【 Main measures 】

In March 2020, the Ministry of Industry and Information Technology held a special meeting to accelerate the development of 5G, 5G as a key new infrastructure to support the digitalization, networking and intelligent transformation of the economy and society, 5G has become the "fist soldier" of the "new infrastructure". 5G network brings higher speed, wider bandwidth, lower latency at the same time, base station power consumption is inevitable. According to the Global System for Mobile Communications Association (GSMA), upgrading to support 5G networks in current operating scenarios will require an increase in energy consumption of at least 140%. According to the development of communication networks and use terminals, in a long period of time, 5G networks will coexist with the stock of 2G/3G/4G networks, and the increase in energy consumption will be a thorny problem that operators have to face in large-scale deployment of 5G networks.

At present, communication energy saving has been included in the overall design of "14th Five-Year Plan" energy saving and carbon reduction and the national carbon peak carbon neutral major decision deployment, in the context of advocating green and low-carbon development, energy saving and consumption reduction, improving network energy efficiency is the only way to sustainable development of the future mobile communication industry. At present, the overall energy consumption of 5G base stations is mainly concentrated in the four parts of base station, transmission, power supply and room air conditioning, and the electricity expenditure of base stations accounts for more than 80% of the overall network energy consumption. How to reduce the operating energy consumption of base stations and further reduce operating costs has become an increasingly urgent problem. However, the current operators in the face of the problem of new base station construction and maintenance of old base stations, there is still a lack of energy consumption management of ancillary equipment for a long time or even 24 hours, resulting in excessive energy consumption, the huge number of communication base stations due to a wide range of base distribution, complex terrain and a series of reasons, resulting in operation and maintenance difficulties, the required energy saving and emission reduction costs are significantly higher than ordinary industries.

China Mobile took the lead in releasing the "Green 5G Initiative" in May 2021, which plans to reduce base station energy consumption by 25%, and other operators are also actively following up to jointly explore advanced technologies of the Internet of Things, big data and cloud computing. China's 5G construction has been nearly 3 years, and the number of 5G base stations has opened more than 1.35 million, and the number of 5G base stations has accounted for more than 72% of the global proportion. In 2020, the carbon emissions of 5G base stations in China will reach 27.99 million tons, and the overall energy consumption of 5G base stations is mainly concentrated in four parts: base station, transmission, power supply and air conditioning in the equipment room, whose energy consumption includes the main equipment energy consumption (BBU and AAU) accounting for 46%. Air conditioning energy consumption accounted for 46%; Electricity distribution and other energy consumption accounted for 8%. At present, operators mainly use "network architecture reconstruction, power supply mode optimization, temperature control intelligent adjustment" and other carbon reduction measures to promote energy digitization and reduce energy consumption per unit of information flow.

Based on the application of the new generation of information technology and environmental energy-saving technology, ZTE Communication Technology develops the evaluation standard - "Technical Specification for Evaluation of Green Design Products Intelligent energy-saving Equipment for Communication base Stations" under the premise of maintaining technological advancement in design and production. From the three centers of "green product design", "product energy efficiency" and "use of clean energy" of green products in the green manufacturing standard system, we explore the environmental friendliness, resource saving and energy saving of base station energy-saving equipment, and improve the evaluation standards of green product design in the subdivision field.

In terms of standard construction, from the two dimensions of "intelligent energy saving" and "green operation and maintenance", it guides the green development direction of telecom base station environmental energy saving technology and energy saving equipment, promotes the formulation of relevant local standards, promotes the integration management standardization of energy consumption collection, energy consumption management and energy consumption analysis of base stations, and reduces power energy consumption by more than 50%. Improve the weak links in the management of energy-saving base stations, significantly reduce the number of stops and labor intensity of base station operation and maintenance personnel, save a lot of manpower, material resources and energy, and have significant social and economic benefits for the entire communication industry to reduce the operation energy consumption of base stations, and promote energy digitalization under the national low-carbon energy saving strategy "carbon peak, carbon neutrality" goal. Promote the realization of low-carbon energy saving and emission reduction targets in the communications industry, and jointly build a zero-carbon intelligent society.

In terms of green, low-carbon and energy-saving technology, the EGC solution independently developed by the company is based on the premise of meeting the normal working environment requirements of the communication equipment in the communication base station. First, through the intelligent energy-saving subsystem, the effective cold source is introduced from the outside to exchange with the indoor heat source, reducing the indoor temperature to save electricity; The second is accurate and efficient control of air conditioning output to greatly reduce the running time to achieve energy saving; The third is the use of outdoor 5G integrated cabinet energy-saving new products and the original cabinet high temperature transformation, to achieve environmental control, data upload, remote alarm processing, video surveillance, four remote. The intelligent energy saving system also has auxiliary energy saving functions such as ventilation and energy saving, accurate heat conduction, wind and solar complementation, and energy storage. It also works with the branch calculation energy collection subsystem and the remote management subsystem such as EGC Integrated Energy management Cloud Platform, EGC wechat Management mini program, and third-party energy monitoring Platform. It fully realizes intelligent energy-saving functions such as remote communication, telemetry, remote control, remote fault warning, itemized energy consumption collection, energy consumption data analysis and management for communication base station environmental control equipment (air conditioning, energy saving system).
