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.

[0252] In some embodiments, a core network device may be a device including one or more network elements, or may be multiple devices or device groups, each including all or part of the one or more network elements. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0253] 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 provided by 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 provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0254] The following embodiments of the present disclosure may be applied to the communication system 100 shown in Figure 1a, or a portion thereof, but are not limited thereto.

[0256] In some embodiments, the target terminal may receive a ranging or SL positioning service request from the SL positioning client terminal or the target terminal's sidelink positioning protocol (RSPP) application layer via PC 5. The service request includes user information of the SL positioning client terminal, user information of the target terminal, and user information of the SL reference terminal (UE2 / ... / UEn).

[0257] In some embodiments, if necessary, UE1 and UE2-n may communicate via PC 5 to obtain authorization for ranging or SL positioning. Each of UE 2-n verifies whether ranging or SL positioning is permitted, including whether the ranging or SL positioning results can be transmitted to a Location Service (LCS) client or an Application Function (AF), if used.

[0258] In some embodiments, the network does not participate in UE-only operations of ranging or SL positioning, and stipulates that the authorization of UE privacy is based on locally configured privacy verification information to determine whether its location-related information can be opened (or exposed) to the opposite UE.

[0259] In some embodiments, the UE shall authorize the received service request based on locally available information for verification. When a ranging or SL positioning service request is sent to request a ranging or SL positioning result, if the ranging or SL positioning operation is allowed and performed, the ranging or SL positioning service response shall include the result. However, since the authorization for UE privacy needs to be checked before performing the ranging or SL positioning operation, it is possible that the UE may not be allowed to perform the ranging or SL positioning operation due to authorization failure. Therefore, the ranging or SL positioning service response may not include any ranging / SL positioning results. In this case, the UE that sent the ranging or SL positioning service request will be informed of the exact reason for not receiving the result.

[0260] In some embodiments, it is not possible for the terminal that sends the ranging or SL positioning service request to know the exact reason for not receiving the ranging or SL positioning result.

[0519] In order to better understand the embodiments of the present disclosure, some exemplary embodiments are further described below:

[0520] Example 1:

[0521] A communication system is provided assuming that a terminal is locally configured or provisioned with information required by the terminal to perform authorization or privacy verification.

[0522] As shown in FIG7a , an embodiment of the present disclosure relates to a communication method, which includes:

[0523] Step S7201a: On PC5, UE-1 (first terminal) receives a ranging / SL positioning service request from the positioning client UE (second terminal).

[0524] In some embodiments, the ranging / SL positioning service request (second information) includes user information of the SL positioning client UE, user information of the target UE, user information of the SL reference UE (UE-2) and a service identifier, etc.

[0525] Step S7201b: UE-1 receives a ranging / SL positioning service request from the RSPP application layer.

[0526] In some embodiments, the ranging / SL positioning service request includes the user information of the SL reference UE (UE-2), the service identifier, etc.

[0527] Step S7202: Performing authorization or privacy check operation. Upon receiving a service request from the client UE or the RSPP application layer, UE-1 (eg, target UE) performs authorization or privacy check operation.

[0528] In some embodiments, it is verified based on the privacy setting (fourth information) whether UE-1 allows the SL positioning result to be opened to the SL positioning client UE.

[0529] In some embodiments, it is verified whether it is allowed to open the SL positioning measurement data or results to UE-2 according to its privacy settings.

[0530] In some embodiments, if privacy settings are not available in UE-1, then if UE-1 is within network coverage, perform step S7203, or if UE-1 is out of network coverage, proceed to step S7204 (S7204a or S7204b, depending on UE implementation).

[0531] Step S7203: Execute the SL-MO-LR procedure and obtain the check result. If the information required by the UE to perform authorization or privacy verification (privacy settings) is not available on the UE, UE-1 triggers the SL-MO-LR procedure to the core network, requesting authorization / privacy checks on UE-1 and UE-2, and obtaining the check results.

[0532] Step S7204a: If any authorization fails, UE-1 will terminate the subsequent process and respond to the SL positioning client UE with the failure reason (first information).

[0533] In some embodiments, for the UE check in step S7202, the failure reason may be a privacy / authorization check failure, or exposure rejected by UE-1, or exposure to the client UE rejected by UE-1, or exposure to UE-2 rejected by UE-1.

[0534] In some embodiments, for the case of network check in step S7203, the failure reason may be failure of privacy / authorization check, or refusal to be exposed to the client UE, or refusal to be exposed to the client UE by UE-1, or refusal to be exposed to the client UE by UE-2, or refusal to be exposed to the client UE by both UE-1 and UE-2.

[0535] Step S7204b: If the UE check in step S7202 is successful or the network check in step S7203 is successful, UE-1 discovers UE-2, and the UE performs capability exchange.

[0536] Step S7205: UE-1 sends a supplementary RSPP service request (sixth information) to UE-2.

[0537] In some embodiments, the request includes user information of the SL positioning client UE, user information of the target UE (UE-1), a service identifier, etc.

[0538] Step S7206: Upon receiving the service request from UE-1, UE-2 (eg, SL reference UE) performs authorization or privacy check operations.

[0539] In some embodiments, it is verified based on its privacy settings (eighth information) whether it allows the SL positioning results to be opened to the SL positioning client UE.

[0540] In some embodiments, it is verified whether it is allowed to open the SL positioning measurement data or results to UE-1 according to its privacy settings.

[0541] In some embodiments, if the privacy setting is not available in UE-2, proceed to step S7207 (S7207a or S7207b, depending on UE implementation).

[0542] Step S7207a1: If any verification in S7206 fails, UE-2 terminates the subsequent process and responds (seventh information).

[0543] In some embodiments, UE-2 aborts subsequent procedures and responds to UE-1 with a failure reason.

[0544] In some embodiments, the failure reason may be a privacy / authorization check failure, or exposure denied by UE-2, or exposure denied by UE-2 to the client UE, or exposure denied by UE-2 to UE-1.

[0545] Step S7207a2: If any verification in S7206 fails, UE-2 terminates the subsequent process and responds (first information).

[0546] In some embodiments, if UE-1 receives a response with a failure cause from UE-2, UE-1 shall abort subsequent procedures and respond to the SL positioning client UE with a failure cause.

[0547] In some embodiments, the failure reason may be a privacy / authorization check failure, or exposure denied by UE-2, or exposure denied by UE-2 to the client UE, or exposure denied by UE-2 to UE-1.

[0548] Step S7207b: If any verification in S7206 succeeds, UE-1 and UE-2 perform SL measurement, data transmission and / or result calculation.

[0549] Step S7208: UE-2 responds to UE-1 with the SL positioning measurement, or if the result calculation is performed by UE-2, responds to UE-1 with the SL positioning result.

[0550] Step S7209: Result calculation: In the case where UE-1 calculates the SL positioning result, UE-1 calculates the result based on the SL positioning measurement received in step S7207b.

[0551] Step S7210a: The ranging / SL positioning result is transmitted to the SL positioning client UE in the ranging / SL positioning service response.

[0552] Step S7210b: The ranging / SL positioning result is transmitted to the RSPP application layer.
