摘要： Disclosed is a technique for enabling a device that needs to send high priority and high bandwidth user plane traffic to send the user plane traffic even in the case where a group bandwidth has an upper limit in group-based communication. According to the technique, when an MTC device that is to send high priority and high bandwidth user plane traffic sends a service request to a network node (P-GW 213a), the network node allows use of a minimum bandwidth bearer in the case where the upper limit of the group bandwidth is exceeded. The MTC device sends a traffic sending request to an MTC server 214a via the bearer. The MTC server stops traffic of an appropriate other MTC device, to secure a bandwidth for the MTC device having the high priority and high bandwidth user plane traffic.

摘要： Disclosed is a technique for enabling a mobile terminal, which is capable of using a plurality of communication routes for communication with a correspondent node, to select an appropriate communication route to communicate with the correspondent node. According to the technique, the mobile terminal (UE/MN 313B) requests a predetermined network node (P-GW 317) to detect whether or not the correspondent node (CN 318B) exists in the same domain. The P-GW monitors a packet sent from the CN to the UE/MN and, when detecting the packet, determines whether or not the CN exists in the same domain. In the case of determining that the CN exists in the same domain, the P-GW reports information that the CN exists in the same domain, to the UE/MN. The UE/MN selects an interface used for communicating with the CN, based on the reported determination result.

摘要： Disclosed is a technique for minimizing the number of prefixes to be allocated to a mobile terminal when the mobile terminal having multiple access technologies moves within a mobility management domain of a local network. According to the technique, management is so performed that prefixes necessary for a mobile terminal (MN 100) to perform communication will be allocated to the MN, and a mobility management domain 110 maintains only the prefixes necessary for the MN to perform communication. For example, when the MN detects a state in which a prefix needs changing (step S120), it determines a state in which network prefixes necessary for the MN are allocated to the MN, and notifies the mobility management domain of prefix preference for achieving this state (step s150). The prefix preference includes a reduce request for unnecessary prefixes, a reuse request on another interface, a recycle request indicative of use at another MN, and the like.

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： Disclosed is a technique to eliminate wasted tunneling encapsulation processing during redirection of a packet. According to the technique, when a packet of a first connection passing through a LMA 111 and a MAG 121 using a first address of an interface 131 of a MN 130 is redirected to a second connection passing through a LMA 112 and a MAG 122 using a second address of an interface 132 of the MN 130, a redirection tunnel T1 is established between the LMA 111 and the LMA 112. When the MAG 122 knows the first address, the LMA 112 encapsulates a packet addressed to the first address that is redirected via the tunnel T to be addressed to the MAG 122 for transferring.

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： 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 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： 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.
