MOBILE STATION INCORPORATING RADIO COMMUNICATION FUNCTION AND POSITION DECISION FUNCTION AND RECEPTION METHOD FOR POSITION DECISION SIGNAL BY THE SAME

摘要

PROBLEM TO BE SOLVED: To inexpensively provide a mobile station having a radio communication function and a position decision function. SOLUTION: The mobile station of a digital cellular radio communication system contains a means 3 transmitting a radio communication signal in a time divisional multiplex connection mode, a reception means 2, a means for receiving a position decision signal emitted by a position decision system and a means 4 processing the radio communication signal and the position decision signal. The processing means 4 is constantly connected to the radio communication signal transmission means 3, the reception means 2 and the position decision signal reception means 2. The processing means 4 uses the position decision signal received during time when the radio communication signal is not transmitted/received.
