Abstract

Embodiments of the present invention provide a positioning method, a server, a base station, a mobile terminal and a system in a mobile network, which can be used for high-precision positioning of a mobile terminal. The positioning method includes: the server acquires first location information, and the first location information is used to indicate the location of the base station; the server acquires correction information for the base station according to the location of the base station; the server sends the correction information to the base station , so that the base station forwards the correction information to the mobile terminal, so that the mobile terminal determines the location of the mobile terminal according to the correction information. The server includes: an obtaining module, used to obtain the location information of the base station, and obtain correction information for the base station according to the location of the base station; a sending module, used to send the correction information to the base station, so that the base station can send the correction information to the base station The mobile terminal forwards the correction information, so that the mobile terminal determines the location of the mobile terminal according to the correction information.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and more specifically, to a positioning method, server, base station, mobile terminal and system in a mobile network. Background technique [0002] In the Long Term Evolution ("LTE") system, the standard methods of positioning mainly include: Assisted Global Navigation Satellite System (Assisted Global Navigation Satellite System, "A-GNSS") positioning, observed time difference of arrival (Observed Time Difference of Arrival, "OTDOA" for short) positioning and enhanced cell ID (enhanced Cell ID, "e-CID" for short) positioning, but none of the above three positioning methods can meet the demand for high-precision positioning. [0003] At present, in the national surveying and mapping industry, dynamic real-time kinematic ("RTK") technology is used to correct GNSS positioning information using carrier phase observation technology to obtain higher-precision positioning results. Howev...
