US 8284103 B2
1. A method of using a Wireless Local Area Network (WLAN) and satellite enabled device to infer that a reference location associated with a detected WLAN access point (AP) is not a present location of the WLAN AP, the method comprising:
identifying a plurality of WLAN APs detected by the WLAN and satellite enabled device;
accessing a reference database to obtain a reference location associated with each WLAN AP of the plurality;
receiving satellite measurements from at least two satellites;
receiving a hybrid position estimate for the device, the hybrid position estimate being based on the satellite measurements and at least one of the reference locations associated with at least one of the WLAN APs of the plurality;
estimating a distance between the reference location associated with at least one of the WLAN APs of the plurality and the hybrid position estimate of the device; and
inferring that the reference location associated with the WLAN AP for which the distance was estimated is not the present location of the WLAN AP based on the distance between the reference location associated with the WLAN AP for which the distance was estimated and the hybrid position estimate of the device.
2. The method of claim 1, further comprising indicating in the reference database that the reference location associated with the WLAN AP for which the distance was estimated is not the present location of the WLAN AP.
3. The method of claim 1, further comprising updating the reference location associated with the WLAN AP for which the distance was estimated in the reference database to reflect an estimated present location of the associated WLAN AP.
4. The method of claim 1, the inferring that the reference location associated with the WLAN AP for which the distance was estimated is not the present location of the WLAN AP being based on the distance between the reference location associated with the WLAN AP and the hybrid position estimate of the device exceeding a predetermined threshold.
logic for identifying a plurality of WLAN APs detected by the WLAN and satellite enabled device;
logic for accessing a reference database to obtain a reference location associated with each WLAN AP of the plurality;
logic for providing satellite measurements from at least two satellites;
logic for providing a hybrid position estimate for the device, the hybrid position estimate being based on the satellite measurements and at least one of the reference locations associated with at least one of the WLAN APs of the plurality;
logic for estimating a distance between the reference location associated with at least one of the WLAN APs of the plurality and the hybrid position estimate of the device; and
logic for inferring that the reference location associated with the WLAN AP for which the distance was estimated is not the present location of the WLAN AP based on the distance between the reference location associated with the WLAN AP for which the distance was estimated and the hybrid position estimate of the device.
7. The system of claim 6, further comprising logic for indicating in the reference database that the reference location associated with the WLAN AP for which the distance was estimated is not the present location of the WLAN AP.
8. The system of claim 6, further comprising logic for updating the reference location associated with the WLAN AP for which the distance was estimated in the reference database to reflect an estimated present location of the associated WLAN AP.
9. The system of claim 6, the inferring that the reference location associated with the WLAN AP for which the distance was estimated is not the present location of the WLAN AP being based on the distance between the reference location associated with the WLAN AP and the hybrid position estimate of the device exceeding a predetermined threshold.
