Abstract
A method is provided of directing an internet protocol (IP) packet to a mobile node. The mobile node has a home address in a home network and is temporarily connectable in a foreign network having a foreign agent. The IP packet has a header portion including the destination address to which the IP packet is to be sent. The method comprises the steps of: receiving, in the home network, the IP packet including a destination address corresponding to the home address of the mobile node; modifying the IP packet by removing the home address of the mobile node from the header portion of the IP packet and replacing it with the foreign agent care-of address, and appending a mobile node identifier to the IP packet, and transmitting the modified IP packet.
