    摘要: A technique disclosed enables a node having a plurality of interfaces to conduct connection of the plurality of interfaces simultaneously in a communication network domain. A mobile node having a plurality of interfaces connects one of the interfaces with a MAG (mobile access gateway) 11a to take part in a NetLMM domain 18 using a NetLMM protocol, and a LMA (local mobility anchor) 13 includes association information with the MAG 11a registered therein. When the mobile node connects another interface with another MAG 11b, the LMA receives a registration request for association information of this mobile node with the MAG 11b, and makes an inquiry to the already registered MAG 11a as to whether link with the mobile node is still valid or not. If the link is valid, the LMA keeps association information of the mobile node with both of the MAGs 11a and 11b.

    摘要: A mobility condition determination unit, provided in an MIP controller that manages moving of a communication node, obtains and examines various conditions that have occurred as the 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, a notification indicating that a set of the selected HoA and a CoA constitutes 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: There is provided a technique for reducing the number of messages handled in a Return Routability (RR) procedure for performing authentication between a mobile node (MN) and a peer communication node (CN). According to the technique, an MN 1 pairs two or more care-of addresses assigned respectively to one or more interfaces, and sends a CN 3 one or more first messages including a second care-of address by setting a first care-of address in each pair of care-of addresses as a source address. The CN 3 receives the one or more first messages, generates signature tokens for the first and second care-of addresses, and sends one or more second messages including the generated signature tokens to the second care-of address of the MN 2.

    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: A technique to optimize packet transfer in a network is disclosed. According to this technique, a mobile node (MN) 1000 having a plurality of interfaces transmits a filter rule where setting conditions are defined to each of MAG (motility access gateway) 1060 and MAG 1080 connected for the purpose of setting the packet received by each of the interfaces. MAG transfers the received filter rule to a local mobility anchor (LMA) 1010. After analyzing the filter rule, LMA specifies the network node where the filter rule should be reflected and updates the filter rule only to this specific network node. For instance, in case MN desires that a packet from CN 1090 is received via a path 1002, LMA manages that a packet destined to MN as transmitted from CN is to be transferred to MAG 1060 with respect to MAG 1020.

    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 reducing the number of encapsulations required when MAP forwards a packet to a mobile node which is layered within mobile networks, with mobile networks nested and multiple mobile routers chained behind MAP (Mobility Anchor Point). MAP 120 manages the binding information between RCoA and LCoA for each of lower-level nodes and grasps the prefixes of each of lower-level mobile routers, for example, the prefix of mobile network 104 of MR 140 or the prefix of mobile network 106 of MR 142. For example, MAP 120 informs MR 140 of the prefix of the mobile network 106 and the binding information between RCoA and LCoA. In this way, MR 140 can grasp a next forwarding destination of the packet transmitted from MAP 120 to MN 150, and the packet can be reached at MN 150 unless the packet is encapsulated multiple times.

    摘要: 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.

    摘要: A technique is disclosed, by which generation of redundant signaling caused by processing to establish route optimization can be suppressed. According to this technique, an overlay network is formed on a network, and an overlay network service of home agent is provided by a pHA (proxy home agent) 124. An MR (mobile router) 130 and a VMN (visiting mobile node) 140 connected to the mobile network are both subscribed in the overlay network service. In this case, when MR is going to perform optimization processing of a route to a home agent of VMN, pHA transmits change-HA messages 216 and 218 to notify VMN to change the home agent to the home agent of MR. When VMN changes the home agent to the home agent of MR, MR recognizes that processing of route optimization to the home agent of VMN is not needed.
