Problems solved by technology

[0003] The above-mentioned AOA positioning method is not suitable for cities with dense buildings. The TOA positioning method must measure the time it takes for three different radio transceivers to transmit signals to determine a position. The TDOA positioning method must also use at least three base stations. The intensity not only requires three base stations to measure at the same time, but also the measured value obtained will have a large error

Embodiment Construction

[0042] The present invention provides a method for positioning a wireless communication system, such as Figure 4 As shown, the system includes communication base stations 400-406 transmitting signals covering cells 406-410, and mobile communication terminal equipment 412. The mobile communication terminal equipment 412 is in the cell of any wireless communication positioning system to connect to a base station at any time, such as Figure 4 In this example, a mobile communication terminal device 412 is connected to a base station 402 in a cell 408 . The location of the base station can be obtained by other precise measurement methods, such as GPS positioning, and a set of latitude and longitude data during erection, and recorded in the system. The area covered by the base station signal can be obtained from the database of the communication service provider. Therefore, the mobile communication terminal device 412 can determine that the location of the mobile communication te...

Abstract

A wireless communication positioning system and its method, which is used to position a movable communication terminal connected with base station. And it can calculate the distance R between the terminal and base station, measure magnetic intensity in the terminal position and position the absolute coordinate of the terminal to serve as coordinate data of positioning service through wireless communication system base station coordinate, the data base of magnetic intensity in the sector of base station and transmitting data information by the terminal. The invention additionally solves the problem of re-positioning by the same method when there are more than one position. While again the result is more than one, the terminal will send back its moving direction to determine the right position.

Description

technical field [0001] The present invention relates to a positioning method and system, in particular to a geomagnetism-assisted wireless communication positioning method and a wireless communication positioning system. Background technique [0002] Currently known positioning technologies usually utilize wireless information transmitted between a plurality of radio transceivers and a mobile communication terminal device to determine the coordinate position of the mobile communication terminal device; and some known positioning technologies include, for example, figure 1 The angle of arrival of the signal (AOA--Angle of Arrival) is used to determine the position A of the mobile communication terminal equipment with the angles α1 and α2 formed by the two base stations S1 and S2 and the mobile communication terminal equipment; figure 2 As shown, the distance between the mobile communication terminal equipment and the base stations S1, S2, and S3 is calculated by using the ti...
