Although the 6G network architecture is still in the research stage, the "China Mobile 6G Network Architecture Technology White Paper" (hereinafter referred to as the "White Paper") recently released by China Mobile has been regarded by the industry as 6G development. milestones in.
This industry's latest research result is based on China Mobile's 2020 "2030+ Network Architecture Outlook" white paper, development driving factors, design concepts, overall design, system design, network design and other content of 6G network architecture further enriched.
Gao Tongqing, deputy general manager of China Mobile, said that just like the skeleton and center 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 networks, the forward-looking, feasibility, and compatibility of network architecture design will directly affect the development path and application effectiveness of mobile communication networks and 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" conducts forward-looking attempts and explorations of 6G network architecture design, and innovatively and systematically considers digital twins, network security and other aspects. elements, very meaningful.
The "White Paper" emphasizes that the architectural design of 6G networks must not only be oriented to the changes in the digital era, be highly consistent with national strategies, but also consider the drivers of new scenarios and new demands. It must also demonstrate the development trend of new technologies in cross-border fields and the introduction of new technologies. feasibility.
ZTE’s chief scientist Xiang Jiying said: “The White Paper innovatively summarizes the new features of 6G network architecture into three-body, four-layer, and five-side. This is the first time the industry has seen such a highly concise and popular An easy-to-understand summary of network architecture features. "
China Mobile introduces, " three-body " refers to the network ontology, management and orchestration body, and digital twin. " four-layer " refers to the resource and computing power layer, routing and connection layer, The service-oriented functional layer and open enabling layer, " five-sided " are the control plane, user plane, data plane, intelligent plane and security plane.
6G is the focus of technological innovation in the global mobile communications industry. Global communications technology powers, leading operators and technology companies have all joined the 6G research and development ranks.
Although the technology research and development for 6G is still in the exploratory stage, when will it happen and how will it change human society are issues of continued public concern.
According to the development rhythm of the mobile communications industry of "use one generation, build one generation, and develop one generation", the industry predicts that 6G will be commercially available around 2030..
According to the scenario shown in the "6G Overall Vision and Potential Key Technologies White Paper " released by the IMT-2030 (6G) Promotion Group, 6G will further expand from serving people, people and things on the basis of 5G to supporting intelligent agents. Efficient interconnection realizes the transition from the Internet of Everything to the Intelligent Internet of Everything, and ultimately helps human society realize the beautiful vision of " Intelligent Internet of Everything, Digital Twin ".
Deputy Director and Chief Scientist of Purple Mountain Laboratory and Professor of Southeast University You Xiaohu said: "Although 6G is for the new generation of mobile communications after 2030, the development of 5G will lay the foundation for 6G. For 6G The gradual integration of technology with existing 5G technology and smooth transition will make existing 5G investments more effective and future 6G development more solid."
In this regard, Zhang Ping, academician of the Chinese Academy of Engineering and professor at Beijing University of Posts and Telecommunications, also pointed out that the network architecture needs to be upwardly compatible and downwardly developed. It is necessary to pay attention to the role of intelligence in network simplicity factors and reduce network complexity through intelligence. At the cost of achieving entropy reduction
