摘要:
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.
