In addition, a combination of multiple systems (for example, a combination of LTE or LTE-A with 5G, etc.) may also be applied.

可选的，在本公开的一个实施例之中，测距服务是指通过直接通信连接确定两个终端之间的距离和 /或一个终端与另一个终端的方向。侧链(Sindlink，SL)定位服务使终端能够使用PC5来获得绝对位置、相对位置或测距信息。测距/SL定位服务可以应用于各种垂直领域，如消费者、智能家居、智能城市、智能交通、智能零售和工业4.0。Optionally, in one embodiment of the present disclosure, the ranging service refers to determining the distance and /or the direction of one terminal to another. Sidelink (SL) positioning service enables terminals to use PC5 to obtain absolute position, relative position or ranging information. Ranging/SL positioning services can be applied to various vertical fields such as consumer, smart home, smart city, smart transportation, smart retail and Industry 4.0.

可选的，在本公开的一个实施例之中，例如应用层ID在两个测距/SL定位终端之间传输，并在测距/SL位置请求中提供给第五代移动通信技术核心网(5th Generation Mobile Communication Technology Core，5GC)，其可以是GPSI或测距应用提供的终端标识。应用层ID需要映射到SUPI或GPSI，这是5GC内部使用的唯一标识符。基于映射的SUPI或GPSI，可以选择相应的5GC网络功能(Network Function，NF)，或者5GC NF(即LMF、AMF)能够识别所涉及的UE以执行测距/SL定位过程。Optionally, in one embodiment of the present disclosure, for example, an application layer ID is transmitted between two ranging/SL positioning terminals and provided to the fifth generation mobile communication technology core network (5th Generation Mobile Communication Technology Core, 5GC) in the ranging/SL position request, which can be a terminal identifier provided by GPSI or a ranging application. The application layer ID needs to be mapped to SUPI or GPSI, which is a unique identifier used internally in 5GC. Based on the mapped SUPI or GPSI, the corresponding 5GC network function (NF) can be selected, or the 5GC NF (i.e., LMF, AMF) can identify the UE involved to perform the ranging/SL positioning process.

然而，如何将应用层ID映射到SUPI或GPSI尚不清楚，即没有应用层ID到SUPI或GPSI的映射机制。如果网络设备无法将应用层ID映射到SUPI或GPSI，则5GC NF(例如AMF、LMF)将无法识别所涉及的终端，从而GMLC无法检查授权，并且无法选择相应的LMF来执行测距/SL定位测量过程。However, it is not clear how to map the application layer ID to SUPI or GPSI, that is, there is no mapping mechanism from application layer ID to SUPI or GPSI. If the network equipment cannot map the application layer ID to SUPI or GPSI, the 5GC NF (such as AMF, LMF) will not be able to identify the terminal involved, so that the GMLC cannot check the authorization and cannot select the corresponding LMF to perform the ranging/SL positioning measurement process.

在SL-移动终端定位请求(Mobile Terminate Location Request，MT-LR)过程中，5GC NF/AF可以发送测距/SL请求，该请求包括所涉及的终端的应用层ID。然而，所涉及的UE可能在不同的PLMN中注册(即UE1属于PLMN1，UE2属于PLMN2)。但是，服务网络中UE1的NF无法通过使用应用层ID2找到UE2的本地网络。因此，LMF不能基于终端的应用层ID跨PLMN来获得终端的SUPI或GPSI，并且不能提供测距/SL定位服务，使得定位的准确性较差。During the SL-Mobile Terminate Location Request (MT-LR) process, the 5GC NF/AF can send a ranging/SL request, which includes the application layer ID of the terminal involved. However, the UEs involved may be registered in different 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 ID2. Therefore, the LMF cannot obtain the SUPI or GPSI of the terminal across PLMNs based on the application layer ID of the terminal, and cannot provide ranging/SL positioning services, resulting in poor positioning accuracy.
