Method to sustain TCP connection

A computer-implemented system that facilitates management of client/server connections via unsolicited communication in a wireless environment, comprising:

• a server that manages active sessions with at least one client;
• a mobile client device that establishes an active session with the server and transmits an unsolicited keepalive packet to the server in order to keep the session alive;
• and
• wherein the keepalive packet is based upon a sending sequence field populated with a number whose value is one less than that expected by the server.

A computer-implemented method for conserving power in a mobile communication device while maintaining an active connection session between the mobile device and a base station, comprising:

• establishing a communication session between a mobile communication device and a base station;
• configuring the base station for terminating the communication session upon expiration of a keepidle timer;
• configuring the mobile communication device for transmitting keepalive signals to the base station at intervals prior to the expiration of the keepidle timer;
• transmitting the keepalive signal from the mobile communication device to the base station, the keepalive signal is at least one of transparent and unsolicited;
• and
• wherein the keepalive signal is based upon a sending sequence populated with a number whose value is one less than that expected by the base station.
