Selective Location Determination

摘要

Methods, program products, and systems for selective location determination are described. A mobile device can determine a location of the mobile device using various techniques. When there is a conflict between the locations determined using different techniques, the mobile device can select a most trustworthy location from the locations, and designate the most trustworthy location as a current location of the mobile device. The mobile device can determine a first location of the mobile device (e.g., a coarse location) using a cell identifier (cell ID) of a cellular network. The mobile device can determine a second location of the mobile device (e.g., a fine location) using one or more media access control (MAC) addresses of a WLAN. The first location and second location can be associated with confidence values that can indicate trustworthiness of the first location and second location.

主权项

1. A method executed by a computer, including:
receiving a set of raw locations from one or more location-aware mobile devices located in a cell of a cellular communications network; determining a cell location to be associated with the cell using the set of raw locations; determining a confidence value of the cell location, the confidence value being proportional to a weighted average of a number of raw locations in the set and a stability of the cell, wherein the stability of the cell including a length of time during which the cell location is unchanged; and providing the cell location in association with the confidence value to a mobile device.
