[0057] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0058] FIG2 is a schematic diagram of a system architecture based on a reference point presentation method provided in an embodiment of the present application. As shown in FIG2 , the reference point presentation method can indicate that there can be interaction between corresponding network function (NF) services. Network functions include, for example, access and mobility management function (AMF) 201, session management function (SMF) 202, policy control function (PCF) 203, application function (AF) 204, user plane function (UPF) 205, network slice selection function (NSSF) 206, authentication server function (AUSF) 207, and unified data management (UDM) 208. The system may also include: UE 209, radio access network (RAN) or access point (AN) 210, and data network (DN) 211.

[0059] Figure 2 shows the following reference points: N1 (between UE 209 and AMF 201), N2 (between RAN 210 and AMF 201), N3 (between RAN 210 and UPF 205), N4 (between SMF 202 and UPF 205), N5 (between PCF 203 and AF 204), N6 (between UPF 205 and DN 211), N7 (between SMF 202 and PCF 203), N8 (between UDM 208 and AMF 201), N9 (between two UPFs 205), N10 (between UDM 208 and SMF 202), N11 (between AMF 201 and SMF 202), N12 (between AUSF 207 and AMF 201), N13 (between AUSF 207 and UDM 208), N14 (between two AMFs 201), N15 (between PCF 203 and AMF 201 in the case of non-roaming scenario, or between PCF 203 and visited network and AMF 201 in the case of roaming scenario), N16 (between two SMFs; not shown) and N22 (between AMF 201 and NSSF 206).

[0060] The following describes SMF, PCF, and AF:

[0061] SMF: includes session establishment, modification and release, tunnel maintenance between UPF and AN nodes, terminal Internet Protocol (IP) address allocation and management, selection and control of UPF functions, billing data collection and billing interface support, etc.

[0062] PCF: Supports a unified policy framework to manage network behavior and provides operator network control policies to other network elements and terminals.

[0063] AF: This can be an internal carrier application, such as the IP Multimedia Subsystem (IMS), or a third-party service, such as web services, videos, or games. If the carrier's internal AF is in the same trusted domain as other NFs, it can interact directly with other NFs. If the AF is not in a trusted domain, it requires the network exposure function (NEF) to access other NFs.

[0064] The UE establishes an access layer connection with the AN through the Uu port, exchanging access layer messages and wireless data transmission. The UE establishes a non-access stratum (NAS) connection with the AMF through the N1 port, exchanging NAS messages. The AMF is the mobility management function in the core network, and the SMF is the session management function in the core network. In addition to managing the mobility of the UE, the AMF is also responsible for forwarding session management-related messages between the UE and the SMF. The PCF is the policy management function in the core network, responsible for formulating policies related to the mobility management, session management, and billing of the UE. The UPF is the user plane function in the core network, which transmits data with the external data network through the N6 interface and with the AN through the N3 interface.

[0065] Networks in related technologies, such as 5G and other cellular networks, are used solely for communication. However, the radio electromagnetic wave signals used by cellular networks can be used not only for wireless data transmission and communication but also for environmental perception, such as user motion or gesture recognition, respiratory monitoring, terminal movement speed measurement, environmental imaging, and weather monitoring. Therefore, cellular networks can be considered not only for communication and data transmission, but also for acquiring sensory information.

[0066] Beyond 5th Generation (B5G) or later networks may support sensing capabilities by adding sensing network elements (Sensing Function) and corresponding processes to support sensing functions in 3rd Generation Partnership Project (3GPP) networks. Optionally, the sensing network elements may include Sensing Function (SF) network elements.

[0067] Optionally, in any embodiment of the present application, SF network element, SF, and SF entity may be understood synonymously. Optionally, in any embodiment of the present application, AMF network element, AMF, and AMF entity may be understood synonymously.

[0068] FIG3 is a flow chart of a sensing operation method provided in an embodiment of the present application. As shown in FIG3 , the method includes:

[0069] S301. AF sends a sensing request to SF.

[0070] Optionally, the sensing request may include: a first target area and a sensing type. Optionally, the AF may send the sensing request to the SF via the NEF.

[0071] S302. SF sends a first perception instruction to the mobility management network element.

[0072] Optionally, the first perception instruction may include: a second target area and a perception type. Optionally, the mobility management network element may include an AMF.

[0073] S303: The mobility management network element determines a perception node.

[0074] Optionally, the mobility management network element may determine a perception node based on the second target area and / or the perception type. Optionally, the perception node may include a perception access network device and / or a perception terminal device. Optionally, the perception access network device may be the aforementioned access network device. Optionally, the perception terminal device may be the aforementioned terminal device.

[0075] S304. The mobility management network element sends a second sensing instruction to the sensing node.

[0076] Optionally, the second perception instruction includes a third target area and / or perception type.

[0077] S305: The perception node determines an auxiliary node.

[0078] Optionally, the auxiliary node may include an auxiliary terminal device and / or an auxiliary access network device. Optionally, the auxiliary terminal device may be the aforementioned terminal device. Optionally, the auxiliary access network device may be the aforementioned access network device.

[0079] S306: The sensing node and / or the auxiliary node may perform access layer signal measurement.

[0080] Optionally, the access layer signal may include a reference signal. Optionally, in any embodiment of the present application, the reference signal may include at least one of the following: a reference signal between access network devices, an uplink reference signal, a downlink reference signal, and a sidelink reference signal. In some embodiments, the uplink reference signal includes at least one of the following: a sounding reference signal (SRS), a demodulation reference signal (DMRS), and a phase tracking reference signal (PTRS). In some embodiments, the downlink reference signal includes at least one of the following: a channel state information reference signal (CSI-RS), a demodulation reference signal (DMRS), and a cell-specific reference signal (CRS).

[0081] S307: The sensing node obtains sensing data.

[0082] In the embodiment corresponding to Figure 3, when the application (corresponding to the above-mentioned AF) sends a perception request for the target UE / object (corresponding to the above-mentioned perceived object) to the core network of the 3GPP network, the core network selects a perception node through the perception function network element or the access and mobility management function (Access and Mobility Management Function, AMF), and triggers the perception node to enable the perception-related wireless measurement capability, so that the perception node starts measuring the perception information and generates a perception result (i.e., the above-mentioned perception data).

[0083] The main wireless sensing scenarios for synaesthesia integration include at least one of the following:

[0084] 1) Access network device echo sensing link: The access network device sends a sensing signal and receives an echo signal;

[0085] 2) Perception link between access network devices: Access network device B receives the perception signal sent by access network device A;

[0086] 3) Air interface uplink sensing link: The access network device receives the sensing signal sent by the terminal device;

[0087] 4) Air interface downlink perception link: The terminal device receives the perception signal sent by the access network device;

[0088] 5) Terminal device echo sensing link: The terminal device sends a sensing signal and receives an echo signal;

[0089] 6) Perception link between terminal devices: Terminal device B receives the perception signal sent by terminal device A.

[0090] The communication method in the embodiment of the present application can be applied to any one or more scenarios listed above for synaesthesia integration. In B5G communication and perception integration, it is possible to consider performing perception behavior using the air interface signals specified in the multiplexing protocol.

[0091] The embodiment corresponding to Figure 3 provides a process for per-area perception. For per-area perception, the perception target is a specific area or object, which is not part of 3GPP and does not involve a specific UE, and is "passive perception."

[0092] If the perception target is regional-level perception (or passive perception), it is necessary to find a suitable perception node for the target area. For perception scenarios involving only access network devices (such as access network device echo perception and inter-access network device perception), the perception node selection process requires searching for perception nodes around the target area. Currently, it is assumed that the perception function / AMF network element knows the location of all perception nodes, and the SF / AMF directly selects a suitable perception node in or near the target area. However, there may be multiple perception nodes with signal coverage for the target area, and there has been no specific discussion on how to select the appropriate perception node to issue the perception task.

[0093] For area-level sensing scenarios, the Sensing Function (SF) / AMF element in the core network equipment is responsible for selecting appropriate gNBs / UEs around the target area as sensing nodes. However, prior art has not yet explored how the SF and AMF select gNBs / UEs when they discover multiple gNBs / UEs capable of sensing a given area.

[0094] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0268] The following uses the core network device including SF as an example to provide three embodiments to illustrate this application:

[0269] Embodiment 1: The SF first issues a sensing task to multiple RAN / UE nodes and then makes further selections based on the feedback results. Optionally, after the SF receives a sensing request (corresponding to the first sensing request described above) and discovers multiple RAN / UE nodes (corresponding to the at least one sensing node described above), it first generates a one-time sensing subtask based on the sensing request, issues it to all RAN / UE nodes that may execute the task, and then selects a UE / RAN based on the reported results of the sensing subtask.

[0270] FIG9 is a flow chart of a communication method provided in another embodiment of the present application. As shown in FIG9 , the method includes:

[0271] S901. Consumer NF sends a perception request to SF (corresponding to the first perception request mentioned above).

[0272] Optionally, the perception request may include at least one of the following: area information (corresponding to the second area information in the above embodiment), requested perception mode (corresponding to the above first perception mode), perception service type (corresponding to the above first perception service type), and perception service requirement (corresponding to the above first perception service requirement).

[0273] Optionally, the format of the region information may be different from the format stored in the SF / the format supported by the SF. Optionally, the SF may locally implement the change in the format of the region information, and then select a corresponding sensing node (a sensing node includes a RAN device or a terminal device) based on the region information after the change in format (i.e., the region information in the format stored in the SF / the format supported by the SF). Optionally, the SF may query other network elements (e.g., the second network element corresponding to the above embodiment) to obtain the region information after the change in format, and then select a corresponding sensing node based on the region information after the change in format.

[0274] Optionally, the area information in a format stored in the SF or in a format supported by the SF includes at least one of the following: (1) reference point coordinates and radius; (2) reference point coordinates, area length, and area width; (3) one or more area identifiers (Zone IDs); and (4) 3GPP area identifiers. Optionally, the 3GPP area identifier may include a cell identifier (Cell ID) and / or a tracking area identifier (Tracking Area ID).

[0275] S902. The SF determines the corresponding perception node (corresponding to the at least one perception node mentioned above, where a perception node includes a RAN device or a terminal device) according to the perception request sent by the Consumer NF.

[0276] Optionally, the SF may discover the corresponding sensing node by querying other network elements (such as the third network element mentioned above), which may include one of the following: AMF, UDR, UDM. Optionally, the SF may discover the corresponding sensing node by querying local information.

[0277] Optionally, the at least one discovered sensing node can perform sensing services for the area information corresponding to the sensing request. For example, each sensing device in the at least one sensing node can independently cover the target area, or at least two sensing nodes in the at least one sensing node can jointly cover the target area.

[0278] S903. SF generates a perception sub-request (corresponding to the second perception request in the above embodiment) based on the perception request.

[0279] Optionally, the perception sub-request can be used to preliminarily perceive the target area and select the node that will ultimately perform the perception task.

[0280] Optionally, a perception sub-request may use the same perception method as the perception request. The perception target area should be the area information included in the perception request or a subset of the area information included in the perception request. The perception duration and / or reporting frequency of the perception sub-request should be lower than the perception duration and / or reporting frequency of the perception request. For example, if the perception request requires a measurement duration of 100 seconds and a reporting frequency of 1 time / s, the perception sub-request may require a single measurement and a direct report of the result, or a 10-second measurement and two result reports.

[0281] S904. SF sends the sensing sub-request to all discovered sensing nodes that can execute the sensing task (corresponding to the at least one sensing node mentioned above).

[0282] Optionally, in any embodiment of the present application, the communication between the SF and the perception node may be direct communication, or the communication between the SF and the perception node may be through AMF communication.

[0283] S905. The sensing node performs the sensing task according to the sensing sub-request.

[0284] S906. The perception node reports the execution result corresponding to the perception sub-request to the SF.

[0285] Optionally, the execution result may include perception data information or first perception information.

[0286] S907. SF selects a perception node based on the execution result corresponding to the perception sub-request.

[0287] Optionally, in S907, the selected sensing node may correspond to one or more sensing nodes in the above-mentioned embodiment. Optionally, the execution result corresponding to the sensing sub-request may include at least one of the following: target location information, point cloud information, accuracy information, channel quality information between the target area, etc.

[0288] S908. SF sends a perception request (corresponding to the second perception request mentioned above) to the selected perception node.

[0289] In related technologies, for regional-level perception, there may be many available perception nodes (i.e., at least one of the above-mentioned perception nodes) that can be used to perform perception tasks. If the perception tasks are distributed to all perception nodes, it may cause a waste of resources (some nodes with poor performance waste perception resources and have not significantly improved the perception results, and may even cause the perception results to deteriorate). Therefore, how to select appropriate perception nodes is an urgent problem to be solved. This solution can effectively reduce system overhead by first decomposing the perception task into subtasks with similar functions (i.e., the above-mentioned perception sub-requests), first obtaining the perception results of all perception nodes with a lower overhead, and then selecting the appropriate perception node to perform the perception task based on the execution status of the subtasks (i.e., the execution results corresponding to the above-mentioned perception sub-requests).

[0290] Embodiment 2: The SF requests multiple RAN / UE nodes to report surrounding signal conditions and selects a node based on signal strength. Optionally, after querying multiple RAN / UE nodes (corresponding to the at least one sensing node mentioned above), the SF obtains auxiliary information and reference signal reports (corresponding to the measurement information mentioned above) from each node to obtain the sensing channel and signal strength of each node, and then selects the corresponding node for the sensing task.

[0291] FIG10 is a flow chart of a communication method provided in yet another embodiment of the present application. As shown in FIG10 , the method includes:

[0292] S1001. Consumer NF sends a perception request to SF (corresponding to the first perception request mentioned above).

[0293] S1002. The SF determines the corresponding perception node (corresponding to the at least one perception node mentioned above, where a perception node includes a RAN device or a terminal device) according to the perception request sent by the Consumer NF.

[0294] S1003. SF sends a first request to the queried perception node (corresponding to the at least one perception node mentioned above).

[0295] Optionally, the first request may be used to request auxiliary information.

[0296] S1004. The sensing node reports auxiliary information to the SF.

[0297] Optionally, the auxiliary information may include at least one of the following: cell identification information and / or terminal device identification information corresponding to the reference signal received by the sensing node, and cell identification information and / or terminal device identification information corresponding to the reference signal received by other sensing nodes.

[0298] Optionally, the auxiliary information may also include identification information of the sensing node. For example, the identification information of a sensing node may include identification information and / or address information of a RAN node, or the identification information of a sensing node may include identification information and / or address information of a terminal device. Optionally, the address information may include Media Access Control (MAC) address information and / or Internet Protocol (IP) address information, etc.

[0299] S1005. SF sends a second request to the queried perception node (corresponding to the at least one perception node mentioned above).

[0300] Optionally, the second request may be used to request measurement information.

[0301] Optionally, the measurement information may be measurement information of surrounding reference signals. The measurement information may include at least one of the following: reference signal strength, reference signal quality, monitored channel information, SINR, distance information from the node sending the signal, and information on whether the transmission is LOS or NLOS.

[0302] S1006: The sensing node measures surrounding reference signals.

[0303] S1007. The sensing node reports measurement information to the SF.

[0304] Optionally, the measurement information carries ID information of the current node, and also carries information such as a Cell ID or UE ID corresponding to the measurement information.

[0305] Optionally, step S1003 may be combined with step S1005 and sent in the same message, and / or step S1004 may be combined with step S1007 and sent in the same message. Optionally, step S1003 and step S1004 may be skipped, that is, step S1003 and S1004 are not included, and the SF obtains the context information by querying the locally stored context information, or by querying other core network elements (such as AMF / UDR / UDM).

[0306] S1008. The SF selects a sensing node (corresponding to one or more sensing nodes in the above embodiment) corresponding to the measurement information based on the measurement information and auxiliary information reported by the sensing node.

[0307] Optionally, the SF may determine the perception node ID corresponding to the measurement information based on the measurement information and auxiliary information reported by the perception node, and then select the node corresponding to the measurement information for executing the perception service by screening the measurement information.

[0308] S1009. SF sends a sensing request (corresponding to the second sensing request mentioned above) to the sensing node corresponding to the selected measurement information to perform the sensing task.

[0309] This solution obtains auxiliary information from sensing nodes and reference signal information reported by sensing nodes (corresponding to the aforementioned measurement information). After obtaining the reference signal information, it selects an appropriate sensing node to perform the sensing task based on the reference signal information, effectively reducing system overhead. Compared to Example 1, this solution further reduces system overhead (no sensing task needs to be performed, only reference signal information and auxiliary information need to be collected). However, because reference signal strength information cannot directly reflect the execution of the sensing task, the node selected may not be optimal compared to Example 1.

[0310] Example 3: The SF prioritizes RAN / UE nodes with similar sensing tasks. Optionally, upon receiving sensing task A (corresponding to the first sensing request described above), the SF first selects a sensing node and then stores the corresponding context information. Upon receiving sensing task B (corresponding to the fourth sensing request described above), the SF prioritizes node selection based on the stored context information of sensing task A and then updates the sensing task.

[0311] FIG11 is a flow chart of another communication method provided in another embodiment of the present application. As shown in FIG11 , the method includes:

[0312] S1101. Consumer NF sends a perception request A (corresponding to the first perception request mentioned above) to SF.

[0313] S1102. The SF determines the corresponding perception node (corresponding to the at least one perception node mentioned above, where a perception node includes a RAN device or a terminal device) according to the perception request A sent by the Consumer NF.

[0314] S1103. SF selects a perception node (corresponding to one or more perception nodes mentioned above).

[0315] Optionally, the SF may select a sensing node through the first embodiment or the second embodiment or other methods.

[0316] S1104. SF sends perception request 1 (corresponding to the second perception request mentioned above) to the selected perception node.

[0317] Optionally, Sensing Request 1 corresponds to Sensing Request A and may include the same sensing task. Optionally, there may be multiple Sensing Requests 1 sent to different sensing nodes. Optionally, Sensing Requests 1 sent to different sensing nodes all correspond to Task A, but the specific parameters may differ. For example, if the requested areas are different, Sensing Request 1 may be Cell ID 1, Sensing Request 2 may be Cell ID 2, and so on.

[0318] S1105. Consumer NF sends a perception request B (corresponding to the fourth perception request mentioned above) to SF.

Optionally, the area awareness request B and the area awareness request A have a partial or complete overlapping area, and the awareness mode and awareness service type are the same or similar.

[0321] S1106. SF discovers the corresponding perception node (corresponding to one or more nodes mentioned above) based on the area information in the perception request B.

[0323] Optionally, the SF may preferentially select a node that performs similar sensing tasks in the same area and use it as the first sensing node.

[0324] S1108. SF sends the updated perception request (corresponding to the fifth perception request mentioned above) to the node (i.e., the first perception node) that is also serving perception request A.

[0325] Optionally, the updated sensing request can simultaneously complete the tasks of sensing requests A and B. For example, if sensing request A requires a sensing accuracy of 0.2m and a reporting frequency of 1 time / s, and sensing request B requires a sensing accuracy of 0.1m and 2 times / s, the sent sensing request will have an accuracy of 0.1m and a reporting frequency of 1 time / s. The request may also include requirements in other dimensions, such as credibility probability (corresponding to the accuracy information mentioned above) and false alarm rate. SF can select the most stringent requirement for configuration update.

[0326] In an embodiment of the present application, further perception resource savings are achieved by querying the existing perception task context and reusing the perception node to perform the perception task.

[0327] The present application provides an embodiment in which, after receiving a sensing request, the SF generates a sensing subtask based on the sensing request and sends it to the discovered RAN / UE node. The SF selects the final UE / RAN to perform the sensing task based on the execution of the sensing subtask.

[0328] This application provides an embodiment in which a Service Provider (SF) selects a RAN / UE node for sensing based on reference signal measurement information and assistance information reported by the RAN / UE node. The SF requests reference signal measurement information from the discovered RAN / UE. The SF also queries assistance information for the discovered RAN / UE and its surrounding nodes.

[0329] The present application provides an embodiment, in which after receiving a perception request, SF queries the current perception task context, preferentially selects a node that can be reused, and updates the perception request to the node, so that the node can complete multiple perception tasks at the same time.
