APPARATUS AND METHOD FOR PROVIDING EFFICIENT VOIP(VOICE OVER INTERNET PROTOCOL) IN MOBILE TELECOMMUNICATION SYSTEM

摘要

Disclosed are apparatus and method for efficiently processing voice packet data in a mobile communication system providing voice service using a packet network. The method includes: receiving a voice packet from an upper layer and generating a header including information about voice packet type and information for checking of voice packet error; confirming a data field of the voice packet based on the packet type and determining an error detection range; reconstructing a voice packet including the error detection range and the header and transferring the reconstructed voice packet to a lower layer. The apparatus and method can perform decoding with proper CODEC for an erroneous voice packet, thereby improving the quality of voice communication.
