Abstract: Mobile communication networks have emerged as an indispensable infrastructure in contemporary society. As the next-generation communication technology, 6G networks will not only mark a significant leap in communication performance, but more importantly, necessitate the deep integration of multiple fields such as communication, sensing, computing, and artificial intelligence (AI). The article first examines the driving forces behind 6G networks, including the demands of service evolution and the challenges in network construction, operation, and maintenance. Subsequently, it elaborates on the pivotal design transformations in the 6G network architecture, encompassing the transition from a siloed multi-capability model to an integrated fusion of communication, sensing, computing, and AI capabilities, from offering a single service to providing differentiated services leveraging these multi-capabilities, from an added-on AI approach to a native AI, and from post-hoc high-cost handling to proactive low-cost intervention. Finally, the article introduces the key technologies of 6G network architecture, including cloud-native and service-based RAN, native AI, and network digital twin. These technologies collectively offer robust support for the efficient, intelligent, and flexible operation of 6G networks.
