(WG2) has been active in the area of service architectures for future wireless systems. The vision of I-centric communication has been developed putting the individual user (" I ") in the center of service provisioning rather than offering inflexible services that are unaware of actual customer needs or situations. I-centric systems relieve the user of(More)
This paper examines the international, inter- organizational collaboration processes for the development of cognitive radio, which will be at the basis of potentially profound changes in the telecommunications value network, as well as its functional architecture, cost and value structure and the eventual value proposition of any services deployed in such a(More)
The environments of software development and software provision are shifting to Web-based platforms supported by Platform/Software as a Service (PaaS/SaaS) models. By elaborating on these concepts, their benefits and risks, mobile operators' experiments with these models are analysed and similarities are identified. This paper will argue that mobile(More)
Recent advances in wireless communication theory and semiconductor technology brought wireless to virtually every aspect of our life, and this trend is expected to continue to increase in the future. Unfortunately, as the number of wireless applications grows, the same scarce spectrum is reused over and over again, resulting in increased interference, which(More)
