METHOD AND SYSTEM FOR TRACKING THE POSITION OF MOBILE COMMUNICATION TERMINAL

摘要

The present invention relates to a system and method for tracking the position of a mobile communication terminal, which can minimize a position tracking error that may be produced upon tracking the position of the mobile communication terminal due to a propagation delay time in a repeater for transmitting and receiving a reverse or forward signal between the mobile communication terminal and a base station. The position tracking system of the present invention comprises a repeater (200) that relays a signal between the terminal (100) and the base station (400) and includes a terminal discriminating device (300) for receiving information from the base station (400) to determine whether the user terminal (100) is present; and a position tracking server (500) that tracks the position of the user terminal and includes a database (510) for storing geographical position information on the respective repeaters based on repeater identification information. According to the present invention, it is possible to minimize a position tracking error which may be produced upon tracking the position of the mobile communication terminal due to a propagation delay time caused by the repeater and to provide efficient position-based services such as urgency and emergency rescue services, and the like.
