摘要： Disclosed is a technique allowing a communication terminal, even after a handover between different types of networks, to determine whether a communication that was in progress in an access network connected before the handover can be resumed or not. In order to receive an incoming CS call during a connection to a PS domain (E-UTRAN 101), a user terminal (UE 100) has to connect to a CS domain (UTRAN 102). When the UE has a LIPA (local IP address) in the PS domain, for example, the UE may not continue LIPA traffic in the CS domain after the CS call. In the present invention, a network performs buffering of LIPA traffic for certain duration, for example, and informs the UE of this condition, whereby the UE can securely determine whether the LIPA traffic is still kept after the CS call.

摘要： A path switching system is provided, in which when UE has been offloaded from a first PDN-GW to a second PDN-GW, if there is an additional connection of the UE to the first PDN-GW, processing related to the additional connection can be performed on the UE side. The system includes: a control unit for sending a mobile terminal a message including information indicative of having switched relay devices, which relay a packet between the mobile terminal and a communication device, from a first relay device to a second relay device; and the mobile terminal for determining whether there is an added path other than part of a path from the mobile device before movement to the communication device and capable of being managed by the control unit, established between the mobile terminal and the first relay device, and when there is the added path, performing processing on the added path.

摘要： The invention provides a technique to reduce a packet size of signaling to request vertical handoff in case a mobile node has static vertical handoff rules. According to this technique, MN 500, which has an If1, a WiMAX If2 and a WLAN If3, each being communicable with a PMIPv6 domain 511, roams within the PMIPv6 domain 511, and when the WiMAX If2 or the WLAN If3 is selectively and newly connected to WiMAX or WLAN, a prefix P2 to uniquely transfer the prefix P1 relating to If1 without transferring the prefix P1 relating to If1 to the WiMAX-If2 and the WLAN-If3, and to uniquely transfer from the WiMAX If2 previously connected or the WLAN If3 previously connected to the WiMAX If2 or the WLAN If3 newly connected to the LMA/HA 512 so that ID's of If2 and If3 are not contained in a trigger message of the vertical handoff as transmitted by MN 500.

摘要： Disclosed is a technique for surely supporting multihoming for a mobile terminal (mobile node) moving in a local mobility domain. A mobile node (MN) 11 connects via an IF 110 to a mobile access gateway (MAG) 102 that supports multihoming, and further attempts to connect via an IF 111 to a MAG 103 that does not support multihoming. Under these conditions, according to this technique, when the MN recognizes that the MAG 103 does not support multihoming, the MN notifies a local mobility domain that the MAG 103 does not support multihoming if connection with the MAG 103 is not yet established, and notifies the local mobility domain of information on a connection to a local mobility domain other than the MAG 103 (connection with the MAG 102) if the connection with the MAG 103 is already established.

摘要： Disclosed is a technique to, when a mobile node including a plurality of interfaces roams in a home domain, reduce signaling to create a client-based binding cache in a home agent and manages the same. When a MN (10) refers to a home MIPv6 prefix (P1) via an interface (If1) to find attachment to a home MIPv6 domain, the MN (10) predicts a high probability that another WLAN interface (If2) of the MN (10) connects with the same home MIPv6 domain (100) and an LMA/HA (40) and transmits a CMIPv6 cache creation•maintenance/management request message (308) to the LMA/HA (40). Receiving the request message (308), the LMA/HA (40) creates a CMIPv6 cache relating to the PMIPv6 cache of the WLAN interface (If2) and maintains/manages the CMIPv6 cache without being refreshed by the MN (10).
