| 摘要 |
The present invention relates to a device for tracking the position of a mobile unit in a mobile communication system by using beacons, wherein each beacon has its own sub-coverage in the cell coverage of a base transceiver station (BTS). The present invention resolves the problem of the conventional network-based or handset-based position tracking methods. By using beacon information included in a Pilot Strength Measurement Message (PSMM) signal, the present invention increases the accuracy of position tracking to thereby improve the quality of supplemental services in the mobile communication system.
