TECHNIQUES FOR SELECTING SPS MEASUREMENTS TO USE IN DETERMINING A FINAL LOCATION ESTIMATE BASED ON A WLAN-BASED LOCATION ESTIMATE

摘要

In one embodiment, a mobile device detects one or more wireless local area network (WLAN) access points (APs) and a WLAN-based location estimate is determined for the mobile device using a wireless local area network based positioning system (WLAN-PS). The WLAN-based location estimate is based on the one or more detected WLAN APs and information maintained in a reference database associated with the one or more detected WLAN APs. The mobile device also obtains a plurality of satellite-based positioning system (SPS) measurements. A selection of a set of SPS measurements is made from the plurality of SPS measurements based on consistency of the set of SPS measurements with the WLAN based location estimate. The selected set of SPS measurements is used in determining a final location estimate of the mobile device.

1. A method comprising:
detecting, by a mobile device, one or more wireless local area network (WLAN) access points (APs); determining a WLAN-based location estimate for the mobile device using a wireless local area network based positioning system (WLAN-PS), the WLAN-based location estimate based on the one or more detected WLAN APs and information maintained in a reference database associated with the one or more detected WLAN APs; obtaining, by the mobile device, a plurality of satellite-based positioning system (SPS) measurements; selecting a set of SPS measurements from the plurality of SPS measurements based on consistency of the set of SPS measurements with the WLAN based location estimate; and using the selected set of SPS measurements in determining a final location estimate of the of the mobile device.
