Abstract

According to the positioning method and device and the processor readable storage medium provided by the invention, firstly, the target terminal and the reference terminal respectively receive the positioning auxiliary measurement configuration information sent by the positioning server and the positioning auxiliary signal sent by the positioning base station, and respectively carry out positioning information measurement; obtaining corresponding TDOA (Time Difference Of Arrival) measurement information and carrier phase measurement information; and then, the TDOA measurement information and the carrier phase measurement information of the target terminal and the reference terminal and the reference position information of the reference terminal are combined to carry out positioning calculation processing, and the position information of the target terminal is obtained. When the position information of the target terminal is positioned, the TDOA measurement information and the carrier phase measurement information are combined, so that compared with a mode of positioning by adopting single TDOA measurement information in the prior art, the method has the advantages that the positioning measurement error is inhibited, the positioning precision is effectively improved, and the high-precision positioning requirement is met.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a positioning method, device and processor-readable storage medium. Background technique [0002] Based on Time Difference of Arrival (TDOA for short) is a positioning method defined in the 3GPP protocol specification. [0003] In the existing positioning method based on TDOA, the terminal will receive the positioning signals of multiple base stations, and calculate the TDOA measurement value of the signal according to the positioning signal, so as to obtain the distance of the terminal relative to each terminal according to the TDOA measurement value, and determine the terminal s position. [0004] However, there are various measurement errors in the positioning method based on TDOA, which will make the error range of the position of the terminal larger, and cannot meet the high-precision positioning requirements. Contents of the invention [000...
