Description

TECHNICAL FIELD

[0001] The application belongs to the field of mobile communication, and particularly relates to an energy-saving method based on a 5G network. BACKGROUND

[0002] The key technologies of 5G new air interface, large-scale MIMO and dense networking enable the 5G network to have the characteristics of high speed, large bandwidth, low latency and high reliability, and become the mainstream communication technology in recent years, which brings exponential growth of 5G application and data flow, but also increases the network load and greatly increases the power consumption of base stations. With the large-scale construction of 5G, it is predicted that the energy consumption expenditure will account for about 30% of the entire operation cost of operators, which brings great pressure to the investment and operation of 5G network of operators. The energy consumption will be the key direction of cost reduction and efficiency improvement for the construction and operation of 5G network. The unique characteristics of 5G devices and technologies require new ideas for 5G network energy saving, multi-scheme cooperation and construction of low-cost and high-efficiency green network.

[0003] The technologies that can be used to realize 5G network energy saving are various, such as engineering application energy saving methods such as minimalist station construction and C-RAN, device-level energy saving methods such as symbol shutdown, channel shutdown, carrier shutdown and deep sleep, and device-level basic energy saving methods such as chip technology, device and heat dissipation. These energy saving means are the cornerstone of 5G network energy saving, and can be realized alone, but require large amount of manual analysis and manual configuration, lack of whole network cooperation, have great influence on network performance, and the energy saving effect is not obvious. The main problems are that the energy saving strategy is fixed, a large amount of manual data analysis is required, the influence on network performance is ignored, the KPI is deteriorated, the strategy lacks foresight, etc. Even if various AI intelligent energy saving methods are proposed, the energy saving effect is not satisfactory due to the lack of cooperation of energy saving methods. 5G network energy saving is a systematic project, and the network is constantly changing, which requires the use of AI and other intelligent means to dynamically monitor network quality, load and business, and also requires the cooperation of energy saving methods to maximize energy saving and cost reduction and efficiency improvement.
