Embodiment Construction

[0063] figure 1 It is a flowchart of Embodiment 1 of the terminal positioning method of the present invention. The terminal positioning method of this embodiment includes:

[0064] A. Obtain the cell information reported by the terminal and the signal strength information between each base station and the terminal under the coverage of the cell. In this step, the cell information is cell identification information, such as Lac (location areacode, location area code), cellid (cell ID);

[0065] B. Obtain the position information of each base station under the coverage of the cell according to the received cell information, and in this step, for example, obtain the position information of each base station under the coverage of the cell by a table look-up method;

[0066] C. Calculate the initial position information of the terminal according to the received signal strength information between each base station under the coverage of the cell and the terminal and the position in...

Abstract

The invention discloses a terminal positioning method and system. The terminal positioning method comprises the following steps of acquiring COO (cell of origin) information reported by a terminal and intensity information of signals among each base station covered by the COO and the terminal; acquiring position information of each base station covered by the COO; calculating the initial position information of the terminal; calculating the distance between the terminal and each base station, and adopting the base station nearest to the terminal as a target base station and the distance between the terminal and the target base station as a target distance; calling a target optimization database to acquire matching data of the target base station; and optimizing the initial position information of the terminal according to the acquired matching data to acquire the optimized position information of the terminal. A plurality of target base stations and corresponding matching data thereof are stored in the target optimization database in advance. The matching data are a set of target distances among a plurality of terminals and the target base station. By means of the technical scheme, the terminal positioning precision can be improved.

Description

technical field [0001] The present invention relates to the field of data communication, in particular to a terminal positioning method and system. Background technique [0002] There are many personal terminals on the market now, and there are various terminal positioning algorithms, such as GPS technology, A-GPS technology, WIFI positioning technology, and base station positioning technology. For GPS technology and A-GPS technology, because this technology is affected by factors such as weather and user's location, the time to realize positioning is relatively slow, and the positioning accuracy is poor when realizing positioning in indoor and other closed places. For WIFI positioning technology and base station positioning technology, the terminal needs to be able to connect to the Internet, upload the base station number to the designated server for query through the network, and realize the positioning function according to the query result, but the positioning technolog...
