In today’s world, wireless communication systems and Internet are increasingly becoming interconnected. In order to seamlessly integrate them, concepts for intelligent Information and Communication Technology (ICT) architectures need to be developed. These architectures describe how context-aware systems efficiently provide tailor-made applications and content to the consumer, thereby adhering to the latest standards in terms of Quality of Service, ubiquity, and user privacy. A major conceptual challenge is the incorporation of technical enablers to design scalable, extendable, reliable and secure architectures. Therefore, system modularity is a key design paradigm that, in later stages, also supports a rapid adoption by the market. This in turn, facilitates the achievement of overall objectives satisfying human communication needs in a cost-effective manner..
