摘要
为了减少移动终端的功率消耗,在移动通信系统中引入了不连续接收(discontinuous reception,DRX)省电机制。分析了在TD-LTE系统中DRX机制的因素和特征。通过搭建DRX模型来实现增强型的DRX机制。基于分析模型,研究了DRX的省电因素。最后,通过对因素的优先性选择实现终端的节能,同时保证用户的优良体验。
In order to reduce the power consumption of battery,this paper introduced a kind of power saving mechanism in mobile communication,named DRX. It discussed and showed DRX parameters and features in TD-LTE. By establishing TDLTE DRX model to the enhance DRX mechanism. Based on the analytical model,this paper investigated the DRX parameters and improved the power saving performance. Finally,the proper choice of these parameters （ short DRX timer,long DRX timer,inactivity timer and on duration timer） allowed for reducing power consumption in time and keeping the best user experience.
