Abstract
A system, apparatus, and method for maintaining a socket connection over a wireless network. For example, one embodiment of the invention is a wireless data processing device for emulating a socket connection comprising: a wireless radio for establishing a wireless communication channel with a wireless service provider over a wireless network; a network protocol stack including at least one layer configured to establish a socket connection with a remote server over the wireless network, the network protocol stack further including an application layer for executing applications capable of transmitting and receiving data over the socket connection; and a resumable socket module configured to emulate an open socket connection transparently to applications within the application layer, even when the wireless communication channel is temporarily lost, the resumable socket module counting a number of bytes transmitted or to be transmitted to the remote server and maintaining a buffer containing the bytes transmitted or to be transmitted.
