Abstract
SIP (Session Initiation Protocol) has been chosen as the core signaling protocol of the NGN (Next Generation Network), but the large SIP message which is text-based is an obstacle with the planned usage of SIP in wireless mobile networks. Based on the SigComp (Signaling Compression) framework, some further improvements are made to the Deflate algorithm according to the characteristics of SIP in this study. Experiments show that the improved Deflate algorithm can compress the SIP message greatly and reduce the bandwidth requirements signally, so it is highly valued in IMS (IP Multimedia Subsystem), PTT (Push To Talk) and other wireless real-time SIP applications.
