Abstract
A device for tracking a mobile station's position in a mobile communication system. The device comprises a receiver for receiving single tone signals and positional information transmitted from at least three base stations; a tone phase measurer for measuring phase differences, dependent on propagation delay, of the tone signals on the basis of a base station's system reference time before propagation delay; and a mobile station's position calculator for calculating positional information of the mobile station using the measured phase differences and the positional information of the base stations.

A device for tracking a mobile station's position in a mobile communication system, comprising:
- a receiver for receiving tone signals form at least three base stations, and positional information of the base stations from the service base station;
- a tone phase measurer for measuring phase differences, dependent on propagation delay, of the tone signals on the basis of a base station's system reference time before propagation delay;
- and
- a mobile station's position calculator for calculating positional information of the mobile station using the measured phase differences and the positional information of the base stations.
