Abstract

Over the past decade, multimedia services have gained significant acceptance and played an important role in the convergence of IP networks. The proliferation of mobile devices and the nomadic user and computing lifestyles on current networks make mobility support a crucial ingredient of current IP-based multimedia systems. The Session Initiation Protocol (SIP) presents one approach towards supporting IP mobility. Additionally, SIP is increasingly gaining in popularity as the next generation multimedia signaling and session establishment protocol, and the SIP infrastructure is anticipated to be extensively deployed all over the Internet. We have lately proposed an approach to inter-domain SIP mobility which we call H-SIP. H-SIP is a user-controlled mobility scheme that improves personal and terminal mobility. H-SIP uses persistent identifiers and leverages the traditional SIP architecture to abstract any domain binding from users. This paper expands on our previous work and experimentally proves the efficiency of H-SIP in achieving inter-domain authentication and call routing through modeling and real-time measurements.
