摘要： A technology is disclosed with which a mobile terminal moving in a PMIP domain receives various types of prefixes and selects a type of an address to be configured, and route optimization is performed without adding a signaling load on the PMIP domain. According to the technique, when connecting with a home domain, a MN (310) requests a plurality of prefixes. When a MAG (320) makes an AAA server (340) authorize the MN and receives a notification instruction of the plurality of prefixes from the AAA server, the MAG 320 makes a notification of the plurality of prefixes with a RA message (364), for example. The MN configures a plurality of addresses (for example, a PMIP address including a PMIP domain prefix or a global address including an on-link prefix) from the plurality of prefixes received and notifies the MAG of the same. The MAG registers a plurality of bindings relating to the plurality of addresses with a LMA (330).

摘要： The present invention provides a technique to prevent the generation of a large number of binding update messages in an overlay network when a mobile node changes connection points. According to this technique, in a communication system where a home agent HA 1210 for holding BCE (Binding Cache Entry) of a mobile node MN 1220 and a plurality of proxy home agents pHA 1212, pHA 1214 and pHA 1216 each capable to operate as a proxy of HA 1210 are overlaid on a global communication network 1200, and BCE of MN 1220 held by HA 1210 is delegated to pHA 1214 where MN 1220 is connected. Further, when MN 1220 is re-connected to pHA 1216 of move destination different from pHA 114 of move source, BCE of MN 1220 delegated to pHA 1214 of move source is re-delegated to pHA 1216 of move destination.

摘要： A technique is disclosed to decrease unnecessary routing during communication between a mobile node and a correspondent node in case a home agent of the mobile node is a mobile home agent. According to this technique, HA 112 positioned in a home network 102 and HA 114 of MN 130 are included. In a communication system, where HA 114 is a mobile home agent, and a mobile network 104 of HA 114 is hierarchized under the home network 102, HA 114, which is a home agent, discovers HA 112 positioned in the home network 102 when it is detected that it is away from the home network 102 and delegates binding cache entry of MN 130 under its own management to HA 112 so that HA 112 acts as a home agent for MN 130.

摘要： Disclosed is a technique to prevent the registration of false information that a mobile router is managing prefix information that is not actually managed. According to the technique, when a mobile network prefix is registered from an MR (mobile router 20) to a CN 30 (correspondent node), an HA (home agent) 10, for example, intervenes in signaling related to the registration to prevent the registration of false prefix information. For example, in process 150, the MR notifies the prefix information and the HA detects a test message 120 sent from the CN to the MR to check whether the prefix information used for the destination address is valid. If the prefix information is invalid, the packet is discarded.

摘要： The present invention provides a technique to optimize communication route when two end nodes separated away from own home perform data communication with each other. According to this technique, a communication node (the initiator node 174) adds a predetermined destination option including own home address to a header of a packet to be transmitted to a correspondent node (LFN 151) under control of MR 141. HA 121 of MR copies a predetermined destination option and inserts it into a tunnel packet header when this packet is tunneled to MR. When the packet is transferred to the communication node under control, MR checks, by using the server, whether the predetermined destination option is inserted into the tunnel packet header or not. If it is inserted into the packet, a route optimization processing is started with the transmitter of the packet including the predetermined destination option with home address.

摘要： A technology is disclosed for reducing the burst of DAD messages which may be triggered due to the change of the network prefix when using the technique of the neighbor discovery proxy. According to this technology, in roaming from the access network link 101 to the access network link 102, MR 121 receives advertisement of a new prefix 172 from AR 112. MR 121 selects and informs, for example only MR 122, that it is necessary to change the prefix. Thus, MR 122 and VMN 132 configure new addresses, respectively. When address configuration is completed at the mobile network of MR 122, MR 121 informs another MR 123 that it is necessary to change the prefix, and then MR 123 and VMN 133 configure new addresses, respectively. This can prevent DAD messages generated along with the address configuration from flocking in a short period.

摘要： To overcome the routing sub-optimality problem arising in the heterogeneous protocol scenario where end-to-end route optimization protocol such as the Access Router Option protocol and Hierarchical Mobility Management protocol are implemented in the mobile hosts and mobile routers, this invention presents three methods. The first method is such that when visiting mobile node or mobile router wants to perform access router option based route optimization with some node, it will use its local care-of address as its care-of address. The second method is such that when visiting mobile node or mobile router decides to use hierarchical mobility management with some node, it will use regional care-of address as its care-of address. The third method is such that when there is legacy mobility anchor point in architecture, mobile router does not send the mobility anchor point option in its router advertisement.

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.
