摘要
An apparatus and a method for estimating the position of a mobile communication terminal, which improve the position estimating function by combining network based position estimating methods in a cellular network using CDMA (Code Division Multiple Access) comprises: a mobile communication exchanger for receiving a signal transmitted/received between a mobile communication terminal and respective base station; a position calculation unit including an angle of arrival (AOA) calculation unit for calculating an arrival direction of the signal, a time of arrival (TOA) calculation unit for calculating a distance between the mobile terminal and the base station using an arrival time of the signal, and a time difference of arrival (TDOA) calculation unit for calculating a distance between the mobile terminal and the base station using an arrival time difference of the signal; and a position deciding unit for deciding a position calculated by combining the values calculated in the position calculation units as the position of the mobile terminal.
