Abstract

Determining a geo-location estimate of a mobile device determined based on detected radio transmitters needs to uniquely identify at least one of the visible cellular towers. The estimate may be improved if multiple cellular towers can be uniquely identified. However, mobile devices may not determine unique identifiers for each visible cellular tower based upon configuration of the cellular radio protocol stack implementation. It is possible to disambiguate non-unique parameters detected at a mobile device to unique IDs of the cellular towers to aid in geo-location. The disambiguation is accomplished using disambiguation information that is associated with the cellular tower the mobile device is currently camped on.
