ABSTRACT:
An antenna of a wireless interface is installed in a communications suppressing area, and a communications suppressing signal is transmitted. When a wireless telephone device receives this signal, its operation mode set to suppression mode so that when a call is received, an absence notification message is notified automatically. Area information indicating the kind of place the communications suppressing area is provided in the communications suppressing signal, and the absence notification message is generated according to this information. When a call is received during the suppression mode, selection of a response operation is prompted and, if selected, the selected response operation is performed. When a suppression releasing signal is received from an antenna installed in a non-communications suppressing area, or when the duration over which the communications suppressing signal is not received exceeds a preset period, the operation mode is switched from the suppression mode to the communications mode.
