FIG. 1 is a schematic diagram of an application scenario provided by an embodiment of the present disclosure. As shown in FIG. 1 , this scenario includes: a terminal device 101 , a positioning server (LMF) 102 and a mobility management server (AMF) 103 .

It should be noted that the above-mentioned FIG. 1 is schematic, and the above-mentioned scenario may also include other network devices, such as a wireless repeater device and a wireless backhaul device, etc., which are not shown in FIG. 1 . In the embodiment of the present disclosure, one terminal device 101, the location server (LMF) 102, and the mobility management server (AMF) 103 in the above scenario are all taken as an example, but it is not limited thereto.

Wherein, the above-mentioned terminal device 101 may be a device that provides voice and/or data connectivity to the user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem.

Since the methods and devices have similar problem-solving principles, the implementation of the devices and methods can be referred to each other, and repeated descriptions will not be repeated.

Fig. 2 is a schematic flowchart of a positioning method provided by an embodiment of the present disclosure. As shown in FIG. 2, the execution subject of the positioning method of this embodiment may be the above-mentioned positioning server LMF, and the positioning method may include the following steps:

S201. Receive a positioning request.

In some embodiments, the location request is sent by the AMF to the LMF when receiving a location service for locating the terminal device.

S202. According to the device identifier, acquire network type information of the terminal device corresponding to the device identifier.

Correspondingly, when receiving the positioning request, the LMF obtains the identification carried in the positioning request, determines the terminal device to be located according to the identification, and obtains the network type information of the terminal device.

Among them, the network type information is used to indicate the network type of the network connected to the terminal device. The network type is the terrestrial network TN or the non-terrestrial network NTN. At least one or more of network GEOs.

The embodiment of the present disclosure does not specifically limit the specific method of obtaining network type information. For example, on the one hand, the network type information of the terminal device corresponding to the identifier can be obtained from the terminal device context stored in the LMF according to the identifier; on the other hand In another aspect, the network type information of the terminal device may also be obtained through one or more of the terminal device, the base station accessed by the terminal device, and the AMF.

It should be noted that, the specific solutions of the above-mentioned several solutions for obtaining network type information are shown in subsequent embodiments, and will not be repeated here.

S203. Determine a positioning method for the terminal device according to the network type information, and provide a positioning service according to the positioning method.

In practical applications, the positioning methods for terminal devices in different network types are different. For example, the positioning technology based on the space satellite system is suitable for outdoor open environments, that is, it is more suitable for the positioning of terminal devices connected to non-terrestrial networks, while the positioning technology based on The positioning technology of the terrestrial wireless network is more suitable for complex environments such as indoors, urban canyons, and woodlands, that is, it is more suitable for terminal devices connected to the terrestrial network.

As for the determination of the positioning method according to the network type of the terminal device and the solution for locating the terminal device according to the positioning method, reference may be made to the prior art, which will not be repeated here.

In some embodiments, after the LMF locates the terminal device and obtains the location information of the terminal device, it may send the location information to the terminal device, and/or send the location information to the AMF.

Correspondingly, the AMF may forward the positioning result to the terminal device, and/or, the AMF may provide business services such as registration, paging, handover, and access according to the terminal device.

In the embodiments of the present disclosure, an appropriate positioning service may be provided according to the network type of the network where the terminal device is located, so as to maximize the advantages of each network type, thereby providing more accurate location information of the terminal device. Correspondingly, the AMF can also provide more suitable business services for the terminal equipment according to the location information of the terminal equipment, thereby improving the service quality and user experience.
