Abstract: A method for determining the location of a mobile unit (MU) in a wireless communication system and presenting it to a remote party. The location of a remote MU is determined by comparing a snapshot of a predefined portion of the radio-frequency (RF) spectrum taken by the MU to a reference database containing multiple snapshots taken at various locations. The result of the comparison is used to determine if the MU is at a specific location. The comparison may be made in the MU, or at some other location situated remotely from the MU. In the latter case, sufficient information regarding the captured fingerprint is transmitted from the MU to the remote location. The database may be pre-compiled or generated on-line.

Abstract: Technique for determining the location of a mobile unit in a wireless communication system and presenting it to a remote party. In a scenario with first and second position estimates, the first position estimate is presented within a first predetermined time interval of call setup between the mobile unit and the remote party, and, if the second position estimate is available for presentation to the remote party, the second position estimate is presented within a second predetermined time interval after presentation of the first position estimate. Else, status information on availability of the second position estimate is presented within the second predetermined time interval.
