Abstract: The diverse and heterogeneous terminal artificial intelligence (AI) agents and network-element AI agents are flourishing in a flywheel-like manner. The new characteristics of their capabilities and behaviors will reshape the service paradigm and traffic logic of future mobile information networks. This article first elaborates on the dynamics of the intertwined and integrated development of the AI agent/robot industry and the wireless communication industry. Then, based on an analysis of the new capabilities and behavioral characteristics of termi‑ nal AI agents and network-element AI agents, the article deduces a new design paradigm for future AI agent-centric (AA-Centric) networks, which includes seven core features: intent-driven, proactive service, distributed collaboration, efficient customization, deterministic guaran‑ tee, online evolution, and infinite generation. Guided by this new paradigm, the new architecture of 6G networks is further deduced, and the key supporting technologies are expounded. Finally, it is concluded that AI agents play a crucial role in driving the innovation of future net‑ work architectures and the ultimate expansion of capabilities.
