Abstract:
1. A method comprising: receiving, by a server computer: estimating, by the server computer, the location of the first wireless terminal based on the evidence of the location of the first wireless terminal; estimating, by the server computer, a first spatial displacement between the first wireless terminal and the first base station, based on the estimated location of the first wireless terminal; generating, by the server computer, a statistic by applying a corresponding, predetermined statistical algorithm to a data set, wherein a first value in the data set is based on i) the first spatial displacement and ii) the first propagation-time measurement, and wherein a second value in the data set is based on the second propagation-time measurement; estimating, by the server computer, the location of a second wireless terminal based on the statistic, resulting in a location estimate; and transmitting, by the server computer, the location estimate to a location-based application.
