Problems solved by technology

Considering that 5G positioning is mainly for industry customers, and some industry customers have high requirements for positioning delay, they need flexible deployment of positioning network elements (such as sinking locally, etc.), the network architecture is limited by AMF, and cannot meet the flexible deployment requirements. As a result, some scenarios cannot meet the positioning delay indicators of industry customers

Abstract

The invention provides a positioning method and a positioning system of a terminal. The method is applied to a positioning management function (LMF), and comprises the following steps: selecting a target positioning mode according to a positioning service request; according to the target positioning mode, interacting with a node B or a terminal to obtain measurement information for positioning calculation; and obtaining a positioning result according to the measurement information. According to the invention, the positioning management function LMF is enhanced and is used for triggering the positioning process, so that the cellular positioning capability can be lowered, flexible deployment is carried out for the industry, and the positioning time delay is shortened.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular, to a terminal positioning method and a positioning system. Background technique [0002] 3GPP has introduced the positioning function since the LTE era. The current NR (New Radio, New Radio) positioning process defined in the standard requires the core network element AMF (Authentication Management Function, authentication management function) for triggering and transparent positioning information. pass. AMF is an access and mobility management network element, which is generally deployed at a higher position in the cellular network. Considering that 5G positioning is mainly for industry customers, and some industry customers have high requirements for positioning delay, it is necessary to flexibly deploy positioning network elements (such as sinking local, etc.), the network architecture is limited by AMF and cannot meet flexible deployment requirements. As a ...
