Embodiment Construction

[0050] Relevant technical content and detailed description of the present invention, now cooperate accompanying drawing to explain as follows:

[0051] The invention provides a method for determining a user based on a GSM network based on signal reception strength information fingerprints. Firstly, the field information fingerprints are collected, and then the measurement report reported by the user to the network during the conversation is intercepted through the network, and compared with the information fingerprint database. Find the closest collection point to locate the user and provide positioning services for the user.

[0052] Such as Figure 6 The schematic diagram of the system structure on which the present invention is based is shown. First, some signal fingerprint collection points are selected according to needs within the coverage of the network, and the signal fingerprint collection work is done well. When the user makes a call, the application system can be u...

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

technical field [0001] 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 [0002] 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 E-911 regulations. 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. 911 emergency call service), the service center can quickly and accurately determine the location of the caller, so as to provide the public with more rapid and ef...
