Patent ID: 6947400

Claim:
A method for transmitting information from a computer to a server comprising the steps of: (a) assigning a Mobile Internet protocol (IP) address to customer premise equipment (CPE) associated with the computer; (b) registering the Mobile IP address with a Mobile IP home agent associated with a home network for the assigned Mobile IP address; (c) initiating a point-to-point (PPP) session from the computer to a L2TP access concentrator (LAC) associated with the CPE; (d) encapsulating IP data from the computer into PPP frames and sending it to the LAC; (e) encapsulating the PPP frames into L2TP packets at the LAC; (f) directing the L2TP packets to a Mobile foreign agent associated with a mobile base station via mobile communications; (g) further encapsulating the L2TP packets at the Mobile IP foreign agent into Mobile IP packets; (h) transmitting the Mobile IP packets to the Mobile IP home agent associated with a base station; (i) unencapsulating the transmitted Mobile IP packets at the Mobile IP home agent into L2TP packets; (j) forwarding the L2TP packets to the L2TP network server (LNS) associated with the Mobile home agent; (k) unencapsulating the forwarded L2TP packets at the LNS into PPP frames; (l) further unencapsulating the PPP frames into IP packets; (m) forwarding the IP packets to the server; (n) sending IP packets intended for the computer from the server to the LNS where they are encapsulated into PPP frames, further encapsulating the PPP frames into L2TP packets; (o) sending the L2TP packets to the Mobile home agent where they are encapsulated as Mobile IP packets; (p) directing the Mobile IP packets from the Mobile home agent to the foreign agent associated with the registered CPE of the destination computer; (q) unencapsulating the Mobile IP packets at the foreign agent to uncover L2TP packets; (r) sending the L2TP packets to the destination CPE and having the LAC associated with the CPE unencapsulate the L2TP packets into PPP frames; and (s) sending the PPP frames to the computer.
