MOBILE STATION AND METHOD OF LOCATING THE MOBILE STATION

摘要

Within a cellular radio communication system a method and a mobile station for use in locating the position of the mobile station relative to neighbouring base stations is provided. The mobile station and method use a mobile-station-based measurement approach and time-difference-of -arrival (TDOA) techniques to carry out location measurements. The method does not require the sending of special signals for the purpose nor any inter-base-station communication, but relies entirely on types of signals normally transmitted by the base stations. An embodiment in a TETRA based system is disclosed.
