PROBLEM TO BE SOLVED: To eliminate the need of continuously hearing a calling sound during the call of a user by detecting that a system is under the call after a communica tion destination is called and driving a vibration means. SOLUTION: A user directly inputs the telephone number of the communication destination from an input part 8 or retrieves a telephone number stored in a memory 9. Thus, a control part 5 recognizes the telephone number of a transmission destination, transmits it through an antenna and it is to execute communication with a desired opposite party. Then, a radio base station and a network control part connected to it recognize the opposite party and they move to a call operation. The terminal receiving a signal informing the call emits the calling sound from a reception part. At that time, it drives the vibration part 7 and vibrates the terminal. When an opposite side unit is off-hooked, the control part 5 recognizes it and the system moves to a call possible state. At that time, the control part 5 operates to stop the calling sound and to stop the driving of the vibration part 7. |
