ABSTRACT:
A home agent, attached to a home network, receives, adapts and forwards messages intended for a mobile node attached to one of a plurality foreign networks. The home agent, having received a message, passes the message on to a processing unit to assess whether the message should be adapted so as to be compatible with the destination foreign network and to adapt the message accordingly. The adapted message is returned to the home agent to be encapsulated and tunnelled to a foreign agent attached to the destination foreign network. The foreign agent decapsulates the message and passes it on to the mobile node. This method has the advantage that the mobile node is able to receive messages regardless of the type of network to which it is attached.
