Patent ID: 6944466

Claim:
A method of estimating mobile station location in a wireless communication system in which a mobile station communicates with a primary base station associated with a primary location processor, the method comprising the steps of: transmitting from the primary base station a message signal directing the mobile station to transmit a location signal, wherein the message signal comprises a location probe message signal directing the mobile station to transmit the location signal at a particular power level and for a particular duration, such that the mobile station returns its transmit power level to a power level utilized prior to sending the location signal after the location signal has been sent at the power level and duration indicated in the location probe message signal; detecting the location signal in the primary base station to generate a first path delay measurement; receiving additional path delay measurements generated based on detection of the location signal in a plurality of secondary base stations; and utilizing the first and additional delay measurements to estimate the location of the mobile station.
