ABSTRACT:
A method and system is provided for transmitting information from a mobile computer to a server utilizing point-to-point protocol (PPP). The system enables a PPP session to be maintained between a mobile user device and a PPP termination device. A Mobile IP address is assigned to customer premise equipment (CPE) associated with the user device, e.g., a PC. The CPE includes a Mobile IP Mobile Node and L2TP access concentrator (LAC). The Mobile IP address is registered with a Home Agent. The PC initiates a PPP session to the LAC, which initiates an L2TP session to an L2TP Network Server (LNS) via a tunnel between the Home Agent and the a Foreign Agent. The Mobile IP Mobile Node registers with the Home Agent each time it detects a new base station. Thus, the Home Agent is informed of the new location to forward IP packets for the mobile computer.
