    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: 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 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 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: 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: In order to verify if upper-level router information, or ULRI (information on the upper-level router with respect to a predetermined node) is valid, MN (Mobile Node) 220 associated to ULMR (Upper-Level Mobile Router) 210 acquires ULRI such as the address of ULMR (310), inserts ULRI into a BU (Binding Update) message, and sends it to HA (Home Agent) 235 (320). On receiving the BU message with ULRI, HA sends a BA (Binding Acknowledgement) message set to pass through the router that is specified in ULRI (330). If ULRI is valid, ULMR forwards the BA message to MN (340). If ULRI is not valid, ULMR discards the BA message.

    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 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: 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.
