Abstract :
Session initiation protocol (SIP) has already been accepted as the signaling standard in 3G wireless systems. However, the handover procedure with SIP suffers from undesirable delay in multimedia applications. The performance for real-time mobile communication is decided by multiple factors, we only focus on the handover delay due to host mobility in this paper, especially the delay accumulated during movement detection, duplicate address detection (DAD), SIP session reestablishment, and AAA procedure. This paper offers a fast handover solution for SIP-based mobility (named FMSIP for short). The proposed method utilizes movement anticipation, tunneling, and AAA context transfer to alleviate handover delay. The performance analysis and simulation results are presented at the end of this paper
