Locating methods, locating system and relevant equipment

Abstract

The invention discloses locating methods, a locating system and relevant equipment. The using frequency of terminal equipment and a base station locating platform of a located user is reduced in a locating process, and locating speed and locating accuracy are improved. One of the locating methods comprises that the terminal equipment carries out global position system (GPS) / assisted global position system (AGPS) locating according to sampling frequency in each locating cycle; if at least one piece of GPS position information is acquired successfully, the GPS position information is reported to a locating server; and if the GPS position information is not acquired and movement is judged according to cellular identify (CI) information, first indicating information is reported. Another locating method comprises that the terminal equipment judges whether moving happens according to the CI information in each locating cycle; when a judged result is that moving happens, GPS / AGPS locating is carried out, if the GPS position information is successfully acquired, the GPS position information is reported to the locating server, and if the GPS position information is not acquired, the first indicating information is reported.

Description

technical field [0001] The present invention relates to the technical field of positioning, in particular to a positioning method, system and related equipment. Background technique [0002] A positioning system refers to a system that uses one or more positioning technologies to provide users with their own location information or other people's location information. The positioning system generally includes the terminal equipment of the positioned user and a positioning platform that provides specific positioning methods. In the prior art, commonly used positioning technologies include: GPS (Global Positioning System, Global Positioning System) / AGPS (Assisted Global Positioning System, Assisted Global Positioning System) positioning technology, base station positioning technology, and the like. in: [0003] GPS positioning technology is mainly used when the positioned user is outdoors. It can provide the positioning user with its own location information, and can also pro...

AI Technical Summary

Problems solved by technology

There may be multiple frequent GPS / AGPS positioning failures, resulting in a longer time to obtain the location information of the positioned user, and the terminal equipment of the positioned user is time-consuming and power-consuming but cannot obtain accurate location information in a relatively short period of time; and A large number of GPS / AGPS positioning falls back to base station positioning, which also increases the pressure on positioning platforms that provide base station positioning methods (referred to as base station positioning platforms in this application document)

[0007] In the existing technology, the positioning system adopts GPS / AGPS positioning technology and base station positioning technology. If the GPS / AGPS positioning fails and falls back to the base station positioning method, it may lead to a long positioning time, and multiple times on the terminal equipment side and the base station positioning platform side. Participate in GPS / AGPS positioning and base station positioning, but the user who initiated the positioning obtains location information with low positioning accuracy
