Welcome Message from the Chairs

: The talk will be why, what and how of 6G and present some potential solutions that address these challenges. These challenges relate to future wireless, ubiquitous coverage and Core network that underpin concept of Future Network of Networks. Prof. Ari Pouttu has scientific and engineering experience as a researcher, project manager and research manager in various domains of ICT development. The projects under his command have resulted in waveforms and system designs for military radio communication, radar systems, embedded device networks, future wireless radio communications including cellular systems, cognitive networks and navigation applications. He has published more than 70 conference or journal papers in the field of wireless communications and he holds two patents. He is the principal investigator of 5G test network (5GTN) experimental research, and vice-director of the national 6G Flagship Programme as well as 6GESS programme targeting 6G solutions including wireless solutions for business verticals such as energy, industry, health and automotive. Abstract: The architectures of mobile networks have seen an unprecedented techno-economic transformation, fusing the telecommunications world within the cloud world, adding the spices of Software Engineering to the overall system design, and ultimately yielding the concept of Telco Cloud. This has brought significant benefits in terms of reducing expenditure and operational costs, flexibility in deployment, and faster time to market. The key enablers are network function virtualization, software-defined networking, and edge/cloud computing. Artificial intelligence is also kicking in this arena. When all these technologies are well integrated, the creation and life-cycle management of fully programmable, flexible, service-tailored, and automated end-to-end network slices/services become possible. This will support diverse 5G and beyond 5G services, spanning from tactile IoT to pervasive robotics and immersive services. In this talk 6G Flagship introduces an unprecedented and disruptive vision for 6G that shifts the perception of future mobile networks from the old-fashioned concept of “network of networks” towards a new vision of “service of services.” The talk then introduces the functional model of the envisioned system architecture, along with its components. It then provides a high-level description of the logical architecture.
