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： 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 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 technique is disclosed, according to which a race condition between a PMIPv6 binding by a PBU message of PMIPv6 and a CMIPv6 binding by a BU message of CMIPv6 can be resolved. MN 200 has a plurality of radio communication interfaces, and a first interface is connected to MAG 220 of a home PMIPv6 domain 230, for instance. In case the connection of a second interface is changed from MAG 221 of a home PMIPv6 domain to AR 222 of a CMIPv6 domain 231, a BU message 262 is transmitted from the second interface to LMA/HA 250, and identification information of this BU message is notified to MAG from the first interface. By adding time information to this identification information and by transmitting it to LMA/HA, MAG can identify transmission time of the BU message (i.e. relative order with the other messages) from this time information.

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.
