This research explores how Large Language Models can transform 6G network architecture by enabling holistic intelligence and end-to-end automation across network segments.

• Addresses limitations of traditional 5G siloed management approaches
• Proposes LLM-based solutions for handling the hyper-complexity of 6G networks
• Outlines key innovations in design-driven security policies
• Establishes architectural frameworks for AI-network integration

The findings represent a paradigm shift in telecommunications engineering, where LLMs serve as central orchestrators capable of unifying network management across previously isolated domains, ultimately enabling more resilient and adaptable 6G infrastructure.
