摘要： The present invention provides a packet communication system including a mobile host, a home agent, a correspondent host, and a mobility agent, where the mobility agent operates in such a way that when the mobile host is in an active mode and has no need for buffering packets, the mobility agent forwards packets received from the home agent or the correspondent host to the mobile host; and alternatively, in the case when the mobile host is in an active mode, but requires buffering of packets, the mobility agent buffers the packets, and further in the case when the mobile host is in an idle mode, the mobility agent buffers the packet and notifies the mobile host of arrival of the packet, in order to prevent the loss of a packet addressed to a mobile host thus decreasing the traffic and the transmission frequency of Binding Update packets.

摘要： A packet transmission system includes a home agent providing a home link and a home address to a mobile node, one or more access routers, each providing a foreign link and a c/o address to the mobile node, and one or more mobility support routers that relay a packet to the destination between the mobile node and the home agent or a counterpart correspondent node. When the mobile node moves into a new foreign link, the corresponding access router transmits a registration request to the home agent and/or the correspondent node. When acquiring a registration request on the way to the destination, each mobility support router stores an entry having the home address of the mobile node and the c/o address contained in the registration request, and produces and transmits a new registration request updating the c/o address to its own address. When receiving a packet addressed to the home address recorded in the entry, the mobility support router encapsulates this packet to produce a tunneling packet and relays the tunneling packet to the c/o address that is recorded in the entry in association with the home address, thereby correctly forwarding the data packet to the destination.

摘要： Provided is a mobility management node capable of forming a paging area, without need for management of a migration history at a mobile node and for notification of a migration history from a mobile node to a network. In mobility management node (MAP) 1, mobility manager 66 lets binding cache 68 store a home address and a c/o address of each mobile node (MN) in correlation with each other. Migration history storage 70 stores a transition frequency of the c/o address stored in binding cache 68 in correlation with prefixes before and after transition. Migration history storage 70 defines paging area information by a set of prefixes included in combinations containing common prefixes, out of combinations of prefixes before and after transition with each of which a transition frequency over a predetermined reference value is correlated. Paging controller 72 notifies the MN of this paging area information.

摘要： A mobile node (MN) transmits a (4) echo request to the effect that the source address is set to be a new care of address (nCoA) right after transmitting a (3) binding update (BU) for a home agent (HA). The nAR having received the (4) echo request intends to transmit an echo reply to the nCoA being the source address of the echo request. However, at this time, since an entry regarding the nCoA does not exist in a neighbor cache of the nAR, the nAR transmits (5) neighbor solicitation (NS) to the MN, and generates a neighbor cache entry of the nCoA. After this, at the time when a binding acknowledgment (BA) has arrived at the nAR, since the entry of the nCoA exists, the (8) BA and data packets (9) to (11) arriving at the nAR following the (8) BA are transferred to the MN without buffering in the nAR, corresponding to the entry of the nCoA generated at the time of transmission of the (7) echo reply.

摘要： When a mobile node MN moves from an access router AR3 to another access router AR4, it sends a multi-binding on request to a mobility agent MA1 and then moves ({circle around (1)}). Receiving the multi-binding on request, the mobility agent MA1 voluntarily configures prospective CoA's (probable CoA's) The probable CoA's are added as forwarding addresses while an M bit is set on in an register of the mobile node MN on a binding cache ({circle around (2)}). When the mobility agent MA1 receives a capsuled packet addressed to the mobile node MN thereafter, it tunnel-forwards the packet to CoA3, probable CoA2, and probable CoA4 according to the binding cache ({circle around (3)}).

摘要： An object of the present invention is to decrease a care-of address update duration in switching of a link used for connection to an IP network by a mobile node (MN). MN acquires a list of access routers (ARs) existing on neighboring links to the link used for connection by the mobile node and creates a list of care-of addresses (CoAs) corresponding to the respective ARs entered in the list, each CoA being used as a destination of MN at a link on which an AR corresponding thereto exists. After the change of the connected link, MN acquires a data link layer address of AR existing on the link after the change and detects a default router on the basis of the address with reference to the access node list. Furthermore, MN detects a CoA with a network prefix corresponding with a subnet prefix of the default router, as a primary CoA and requests MAP to register a binding between the primary CoA and HoA.
