CERTIFIED LOCATION FOR MOBILE DEVICES

摘要

In one example embodiment, a Wi-Fi based location determination technique both determines one or more locations of a mobile device, and calculates a confidence score for each determined location. A request is received at a certified location service executing on a server for one or more locations of the mobile device and a data package. The data package may include an indication of a plurality of beacons observed by the mobile device. The certified location service determines one or more locations of the mobile device based on a calculated location of at least some of the plurality of beacons. The certified location service also determines a confidence score for each beacon used in determining each location. An overall confidence score for each determined location may be calculated based on a combination of the confidence scores for each of the beacons used in the determination of the location.

主权项

1. A method comprising,
receiving, at a server, a request for one or more locations of a mobile device and a data package, the data package including an identifier of a plurality of beacons observed by the mobile device, the plurality of beacons including at least an observed Wi-Fi access point (AP), an observed cell tower, or an Internet Protocol (IP) address assigned to the mobile device; determining, at the server, one or more locations of the mobile device based on a calculated location of one or more of the plurality of beacons; determining an individual confidence score for each beacon used in determining each location, the individual confidence score being an indication of a likelihood that the beacon is located at the calculated location; calculating an overall confidence score for each determined location based on a combination of the individual confidence scores for each of the beacons used in determining the location; and returning an indication of the one or more determined locations of the mobile device and the overall confidence score for each determined location.
