LOCATING A WIRELESS DEVICE BASED ON INFORMATION ABOUT BASE STATIONS BELONGING TO A PLURALITY OF NETWORKS

摘要

A method and system that allow the location of a wireless device are disclosed. Resolving the location in one embodiment relies upon accessing at least one cooperative base station and at least one uncooperative base station. The cooperative base station provides an almanac of base stations that are likely to be near the wireless device. Both cooperative and uncooperative base stations within range can be used to determine the location of the wireless device. The uncooperative base station is not generally available to the wireless device, but can be used to determine distance to the wireless device.
