Embodiment Construction

[0041] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0042] like figure 2 As shown, in order to be able to locate more reliably and meet the requirements for positioning accuracy, the positioning method of the present invention includes the following steps:

[0043] a. Using the mobile terminal to acquire information about the communication base station, the acquired communication base station information includes the cell number (LAC) to which the base station belongs, the base station's own number (CID) and the signal strength attenuation value (RSSI);

[0044] Specifically, the mobile terminal includes a mobile phone, and may also be other equipment capable of communicating with a communication base station, such as a navigator. The acquired communication base station information also includes country code (MCC) and operator code (MNC).

[0045] b. Querying the communication base station database according ...

Abstract

The invention relates to an accurate locating method based on a communication base station. The method comprises the following steps that a. information of the communication base station is obtained through a mobile terminal, and the obtained information of the communication base station comprises a community number of the base station, a number of the base station and a signal intensity damping value; b. a communication base station database is inquired, and the longitude and latitude coordinate values of each obtained communication base station are obtained; c. according to the signal intensity value between the mobile terminal and each communication base station and sending power corresponding to each communication base station, the direct proportion distance between the mobile terminal and each communication base station is estimated; d. according to the direct proportion distance between the mobile terminal and each communication base station, a locating weight value corresponding to each communication base station is computed; and e. the locating weight value of each communication base station and the longitude and latitude coordinate values of each obtained communication base station are used for computing the position of the mobile terminal. According to the method, operation is convenient, locating deviation can be reduced, locating accuracy is improved, adaptability is high, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to a positioning method, in particular to a precise positioning method based on a communication base station, specifically a method for coordinated positioning of multiple communication base stations, belonging to the technical field of base station positioning. Background technique [0002] In recent years, with the development of technology, people's demand for positioning in indoor and outdoor environments is getting higher and higher, especially in some special cases, timely and accurate positioning of targets is particularly important. [0003] At present, GPS satellite positioning has the highest positioning accuracy, and the accuracy can reach within 5m. However, GPS positioning has its conditions of use: satellite signals must be searched in an open environment, so the use of GPS positioning has limitations. [0004] In order to make up for the limitations of GPS positioning, an Assisted Global Positioning System (AGPS) u...
