Dormancy control equipment for hybrid energy powered mobile communication base station

Abstract

The invention provides dormancy control equipment for a hybrid energy powered mobile communication base station. The control equipment comprises a controller and a storage device, wherein the storagedevice stores the following instruction steps loaded and run by the controller: calculating a broadband constraint condition and an energy constraint condition when the base station enters a dormant state; counting down by various non-dormant base stations according to respective energy virtual clocks, and when the energy virtual clocks of the non-dormant base stations are zero, judging whether the non-dormant base stations meet the energy constraint condition or not, and if yes, then sending a dormancy request to an adjacent non-dormant base station; and judging whether the non-dormant base station which receives the dormancy request meets the broadband constraint condition or not, if yes, then replying confirmation information of agreeing to be dormant to the non-dormant base station, after confirming the information by the non-dormant base station, switching the service to the adjacent non-dormant base station by the non-dormant base station, and entering the dormant state by the non-dormant base station. According to the dormancy control equipment for the hybrid energy powered mobile communication base station provided by the invention, on the basis of ensuring the communication service quality of a terminal, the purposes of network energy saving and emission reduction is realized.

Description

technical field [0001] The invention relates to the technical field of green mobile communication and the field of new energy, in particular to a dormancy method for a base station of a mobile communication network powered by mixed energy. Background technique [0002] In order to meet the rapid growth of mobile data traffic, the coverage width and depth of mobile communication networks are continuously upgraded, and the deployment density of base stations is getting higher and higher, which will bring about a sharp increase in network energy consumption and carbon emissions. However, solar energy has the characteristics of wide distribution and no carbon emissions in the power supply process, and introducing it into mobile communication networks is considered an effective means to reduce network energy consumption. [0003] "Hybrid Energy powered cellular Networks (HybE-Net)" refers to a mobile communication network whose energy supply includes both solar energy and mains p...

Problems solved by technology

However, in HybE-Net, considering that each base station has different renewable energy collection capabilities, the traditional dormancy strategy based only on load change characteristics can no longer solve the dormancy problem of base stations in HybE-Net, that is, HybE -The base station sleep strategy in Net not only needs to consider the impact of network load on it, but also needs to consider the limitations of the energy status of renewable energy sources in each base station

However, the existing research on HybE-Net-oriented base station dormancy methods only uses a simple energy statistical model to model the balance between renewable energy energy supply and energy consumption in HybE-Net, and lacks the power of base station in renewable energy. To understand the energy flow behavior during the power supply process, the energy state of the base station and its dynamic change characteristics have not yet been analyzed
