针对长期演进(LTE)系统恒功率休眠模式中存在的低业务、高功耗等缺点,提出一种变功率休眠算法.该算法可根据终端业务要求,动态改变休眠周期,以提高终端的待机时间,并以该算法为基础,探讨休眠状态终端的平均响应时间和平均功耗等问题.仿真实验表明,与恒功率休眠算法相比,该变功率休眠算法可以减少功耗6%-12%.%Aiming at the demerits of the lower business and higher power consumption, etc., in constant power dormancy mode of the Long Term Evolution(LTE) system. This paper proposes a variation of power dormancy algorithm at first, which can dynamically change the dormancy period according to the demands of terminal business, promote the standby time of terminal, then, discusses several problems about the average response time and average consumption of the terminal in the dormant state under this algorithm. Simulation experiments show that, compared with constant power dormancy algorithm, the energy consumption can be reduced by 6%~12% in this algorithm.
