Abstract

The invention discloses a user positioning method and device. The method comprises the following steps: acquiring cell data and measurement report data; calculating a neighbor cell and a cell coveragerange of the cell according to the cell data; extracting an information fingerprint according to the measurement report data, the neighbor cells of the cell and the cell coverage area; and calculating the position of the user terminal according to the neighbor cell, the cell coverage area and the information fingerprint of the cell. According to the method, the user positioning accuracy is greatly improved, the resource use efficiency is improved, and the method is a basis for all position-related applications; The method can be applied to the FDD/TDD network, and the application range is wider.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a user positioning method and device. Background technique [0002] An LTE MR (Measurement Report, measurement report) positioning method uses RSRP (ReferenceSignal Receiving Power, reference signal receiving power) to evaluate the distance to obtain the distance evaluation from the neighboring cell to the user's location, and then use the triangulation algorithm to determine the user's location , this method has a large error in the RSRP evaluation distance, and the triangulation algorithm makes a plane approximation to the ground, resulting in low positioning accuracy. [0003] Another technical solution adopts the triangular positioning method of TA (Timing Advance, time advance), AOA (Angle-of-Arrival, angle-of-arrival, ranging), AOA is TDD (Time Division Duplexing, time division duplex) LTE (Long Term Evolution (Long Term Evolution) is a unique field in the network, but ...
