METHOD AND APPARATUS FOR PROVIDING VOICE OVER INTERNET PROTOCOL SERVICE IN MOBILE COMMUNICATION SYSTEM

摘要

The method of providing a VoIP service in a terminal of a mobile communication system includes extracting header information by analyzing an SDP offer message that is included in an SIP signaling message received from a WiMAX system; generating a CS rule using the extracted header information; determining whether to generate a new service flow using the extracted header information, and generating a PHS rule using a DSA in the case where the new service flow is generated, while generating the PHS rule using a DSC in the case where the new service flow is not generated; and transmitting the generated CS rule and PHS rule to the WiMAX system.
