Patent ID: 8879504

Claim:
A redirection system for redirecting a packet from a first connection of a mobile node to a second connection of the mobile node, the first connection passing through a first home agent and a first proxy node using a first prefix assigned to a first interface of the mobile node, the second connection passing through a second home agent and a second proxy node using a second prefix assigned to a second interface of the mobile node, comprising: means that establishes a tunnel for redirection between the first home agent and the second home agent and makes the first home agent encapsulate the packet addressed to the first prefix to be addressed to the second home agent on a basis of a redirection request and redirect the packet via the tunnel for redirection; means that, when the second proxy node knows the first prefix, makes the second home agent encapsulate the packet addressed to the first prefix that is redirected via the tunnel for redirection to be addressed to the second proxy node for transferring, and means that, when the second proxy node does not know the first prefix, makes the second home agent encapsulate the packet addressed to the first prefix that is redirected via the tunnel for redirection to be addressed to an address generated from the second prefix assigned to the second connection and further encapsulate the packet to be addressed to the second proxy node for transferring.
