Abstract

Emerging broadband access technologies are enabling the introduction of IP services to an increasing number of users. The market forecasts suggest that a new class of network providers will deploy public wireless or not networks based on these new technologies. In order to offer uninterrupted IP service combined with ubiquitous seamless mobility, these multi-provider networks need to be integrated with each other. As the latest descendant of such networks, the IP Multimedia Subsystem (IMS) has been envisaged to build up the extra functionality required to bridge such functionality gaps, hence accelerate services harmonisation in the context of mixed technology networks. Based on IMS architectural perception as well on ETSI TISPAN architecture, this article presents a complementary study of NASS-IMS bundled authentication on a core network communication concept. Finally, it concludes by focusing on its performance assessment through comparisons to different core network architectures and density of users.
