ABSTRACT:
In a portable phone having installed therein a PHS and a WLAN, the PHS is used for standby as long as the PHS is in the coverage area. At the time of receiving an incoming call during standby by the PHS with only the PHS being ON, the power of WLAN is turned ON. If the WLAN is in the coverage area, the incoming call is once disconnected, and immediately a VoIP call is sent (call back) by the WLAN. At this time, the PHS is turned OFF. On the other hand, if the WLAN is out of the coverage area at the time of receiving the incoming call, the call is similarly disconnected, after which the WLAN is turned OFF and the VoIP call is sent by the PHS.
