AI Native 6G Core Network Architecture Discussion

This technical report discusses the emerging architecture of the AI native 6G core network, emphasizing three key attributes defined by the 3GPP: standalone operation, AI native integration, and service awareness. It outlines how these attributes are expected to converge in the development of the 6G core, particularly in preparation for the formal standards to be established in Release 21. The report addresses key issues being tackled in 3GPP SA2 to incorporate AI as a fundamental component of the core architecture. It also considers the implications of mobile AI traffic profiles on network design and the anticipated challenges associated with the integration of AI services. The report further elaborates on the evolution of core architecture based on prior technical studies, highlighting the importance of service-based architecture and the need for a new AI domain within the core network. Addressing both technical and operational dimensions, it presents insights on the potential for a new 6G core that is optimized for AI capabilities, while also cautioning against premature commitments to radical shifts in infrastructure.
