Abstract
A system obtains geographic positions associated with location points of multiple user equipments (UEs) in a wireless network and receives Evolved Universal Terrestrial Radio Access Network (E-UTRAN) radio fingerprint data associated with radio measurements performed at the location points by the multiple UE or performed by eNodeBs associated with the multiple UEs. The system clusters the location points based on similarities between the E-UTRAN radio fingerprint data to create cluster boundaries and stores the geographic positions, cluster boundaries and the E-UTRAN radio fingerprint data in a database for future determination of UE geographic positions using the E-UTRAN radio fingerprint data. The system receives E-UTRAN radio fingerprint measurement data associated with a first UE in the wireless network and performs a lookup operation into the database to retrieve one of the geographic positions that corresponds to the E-UTRAN radio fingerprint measurement data. The system sends the one of the geographic positions to at least one of the first UE, an emergency or police call center, a geographic information system (GIS) server or a node external to the wireless network.
