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.
摘要翻译：移动节点（MN）发送（4）回显请求，以便在发送归属代理（HA）的（3）绑定更新（BU）之后，将源地址设置为新的地址（nCoA））。接收到（4）回波请求的nAR旨在向作为回显请求的源地址的nCoA发送回应应答。然而，此时，由于在nAR的相邻缓存中不存在关于nCoA的条目，所以nAR向MN发送（5）邻居请求（NS），并且生成nCoA的相邻高速缓存条目。之后，当绑定确认（BA）到达nAR时，由于存在nCoA的条目，所以（8）BA和数据包（9）到（11）到达（8））BA被传送到MN而不在nAR中缓冲，对应于在发送（7）回波应答时生成的nCoA的条目。

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.

摘要： A paging agent 30 according to the present invention receives a paging request packet from a mobile node, and then determines a paging area, in response to the packet. The paging agent 30 notifies the mobile node of the determined paging area and controls this paging area. When the paging agent 30 receives a data packet directed to the mobile node in a paging control mode, it holds the packet in a buffer 371 and starts forwarding the data packet thus held, as triggered by reception of a paging notification confirmation packet from the mobile node.

摘要： A packet transmission control apparatus has a packet accumulating unit for buffering a plurality of packets. The apparatus further includes a transmission unit for and for transmitting, to a destination node, a front packet included in the plurality of packets buffered in the packet accumulating unit and for transmitting the remaining packets included in the plurality of packets to the destination node after a lapse of a time period starting from a time point of transmission of the front packet. The time period is equal or greater than a sum of predetermined downstream front packet processing time periods, the sum corresponding to a number of nodes the front packet passes through before reaching the destination node.
