Abstract
An apparatus for keeping a VPN session alive on a portable computer system such as a laptop computer includes a processor that executes instructions that implement application software. The laptop computer system also includes a wireless module that may communicate with a wireless network such as a wireless wide area network including wireless telephone networks, for example. In addition, the wireless module may establish a virtual private network (VPN) connection with a computer network via the wireless network. The wireless module includes a processing unit that may execute instructions that cause information to be transmitted to a host portion of the virtual private network connection at one or more predetermined times.
