“…Although some papers such as [14], [15], and [16] consider context-aware service provisioning, unlike our proposed solu tion, their studies did not address end-to-end QoS provisioning in converged networks. Another way that the work in this pa per differs from the aforementioned is that it explores the mod elling of policy-driven processes using stochastic-analytic tools (specifically Markov Chains) as a cost-effective method to evaluate the impact of context-driven policies in a CNQF case study scenario (in section IV).…”

“…For example, in [13], using Radio Frequency Identification (RFID), a solution for personal mobility (not session continuity) is proposed for a SIP network that resolves RFID with SIP user identification. In [17] [18], authors propose a special proxy (loosely couple application interaction proxy [17], context-aware SIP proxy [18]) for the SIP network. Even though these proxies are incomplete and more general, they suffer from scalability when many users access the proxy simultaneously.…”

To support user mobility across different devices, communication session continuity should be enabled at session initiation and during a session. The session continuity can be managed by either a user or dedicated network nodes such as back-to-back user agent (B2BUA) in IP Multimedia Subsystem (IMS) architecture. When network manages the session continuity, user experience is enriched because users do not need to know how to perform session transfer. However, in IMS architecture, three different network nodes (SIP forking proxy, SIP registrar and B2BUA) need to cooperate for session continuity. When single user (callee) logs in from different devices, it is very hard to achieve cooperation. In addition, these network nodes should be scalable when many users request this service simultaneously. This paper proposes a general architecture that supports the user mobility and how the general architecture can be realized into a Web-based communication system. Our initial analytical result shows that the usage of computing resources (e.g. CPU) is reduced while supporting scalability, thanks to the simple Web client service infrastructure and Web Socket connections on top of HTTP.

Abstract-This paper presents a framework for context-driven policy-based QoS control and end-to-end resource management in converged next generation networks. The Converged Networks QoS Framework (CNQF) is being developed within the IU-ATC project, and comprises distributed functional entities whose instances co-ordinate the converged network infrastructure to facilitate scalable and efficient end-to-end QoS management. The CNQF design leverages aspects of TISPAN, IETF and 3GPP policy-based management architectures whilst also introducing important innovative extensions to support context-aware QoS control in converged networks. The framework architecture is presented and its functionalities and operation in specific application scenarios are described.
