Claim Text:
1. A method comprising: obtaining, by a server computer, an initial location estimate of a mobile station to which a wireless network provides telecommunications service; receiving, by the server computer, a measurement report of a first signal that is received by the mobile station; deducing, by the server computer, a degree of proximity, P ii)) assigned to the first identifier prior to the receiving of the measurement report, and iii) considered invalid by the wireless network, in that the first identifier is consequently to be disregarded by the wireless network for handoff purposes; if the signal-strength information corresponding to the first identifier is absent from the measurement report for a given transmit strength of the first signal, increasing the transmit strength of the first signal according to a series of steps; correlating the series of steps of increased transmit strength with a series of received measurement reports, in order to determine when the signal-strength information corresponding to the first identifier becomes present from a predetermined subset of measurement reports in the series; and generating, by the server computer, a location estimate of the mobile station based on i) the deduced degree of proximity, P
