APPARATUS AND METHOD FOR CALL-SETUP IN A COMMUNICATION SYSTEM

摘要

An apparatus and a method for transceiving data in a communication system are provided to perform data transceiving using an SIP and acquire data service information corresponding call setup and call release through the SIP message in an MAC layer, thereby performing call setup of the MAC layer without receiving special application layer information. An MAC(Media Access Control) layer of an MS(Mobile Station) detects an SIP(Session Initiation Protocol) message, and analyzes and stores call information through the SIP message to acquire information about call setup between application layers(411). If call setup between the application layers is completed, the MS requests generation a call between the MS and an MAC layer of a corresponding MS to which data will be transceived(413,417). The MS receives a DSA-RSP(Dynamic Service Addition-Response) message corresponding to DSA-REQ(Rquest) message transmission(419). The MS transmits the DSA-ACK message to the corresponding MS(421). After that, the MS completes call setup of the MAC layer through the above transceiving processes of the DSA message(423).
