Patent ID: 8391890

Claim:
A method for estimating a geographic location of a mobile station within a coverage area of a wireless network, comprising: determining a radial distance of a mobile station from a base station serving the mobile station, the base station including multiple sector antennas, the radial distance based at least in part on a round trip measurement associated with elapsed time between sending an outgoing signal from the base station to the mobile station and receiving a corresponding acknowledgement signal from the mobile station at the base station; and calculating a current angular position of the mobile station in relation to the radial distance from the serving base station based at least in part on a first signal strength measurement, a second signal strength measurement, and an angular position reference that extends outward from the serving base station, the first and second signal strength measurements representative of power characteristics of respective radio frequency (RF) signals received by the mobile station from corresponding first and second sector antennas of the serving base station; wherein the calculating of the current angular position of the mobile station is also based at least in part on first and second transmit parameter values representative of power characteristics of respective communication signals to be transmitted by the corresponding first and second sector antennas.
