Patent ID: 7233799

Claim:
A method comprising: receiving (i) a first signal measurement for a first signal as received by a wireless terminal, and (ii) a second signal measurement for a second signal as transmitted by said wireless terminal; generating a first multi-dimensional probability distribution for the location of said wireless terminal based on said first signal measurement; generating a second multi-dimensional probability distribution for the location of said wireless terminal based on a comparison of said second signal measurement to a predicted value of said second signal measurement; and estimating the location of said wireless terminal based on (i) said first multi-dimensional probability distribution, and (ii) said second multi-dimensional probability distribution; wherein estimating the location of said wireless terminal comprises: pruning a first list of candidate locations for said wireless terminal to a second list of candidate locations of said wireless terminal based on said first signal measurement; and choosing an estimated location for said wireless terminal based on said second list of locations and said second signal measurement.
