Continuous data optimization of moved access points in positioning systems
First Claim
1. A method of identifying a WiFi access point that is suspected to have moved relative to location information associated with the WiFi access point which is recorded in a reference database, the method comprising:
- at least one of a mobile WiFi-enabled device and a server system in communication with the mobile WiFi-enabled device receiving information identifying at least one WiFi access point in range of the mobile WiFi-enabled device;
at least one of the mobile WiFi-enabled device and the server system in communication with the mobile WiFi-enabled device accessing a reference database to retrieve location information associated with the identified WiFi access point recorded in the reference database, the location information specifying a previously-determined approximate location of the identified WiFi access point;
at least one of the mobile WiFi-enabled device and the server system in communication with the mobile WiFi-enabled device comparing the recorded location information associated with the identified WiFi access point to location information associated with WiFi access points observed by the mobile WiFi-enabled device during a period of time to infer whether the identified WiFi access point has moved from its previously-determined approximate location that is recorded in the reference database, the inferring including determining whether (a) the recorded location information associated with the identified WiFi access point is more than a threshold distance from the location information associated with WiFi access points observed by the mobile WiFi-enabled device during the period of time or (b) the recorded location information associated with the identified WiFi access point is within the threshold distance from the location information associated with WiFi access points observed by the mobile WiFi-enabled device during the period of time.

Abstract
Methods and systems of continuously optimizing data in WiFi positioning systems. A location-based services system uses WiFi-enabled devices to monitor WiFi access points in a target area to indicate whether a WiFi access point has moved relative to its previously recorded location. A WiFi-enabled device communicates with WiFi access points within range of the WiFi-enabled device so that observed WiFi access points identify themselves. A reference database is accessed to obtain information specifying a recorded location for each observed WiFi access point in the target area. The recorded location information is used for each of the observed WiFi access points in conjunction with predefined rules to infer whether an observed WiFi access point has moved relative to its recorded location. The reference database is informed of the identity of any observed WiFi access point that is inferred to have moved.
