    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 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。
