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.
