Over the past decade, technological advancements have reshaped the wireless communication landscape. The evolution of 5G has facilitated the deployment of “data-hungry” services, like enhanced Mobile Broadband, massive Machine-Type Communications, and Ultra-Reliable Low-Latency Communications, which will evolve further through next-generation Smart Networks and Services in the 6G transition. The 6G vision to establish an intelligent, adaptive ‘network of networks’, integrating communication technologies, computational resources, and AI models will lay the groundwork for an increasingly complex, diverse, and intelligent digital ecosystem, where Artificial Intelligence/Machine Learning and Native AI-driven automation are fundamental. However, key challenges remain: integrating diverse technologies, establishing robust frameworks for interoperability, achieving trustworthiness, and providing Service Level Agreement performance guarantees across varying operational conditions.

FLECON-6G aims to develop an innovative blueprint for 6G architecture, characterised by distributed, modular, open, and collaborative frameworks. Built on trustworthiness principles, it will feature multi-layer Network Digital Twins (NDTs) spanning resource management, control, and business layers. Central to the project is the vision of an “Intelligent 6G Network of Networks,” enabling seamless integration of Native and Trustworthy AI. This architecture will support automated, scalable service composition and capability integration. By leveraging strengths across networks, subsystems, and domains, FLECON-6G will enable collaboration among diverse stakeholders.
