ABSTRACT:
A method for determining the position of a mobile station within a cellular telephone system having a plurality of base stations. A signal is transmitted from a rotating antenna. The rotating antenna has a beam which rotates around a cell in the cellular telephone system. The beam has a rotational timing that is known by the mobile station. The signal is received at the mobile station. Based on a reception time when the signal is received by the mobile station, an angular displacement value corresponding to the position of the mobile station is determined. A first round trip signal propagation time between a stationary antenna and the mobile station is measured using a voice information signal. The position of the mobile station is determined in accordance with the angular displacement value and the first round trip signal propagation time.
A method for determining the position of a mobile station within a cellular telephone system having a plurality of base stations. A voice information signal is transmitted from the mobile station. The voice information signal is received with a first antenna having a rotating beam for receiving the signal. Based on a reception time when the voice information signal is received by the first antenna, an angular displacement value corresponding to the position of the mobile station is determined. A first round trip signal propagation time between a second antenna and the mobile station is measured. The position of the mobile station is determined in accordance with the angular displacement value and the first round trip signal propagation time.
