ABSTRACT Although Session Initiation Protocol(SIP) has been the main choice of terminal mobility signaling solution in application layer, it is obvious that SIP suffers from considerable handover delay that is not suitable for real-time multimedia and frequent local movements(intra-domain handovers). By introducing Session Border Controller(SBC) and hierarchical SIP registration, this paper proposes a novel intra-domain mobility management architecture which can support seamless vertical handover, location transparency and NAT traversal. Based on the architecture, an intra-domain vertical handover procedure is proposed, using Advance Duplicate Address Detection(A-DAD) to reduce the handover delay. Performance analysis has evaluated the handover delay and indicated that the proposed handover procedure can fulfill the delay requirement of real-time applications.
