PURPOSE: A system for tracking an accident occurring spot using a mobile communication terminal receiving a GPS satellite signal is provided to track a position of the mobile communication terminal in a ready room if an emergent call is made by using a mobile communication network, thereby quickly going into action to the accident occurring spot and exactly guiding to the spot by supplying position information. CONSTITUTION: A mobile communication terminal(20) receives a GPS signal, and delivers the GPS signal with an access signal for making a call with the other party. A communication network of a mobile communication provider consists of a repeater(32) and a base station(30). The repeater(32) transmits the access signal and the GPS signal. A receiver and position calculator(50) includes a GPS signal receiver(40) for receiving the GPS signal, receives the GPS signal while receiving the access signal, and analyzes the GPS signal to output a position value of the terminal(20). A display processor(55) displays the position of the terminal(20) by interworking with a map information DB, with the use of the outputted position value.
