Abstract
A method for transmitting voice traffic in an ALL-IP-based mobile communication system. A mobile terminal first transmits header information using a signaling frame, and then separately transmits only a voice frame. A Node B detects the header information from the signaling frame received, stores the detected header information, and upon receipt of the voice frame, adds the header information to the voice frame and transmits the header-added voice frame to a core network.
