Abstract: A communication system comprises a reference base station which collects one or more signal features of a mobile station signal. The reference base station determines a first location parameter of the mobile station signal it receives. The reference base station forwards the signal features to an auxiliary base station. Using the signal features, the auxiliary base station creates a replica of the mobile station signal as transmitted by the mobile station. The auxiliary base station correlates the replica with a same mobile station signal as received at the auxiliary base station in order to determine a second set of signal features. The auxiliary base station uses the second set of signal features to determine a second location parameter. The position of the mobile station is determined using the first and second location parameters.
