Abstract :
IMS was introduced into R5 core network by 3GPP, and SIP was chosen as the call/session control portocol. However, CSIP message´s size is becoming a performance bottleneck. Based on the SigComp, this paper gives a new compression algorithm. It includes LZSS and Huffman with pretreatment. And this paper gives a SigComp session delay model. Simulation results prove that the new algorithm can effectively improve performance, reduce the message sizes and shorten delay.
