This white paper presents a comprehensive snapshot of the current architectural
considerations explored by the Smart Networks and Services Joint Undertaking (SNSJU) projects. It aims to discuss the rationale for novel architectural components, the ongoing design efforts, and the future outlook for 6G. We analyse the blueprint for next-generation mobile networks, building on past experiences while integrating cutting-edge advancements. The structure follows the IMT-2030 framework, categorizing insights into the key usage scenarios and overarching architectural aspects.
• Usage Scenarios: We analyse the evolution of IMT-2030 paradigms, focusing on
Immersive, Massive, and Hyper-Reliable Low-Latency Communications. We also
explore novel 6G enablers, such as Ubiquitous Connectivity, AI-driven
Communication, and Integrated Sensing & Communication.
• Overarching Aspects: The next-generation architecture must natively embed
Security, Privacy & Trustworthiness, Sustainability, and Network Exposure
Capabilities—ensuring these critical aspects are foundationally considered
rather than retroactively incorporated
