摘要： For communications between several different types of wireless networks and a mobile node, technology to provide various services from a wireless network to the mobile node which is not covered by that network without exhaustion of the mobile node battery is disclosed. According to this technology, the mobile node sends an update message to a currently accessible network node, which transfers the update message to the same or different types of nearby network nodes with incrementing the hop count for every transfer. The different type of network node that has received the update message checks whether the hop count decreases from that previously received and judges that the mobile node is approaching if the hop count decreases and sends the guide message to the mobile node via the same and different types of networks.

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： 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： 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.
