摘要： Disclosed is a technique which enables a communication node connected to a router made to advertise a plurality of prefixes to use an address including an appropriate prefix. According to this technique, an MR (Mobile Router) (10) multicasts, to a mobile PAN (31), a router advertisement message including a prefix (MNPNEMO) derived from a home network to which it pertains, a prefix (MNPAR) advertised from an AR (access router) (10a) and prefix choice information indicative of one of the prefixes to be selected on the basis of a function relative to the mobile PAN (31). A node (VN 20a, LN 20b) connected to the mobile PAN refers to the prefix choice information of the router advertisement message so as to select a prefix appropriate thereto for configuring its own global address.

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： 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： 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： 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.

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： A technology is disclosed for actualizing route optimization on a network base, even when privacy-sensitive information, such as a position of a mobile node, is not revealed between two different networks. In the technology, a pHA 124 functions as a proxy home agent of a MN 130. When the pHA 124 receives a packet transmitted from the MN 130 (such as a packet destined for a MN 230), the pHA 124 transmits a query message inquiring about a current position to a home network 200 of the MN 230. In response to the query, a HA 220 gives notification of an address of a proxy home agent (pHA 224) in an overlay network to which the MN 230 is subscribing that is present nearest to the pHA 124. As a result, the pHA 124 sends the packet destined for the MN 230 to the pHA 224, and the packet is transmitted via the overlay network to which the MN 230 is subscribing.

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). When a node 420 with Address A wants to send a packet to a node 450 with Address D, the node with Address A inserts a list of immediate addresses into the packet. The list includes a node 430 with Address B and a node 440 with Address C, and the destination address of the packet is set to a next hop destination Address B. The node with Address B receives the packet and swaps the destination address with Address C described in the list of immediate addresses. Similarly, the node with Address C processes the same swapping process, and then the packet reaches the node with Address D.
