    Abstract: A mobile communication terminal apparatus and a control method thereof wherein a smooth handoff can be quickly achieved in a seamless manner during a roaming between data communication networks of different packet exchange systems. A mobile communication terminal apparatus (100) comprising a network access unit (NAU) (101) having a network access mechanism that has been uniquely established by adjusting the specifications of hardware, software and protocols; and a MADU (Multiple Access Decision Unit) (103) that uses a set of interfaces to exchange information with the NAU (101), thereby deciding a channel to be used in a communication session, and that controls the NAU (101) corresponding to the decided channel; wherein the mobile communication terminal apparatus performs a roaming between data communication networks of different packet exchange systems.

    Abstract: A com m unications term inal registered as a controlled term inal in a controlling terminal which controls the controlled terminal via a communications network, the communications terminal includes a receiving unit (15020) which receives a sleep message including information indicating whether or not the controlling terminal is sleeping and information indicating a timing when the controlling terminal leaves sleep mode and wakes up; a detecting unit (15030) which detects a transmission of a registration request for requesting that a new terminal be registered in the controlling terminal as a new controlled term inal, the new terminal being another communications terminal not yet registered in the controlling term inal; and a notifying unit (15040) which determines whether or not the controlling term inal is sleeping based on the sleep message, and notifies the new terminal of the timing by sending the sleep message when the controlling terminal is sleeping and when the transmission of the registration request is detected.

    Abstract: Disclosed is a technique of, in a network conducting network based local mobility management, suppressing generation of signaling and an increase of processing load on a network entity and preventing a delay. According to this technique, a mobile node (MN 130) receives specific information (a token) including an interface identifier and a binding identifier, for example, from a network side (MAG 120) when connecting therewith first. When the mobile node conducts a handover, the mobile node notifies a next connecting MAG 122 of the token. The MAG receiving the token can judge based on this token whether the connection by the mobile node is due to a handover changing a connection point for a certain interface or due to a new connection using a different interface without making an inquiry to other network nodes.
