1. A transmission apparatus for transmitting a signaling frame and a voice frame to a reception apparatus in a CDMA (Code Division Multiple Access) mobile communication system having an ALL-IP (Internet Protocol) network, comprising:
- a signaling frame transmitter for transmitting header information, needed to transmit a voice frame to a destination, to the reception apparatus through a signaling frame during a call setup at a call attempt request of a user over a first channel; and
a voice frame transmitter for constructing the voice frame using header information identification and voice data to be transmitted, upon completion of the call setup, and transmitting the constructed voice frame to the reception apparatus over a second channel different from the first channel,wherein the header identification information is a code used for the voice frame transmitted through the second channel.

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.
