PURPOSE: A communication terminal for a terminal state management method is provided to prevent unnecessary VoIP call receiving process to a communication terminal which escaped a WLAN service area. CONSTITUTION: A WLAN(Wireless Local Area Network) module(150) performs a local communication with a WLAN AP(Access Point). A WLAN connection manager(130) manages a connection between the WLAN module and the WLAN access point. When a signal strength of the WLAN access point gets smaller than a first threshold value, the WLAN connection manager informs the signal strength. If the notification is received, a VoIP client(140) cancels a VoIP registration with the communication network.
