The heterogeneity of today's wireless access possibilities imposes challenges for efficient access and resource management across different radio access technologies (RATs). With upcoming 4G technologies and emerging mobile cloud computing, concepts such as fixed mobile convergence are driving the evolution toward comprehensive network management approaches. The proposed context-enhanced heterogeneous access management (HAM) concept accounts for network, terminal, and user context while simultaneously trying to accommodate users, facing different environmental conditions, with the best possible end-to-end performance. To quantify the potential benefit of incorporating context information, we present preliminary simulation results demonstrating that context-enhanced HAM systems will clearly outperform conventional systems.

“…In the following, we briefly describe the building blocks of MRM. For a more detailed description of MRM, we refer to [8,9]. Please note that these building blocks are common to all network-centric multi-radio management solutions and our further analysis is thus not limited to the MRM architecture.…”

Abstract. In this article, we present a multi-radio management (MRM) architecture for intelligent access selection and load balancing over multiple radio access technologies. We discuss possible implementations of this MRM architecture and analyze to what extent the IEEE 802.21 'Media Independent Handover' framework can be applied here. Starting from the fundamental building blocks of the multi-radio management architecture, we find several issues with respect to the integration with and the interworking between today's 3GPP and non-3GPP networks. Because support of 802.21 can largely differ from one access technology to another, we propose ways to compensate for these differences and finally present an adapted MRM architecture.

The availability of both static and dynamic context information has steadily been increasing in recent years. Accordingly, manifold use cases for this data, especially for consumer services, have been suggested. In this paper, we present a concept for how to use context information for intelligent radio network access (IRNA) purposes. Therefore, a context management architecture (CMA) is proposed that is able to handle context information and its respective providers and consumers efficiently. Since a Heterogeneous Access Management (HAM) imposes high requirements on context quality, especially with respect to availability, accuracy, delay, confidence, and relevance of context data, a context quality enabler (CQE) is integrated into the CMA. Finally, we describe the concept of a context-aware radio network simulator (CORAS) that models IRNA concepts, thus allowing for quantitatively evaluating the impact of user and network context information on simulation results.
