Method for providing mobile packet data service in mobile communication system

Abstract

A method for performing packet data communication between a mobile station (MS) and a packet data serving node (PDSN) in the next generation mobile communication network. In accordance with the packet data communication method, a traffic channel is set up between the MS and a radio network (RN), and a packet connection is set up between the RN and the PDSN. The MS and the PDSN exchange a data packet by means of an Internet protocol (IP) session without setting up a point-to-point protocol (PPP) layer connection. Therefore, unnecessary bytes of a PPP packet can be removed, and a negotiation process for setting up a PPP layer connection and time delay due to the negotiation process can be removed. An operation of transmitting IP information for the MS that is conventionally performed in the PPP layer connection setup process is performed using a broadcast/multicast Internet protocol (IP) packet, in a packet data service method in the mobile communication network.
