摘要 提出一种利用DRX(discontinuous reception)降低UE(user equipment)功耗的视频流调度方法,该方法在保证数据包时延要求的同时,减少了InactivityTimer的开启次数,增加了UE的休眠时间.仿真结果表明,相比已有的DRX机制下的实时业务调度方法,该方法可以在丢包率相同的情况下,显著降低UE的功耗. A scheduling method for saving UE＇s power by using DRX for the video streaming is proposed in this paper. The times of starting/restarting I-Timer can be reduced while the delay requirement of a packet is guaranteed, which increases the sleeping time of a UE. Simulation results show that this method can significantly reduce the power consumption of a UE with the same packet loss rate.
