Signaling Compression for SIP
Zhengkun Mi · Journal of Nanjing University of Posts and Telecommunications · 2008
Signaling Compression(SigComp)is a kind of information compression technology designed originally for IP signaling protocols in Internet multimedia sessions,which can be used in wireless communication.The purpose of SigComp is to reduce bandwidth overhead and improve the usage of radio spectrum resource.In this paper,a detailed introduction is described to SigComp architecture,entities function,message format and extended operations.A SigComp compressor is implemented using LZHUF compression algorithm together with static dictionary and shared compression mechanisms.The simulation results show that the compressor demonstrates a good performance.The size of the compressed message,on the average,is around 20% of the original message size.
