  • Method and system for efficient extended data communications using GPRS
    Patent number: 8484370
    Abstract: A method and system for efficient extended data communications using a GPRS (General Packet Radio Service) carrier network. In a communications system having a server and client device coupled by a GPRS network, a communication session is initiated by the client. A combination of data packet transmission frequency adjustment and the transmission of “keep alive” packets are used to prevent carrier network time-out of the communication session. In multiple server environments such as those using load sharing, a queuing mechanism is provided for outbound messages to client devices.
