GSM network consumer positioning method based on signal receiving strength information fingerprint

Abstract

The invention relates to GSM network positioning technical field and provides a GSM network consumer positioning method based on signal receiving strength information fingerprint, comprising following steps: step 1 establishing information fingerprint data-base in a plurality of acquisition points in a certain area coverage; step 2 intercepting the report of the consumer to the network when talking, extracting the signal receiving strength in the customer service cell and the adjacent cell; step 3 comparing the signal receiving strength and the information fingerprint errors in the information fingerprint database acquisition points, therefore, the consumer position is the geographic position where the information fingerprint error is minimum in the acquisition point. The positioning method does not change prior GSM system network structure and the consumer terminal hardware condition with low cost and positioning accuracy error less than 30 m and is suitable for positioning indoor / outdoor. The density of the acquisition points is flexibly adjusted based on the consumer actual positioning requirements.

Description

A method for locating users in GSM network based on signal reception strength information fingerprint technical field The invention belongs to the communication field, and relates to a method for locating call users in a GSM network, in particular to a method for locating users in a GSM network based on signal receiving strength information fingerprints. Background technique The GSM cellular network has developed very maturely, with more than 300 million users in China. With the continuous enrichment of business functions, providing users with positioning services is a business with great market prospects. The development of this technology and business should also be attributed to Regulation E-911. In order to improve the quality of public safety services for mobile users, the U.S. Federal Communications Commission (FCCFederal Communications Commission) issued the E-911 regulation in July 1996. Emergency call service), the service center can quickly and accurately determ...
