Although the 6G network architecture is still in the research stage, the white paper on China Mobile 6G network architecture technology (hereinafter referred to as the white paper) recently released by China Mobile has been regarded as a milestone in the development of 6G by the industry. This latest research achievement in the industry is the further enrichment of the development drivers, design concepts, overall design, system design, networking design and other contents of 6G network architecture by China Mobile on the basis of the 2020 white paper 2030+ network architecture outlook. Gaotongqing, deputy general manager of China Mobile, introduced that, like the skeleton and hub of the mobile communication system, the network architecture is the core of the 6G system. As one of the core symbols of the intergenerational development of mobile communication network, the foresight, feasibility and compatibility of network architecture design will directly affect the development path and application effectiveness of mobile communication network, which must be considered in advance. Wu Hequan, academician of the Chinese Academy of engineering, said that 6G network architecture is the focus of global attention. The white paper has made a forward-looking attempt and Exploration on the design of 6G network architecture, and creatively and systematically considered various elements such as digital twins and network security, which is very meaningful. The white paper emphasizes that the architecture design of 6G network should not only face the changes in the digital era and be highly in line with the national strategy, but also consider the drive of new scenes and new demands, and demonstrate the development trend and feasibility of introducing new technologies in cross-border fields. Xiang Jiying, chief scientist of ZTE, said: "the white paper creatively summarized the new features of 6G network architecture into three bodies, four layers and five sides. This is the first time that the industry has seen such a highly concise and easy to understand summary of network architecture features." According to the introduction of China Mobile, "three bodies" refer to the network ontology, management arrangement body and digital twin, "four layers" refer to the resource and computing power layer, the routing and connection layer, the service-oriented function layer and the open enabling layer, "five aspects" refer to the control surface, the user surface, the data surface, the intelligent surface and the security surface. 6G is the focus of technological innovation in the global mobile communication industry. Global communication technology powers, leading operators and technology companies have joined the ranks of 6G R & D. Although the technology research and development for 6G is still in the exploratory stage, when it will happen and how it will change human society are the issues that the public continues to pay attention to. According to the development rhythm of "one generation of use, one generation of construction and one generation of research and development" of the mobile communication industry, the industry predicts that 6G will be commercially available around 2030. According to the scenarios presented in the white paper on 6G's overall vision and potential key technologies released by the imt-2030 (6g) promotion group, 6G will further expand on the basis of 5g from serving people, people and things to supporting the efficient interconnection of agents, realize the leap from the interconnection of all things to the smart alliance of all things, and finally help human society realize the beautiful vision of "smart alliance of all things and digital twin". Youxiaohu, deputy director and chief scientist of Zijinshan laboratory and professor of Southeast University, said: "although 6G is a new generation of mobile communication after 2030, the development of 5g will lay the foundation for 6G. The gradual integration of 6G oriented technology with existing 5g technology and smooth transition will make the existing 5g investment more effective and the future 6G development more practical." In this regard, Zhang Ping, an academician of the Chinese Academy of engineering and a professor of Beijing University of Posts and telecommunications, also pointed out that the network architecture needs to be compatible and develop downward. It is necessary to pay attention to the role of intelligence on the factors of network simplicity, reduce the cost of network complexity through intelligence, and realize entropy reduction.
