Abstract
A wireless communication positioning method for determining the position of a mobile station when connecting to a base station. The coordinates of the mobile station are estimated according to the geomagnetic field strength measured by the mobile station, and the distance between the base station and the mobile station. The present invention further provides a method for solving the problem of acquiring two or more possible coordinates using the positioning method. The correct coordinates of the mobile station are determined by relocating the mobile station using the same method when the mobile station moves to another position aided by a direction of movement detected by the mobile station.
