摘要： Disclosed is a technique which reduces or omits the time needed for DAD processing solicited when a mobile communication device establishes a connection with a new subnetwork, thereby reducing the packet loss and delay to improve the communication efficiency. According to this technique, in a network in which a plurality of ARs 11 to 14 exist, when a mobile communication device (MN 10) establishes a connection with one of these plurality of ARs, in addition to the implementation of the DAD processing for confirming whether or not the address (CoA) of the MN is usable at the connection-accepting side, a wide-range DAD implementation request message including the interface ID of the MN is transmitted from the connection-accepting side AR to the other AR existing in a network of a given range (wide-range DAD effective area 31), and in a subnetwork under each of ARs, the DAD processing is conducted so as to confirm whether or not the address at the connection of the MN is usable. This enables the DAD processing to be omitted when the MN moves to the other subnetwork.

摘要： Disclosed is a technique for achieving reduction in processing load caused when a mobile terminal having two or more interfaces registers flow control information with a network and reduction in traffic of signaling for the registration. According to this technique, a mobile terminal (MN100) has two or more interfaces (IF1 and IF2), registers, with a home agent (HA200), binding information between care-of addresses (CoA1 and CoA2) assigned to each interface and a home address (HoA0) of the MN, and further acquires home addresses (HoA1 and HoA2) exclusively for each interface and to be set for the interface and registers, with the HA, binding information between the HoA exclusively for each interface and a CoA corresponding to the HoA. For a flow desired to be sent and received by using only a specific interface, the HoA and CoA exclusively for the interface are used.

摘要： A technique is disclosed whereby, while a MN (mobile node) is separated from a home network, the status available on a home network is obtained, and a communication path is optimized for a packet to be transmitted between the MN and a CN (correspondent node) via a HA (home agent). According to this technique, an HA 20 that manages a plurality of home addresses allocated to an MN 10 detects communication statuses of, for example, an ISP1 and an ISP2, and selects a home address that is designated, for a packet transfer to be performed from the MN, via the HA, to a CN 15, as a source address for the inner packet of an encapsulated packet to be transmitted from the MN to the HA. Since the MN designates this home address as the source address for the inner packet, a packet decapsulated and transferred by the HA is delivered to the CN via the ISP1 or the ISP2 in a superior communication status.

摘要： Disclosed is a technique which, when an MN (mobile node) has one or a plurality of HoAs (home addresses) and a packet is transmitted from a CN (correspondent node) through an HA (home agent) to the MN, reduces a delay stemming from registration processing on binding information or selection processing among the plurality of HoAs and a delay of communication due to a result of the selection. According to this technique, an MN 100 notifies, to the CN, home network connection information indicative of whether or not it is currently in connection with a home network which has allocated its own plurality of HoAs, an address of each HA and an ID of each HA in a state associated with the plurality of HoAs. On the basis of the information received from the MN, an CN 150 grasps the home network with which the MN is currently in connection and makes an inquiry about the condition of the HA and sets an appropriate HoA, judged on the basis of the grasping result or the inquiry result, as a destination address of a packet to be transmitted to the MN.

摘要： Disclosed is a technique capable of proper execution of access control based on various security policies set by a home user with regards to a packet sent from a visitor node. According to the technique, a MR (Mobile Router) 10 which manages a mobile PAN 30 determines whether a sender of a packet from a communication terminal connected to the mobile PAN is a home user's node which is allowed direct access into a home network or a visitor node (VN 31), and forwards the packet from the home user's node to an HA 20 while forwarding the packet from the visitor node to a policy server 36 located in a DMZ 35. This allows the policy server to perform access control on every packet from a visitor node which attempts to gain access into the home network based on a security policy 36a.

摘要： Disclosed is a technique which enables a mobile node (MN) connected to a mobile router (MR) to carry out flow filtering in a mobile network. This technique allows an MN 25 in a mobile network 24 to set a policy needed for the flow filtering in an MR 10 and, in the present invention, an MR inserts an egress characteristic thereof into, for example, a router advertisement message so that the egress characteristic, a node in a mobile network cannot grasp originally, can be advertised to the interior of the mobile network. Thus, the MN can grasp a characteristic of an access network (characteristic of access system 20) even in a case in which it is connected to the MR, which achieves intelligent flow filtering.

摘要： Disclosed is a technique for allowing a mobility service provider to allocate a home agent appropriate for each individual mobile node. According to the technique, an MN 10 notifies the domain name of an MSP 3 to an ASP 1, and in response to the notified domain name of the MSP, the ASP notifies the address of an HA allocation server 3a to the MN. The MN transmits, to the notified address of the HA allocation server, an HA allocation request message including the domain name of the ASP. The HA allocation server selects an HA based on previously held correspondences between HAs 3b, 3c and one or more ASPs, and notifies the selected HA to the MN.
