Integrated SIP and HCoP-B Architecture for Nested Network Mobility

摘要

In this paper, we propose a fully-integrated SIP+HCoP-B architecture to provide efficient mobility management of the nested mobile network. It achieves the following merits as compared to traditional SIP over NBS and SIP over HCoP-B architectures. First, it reduces network deployment costs by only equipping an integrated SIP mobile server, instead of both SIP home registrar and Mobile IP home agent, for each mobile router. Second, it achieves the smallest signaling overhead and the shortest session initialization latency. Finally, it supports both SIP-based and non-SIP-based applications.
