According to data from the Ministry of Industry and Information Technology, as of the first quarter of this year, China has a total of 2.646 million 5G base stations, 620 million 5G mobile phone users, and gigabit access users exceeding the scale of one billion. China has built the world's largest and technologically advanced network infrastructure. At the 2023 World Telecommunication and Information Society Day Conference held recently, experts said that we should speed up the construction of intelligent and comprehensive digital information infrastructure, open up the information "artery" of economic and social development, lay a solid foundation for the development of deep integration of data and reality, and enable Chinese path to modernization. Zhang Yunming, Vice Minister of Industry and Information Technology, stated that the information and communication industry should promote the modernization of the infrastructure system, optimize layout, structure, function, and system integration, accelerate the construction of high-speed ubiquitous, heaven earth integration, cloud network integration, intelligent agility, green low-carbon, safe and controllable intelligent comprehensive digital information infrastructure, and consolidate the foundation of high-quality development. Currently, China's network capacity continues to improve, and the network infrastructure is becoming increasingly complete. "The 5G and gigabit optical networks have been deeply covered, the" East Data and West Computing "project has been launched in an all-round way, the construction of computing infrastructure has been accelerated, the all-round, multi-level and three-dimensional internetworking architecture has basically taken shape, and the network service quality has accelerated to the world-class level," said Huang Yejing, deputy director of the Information and Communication Administration of the Ministry of Industry and Information Technology. According to statistics, as of the end of March, China has over 17.93 million ports with gigabit network service capabilities, achieving "city to city gigabit connectivity" and "county to county 5G connectivity". A hierarchical optimization of computing power supply system has been preliminarily constructed, with the scale of computing power ranking second globally and an annual growth rate of nearly 30%. IPv6 (Internet Protocol 6th Edition) has moved from "usable" to "user-friendly", with mobile network IPv6 traffic surpassing IPv4 traffic for the first time, accounting for over 50%, ushering in the era of IPv6 dominated internet. At the opening ceremony of this conference, the Hefei National Internet Backbone Direct Connection Point was officially opened, which is also the 22nd approved direct connection point for construction in China. Wang Zhiqin, vice president of the China Academy of Information and Communications, said that in terms of network infrastructure, China's dual gigabit network development has taken the lead in the world. At the same time, China is actively building a national Internet backbone network, which will further optimize the network architecture and business experience. The IPv6 transformation of the operator's network has been basically completed, and the application level of "IPv6+" technology represented by SRv6 is internationally leading. At the same time, coordinated by the Ministry of Industry and Information Technology, China Telecom, China Mobile, China Unicom, and China Broadcasting and Television jointly announced the launch of the world's first 5G cross network roaming trial commercial operation in Xinjiang. 5G cross network roaming refers to the ability of users to access other operators' 5G networks and continue using 5G services when their respective operators do not have 5G network coverage. Its deeper significance lies in further improving the level of co construction and sharing. Co construction and sharing is the main theme of 5G construction. Since the commercialization of 5G, China Tower has undertaken a total of 1.89 million 5G base station construction projects, accounting for more than half of the global total. 96% of 5G station sites are achieved through sharing existing resources, which not only accelerates network deployment, but also greatly reduces network construction costs, helping China's 5G commercial development lead the world. At the same time, collaborative telecommunications operation enterprises have accumulated a total of
