System and method for identification of transmitters with limited information
First Claim
1. A method for the identification of a base station in a wireless communication system, comprising:
- receiving complete identification data from a first base station;
receiving transmissions from a plurality of base stations, the transmissions containing only partial identification data insufficient to identify at least a portion of the plurality of base stations;
generating a candidate list providing identification of candidate base stations from which the transmissions containing only partial identification data may have been received;
analyzing the candidate base stations with respect to base stations that have been uniquely identified; and
determining the identity of a base station based on the analysis of the candidate base stations.

Abstract
A system and method are disclosed by which a base transceiver station (BTS) may be uniquely identified. When attempting to determine the location of a mobile unit using signal from multiple BTSs, it is critical that the BTSs be uniquely identified and their position accurately determined. In many cases, the signals received from the BTSs provide limited identification information and cannot be used to uniquely to identify the BTS from which a signal has been received. The present invention uses available information to generate a candidate list and to determine therefrom the most likely candidates for the Measurement BTSs. Based on this information, the system analyzes cell coverage overlap and relative phase delay to determine the likelihood of a candidate BTS being the actual BTS from which a signal is received. As candidate BTSs are uniquely identified, it is possible to use this additional identification information in an iterative process to further identify additional candidate BTSs.
