Abstract
Mobile devices are able to determine their location based radio transmitters that are visible at the device to provide geographic location services. A knowledge of the location of the transmitters is required for the mobile device to determine a location estimate, however this can be difficult in network environments where the transmitters are temporary and their locations are not identified in location databases. Locations of temporary transmitters can be provided to mobile devices in order to augment the available location data used in determining the mobile device location. 3parties can provide temporal location data on transmitters that are set up for short period of time, as well as better control the distribution of the location data.
