REAL TIME DATA TRANSMISSION SYSTEMS AND METHODS

摘要

A real time data transmission method is used in a network in which a real ti me media gateway is provided to allow access to the Internet backbone in additi on to the usual GPRS specific gateway. The method involves changing the header in a real tim e data stream as it passes through the network so that it can pass directly to the real time gateway without passing through the GPRS specific gateway. This ensures that the dat a stream travels along a more direct route and shortens the headers used in the data stream in the process.
