Deliverable D2.2: Overall SAFE-6G Framework and Reference Architecture Design

This deliverable establishes the SAFE-6G reference architecture, outlining key components, design principles, and specifications that will inform the development of the rest of the project. Taken as a whole, these elements provide a framework for the project's progress. Establishing the SAFE-6G architecture, outlining crucial elements, and formulating requirements for an end facility that will serve as a guide for numerous tasks are among the main goals. This deliverable outlines how the Service-Based Architecture (SBA) will develop toward a user-centric core, outlines how architectural components will interact, and evaluates the tools that can be used to realize those components. This document is the second deliverable of WP2 - D2.2: Overall SAFE-6G Framework and Reference Architecture Design and after this one follow the D2.3: Metaverse use-cases definition with virtual assistant for user-centric configuration (due in M12/December 2024) and D2.4: 6G Trustworthiness KPI & KVI definition and validation methodology (due in M14/February 2024).
