摘要： A technology is disclosed for a mobile device with multiple interfaces to make use of its multiple interfaces capability with Mobile IP. According to this technology, MN (Mobile Node) 100 comprises a cellular interface to connect to the cellular network 112 and a Wireless-LAN interface to connect to the local network 122 and 132, and sends a Binding Update message to set the address of the Wireless-LAN interface to CoA (Care-of Address) to HA (Home Agent) at the cellular network or CN (Correspondent Node) 160. This Binding Update message includes a special label indication that the cellular interface is currently connected to the home network.

摘要： A technology is disclosed for certainly performing dynamic routing and error checking processes in the mobile network. According to this technology, the home agent sets up a Binding Acknowledgement message with a smaller Lifetime value when receiving a Binding Update message from a mobile router. During this smaller Lifetime, the mobile router can send a Routing Update message to the home agent. Thus, the home agent, for example, can check consistency of prefix information specified in the Biding Update with route installed by the Routing Update message. The present invention can be applied to both two distinct modes (explicit mode and implicit mode) that prefix information is specified in the Binding Update or not.

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： 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.

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： Disclosed is a technique whereby a tunnel entry point, which encapsulates a packet (generates a tunnel packet), can detect the presence of a tunneling loop causing a packet to loop the same path while encapsulated. According to this technique, upon receipt of a packet from a source node (source) 1100, TEP (tunnel entry point) 1120 inserts it into a tunnel packet header for encapsulation. Upon receipt of tunnel packets from TEP 1120 and TEP 1140, each of TEP 1140 and TEP 1160 copies the identifier of the original tunnel packet header to a new tunnel packet header for encapsulation. When this tunnel packet returns to TEP 1120 due to a tunneling loop, the tunneling loop is detected by referring to the identifier in the received tunnel packet.

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 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 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.
