Abstract
Description
A sensing communication method, device and system
[0001] The present application claims priority to the Chinese Patent Application No. 202410727038.2, filed on June 5, 2024, and entitled “A sensing communication method, device and system”, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD
[0002] The present application relates to the technical field of wireless communication, in particular to a sensing communication method, device and system. BACKGROUND
[0003] 5.5G (full name “5G-A mobile communication technology”, which is an enhanced version of 5G). First, it is to continue to enhance the three standard scenarios of eMBB, mMTC and URLLC defined by ITU. Then 5.5G also expands three new scenarios, including uplink ultra-wideband UCBC (Uplink Centric Broadband Communication), wideband real-time interaction (Real-time Broadband Communication, RTBC) and communication and sensing fusion (Harmonized Communication and Sensing, HCS, also known as Integrated sensing and communication, ISAC), as shown in FIG. 1, which changes the “triangle” of the 5G scenario to a more rich “hexagon”. HCS fusion sensing communication is usually used to help the development of automatic driving. HCS mainly enables two scenarios of vehicle networking and unmanned aerial vehicles, and supports automatic driving as a key requirement. By applying the beam scanning technology of Massive MIMO of cellular network to the field of sensing, it can provide both communication and sensing in the HCS scenario; if extended to indoor scenarios, it can also provide positioning services. The currently identified sensing modes can be divided into terminal-related sensing modes (i.e., terminal-involved sensing modes) and base station-related sensing modes (i.e., base station-involved sensing modes).
[0004] For terminal-related sensing modes, the terminal is relatively sensitive to participating in sensing tasks, although the network side can currently indicate the terminal to participate in sensing tasks through direct indication. However, the terminal participating in the sensing task will occupy the resources and energy of the terminal, and involves the privacy of the terminal, and if the terminal is directly instructed to participate in the sensing task, it may cause the terminal-related sensing mode to not work normally or face the risk of infringement of the terminal. SUMMARY
[0005] The application provides a sensing communication method, device and system, which ensures that a terminal participates in a sensing task without infringement and makes a sensing mode related to the terminal work normally.
[0006] In a first aspect, the embodiments of the application provide a sensing communication method, which comprises: a first network element determining first information of a first terminal, the first information indicating whether the first terminal is allowed to participate in a sensing task or not. When the first information indicates that the first terminal is allowed to participate in the sensing task, the first network element performs a sensing task through the first terminal.
[0007] That is, when the first information indicates that the first terminal is allowed to participate in the sensing task, the first network element performs sensing measurement through the first terminal.
[0008] As an example, when the first information indicates that the first terminal is not allowed to participate in the sensing task, the first network element does not perform the sensing task through the first terminal.
[0009] In the method provided by the embodiments of the application, the first network element determines the first information indicating whether the first terminal is allowed to participate in the sensing task before performing the sensing task through the first terminal, and then determines, according to the first information, that if the first terminal is allowed to participate in the sensing task, the sensing task is performed through the first terminal to perform a subsequent sensing-related process. In this way, the infringement of the rights and interests of the terminal caused by directly participating in the sensing task without the authorization of the first terminal can be avoided, the performance of the sensing task through the first terminal meets the will of the first terminal, and the sensing work can be ensured to be performed normally.
[0010] In a possible implementation manner of the application, before the first network element determines the first information, the method provided by the embodiments of the application further comprises:
[0011] The first network element determines the first terminal participating in the sensing task. In this scheme, the first network element can first determine the first terminal participating in the sensing task, and then confirm whether the first terminal participates in the sensing task based on the first information of the first terminal. It can be understood that in this case, even if the first terminal is the terminal participating in the sensing task determined by the first network element, if the first network element determines that the first terminal is not allowed to participate in the sensing task, the first network element will not perform sensing measurement through the first terminal subsequently.
[0012] In a possible implementation manner of the application, the first network element has the first information of the first terminal. Since the first network element has the first information, it can be avoided that the first network element acquires the first information from other network elements storing the sensing authorization information of the first terminal after or before determining the first terminal participating in the sensing task.
[0013] In a possible implementation of the present application, the first network element determines the first information of the first terminal, including: the first network element sends a first request message, the first request message being used to request the first information of the first terminal. The first network element receives the first information from a second network element. For example, the first network element can send a first request message to the second network element, and the second network element can be a network element storing the awareness authorization information of the first terminal. For example, the second network element can be a UDM or an SF or an AF or a SaF or a radio access network device.
[0014] In a possible implementation of the present application, the first information is the awareness authorization information of the first terminal. The awareness authorization information of the first terminal is used to indicate whether the first terminal is allowed to participate in an awareness task. For example, the awareness authorization information of the first terminal includes one or more indication information used to indicate whether the first terminal is allowed to participate in an awareness task.
[0015] In a possible implementation of the present application, the first information includes any one or more of the following: first indication information used to indicate whether the first terminal is allowed to participate in an awareness task; second indication information used to indicate whether the first terminal is allowed to participate in an awareness task in a specific awareness mode; third indication information used to indicate whether a communication signal of the first terminal is allowed to be acquired by an awareness task; fourth indication information used to indicate whether location information of the first terminal is allowed to be acquired by an awareness service; and fifth indication information used to indicate whether the first terminal authorizes a timer of an awareness task or subscribes to a result of an awareness task in which the first terminal participates.
[0016] In a possible implementation of the present application, the communication signal of the first terminal includes any one or more of the following: an SRS of the first terminal; an uplink data transmission signal of the first terminal; and a measurement signal of the first terminal.
[0017] In a possible implementation of the present application, the second information is obtained, the second information being used to indicate information of one or more public land mobile networks (PLMNs) to which the first information is applicable; and the first network element performs an awareness task by using the first terminal according to that the first information indicates that the first terminal is allowed to participate in the awareness task, including: the first network element performs the awareness task by using the first terminal in any PLMN network to which the first information is applicable. By determining the information of one or more public land mobile networks to which the first information is applicable, it can be avoided that the first terminal participates in an awareness task in a PLMN network to which the first information is not applicable.
[0018] For example, the second information can be information of one or more PLMN networks corresponding to the first information, and the information of the one or more PLMNs is used to determine the PLMN network to which the first information is applicable. For example, the one or more PLMN networks corresponding to the first information can be information of the PLMN network to which the first information is applicable, or can be information of the PLMN network to which the first information is not applicable. If the one or more PLMN networks corresponding to the first information is information of the PLMN network to which the first information is not applicable, the first network element can determine that the first information of the first terminal is applicable to other PLMNs except the one or more PLMNs to which the first information is not applicable.
[0019] For example, the second information can be identification information of the first terminal, or the second information can be information indicating that the first information of the first terminal is applicable to any PLMN network. For example, if the second information indicates that the first information does not correspond to information of any PLMN network, it can be considered that the first information is applicable to any network.
[0020] In a possible implementation of the present application, the first network element is a first module corresponding to a radio access network device, and the first module is configured to perform sensing-related functions. The method provided by the embodiments of the present application further includes: the first network element sends a second request message to a CU of the radio access network device or to a sensing network element through a first communication interface, the second request message being used to request location information of the first terminal, and the first communication interface being a communication interface between the sensing network element and the first network element; and the first network element receives the location information of the first terminal from the CU of the radio access network device or from the first communication interface. The first network element determines whether to select the first terminal to participate in a sensing task and / or in which sensing measurement mode the first terminal participates in the sensing task according to the information of the first terminal.
[0021] In a possible implementation of the present application, the second request message further includes: accuracy requirements of the location information, and / or location information reporting trigger conditions / periods.
[0022] In a possible implementation of the present application, the location information of the first terminal further includes attributes of the location information and / or time effectiveness corresponding to the location information.

[0025] For example, the terminal can send the sensing authorization information of the terminal to a radio access network device accessed by the terminal, or send the sensing authorization information of the terminal to an SF, or send the sensing authorization information of the terminal to an AMF, or send the sensing authorization information of the terminal to a SaF. In this solution, the terminal reports the sensing authorization information of the terminal, so that in subsequent sensing measurement processes, the first network element can perform sensing measurement through the first terminal without infringing the rights and interests of the terminal.
[0026] For example, the terminal can actively or based on triggering of other network elements send the sensing authorization information of the terminal. For example, the terminal can send the sensing authorization information of the terminal in a handover process or a context migration process. For example, the sensing authorization information of the terminal should be included in the UE context. For example, the sensing authorization information of the terminal is included in a HANDOVER REQUEST message.
[0027] In a possible implementation manner of the present application, the method provided by the embodiments of the present application can further include that the terminal sends the location information of the terminal.

The storage unit can be a storage unit (e.g., a register, a cache, etc.) in the chip, or a storage unit (e.g., a read-only memory, a random access memory, etc.) outside the chip in the first network element.
[0032] For example, the communication device comprises a processing unit configured to determine first information of the first terminal, the first information indicating whether the first terminal is allowed to participate in the sensing task or not. When the first information indicates that the first terminal is allowed to participate in the sensing task, the processing unit is configured to perform the sensing task by the first terminal. That is, when the first information indicates that the first terminal is allowed to participate in the sensing task, the processing unit is configured to perform the sensing measurement by the first terminal.
[0033] For example, the first information indicates that the first terminal is not allowed to participate in the sensing task, and the processing unit is configured not to perform the sensing task by the first terminal.

[0092] 6) Sensing device: Device sending sensing signal and / or receiving sensing signal and performing corresponding signal processing, including base station and terminal. Sensing node can act as sensing device.
[0093] 7) Sensing raw data: Received signal or original channel information (such as complex results of received signal or channel response, amplitude and / or phase, I / Q and related operation results thereof).
[0094] 8) Sensing measurement data: Measurement data obtained by sensing device based on processing of received signal or original channel information, as shown in Table 3.

[0099] Mode 1, base station self-generation and self-reception:
[0100] In this scenario, as shown in (a) of FIG. 1, taking gNB as an example, the gNB is a key unit in the 5G (NR) wireless communication system, as a base station in the 5G radio access network (RAN). The gNB1 communicates with the SF. The gNB1 can send configuration information of resources on which the gNB1 sends the sensing signal to the sensing network element. The sensing network element can send signaling to the gNB1 to instruct the gNB1 to perform sensing measurement. The gNB1 is configured to send the sensing signal on the resources of the sensing signal. The sensing signal is reflected / scattered / diffracted by the sensing target (such as a vehicle) in the environment during propagation, and then received by the gNB1. Then the gNB1 measures the received reflected signal / scattered signal / diffracted signal, obtains the sensing measurement result, and reports it to the SF.
[0101] Mode 2, base station 1 sends and base station 2 receives:
[0102] In this scenario, as shown in (b) of FIG. 1, taking gNB as an example, the gNB1 and the gNB2 respectively communicate with the SF. The gNB1 is configured to send the sensing signal on the resources of the sensing signal, and the sensing signal is reflected / diffracted / scattered by the sensing target (such as vehicle A) in the environment during propagation, and then received by the gNB2. Then the gNB2 measures the received reflected signal / diffracted signal / scattered signal, obtains the sensing measurement result. The gNB2 reports the sensing measurement result to the SF.
[0103] It can be understood that in the architecture shown in (b) of FIG. 1, the gNB1 can also be used as a sending end to send the sensing signal. The gNB2 can also be used as a receiving end to receive the signal reflected / diffracted / scattered by the sensing target (such as vehicle A) after the sensing signal, and perform sensing measurement.
[0104] Mode 3, base station sends and terminal receives:
[0105] In this scenario, as shown in (c) of FIG. 1, taking gNB as an example, the gNB1 communicates with the sensing network element. For example, the sensing network element can send sensing signaling to the terminal to instruct the terminal to perform sensing measurement.
[0106] The gNB1 sends the sensing signal, and the sensing signal is reflected / scattered / diffracted by the sensing target in the environment during propagation, and then received by the terminal. Then the terminal measures the received signal, obtains the sensing measurement result, and reports it to the SF.
[0107] Mode 4, terminal sends and base station receives:
[0108] In this scenario, as shown in (d) of FIG. 1, taking a gNB as an example, gNB1 communicates with the sensing network element. For example, the sensing network element instructs gNB1 to configure sensing resources for the terminal to send sensing signals. gNB1 can report the configuration information of the resources for the terminal to send sensing signals to the sensing network element. The sensing network element can send sensing signaling to gNB1 to instruct gNB1 to perform sensing measurement.
[0109] The terminal sends sensing signals on the configured resources for sending sensing signals. The sensing signals are reflected / scattered / diffracted by the sensing target in the environment during propagation and then received by gNB1. Then gNB1 measures the received signals to obtain sensing measurement results. gNB1 reports the sensing measurement results to the SF.
[0110] Mode 5, terminal spontaneous self-reception:
[0111] In this scenario, as shown in (e) of FIG. 1, the terminal sends sensing signals on the resources configured by the gNB for the terminal. The sensing signals are reflected / scattered / diffracted by the sensing target in the environment during propagation and then received by the terminal. Then the terminal measures the received signals to obtain sensing measurement results. The terminal reports the sensing measurement results to the SF.
[0112] Mode 6, terminal A sends and terminal B receives:
[0113] In this scenario, as shown in (f) of FIG. 1, terminal A sends sensing signals on the resources configured by the gNB for terminal A. The sensing signals are reflected by the target in the environment during propagation and then received by terminal B. Then terminal B measures the received signals to obtain sensing measurement results. Terminal B reports the sensing measurement results to the SF.
[0114] It is worth noting that the architecture flow shown in FIG. 1 is only illustrative and does not limit the scenarios of the sensing mode. In actual processes, the sensing mode can also correspond to other architectures and corresponding flows.
[0115] Based on the above sensing modes, the sensing signaling interaction in the sensing process is introduced as follows:
[0116] The sensing signaling interaction can be divided into the following four modes according to different network elements participating in sensing: SF and gNB signaling interaction, SF and terminal signaling interaction, gNB and terminal signaling interaction, and terminal and terminal signaling interaction. The demand relationship between different sensing modes and the interaction between three network elements (SF, gNB, and terminal) is shown in Table 1:
[0117] Table 1 Demand relationship between different sensing modes and network element interaction
[0118] Among them, the base station self-initiated self-reception mode and the base station 1 initiated base station 2 reception mode are both through the network side, as shown in Table 1, usually involves the interaction between SF and base station, specifically, the interaction content between SF and base station can refer to the description in Table 2, which will not be repeated here.
[0119] The base station initiated terminal reception mode and the terminal initiated base station reception mode require the network side and the terminal side to cooperate with the sensing, which requires the interaction between SF and base station, SF and terminal, and base station and terminal. Specifically, the interaction content between SF and base station, SF and terminal, and base station and terminal can refer to the description in Table 2, which will not be repeated here.
[0120] For the terminal self-initiated self-reception mode and the terminal A initiated terminal B reception mode, although the sensing process does not require the participation of the base station, considering that all sensing resources belong to air interface resources, which should be managed and allocated by the base station, and the terminal needs to report the sensing capability of the terminal (i.e. whether it supports sensing) to the base station / SF, therefore, the four interaction modes exist in the two sensing modes. It should be noted that in the sensing mode involving the terminal, it is assumed that the interaction between SF and terminal is through non-access layer signaling, and the process of interaction is transparent to the base station, thereby avoiding the complexity brought by the interaction of three nodes of SF, base station and terminal.
[0121] For the six sensing modes, although the network element interaction involved may be different, the sensing process is basically the same, which is generally divided into three steps: sensing capability reporting, sensing measurement configuration, and sensing measurement reporting. Sensing capability reporting is usually the first step in the sensing process, which reports the sensing mode supported by the terminal / base station and the capability related to sensing signal processing, so as to help the sensing network element / base station (in the terminal A initiated terminal B reception mode without network participation, the sensing management terminal) to determine the use of appropriate sensing mode and sensing resource. Sensing measurement configuration is the second step in the sensing process, which aims to determine the allocation of sensing resources according to the sensing demand after the terminal / base station receives the sensing demand from the SF, so this process is reflected in the above four interaction modes. In the sensing measurement configuration process related to air interface resources, the base station as a network element that must be involved is responsible for the allocation of air interface resources, so this process exists in the interaction process between SF and base station and between base station and terminal. The sensing configuration related to non-air interface resources may be directly interacted by SF and terminal. Sensing measurement reporting is the last step in the sensing process, which aims to report the collected sensing measurement data to SF or the sensing management terminal, and the network element reported in different sensing modes can be terminal / base station. Therefore, the basic sensing process corresponds to the different network element interaction processes in different sensing modes, as shown in Table 2.
[0122] Table 2 Relationship between different sensing modes, basic processes and network element interaction requirements
[0123] As shown in Table 3, in different perception scenarios and service requirements, the perception signal received by the perception device may need to be processed by one or more processing nodes, such as a terminal, a radio access network device, or a NWDAF (Network Data Analytics Function), or a SF, or a perception server, and the like, to obtain the final perception measurement data or the perception result.
[0124] Table 3
[0125] As known from the above, the terminal may need to participate in the perception measurement when performing the perception measurement. For the terminal-related perception mode, i.e., the scenario in which the terminal participates in the perception task, the terminal participating in the perception task is relatively sensitive. Since the terminal participating in the perception task occupies the resources and energy of the terminal, whether the terminal is willing to participate in the perception task may need to be negotiated. If there is no subscription of the terminal and the perception measurement is directly performed through the terminal, the risk of infringement on the terminal will be faced, and the terminal-related perception mode may not work normally.
[0126] Based on this, an embodiment of the present application provides a perception measurement method. The method first determines whether the terminal is allowed / authorized to participate in the perception task before the terminal participates in the perception task. In the case that the terminal is allowed / authorized to participate in the perception task, the terminal participates in the perception task. The scheme can ensure that the terminal-related perception mode works normally while avoiding the risk of infringement on the terminal device.
[0127] The technical solutions of the present application can be applied to various communication systems, for example: long time evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD) system, universal mobile telecommunication system (UMTS), worldwide interoperability for microwave access (WiMAX) communication system, public land mobile network (PLMN) system, device to device (D2D) network system or machine to machine (M2M) network system, and the 5th generation (5G) system, etc.
[0128] The network architecture and service scenarios described in the embodiments of the present application are used to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. It can be known by those skilled in the art that, with the evolution of network architecture and the appearance of new service scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.
[0129] As shown in FIG. 3, FIG. 3 is a communication system provided by the embodiments of the present application, which includes a radio access network (RAN) 100 and a core network (CN) 200. The RAN 100 includes at least one RAN device (such as RAN devices 110a and 110b in FIG. 3, collectively referred to as RAN devices 110) and at least one terminal (such as terminals 120a-120j in FIG. 3, collectively referred to as terminals 120). Other RAN nodes can also be included in the RAN device. For example, wireless relay devices and / or wireless backhaul devices (not shown in FIG. 3). The terminal 120 is connected to the RAN device 110 in a wireless manner. The RAN device 110 is connected to the core network 200 in a wireless or wired manner. The core network device in the core network 200 and the RAN device 110 in the radio access network 100 can be different physical devices respectively, or can be the same physical device integrated with the logical functions of the core network and the logical functions of the radio access network.
[0130] As shown in FIG. 3. The core network has a sensing network element-sensing function (SF) 201 and a sensing authentication network element 202.
[0131] In the architecture shown in FIG. 1 and FIG. 3, the sensing network element 201 is a device or component deployed in the core network or the radio access network to provide sensing function for the network. It can also be called SMF (Sensing management function) or other names, which are not limited in the embodiments of the present application.
[0132] The terminal 120 in the embodiments of the present application can be in a stationary state or a mobile state, and the terminal 120 can be a sensing-capable terminal. The terminal 120 can report sensing authorization information of the terminal 120. The sensing authorization information is used to indicate whether the terminal 120 is allowed / authorized to participate in a sensing task. For example, the terminal 120 can report the sensing authorization information of the terminal 120 to a network element (such as an SMF, an SF, a sensing authentication network element 202, or an AF) in the core network. Alternatively, the terminal 120 can also report the sensing authorization information of the terminal 120 to a network element in the RAN 100.
[0133] As an example, the terminal 120 reports the sensing authorization information of the terminal 120 to the sensing authentication network element 202. The sensing authentication network element 202 is used to obtain the sensing authorization information of the terminal 120, and to send the sensing authorization information of the terminal 120 to the RAN device 110 or the SF 201 or the UDM. The sensing authorization information of the terminal 120 is used to determine whether the terminal 120 is allowed to participate in a sensing task.
[0134] Optionally, the sensing authorization information of the terminal 120 is also used to indicate that the terminal 120 is allowed to participate in a sensing task in a specific sensing mode or to indicate that the terminal 120 is not allowed to participate in a sensing task in which sensing mode. For example, the sensing authorization information of the terminal 120 is also used to indicate that the terminal 120 is allowed to participate in a sensing task in a terminal-to-base station reception sensing mode and is allowed to participate in a sensing task in a terminal-to-terminal sensing mode. In this case, it can be implicitly determined that the sensing authorization information of the terminal 120 is not allowed to participate in a sensing task in a base station-to-terminal reception sensing mode. Alternatively, the sensing authorization information can also explicitly indicate that the terminal 120 is not allowed to participate in a sensing task in a base station-to-terminal reception sensing mode.
[0135] It can be understood that in the terminal self-initiated self-received sensing mode, the terminal 120 determines the resource for sending the sensing signal. The SF 201 sends a sensing measurement instruction to the terminal 120, for instructing the terminal 120 to perform the sensing measurement. Optionally, the sensing measurement instruction further includes information of the sensing target, for the terminal 120 to determine the position of the sensing target. Optionally, the sensing measurement instruction is further used to instruct the terminal 120 to perform the sensing measurement in the terminal self-initiated self-received sensing mode. The terminal 120 is used to send the sensing signal on the resource configured by the RAN device 110 for the terminal 120, and receive the transmission signal after the sensing signal passes through the sensing target, and perform the sensing measurement on the received transmission signal, obtain the sensing measurement result, and report to the SF.
[0136] It can be understood that in the terminal self-initiated self-received sensing mode, the terminal 120 determines the resource for sending the sensing signal. The terminal 120 can obtain the resource configured by the RAN device 110 for the terminal 120 from the RAN device 110. The SF 201 is used to send a sensing measurement instruction to the RAN device 110, for instructing the RAN device 110 to perform the sensing measurement.
[0137] Optionally, the sensing measurement instruction further includes information of the sensing target, for the RAN device 110 to determine the position of the sensing target. The terminal 120 is used to send the sensing signal on the resource. The RAN device 110 is used to receive the transmission signal after the sensing signal passes through the sensing target, and perform the sensing measurement on the received transmission signal, obtain the sensing measurement result, and report to the SF.
[0138] It can be understood that in the terminal self-initiated self-received sensing mode, the terminal 120 determines the resource for sending the sensing signal. The terminal 120 can obtain the resource configured by the RAN device 110 for the terminal 120 from the RAN device 110. The SF 201 is used to send a sensing measurement instruction to the RAN device 110, for instructing the RAN device 110 to perform the sensing measurement.
[0139] The RAN 100 can be a 3rd generation partnership project (3GPP)-related cellular system, such as a 4G, 5G mobile communication system, an NTN (non-terrestrial network) system, or a future-oriented evolution system (e.g., a 6G mobile communication system). The RAN 100 can also be an open RAN (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (WiFi) system, and can also be a communication system in which two or more of the above systems are fused.
[0140] In the present application, the RAN 100 can be an NTN (non-terrestrial network) system, and the RAN 100 can be in a transparent mode or a regenerative mode, an earth fixed cell or an earth moving cell.
[0141] The terminal can have a sensing capability, for example, the terminal 120 includes various handheld devices, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem with wireless communication functions. The terminal can refer to a user equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user device. The terminal can also be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a machine type communication (MTC) terminal, a tag, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication functions, a computing device, or other processing devices connected to a wireless modem, a vehicle-mounted device, a handheld device, a wearable device, a computing device, a portable device, or a vehicle-mounted device, a terminal in the form of a smart phone, smart glasses, a terminal device in a 5G network, or a terminal in a future evolution of a public land mobile network (PLMN), etc. The embodiments of the present application are not limited thereto.
[0142] In addition, the terminal can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; the terminal can also be deployed on water (such as ships, etc.); the terminal can also be deployed in the air (such as airplanes, balloons, and satellites, etc.). The terminal can be a mobile phone, a pad, a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The terminal device can also be a communication chip with a communication module, or a vehicle with a communication function, or a vehicle-mounted device (such as a vehicle-mounted communication device, a vehicle-mounted communication chip), etc.
[0143] The RAN device 110, which can also be referred to as an access network device, a RAN entity, or an access node, etc., forms part of the communication system, and helps the terminal 120 to access the wireless access. The RAN devices 110 in the communication system 1000 can be of the same type or of different types. In some scenarios, the roles of the RAN device 110 and the terminal 120 are relative, for example, the terminal 120i in FIG. 3 can be a helicopter or a drone, which can be configured as a mobile base station, and for those terminals 120j accessing the RAN 100 through the terminal 120i, the terminal 120i is a base station; but for the RAN device 110a, the terminal 120i is a terminal. The RAN device 110 and the terminal 120 are sometimes collectively referred to as communication devices, for example, the RAN device 110a and the RAN device 110b in FIG. 3 can be understood as communication devices with base station functions, and the terminal 120a- the terminal 120j can be understood as communication devices with terminal functions.
[0144] Wireless access network device: an apparatus deployed in a wireless access network to provide wireless communication functions for terminals meeting 4G standards, such as evolved node B (eNB) in long term evolution (LTE) system. The eNB can include various forms of macro base station, micro base station (also known as small station), relay station, access point, wearable device, vehicle-mounted device. The eNB can also be a transmission and reception point (TRP).
[0145] Wireless access network device: an apparatus deployed in a wireless access network to provide wireless communication functions for terminals meeting 5G standards, such as next generation base station (g nodeB, gNB). The gNB can include various forms of macro base station, micro base station (also known as small station), relay station, access point, wearable device, vehicle-mounted device. The gNB can also be a transmission and reception point (TRP), transmission measurement function (TMF). The gNB can include a central unit (CU) and a distributed unit (DU) integrated on the gNB.
[0146] In addition to the foregoing, the radio access network device can also be a radio network controller (RNC), a radio controller under a cloud radio access network (CRAN) system, a base station controller (BSC), a home base station (for example, a home evolved nodeB, or home node B, HNB), a baseband unit (BBU), a transmitting and receiving point (TRP), a transmitting point (TP), a mobile switching center, a base transceiver station (BTS) in a global system for mobile communication (GSM) or code division multiple access (CDMA) network, a node base station (NB) in wideband code division multiple access (WCDMA), an evolved NB (eNB or eNodeB) in LTE, a base station device in a future 5G network or an access network device in a future evolved PLMN network, a wearable device, or a vehicle-mounted device.
[0147] As shown in FIG. 4A, taking the communication system shown in FIG. 3 as an example, in the 5G network architecture, in addition to the above-mentioned sensing network element, terminal, and wireless access network device, the 5G network architecture can further include an access and mobility management function (AMF) network element, an application function (AF) network element, a network exposure function (NEF) network element, a network data analysis function (NWDAF) network element, a unified data management (UDM) network element, a policy control function (PCF) network element, a data network (DN), and a location management function (LMF) network element.
[0148] The AMF is mainly responsible for mobility management in the mobile network, such as user location update, user registration network, and user handover.
[0149] The SMF is mainly responsible for session management in the mobile network, such as session establishment, modification, and release. Specific functions include allocating IP addresses for users, selecting UPFs that provide message forwarding functions, and the like.
[0150] The PCF is responsible for providing policies to the AMF and the SMF, such as QoS policies and slice selection policies.
[0151] The UDM is used to store user data, such as subscription information and authentication / authorization information.
[0152] The AF (Application Function) is responsible for providing services to the 3GPP network, such as affecting service routing and interacting with the PCF for policy control.
[0153] The NEF (Network Exposure Function) exposes the capabilities of each NF and is responsible for converting internal and external information.
[0154] The UPF is mainly responsible for processing user messages, such as forwarding, charging, and the like.
[0155] In the architecture, the SF can reuse the interfaces between the LMF and the 5GC (5G Core Network) network elements such as the AMF (Access and Mobility Management Function), the NEF (Network Exposure Function), the UDM (Unified Data Management), the NWDAF (Network Data Analytics Function), and the PCF (Policy Control Function) for sensing interaction. The sensing control signaling between the LMF (including the SF) and the RAN (Radio Access Network) or the UE is transmitted through the AMF. The sensing measurement data obtained by the RAN / UE can be transmitted to the LMF (including the SF) via the control plane, using the LPP (LTE Positioning Protocol) or NRPPa (NR Positioning Protocol Annex) protocol, or can be transmitted through the user plane, using the UPF (User Plane Function) to forward or directly transmit to the LMF (including the SF).
[0156] The newly added SF network element in the architecture can be independently deployed or co-deployed with the 5GC network elements (such as the AMF or the LMF) according to the sensing requirements. The network element can implement basic sensing functions such as sensing authorization, sensing control, sensing measurement data processing, and result output. If the sensing function is co-deployed with the LMF, the LMF and the GMLC (Gateway Mobile Location Center) need to be enhanced in function to support basic sensing functions. The GMLC is the first network element in the operator network that processes sensing requests, performs privacy checks or authorization functions, routes sensing requests to the AMF, performs LMF selection, etc. The SF can also be deployed on the RAN side as an independent network device or belong to the access network device and interact with other network elements.
[0157] The sensing network element sets up interfaces with the 5GC network elements such as the AMF, the NEF, the UDM, the NWDAF, the PCF, the LMF, and the UPF and interacts with them. The specific interface definitions are as follows:
[0158] NS1 interface: newly added interface between the sensing network element and the AMF. The NS1 interface can transmit sensing control signaling. For the scenario of transmitting sensing measurement data on the control plane, the interface can also transmit sensing measurement data.
[0159] NS2 interface: a newly added interface between the sensing network element and the NEF, the NS2 interface can transmit signaling messages exchanged between the sensing network element and the application function (AF) through the NEF, and the sensing result is also opened to the AF;
[0160] NS3 interface: a newly added interface between the sensing network element and the UDM, through the NS3 interface, authentication or authorization can be realized, and the sensing subscription information, service AMF information or other information of the terminal can be obtained;
[0161] NS4 interface: a newly added interface between the sensing network element and the NWDAF, through the NS4 interface, the sensing network element can complete the artificial intelligence (AI) processing related to the sensing service together with the NWDAF;
[0162] NS5 interface: a newly added interface between the sensing network element and the PCF, through the NS5 interface, the sensing network element can transmit the sensing requirements, QoS requirements or sensing results of the sensing service to the PCF, and the PCF can generate the PCC strategy related to the sensing service;
[0163] NS6 interface: a newly added NS6 interface between the sensing network element and the LMF, through the NS6 interface, the sensing network element can obtain the location related information, such as the sensing area, the RAN information of the sensing target, and the location information of the sensed UE;
[0164] NS7 interface: a newly added interface between the sensing network element and the user plane function, the sensing measurement data can be directly transmitted from the (R)AN to the sensing network element through the user plane function, or indirectly forwarded to the sensing network element through the UPF, and if the UPF is used for forwarding in the scenario where the (R)AN performs sensing, the UPF needs to be modified to support the (R)AN granularity data transmission.
[0165] In addition to the above-mentioned newly added interfaces, the existing interfaces (such as N1, N2, N5, N8, N33, etc.) need to support the transmission of sensing service related information, such as authentication information, sensing service type, sensing service quality requirement, sensing measurement data, and sensing result.
[0166] If the sensing function is combined with the LMF, an interface needs to be added between the LMF and the GMLC to transmit the sensing service related information, and the interfaces related to the LMF and the GMLC (such as the NL1 interface between the AMF and the LMF, the NL2 interface between the AMF and the GMLC, the NL5 interface between the NEF and the GMLC, and the NL6 interface between the UDM and the GMLC) also need to support the sensing transmission of the sensing service related information, and the NL9 interface is added between the LMF and the GMLC. The specific description is as follows:
[0167] N33 interface: interface between AF and NEF, through which sensing service type, service requirement, sensing result, etc. can be transmitted;
[0168] NL5 interface: interface between NEF and GMLC, through which sensing service type, service requirement, sensing result, etc. can be transmitted;
[0169] NL6 interface: interface between GMLC and UDM, through which privacy check data can be transmitted;
[0170] NL2 interface: interface between NEF and AMF, through which sensing service type, service requirement, sensing result, etc. can be transmitted;
[0171] NL1 interface: interface between AMF and LMF, through which sensing service type, service requirement, sensing result, etc. can be transmitted;
[0172] New interface NL9: interface between GMLC and LMF, through which sensing service type, service requirement, sensing result, etc. can be transmitted.
[0173] As shown in FIG. 4B, FIG. 4B is another network deployment architecture, in which the sensing network element is independent of the 5G core network (5G Core, 5GC).
[0174] In the architecture shown in FIG. 4B, the sensing network element (Sensing Function, SF) does not need to interact with the 5GC or only performs less interaction. For scenarios where there is only a sensing demand in a specific area or only a sensing demand, this architecture can provide sensing services without the control of the 5GC or only with the participation of part of the network elements, and can also achieve that the sensing measurement data or sensing result does not go out of the park through the localization deployment of the sensing network element, thereby meeting the demand of enterprises for the security and privacy of sensing measurement data or sensing result, and reducing the sensing time delay. This architecture is simple, flexible and efficient, has fewer transmission nodes, is easy to deploy, and can optionally support terminal-related sensing requirements, and consider the implementation scheme of authorization, mobility management and billing functions as needed.
[0175] In this architecture, the sensing network element directly establishes a connection with the RAN node, and the sensing control plane signaling message and the sensing measurement data are transmitted through the interface NS1. When the terminal participates in sensing, the control plane signaling message is forwarded to the SF through the AMF, and the sensing measurement data is transmitted through NS1. In addition, the SF can also have an interface with the 5GC network element AMF, NEF or NWDAF to control the AF to provide the sensing service requirement to the SF through the core network function.
[0176] For example, the NS1 interface: the interface between the sensing network element and the (R)AN, which is used to transmit sensing control signaling or sensing measurement data; in one deployment implementation, the sensing function can also be deployed in the base station.
[0177] The NS2 interface: the interface between the sensing network element and the AMF, which is used to receive the sensing service requirement from the terminal or transmit the signaling message between the sensing network element and other network elements in the core network, such as the interaction message with the UDM.
[0178] The NS3 interface: the interface between the sensing network element and the NEF, which is used to transmit the signaling message of the interaction between the sensing network element and the service side AF through the NEF, and open the sensing result to the AF. The interaction between the sensing function and the AF can also not pass through the NEF.
[0179] In actual deployment, the NS2 interface and the NS3 interface can be deployed in one, that is, the AF sends the sensing service request to the SF indirectly through the NS2 (NEF) interface or directly to the SF (without NEF); or the AF sends the sensing service request to the SF through the NS3 interface (NEF) and the NS2 interface (AMF).
[0180] The NS4 interface: the interface between the sensing network element and the NWDAF, which is used to perform intelligent analysis and prediction with the NWDAF to generate the sensing result.
[0181] The communication between the access network device and the terminal follows a certain protocol layer structure. The protocol layer can include a control plane protocol layer and a user plane protocol layer. The control plane protocol layer can include at least one of the following: a radio resource control (RRC) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, a media access control (MAC) layer, or a physical (PHY) layer, etc. The user plane protocol layer can include at least one of the following: a service data adaptation protocol (SDAP) layer, a PDCP layer, an RLC layer, a MAC layer, or a physical layer, etc.
[0182] In a possible scenario, the RAN device 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 6th generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc. The RAN device can be a macro base station (such as the RAN device 110a in FIG. 3), a micro base station or an indoor station (such as the RAN device 110b in FIG. 3), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the RAN node can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, the access network device in a vehicle to everything (V2X) technology can be a road side unit (RSU).
[0183] In another possible scenario, a plurality of RAN devices cooperate as node devices to assist a terminal to implement wireless access. Different RAN devices respectively implement part of the functions of a base station. For example, the RAN device can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc.
[0184] As an implementation, as shown in (a) of FIG. 5, the gNB is divided into a CU-CP and a CU-UP. Among them, the CU-CP and the CU-UP communicate through an E1 interface, the CU-CP is deployed with a radio resource control (RRC) layer in the protocol stack and a control plane (CP) of a PDCP layer. The CU-UP is deployed with a service data adaptation protocol (SDAP) layer and a user plane (UP) of a PDCP layer. The CU-CP and the CU-UP respectively communicate with the DU through an F1-C interface and an F1-U interface. The DU is deployed with a radio link control (RLC) layer, a media access control (MAC) layer, and a physical layer (PHY) in the protocol stack. Therefore, the CU-CP has processing capability of the RRC and the control plane of the PDCP. The CU-UP has processing capability of the user plane of the SDAP and processing capability of the user plane of the PDCP. The DU has processing capability of the RLC, the MAC, and the PHY. It can be understood that the above-mentioned splitting of functions is only an example and does not constitute a limitation on the CU and the DU.
[0185] The CU and the DU can be separately arranged or can be included in the same network element, for example, a baseband unit (BBU). The CU node and the DU node split the protocol layers of the gNB, the functions of part of the protocol layers are placed in the CU for centralized control, and the rest or all of the protocol layer functions are distributed in the DU and controlled by the CU.
[0186] As an implementation manner, as shown in (b) of FIG. 5, the CU is deployed with a radio resource control (RRC) layer, a PDCP layer, and a service data adaptation protocol (SDAP) layer in a protocol stack; and the DU is deployed with a radio link control (RLC) layer, a media access control (MAC) layer, and a physical layer (PHY) in the protocol stack. Thus, the CU has processing capability of RRC, PDCP, and SDAP. The DU has processing capability of RLC, MAC, and PHY. It can be understood that the above-mentioned splitting of functions is only an example and does not constitute a limitation on the CU and the DU. The RU can be included in a radio frequency device or a radio frequency unit, for example, included in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).
[0187] For a network element in the ORAN system and a corresponding relationship of protocol layer functions that can be implemented by the network element, refer to the following Table 4:
[0188] Table 4
[0189] As shown in FIG. 6, FIG. 6 is an example diagram illustrating an O-RAN system, which can include other components in addition to the components shown in FIG. 4A and FIG. 4B.
[0190] As shown in FIG. 6, a radio access network device (RAN, which can be an eNB or a gNB or a next-generation access network device gNB) communicates with a core network through a backhaul and communicates with a user equipment (UE) through an air interface.
[0191] Specifically, a baseband unit (BBU) in the access network device communicates with the core network through a backhaul, and a radio unit (RU) in the radio access network device communicates with at least one terminal through an air interface. The BBU communicates with at least one RU through a front haul, and the BBU and the RU can be co-located or not.
[0192] The BBU includes at least one control unit (CU) and at least one distributed unit (DU), which can communicate through at least one midhaul link.
[0193] FIG. 7 is a diagram illustrating a network element function split and protocol layer structure of an O-RAN device.
[0194] In some examples, the CU is a logical node that carries a radio resource control (RRC) layer, a service data adaptation protocol (SDAP) layer, a packet data convergence protocol (PDCP) layer, and other control functions of a radio access network device. The CU is connected to network nodes such as a core network through some interfaces, which can be E2 interfaces or the like. Optionally, the CU can have part of the functions of the core network. The CU (e.g., the PDCP layer and higher layers) is connected to the DU (e.g., the RLC layer and lower layers) through some interfaces, which can be F1 interfaces or the like. In some examples, these interfaces (e.g., the F1 interface) can provide control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transmission, etc.). The F1AP is an application protocol of the F1 interface, which defines signaling procedures of the F1 in some examples. The F1 interface supports a control plane F1-C and a user plane F1-U.
[0195] In some examples, the CU can be split into a CU-CP (control unit-control plane) and a CU-UP (control unit-user plane), where the CU-CP is a logical node carrying the RRC layer and the PDCP-C (Control plane part of PDCP) layer, used to implement the control plane function of the CU. The CU-CP can interact with a network element in the core network used to implement the control plane function. The network element in the core network used to implement the control plane function can be an access and mobility function network element, such as an AMF network element in a 5G system. The AMF network element is used to be responsible for mobility management in the mobile network, such as location update of the terminal device, registration network of the terminal device, handover of the terminal device, etc. The CU-UP is a logical node carrying the SDAP layer and the PDCP-U (user plane part of PDCP) layer, used to implement the user plane function of the CU. The CU-UP can interact with a network element in the core network used to implement the user plane function. The network element in the core network used to implement the user plane function, for example, a UPF (User Plane Function) in a 5G system, is used to be responsible for forwarding and receiving data in the terminal device. The above configuration of the CU and the DU is only an example, and the CU and the DU can also be configured to have other functions according to needs. For example, the CU or the DU can be configured to have more protocol layer functions, or the CU or the DU can be configured to have partial processing functions of the protocol layer. For example, part of the functions of the RLC layer and the functions of the protocol layer above the RLC layer are arranged in the CU, and the remaining functions of the RLC layer and the functions of the protocol layer below the RLC layer are arranged in the DU. For another example, the functions of the CU or the DU can be divided according to the service type or other system requirements, for example, according to the delay, the functions that need to meet the delay requirement are arranged in the DU, and the functions that do not need to meet the delay requirement are arranged in the CU.
[0196] In some examples, the DU is a logical node carrying a radio link control (RLC) layer, a medium access control (MAC) layer, a higher physical layer (higher PHY) layer, and other functions. In some examples, the DU can control at least one RU. The DU is connected to the RU through some interfaces, which can be a front-haul interface.
[0197] In some examples, a CU can have no PDCP layer, i.e., only include RRC layer. CU-CP has no PDCP-C. CU-UP can have no PDCP-U, or no CU-UP at all. In some examples, a DU can have no RLC layer, only MAC and higher PHY layer. Also, in some examples, a CU can only include a DU.
[0198] In some examples, Higher PHY layer includes parts of PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc. processing functions. In some examples, RU is a logical node that hosts lower physical layer (Lower PHY) and radio frequency (RF) processing. In some examples, RU can be a 3GPP transmission reception point (TRP) or a remote radio head (RRH) or other similar functional entity. In some examples, Low-PHY includes parts of PHY processing, such as fast Fourier transform (FFT), inverse fast Fourier transformation (IFFT), digital beamforming and filtering, etc. processing functions. RU communicates with one or more UEs over a wireless link.
[0199] The DU and the RU can be co-located or not. The DU and the RU exchange control plane information and user plane information via a lower-layer split-control, user and synchronization (LLS-CUS) interface over a fronthaul link. The LLS-CUS can include a LLS-C interface and a LLS-U interface that provide a control plane (C-Plane) and a user plane (U-Plane), respectively. In some examples, the control plane (C-Plane) refers to real-time control between the DU and the RU. The DU and the RU exchange management information via a LLS-M interface of the fronthaul link, and the management plane (M-Plane) refers to non-real-time management operation between the DU and the RU. The DU and the RU can cooperate to jointly implement the functions of the PHY layer. One DU can be connected to one or more RUs. The functions of the DU and the RU can be configured in multiple ways according to design. For example, the DU is configured to implement baseband functions, and the RU is configured to implement intermediate radio frequency functions. For another example, the DU is configured to implement high-layer functions in the PHY layer, and the RU is configured to implement low-layer functions in the PHY layer or implement the low-layer functions and radio frequency functions. The high-layer functions in the PHY layer can include a part of functions of the PHY layer that are closer to the MAC layer, and the low-layer functions in the PHY layer can include another part of functions of the PHY layer that are closer to the intermediate radio frequency side.
[0200] Meanwhile, the O-RAN system can also include the following functions / nodes, as shown in Table 5:
[0201] Table 5
[0202] For the fusion sensing service scenario, a new module, which can be referred to as a sensing unit (SU) for example, can be introduced at the base station side. The name does not constitute a limitation, and can be any other name. As shown in (a) of FIG. 8, the SU can be a function or entity within the base station, or as shown in (b) of FIG. 8, the SU can also be a function or entity outside the base station, responsible for performing sensing-related functions.
[0203] The SU can be connected (directly or indirectly) to a core network element SF for interaction of related sensing requirements;
[0204] The SU can be connected to core network elements such as AMF / UPF or CUs / DUs / RUs for transmission of sensing-related information or data.
[0205] As shown in (a) of FIG. 8, the SU is an entity or unit at the base station side, connected to the base station through an interface similar to the Xn interface. The base station can include a CU and a DU.
[0206] As shown in (b) of FIG. 8, the SU is a function in the base station, connected to the CU through an interface similar to the F1 interface (such as F1-S-C), and together constitutes a RAN device.
[0207] Optionally, the SU can also communicate with the terminal through an S-Uu interface. As shown in FIG. 8, the DU can communicate with the terminal.
[0208] The SU can be an alternative to the SF deployed on the RAN side, or the SU can be a module independent of the SF, and can perform all or part of the functions of the SF mentioned in the present application.
[0209] In the embodiments of the present application, the specific structure of the execution subject of the sensing communication method is not particularly limited, as long as the program recording the code of the sensing communication method of the present application can be run to communicate according to the communication method of the present application. For example, the execution subject of the sensing communication method provided by the present application can be a functional module capable of calling and executing the program in the first network element, or a communication device applied to the first network element, such as a chip, a chip system, an integrated circuit, etc. These chips, chip systems, and integrated circuits can be arranged in the internal of the first network element, or can be independent of the first network element, which is not limited in the present application. Or execute part of the steps, and do not execute all the steps. The network element name in the present application does not limit it, and the corresponding function can be realized.
[0210] As shown in FIG. 9, the present application provides a sensing communication method, which comprises:
[0211] Step 901, the first network element determines the first information of the first terminal.
[0212] For example, the first information indicates that the first terminal is allowed to participate in the sensing task or is not allowed to participate in the sensing task.
[0213] As an example, the first network element can be a sensing network element, or a radio access network device, or the first network element is a CU or a DU in the radio access network device, or the first network element is a first module corresponding to the radio access network device, i.e. the SU.
[0214] As an example, the first terminal can be any terminal, or the first terminal can be the terminal determined by the first network element to participate in the sensing task.
[0215] For example, the first information can be a first terminal's sensing authorization information (Authorization), which can also be referred to as a first terminal's sensing consent information (such as consent) or sensing permission information or sensing confirmation information or sensing agreement information or sensing informed information. The first terminal's sensing authorization information is used to confirm whether the first terminal is allowed to participate in the sensing task. Or the first information can be an indication information indicating whether the first terminal is allowed to participate in the sensing task. For example, the first information can also include one or more indication information. For example, the first information can include a first indication information, and can also include a second indication information, or the first information includes the first indication information and the second indication information.
[0216] As an example, the first information includes any one or more of the following:
[0217] a first indication information indicating whether the first terminal is allowed to participate in the sensing task;
[0218] a second indication information indicating whether the first terminal is allowed to participate in the sensing task of a specific sensing mode;
[0219] a third indication information indicating whether the first terminal's communication signal is allowed to be acquired by the sensing task;
[0220] a fourth indication information indicating whether the first terminal's location information is allowed to be acquired by the sensing service;
[0221] a fifth indication information indicating whether the first terminal authorizes the timer of the sensing service or whether the first terminal subscribes to the result of the sensing task participated by the first terminal.
[0222] For example, the second indication information can be one or more information indicating specific sensing mode. If the one or more information indicating specific sensing mode is included in the sensing authorization information of the first terminal, it can be considered that the first terminal allows to participate in the sensing task in the one or more specific sensing mode. If the one or more information indicating specific sensing mode is not included in the sensing authorization information of the first terminal, it can be considered that the first terminal allows to participate in the sensing task in all sensing mode related to the terminal. For example, the first field can be used to indicate that the first terminal allows to participate in the sensing task in the terminal spontaneous self-reception mode, the second field can be used to indicate that the first terminal allows to participate in the sensing task in the base station sending terminal receiving mode, and the third field can be used to indicate that the first terminal allows to participate in the sensing task in the terminal sending base station receiving mode. If the second indication information is the first field and the third field, it indicates that the first terminal allows to participate in the sensing task in the terminal spontaneous self-reception mode and the terminal sending base station receiving mode, but does not allow to participate in the sensing task in the base station sending terminal receiving mode. Alternatively, the second indication information can include an indication related to one or more specific sensing mode. For example, the second indication information is a bitmap, or a bit string, where each bit indicates whether a specific sensing mode is allowed. For example, the first bit indicates whether the terminal spontaneous self-reception mode is allowed, the second bit indicates whether the terminal sending base station receiving mode is allowed, and the third bit indicates whether the base station sending terminal receiving mode is allowed. If the corresponding bit is set to 1, it indicates that the specific sensing mode is allowed, and if the corresponding bit is set to 0, it indicates that the specific sensing mode is not allowed. Alternatively, the content of the second indication information can be as follows: {{terminal spontaneous self-reception mode, 1}, {terminal sending base station receiving mode, 0}, {base station sending terminal receiving mode, 1}}, which indicates that the first terminal allows to participate in the sensing task in the terminal spontaneous self-reception mode and the base station spontaneous terminal receiving mode, but does not allow to participate in the sensing task in the terminal sending base station receiving mode. Wherein "1" means allowed, and "0" means not allowed.
[0223] As an example, the sensing authorization information of the first terminal can also be reported to the SF or the radio access network device together with the sensing capability of the first terminal. For example, the sensing capability of the first terminal indicates whether the first terminal has sensing capability.
[0224] For example, the communication signal of the first terminal includes any one or more of the following: SRS of the first terminal; uplink telemetry signal of the first terminal; measurement signal of the first terminal.
[0225] For example, whether the communication signal of the first terminal is allowed to be acquired by the sensing task can refer to whether the SRS of the first terminal can be used by the radio access network device to collect and process to generate the sensing result, or whether the communication signal of the first terminal is allowed to be acquired by the sensing task can refer to whether the uplink data signal of the first terminal can be used by the radio access network device to collect and process to generate the sensing result. Or, whether the communication signal of the first terminal is allowed to be acquired by the sensing task can refer to whether the measurement signal of the first terminal can be used for sensing data collection.
[0226] For example, the specific sensing mode can refer to one or more of the following sensing modes: terminal-to-base station reception, base station-to-terminal reception, terminal self-transmission and self-reception, or terminal A-to-terminal B reception.
[0227] For example, the sensing task that the first terminal is allowed / not allowed to participate in can be a general meaning, i.e., the first terminal is allowed / not allowed to participate in “any sensing task”, which can be referred to as a sensing service. For example, the first terminal is allowed / not allowed to participate in the sensing service can refer to the sensing task that the first terminal is allowed / not allowed to participate in.
[0228] For example, the sensing task that the first terminal is allowed / not allowed to participate in can be a specific meaning, i.e., the first terminal is allowed / not allowed to participate in a specific sensing task, or a “sensing task in a specific sensing mode”. The sensing task at this time can also be regarded as a sensing service. The sensing task in the embodiments of the present application can also be replaced by a sensing service or a sensing service or a sensing session, etc.
[0229] For example, the first terminal is allowed to participate in the sensing task in the terminal self-transmission and self-reception measurement mode, or the first terminal is allowed to participate in the sensing task in the terminal-to-base station reception measurement mode. For example, the first terminal is allowed to participate in sensing task 1, but is not allowed to participate in sensing task 2.
[0230] For example, whether the location information of the first terminal can be acquired by the sensing service can include whether the cell information / positioning result of the first terminal can be acquired by the sensing service. That is, if the location information of the first terminal can be acquired by the sensing task, it can be considered that the first terminal is allowed to perform any sensing task or perform a specific sensing task. If the location information of the first terminal cannot be acquired by the sensing task, it can be considered that the first terminal is not allowed to perform any sensing task.
[0231] As an example, if the first indication information indicates that the first terminal is allowed to participate in the sensing task, it can be considered that the first terminal is allowed to participate in the sensing task if the first indication information is included in the sensing authorization information.
[0232] Or as an example, if the first indication information indicates that the first terminal is not allowed to participate in the sensing task, it can be considered that the first terminal is allowed to participate in the sensing task if the first indication information is included in the sensing authorization information.
[0233] Alternatively, the first indication information can be a first indicator or a second indicator. The first indicator is used to indicate that the first terminal is allowed to participate in the sensing task. The second indicator is used to indicate that the first terminal is not allowed to participate in the sensing task.
[0234] As an example, if the second indication information indicates that the first terminal is allowed to participate in the sensing task of a specific sensing mode, it can be considered that the first terminal is allowed to participate in the sensing task and the first terminal is allowed to participate in the sensing task of the specific sensing mode if the second indication information is included in the sensing authorization information. Or as an example, if the second indication information indicates that the first terminal is not allowed to participate in the sensing task except for the specific sensing mode, it can be considered that the first terminal is allowed to participate in the sensing task but is not allowed to participate in the sensing task except for the specific sensing mode if the second indication information is included in the sensing authorization information. For example, if the specific sensing mode indicated by the second indication information is the terminal self-initiated self-reception mode, the first network element can determine that the first terminal is not allowed to participate in the sensing task except for the terminal self-initiated self-reception mode.
[0235] Alternatively, the second indication information can include a third indicator and a fourth indicator, wherein the third indicator is used to indicate that the terminal is allowed to participate in the sensing task of a specific sensing mode. The fourth indicator is used to indicate that the terminal is not allowed to participate in the sensing task of the specific sensing mode.
[0236] As an example, if the third indication information indicates that the communication signal of the first terminal is allowed to perform the sensing task, it can be considered that the first terminal is allowed to participate in the sensing task if the third indication information is included in the sensing authorization information. Or as an example, if the third indication information indicates that the communication signal of the first terminal is not allowed to perform the sensing task, it can be considered that the first terminal is not allowed to participate in the sensing task if the third indication information is included in the sensing authorization information.
[0237] Alternatively, the third indication information can be a fifth indicator or a sixth indicator, wherein the fifth indicator is used to indicate that the communication signal of the first terminal is allowed to perform the sensing task. The sixth indicator is used to indicate that the communication signal of the first terminal is not allowed to perform the sensing task.
[0238] As an example, the third indication information can be indication information 1, if the indication information 1 is used to indicate that the SRS of the first terminal can be used by the access network device to collect and process to generate the sensing result, if the third indication information is included in the sensing authorization information, it can be considered that the first terminal is allowed to participate in the sensing task. Or as an example, if the indication information 1 indicates that the SRS of the first terminal cannot be used by the access network device to collect and process to generate the sensing result, if the third indication information is included in the sensing authorization information, it can be considered that the first terminal is not allowed to participate in the sensing task.
[0239] As an example, the third indication information can be indication information 2, if the indication information 2 indicates that the uplink telemetry signal of the first terminal can be used by the access network device to collect and process to generate the sensing result, if the indication information 2 is included in the sensing authorization information, it can be considered that the first terminal is allowed to participate in the sensing task. Or as an example, if the indication information 2 indicates that the uplink telemetry signal of the first terminal cannot be used by the access network device to collect and process to generate the sensing result, if the indication information 2 is included in the sensing authorization information, it can be considered that the first terminal is not allowed to participate in the sensing task.
[0240] As an example, the third indication information can be indication information 3, and the indication information 3 is used to indicate that the measurement report of the first terminal can be used for sensing data collection, if the indication information 3 is included in the sensing authorization information, it can be considered that the first terminal is allowed to participate in the sensing task. Or as an example, if the indication information 3 indicates that the measurement report of the first terminal cannot be used for sensing data collection, if the indication information 3 is included in the sensing authorization information, it can be considered that the first terminal is not allowed to participate in the sensing task.
[0241] As an example, if the fourth indication information indicates that the location information of the first terminal can be obtained by the sensing task, if the fourth indication information is included in the sensing authorization information, it can be considered that the first terminal is allowed to participate in the sensing task. Or as an example, if the fourth indication information indicates that the location information of the first terminal cannot be obtained by the sensing task, if the fourth indication information is included in the sensing authorization information, it can be considered that the first terminal is not allowed to participate in the sensing task.
[0242] As an example, whether the location information of the first terminal can be obtained by the sensing task can include whether the cell information / positioning result of the first terminal can be obtained by the sensing service.
[0243] Or, the fourth indication information can be a thirteenth indicator or a fourteenth indicator, wherein the thirteenth indicator is used to indicate that the location information of the first terminal can be obtained by the sensing task. The fourteenth indicator is used to indicate that the location information of the first terminal cannot be obtained by the sensing task.
[0244] As an example, if the cell information / positioning result of the first terminal is included in the perception authorization information and can be acquired by the perception service, it can be considered that the first terminal is allowed to participate in the perception service. Or as an example, if the cell information / positioning result of the first terminal is indicated in the perception authorization information and cannot be acquired by the perception service, it can be considered that the first terminal is not allowed to participate in the perception service.
[0245] As an example, if the timer of the first terminal authorized for the perception task or the result of the perception task that the first terminal subscribes to is indicated by the fifth indication information, it can be considered that the first terminal is allowed to participate in the perception task if the fifth indication information is included in the perception authorization information. Or as an example, if the timer of the first terminal not authorized for the perception task or the result of the perception task that the first terminal does not subscribe to is indicated by the fifth indication information, it can be considered that the first terminal is not allowed to participate in the perception task if the fifth indication information is included in the perception authorization information.
[0246] As an example, the first network element determines whether the first terminal is allowed to participate in the perception task according to one or more indication information in the perception authorization information, comprising:
[0247] If one or more indication information indicating that the first terminal is allowed to participate in the perception task is included in the perception authorization information, the first network element determines that the first terminal is allowed to participate in the perception task.
[0248] If one or more indication information indicating that the first terminal is not allowed to participate in the perception task is included in the perception authorization information, the first network element determines that the first terminal is not allowed to participate in the perception task.
[0249] For example, if the first indication information indicating that the first terminal is allowed to perform the perception service is included in the perception authorization information, it can be determined that the first terminal is allowed to participate in the perception task.
[0250] For example, if the fifth indication information indicating that the location information of the first terminal can be acquired by the perception task is included in the perception authorization information, it can be determined that the first terminal is allowed to participate in the perception task.
[0251] For example, if the first indication information and the fifth indication information are included in the perception authorization information, it can be determined that the first terminal is allowed to participate in the perception task.
[0252] For example, if the second indication information indicating that the first terminal is allowed to participate in the base station-to-terminal perception communication mode is included in the perception authorization information, it can be determined that the first terminal is allowed to participate in the perception task and the base station-to-terminal perception communication mode.
[0253] As an example, if the second indication information indicates that the specific sensing mode in which the first terminal is allowed to participate is base station transmit terminal receive and terminal transmit base station receive, then the first terminal can participate in the sensing task according to the specific sensing mode in which the first terminal is allowed to participate for the first network element.
[0254] In step 902, the first information indicates that the first terminal is allowed to participate in the sensing task, and the first network element performs the sensing service through the first terminal.
[0255] The manner in which the first network element performs the sensing service through the first terminal can refer to the description in the prior art, and the embodiments of the present application do not limit this.
[0256] As an example, taking the first network element as a wireless access network device as an example, if the first network element determines that the first terminal is allowed to participate in the sensing task according to the first information, the wireless access network device can configure resources related to sensing for the first terminal to send or receive sensing signals.
[0257] As an example, if the first network element determines that the first terminal is allowed to participate in the sensing task in a specific sensing mode according to the first information, the first network element triggers the first terminal to perform sensing measurement in the specific sensing mode allowed by the first terminal.
[0258] As an example, taking the first network element as a SF as an example, if the first network element determines that the first terminal is allowed to participate in the sensing task according to the first information, the SF can send a first message to the wireless access network device or the first terminal, for the first terminal to perform the sensing task, or for the first terminal to send or receive sensing signals.
[0259] The method provided by the embodiments of the present application first determines the first information indicating whether the first terminal is allowed to participate in the sensing task before the first network element performs the sensing measurement through the first terminal, and then determines that if the first terminal is allowed to participate in the sensing task, the sensing measurement will be performed through the first terminal to execute the subsequent sensing related process. In this way, the situation of infringing the rights and interests of the terminal caused by directly participating in the sensing task through the first terminal without the authorization of the first terminal can be avoided, so that the execution of the sensing task through the first terminal conforms to the will of the first terminal, and the normal performance of the sensing work can be ensured.
[0260] In a possible embodiment of the present application, the first network element can obtain the first information of the first terminal from other network elements (such as AMF network element, UDM network element, SF network element or wireless access network device), or obtain the first information of the first terminal from the first terminal.
[0261] For example, the first network element determines to select the first terminal to participate in the sensing task, and the first network element can send a request message to the first terminal to request the first terminal to confirm whether the first terminal allows to participate in the sensing task. The first terminal can return a response message to the first network element according to the sensing authorization information pre-configured by the first terminal or the demand of the first terminal. The response message is used to indicate the judgment result of whether the first terminal allows to participate in the sensing task. For example, on one hand, the first terminal can determine to allow to participate in the sensing task according to the sensing authorization information of the first terminal or the situation of the first terminal, and send the first information or the sensing authorization information indicating that the first terminal allows to participate in the sensing task. If the first terminal determines not to allow to participate in the sensing task according to the sensing authorization information of the first terminal or the situation of the first terminal, the first terminal sends the first information or the sensing authorization information indicating that the first terminal does not allow to participate in the sensing task.
[0262] In a possible embodiment of the present application, before the first network element determines the first information, the method provided by the embodiment of the present application further includes: the first network element determines the first terminal participating in the sensing task.
[0263] As an example, the first network element determines the first terminal participating in the sensing task can be implemented by the following way:
[0264] For example, the first network element can select a terminal (for example, the first terminal) from one or more terminals to participate in the sensing task according to the position information of the one or more terminals. Wherein, the one or more terminals are located in the area served by the SF network element or the radio access network device.
[0265] For example, the first network element can select a terminal (for example, the first terminal) from one or more terminals to participate in the sensing task in the case that it is determined that there is a sensing measurement demand. For example, the sensing measurement demand can refer to sensing measurement on a target object based on a sensing mode related to the terminal.
[0266] For example, the first terminal can be selected by the first network element, or can be provided by other network elements. For example, taking the first network element as the radio access network device, the radio access network device can select the first terminal as the terminal participating in the sensing task based on the indication of the SF. Or taking the first network element as the SF, the SF can determine one or more terminals by itself, and select a terminal from the one or more terminals to determine as the first terminal. Or the SF can also obtain one or more terminals that can participate in the sensing task from the radio access network device, and then select the first terminal from the one or more terminals that can participate in the sensing task.
[0267] It can be understood that, before the first network element determines the first information, the first network element determines the first terminal participating in the sensing task first. At this time, although the first network element determines the first terminal that can participate in the sensing task, the first network element does not know whether the first terminal allows to participate in the sensing task at this time. Therefore, in the above scheme, after the first network element determines that the first terminal participates in the sensing task, the first network element determines whether the first terminal allows to participate in the sensing task according to the first information of the first terminal. If the first terminal allows to participate in the sensing task, it is determined that the sensing measurement is performed through the first terminal, that is, subsequent sensing related processes are performed through the first terminal, such as obtaining the sensing measurement result of the target object by using the first terminal. In this way, subsequent participation of the first terminal in the sensing task does not infringe the rights and interests of the first terminal and can ensure that the sensing work is normally performed.
[0268] In a possible embodiment of the present application, the first network element has the first information of the first terminal.
[0269] As an example, before the first network element determines the first information of the first terminal, the method provided by the embodiments of the present application can further include: the first network element obtains the first information of the first terminal from a third network element.
[0270] For example, the third network element can be a sensing authorization network element (Sensing Authorization Function, SaF) or an AMF network element or an AF network element, etc. Of course, the third network element can also be the first terminal.
[0271] For example, the first network element can request the third network element to provide the first information of the first terminal, or the SaF network element or the AMF network element or the AF network element sends the first information of the first terminal to the radio access network device or the SF.
[0272] As an example, when the first network element is a DU in the radio access network device, the DU in the radio access network device can obtain the first information of the first terminal from the CU or the SU in the radio access network device.
[0273] The communication between the DU and the CU or the DU and the SU can refer to the description as shown in FIG. 8, which will not be described here.
[0274] As an example, when the first network element is a SU in the radio access network device, the SU in the radio access network device can obtain the first information of the first terminal from the CU or the DU.
[0275] As an example, when the first network element is a CU in the radio access network device, the CU in the radio access network device can obtain the first information of the first terminal from the DU or the SU.
[0276] In the above solution, since the first information of the first terminal is stored in the first network element, the first network element can determine whether the first terminal is allowed to participate in the sensing task according to the first information of the first terminal when the first network element needs to perform sensing measurement, and then the first network element can determine the first terminal as a terminal for performing sensing measurement, or the first network element determines the first terminal participating in the sensing task, and then determines whether the first terminal is allowed to participate in the sensing task according to the first information of the first terminal.
[0277] For example, the first network element is a radio access network device, the first network element can determine a terminal allowed to participate in the sensing task as the first terminal according to the first information of one or more terminals based on the sensing measurement request of the SF. Or the first network element can determine whether the first terminal is allowed to participate in the sensing task according to the first information of the first terminal based on the identifier of the first terminal carried in the sensing measurement request of the SF.
[0278] In a possible embodiment of the present application, the first network element determines the first information of the first terminal, including: the first network element sends a first request message, and the first request message is used to request the first information of the first terminal. The first network element receives the first information from a second network element.
[0279] For example, the first network element can send a first request message to a second network element, and the second network element can be a network element storing sensing authorization information of the first terminal. For example, the second network element can be a UDM or an SF or an AF or a SaF or a radio access network device.
[0280] For example, the first network element is a radio access network device, and the second network element can be a UDM or an SF or an AF or a SaF or an AMF or the like having the sensing authorization information of the first terminal. Or the second network element does not have the sensing authorization information of the first terminal, but the second network element can obtain the sensing authorization information of the first terminal based on the first request message. For example, the second network element can obtain the sensing authorization information of the first terminal from the first terminal based on the first request message.
[0281] For example, the first network element is an SF, and the second network element can be a UDM or a radio access network device or an AF or a SaF or an AMF or the like having the sensing authorization information of the first terminal. Or the second network element does not have the sensing authorization information of the first terminal, but the second network element can obtain the sensing authorization information of the first terminal based on the first request message. For example, the second network element can obtain the sensing authorization information of the first terminal from the first terminal based on the first request message.
[0282] For example, taking the first network element as a DU / SU as an example, the second network element can be a UDM or a CU of a radio access network device or an AF or a SaF or an AMF, etc. which has the perception authorization information of the first terminal. Or the second network element does not have the perception authorization information of the first terminal, but the second network element can obtain the perception authorization information of the first terminal based on the first request message. For example, the second network element can be a CU, and after the DU or the SU sends the first request message to the CU, the CU can obtain the perception authorization information of the first terminal from the first terminal or from the SF or the UMD based on the first request message.
[0283] The first network element can actively obtain the perception authorization information of the first terminal from the second network element, or the SaF or the AMF or the AF actively pushes the perception authorization information of the first terminal to the access network device or the SF. Of course, the second network element can also be the first terminal.
[0284] As an example, the first request message includes the identification information of the first terminal. Optionally, the first request message can also include indication information, which is used to request the first information of the first terminal. Or the indication information is used to indicate the second network element to confirm whether the first terminal is allowed to participate in the perception business.
[0285] The identification information of the first terminal is used to identify the first terminal.
[0286] In this scheme, after the first network element determines the first terminal participating in the perception task or before determining the first terminal participating in the perception task, it is necessary to confirm the authorization information of the first terminal to the node (such as the second network element) storing the perception authorization information of the first terminal, so as to determine whether the first terminal participates in the perception task based on the perception authorization information of the first terminal.
[0287] For example, the first network element confirms that the first terminal is allowed to participate in the perception task according to the perception authorization information of the first terminal, and can determine to perform perception measurement through the first terminal. If the first network element confirms that the first terminal is not allowed to participate in the perception task according to the perception authorization information of the first terminal, the first terminal will not be selected to participate in the perception task, i.e. the first terminal will not be used for perception measurement.
[0288] For example, taking the first network element as a radio access network device as an example, after the first network element selects the first terminal to participate in the perception task according to the perception authorization information of the first terminal, the radio access network device can further configure the perception reference resource for the first terminal.
[0289] For example, taking the first network element as the SF as an example, after the first network element selects the first terminal to participate in the sensing task according to the sensing authorization information of the first terminal, the SF can further include: the SF sends a message 1 to the radio access network device. The message 1 is used for the radio access network device to determine that the first terminal is allowed to participate in the sensing task, so as to configure the first terminal with sensing-related resources, such as resources for sending / receiving sensing signals. For example, the message 1 includes indication information to indicate that the first terminal is allowed to participate in the sensing task, so as to facilitate the radio access network device to confirm that the first terminal is allowed to participate in the sensing task according to the indication information, and thus configure the first terminal with sensing-related resources. Or the message 1 can include indication information, which is used to indicate that the first terminal is configured with sensing-related resources. At this time, for the radio access network device, it can be implicitly determined that the first terminal is allowed to participate in the sensing task.
[0290] In a possible embodiment of the present application, the method provided by the embodiments of the present application can further include: the first network element acquires second information, and the second information is used to determine information of one or more public land mobile networks (PLMNs) to which the sensing authorization information is applicable. The first information indicates that the first terminal is allowed to participate in the sensing task, and the first network element performs the sensing task through the first terminal, including: the first information indicates that the first terminal is allowed to participate in the sensing task, and the first network element performs the sensing task through the first terminal in any PLMN network to which the sensing authorization information is applicable. By determining the information of one or more public land mobile networks to which the sensing authorization information is applicable, it can be avoided that the first terminal participates in the sensing task in the PLMN network to which the sensing authorization information of the first terminal is not applicable.
[0291] For example, the second information can be information of one or more PLMN networks corresponding to the sensing authorization information, and the information of the one or more PLMNs is used to determine the PLMN network to which the sensing authorization information is applicable. For example, the one or more PLMN networks corresponding to the sensing authorization information can be information of the PLMN network to which the sensing authorization information is applicable, or information of the PLMN network to which the sensing authorization information is not applicable. If the one or more PLMN networks corresponding to the sensing authorization information is information of the PLMN network to which the sensing authorization information is not applicable, the first network element can determine that the sensing authorization information of the first terminal is applicable to other PLMNs except the one or more PLMNs to which the sensing authorization information is not applicable.
[0292] For example, the second information can be identification information of the first terminal, or the second information can be information indicating that the sensing authorization information of the first terminal is applicable to any PLMN network. For example, if the second information indicates that the sensing authorization information does not correspond to information of any PLMN network, it can be considered that the sensing authorization information is applicable to any network.
[0293] For example, the awareness authorization information of the first terminal further indicates information of one or more PLMN networks corresponding to the awareness authorization information, and the information of the one or more PLMN networks is used to indicate the PLMN network to which the awareness authorization information is applicable.
[0294] For example, the awareness authorization information of the first terminal can be associated with information of one or more PLMN networks, or the awareness authorization information of the first terminal can include information of one or more PLMN networks, which can indicate that the awareness authorization information of the first terminal is applicable to the one or more PLMN networks or is not applicable to the one or more PLMN networks. Or if the awareness authorization information of the first terminal is not associated with any PLMN network or does not include information of any PLMN network, it can be considered that the awareness authorization information of the first terminal is applicable to any PLMN network.
[0295] In a possible embodiment of the present application, the awareness authorization information of the first terminal can further correspond to second information, or the awareness authorization information of the first terminal includes the second information, and the second information is used to indicate information of one or more PLMN networks to which the awareness authorization information of the first terminal is applicable. For example, the second information can be identification information of the first terminal, or the second information can also be indication information indicating that the awareness authorization information of the first terminal is applicable to any PLMN network.
[0296] It can be understood that the second information is used to indicate that the awareness authorization information of the first terminal is terminal-granular, i.e., the awareness authorization information of the first terminal is applicable to any PLMN network, i.e., the awareness authorization information of the first terminal is used to reflect that the first terminal is allowed to participate or is not allowed to participate in the awareness task in any PLMN network. The information of the PLMN corresponding to the awareness authorization information of the first terminal is used to reflect that the awareness authorization information is PLMN-granular, i.e., the awareness authorization information of the first terminal is applicable to the PLMN network indicated by the information of the PLMN.
[0297] The information of the PLMN can be an identifier of the PLMN network, which is used to identify the PLMN network.
[0298] For example, if the information of the PLMN corresponding to the awareness authorization information of the first terminal is the identifier of the PLMN network 1 and the PLMN network 2, it indicates that the awareness authorization information of the first terminal is applicable to the PLMN network 1 and the PLMN network 2, and is not applicable to other networks except the PLMN network 1 and the PLMN network 2.
[0299] As an example, if the first terminal is currently accessing the PLMN network 1, the radio access network device refers to the radio access network device in the PLMN network 1, and the first terminal's awareness authorization information acquired by the first network element is the awareness authorization information corresponding to the first terminal in the PLMN network 1, in other words, the first network element determines whether the first terminal is allowed to participate in the awareness task in the PLMN network 1 according to the awareness authorization information corresponding to the first terminal in the PLMN network 1. If the awareness authorization information corresponding to the first terminal in the PLMN network 1 indicates that the first terminal is allowed to participate in the awareness task, the first network element performs the awareness task in the PLMN network 1 through the first terminal.
[0300] As an example, the awareness authorization information of the first terminal can include PLMN information or identification information of the first terminal. If the awareness authorization information of the first terminal includes the identification information of the first terminal, it can be considered that the awareness authorization information of the first terminal is terminal-granularity. If the awareness authorization information of the first terminal includes the PLMN information, it can be considered that the awareness authorization information of the first terminal is PLMN-granularity. As an example, the PLMN information included in the awareness authorization information of the first terminal can be information of a PLMN network to which the awareness authorization information of the first terminal applies or information of a PLMN network to which the awareness authorization information of the first terminal does not apply.
[0301] It should be noted that if the first terminal is currently accessing the PLMN network 2 and the awareness authorization information of the first terminal acquired by the first network element indicates that the first terminal is not allowed to participate in the awareness task in the PLMN network 2, the first network element determines that the first terminal is not allowed to participate in the awareness task. If the awareness authorization information of the first terminal acquired by the first network element indicates that the first terminal is allowed to participate in the awareness task in the PLMN network 2, the first network element determines that the first terminal is allowed to participate in the awareness task in the PLMN network 2.
[0302] As an example, the awareness authorization information of the first terminal can be the awareness authorization information of the first terminal in a certain PLMN network. Or the awareness authorization information of the first terminal can include the awareness authorization information of the first terminal in multiple different PLMN networks. The contents of the awareness authorization information of the first terminal in the multiple different PLMN networks can be the same or different, which is not limited by the embodiments of the present application. For example, the content of the awareness authorization information of the first terminal in the PLMN network 1 can include first indication information and second indication information. And the content of the awareness authorization information of the first terminal in the PLMN network 2 can include the second indication information and fourth indication information.
[0303] It can be understood that the first terminal can report the corresponding awareness authorization information of the first terminal in one or more PLMN networks to the SaF or the SF or the UDM, that is, the first terminal has specific awareness authorization information in different PLMN networks, or reports a common awareness authorization information. Among them, the common awareness authorization information is the awareness authorization information applicable to any PLMN network of the first terminal. When the first network element requests the awareness authorization information of the first terminal from the second network element, the first network element can provide the information of the PLMN network to the second network element to indicate the second network element to provide the awareness authorization information of the first terminal in the PLMN network indicated by the information of the PLMN network to the first network element. It can be understood that if the second network element determines not to have the awareness authorization information of the first terminal in the PLMN network indicated by the information of the PLMN network, it can be obtained from the first terminal. If the first terminal does not have the awareness authorization information of the first terminal in the PLMN network indicated by the information of the PLMN network, the first terminal can feed back an indication that it does not have the awareness authorization information in the PLMN network, and the second network element can also feed back the indication that the first terminal does not have the awareness authorization information in the PLMN network to the first network element. At this time, for the first network element, since the awareness authorization information of the first terminal in the PLMN network is not obtained, the first terminal cannot perform the awareness task in the PLMN network. If the first terminal does not have the awareness authorization information of the first terminal in the PLMN network indicated by the information of the PLMN network, but the first terminal has the common awareness authorization information, the first terminal can improve the common awareness authorization information. In this way, for the first network element, it can also determine whether the first terminal is allowed to participate in the awareness task in a certain PLMN network according to the common awareness authorization information of the first terminal.
[0304] Generally, the position of the awareness target can be determined through the awareness measurement, and the position of the awareness target is relative to the positions of the sending end and the receiving end of the awareness signal. Since the position of the terminal related to the awareness mode of sending the awareness signal or receiving the echo signal has a greater impact on whether the awareness task is available, how to determine the position information of the terminal and how to obtain it are problems to be solved in the awareness process. Based on this, in a possible implementation manner of the present application, the method provided by the embodiments of the present application can further include: the wireless access network device obtains the position information of the first terminal through the first awareness module, the first module is located inside or outside the access network device, and the first module is configured to perform awareness related functions.
[0305] In a possible embodiment of the present application, the first network element is a first module corresponding to the wireless access network device, for example, the first module can belong to the wireless access network device, or the first module can be an entity or module independent of the wireless access network device, and the method provided by the embodiment of the present application further includes: the first network element sends a second request message to the CU of the wireless access network device, and the second request message is used to request the location information of the first terminal. The first network element receives the location information of the first terminal from the CU.
[0306] As an example, the first module can send the second request message to the CU of the wireless access network device to request the CU to acquire the location information of the first terminal. Then, after receiving the second request message, the CU sends an RRC message to the first terminal to instruct the first terminal to report the location information of the first terminal. After receiving the RRC message, the first terminal can report the location information of the first terminal to the CU or report the location information of the first terminal to the SU through the communication interface between the first terminal and the SU. If the first terminal reports the location information of the first terminal to the CU, the CU reports the location information of the first terminal to the SU.
[0307] As another example, the SU generates a UE location information acquisition message (similar to a NAS message or an RRC inter node message) and forwards the UE location information acquisition message to the first terminal by the CU.
[0308] As an example, the second request message further includes: a precision requirement of the location information, and / or a location information reporting trigger condition / period. In this way, the first terminal can report the location information of the first terminal based on the precision requirement of the location information.
[0309] As an example, if the second request message further includes the precision requirement of the location information, the first terminal provides the location information of the first terminal to the wireless access network device based on the precision requirement of the location information when reporting the location information of the first terminal.
[0310] As an example, if the second request message further includes the location information reporting trigger condition / period, the first terminal can actively provide the location information of the first terminal when the trigger condition / period is met.
[0311] For example, the location information reporting trigger condition can be that the position of the terminal moves more than a certain distance, and then the first terminal can report the location information of the first terminal to the wireless access network device when the position of the terminal moves more than a certain distance.
[0312] For example, the location information reporting period is to report the location information once every 5 seconds, and then the first terminal can report the location information of the first terminal to the wireless access network device every 5 seconds.
[0313] For example, the position information reporting period is 5 seconds when the first terminal is in a moving state or the moving speed is greater than a threshold, or the position information reporting period is 30 seconds when the first terminal is in a stationary state or the moving speed is less than a threshold.
[0314] The above scheme describes that the wireless access network device can obtain the position information of the first terminal based on the SU in the perception process. In a possible embodiment of the present application, the wireless access network device can also obtain the position information of the first terminal in the perception process from the core network. For example, the first network element is a first module corresponding to the wireless access network device, and the method provided in the embodiment of the present application further includes:
[0315] The first network element sends a third request message to the perception network element through a communication interface between the first network element and the perception network element or through the CU of the wireless access network device, and the third request message is used to request to obtain the position information of the first terminal.
[0316] The first network element receives the position information of the first terminal from the perception network element through the communication interface between the first network element and the perception network element or the CU.
[0317] In a possible embodiment of the present application, the position information of the first terminal further includes attributes of the position information and / or a time limit corresponding to the position information. The attributes of the position information are used to indicate whether the position information is position information when the first terminal is stationary or moving. The time limit corresponding to the position information is used to reflect a time period in which the position information of the first terminal is valid.
[0318] Through the interaction between the first module and the SF, the wireless access network device can obtain the position information of the first terminal from the core network (such as LMF).
[0319] For example, after the SF receives the third request message, the SF can request the LMF network element to obtain the position information of the first terminal, and then the LMF network element provides the position information of the first terminal to the SF. Then the SF sends the position information of the first terminal to the SU through the communication interface between the first perception module or the CU.
[0320] In a possible implementation manner of the present application, the method provided in the embodiment of the present application further includes: the first module sends the position information of the first terminal to the DU of the wireless access network device.
[0321] Since the DU determines the sensing data (or also called sensing measurement result), if a point cloud is to be generated, the position coordinates of the sensing target need to be determined, and the position of the sensing target is generated based on the position information of the node that transmits the sensing signal or receives the signal. Therefore, the DU can first determine the relative position of the sensing target relative to the node, and the absolute position of the sensing target can be determined in combination with the position of the node.
[0322] As shown in FIG. 10, FIG. 10 is a specific flowchart of a sensing communication method provided by an embodiment of the present application, and the method comprises:
[0323] In step 1001, the terminal sends sensing authorization information of the terminal. Correspondingly, the SaF receives the sensing authorization information of the terminal from the terminal.
[0324] As an example, in FIG. 10, the terminal can send the sensing authorization information of the terminal to the SaF, and the SaF in FIG. 10 can also be replaced by other network elements, in other words, other network elements collect the sensing authorization information of the terminal. For example, the other network elements can be an application function (application function, AF), or any other network element (SF network element, AMF network element, etc.), or an application server.
[0325] For example, the terminal can send the sensing authorization information of the terminal to the sensing authentication network element in the following ways: 1) the terminal directly reports the sensing authorization information of the terminal; 2) the terminal reports the subscription information of the terminal to the sensing authentication network element, wherein the subscription information of the terminal includes the sensing authorization information of the terminal; and 3) the terminal reports the user service confirmation (used for user confirmation of participating in the sensing task) to the sensing authentication network element.
[0326] As an example, the terminal can send a first message to the sensing authentication network element. The first message includes the sensing authorization information. For example, the first message can be a NAS layer signaling.
[0327] For example, “whether the terminal is allowed to participate in the sensing task” can be a general concept, that is, the sensing task that the terminal is allowed to participate in can refer to any sensing task. For example, the terminal can participate in sensing of sensing task 1 and sensing of sensing task 2.
[0328] For example, the terminal is not allowed to participate in the sensing task can refer to any sensing task that the terminal is not allowed to participate in.
[0329] For example, “whether the terminal is allowed to participate in the sensing task” can be a specific concept, that is, the sensing task that the terminal is allowed to participate in can refer to a specified sensing task. For example, the terminal can participate in sensing of sensing task 1, but cannot participate in sensing of sensing task 2.
[0330] As an example, the terminal can actively send the perception authorization information of the terminal to the perception authentication network element in the case of RRC connected state / powered on.
[0331] As an example, the terminal can send the perception authorization information of the terminal to the access network device or the Saf to which the terminal accesses in the handover process or the context migration process. For example, the perception authorization information of the terminal can be contained in the context of the terminal at this time. The handover process can refer to the process of switching the core network of the terminal or the process of switching the access network device of the terminal.
[0332] As another example, in the process of switching the wireless access network device of the terminal, the source wireless access network device accessed by the terminal can also send the perception authorization information of the terminal to the target access network device of the terminal. For example, the source access network device can send a handover request message (HANDOVER REQUEST message) to the target wireless access network device. The HANDOVER REQUEST message contains the perception authorization information of the terminal.
[0333] As another example, in the scenario of switching the AMF network element of the terminal, if the source AMF network element accessed by the terminal has the perception authorization information of the terminal, the source AMF network element can also provide the perception authorization information of the terminal to the target AMF network element of the terminal. In this way, the wireless access network device of the terminal can subsequently obtain the perception authorization information of the terminal from the target AMF network element.
[0334] As an example, the perception authorization information of the terminal involved in the embodiments of the present application can be terminal granularity or PLMN granularity. The perception authorization information reported by the terminal to the Saf also corresponds to the identification information of the terminal or the information of the PLMN.
[0335] Taking the perception authorization information of the terminal as the PLMN granularity as an example, the PLMN granularity can be understood as that the terminal is allowed to participate in the perception task in the network of a specified PLMN, and does not participate in the perception task in the network of other PLMNs. For the terminal granularity, it can be understood that the terminal is allowed to participate in the perception task in any network.
[0336] For example, if the terminal can access one or more PLMNs, and the terminal has awareness authorization information corresponding to different PLMNs, the awareness authorization information corresponding to different PLMNs of the terminal can be the same or different. If the awareness authorization information corresponding to different PLMNs of the terminal is different, the awareness authorization information of the terminal in PLMN1 indicates that the terminal allows the network of PLMN1 to participate in the sensing task. Therefore, optionally, the awareness authorization information reported by the terminal to the Saf also corresponds to the information of the PLMN, so that the access network device / SF determines which network corresponding to the information of the PLMN indicated by the awareness authorization information reported by the terminal allows the terminal to participate in the sensing task.
[0337] As an example, the above-mentioned sensing authentication network element can also be replaced by an AMF network element or an SMF network element or other network elements in the core network, and the embodiments of the present application do not limit this.
[0338] Step 1002, the Saf sends the awareness authorization information of the terminal. Correspondingly, the wireless access network device receives the awareness authorization information of the terminal.
[0339] As an example, the Saf can send the awareness authorization information of the terminal to the UDM, and then the UDM forwards the awareness authorization information of the terminal to the SF, and then the SF sends the awareness authorization information of the terminal to the wireless access network device.
[0340] As an example, the Saf can actively send the awareness authorization information of the terminal to the wireless access network device. Or the Saf can send the awareness authorization information of the terminal to the wireless access network device based on the request of the wireless access network device.
[0341] Step 1003, the wireless access network device stores the awareness authorization information of the terminal.
[0342] It can be understood that the wireless access network device can serve multiple terminals, so the wireless access network device can obtain and store the awareness authorization information of multiple terminals through the above steps.
[0343] As an example, if the wireless access network device is a split architecture, that is, the wireless access network device includes a CU and a DU, the CU receives the awareness authorization information of the terminal and stores it. Subsequently, in the scenario of determining whether the terminal is allowed to participate in the sensing task, the DU requests the awareness authorization information of the terminal from the CU, and then the CU sends the awareness authorization information of the terminal to the DU. Finally, the DU determines whether the terminal is allowed to participate in the sensing task according to the awareness authorization information of the terminal. Or the CU sends the awareness authorization information to the DU, and the DU stores it, and the embodiments of the present application do not limit this.
[0344] After step 1003, the wireless access network device can confirm whether the first terminal determined by the SF to participate in the perception task is allowed to perform the perception task based on the request of the SF, i.e., steps 1004a-1008a described below, or the wireless access network device confirms whether the terminal can participate in the perception task as a terminal participating in the perception task based on the perception authorization information of the terminal, i.e., steps 1004b-1005b described below.
[0345] Step 1004a: The SF determines the first terminal participating in the perception task.
[0346] For ease of description, the terminal participating in the perception task determined by the SF or the wireless access network device in the embodiments of the present application can be referred to as a perception terminal, which is uniformly described here and will not be described again in the following.
[0347] As an example, the SF can determine the first terminal participating in the perception task in the following manner:
[0348] For example, the SF can determine the first terminal as a perception terminal from one or more terminals according to the location information of the one or more terminals.
[0349] It can be understood that in the case where the SF determines the first terminal participating in the perception task, the SF cannot determine whether the first terminal is allowed to participate in the perception task at this time. Therefore, in order to avoid infringing the rights and interests of the first terminal by performing perception measurement through the first terminal, the SF can also confirm whether the first terminal is allowed to participate in the perception task, such as performing step 1005a described below, from a node (such as a network element of the wireless access network device or the UDM or the SaF or the AF or the first terminal, etc.) storing the perception authorization information of the first terminal when determining the first terminal.
[0350] Step 1004a can not be an explicit step, but an internal implementation of the SF.
[0351] As another example, optionally, before step 1004a, the SF can also send a request message to the wireless access network device, the request message being used to trigger the wireless access network device to select a terminal participating in the perception task. Then the wireless access network device provides the SF with the information of one or more terminals based on the request message, and the information of the terminal can be the identifier of the terminal or the location information of the one or more terminals. In this scenario, step 1004a can be implemented in the following manner: the SF selects a terminal from the information of one or more terminals reported by the wireless access network device as the first terminal participating in the perception task, and then the SF triggers 1005a.
[0352] As another example, before step 1004a, the method can further comprise: the SF sending a request message to the radio access network device, the request message being used to trigger the radio access network device to report information of one or more terminals allowed to participate in the perception task. Then the radio access network device provides the information of the one or more terminals to the SF based on the request message, where the information of the one or more terminals refers to the information of the terminals allowed to participate in the perception task, and the information of the terminal can be an identifier of the terminal or location information of the one or more terminals. In this scenario, step 1004a can be implemented by the following manner: the SF selects a terminal from the information of the one or more terminals reported by the radio access network device as the first terminal participating in the perception task, and then the radio access network device performs step 1007a.
[0353] Step 1005a, the SF sends a first request message to the radio access network device. Correspondingly, the radio access network device receives the first request message from the SF.
[0354] For example, the first request message is used to request the radio access network device to confirm whether the first terminal is allowed to participate in the perception task.
[0355] For example, the CU receives the first request message, and then the CU sends the perception authorization information of the first terminal to the DU, and then the DU performs the following step 1006a.
[0356] As an example, the first request message comprises the identification information of the first terminal. By carrying the identification of the first terminal in the first request message, it is convenient for the radio access network device to confirm which terminal the SF requests to query whether it is allowed to participate in the perception task.
[0357] Step 1006a, the radio access network device confirms whether the first terminal is allowed to participate in the perception task according to the perception authorization information of the first terminal.
[0358] For example, the radio access network device can query the perception authorization information of the first terminal from the perception authorization information of a plurality of terminals stored at the radio access network device according to the identification information of the first terminal. Then, the radio access network device confirms whether the first terminal is allowed to participate in the perception task according to the perception authorization information of the first terminal.
[0359] The process of the radio access network device confirming whether the first terminal is allowed to participate in the perception task according to the perception authorization information of the first terminal can refer to the description in the above embodiments, which will not be described here.
[0360] It can be understood that if the radio access network device determines that the awareness authorization information of the first terminal is not stored locally according to the identity of the first terminal provided by the SF, the radio access network device can obtain the awareness authorization information of the first terminal from the UDM or the SaF. For example, if the above step 1002 is omitted in the actual process, the radio access network device can request the awareness authorization information of the terminal from the SaF after step 1005a to trigger the SaF to perform the action of step 1002.
[0361] Step 1007a, the radio access network device sends a first response message to the SF, and the corresponding SF receives the first response message from the radio access network device.
[0362] For example, the first response message is used for the SF to determine whether the awareness terminal is allowed to participate in the awareness task. For example, the first response message includes first information, and the first information is used to indicate whether the first terminal is allowed to participate in the awareness task.
[0363] As an example, the first information can be the awareness authorization information of the first terminal, or an indication information. It can be understood that if the first information is the awareness authorization information of the first terminal, the above step 1007a can be omitted, that is, after the radio access network device receives the first request message, the radio access network device provides the awareness authorization information of the first terminal to the SF.
[0364] As an example, if the radio access network device determines that the awareness terminal is allowed to participate in the awareness task according to the awareness authorization information of the awareness terminal, the first information sent by the radio access network device to the SF is used to indicate that the first terminal is allowed to participate in the awareness task.
[0365] As an example, if the radio access network device determines that the awareness terminal is not allowed to participate in the awareness task according to the awareness authorization information of the awareness terminal, the first information sent by the radio access network device to the SF is used to indicate that the first terminal is not allowed to participate in the awareness task. In this way, the SF can determine that the first terminal is not allowed to participate in the awareness task, and then perform other actions. For example, the SF can reselect the terminal participating in the awareness task. In this way, the awareness mode related to the terminal can be prevented from not working normally, and the rights and interests of the first terminal can be prevented from being infringed.
[0366] As an example, if the radio access network device determines that the awareness terminal is allowed to participate in the awareness task according to the awareness authorization information of the awareness terminal, the first information sent by the radio access network device to the SF is used to indicate that the first terminal is allowed to participate in the awareness task.
[0367] As an example, if the awareness authorization information of the first terminal further comprises an indication information indicating that the first terminal allows to participate in the sensing task of a specific sensing mode, the first message can further comprise sensing mode indication information, so as to facilitate the SF to determine the sensing mode allowed to be participated in by the first terminal according to the sensing mode indication information. For example, if the indication information indicates that the first terminal supports to participate in the self-initiated and self-collected sensing task, the SF can determine that the first terminal allows to participate in the self-initiated and self-collected sensing task, and thus can send the sensing demand indicating that the first terminal performs the self-initiated and self-collected sensing to the first terminal. For example, if the indication information indicates that the first terminal supports the sensing mode in which the terminal sends the sensing signal and the base station receives the sensing signal, the SF can send the action of triggering the first terminal to send the sensing signal to the first terminal.
[0368] If the wireless access network device confirms that the first terminal allows to participate in the sensing task according to the awareness authorization information of the first terminal in step 1006a, the following step 1008a can be performed. In other words, if the wireless access network device confirms that the first terminal does not allow to participate in the sensing task according to the awareness authorization information of the first terminal in step 1006a, step 1008a can be omitted.
[0369] Optionally, after step 1007a, the SF can further send a request message to the wireless access network device, the request message being used to indicate to configure the sensing-related resource for the first terminal.
[0370] Step 1008a, the wireless access network device configures the resource for the first terminal.
[0371] For example, the resource configured by the wireless access network device for the first terminal is used for the first terminal to send the sensing signal.
[0372] Optionally, the wireless access network device can perform step 1008a based on the request message from the SF indicating to configure the sensing-related resource for the first terminal, or the wireless access network device can decide to perform step 1008a by itself after step 1005a, and optionally, the configuration information of the resource configured for the first terminal can be provided to the SF.
[0373] The above describes the process in which the SF confirms the sensing terminal and then confirms whether the first terminal allows to participate in the sensing service from the wireless access network device. It is worth noting that the above steps 1004a-1007a can be replaced by: the wireless access network device determines the first terminal participating in the sensing task. The wireless access network device determines whether the first terminal allows to participate in the sensing task according to the awareness authorization information of the first terminal. If the awareness authorization information of the first terminal indicates that the first terminal allows to participate in the sensing task, the wireless access network device determines to perform the sensing measurement by the first terminal.
[0374] The following will describe a process in which the wireless access network device directly selects a sensing terminal according to the sensing authorization information of the terminal.
[0375] Step 1004b: The wireless access network device determines whether the first terminal is allowed to participate in the sensing task according to the sensing authorization information of the first terminal.
[0376] As an example, in the case where the wireless access network device determines that the sensing task needs to be performed, the wireless access network device can perform step 1004b.
[0377] For example, the wireless access network device can determine that the sensing task needs to be performed according to its own needs or an indication of the SF network element. For example, the wireless access network device can determine that the sensing task needs to be performed based on an indication of the SF, or the wireless access network device is configured with a condition for performing the sensing task, and when the wireless access network device determines that the condition for performing the sensing task is met, it is determined that the sensing task needs to be performed.
[0378] In a possible implementation of the present application, before step 1004b, the method provided by the embodiments of the present application can further include: the SF sends a first sensing service request to the wireless access network device, the first sensing service request being used for the wireless access network device to select a terminal to participate in the sensing task.
[0379] Correspondingly, for the wireless access network device, it can perform step 1004b according to the first sensing service request. Specifically, the wireless access network device selects a terminal as the first terminal from one or more terminals according to the first sensing service request. Then the wireless access network device determines whether the first terminal is allowed to participate in the sensing task according to the sensing authorization information of the first terminal. If the sensing authorization information of the first terminal indicates that it is allowed to participate in the sensing task, the wireless access network device selects the first terminal to participate in the sensing task, i.e., the first terminal as a sensing terminal. If the sensing authorization information of the first terminal indicates that the first terminal is not allowed to participate in the sensing task, the wireless access network device will not select the first terminal to participate in the sensing task, i.e., the first terminal will not be a sensing terminal. For example, the wireless access network device can select a terminal as the first terminal from one or more terminals based on the location information of the one or more terminals. As to how the wireless access network device selects the first terminal based on the location information of the terminal, reference can be made to the description in the prior art, which is not limited by the embodiments of the present application.
[0380] As an example, the first sensing service request described above can further include area information, so as to facilitate the wireless access network device to select the first terminal from the area indicated by the SF based on the indication of the SF.
[0381] In another possible implementation of the present application, before step 1004b, the method provided by the embodiments of the present application can further include: the SF sending a second sensing service request to the radio access network device, the second sensing service request comprising the identity of one or more terminals, the one or more terminals comprising the first terminal. The second sensing service request is used for the radio access network device to confirm the selection of a terminal from the one or more terminals to participate in the sensing task.
[0382] Correspondingly, for the radio access network device, it can perform step 1004b according to the second sensing service request. Specifically, the radio access network device, according to the second sensing service request, takes the terminal in the one or more terminals whose sensing authorization information indicates that it is allowed to participate in the sensing service as the first terminal.
[0383] Optionally, in the scenario where the SF sends the second sensing service request to the radio access network device, if the second sensing service request carries the identity of the first terminal, if the radio access network device determines, according to the sensing authorization information of the first terminal, that the first terminal is not allowed to participate in the sensing task, the radio access network device can send a response message to the SF to indicate that the first terminal is not allowed to participate in the sensing task, which facilitates the SF to determine that the first terminal is not allowed to participate in the sensing task, so as to trigger the SF to perform subsequent steps, such as the process of reselecting a terminal. If the radio access network device determines, according to the sensing authorization information of the first terminal, that the first terminal is allowed to participate in the sensing task, the radio access network device can send a response message to the SF to indicate that the first terminal is allowed to participate in the sensing task, and optionally, the radio access network device can further perform step 1005b.
[0384] On the one hand, if the second sensing service request carries the identities of multiple terminals, if the radio access network device determines, according to the sensing authorization information of the multiple terminals, that none of the multiple terminals is allowed to participate in the sensing task, the radio access network device can send a response message to the SF, the response message being used to indicate that the sensing task is successfully established or fails. Optionally, the response message further comprises indication information used to indicate the reason for the failure of the sensing task, such as the indication that none of the multiple terminals is allowed to participate in the sensing task.
[0385] If the second sensing service request carries the identities of multiple terminals, the radio access network device can select any one of the multiple terminals as the first terminal according to the sensing authorization information of the multiple terminals. Alternatively, the radio access network device can first select one of the multiple terminals, and then determine whether the terminal is allowed to participate in the sensing task based on the sensing authorization information of the terminal. If the terminal is not allowed to participate in the sensing task, another terminal is selected. If the sensing authorization information of the another terminal indicates that the another terminal is allowed to participate in the sensing task, the radio access network device selects the another terminal as the first terminal allowed to participate in the sensing task. Optionally, the radio access network device can also send a response message to the SF, where the response message carries the identity of the first terminal, so as to facilitate the SF to determine the identity of the terminal selected by the radio access network device to participate in the sensing service.
[0386] In another possible implementation manner of the present application, before step 1004b, the method provided by the embodiments of the present application can further include: the SF sends a third sensing service request to the radio access network device, where the third sensing service request carries the identity of the first terminal. The third sensing service request is used for the radio access network device to configure the sensing-related resource for the first terminal. In this scenario, the radio access network device can obtain the sensing authorization information of the first terminal, and then determine whether the first terminal is allowed to participate in the sensing task based on the sensing authorization information of the first terminal. If the first terminal is allowed to participate in the sensing task, the radio access network device performs step 1005b described below. If the first terminal is not allowed to participate in the sensing task, the radio access network device can also send a response message to the SF, where the response message is used for the SF to determine that the sensing service is not successfully established. For example, the response message can carry an indication information, which is used to indicate the reason why the sensing service is not successfully established. For example, the reason why the sensing service is not successfully established is that the first terminal is not allowed to participate in the sensing task.
[0387] Optionally, if the first terminal is allowed to participate in the sensing task, the radio access network device can also send a response message to the SF, where the response message is used to determine that the sensing service is successfully established.
[0388] The specific implementation manner of step 1004b is described in the above embodiments, and will not be described here.
[0389] Step 1005b: The radio access network device configures the sensing resource for the first terminal.
[0390] It can be understood that the above steps 1004a-1008a and steps 1004b-1005b are two parallel cases. The steps 1004a-1008a are that the SF first confirms the first terminal participating in the sensing task, and then confirms whether the first terminal is allowed to participate in the sensing task from the node (i.e., the radio access network device) storing the sensing authorization information of the first terminal. The steps 1004b-1005b are the process of the node (i.e., the radio access network device) storing the sensing authorization information of the first terminal regarding the terminal allowed to participate in the sensing task as a sensing terminal according to the sensing authorization information of the first terminal.
[0391] It can be understood that in the above scheme, when the radio access network device or the SF determines that a terminal is allowed to participate in the sensing task, the radio access network device or the SF can configure the terminal to perform the sensing measurement process. For details, refer to the description in the prior art, which will not be repeated here.
[0392] In the above scheme, before selecting a terminal to participate in the sensing task or after selecting the first terminal to participate in the sensing task, the radio access network device determines whether the first terminal is authorized / allowed to participate in the sensing task according to the sensing authorization information of the first terminal. If the terminal is authorized / allowed to participate in the sensing task, subsequent sensing-related processes will be performed, so that the use of the terminal to participate in the sensing task does not infringe the rights of the terminal and ensures the normal operation of the sensing work. If the terminal is not authorized / allowed to participate in the sensing task, the terminal will not be selected to participate in the task, avoiding the sensing mode related to the terminal from not working normally. Therefore, the scheme of the present application can enable the sensing mode related to the terminal to work normally.
[0393] As shown in FIG. 11, FIG. 11 is a specific flowchart of another sensing communication method provided by an embodiment of the present application. The difference between the method shown in FIG. 11 and the method shown in embodiment 10 is that the sensing authorization information of the first terminal is stored in the UDM in the embodiment shown in FIG. 11, instead of being stored in the radio access network device in embodiment 10. Specifically, the method comprises:
[0394] In step 1101, the terminal sends the sensing authorization information of the terminal. Correspondingly, the sensing authentication network element receives the sensing authorization information of the terminal from the terminal.
[0395] The specific implementation of step 1101 can refer to the description of step 1001, which will not be repeated here.
[0396] In step 1102, the Saf sends the sensing authorization information of the terminal. Correspondingly, the UDM receives the sensing authorization information of the terminal.
[0397] As an example, the Saf can send a second message carrying the sensing authorization information of the terminal to the UDM.
[0398] At step 1103, the UDM stores the sensing authorization information of the terminal.
[0399] At step 1104a, the SF determines a first terminal participating in the sensing task.
[0400] The specific implementation of step 1104a can refer to the specific implementation of step 1004a described above, which will not be repeated here.
[0401] As another example, optionally, before step 1104a, the SF can further include: sending a request message to the radio access network device, the request message being used to instruct the radio access network device to report to the SF the terminal that can participate in the sensing task. Then the radio access network device determines the identity of one or more terminals that can participate in the sensing task based on the request message (it can be understood that the radio access network device does not know whether the determined one or more terminals are allowed to participate in the sensing task at this time). The radio access network device provides the SF with the information of the terminal, which can be the identity of the terminal or the location information of the one or more terminals. In this scenario, step 1004a can be implemented by the following manner: the SF selects a terminal from the information of one or more terminals reported by the radio access network device as the first terminal participating in the sensing task, and then the SF performs step 1005a.
[0402] As another example, optionally, before step 1004a, the SF can further include: sending a request message to the radio access network device, the request message being used to trigger the radio access network device to report the information of one or more terminals allowed to participate in the sensing task. Then the radio access network device obtains the information of one or more terminals allowed to participate in the sensing task from the UDM or obtains the sensing authorization information of the one or more terminals by performing steps 1104b-1006b based on the request message. Then the radio access network device provides the SF with the information of the one or more terminals or the sensing authorization information of the one or more terminals, and at this time the information of the one or more terminals refers to the information of the terminal allowed to participate in the sensing task, which can be the identity of the terminal or the location information of the one or more terminals. In this scenario, step 1004a can be implemented by the following manner: the SF selects a terminal from the information of one or more terminals reported by the radio access network device as the first terminal participating in the sensing task, and then the radio access network device performs step 1008a, or the SF selects a terminal allowed to participate in the sensing task from the sensing authorization information of one or more terminals reported by the radio access network device as the first terminal. In this scenario, steps 1105a-1107a can be omitted.
[0403] Step 1105a, the SF sends a first request message to the UDM. Correspondingly, the UDM receives the first request message from the SF.
[0404] The first request message is used to request the UDM to confirm whether the first terminal is allowed / authorized to participate in the perception task. For example, the first request message includes the identification information of the first terminal.
[0405] For example, the first request message includes indication information used to request the UDM to confirm whether the first terminal is allowed / authorized to participate in the perception task. For example, the first request message includes the identification information of the first terminal.
[0406] Step 1106a, the UDM sends a response message to the SF, and correspondingly, the SF receives the response message from the UDM.
[0407] The response message is used for the SF to determine whether the first terminal is allowed / authorized to participate in the perception task or is not allowed / unauthorized to participate in the perception task.
[0408] For example, the response message can include first information. For example, the first information can be the judgment result of whether the first terminal is allowed / authorized to participate in the perception task. For example, allowed to participate or not allowed to participate. Or the first information can include the perception authorization information of the first terminal, so as to facilitate the SF to determine whether the terminal is allowed to participate in the perception task according to the perception authorization information of the terminal.
[0409] Step 1107a, the SF sends a notification of confirming the authorization of the terminal to participate in the perception task to the radio access network device, and correspondingly, the radio access network device receives the notification of confirming the authorization of the terminal to participate in the perception task from the SF.
[0410] Through the notification from the SF, the radio access network device can confirm that the terminal is allowed to participate in the perception task, so as to perform the following step 1108a.
[0411] It can be understood that if the SF determines in step 1106a that the first terminal is allowed to participate in the perception task, step 1107a is performed.
[0412] Step 1108a, the radio access network device configures the first terminal with perception-related resources.
[0413] Optionally, after the radio access network device configures the first terminal with the perception-related resources, the radio access network device can further send configuration information of the perception-related resources configured for the first terminal to the SF.
[0414] It is worth mentioning that, in the above solution, the SF determines the sensing terminal first, and then confirms whether the sensing terminal is allowed to participate in the sensing task from the UDM. In actual process, if the step 1104a is omitted, the first request message sent by the SF to the UDM can include an area information or information of one or more terminals. The area information can be an area served by the SF, so that the first request message can be used to request the UDM to provide sensing authorization information of one or more terminals in the area. If the first request message includes information of one or more terminals, the first request message can be used to request the UDM to provide sensing authorization information of the one or more terminals. In this case, the UDM can send sensing authorization information of part or all of the one or more terminals to the SF, and then the SF selects one or more terminals allowed to participate in the sensing task from the part or all of the terminals according to the sensing authorization information.
[0415] The above solution describes the process that, after the SF determines the sensing terminal, the SF determines whether the sensing terminal is allowed to participate in the sensing task from the UDM. The following describes, from the perspective of the radio access network device, how the radio access network device determines whether the sensing terminal is allowed to participate in the sensing task after the radio access network device determines the sensing terminal.
[0416] As an example, as shown in FIG. 11, the method provided by the embodiment of the present application can further include, after the step 1102:
[0417] The step 1104b includes that the radio access network device determines the first terminal participating in the sensing task.
[0418] In a possible implementation manner of the present application, on one hand, the radio access network device can determine the first terminal participating in the sensing task from the one or more terminals based on sensing demand of the radio access network device.
[0419] In a possible implementation manner of the present application, before the step 1104b, the method provided by the embodiment of the present application can further include that the SF sends a first sensing service request to the radio access network device, and the first sensing service request is used for the radio access network device to select the terminal to participate in the sensing task.
[0420] Correspondingly, for the radio access network device, the step 1104b can be performed according to the first sensing service request.
[0421] In another possible implementation of the present application, before step 1104b, the method provided by the embodiments of the present application can further include: the SF sending a second sensing service request to the radio access network device, the second sensing service request including the identity of one or more terminals, the one or more terminals including the first terminal. The second sensing service request is used to request the radio access network device to select a terminal from the one or more terminals to participate in the sensing task.
[0422] Correspondingly, for the radio access network device, it can perform step 1104b according to the second sensing service request. Specifically, the radio access network device selects the first terminal from the one or more terminals according to the location information of the one or more terminals according to the second sensing service request.
[0423] Optionally, in the scenario where the SF sends the second sensing service request to the radio access network device, if the identity of the first terminal is carried in the second sensing service request, the radio access network device determines the first terminal according to the identity of the first terminal. If the identities of multiple terminals are carried in the second sensing service request, the radio access network device selects one terminal from the multiple terminals as the first terminal according to the identities of the multiple terminals.
[0424] In a possible implementation of the present application, before step 1104b, the method provided by the embodiments of the present application can further include: the SF sending a third sensing service request to the radio access network device, the third sensing service request including the identity of the terminal. For example, the third sensing service request is used to request the radio access network device to allocate sensing-related resources for the terminal associated with the identity of the terminal. In this scenario, the radio access network device can take the terminal identified by the identity of the terminal carried in the third sensing service request as the first terminal. Then the radio access network device can perform steps 1105b-1106b described below to determine whether the first terminal is allowed to be authorized to participate in the sensing service. If the first terminal is allowed to participate in the sensing service, the radio access network device performs step 1107b. If the first terminal is not allowed to be authorized to participate in the sensing service, the radio access network device does not perform step 1107b. Optionally, if the first terminal is not allowed to be authorized to participate in the sensing service, the radio access network device can also send a response message to the SF to indicate that the sensing service is not successfully established. Optionally, the response message can also include indication information indicating the reason for the unsuccessful establishment of the sensing service. For example, the reason for the unsuccessful establishment of the sensing service is that the first terminal is not allowed to participate in the sensing task.
[0425] Step 1105b, the radio access network device sends a first request message to the UDM. Correspondingly, the UDM receives the first request message from the radio access network device.
[0426] The first request message is used to request the UDM to confirm whether the first terminal is allowed to participate in the sensing task.
[0427] At step 1106b, the UDM sends a response message to the wireless access network device. Correspondingly, the wireless access network device receives the response message from the UDM.
[0428] The response message is used for the wireless access network device to determine whether the first terminal is allowed / authorized to participate in the perception task or is not allowed / unauthorized to participate in the perception task.
[0429] For example, the response message can include first information. For example, the first information can be a result of determining whether the first terminal is allowed / authorized to participate in the perception task. For example, the first terminal is allowed to participate or is not allowed to participate. Or the first information can include perception authorization information of the first terminal, so as to facilitate the wireless access network device to determine whether the first terminal is allowed / authorized to participate in the perception task according to the perception authorization information of the first terminal.
[0430] At step 1107b, the wireless access network device configures perception resources for the first terminal.
[0431] It can be understood that if the wireless access network device determines that the first terminal is allowed / authorized to participate in the perception task at step 1106b, step 1107b is executed, otherwise step 1107b is omitted.
[0432] Optionally, if the SF sends a request message to the wireless access network device to request the wireless access network device to determine a terminal allowed to participate in the perception task, if the wireless access network device determines that it is unable to select a terminal allowed to participate in the perception task through the above process, the wireless access network device can send information to the SF to indicate that there is no terminal in the wireless access network device to perform perception.
[0433] It is worth noting that in the above scheme, the wireless access network device first determines the perception terminal, and then confirms whether the perception terminal is allowed to participate in the perception task from the UDM. In actual process, if step 1104b is omitted, the first request message sent by the wireless access network device to the UDM can include a region information or information of one or more terminals. The region information can be a region served by the wireless access network device, so that the first request message can be used to request the UDM to provide perception authorization information of one or more terminals in the region. If the first request message includes information of one or more terminals, the first request message can be used to request the UDM to provide perception authorization information of one or more terminals. In this case, the UDM can send perception authorization information of part or all of the one or more terminals to the wireless access network device, and then the wireless access network device selects one or more terminals allowed to participate in the perception task from the part or all of the one or more terminals as the first terminal according to the perception authorization information of the part or all of the one or more terminals.
[0434] As shown in FIG. 12, FIG. 12 is a specific flowchart of another method of sensing communication provided by the embodiment of the present application. The difference between the method shown in FIG. 12 and the method shown in the embodiment 10 is that, in the embodiment 10, the sensing authorization information of the first terminal is stored in the radio access network device, while in the embodiment shown in FIG. 12, the sensing authorization information of the first terminal is stored in the SF. Specifically, the method comprises the following steps.
[0435] In step 1201, the terminal sends the sensing authorization information of the terminal. Correspondingly, the sensing authentication network element receives the sensing authorization information of the terminal from the terminal.
[0436] In step 1202, the sensing authentication network element sends the sensing authorization information of the terminal. Correspondingly, the SF receives the sensing authorization information of the terminal.
[0437] For example, the sensing authentication network element can actively send the sensing authorization information of the terminal to the SF. The sensing authentication network element can also send the sensing authorization information of the terminal to the terminal based on the request of the SF.
[0438] For example, the sensing authentication network element can send the sensing authorization information of the terminal to the SF through the UDM. Alternatively, the sensing authentication network element can also directly send the sensing authorization information of the terminal to the SF, which is not limited in the embodiment of the present application.
[0439] In step 1203, the SF stores the sensing authorization information of the terminal.
[0440] In step 1204a, the SF determines the sensing terminal according to the sensing authorization information of the first terminal.
[0441] For example, in a possible implementation manner of the present application, the SF can select a terminal as the first terminal from one or more terminals according to the location information of any terminal, and determine whether the first terminal is allowed / authorized to participate in the sensing task according to the sensing authorization information of the selected first terminal. If the first terminal is allowed / authorized to participate in the sensing task, the SF determines that the first terminal is the sensing terminal. Alternatively, the SF selects a terminal allowed to participate in the sensing task as the first terminal from one or more terminals according to the sensing authorization information of any terminal.
[0442] Alternatively, in a possible implementation manner of the present application, before step 1204a, the method provided by the embodiment of the present application can further comprise the following steps: the SF sends a sensing service request to the radio access network device to request the radio access network device to report the identity of one or more terminals, and then the SF selects a terminal from the identity of one or more terminals reported by the radio access network device, and determines whether the terminal is allowed to participate in the sensing task according to the sensing authorization information of the terminal.
[0443] The implementation of step 1204a can refer to the description in the above embodiments, which will not be repeated here. If the SF determines that the first terminal is allowed to participate in the sensing task through the sensing authorization information of the first terminal, the following step 1206a is performed.
[0444] In step 1205a, the SF sends a fourth message to the radio access network device. Correspondingly, the radio access network device receives the fourth message from the SF.
[0445] The fourth message is used for the radio access network device to determine to configure sensing resources for the first terminal, or instruct the radio access network device that the first terminal is allowed / authorized to participate in the sensing task.
[0446] In step 1206a, the radio access network device configures sensing-related resources for the first terminal in response to the fourth message.
[0447] The above steps 1204a-1206a describe the process of determining the first terminal by the SF according to the sensing authorization information of the first terminal, so that subsequent sensing measurement with the selected first terminal can avoid infringing the rights of the first terminal and the situation that the sensing mode related to the terminal cannot work normally.
[0448] In step 1204b, the radio access network device determines the first terminal participating in the sensing task.
[0449] In step 1205b, the radio access network device sends a first request message to the SF. Correspondingly, the SF receives the first request message from the radio access network device. For example, the first request message includes the identifier of the first terminal determined by the radio access network device. For example, the first request message is used to request the SF to confirm whether the first terminal is allowed / authorized to participate in the sensing task.
[0450] For example, the first request message can include indication information, which is used to indicate the SF to confirm whether the first terminal is allowed / authorized to participate in the sensing task.
[0451] In step 1206b, in response to the first request message, the SF confirms whether the first terminal is allowed / authorized to participate in the sensing task according to the sensing authorization information of the first terminal.
[0452] In step 1207b, the SF sends a sixth message to the radio access network device, and the radio access network device receives the sixth message from the SF.
[0453] For example, the sixth message is used to indicate that the first terminal is allowed / authorized to participate in the sensing task, or is not allowed / authorized to participate in the sensing task.
[0454] For example, the sixth message can comprise an indication information, which can be field 1 indicating that the first terminal is allowed / authorized to participate in the sensing task, or field 2 indicating that the first terminal is not allowed / authorized to participate in the sensing task. Or the indication information can be the sensing authorization information of the first terminal. If the indication information is the sensing authorization information of the first terminal, the access network device confirms whether the first terminal is allowed / authorized to participate in the sensing task according to the sensing authorization information of the first terminal.
[0455] If the wireless access network device confirms that the first terminal is allowed / authorized to participate in the sensing task through step 1207b, the following step 1208 is performed, and if the access network device confirms that the first terminal is not allowed / authorized to participate in the sensing task through step 1207b, the above-mentioned step 1204b is performed to reconfirm the sensing terminal and confirm whether the determined sensing terminal is allowed / authorized from the SF.
[0456] Step 1208, the wireless access network device determines to configure the sensing resource for the first terminal.
[0457] As shown in FIG. 13, FIG. 13 is a flow of how to obtain the location information of the terminal provided by an embodiment of the application, and the method comprises:
[0458] Step 1301, the RAN (SU / CU) sends a second request message to the terminal, and correspondingly, the terminal receives the second request message from the RAN.
[0459] The second request message is used to request to obtain the location information of the terminal. For example, the second request message can comprise an indication information, which is used to request the terminal to provide the location information of the terminal. For example, the second request message can comprise the identification information of the terminal.
[0460] Optionally, as an example, the second request message comprises the accuracy of the required location information, and / or the location information reporting trigger condition / period. For example, the trigger condition can be that the terminal needs to report the location information of the terminal when the location of the terminal moves beyond a threshold value, etc.
[0461] As an example, step 1301 can be implemented in the following way:
[0462] • Way 1: the SU requests the CU to obtain the location information of the terminal, and the CU sends a second request message to the terminal. For example, the second request message can be an RRC message.
[0463] • Way 2: The SU generates a terminal location information obtaining message (similar to a NAS message or an RRC inter node message), which is forwarded to the terminal by the CU. Or in a scenario where the SU and the terminal can communicate, the SU directly sends the terminal location information obtaining message to the terminal.
[0464] Step 1302, the terminal sends information related to the location of the terminal to the RAN. Correspondingly, the RAN receives the information related to the location of the terminal from the terminal.
[0465] For example, the information related to the location of the terminal includes one or more of the following: the location information of the terminal, the attribute (moving / static) of the terminal location information, and the time validity of the location information.
[0466] For example, the time validity of the location information of the terminal is used to indicate the time period for which the location information of the terminal is valid, that is, the location information is meaningful within a certain period of time, and the location information should be discarded or the location information of the terminal is invalid or the terminal location information obtaining process is triggered after a certain period of time.
[0467] For example, step 1302 can be implemented in the following ways:
[0468] Way 1: The terminal sends the location information of the terminal to the DU. The DU sends the location information of the terminal, the attribute (moving / static) of the terminal location information, and the time validity of the location information to the CU. Then the CU sends the location information of the terminal, the attribute (moving / static) of the terminal location information, and the time validity of the location information to the SU.
[0469] It can be understood that after the SU obtains the location information of the terminal, it can determine whether to select this terminal to participate in the perception task or participate in the perception task in which mode according to the location information of the terminal.
[0470] Way 2: Or in a scenario where the SU and the terminal can communicate, the terminal sends the location information of the terminal, the attribute (moving / static) of the terminal location information, and the time validity of the location information to the SU.
[0471] Optionally, after step 1302, it can further include:
[0472] Step 1303, the terminal determines that the reporting trigger condition / period is met, and the terminal can actively report the latest information related to the location of the terminal to the SU.
[0473] For example, the trigger condition is that the location of the terminal is greater than or equal to a threshold value, in other words, during the movement of the terminal, the terminal determines that the location of the terminal is greater than or equal to the threshold value, and then the terminal actively reports the latest information related to the location of the terminal to the SU.
[0474] The threshold value can be configured by the network or predefined by the protocol, which is not limited in the embodiments of the present application.
[0475] For example, the terminal determines that the reporting period is met, and then the terminal actively reports the latest information related to the position of the terminal to the SU.
[0476] It can be understood that if the terminal is moving, although the position of the terminal after moving does not exceed the threshold value, the reporting period is met, and then the terminal can actively report the latest information related to the position of the terminal to the SU.
[0477] It can be understood that the reporting trigger condition / period can be obtained by the terminal through step 901, or can be pre-configured in the terminal, or can be determined by the protocol, which is not limited in the embodiments of the present application.
[0478] Optionally, after step 1303, the method can further include:
[0479] Step 1304, the SU sends the information related to the position of the terminal to the DU. Correspondingly, the DU receives the information related to the position of the terminal.
[0480] For example, the DU can determine whether to select the terminal to participate in the sensing task according to the information related to the position of the terminal. Or, the DU determines the sensing data / result in the terminal receiving mode of the base station.
[0481] As shown in FIG. 14, FIG. 14 is a flow of how to obtain the position information of the terminal provided by the embodiments of the present application, and the method includes:
[0482] Step 1401, the RAN requests the position information of the terminal from the SF.
[0483] For example, step 1001 can be implemented by the following way:
[0484] The SU requests the position information of the terminal from the SF, the SF obtains the position information of the terminal from the LMF, and sends the position information of the terminal to the SU.
[0485] The SU can obtain the position information of the terminal from the SF / LMF through the CU (which can be based on the terminal sensing context management related message sent by the SU to the CU to request the CU to obtain the position information of the terminal).
[0486] Step 1402, the SF obtains the position information of the terminal from the LMF.
[0487] Optionally, the SF can also obtain the time limit corresponding to the position information.
[0488] Step 1403, the SF sends the position information of the terminal, and correspondingly, the SU obtains the position information of the terminal.
[0489] Optionally, the SF can also send the time validity of the terminal location information. Correspondingly, the SU can also obtain the time validity of the terminal location information. For example, the SF sends the terminal location information in the following ways:
[0490] The SF sends the terminal location information to the SU. Or the SF sends the terminal location information to the CU, and then the CU forwards the terminal location information to the SU.
[0491] Optionally, in the case where the SU obtains the terminal location information, or obtains the terminal location information and the time validity corresponding to the terminal location information, the method provided by the embodiments of the present application can further include:
[0492] Step 1404, the SU sends the terminal location information or the terminal location information and the time validity corresponding to the terminal location information to the DU.
[0493] Optionally, the SF can also provide baseline information of initial perception, which can also be called initial perception data, background information of perception target, perception result template, initial point cloud information, etc. for determining perception data or perception result. Specifically, the RAN receives the baseline information of perception, and can determine the perception data (point cloud / spectrum information) or the perception result (whether the perception target exists, the category of the perception target, the trajectory of the perception target, etc.) according to the base station information of perception.
[0494] Through the embodiments shown in FIGS. 13 and 14, the RAN can obtain the terminal location information for performing the perception task.

[0523] For example, the location information of the first terminal further includes attributes of the location information and / or a time limit corresponding to the location information.
[0524] For example, the communication module 1513 is further configured to send the location information of the first terminal to a DU of the radio access network device.
[0525] The processing module 1512 can be a processor or a controller, for example, can be a central processing unit, a general processor, a digital signal processor, an application specific integrated circuit, a field programmable gate array, or other programmable logic devices, transistor logic devices, hardware components, or any combination thereof.
