A positioning method and device

Abstract

Provided are a positioning method and apparatus. The method comprises: a location management network element receiving a first message from a first network element, wherein the first message comprises an identifier of a terminal, and the first message is used to request the acquisition of location information of the terminal; the location management network element determining that a control plane of the terminal is in a congestion control state; the location management network element determining, according to the first message, priority information of acquiring the location information; the location management network element acquiring the location information of the terminal according to the priority information; and the location management network element sending the location information of the terminal to the first network element. By means of the method, a corresponding method for acquiring location information of a terminal may be determined according to priority information of acquiring the location of the terminal. The location information of the terminal is acquired in a more flexible manner, and terminal and network overheads are reduced.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a positioning method and device. Background technique [0002] With the development of communication technology, the fifth generation (the 5th generation, 5G) communication system network has been applied to the Internet of Things, industrial control and other fields, and external applications need to obtain the location information of the terminal through the 5G network, and according to the location information of the terminal Realize related applications and services, such as active push, item tracking, and precise positioning of equipment in factories based on location information. Therefore, the 5G network needs to enhance the location information of the open terminal to external applications. [0003] The core network of the 5G network manages a large number of terminal devices. Since the positioning service and other types of services occupy a l...

Problems solved by technology

[0003] The core network of the 5G network manages a large number of terminal devices. Since the positioning service and other types of services occupy a large number of control plane connections between the terminal and the network, it will cause a large load on the control plane connection of the network. As a result, the control plane may affect the Some terminals perform congestion control, so that the terminal enters the congestion control state

In this case, how to obtain the location information of the terminal in a more flexible manner has not yet given a corresponding solution
