摘要:
针对目前非连续接收(DRX)机制单一的周期配置难以适应4G网络环境下多业务并发的问题,提出了一种基于马尔科夫链的自适应DRX优化机制.首先,基于数据业务间的时间相关性建立马尔科夫链模型,预测后续时刻的数据业务类型;然后,根据预测结果和物理下行控制信道(PDCCH)的监听状态来综合调整DRX周期时长.仿真结果表明,相比于固定周期的DRX机制,自适应DRX优化机制能够在不增加过多时延的条件下有效降低终端能耗,同时实现了4G网络环境下不同数据业务类型的自适应DRX参数配置.
Abstract:
Aiming at the problem that the single cycle configuration of the current discontinuous reception(DRX)mechanism is difficult to adapt to the multi-service concurrent in 4G network environment, an adaptive DRX optimization mechanism based on the Markov chain is proposed. First, the Markov chain model is established based on the time correlation between data services, and the data service types at the subsequent time are predicted. Then, the DRX cycle length is adjusted according to the prediction results and the monitoring state of the physical downlink control channel(PDCCH). The simulation results show that, compared with the fixed cycle DRX mechanism, the adaptive DRX optimization mechanism can effectively reduce the energy consumption of the terminal without increasing too much delay time, and realize the adaptive DRX parameter configuration of different data services in 4G network environment.
