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： There is disclosed a technique which can detect a packet routing loop (in particular, a nesting loop formed by MRs (mobile routers). According to this technique, an MR 114 connected as a subordinate to an MR 110 transmits a BU (Binding Update) message, to which added is an ARO (Access Router Option) including an address of a router (MR 110) connected at present, to an HA (Home Agent) 140 to which it pertains. Moreover, an MR 112 is connected as a subordinate to the MR 114 and, when connected to the MR 112, the MR 110 transmits a BU message, to which added is an ARO including an address of the MR 112, to the HA 140. At this time, the MR 112 also transmits a BU message, to which added is an ARO including an address of the MR 114, to the HA 140. Thus, the HA 140 can detect a routing loop formed by connections 120, 122 and 124.

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： Disclosed is a technique for switching a forwarding address of a packet destined for a mobile node in a local mobility domain when the mobile node has a plurality of interfaces so that the packet will be forwarded to the mobile node. According to the technique, an MN 101 receives network information 40 including a domain ID 402 from a network through two or more IFs 1010 and 1011. Based on the domain ID 402 in the network information received, when determining that the IFs 1010 and 1011 are attached to the same domain, the MN 101 decides to allocate the same address to the IFs 1010 and 1011, and requests MAGs 111 and 112 connected to the IFs 1010 and 1011, respectively, to bind the same address to each of link identifiers of the IFs 1010 and 1011. Based on the request, the MAGs 111 and 112 perform binding to forward, to the MN 101, packets destined to the same address of the MN 101.

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： Disclosed is a technique that, in a network-based local mobility management method, reduces the load of a network node for managing position information of a mobile terminal and achieves a high scalability with respect to the number of mobile terminals. According to the technique, a LMA (Local Mobility Anchor) (1000) assigns a primary network prefix to each of MAGs (Mobility Access Gateways) (1010, 1020) under the control of the LMA and registers, in a routing table, the correspondence relationship between the position information of each of the MAGs and the primary network prefix assigned to each of the MAGs. In addition, among MNs (MobileNodes) (1030, 1040) connected under the MAGs, for a MN that uses an address including a secondary network prefix, the LMA registers, in a binding cache, the correspondence relationship between the MN and the position information of an MAG to which the MN is connected.

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.
