensing task. As another example, based on the target sensing mode, the core network 302 identifies whether base stations and / or terminals contracted by the first operator within the sensing area of ​​the target sensing task can serve as sensing devices for performing the target sensing task.

[0084] The target perception mode includes any one of the following: base station self-transmission and self-reception mode, terminal self-transmission and self-reception mode, base station A transmits and base station B receives mode, base station transmits and terminal receives mode, terminal transmits and base station receives mode, and terminal A transmits and terminal B receives mode.

[0085] In other embodiments, the core network 302 has communication capabilities. For example, when the core network 302 detects the presence of a sensing device, it sends a first message to the sensing device. This first message instructs the execution of a target sensing task.

[0086] When the sensing device 301 includes a terminal and an access network, the terminal connects to the access network wirelessly. For example, the terminal and the access network can connect via an air interface. The access network connects to the core network 302 wirelessly or via a wired connection. The core network device and the access network in the core network 302 can be different physical devices, or they can be the same physical device integrating core network logical functions and wireless access network logical functions.

[0087] It should be noted that in a shared network awareness system, there are multiple core networks, each belonging to a different operator. These multiple operators' core networks are connected to a single access network.

[0088] It should be noted that the various embodiments of this application can be referenced or learned from each other. For example, the same or similar steps, method embodiments, system embodiments and device embodiments can be referenced from each other without limitation.

[0089] Figure 4 A flowchart of a shared network awareness method provided in this application embodiment Figure 1 .like Figure 4 As shown, this method can be implemented through S401 to S403.

[0090] S401. Based on the application scenario of the target perception task, determine the target perception mode corresponding to the application scenario.

[0091] The target perception mode includes any one of the following: base station self-transmission and self-reception mode, terminal self-transmission and self-reception mode, base station A transmits and base station B receives mode, base station transmits and terminal receives mode, terminal transmits and base station receives mode, and terminal A transmits and terminal B receives mode.

[0092] For example, target perception tasks include application scenarios, perception areas, and perception measurement accuracy.

[0093] For example, application scenarios for target perception tasks can include high-definition map construction, road monitoring, intrusion detection in areas surrounding high-speed railways, and drone monitoring.

[0094] S402. Based on the target perception mode, identify whether the base station and / or the terminal contracted by the first operator within the perception area of ​​the target perception task can serve as the perception device for performing the target perception task.

[0095] S403. Upon detecting the presence of a sensing device, send the first message to the sensing device.

[0096] The first message is used to instruct the execution of the target perception task.

[0097] The shared network sensing method provided in this application determines the target sensing mode based on the application scenario of the target sensing task. This fully considers the needs of sensing services and selects the target sensing mode in conjunction with these needs, ensuring that the obtained sensing results better meet business requirements. By determining the corresponding sensing device based on the target sensing mode and then initiating the target sensing task, the method clarifies the sensing service implementation process in the shared network architecture and ensures that the identified sensing devices can perform subsequent sensing services. This guarantees the safe and effective execution of sensing services and avoids resource waste caused by inappropriate device selection.

[0098] The following is a summary of the above. Figure 4The process of identifying the sensing device in step S402 will be described. In one possible implementation, the process of identifying the sensing device in step S402 includes the following three cases.

[0099] Scenario 1: When the target sensing mode is either base station self-transmitting and self-receiving mode or base station A transmitting and base station B receiving mode, identify whether the base station in the sensing area of ​​the target sensing task can be used as a sensing device to perform the target sensing task.

[0100] Scenario 2: When the target perception mode is terminal self-transmission and self-reception mode or terminal A transmits and terminal B receives mode, identify whether the terminal contracted by the first operator within the perception area of ​​the target perception task can serve as the perception device to perform the target perception task.

[0101] Scenario 3: When the target sensing mode is base station transmit / terminal receive or terminal transmit / base station receive, identify whether the base station and the terminal contracted by the first operator within the sensing area of ​​the target sensing task can serve as sensing devices to perform the target sensing task.

[0102] In this way, we can discuss the identification of the presence of sensing devices under different target sensing modes, that is, whether only the base station is involved, only the terminal is involved, or both the base station and the terminal are involved, so as to adapt to different application scenarios.

[0103] Taking Case 1 as an example, when the target sensing mode is the base station self-transmitting and self-receiving mode or the base station A transmitting and base station B receiving mode, the above process of identifying sensing devices can be achieved through the following steps 11 to 13.

[0104] Step 11: Identify whether the base station within the sensing area of ​​the target sensing task is performing a sensing task.

[0105] For example, the SF network element of the core network of the first operator sends a fifth message to the base station within the sensing area of ​​the target sensing task. The fifth message is used to confirm whether the base station is performing a sensing task. The fifth message includes a PLMN identifier.

[0106] After receiving the fifth message, the base station sends a sixth message to the core network of the first operator based on the PLMN identifier. The sixth message is used to indicate whether the base station is performing a sensing task.

[0107] After receiving the sixth message, the core network of the first operator identifies whether the base station in the sensing area of ​​the target sensing task is performing the sensing task based on the sixth message.

[0108] Step 12: If the base station in the sensing area of ​​the target sensing task does not perform the sensing task, determine that the base station in the sensing area of ​​the target sensing task can serve as a sensing device to perform the target sensing task.

[0109] If a base station within the sensing area of ​​a target sensing task does not perform a sensing task, it means that the base station can be used to perform the target sensing task, that is, the base station can be used as a sensing device.

[0110] Step 13: If a base station within the sensing area of ​​the target sensing task is performing a sensing task, then, based on the application scenario of the current sensing task and the application scenario of the target sensing task, identify whether the base station within the sensing area of ​​the target sensing task can serve as a sensing device for performing the target sensing task.

[0111] For example, when a base station is performing a sensing task within the sensing area of ​​the target sensing task, during the process of the base station sending a sixth message to the SF network element of the first operator's core network, the sixth message also includes the configuration of the sensing task being performed. For example, the application scenario, sensing measurement accuracy, and sensing area of ​​the sensing task being performed. Based on the sixth message, the SF network element of the first operator's core network determines information such as the application scenario, sensing measurement accuracy, and sensing area of ​​the sensing task being performed.

[0112] Thus, it is possible to clearly define the process of identifying the presence of sensing devices when the target sensing mode is either a base station self-transmitting and self-receiving mode or a base station A transmitting and base station B receiving mode, i.e., when only the base station is involved. The process of determining sensing devices is discussed in two cases: when the base station in the sensing area of ​​the target sensing task is performing a sensing task and when it is not performing a sensing task. This can avoid the occurrence of sensing task conflicts and avoid conflicts in the sensing process.

[0113] The process of identifying the sensing device in step 13 above will be described below. As a possible embodiment of this application, the process of identifying the sensing device in step 13 above can be implemented by steps 21 to 24.

[0114] Step 21: When the application scenario of the current sensing task and the application scenario of the target sensing task are different, determine that the base station in the sensing area of ​​the target sensing task cannot be used as the sensing device to perform the target sensing task.

[0115] When the application scenario of the current sensing task differs from that of the target sensing task, it indicates that the data that the base station needs to measure and report for the current sensing task may differ from the data that the target sensing task needs to measure and report. In other words, when the application scenarios of the current sensing task and the target sensing task are different, the base station cannot simultaneously perform sensing measurements for both sensing tasks; that is, the base station within the sensing area of ​​the target sensing task cannot act as a sensing device for performing the target sensing task.

[0116] Step 22: When the application scenarios of the current perception task and the target perception task are the same, identify the perception measurement accuracy of the current perception task and the perception measurement accuracy of the target perception task.

[0117] If the application scenario of the current perception task and the application scenario of the target perception task are the same, it indicates that the perception data that the current perception task needs to report may be the same.

[0118] Step 23: If the sensing measurement accuracy of the current sensing task is greater than or equal to the sensing measurement accuracy of the target sensing task, determine that the base station within the sensing area of ​​the target sensing task can serve as the sensing device for performing the target sensing task.

[0119] If the sensing measurement accuracy of the current sensing task is greater than or equal to the sensing measurement accuracy of the target sensing task, it means that the accuracy of the sensing data obtained from the current sensing task is sufficient to meet the accuracy requirements of the target sensing task. In other words, the sensing data from the current sensing task can be used as the sensing data for the target sensing task. This means that base stations within the sensing area of ​​the target sensing task can be used as sensing devices to perform the target sensing task.

[0120] Step 24: If the sensing measurement accuracy of the current sensing task is less than or equal to the sensing measurement accuracy of the target sensing task, determine that the base station within the sensing area of ​​the target sensing task cannot be used as a sensing device to perform the target sensing task.

[0121] If the sensing measurement accuracy of the current sensing task is lower than that of the target sensing task, it indicates that the accuracy of the sensing data obtained from the current sensing task cannot meet the accuracy requirements of the target sensing task. In other words, base stations within the sensing area of ​​the target sensing task cannot be used as sensing devices to perform the target sensing task.

[0122] Thus, by determining whether the base station in the sensing area of ​​the target sensing task is performing a sensing task, the application scenario and sensing measurement accuracy of the performing sensing task, and the application scenario and sensing measurement accuracy of the target sensing task, the sensing device can be clearly identified, thus clarifying the process of determining the sensing device under different circumstances.

[0123] Furthermore, after step 23 above, if the presence of a sensing device is detected, step S403 includes steps 31 to 32.

[0124] Step 31: Identify whether the perception area of ​​the current perception task is greater than or equal to the perception area of ​​the target perception task.

[0125] Step 32: If the sensing area of ​​the current sensing task is greater than or equal to the sensing area of ​​the target sensing task, send a first message to the base station within the sensing area of ​​the target sensing task.

[0126] If the sensing area of ​​the current sensing task is greater than or equal to the sensing area of ​​the target sensing task, it means that the sensing data obtained from the current sensing task includes the sensing data required for the target sensing task. In other words, the base station can obtain the sensing data required for the target sensing task while performing the current sensing task.

[0127] For example, when the sensing area of ​​the current sensing task is greater than or equal to the sensing area of ​​the target sensing task, the SF network element of the first operator sends a sensing result reporting modification request to the sensing device. This sensing result reporting modification request instructs the sensing device to send the sensing results to the SF network elements of the first operator's core network and the SF network elements of the second operator's core network. The second operator's core network is the core network that is currently executing the sensing task.

[0128] Understandably, for base stations within the sensing area where data is being used for a sensing task, but not within the sensing area of ​​the target sensing task, it is only necessary to send the sensing results to the SF network element of the second operator's core network.

[0129] Thus, when the sensing area of ​​the current sensing task is greater than or equal to the sensing area of ​​the target sensing task, sending the first message directly to the sensing device allows for direct sensing using existing resources, avoiding secondary execution and thus avoiding resource waste.

[0130] Furthermore, after step 24 above, if the presence of a sensing device is detected, step S403 includes steps 41 to 42.

[0131] Step 41: Identify whether the perception area of ​​the current perception task is greater than or equal to the perception area of ​​the target perception task.

[0132] Step 42: If the sensing area of ​​the current sensing task is smaller than the sensing area of ​​the target sensing task, send the first message to the base station within the sensing area of ​​the target sensing task.

[0133] If the sensing area of ​​the current sensing task is smaller than the sensing area of ​​the target sensing task, it indicates that the sensing data obtained from the current sensing task is only a portion of the sensing data required for the target sensing task. That is, during the execution of the current sensing task by this base station, only a portion of the sensing data required for the target sensing task can be obtained. The target sensing task is initiated by sending a first message to a base station within the sensing area of ​​the target sensing task.

[0134] Thus, when the sensing area of ​​the sensing task being performed is smaller than the sensing area of ​​the target sensing task, the base stations in the sensing area of ​​the target sensing task send the sensing results to the SF network element of the core network of the first operator by sending a first message to the base stations in the sensing area of ​​the target sensing task.

[0135] In addition, after step 42, the method further includes steps 51 to 53.

[0136] Step 51: Divide the base stations within the perception area of ​​the target perception task into a first sub-base station set and a second sub-base station set.

[0137] Among them, the base stations in the first sub-base station group are base stations that only perform target perception tasks, and the base stations in the second sub-base station group are base stations that perform target perception tasks and base stations that are currently performing perception tasks.

[0138] For example, the base stations within the sensing area of ​​the target sensing task are divided according to the sensing area of ​​the sensing task currently being performed and the sensing area of ​​the target sensing task.

[0139] Step 52: Send the second message to the base stations in the first sub-base station set.

[0140] The second message is used to instruct the base stations in the first sub-base station cluster to send the sensing results to the core network of the first operator.

[0141] Step 53: Send a third message to the base stations in the second sub-base station set.

[0142] The third message is used to instruct the base stations in the second sub-base station cluster to send the sensing results to the core network of the first operator and the core network of the second operator. The core network of the second operator is the core network that is currently performing the sensing task.

[0143] Thus, when the sensing area of ​​the sensing task being performed is smaller than the sensing area of ​​the target sensing task, it is possible to determine which core network SF elements the base station in the sensing area of ​​the target sensing task needs to send sensing results to, thereby avoiding the base station sending sensing results to the core network that has not issued sensing tasks and avoiding resource waste.

[0144] Figure 5 A flowchart of a shared network awareness method provided in this application embodiment Figure 2 .like Figure 5 As shown, the method includes the following steps.

[0145] S501. The SF network element of the core network of the first operator determines whether the target sensing mode is the base station self-transmitting and self-receiving mode or the base station A transmitting and base station B receiving mode. If so, then execute S502.

[0146] S502. The SF network element of the first operator's core network determines whether it stores the sensing capability information of the base stations within the sensing area of ​​the target sensing task. If yes, proceed to S503; otherwise, proceed to S517.

[0147] S503, the SF network element of the core network of the first operator sends the fifth message to the base station within the sensing area of ​​the target sensing task.

[0148] The fifth message is used to confirm whether the base station is performing a sensing task. The fifth message includes the PLMN identifier.

[0149] S504. The base station within the sensing area of ​​the target sensing task sends the sixth message to the SF network element of the core network of the first operator based on the PLMN identifier.

[0150] The sixth message indicates whether a perception task is being performed. If a perception task is being performed, the sixth message also includes the configuration for performing the perception task.

[0151] S505: The SF network element of the core network of the first operator determines, based on the sixth message, whether the base station within the sensing area of ​​the target sensing task is performing a sensing task. If not, proceed to S506; if yes, proceed to S507.

[0152] S506. When the base station in the sensing area of ​​the target sensing task is not performing the sensing task, the SF network element of the core network of the first operator determines that the base station in the sensing area of ​​the target sensing task can be used as a sensing device to perform the target sensing task.

[0153] After step S506, step S513 is executed.

[0154] S507. If a base station within the sensing area of ​​the target sensing task is performing a sensing task, the SF network element of the first operator's core network determines whether the application scenario of the currently performing sensing task is the same as the application scenario of the target sensing task. If not, proceed to S508; if yes, proceed to S509.

[0155] S508. When the application scenario of the core network element of the first operator is performing a sensing task and the application scenario of the target sensing task are different, the base station in the sensing area of ​​the target sensing task cannot be used as a sensing device to perform the target sensing task.

[0156] S509. When the application scenario of the current sensing task and the application scenario of the target sensing task are the same, the SF network element of the core network of the first operator determines whether the sensing measurement accuracy of the current sensing task is greater than or equal to the sensing measurement accuracy of the target sensing task. If not, proceed to S510; if yes, proceed to S511.

[0157] S510, if the sensing measurement accuracy of the core network element of the first operator is less than or equal to the sensing measurement accuracy of the target sensing task, the base station in the sensing area of ​​the target sensing task cannot be used as a sensing device to perform the target sensing task.

[0158] S511. When the sensing measurement accuracy of the core network element of the first operator is greater than or equal to the sensing measurement accuracy of the target sensing task, the base station in the sensing area of ​​the target sensing task can be used as a sensing device to perform the target sensing task.

[0159] S512. The SF network element of the core network of the first operator determines whether the sensing area of ​​the sensing task being performed is greater than or equal to the sensing area of ​​the target sensing task. If yes, then execute S513; if no, then execute S515.

[0160] S513, the SF network element of the core network of the first operator sends the fourth message to the sensing device.

[0161] The fourth message includes the perception measurement configuration information for the target perception task.

[0162] S514, the SF network element of the core network of the first operator sends the first message to the sensing device.

[0163] The first message is used to instruct the execution of the target perception task.

[0164] It should be noted that there is no strict order between steps S513 and S514. Step S513 can be executed first, followed by step S514; or step S514 can be executed first, followed by step S513; or steps S513 and S514 can be executed simultaneously. This application embodiment does not limit this.

[0165] S515. When the sensing area of ​​the core network of the first operator is smaller than the sensing area of ​​the target sensing task, the SF network element divides the base stations in the sensing area of ​​the target sensing task into a first sub-base station set and a second sub-base station set.

[0166] S516, the SF network element of the core network of the first operator sends a second message to the base station in the first sub-base station set, and sends a third message to the base station in the second sub-base station set.

[0167] The second message instructs the base stations in the first sub-base station cluster to send the sensing results to the core network of the first operator. The third message instructs the base stations in the second sub-base station cluster to send the sensing results to the core networks of both the first and second operators, where the core network of the second operator is the core network currently executing the sensing task.

[0168] Step S513 is executed after step S516.

[0169] S517. The SF network element of the core network of the first operator sends a base station perception capability reporting request to the base station in the perception area of ​​the target perception task.

[0170] The base station sensing capability reporting request is used to request the base station to report its sensing capability information. For example, sensing capability information includes the base station's sensing range, sensing type, sensing parameters, and sensing performance.

[0171] S518. Base stations within the sensing area of ​​the target sensing task send base station sensing capability information to the SF network element of the core network of the first operator based on the base station sensing capability reporting request.

[0172] After step S518 above, step S503 is executed.

[0173] Taking Case 2 as an example, when the target sensing mode is the terminal self-transmitting and self-receiving mode or the terminal A transmitting and terminal B receiving mode, the above process of identifying sensing devices can be implemented through the following steps 61 to 63.

[0174] Step 61: Identify whether the terminals contracted by the first operator within the perception area of ​​the target perception task meet the first terminal perception measurement conditions.

[0175] The first terminal sensing measurement conditions include: terminals subscribed to by the first operator within the sensing area of ​​the target sensing task are subscribed to sensing services; terminals subscribed to by the first operator within the sensing area of ​​the target sensing task are not performing sensing tasks; terminals subscribed to by the first operator within the sensing area of ​​the target sensing task have the capability of self-transmitting and self-receiving mode or terminal A transmitting and terminal B receiving mode; and the sensing measurement accuracy of terminals subscribed to by the first operator within the sensing area of ​​the target sensing task is greater than or equal to the sensing measurement accuracy of the target sensing task.

[0176] For example, the SF network element of the core network of the first operator sends a terminal capability reporting request to the terminals subscribed to by the first operator within the sensing area of ​​the target sensing task. This terminal capability reporting request is used to request the terminals to report sensing-related information, such as whether they have subscribed to a sensing service, whether they are currently performing a sensing task, their sensing mode capabilities, and the accuracy of their sensing measurements.

[0177] For example, the SF network element of the core network of the first operator can first send a terminal capability reporting request to the base station. This request includes a PLMN identifier. Based on this PLMN identifier, the base station sends the terminal capability reporting request to all terminals subscribed to by the first operator within the sensing area of ​​the target sensing task.

[0178] Terminals within the target sensing task's sensing area that are subscribed to by the first operator send a terminal capability reporting response to the SF network element of the first operator's core network. The terminal capability reporting response includes sensing-related information, such as whether it has subscribed to a sensing service, whether it is currently performing a sensing task, its sensing mode capabilities, and the accuracy of its sensing measurements. Based on the terminal capability reporting response, the SF network element of the first operator's core network determines whether the terminal meets the first terminal sensing measurement conditions.

[0179] Understandably, the terminal contracted by the first operator within the perception area of ​​the target perception task is a terminal in a connected state.

[0180] Step 62: If the terminal contracted by the first operator within the sensing area of ​​the target sensing task meets the first terminal sensing measurement conditions, the terminal contracted by the first operator within the sensing area of ​​the target sensing task can serve as a sensing device for performing the target sensing task.

[0181] If a terminal contracted by the first operator within the sensing area of ​​the target sensing task meets the first terminal sensing measurement conditions, it indicates that the terminal has the capability to perform sensing. Furthermore, the terminal belongs to the first operator, avoiding the problem of using terminals from other operators as sensing devices and thus infringing on user privacy, as well as the problem of subsequent sensing task execution failure due to using terminals from other operators as sensing devices, thereby avoiding the waste of air interface resources.

[0182] Step 63: If the terminal contracted by the first operator within the sensing area of ​​the target sensing task does not meet the first terminal sensing measurement conditions, the terminal contracted by the first operator within the sensing area of ​​the target sensing task cannot be used as a sensing device to perform the target sensing task.

[0183] If the terminal contracted by the first operator within the sensing area of ​​the target sensing task does not meet the first terminal sensing measurement conditions, it indicates that the terminal does not meet the conditions to be a sensing device. By screening the terminals in advance, the problem of sensing task execution failure due to terminal selection can be avoided.

[0184] Figure 6 A flowchart of a shared network awareness method provided in this application embodiment Figure 3 .like Figure 6 As shown, the method includes the following steps.

[0185] S601. The SF network element of the core network of the first operator determines whether the target sensing mode is the terminal self-transmitting and self-receiving mode or the terminal A transmitting and terminal B receiving mode. If so, then execute S602.

[0186] S602, the SF network element of the core network of the first operator sends a terminal capability reporting request to the terminal contracted by the first operator within the sensing area of ​​the target sensing task.

[0187] S603. The terminal contracted by the first operator within the sensing area of ​​the target sensing task sends a terminal capability reporting response to the SF network element of the core network of the first operator.

[0188] S604. The SF network element of the core network of the first operator, based on the terminal capability reporting response, determines whether the terminal contracted by the first operator within the sensing area of ​​the target sensing task meets the first terminal sensing measurement conditions. If yes, then execute S605; if no, then execute S608.

[0189] S605. If the SF network element of the core network of the first operator meets the first terminal sensing measurement conditions within the sensing area of ​​the target sensing task, the first operator's contracted terminal within the sensing area of ​​the target sensing task can be used as a sensing device to perform the target sensing task.

[0190] S606, the SF network element of the core network of the first operator sends the fourth message to the sensing device.

[0191] The fourth message includes the perception measurement configuration information for the target perception task.

[0192] S607, the SF network element of the core network of the first operator sends the first message to the sensing device.

[0193] The first message is used to instruct the execution of the target perception task.

[0194] It should be noted that there is no strict order between steps S606 and S607. Step S606 can be executed first, followed by step S607; or step S607 can be executed first, followed by step S606; or steps S606 and S607 can be executed simultaneously. This application embodiment does not limit this.

[0195] S608. If the terminal contracted by the first operator within the sensing area of ​​the first operator's core network does not meet the first terminal sensing measurement conditions, the terminal contracted by the first operator within the sensing area of ​​the target sensing task cannot be used as a sensing device to perform the target sensing task.

[0196] Taking case three as an example, when the target sensing mode is base station transmit terminal receive mode or terminal transmit base station receive mode, the above process of identifying sensing devices can be implemented through the following steps 71 to 75.

[0197] Step 71: Identify whether the terminals contracted by the first operator within the perception area of ​​the target perception task meet the second terminal perception measurement conditions.

[0198] The second terminal sensing measurement conditions include: the terminal signed by the first operator within the sensing area of ​​the target sensing task is subscribed to sensing services; the terminal signed by the first operator within the sensing area of ​​the target sensing task is not performing a sensing task; the terminal signed by the first operator within the sensing area of ​​the target sensing task has the capability of base station transmit / receive mode or terminal transmit / receive mode; and the sensing measurement accuracy of the terminal signed by the first operator within the sensing area of ​​the target sensing task is greater than or equal to the sensing measurement accuracy of the target sensing task.

[0199] For example, the SF network element of the core network of the first operator sends a terminal capability reporting request to the terminals subscribed to by the first operator within the sensing area of ​​the target sensing task. This terminal capability reporting request is used to request the terminals to report sensing-related information, such as whether they have subscribed to a sensing service, whether they are currently performing a sensing task, their sensing mode capabilities, and the accuracy of their sensing measurements.

[0200] For example, the SF network element of the core network of the first operator can first send a terminal capability reporting request to the base station. This request includes a PLMN identifier. Based on this PLMN identifier, the base station sends the terminal capability reporting request to all terminals subscribed to by the first operator within the sensing area of ​​the target sensing task.

[0201] Terminals within the target sensing task's sensing area that are subscribed to by the first operator send a terminal capability reporting response to the SF network element of the first operator's core network. The terminal capability reporting response includes sensing-related information, such as whether it has subscribed to a sensing service, whether it is currently performing a sensing task, its sensing mode capabilities, and the accuracy of its sensing measurements. Based on the terminal capability reporting response, the SF network element of the first operator's core network determines whether the terminal meets the second terminal sensing measurement conditions.

[0202] Understandably, the terminal contracted by the first operator within the perception area of ​​the target perception task is a terminal in a connected state.

[0203] Step 72: If the terminal contracted by the first operator within the sensing area of ​​the target sensing task does not meet the sensing measurement conditions of the second terminal, determine that the base station and the terminal contracted by the first operator within the sensing area of ​​the target sensing task cannot be used as sensing devices to perform the target sensing task.

[0204] In a sensing mode that requires the joint participation of terminals and base stations, if the terminal contracted by the first operator in the sensing area of ​​the target sensing task does not meet the sensing measurement conditions of the second terminal, it indicates that the terminal does not have the capability to act as a sensing device, that is, it cannot complete the sensing measurement in the base station transmit-terminal receive mode or the terminal transmit-base station receive mode.

[0205] Step 73: If the terminal of the first operator in the sensing area of ​​the target sensing task meets the sensing measurement conditions of the second terminal, identify whether the base station in the sensing area of ​​the target sensing task is performing a sensing task.

[0206] In a sensing mode that requires the joint participation of terminals and base stations, when the terminal of the first operator in the sensing area of ​​the target sensing task meets the sensing measurement conditions of the second terminal, it indicates that there is a terminal that can act as a sensing device. The sensing device is then further confirmed based on whether the base station performs the sensing task.

[0207] Step 74: If a base station within the sensing area of ​​the target sensing task is performing a sensing task, determine that the base station within the sensing area of ​​the target sensing task and the terminal contracted by the first operator cannot be used as sensing devices to perform the target sensing task.

[0208] When a base station within the sensing area of ​​the target sensing task is performing a sensing task, it is determined that the base station and the terminal contracted by the first operator within the sensing area of ​​the target sensing task cannot be used as sensing devices to perform the target sensing task. This precondition screening avoids the problem of sensing task conflicts in the base station.

[0209] Step 75: If the base station in the sensing area of ​​the target sensing task does not perform the sensing task, determine that the base station in the sensing area of ​​the target sensing task and the terminal contracted by the first operator can serve as sensing devices to perform the target sensing task.

[0210] This not only avoids the problem of conflicting perception tasks, but also makes full use of existing resources to perform perception measurements and obtain the results required by the user.

[0211] Figure 7 A flowchart of a shared network awareness method provided in this application embodiment Figure 4 .like Figure 7 As shown, the method includes the following steps.

[0212] S701. The SF network element of the core network of the first operator determines whether the target sensing mode is base station transmit / terminal receive mode or terminal transmit / base station receive mode. If so, then execute S702.

[0214] S703. The terminal contracted by the first operator within the sensing area of ​​the target perception task sends a terminal capability reporting response to the SF network element of the core network of the first operator.

[0215] S704. The SF network element of the core network of the first operator reports a response based on the terminal capability to determine whether the terminal contracted by the first operator within the sensing area of ​​the target sensing task meets the second terminal sensing measurement conditions. If not, proceed to S705; if yes, proceed to S706.

[0216] S705. If the SF network element of the core network of the first operator does not meet the second terminal sensing measurement conditions of the terminal contracted by the first operator within the sensing area of ​​the target sensing task, it is determined that the base station and the terminal contracted by the first operator within the sensing area of ​​the target sensing task cannot be used as sensing devices to perform the target sensing task.

[0217] S706. If the SF network element of the first operator's core network meets the second terminal sensing measurement conditions within the sensing area of ​​the target sensing task, it determines whether the SF network element of the first operator's core network stores the sensing capability information of the base stations within the sensing area of ​​the target sensing task. If yes, proceed to S707; otherwise, proceed to S714.

[0218] S707, the SF network element of the core network of the first operator sends the fifth message to the base station within the sensing area of ​​the target sensing task.

[0219] The fifth message is used to confirm whether the base station is performing a sensing task. The fifth message includes the PLMN identifier.

[0220] S708, The base station within the sensing area of ​​the target sensing task sends the sixth message to the SF network element of the core network of the first operator based on the PLMN identifier.

[0221] The sixth message indicates whether a perception task is being performed. If a perception task is being performed, the sixth message also includes the configuration for performing the perception task.

[0222] S709: The SF network element of the core network of the first operator determines, based on the sixth message, whether the base station within the sensing area of ​​the target sensing task is performing a sensing task. If yes, then execute S710; otherwise, execute S711.

[0223] S710. When the SF network element of the core network of the first operator is performing a sensing task within the sensing area of ​​the target sensing task, it determines that the base station and the terminal contracted by the first operator within the sensing area of ​​the target sensing task cannot be used as sensing devices to perform the target sensing task.

[0224] S711. When the base station in the sensing area of ​​the first operator's core network does not perform the sensing task, the SF network element determines that the base station in the sensing area of ​​the target sensing task and the terminal contracted by the first operator can serve as sensing devices to perform the target sensing task.

[0225] S712, the SF network element of the core network of the first operator sends the fourth message to the sensing device.

[0226] The fourth message includes the perception measurement configuration information for the target perception task.

[0227] S713, the SF network element of the core network of the first operator sends the first message to the sensing device.

[0228] The first message is used to instruct the execution of the target perception task.

[0229] It should be noted that there is no strict order between steps S712 and S713. Step S712 can be executed first, followed by step S713; or step S713 can be executed first, followed by step S712; or steps S712 and S713 can be executed simultaneously. This application embodiment does not limit this.

[0230] S714. The SF network element of the core network of the first operator sends a base station perception capability reporting request to the base station in the perception area of ​​the target perception task.

[0231] The base station sensing capability reporting request is used to request the base station to report its sensing capability information. For example, sensing capability information includes the base station's sensing range, sensing type, sensing parameters, and sensing performance.

[0232] S715. Base stations within the sensing area of ​​the target sensing task send base station sensing capability information to the SF network element of the core network of the first operator based on the base station sensing capability reporting request.

[0233] After step S715 above, step S707 is executed.

[0234] In addition, after steps 12, 42, 63, and 75, the above method further includes sending a fourth message to the sensing device.

[0235] The fourth message includes sensing measurement configuration information.

[0236] For example, the sensing measurement configuration information includes information such as time domain resource configuration, spatial domain resource configuration, code domain resource configuration, sensing measurement area, and sensing measurement accuracy.

[0237] Thus, after identifying the sensing device, a fourth message is sent to the sensing device, enabling the sensing device to identify the sensing measurement configuration message and then perform sensing measurement based on the sensing measurement configuration information.

[0238] The following is a summary of the above. Figure 4 The process of determining the target perception mode in step S401 will be described below. As a possible embodiment of this application, the process of determining the target perception mode in step S401 can be implemented by steps 81 to 82.

[0239] Step 81: Based on the mapping relationship between application scenarios and perception modes, and the execution priority of perception modes, determine at least one perception mode corresponding to the application scenario and the execution priority corresponding to the perception mode.

[0240] For example, Table 1 is a mapping table of application scenarios and perception modes, and the execution priority of perception modes, provided in an embodiment of this application.

[0241] Table 1

[0242] When the execution priority of the perception mode is 1, it indicates that the execution priority is the highest.

[0243] For example, Table 1 above is stored in the SF network element. Table 1 above is only an example, and individual operators can adjust it according to their own sensing service development needs, their own network sensing capabilities, etc., and reconfigure the mapping relationship between application scenarios and sensing modes, and the execution priority of sensing modes according to their own needs.

[0244] Step 82: In at least one perception mode, determine the perception mode with the highest execution priority as the target perception mode.

[0245] Thus, by mapping the application scenario to the perception mode and the execution priority of the perception mode, the process of determining the target perception mode can be clearly defined.

[0246] In addition, when there are multiple perception modes corresponding to the application scenario, the above method also includes the following step one.

[0247] Step 1: If no sensing device is detected, the highest priority sensing mode will be executed from the unselected sensing modes, and the target sensing mode will be redefined.

[0248] Taking the application scenario of "high-definition map construction" as an example, the corresponding sensing modes for this application scenario include base station self-transmission and self-reception mode, terminal self-transmission and self-reception mode, base station A transmits and B receives mode, and terminal A transmits and B receives mode. The execution priority, from high to low, is: base station self-transmission and self-reception mode, terminal self-transmission and self-reception mode, base station A transmits and B receives mode, and terminal A transmits and B receives mode. When no sensing device exists in the base station self-transmission and self-reception mode, the terminal self-transmission and self-reception mode is used as the target sensing mode. And so on, which will not be elaborated further here.

[0249] In this way, it becomes clear how to determine the target perception mode when there are multiple perception modes corresponding to the application scenario and no perception device is available.

[0250] Taking "high-definition map construction" as an example, Figure 8 A flowchart of a shared network awareness method provided in this application embodiment Figure 5 .like Figure 8 As shown, the method includes the following steps.

[0251] S801. After receiving the target perception task sent by the AF network element, the SF network element of the core network of the first operator determines at least one perception mode corresponding to the application scenario and the execution priority of the perception mode based on the mapping relationship between the application scenario and the perception mode and the execution priority of the perception mode.

[0252] The number of perception modes N max Configured to the lowest execution priority, i.e., N. max =4.

[0253] S802. In the first operator's core network SF network element, if the sensing mode has not been selected, the highest priority sensing mode will be executed and determined as the target sensing mode.

[0254] The target perception mode parameter N sensing_mode_priority Set to the value corresponding to the highest execution priority among the unselected perception modes.

[0255] S803. The SF network element of the core network of the first operator, based on the target perception mode, identifies whether the base stations and / or terminals contracted by the first operator within the perception area of ​​the target perception task can serve as perception devices to perform the target perception task. If yes, then proceed to S804; if no, then proceed to S806.

[0256] S804. Upon detecting the presence of a sensing device, send the first message to the sensing device.

[0257] S805, the SF network element of the first operator's core network sends a target perception task start success message to the AF network element of the first operator's core network.

[0258] In addition, upon detecting the presence of a sensing device, a first message is sent to the sensing device. After performing sensing measurements, the sensing device sends the sensing results to the SF network element of the core network of the first operator.

[0259] For example, when the sensing device is a terminal, the terminal sends the sensing results to the base station, and the base station sends the sensing results to the SF network element of the first operator's core network based on the PLMN identifier. When the sensing device is a base station, the base station sends the sensing results to the SF network element of the first operator's core network based on the PLMN identifier.

[0260] S806. The SF network element of the core network of the first operator determines whether the target sensing mode parameter is less than or equal to the number of sensing modes. If yes, then execute S802; if no, then execute S807.

[0261] That is, determine N sensing_mode_priority Is it less than or equal to N? max .

[0262] S807, the SF network element of the first operator's core network sends a target perception task start failure message to the AF network element of the first operator's core network.

[0263] This application embodiment can divide the shared network sensing device into functional modules or functional units according to the above method examples. For example, each function can be divided into a separate functional module or functional unit, or two or more functions can be integrated into one processing module. The integrated module can be implemented in hardware or in software functional modules or functional units.
