Renewable energy supply base station access selection method and system

Abstract

The invention discloses a renewable energy supply base station access selection method and a renewable energy supply base station access selection system. The method comprises the following steps of: acquiring information which affects candidate base station access selection in a renewable energy supply wireless communication network; calculating optimal energy efficiency, which can be reached by a link, and a link energy consumption characteristic when a terminal is accessed to a candidate base station according to the received information which affects the candidate base station access selection; initializing a terminal set accessed to each candidate base station, judging whether a network with energy balance is an initial access terminal or not and sustainably determining an access scheme according to network energy with energy balance; and judging whether a non-accessed terminal is available or not, updating the terminal set accessed to each candidate base station to continuously perform access selection if the non-accessed terminal is available and otherwise finishing selection. According to the method and the system, energy sustainability and balance of all base stations in the entire network are improved, the integral energy consumption of the network is minimized, and the service time of the network is prolonged.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for access selection of base stations powered by renewable energy. Background technique [0002] In today's world, the issue of environment and development has become one of the core issues concerned by the international community. With the rapid growth of wireless communication network coverage and data service demand, wireless communication has also become the fastest growing field of energy consumption in the information communication industry. From two aspects of economic benefits and environmental protection, energy saving is one of the important goals in wireless communication network management. There have been many studies on green wireless communication networks at home and abroad, mainly focusing on technologies to reduce energy consumption of wireless communication networks and improve energy utilization efficiency, and to explore th...

AI Technical Summary

Problems solved by technology

[0009] To sum up, the disadvantage of the existing technology is that it only conducts research on base stations powered by a fixed power grid. The power supply of the fixed power grid is stable, but the power supply of the power grid has problems such as non-renewable energy and large emissions of greenhouse gases such as carbon dioxide.
