In his speech, Li Zhengmao said that the construction of 5G networks should be accelerated. Take the lead in formulating the world's first 5G SA Deployment Guidelines to promote the healthy development of the global 5G SA industry; build the world's first 5G SA commercial network and take the lead in achieving commercial scale. Cooperate with China Unicom to build the world's largest shared 5G SA network, and realise 5G network coverage in all urban areas of cities above prefecture level, urban areas of counties and some key towns across the country. Deepening of the basic network. Carry out gigabit optical network upgrades and 10GPON network construction around key cities and towns, covering 150 million homes in over 300 cities. Build a digital home all-optical gigabit WiFi network to achieve whole-home gigabit coverage; promote the expansion of home broadband services from whole-home Wi-Fi to all-optical gigabit Wi-Fi, providing users with large bandwidth, low latency, high quality and smoothly upgraded service carrying capacity to meet the demand for high-quality services. We are the first to propose the concept of "Arithmetic Network" and actively put it into practice. Based on ubiquitous network connectivity, it integrates multi-level arithmetic resources to achieve efficient collaboration between cloud, edge and network, improving the efficiency of arithmetic resources utilisation, achieving consistency in user experience and flexibility of services.

We need to accelerate the construction of a new type of cloud-network convergence information infrastructure. China Telecom is the first in the industry to put forward the direction of cloud-network convergence: "the network is the foundation, the cloud is the core, the network moves with the cloud, and the cloud-network is integrated", and to promote the transformation of enterprises from connection providers to cloud service providers. China Telecom is the second largest data centre service provider in the world, and Sky Cloud is the largest carrier cloud in the world and the fourth largest public cloud service provider in China. At present, we are actively promoting the construction of national clouds, further improving the layout of "2+4+31+X+O" cloud and big data centres in accordance with the construction requirements of national integrated big data centre hub nodes, and building a new information infrastructure with ladder distribution, cloud-side synergy, multi-technology integration and green intensification. The company will build converged resource pools in two national cloud bases in Mongolia and Guizhou; build large-scale public clouds in four regions, including Beijing, Tianjin and Hebei; build localised exclusive clouds in provincial capitals and key cities in 31 provinces; build differentiated edge clouds in X nodes; and lay out countries along the "Belt and Road" to extend its computing power system overseas.

To continue to enhance intelligent and agile capabilities. Rapidly promote the construction of a new generation of cloud network operation system, horizontally pull through the cloud, network, edge and end, vertically through the resources to customers, to provide intelligent and agile integrated information services. At present, the cloud transfer network infrastructure capacity has covered IP virtual private network, OTN, 5G custom network and other cloud network facilities, supporting cloud network convergence services instantly, realizing enterprise internal opening at the minute level and client installation at the day level, and is further expanding the coverage of multi-cloud docking. At the same time, we are actively promoting internal cloud access with digital intelligence, promoting the action plan of "100% of new systems in the cloud and three years of stock systems in the cloud", focusing on the construction of four cloud infrastructure platforms, and reaching an overall cloud access rate of 75% for the entire network. With the help of AI intelligence and digital transformation, the company has been able to improve quality, reduce costs and increase efficiency, for example, through the base station AI energy-saving platform, fully exploiting the energy-saving potential.

To adhere to the green low-carbon development model. With the overall green transformation of economic and social development as the leader, we will unswervingly take the high quality development path of ecological priority and green and low-carbon development, explore and form the "1236" green and low-carbon development model, and help achieve the "double carbon" goal. "1" is to adhere to a strategic focus, making green and low-carbon development an important element of the enterprise strategy. "2" is to grasp the two directions of force, internally strengthen technological innovation and management upgrade, and continuously reduce carbon emission intensity; externally optimize product supply and service quality, and empower the whole society with digital technology for green and low-carbon development. "3" is to practice three basic strategies, dealing with the relationship between energy saving and carbon reduction and the rapid development of 5G/IDC, full competition and open cooperation, and technological innovation and sustainable development. "6" is to promote six green actions, building a new green cloud network, creating a new green operation, constructing a new green ecology, empowering new green development, generating new green technology and building new green support. By the end of the 14th Five-Year Plan period, China Telecom has pledged to reduce energy consumption and carbon emissions by more than 23% per unit of total telecom services; to save more than 45 billion kilowatt hours of electricity through the construction and sharing of 4G/5G networks, and to save no less than 20% of energy in new 5G base stations; and to account for more than 80% of large and super-large green data centres, with the PUE of new data centres below 1.3. The PUE of new data centres will be lower than 1.3.

Finally, Li Zhengmao said that China Telecom will seize the strategic opportunity of the development of the digital economy, firmly implement the cloud reform and digital transformation strategy, take reform and innovation as the fundamental driving force, accelerate the completion of an intelligent and comprehensive digital information infrastructure, strengthen the deep integration with the real economy, support the digital transformation of thousands of industries, and make a new and greater contribution to the healthy development of the digital economy.。
