Abstract:
A method and apparatus determines if a location fix received by a mobile station using a non-GPS location techniques is accurate. Location results obtained using the non-GPS location technique or techniques are treated as accurate if they are verified as being within an error margin obtained from a trusted source of location information such as a GPS positioning system. Non-GPS Location information may be obtained from a signal transmitted by the base station, which signal includes the base station location. The non-GPS location information may also be obtained from a backend service associated with the wireless network that includes the base station.
