Abstract

A method for determining the position of a mobile station (820) within a cellular telephone system having a plurality of base stations (810). A signal is transmitted at a low power level from the mobile station (820). The strength of the signal is then temporarily increased from the low power level to an increased power level, and the signal is temporarily transmitted from the mobile station (820) at this increased power level. While the signal is being temporarily transmitted from the mobile station (830) at the increased power level, the signal is used to make at least a first positional measurement. The position of the mobile station (830) is determined in accordance with the first positional measurement.
