In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0303] In some embodiments, the access network device 102 can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0304] In some embodiments, the first network function 103 is, for example, an Access and Mobility Management Function (AMF).

[0305] In some embodiments, the second network function 104 is, for example, a location management function (LMF), or may be other perception-related network functions, or may be a network function specifically designed for perception services, etc., which is not limited in this disclosure.

[0306] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0307] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0308] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods.

[0309] Radar (radio detection and ranging) is a widely used wireless sensing technology that uses radio waves to determine the distance (range), angle, or instantaneous linear velocity of an object. Other sensing technologies include non-RF sensors already used in other fields, such as time-of-flight cameras, accelerometers, gyroscopes, and lidar.

[0310] Integrated sensing and communication in 3rd Generation Partnership Project (3GPP) systems means that sensing capabilities are provided by the same wireless communication system and infrastructure used for communication. In addition, both UEs and NR RAN nodes can act as both sensing senders and sensing receivers in 3GPP-enabled sensing systems.

[0311] In sensing scenarios, the UE / gNB can unknowingly perceive humans. The UE / gNB can obtain sensitive information about humans (e.g., heart rate) through the sensing process. To avoid being unknowingly perceived, humans should be able to use their UE to detect potential sensing tasks. One possible approach is to have the UE receive broadcast information about sensing tasks. However, there is currently no existing mechanism for broadcasting sensing task information.

[0319] In some embodiments, the first request may be sent by a server associated with the perception task, which is not limited in this disclosure.

[0320] In some embodiments, the second network function 104 may send the perception task information to the first network function 103 via the Namf_Communication_NonUeN2MessageTransfer service.

[0321] In some embodiments, the second network function 104 may also send an identifier of a target device to the first network function, where the target device may be a target access network device or a target terminal, etc., which is not limited in this disclosure.

[0322] In some embodiments, the perception task information may include at least one of the following: a perception task indicator, a perception area, a perception time, a perception direction, a perception key performance indicator KPI, etc., which is not limited in the present disclosure.

[0323] In some embodiments, the perception task indicator is used to indicate the presence or absence of a perception task, which may be implemented in any form and is not limited in this disclosure.

[0324] In some embodiments, terms such as "sensing area" and "sensing area" can be used interchangeably.

[0325] In some embodiments, terms such as "sensing time" and "sensing period of time" may be used interchangeably.

[0326] In some embodiments, terms such as "sensing direction" and "sensing direction" can be used interchangeably.

[0327] In some embodiments, terms such as “sensing key performance indicator”, “sensing KPI”, and “Sensing Key Performance Indicator” may be used interchangeably.

[0337] In some embodiments, the access network device 102 may be any one of the following: an access network device associated with the device identifier sent by the second network function 104 .

[0338] That is, if the second network function 104 sends the identifier of the target device to the first network function 103, for example, the identifier of the target access network device 102, the first network function 103 can directly send the sensing task information to the target access network device 102. Alternatively, if the device identifier sent by the second network function 104 is the identifier of the terminal, the first network function can send the sensing task information to the access network device 102 currently connected to the terminal.

[0339] In some embodiments, the second network function 104 does not send the identifier of the access network device 102 to the first network function 103, and the first network function 103 can determine the target access network device 102 on its own. For example, the first network function 103 can determine the perception sender or perception receiver associated with the second network function 104 as the target access network device 102.

[0340] That is to say, there is an association relationship between the access network device 102 and the second network function 104. After receiving the perception task information sent by the second network function 104, the first network function 103 can determine the target access network device 102 based on the association relationship.

[0341] In some embodiments, the first network function 103 may also determine that all access network devices 102 connected to the first network function 103 are target access network devices 102, thereby sending perception task information to all access network devices 102 connected thereto. This disclosure does not limit this.

[0342] In some embodiments, the device identifier is an identifier for representing the target device, which may be in any form. For example, the device identifier may be the name of the target access network device 102, etc., which is not limited in this disclosure.

[0347] In step S2104 , the access network device 102 determines the sensing task information.

[0348] In some embodiments, after receiving the sensing task information, the access network device 102 may determine information such as the sensing task area information, the sensing task duration, the sensing direction of the sensing task, and the KPI of the sensing task.

[0349] In step S2105 , the access network device 102 sends the sensing task information via broadcast.

[0350] In some embodiments, when the access network device 102 is a perception sender or a perception receiver, the access network device 102 may send the perception task information by broadcasting after determining the perception task information.

[0351] In some embodiments, the first terminal 1011 receives the perception task information broadcast by the access network device 102 .

[0352] In step S2106, the first terminal 1011 determines the sensing task according to the sensing task information in the broadcast information.

[0353] In some embodiments, the broadcast information is broadcast by the access network device 102 .

[0354] In some embodiments, determining a perception task may be determining whether a perception task exists, or determining an area of ​​the perception task, or determining a time period during which the perception task runs, or determining a KPI of the perception task, etc. This disclosure does not limit this.

[0355] Step S2107 : The access network device 102 sends a feedback message to the first network function 103 .

[0360] Step S2108 : The first network function 103 sends a second feedback message to the second network function 104 .

[0361] In some embodiments, the second feedback message is used to indicate that the broadcast of the perception task information has been completed.

[0362] In some embodiments, after receiving the first feedback message sent by the access network device 102, the first network function 103 can obtain the routing identifier of the second network function 104 from the first feedback message, and then the first network function 103 sends a second feedback message to the target second network function 104 through the Namf_Communication_NonUeNInfoNotify service.

[0363] In some embodiments, the second network function 104 receives the second feedback message sent by the first network function 103 .

[0364] The communication method involved in the embodiment of the present disclosure may include at least one of steps S2101 to S2108. For example, steps S2101+S2102 may be implemented as independent embodiments, and step S2103 may be implemented as an independent embodiment, etc., but the present invention is not limited thereto.

[0365] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.

[0366] In the embodiments of the present disclosure, each step can also be implemented independently.

[0367] In this embodiment, after receiving a request to start a perception task, the second network function sends perception task information to the first network function, and then the first network function sends the perception task information to the access network device. Thereafter, the access network device sends the perception task information by broadcasting to assist the first terminal in determining the perception task, thereby realizing a mechanism for broadcasting perception task information and improving the security of the communication system.

[0368] FIG2B is an interactive diagram of a communication method according to an embodiment of the present disclosure.

[0378] In some embodiments, the device identifier is an identifier used to represent the second terminal, which can be in any form. For example, the device identifier can be the name of the second terminal 1012, etc., which is not limited in this disclosure.

[0379] In some embodiments, second network function 104 does not send the identifier of second terminal 1012 to first network function 103, and first network function 103 can determine second terminal 1012 on its own. For example, first network function 103 can determine the second terminal 1012 as the perception sender or perception receiver associated with second network function 104.

[0380] In some embodiments, the second terminal 1012 receives the perception task information sent by the first network function 103 through the access network device 102.

[0750] The following is an exemplary introduction to the above method.

[0751] This disclosure is used to solve the problem of how to implement a mechanism for broadcasting perception task information. The optional implementation solutions are as follows:

[0752] The present disclosure relates to a communication method, in which the first network function is an access and mobility management function (AMF), and the second network function is a location management function (LMF) or a perception network function. The method includes:

[0753] The LMF / perception network function can support the broadcast of network assistance data or perception task information to the target user equipment (UE) through the following procedure. This procedure is not associated with the UE location session. It sends the perception task information to the next generation radio access network (NG-RAN) node through the AMF, and then the access network equipment broadcasts it to the target UE.

[0754] Assuming that the sensing task can be a Gateway Mobile Location Center (GMLC), LMF, or a function developed specifically for the sensing scenario, as shown in FIG9A , FIG9A is a schematic diagram of the interaction of sensing task information broadcast based on access network devices.

[0755] 1. After receiving a perception task, the LMF / perception network function may call the Namf_Communication_NonUeN2MessageTransfer service operation to the AMF to request the transfer of the perception task information to the access network equipment (e.g., the NG-RAN node (gNB or NG-eNB) in the NG-RAN). This service operation may include the perception task information and the target NG-RAN node identity.

[0756] The sensing task information may include sensing area information, sensing duration information, sensing task direction information, etc.

[0757] 2. The AMF forwards the awareness task information to the target access network device indicated in step 1 in the N2 transport message. The AMF may also include a routing identifier for identifying the LMF / aware network function in the N2 transport message.

[0758] 3. The access network device broadcasts the sensing task information.

[0759] 4. The target access network device may return feedback about the broadcast of the sensing task information to the AMF in the sensing task information feedback message. The target access network device may also obtain the routing identifier from the N2 transmission message received by the AMF in step 2.

[0760] 5. The AMF invokes the Namf_Communication_NonUeNInfoNotify service operation to the LMF / perception network function indicated by the routing identifier received in step 4. The service operation includes the perception task information feedback message received in step 4.

[0761] Alternative 1:

[0762] UE can be a sensing sender or a sensing receiver. As shown in FIG9B , FIG9B is a schematic diagram of interaction based on UE sensing task information broadcasting.

[0763] 1. The LMF / perception network function calls the Namf_Communication_N1N2MessageTransfer service operation to the AMF to request the transmission of perception task information to the UE, where the service operation includes the perception task information.

[0764] 2.AMF forwards the sensing task information to the UE in the DL NAS transport message.

[0765] 3.UE broadcasts sensing task information.

[0766] 4. The UE sends the sensing task information feedback to the AMF via UL NAS transmission message.

[0767] 5.AMF sends a feedback message to the LMF / perception task by calling the Namf_Communication_N1MessageNotify service operation. The service operation includes the perception task information feedback.

[0768] Alternative 2:

[0769] In this solution, once the sensing task is started, the broadcast of the sensing task information can be triggered by the access network device itself. As shown in Figure 9C, Figure 9C is a schematic diagram of the interaction of broadcasting the sensing task information based on local information.

[0770] 1. If the access network device is a sensing sender / receiver, the access network device broadcasts the sensing task information.

[0771] Alternative 3:

[0772] In this solution, once the LMF / perception network function has been selected for the perception task, the broadcast of the perception task information can be triggered by the AMF itself. Figure 9D shows the interaction diagram of the access network device perception task information broadcast considering the LMF / perception task selection.

[0773] 1.AMF performs LMF / perception network function selection.

[0774] 2. After selecting LMF / perception network function to perform the perception task, AMF can transmit messages through N2 to forward the perception task information to the target access network device.

[0775] 3. The access network device broadcasts the sensing task information.

[0776] 4. The target access network device may return feedback on the broadcast of the perception task information to the AMF in the perception task information feedback message.

[0777] Alternative 4:

[0778] In this solution, once the LMF / perception network function has been selected for the perception task, the broadcast of the perception task information can be triggered by the AMF itself. As shown in Figure 9E, Figure 9E shows the interaction diagram of UE-based perception task information broadcast considering LMF / perception function selection.

[0779] 1.AMF performs LMF / perception network function selection.

[0780] 2. After selecting LMF / perception network function to perform the perception task, AMF can forward the perception task information to UE in the DL NAS transmission message.

[0781] 3.UE broadcasts sensing task information.

[0782] 4. The UE sends the sensing task information feedback to the AMF via UL NAS transmission message.
