Abstract:
A telecommunications system for determining the location of a given one of a plurality of mobile terminals within a time division multiple access system, said telecommunications system comprising:a base transceiver station in wireless communication with said given mobile terminal, said base transceiver station being adapted to obtain at least first and second timing advance values associated with said given mobile terminal and receive a signal from said given mobile terminal; anda base station controller connected to said base transceiver station and adapted to determine an average timing advance value, said average timing advance value being determined by averaging said at least first and second timing advance values received by said base transceiver station, said average timing advance value being used to estimate a time of arrival of said signal from said given mobile terminal to said base transceiver station, said time of arrival being used to determine the location of said given mobile terminal.
