In one embodiment, the authorization of the SL positioning client terminal needs to be performed at different levels, where:

The second level of authorization is used to protect UE privacy. This is because even if the SL positioning client UE is authorized to request ranging or SL positioning services, it does not mean that the ranging or SL positioning results of any pair of terminals can always be opened to the SL positioning client terminal. For example, the SL positioning client terminal may be allowed to request the ranging results between UE1 and UE2, but the ranging results between UE3 and UE4 may not be allowed. Without further checking the authorization information of the terminals involved, there is still a risk that the ranging results between specific terminals may be open to unauthorized SL positioning client terminals. Therefore, it is necessary to further authorize the SL positioning client terminal whether it is allowed to obtain the ranging results of the terminals involved.

In one embodiment, the SL positioning client terminal can obtain the ranging or SL positioning results between the two terminals through the PC5 interface (if the SL positioning client terminal is close enough to one of the terminals to establish a PC5 link) or through the network (if the SL positioning client terminal is too far away from either terminal to establish a PC5 link).

In order to better understand the embodiments of the present disclosure, the technical solution of the present disclosure is further described below through two exemplary embodiments:

For disclosure of ranging or sidelink positioning services to the client terminal via the network, the client UE shall first send an enhanced MO-LR request to the AMF, which invokes a ranging or SL positioning request to the GMLC. The GMLC reuses the procedure described in the conclusion of clause 8.7 of 3GPP TR 23.700-86 [1] (similar to the request from the application server) and sends the ranging or SL positioning result to the AMF, which returns the result to the SL positioned client terminal.

Based on the above process, the GMLC that receives the ranging or SL positioning request (including the client terminal information and the information of the terminal to be measured) should initiate an authorization check of the SL positioning client terminal to the ranging or SL positioning server, and the ranging or SL positioning server has application-level information for authorization.

Example 1:

As shown in FIG. 11 , this embodiment provides a method for authorizing a positioning service, wherein the method includes:

Step 111: The client terminal triggers a ranging or SL positioning service request and establishes a signaling connection with the AMF.

Step 112: The client terminal sends a MO-LR request message included in a UL NAS transmission message. The MO-LR request message includes at least information about the client terminal and the UE to be measured (UE1/UE2). Among them, MO-LR is a terminal originated location request (MO-LR, Mobile Originated Location Request).

Optionally, in some implementation modes of the present application, the information of the client terminal and the information of the UE pair to be measured (such as UE1 and/or UE2) may be carried in other messages, and is not limited to the above MO-LR request message.

Optionally, in some implementation modes of the present application, the information of the UE pair to be measured (such as UE1 and/or UE2) may be an identifier of a ranging service or a positioning service between the UE pair, and is not limited to the identifier of the UE itself.

Step 113: AMF sends ranging or SL positioning request information to GMLC, and the SL positioning request information also includes information of the client terminal and UE1 and/or UE2.

Similar to step 112, optionally, in some embodiments of the present application, the SL positioning request information may include an identifier of a ranging service or a positioning service between the UE pair.

Step 114: GMLC sends authorization request information to the ranging or SL positioning server, wherein the authorization request information includes information of the client terminal and UE1 and/or UE2.

Step 115: The ranging/SL positioning server checks, for example, the application protocol to see whether the client terminal is allowed to obtain the ranging result of UE1/UE2.

Optionally, in some implementations of the present application, steps 111 to 114 are optional steps, and the second network device may determine, based on a request from a client terminal or other network device (the other network device may be a network device not shown in FIG. 11), the ranging/positioning results of one or more UE pairs that the client terminal is authorized to obtain. The UEs include UE1 and UE2, and the ranging/positioning results include ranging/positioning results between UE1 and/or UE2.

Step 116: The ranging/SL positioning server returns the authorization result to the GMLC.

Step 117a: If the authorization is successful, the GMLC further checks the UE privacy profile in the subscription information of UE1 and UE2. Whether UE1 and UE2 are allowed to disclose their location-related information.

Optionally, in some embodiments of the present application: step 117a can refer to solution #3 in 3GPP TR 33.893 [2].

Step 117b: If the authorization fails, the GMLC returns a ranging/SL positioning response message with the reason for failure to the AMF (corresponding to the first SL positioning response message in the present disclosure).

Optionally, step 117a and step 117b are optional steps.

Step 118. After step 117a, the rest of the ranging/SL positioning process is performed between GMLC and AMF.

Optionally, in some embodiments of the present application, under the instruction of network devices such as GMLC and/or AMF, UE1 and UE2 perform relative ranging and/or positioning.

Step 119: GMLC sends the ranging results of UE1 and/or UE2 to AMF.

Optionally, in some implementations of the present application, UE1 and/or UE2 sends the ranging/positioning result to AMF or GMLC. Step 120: When AMF receives the ranging result of UE1 and/or UE2 from GMLC, it sends the result to the client terminal.

In one embodiment, authorization of the client UE may be performed after the GMLC checks the location privacy profiles of UE1 and UE2. If the location privacy check of UE1 and/or UE2 is successful, the GMLC then initiates an authorization check of the client mid- to high-end with the ranging or SL positioning server. Otherwise, the GMLC aborts the authorization check of the client UE and returns a ranging/SL positioning response with a failure reason to the AMF.

Optionally, in some embodiments of the present application, when UE1 and/or UE2 can directly discover the client terminal, the ranging result can be sent to the client UE;

Optionally, in some embodiments of the present application, when UE1 and/or UE2 can indirectly discover the client terminal, the ranging result can be sent to the client UE via the relay UE;

Example 2:

As shown in FIG. 12 , this embodiment provides a method for authorizing a positioning service, wherein the method includes:

Step 121: The client terminal triggers a ranging or SL positioning service request and establishes a signaling connection with the AMF.

Step 122: The client terminal sends a MO-LR request message included in a UL NAS transmission message. The MO-LR request message includes at least information of the client terminal and the UE to be measured (UE1/UE2). Among them, MO-LR is a terminal originated location request (MO-LR, Mobile Originated Location Request).

Step 123: AMF sends ranging or SL positioning request information to GMLC, and the SL positioning request information also includes information of the client terminal and UE1 and/or UE2.

Step 124: Check whether UE1 and UE2 allow to disclose their location-related information by comparing the UE privacy profiles in the subscription information of UE1 and UE2.

Step 125a: If the location-related information is allowed to be disclosed, the GMLC sends an authorization request message to the ranging or SL positioning server, wherein the authorization request message contains information of the client terminal and UE1 and/or UE2.

Step 125b: If the location-related information is not allowed to be opened, the GMLC returns a ranging/SL positioning response message with the failure reason to the AMF.

Step 126: The ranging/SL positioning server checks, for example, the application protocol to see whether the client terminal is allowed to obtain the ranging result of UE1/UE2.

Step 127: The ranging/SL positioning server returns the authorization result to the GMLC.

Step 128: Perform the rest of the ranging/SL positioning process between GMLC and AMF.

Step 129: GMLC sends the ranging results of UE1 and/or UE2 to AMF.

Step 130: When the AMF receives the ranging result of UE1 and/or UE2 from the GMLC, it sends the result to the client terminal.
