Abstract
A method is disclosed for transmitting a packet from a correspondent node to a mobile node when the mobile node moves from a home network to an external network equivalent to the correspondent node's local network. The method may include securing a Care Of Address (COA) for the mobile node. The COA may be used to forward a packet intended for the mobile node by a home agent in the home network. The method may also include obtaining the COA at the home agent to update binding information on the mobile node, transmitting the updated binding information to a correspondent node, and setting a target IP address for the packet transmitted by the correspondent node. The target IP address may be the COA of the mobile node when the correspondent node's local network is the same as the external network where the mobile node is located.
