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. A person of ordinary skill in the art 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.

The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or part of the subject, but are not limited thereto. The subjects shown in FIG1 are examples, and the communication system may include all or part of the subjects in FIG1 , or may include other subjects other than FIG1 , and the number and form of each subject are arbitrary, and each subject may be physical or virtual, and the connection relationship between the subjects is an example, and the subjects may be connected or disconnected, and the connection may be in any manner, and may be a direct connection or an indirect connection, and may be a wired connection or a wireless connection.

The embodiments of the present disclosure may be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, the fourth generation mobile communication system (4G), the fifth 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 ... The present invention relates to wireless communication systems such as LTE, Wi-Fi (X), 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) network, Device to Device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Vehicle to Everything (V2X), systems using other communication methods, and next-generation systems expanded based on them. In addition, a combination of multiple systems (for example, a combination of LTE or LTE-A with 5G, etc.) may also be applied.

In one embodiment provided in the present application, the ranging service refers to determining the distance between two UEs and/or the direction of one UE relative to another UE via a PC5 link. The sidelink (SL) positioning service enables the UE to obtain its absolute position, relative position or ranging information using the PC5 communication link. The ranging/SL positioning service can be applied to various vertical fields such as consumers, smart homes, smart cities, smart transportation, smart retail and Industry 4.0.

In one possible embodiment, an application layer ID is transmitted between two ranging/SL positioning UEs and provided to the 5GC in the ranging/SL positioning request, which may be a generic public subscription identifier (GPSI) or a UE identity provided by the ranging application. The application layer ID needs to be mapped to a subscription permanent identifier (SUPI), which is a unique identifier used internally by the 5GC.

Optionally, the corresponding 5GC network function (NF) can be selected based on the mapped SUPI or GPSI, or the 5GC NF (e.g. LMF, AMF) can identify the UE involved to perform ranging/SL positioning procedures.

In one possible embodiment, how to map the application layer ID to GPSI is not clear in the current study. If the network cannot map the application layer ID to SUPI or GPSI, the 5GC NF (such as AMF, LMF) will not be able to identify the UE involved, and thus cannot check the authorization through GMLC, nor can it select the corresponding LMF for ranging/SL positioning measurement procedures.

In the sidelink-mobile original-location request (SL-MT-LR) procedure, the UEs involved may be registered in different Public Land Mobile Networks (PLMNs) (i.e., UE1 belongs to PLMN1 and UE2 belongs to PLMN2). However, the NF of UE1 in the serving network cannot find the local network of UE2 by using the application layer ID 2. Therefore, there is currently a lack of methods for resolving the application layer ID to the corresponding SUPI or GPSI across PLMNs.

If the authorization check of any of the first terminal and the second terminal fails, the second network element may not send the fourth message to the first network element.
