    摘要: The invention relates to a method for discovering a home agent serving a mobile node upon the mobile node changing its mobility management scheme in a packet-switched network and the implementation of such method in a mobile node or home agent. In order to propose a home agent discover scheme that maintains session continuity in a seamless manner upon a mobile node changing its mobility management scheme, a mobile node comprises information on its location prior to changing the mobility management scheme to one of the first signaling messages transmitted upon changing the mobility management scheme (home agent discovery message). The receiving node uses this information to identify the home agent serving the mobile node or to provide a hint to the home agent where the mobile node is registered in a response message to the mobile node. This approach may also be used for path optimization when a mobile node moves from a trusted to an un-trusted access network.

    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: The invention discloses a technique, by which the number of messages can be decreased when RR (Return Routability) procedure is performed to give authentication between a mobile node (MN) and a correspondent node (CN). According to this technique, CN 3 receives a plurality of CoTi messages transmitted from each of a plurality of interfaces of MN 1, generates a signature token for each of a plurality of care-of addresses, and transmits the signature token in each of a plurality of CoT messages to MN. Then, MN generates a common key for a plurality of care-of addresses by using each signature token of said plurality of CoT messages, generates a common authentication code for said plurality of care-of addresses by using said common key, transmits a bulk binding update message containing said plurality of care-of addresses and the common authentication code to CN. CN authenticates the common authentication code for said plurality of care-of addresses in the bulk binding update message. Also, CoTi and CoT are transmitted in a bulk message, and BU messages are transmitted individually to each CoA.

    摘要: Disclosed is a technique of efficiently collecting communication quality information with excellent responsiveness in wireless resource management. According to the technique, a RRM 110 distributes measurement content information showing measurement contents for recognizing a wireless communication status to each AP 230, and each AP stores the measurement content information. For example, to recognize a wireless resource use status of an AP, the RRM transmits trigger transmission instruction information to an eNB 150, as a result of which trigger information is transmitted throughout a communication area of the eNB. A UE 301 that has received the trigger information acquires the measurement content information from an AP (for example, AP_a 230a) to which it is connected, and performs a measurement process and reports a measurement result to the RRM via the eNB based on the measurement content information.

    摘要: A technique is disclosed of, when a mobile node has moved outside of a domain using a local address, enabling an old path of the mobile node in the domain to be torn down without using special means such as a STUN server. According to this technique, a MN 101 and a SANE 103 register a group to a group server 201 using a group registration request message 3001 and a group join request message 3007, respectively. When the MN 101 moves to a new location (MN 110) outside of a NAT domain 100, the MN 110 transmits a MN trigger message 3011 to the group server 201. Receiving the MN trigger message 3011 from the MN 110, the group server 201 transmits a group trigger message 3013 to all SANEs 103 in a group member list. Receiving the group trigger message 3013, the SANEs 103 tear down a state of an old path of the MN 101 before movement and release a resource thereof.

    摘要: Disclosed is a technique in which, when a plurality of packet routing paths exist, a sender of the packet selects an optimum packet length so as to use network resources effectively. According to the technique, when a plurality of routing paths like a network A (104) and a network B (105) exist for a packet transmitted from a data transmitting apparatus (103) to a data receiving apparatus (102) via a network relay apparatus (101), the network relay apparatus or the data receiving apparatus searches path MTU information of each path, and notifies the data transmitting apparatus of multipath MTU information including each search result. The data transmitting apparatus refers to this multipath MTU information to compare the plurality of paths about their path MTU information to decide a packet length suitable for the packet transmitted to the data receiving apparatus.
