Organic 6G networks: Decomplexification of software-based core networks

This article proposes a new service architecture for 6G core networks based on the advancements in software services adopted by the IT industry. Through reconsidering the 5G Service Based Architecture (SBA) functional split, we propose a new 'Organic 6G Network' concept. It provides a fresh perspective on how to achieve the functional goals of 6G networks, while at the same time providing more adaptation capabilities and decreasing the overall system complexity. Specifically, this article concentrates on the complexity analysis, by providing for it a comprehensive concept definition, an understanding of the elements generating it in the current 5G architecture, and by providing a new direction on how to tackle its reduction. A thorough analysis of the new concept is also presented, clearly underlining how the proposed 'Organic 6G Network' architecture has the potential to greatly reduce the complexity while at the same time to outperform the flexibility of the current 5G network, making it a high potential alternative for the 6G networks.
