The mobile node has a function of interfacing with networks and includes a network quality monitor, a hand-over controller, and a network controller. The network quality monitor operates to monitor a network quality based on at least one of an intensity and a radio bandwidth of a radio wave received by network devices. The hand-over controller performs the hand-over operation of transmitting a care of address to an address registering destination in response to a state of the network quality before a communication is disconnected, changing a route of communication information, and switching a connecting destination into a new network.

Abstract: A mobile terminal which can use a plurality of communication mediums enabling a wireless call by dynamically switching between the plurality of communication mediums during a call. When the condition of communication realized by a call-through-LAN unit deteriorates and deviates from a predetermined criterion during a first call through the call-through-LAN unit, the call switch unit establishes a connection through the call-through-telephone-network unit, and switches from the first call to a second call through the call-through-telephone-network unit. Thereafter, when the condition of communication realized by the call-through-LAN unit is restored to satisfy the predetermined criterion during the second call, the call switch unit switches from the second call to a third call through the call-through-LAN unit.

Abstract: As a result of a power saving technique for a portable dual terminal equipped with both WLAN unit and PHS unit, a call is usually relayed from an S-P gateway to a call receiver terminal via the PSTN, thereby incurring a call charge to the caller. According to the present invention, the call from the S-P gateway to the call receiver terminal (dual terminal) is terminated before a call charge is incurred, and the call receiver terminal calls back the S-P gateway via the IP network or the PSTN. The SIP server, instead of the call receiver terminal, identifies the caller terminal to call back, thereby connecting the call from the call receiver terminal to the caller terminal. In addition to this “callback method”, the present invention further provides “reconnection method”, “reconnection plus call-again method”, and “call-again method”, thus offering four types of methods.

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.
