A transmission apparatus and method for compressing headers in a broadband wireless communication system are provided. Upon receiving a packet to which a real-time transport protocol (RTP) header, a user datagram protocol (UDP) header, and an Internet protocol (IP) header are added, from an upper layer, a header compression protocol layer transmits the received packet without compressing the headers at initial transmission, and from the next transmission, compresses the headers according to a compression scheme provided in Internet technology. A header compression convergence sublayer classifies the packet according to initial-header information received from the header compression protocol layer, stores mapping information for the packet classification, and performs packet classification on a header-compressed packet using the mapping information.
