Problems solved by technology

[0022] Security issues: At present, there is a type of application scenario for positioning services that is industrial applications, such as factories. For security reasons, customers in this vertical industry do not want terminal positioning data to be transmitted outside the factory area, but according to figure 2 The positioning process needs to be sent to the AMF. Usually, the AMF of the core network is deployed in a centralized manner and is deployed at a higher position in the network.
Therefore, the current architecture cannot meet the security requirements of some vertical industry applications

Abstract

The embodiment of the invention provides a positioning method and system. The method comprises the steps that a positioning management function LMF located in an access network receives information sent by network equipment in the access network or sends information to the network equipment. According to the scheme of the invention, the positioning time delay can be saved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a positioning method and system. Background technique [0002] At present, location-based services (LoCationSoltuion, LCS) play an increasingly important role in mobile Internet and industrial Internet applications. In order to enable the application of these LCSs, it is critical to quickly obtain accurate positioning information of terminals. [0003] The architecture of terminal positioning in 5G, such as figure 1 As shown, UE (User Equipment, user equipment or terminal) is connected to the access network through the Uu interface. The access network includes: multiple network devices (such as base station gNB), and the access network is connected to the AMF of the core network through the NG-C interface. (Access Management Function, access management function) connection; AMF is connected with LMF (Location Management Function, location management function) thr...
