摘要： A home gateway device having a home agent function selects communication interfaces other than the communication interface which has acquired network information for setting a home network to be home links, and appropriately sets the home link and a home agent by using the acquired network information, thereby reliably achieving the automatization of the device setting. Moreover, the home gateway device selects a link connected to a mobile terminal based on a mobile IP as home link, acquires existing home agent information from the mobile terminal and makes settings with this information, thereby setting the home link without compelling the mobile terminal to change its setting.

摘要： The invention relates to optimizing a data path between two communication nodes. A route optimization agent (ROA) is determined in the current network of the second communication node, preferably on the data path between the two communication nodes. Then, an IP tunnel is established between the first communication node and the ROA, the IP tunnel and the corresponding security association of said IP tunnel being based on the home address of the first communication node in its home network. The first communication node may have two IP tunnels based on the same home address, one to its home agent and one to the ROA. Corresponding routing entries and binding cache entries need to be established in the ROA and the first communication node so that all data packets between the two communication nodes are exchanged via the established IP tunnel over the ROA.

摘要： The invention relates to a method, mobile node and computer-readable medium for establishing (or pre-establishing) a secure tunnel to an ePDG to prepare for a mobile node attachment or handover to another access network. To reduce the delay of a handover or upon attachment of a mobile node to an access network implied by mechanisms to discover a ePDG, the mobile node maintains a reachability list that can be consulted to identify an ePDG or ePDGs that are reachable in the target access network, i.e. to which the mobile node may establish a secure tunnel. If the mobile node can identify a reachable ePDG for a given access network from the reachability list, the mobile node (pre-)establishes a secure tunnel to the ePDG upon attaching to the given access network. In alternative solutions DNS, DHCP or other mechanism can be used to provide the mobile node with information on ePDGs in its vicinity.

摘要： A technology is disclosed that provides a handover method and the like capable of improving communication efficiency by detecting that a handover destination network is a home link at an early stage and reducing tunnel overhead between a mobile node and a home agent. The technology includes, when the mobile node performs a handover from an access router of a network before the handover to which the mobile node is currently connected, to an access router of another network that is a handover destination: a step of transmitting, by a mobile node 107, an address allocation request message for acquiring an address in the handover destination network allocated to the mobile node, to the access router of the handover destination; and a step of transmitting, by a home agent 106 of the mobile node, a notification message including information indicating a type of the address of the mobile node allocated by an address allocation server of the handover destination or the home agent as a result of the address allocation request message, to the mobile node via the access router before the handover.

摘要： A router, if judging that a routing function is impossible to execute, sends out a connection instruction message including the address of a terminal on a local network terminating the relaying flow, to another router to solicit switching. The router having received the connection instruction message starts a process for connecting with an external network while executing a process for link connection with a terminal, and then sends out a connection completion notice message when the connection with both the external network and the terminal is established. This process enables the router to switch a path rapidly.

摘要： In a mobile communication system using a mobile IP, a mobile terminal determines a main home agent and a main home address. When the mobile terminal moved to a network different in service form, a home address for use on a moved-in domain network is registered as a primary care of address to the main home agent, thereby enabling communications by using the main home address even upon accessed from the other than the belonging domain network. This makes it possible to flexibly cope with an incoming call from the external by the use of a representative home address even on the Internet as a distributed network.

摘要： A router device includes a VRRP (Virtual Redundancy Router Protocol) realizing a virtual router device for operating a plurality of router devices virtually as one router device. The router device further includes a virtual router processing section for executing virtual router processing and a virtual router information processing section for extracting virtual router information upon reception of a virtual router information message and performing setting necessary for operation as a virtual router. When performing a new connection to a local area network, the virtual router information can be automatically set. Thus, it is possible to significantly reduce the load required for building a virtual router system by manual setting conventionally performed by a management operator.
