PURPOSE: An emergent calling method using a mobile communication terminal is provided to simultaneously call plural parties without informing the outside of an emergent call in an emergency, thereby coping with various crimes. CONSTITUTION: When a user presses an emergent hot key, a controller confirms that the emergent hot key is inputted(S1). The controller prevents a speaker from being driven(S2), while prohibiting a display window from being driven(S3). The controller reads telephone numbers to be called in an emergency(S4), and converts the telephone numbers into emergency notify messages(S5), then transmits the messages to a base station(S6). A base station receives the messages(S7), and confirms the telephone numbers(S8), then calls each receiver corresponding to the telephone numbers(S9). If responses are received from the receivers(S10), the base station reads a voice message which informs of the emergency(S11), and transmits the voice message to the receivers such that the receivers perceive the emergency(S12). |
