Embodiment 1

[0063] Figure 7 is a schematic diagram of base station positioning according to Embodiment 1 of the present invention, as shown in Figure 7 Shown is the relationship between the terminal to be positioned and each base station. Figure 8 is a flowchart of a positioning method according to Embodiment 1 of the present invention, such as Figure 8 As shown, the positioning method includes:

[0064] Step S802, receiving a positioning request sent by the terminal to be positioned, wherein the positioning request includes the Cell ID of the primary base station currently connected to the mobile terminal to be positioned, the Cell IDs of multiple neighboring cell base stations, and corresponding signal reception strength values.

[0065] In this step, the terminal to be positioned sends a positioning request to the positioning device through the mobile communication network, and at the same time obtains the connected base station information, and adds all the obtained base station...

Abstract

Disclosed are a positioning method and device. The method comprises: acquiring a positioning request of a terminal to be positioned, wherein the positioning request comprises a fingerprint of the terminal to be positioned, the fingerprint comprising identifiers of a main base station connected to the terminal and a plurality of base stations of neighboring cells and corresponding signal intensity receiving values; and calculating the similarity between fingerprints of other terminals in a fingerprint database and the fingerprint of the terminal to be positioned, and calculating a position of the terminal to be positioned through the positions of the other terminals according to the similarity, wherein the fingerprint database comprises fingerprints of a plurality of terminals and corresponding positions when the fingerprints are collected. By means of the present invention, the problem in the related art that the positioning effect is relatively poor in the case where a service end is unable to parse a position of a base station is solved, moreover, the positioning method has the advantages of high positioning accuracy and high positioning speed, and specifically, the positioning effect is greatly improved in the case where the service end is unable to learn the positions of all base stations and the density of the base stations is low.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a positioning method and device. Background technique [0002] In the traditional base station positioning method, the user can obtain the information of multiple base stations connected to the terminal through the mobile terminal, and send the location information of the base station to the positioning server through the mobile Internet, and the positioning server analyzes the location of the base station through the Cell ID of the base station. position information, or use the triangle algorithm to feed back the positioning results to the mobile terminal. At present, many location service manufacturers adopt this positioning method. [0003] For the current base station positioning methods in related technologies, the positioning accuracy is generally not high, usually only about 200-500 meters, and the drift phenomenon is very serious, it is difficult to ensure the positioni...
