AI Technical Summary

Problems solved by technology

The TOA positioning method uses the attenuation formula of the level signal for positioning. The measurement accuracy is greatly affected by parameters and the environment, and the accuracy is average; the triangulation positioning method directly finds the midpoint of the three base stations around the MR to locate, and the accuracy is poor; multi-reference point positioning The law assists positioning calculation by laying out fixed reference points, which is more accurate, but requires higher real-time calculations. Due to the limited number of reference points, the positioning backfill rate is very low

Abstract

The invention discloses a base station fingerprint database establishment method and device, a server and a storage medium. The method comprises the following steps: extracting longitude and latitudeinformation of a base station; generating a first grid according to the longitude and latitude information; obtaining first MR data carrying first position information in MR data uploaded by a terminal from the base station; adjusting a first grid into a second grid according to a preset relationship between the first MR data and the first grid; and generating a base station fingerprint database according to the first MR data in the second grid. According to the technical scheme, the effect of generating the grid size in a self-adaptive mode is achieved.

Description

technical field [0001] The embodiments of the present invention relate to the field of communications, and in particular to a method, device, server and storage medium for establishing a base station fingerprint library. Background technique [0002] In the communication network data, in order to locate the user in real time, MR (user equipment measurement report, hereinafter referred to as MR) data can be used to correlate with the core network XDR data, and the data with longitude and latitude position information in the MR data (hereinafter referred to as AGPS data) to assist user positioning. Since most users have not turned on the GPS function for a long time, AGPS data only accounts for about 3%-5% of the overall MR data volume. The MR data is used to backfill the latitude and longitude location information. [0003] Traditional positioning algorithms include TOA positioning method, triangulation positioning method and multi-reference point positioning method. The TO...
