摘要： A technology is disclosed for reducing the number of encapsulations required when MAP forwards a packet to a mobile node which is layered within mobile networks, with mobile networks nested and multiple mobile routers chained behind MAP (Mobility Anchor Point). When a node 420 with Address A wants to send a packet to a node 450 with Address D, the node with Address A inserts a list of immediate addresses into the packet. The list includes a node 430 with Address B and a node 440 with Address C, and the destination address of the packet is set to a next hop destination Address B. The node with Address B receives the packet and swaps the destination address with Address C described in the list of immediate addresses. Similarly, the node with Address C processes the same swapping process, and then the packet reaches the node with Address D.

摘要： Disclosed is a technique whereby a packet transferring apparatus (particularly, a tunnel entry point made to carry out packet encapsulation) becomes capable of detecting a tunneling loop signifying that a packet loops along the same route while undergoing encapsulation. With this technique, at packet transfer, a loop detection module of a router according to the present invention stores a TEL value (value of tunnel encapsulation limit for limiting the number of times of duplication of tunnel) set in an encapsulation header of this packet or stores a TEL value set in an encapsulation header of a packet sent back as an ICMP error In addition, the loop detection module analyzes an increase/decrease variation pattern of the stored TEL value relative to time and, in a case in which the pattern agrees with a unique pattern (sawtooth-like pattern) appearing at the occurrence of a tunneling loop, estimates that a tunneling loop has occurred.

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： A technology is disclosed for efficiently and effectively conveying location and mobility related information about a mobile node to the network in order to facilitate Location and mobility related functions and services. According to this technology, in order to detect location and mobility (for example, movement velocity) of the mobile node, dissemination of information including the identification information of the mobile node and the count metric indicating the distance to the mobile node is performed among adjacent network nodes. The network node, upon receiving this message, stores the information in the message, and generates a new count metric by decreasing the count metric. The network node then sends the message including the identification information of the mobile node and this newly generated count metric to the other network nodes. For example the network node determines the priority of resource reservation for each mobile node based on the count metric of each mobile node.

摘要： According to the present invention, connection can be always maintained between the mobile node and the access router, and disruption of on-going transport session can be prevented by making effective use of two architectures (hierarchical and mesh architectures). The mobile nodes 1000-1, 1000-2 and 1000-3 are attached to the access router 1100-1. When the mobile node maintains link layer connectivity with the access router, it is in the hierarchical mode, whereas when the link layer connectivity is lost, it enters the mesh mode. In the mesh mode, the mobile node attempts to establish virtual link layer connectivity with the access router through other nodes by using mesh network protocol such as MANET. In the mesh mode, the packet is capsulated between the mobile node and the access router when the mobile node and the peer 1400-1 communicate with each other.

摘要： The present invention introduces a method for the network to optimize the route for user's local IP access, without affecting the access to operator's core network. With this mechanism, no excessive signalling is needed for the optimization. The present invention is also applicable to the corporate network that has multiple home NodeBs or home eNodeBs. Finer grain control on the services to be provided over different home NodeB or home eNodeB is also possible. Further, path optimization and continuation of the service upon handover can be controlled, and hence flexibility of the service can be secured.

摘要： A technique is disclosed, according to which a race condition between a PMIPv6 binding by a PBU message of PMIPv6 and a CMIPv6 binding by a BU message of CMIPv6 can be resolved. MN 200 has a plurality of radio communication interfaces, and a first interface is connected to MAG 220 of a home PMIPv6 domain 230, for instance. In case the connection of a second interface is changed from MAG 221 of a home PMIPv6 domain to AR 222 of a CMIPv6 domain 231, a BU message 262 is transmitted from the second interface to LMA/HA 250, and identification information of this BU message is notified to MAG from the first interface. By adding time information to this identification information and by transmitting it to LMA/HA, MAG can identify transmission time of the BU message (i.e. relative order with the other messages) from this time information.

摘要： Disclosed is a technique for surely supporting multihoming for a mobile terminal (mobile node) moving in a local mobility domain. A mobile node (MN) 11 connects via an IF 110 to a mobile access gateway (MAG) 102 that supports multihoming, and further attempts to connect via an IF 111 to a MAG 103 that does not support multihoming. Under these conditions, according to this technique, when the MN recognizes that the MAG 103 does not support multihoming, the MN notifies a local mobility domain that the MAG 103 does not support multihoming if connection with the MAG 103 is not yet established, and notifies the local mobility domain of information on a connection to a local mobility domain other than the MAG 103 (connection with the MAG 102) if the connection with the MAG 103 is already established.

摘要： With the deployment of home NodeB or home eNodeB, a user can access both operator's core network and Local IP Access (LIPA), e.g. to home based network or general Internet, on the same device at the same time. However, existing mechanisms does not allow an efficient way of LIPA mobility support, especially when there are multiple home NodeBs or home eNodeBs serving the same LIPA domain. The present invention provides a solution that can achieve seamless mobility among different home NodeBs or home eNodeBs without interruption to LIPA service. The LIPA traffic for the terminal can be contained within the local domain during the handover process. It also provides support of the relocation of the gateway that provides the LIPA access to the mobile terminal.
