Research On Relations Of Traffic Load And Energy Consumption In LTE Base Station

With the rapid development of mobile communications and the large-scale use of wireless networks,the demand for user data services is in a blowout stage of growth.The increase in traffic also leads directly to the increase in energy consumption at the base station.For operators,the cost control of base station construction is the primary problem.At present,the actual construction of the base station is mainly based on the rated power consumption of the equipment,and the research on the energy consumption relationship is very scarce.A model of the relationship between business and energy consumption has been presented in this thesis.The relationship between the actual power consumption and the service characteristics of the base station has been analyzed in this thesis,and further applies it to a certain power supply construction scheme.Based on the analysis of business characteristics,this paper constructs a framework model that divides from the business characteristic to the physical resource block to the base station energy consumption.And then summarizes the base station data,combined with modeling ideas,gives a complete base station business energy analysis method.The model compares the energy consumption of different services to the finer degree of analysis,select the typical base station as the analysis target and compare the analysis result of the energy consumption model with the real-time measured power consumption data.And verify the feasibility of this calculation scheme.Which provides a good theoretical basis for the application of base station power supply in the later stage.Finally,uses the results of the analyzed energy consumption relationship to be applied to the project.At the beginning of the project,the base station of the project area covered by the project is based on the traffic volume and data flow and the service object.To determine the base station's backup time.Combined with the base station's business power relationship to obtain the base station's own load power consumption,through the actual operation of the device power and backup time division of the base station to the size of their respective battery capacity.After comparing with the traditional configuration scheme,the superiority of the scheme is confirmed,and the rational allocation of the base station power supply is realized.
