Embodiment Construction

[0035] Because in the prior art, the position information of the reference equipment stored in the positioning server needs to be adjusted by artificially regularly updating the method, so when the position of the reference equipment changes, the position information of the reference equipment stored in the positioning server will be adjusted again. Before being adjusted, the positioning accuracy of the mobile terminal will be reduced. The embodiment of the present invention aims to eliminate the impact of reference devices with large position changes on the positioning results. The specific method is: after finding the position information corresponding to the identification information of each reference device uploaded by the mobile terminal, perform a search on each found position information Spatial clustering, locates the mobile terminal according to the location information contained in the class with the largest weight. Since the spatial clustering of each location info...

Abstract

The invention discloses a positioning method, device and system for solving the problem of relatively low accuracy for positioning a mobile terminal in the prior art. The method comprises the following steps: receiving identification information of each benchmark device uploaded by the mobile terminal and finding position information corresponding to the identification information of each benchmark device; spatially clustering the found position information; determining a sum value of trust degree corresponding to the position information contained in a class by aiming at each class after spatial clustering and taking the determined sum value as a weighting of the class; and positioning the mobile terminal according to the position information contained in the largest class. Because the position information with closer distance can be clustered into one class when being spatially clustered, the influence of the benchmark device with larger position changes on the positioning result can be eliminated to a certain extent so as to improve the positioning accuracy when the positioning is carried out according to the position information contained in the class with the largest weighting.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a positioning method, device and system. Background technique [0002] With the wide application of mobile Internet technology, the positioning function of mobile terminals is becoming more and more popular, how to improve the accuracy of positioning of mobile terminals has become an urgent problem to be solved. [0003] In the prior art, the method for locating the mobile terminal is as follows: figure 1 shown. figure 1 The process of positioning the mobile terminal in the prior art specifically includes the following steps: [0004] S101: The mobile terminal determines identification information of surrounding reference devices. [0005] Wherein, the reference device information includes devices such as base stations and wireless routers. The mobile terminal first collects the signals sent by the surrounding reference devices, and determines the identificatio...
