Abstract:
1. A method associated with a wireless network, the method comprising: receiving, by a data-processing system, reports on the signal strengths of wireless signals received by a wireless terminal from a plurality of antennas in the wireless network; evaluating, by the data-processing system, a plurality of factors based on the reports, wherein each factor is probative of whether the reported-on signals were received indoors by the wireless terminal; generating, by the data-processing system, an estimated probability that the reported-on signals were received indoors by the wireless terminal, based on the plurality of factors, wherein each factor is weighted according to a corresponding weight that is specific to the wireless network; and generating, based on the probability, an estimated first location for the wireless terminal, thereby eliminating, also based on the probability, a second location for the wireless terminal.
