摘要： A terminal apparatus is provided that minimizes traffic congestion by reducing end-to-end delay and maximizes the bandwidth available in shared N-tree ALM nodes. In this terminal apparatus, an optimal stream path information table (204) stores N-tree session information for all nodes. A server forwarding table (202) stores bandwidth-fair ALM route information for all nodes in a specific N-tree session. An ALM forwarding table constructor (218) updates M-tree session information stored in an optimal stream path information table (204) using network metrics and heuristic rules stored in a heuristic rule database (206), executes ALM_N-tree algorithm using updated N-tree session information, and thereby generates bandwidth-fair ALM route information.

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 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： A mobile terminal apparatus includes a plurality of interfaces, each interface being capable of, when an associated access mechanism thereof is in an active state, obtaining a connection to a network using one of a home-address and a care-of-address. The home-address is assigned to the interface in advance, and the care-of-address is assigned to the interface while the interface is in a domain where the home-address is not available. An instructing section instructs a setup of a binding of a home-address of a first interface of the plurality of interfaces and one of a home-address and a care-of-address of a second interface. A setup section sets up the binding.

摘要： When a mobile host or mobile router in nested mobile network is roaming in a domain with multiple mobility anchor points, if the mobile host or mobile router in the nested mobile network tree path chooses different mobility anchor points to derive its regional care-of address, routing sub-optimality may occur. To overcome such routing sub-optimality, this invention presents two main methods. The first method is where the mobile router detects that a downstream node in its tree path has derived a regional care-of address from another mobility anchor point, and will make appropriate on-demand duplicate registration at the other mobility anchorpoint. The second method is such that the mobile router informs its own mobility anchor point of other mobility anchor point addresses, so that the mobile router's mobility anchor point will pass the location entries of the mobile router to the other mobility anchor points.

摘要： A technique is disclosed, according to which a mobile node, having a plurality of interfaces and performing communication according to flow information when an operator is performing communication based on the flow information as defined by a policy, can select an interface suitable for the flow and can perform communication. According to this technique, a mobile node (MN 10) having a plurality of interfaces has a list to indicate domain limited flows to be transmitted only within a specific network (a trusted network), and a list to indicate the trusted networks. When a certain interface performs handover, and in case there is a domain limited flow that uses the interface, it is decided whether the network of handover destination is a trusted network or not, and in case the network of the handover destination is not a trusted network, it is decided whether it is possible or not to transmit and receive the domain limited flow via another interface that is connected to the trusted network.

摘要： An access control method for a plurality of data communications networks is disclosed that enables a plurality of local nodes (101) to communicate with each other even if the connection between an intermediate node (103) and a global server (105) is momentarily lost. In this method, when the connection to the global server (105) breaks down, the intermediate node (103) temporarily grants access to the local nodes (101) instead of the global server (105) in accordance with a predetermined policy, thus allowing operation of local networks to function normally until connection to the global network (104) is resumed.

摘要： In a future scenario where end to end route optimization protocol such as the Access Router Option protocol and Hierarchical Mobility Management protocol are implemented in the visiting mobile nodes, mobile routers and the mobility anchor points, routing sub-optimality may occur when visiting mobile node that is nested is trying to communicate with the correspondent node. To overcome such routing sub-optimality arising in this heterogeneous protocol scenario, this invention presents a primary mechanism where the registration at the mobility anchor point is such that the local care-of address associated with visiting mobile node and local care-of addresses associated with upstream mobile routers of the visiting mobile node can be obtained using a single access router option protocol type of recursive tracing mechanism. Such tracing is achieved by embedding a different type of address in the access router option based binding registration at the mobility anchor point.

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.

More particularly, the present invention relates to attaining fast and efficient location management signaling by means of secure delegation of signaling rights to some trusted signaling proxy server in the fixed domain, which does the location management signaling for the mobile node as a signaling proxy for the mobile node.
