Abstract
A mobile radio communication terminal automatically disconnects a call after completion of a telephone conversation. A speaker signal detector generates a first detection signal upon detection of an audio signal received from another party, and a microphone signal detector generates a second detection signal upon detection of an audio signal input from a microphone. A controller disconnects an established speech path when the first and second detection signals are not input from respective speaker signal detector and the microphone signal detector, for a predetermined time.
