A Next Generation Network (NGN) is an advanced, packet-based network that exploits multiple broadband, QoS-enabled transport technologies to provide telecommunication services. The objective of NGN is to focus on users and those service-related functions that are independent of underlying transport-related technologies. With the advent of NGN, services that are currently provided by multiple specific network-centric architectures are migrated toward a single, converged, user-centric communication network. NGN provides AAA (Anytime, Anywhere and Always on) access to users from different service providers with consistent and ubiquitous provision of services as necessary. The principles and requirements of Convergence of Fixed and Mobile Networks (FMC) and IP Multimedia Sub-layer (IMS) are likely to deliver all the desired benefits of NGN and should be carefully examined and studied. This special issue is intended to foster state-of-the-art research in the area of NGN. The issue focuses on a range of NGN-related topics including cross layer design, mobility, security, services, business models, and novel applications associated with their utilization. Contributions to this special issue focus on all aspects of NGN and present novel results and solutions to solve various problems and challenges foreseen in future NGN. The call for papers for this Special Issue was overwhelmingly welcomed by scholars from around the world. It attracted 74 submissions from Asia, Europe, and the U.S. covering many topics related to NGN. Each paper was carefully evaluated by at least two reviewers. Based on the review results, we selected 25 high-quality research papers to be included in this Special Issue. We strongly believe that the selected papers will make a significant contribution to researchers, practitioners, and students working in the area of the NGN. Our special thanks go to Dr Mohammad S. Obaidat (Editor-in-Chief) and Mr Gareth Watkins for their valuable support throughout the preparation of this Special Issue. We would like to thank all authors who have submitted papers to the Special Issue and in particular those whose papers have been accepted for this Special issue. Assistance from the editorial staff of the International Journal of Communication Systems is also very much appreciated. Finally, the Guest Editors wish
