%X SIP is used in IMS to perform multimedia session setup and maintenance. However, it is text-based and has large messages with sizes frequently exceeding several hundred bytes during the session setup. As a result, it causes more call setup delay. Based on the SigComp, a new algorithm with improved LZW and HUFFMAN is proposed in this paper, which is named as LZW-HUFFMAN. Simulation results prove that the new algorithm can effectively reduce the message sizes and shorten the session setup delay.
