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： A mobility condition determination unit, provided in an MIP controller that manages moving of a communication node, obtains and examines various conditions that have occurred as the 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, a notification indicating that a set of the selected HoA and a CoA constitutes 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： 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： The present invention provides a new technique, according to which a mobile router can fulfill functions as a dynamic home agent, in a system where a plurality of mobile routers are in operation, under the management of a service provider belonging to the home agent. According to this technique, the home agent verifies the legitimacy of the mobile router when it receives a Query message and a binding update message requesting permission to fulfill functions as dynamic home agent. Then, after confirming that no other mobile router is currently present, which is fulfilling the functions as dynamic home agent in a set of a plurality of mobile routers, to which this mobile router belongs, it allows said mobile router to operate as the dynamic home agent. Then, even when other mobile router requests the permission to fulfill functions as the dynamic home agent, the request is rejected, and said other mobile router utilizes the mobile router, which is fulfilling functions of the dynamic home agent, as its home agent.

摘要： A technique to optimize packet transfer in a network is disclosed. According to this technique, a mobile node (MN) 1000 having a plurality of interfaces transmits a filter rule where setting conditions are defined to each of MAG (motility access gateway) 1060 and MAG 1080 connected for the purpose of setting the packet received by each of the interfaces. MAG transfers the received filter rule to a local mobility anchor (LMA) 1010. After analyzing the filter rule, LMA specifies the network node where the filter rule should be reflected and updates the filter rule only to this specific network node. For instance, in case MN desires that a packet from CN 1090 is received via a path 1002, LMA manages that a packet destined to MN as transmitted from CN is to be transferred to MAG 1060 with respect to MAG 1020.
摘要翻译：公开了一种优化网络中的分组传输的技术。根据该技术，具有多个接口的移动节点（MN）1000发送滤波器规则，其中设置条件被定义为MAG（运动接入网关）1060和MAG 1080连接的每一个，用于设置由每个接收的分组接收的分组的接口。 MAG将接收到的过滤规则传送到本地移动锚点（LMA）1010.在分析过滤规则之后，LMA指定应反映过滤规则的网络节点，并将过滤规则更新到该特定网络节点。例如，在MN希望经由路径1002接收到来自CN 1090的分组的情况下，LMA管理将从CN发送的去往MN的分组相对于MAG 1020传送到MAG 1060。

摘要： The invention discloses a technique to efficiently realize a routing based on preference of a mobile terminal in case the mobile terminal is connected to a mobility management domain of network base different from a home network domain. According to this technique, a mobile terminal (mobile node; MN) 101 has two interfaces, and these interfaces are connected to a mobility management domain (local mobility domain) 11 under the condition that these interfaces are connected to MAG 111 and MAG 112 respectively. In case MN itself decides one of the interfaces to be used for a specific packet flow communication, a routing preference to instruct that the packet flow is to be sent on a routing via the interface is notified to MAG. When MAG notifies the routing preference to LMA (filtering agent) 110, filtering based on the routing preference is carried out.

摘要： Disclosed is a technique to prevent the registration of false information that a mobile router is managing prefix information that is not actually managed. According to the technique, when a mobile network prefix is registered from an MR (mobile router 20) to a CN 30 (correspondent node), an HA (home agent) 10, for example, intervenes in signaling related to the registration to prevent the registration of false prefix information. For example, in process 150, the MR notifies the prefix information and the HA detects a test message 120 sent from the CN to the MR to check whether the prefix information used for the destination address is valid. If the prefix information is invalid, the packet is discarded.

摘要： Disclosed in a technique for more accurately checking a network condition such as a transmission delay generated in packet transmission between two nodes and other network conditions. A buffering node 10 is a network node having the function of transferring a packet. When a packet received by a network interface 11 is buffered in a cache 14, a buffer time processor 12 refers to an internal clock 13 to record the time of that moment (the buffered time). Then, when this packet is transferred, the buffer time processor refers again to the current time indicated by the internal clock and subtracts the buffered time from the current time to calculate a buffering time generated by a buffering delay in packet transmission. This buffering time is added to the packet and transmitted.

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.
