摘要

A wireless communication terminal (100) includes a TCP connection keep-alive timer, and a controller configured to optimize keep-alive timer operation by reducing the frequency with which the terminal transmits keep-alive messages. In one implementation, the controller re-sets the keep-alive timer, before expiration thereof, upon sending or receiving a message at the terminal during a TCP connection, wherein the terminal transmits a TCP connection keep-alive message only upon expiration of the keep-alive timer. The terminal may transmit a register request message indicating whether the terminal supports optimized keep-alive timer operation.
