ABSTRACT:
In a third generation mobile telecommunications network, when a mobile is in a foreign network, packets are addressed to it by a home agent which changes the header so that the source address is the home agent address and the destination address is the Care of Address of the mobile. Identifier codes for the mobile node and correspondent node are included in the packet header, and tables of identifier codes and the correspondent nodes are retained by the home agent and sent to a foreign agent (FA COA working) or mobile node (CO-COA working) which readdress each received packet, to a higher layer or to an application, as appropriate.In this non-encapsulated mode of working, packets are not rejected by a firewall or by egress filtering.
