Abstract: In a simplified portable telephone system having a small radius of a radio zone, a channel switching failure during high-speed movement or an instantaneous disconnection at the time of switching often occurs. Judgment is made upon whether a mobile station moves at high speed or low speed based on a degree of reduction in an electric field intensity of a channel currently used for a telephone call, and a radio base station having an electric field intensity, which is above a specified value and shows a largest increases is selected froze surrounding radio base stations which can be a target of channel switching during high-speed movement, thereby performing channel switching.

Abstract: In a portable telephone set comprising a receiver for generating an audible tone, a vibrator for vibrating the portable telephone set mechanically, and a radio section for receiving an incoming call signal to produce a call detection signal, a transmitter microphone senses, in cooperation with a voice processing section, ambient sounds to produce an ambient sound level signal. In cooperation with a main control section, a vibrator control section selectively activates, in response to the call detection signal, one of the receiver and the vibrator with reference to the ambient sound level signal. When the level is not more than a predetermined level, the vibrator control section drive the vibrator to make the vibrator vibrate mechanically without generation of the audible tone. Otherwise, the vibrator control section makes the receiver generate the audible tone.
