Title:
SYSTEM AND METHOD FOR MEASURING AND LOCATING A MOBILE STATION SIGNAL IN A WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO2000011804
Kind Code:
A3
Abstract:
A communication system comprises a reference base station (110A) which collects on or more signal features of a mobile station signal. The reference base station (110A) determines a first location (120) parameter of the mobile station signal it receives. The reference base station (110A) forwards the signal features to an auxiliary base station (130). Using the signal features, the auxiliary base station (110B) creates a replica of the mobile station signal (132) as transmitted by the mobile station. The auxiliary base station (110B) 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. The process maybe repeated at a plurality of auxiliary base station (110B-110G) and for a plurality of different location parameters in order to improve the accuracy of the determination of mobile station location.
