Patent ID: 8462745

Claim:
A method of increasing the accuracy of a resulting location estimate for a WLAN and cellular enabled device using cellular positioning information, the method comprising: identifying at least one wireless local area network (WLAN) access point (WLAN AP) in signal range of a WLAN and cellular enabled device based on wireless signals received by the WLAN and cellular enabled device transmitted by the at least one WLAN AP; retrieving an estimated location of the at least one WLAN AP stored in a reference database; determining a cellular-based location estimate for the WLAN and cellular enabled device based on cellular measurements received from at least one cell tower by the WLAN and cellular enabled device; comparing the cellular-based location estimate to the estimated location of the at least one WLAN AP retrieved from the reference database to determine whether the estimated location of the at least one WLAN AP is outside a coverage area of the at least one cell tower; upon the condition that the estimated location of the at least one WLAN AP retrieved from the reference database is outside the coverage area of the at least one cell tower, inferring that the estimated location of the at least one WLAN AP is inaccurate; and rejecting the at least one WLAN AP that is inferred to be inaccurate when determining the resulting location estimate for the WLAN and cellular enabled device based at least on the cellular-based location estimate.
