MOBILE TERMINAL AND TERMINAL ACCESS METHOD

PROBLEM TO BE SOLVED: To provide a low price and simplified mobile terminal available for daily communications and transmission of messages for emergency. SOLUTION: A communication terminal 2 and a termination terminal 3 respectively have a telephone function. The communication terminal 2 is used, for example, by a parent (protector), and the termination terminal 3 is carried by a child. The communication terminal 2 is capable of sending, in principle, connection requests to the termination terminal 3 without any limitation. Meanwhile, the termination terminal 3 can extend connection requests only to the communication terminal 2 registered previously. When a communication button is depressed within a short period at the termination terminal 3, the termination terminal 3 sends a connection request to the communication terminal 2 but disconnects the line before the communication terminal 2 is connected. Thereby, the termination terminal 3 can leave the termination history in the communication terminal 2 without communication fee. In addition, when the communication button is depressed for a longer period at the termination terminal 3, the termination terminal 3 disconnects the line immediately after the communication terminal 2 is connected. Thereby, it is possible to call a parent to the communication terminal 2 with minimum communication fee. COPYRIGHT: (C)2008,JPO&INPIT
