Problems solved by technology

However, because the network RTK positioning technology needs to be based on the Continuously Operational Reference Stations ("CORS"), the current CORS system is only used in the field of surveying and mapping, and is not open to ordinary users, and its broadcasting capacity is limited, so it cannot accommodate Massive ordinary users of the mobile network

Abstract

Embodiments of the present invention provide a positioning method in a mobile network, a base station and a mobile terminal, capable of performing high-precision positioning on the mobile terminal. The positioning method includes: the first base station receives an RTK observation value for an RTK reference source; the first base station determines first correction information according to the RTK observation value, and the first correction information is obtained from a positioning system for the RTK reference source Correction information of positioning information: the first base station sends the first correction information to the first mobile terminal, so that the first mobile terminal determines the position of the first mobile terminal according to the first correction information. The base station includes: a receiving module, configured to receive an RTK observation value for an RTK reference source; a processing module, configured to determine first correction information according to the RTK observation value; a sending module, configured to send the first correction information to the first mobile terminal Correcting information, so that the first mobile terminal determines the location of the first mobile terminal according to the first correcting information.

Description

technical field [0001] The present invention relates to the communication field, and more particularly, to a positioning method, a base station and a mobile terminal 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" for short) technology is used to correct GNSS positioning information using carrier phase technology to obtain higher-precision positioning results. However, because the network RTK ...
