MULTIPLE SERVICE METHOD OF DEDICATED DATA MOBILE COMMUNICATION SYSTEM

摘要

PURPOSE: A multiple service method of a dedicated data mobile communication system is provided to generate/complete many service instances according to traffic characteristics for one call connection, thereby supplying a transmission service according to the traffic characteristics. CONSTITUTION: An AT is assigned with a UATI(Unicast Access Terminal Identifier) from an AN(200). A session configuration is performed(205). The AN initially connects a traffic channel by assigning a wireless resource to the AT(210), and authenticates the AT(215). A PDSN(Packet Data Service Node) authenticates a user, and sets a PPP connection with the AT(220). The AT performs the second session configuration(225), and cuts off a set traffic path, then sets a new traffic path with the PDSN(230). A VoIP service or a video multimedia service begins(235). The AT establishes a new traffic path with the PDSN in a connected state(240). The AT and the PDSN exchange flow mapping rules, header processing methods, and full header information(245). A data stream is transmitted to generated service instances(250).
