Claim:
A system for preventing misappropriation of an urgent call through a mobile communication network, the system comprising: a rescue requester device adapted to send an urgent request signal containing urgent situation information during an occurrence of an emergency situation, the rescue requester device including a first controller which controls operation of the rescue requester device and precludes an audio signal when communication between the rescue requester device and one of a rescuer device and a security server is established when the urgent request signal is generated; the rescuer device as a primary emergency contact point, adapted to receive the urgent request signal, the rescuer device including a second controller which outputs an urgent ring tone if an urgent ring tone output request signal is generated when the urgent request signal is received, determines a sound volume of a rescuer device speaker, controls the sound volume of the rescuer device speaker to be increased to a maximum level; a communication company server in communication with the rescue requester device and adapted to receive the urgent request signal from the rescue requester device and transfer the urgent request signal to the rescuer device to thereby enable communication between the rescue requester device and the rescuer device, the communication company server including a third controller which controls operation of the communication company server and enables transmission of at least the urgent request signal to the rescuer device and also a communication signal to be sent from one of the rescuer device and the security server; and the security server in communication with the rescue device and adapted to receive an urgent information signal from the rescuer device to thereby enable communication between the rescue requester device and a secondary emergency contact point in a single-direction reception state through the communication company server so that the secondary emergency contact point communicates with the rescue requester device, wherein the urgent information signal includes a telephone number of the rescue requester device, messenger identification of the rescuer device and a receipt number of an accident, wherein the communication company server switches a call connection between the rescue requester device and the rescuer device to a call connection between the rescue requester device and the security server when the urgent information signal is transferred from the rescuer device to the security server.
