摘要： When a mobile terminal transmitting/receiving a packet using a plurality of IP address types performs a handover to an access network (single address type connection network) permitting transmission/reception of a packet using a single IP address only, an IP address not permitted is unfortunately discarded at an access network as a handover destination. Disclosed is a technique configured so that a mobile terminal (UE 1) detecting a handover to the single address type connection network establishes a temporary connection with a mobility management gateway (PGW 5) and thereafter acquires an address of an ePDG 8 located at a core network and informs the ePDG of a communication state before the handover via a PDN using the temporary connection. The ePDG informs the PGW of the communication state of the UE before the handover. Thereby, the communication state of the UE before the handover is achieved with the PGW via the ePDG and the PDN.

摘要： A technique is disclosed whereby, in the case of wherein a communication node includes both a mobility management function and a multihoming function, based on a condition that occurs due to moving, an appropriate address can be selected from multiple addresses in a multihomed state. According to the technique, a mobility condition determination unit 126, provided in an MIP controller 120 that manages moving of a communication node, obtains and examines various conditions that has occurred as a communication node is moving, selects an appropriate HoA (e.g., the home address of an MN1) for the current connection situation, and transmits, to a multihoming controller 130, a notification indicating that a set of the selected HoA and a CoA is appropriate addresses to be used. Upon receiving the notification from the mobility condition determination unit, the multihoming controller transmits, to the MIP controller, an address (Addr2) consonant with the received HoA, and the MIP controller performs packet communication using the HoA or the CoA consonant with the address.

摘要： Disclosed is technique for avoiding packet reflection between home agents. According to the technique, a MN 10 includes a home address (HoA1) assigned thereto from a home network 12, and a home address (HoA2) assigned thereto from a home network 14. CoA is further acquired from a foreign network 15. Then, the MN uses the home addresses as care-of addresses, and performs binding-update including HoA1-HoA2 for the HA 12 and binding-update including HoA2-HoA1 as well as HoA2-CoA for the HA 14. A packet transmitted from a CN 16 to HoA1 is encapsulated by the HA 12 and transferred to the HA 14. The HA 14 refers to a source address of the received encapsulated packet and selects CoA as a transfer destination address instead of HoA2 having the same prefix.

摘要： The present invention provides a new technique, according to which a mobile router can fulfill functions as a dynamic home agent, in a system where a plurality of mobile routers are in operation, under the management of a service provider belonging to the home agent. According to this technique, the home agent verifies the legitimacy of the mobile router when it receives a Query message and a binding update message requesting permission to fulfill functions as dynamic home agent. Then, after confirming that no other mobile router is currently present, which is fulfilling the functions as dynamic home agent in a set of a plurality of mobile routers, to which this mobile router belongs, it allows said mobile router to operate as the dynamic home agent. Then, even when other mobile router requests the permission to fulfill functions as the dynamic home agent, the request is rejected, and said other mobile router utilizes the mobile router, which is fulfilling functions of the dynamic home agent, as its home agent.

摘要： The invention discloses a technique to efficiently realize a routing based on preference of a mobile terminal in case the mobile terminal is connected to a mobility management domain of network base different from a home network domain. According to this technique, a mobile terminal (mobile node; MN) 101 has two interfaces, and these interfaces are connected to a mobility management domain (local mobility domain) 11 under the condition that these interfaces are connected to MAG 111 and MAG 112 respectively. In case MN itself decides one of the interfaces to be used for a specific packet flow communication, a routing preference to instruct that the packet flow is to be sent on a routing via the interface is notified to MAG. When MAG notifies the routing preference to LMA (filtering agent) 110, filtering based on the routing preference is carried out.

摘要： A technology is disclosed for providing a packet transfer control method that can transmit a DU message to a specific CN or a specific flow to prompt a change in destination, while maintaining a transfer request to a CoA from a HA. In the technology, when a home agent receives a packet addressed to a mobile terminal from a predetermined communication terminal, the mobile terminal transmits a second message to the home agent, the second message including information required for the home agent to transmit a first message to the predetermined communication terminal. The first message states that a currently used address addressed to the mobile terminal cannot be used. The home agent generates the first message based on the information included in the second message and transmits the generated first message to the predetermined communication terminal.

摘要： A technique is disclosed whereby, while a MN (mobile node) is separated from a home network, the status available on a home network is obtained, and a communication path is optimized for a packet to be transmitted between the MN and a CN (correspondent node) via a HA (home agent). According to this technique, an HA 20 that manages a plurality of home addresses allocated to an MN 10 detects communication statuses of, for example, an ISP1 and an ISP2, and selects a home address that is designated, for a packet transfer to be performed from the MN, via the HA, to a CN 15, as a source address for the inner packet of an encapsulated packet to be transmitted from the MN to the HA. Since the MN designates this home address as the source address for the inner packet, a packet decapsulated and transferred by the HA is delivered to the CN via the ISP1 or the ISP2 in a superior communication status.
