下一代移动网络中非连续接收机制对移动互联网业务性能影响分析

摘要

The development of mobile Internet services require frequent signaling interactions between network and terminals, which causes the excessive waste of the UE energy consumption and wireless signaling resources. This paper focuses on the discontinuous reception (DRX) mechanism of the next generation mobile network in the 3GPP standards. The impact on DRX to the network performances of the typical mobile Internet services are analyzed in terms of energy consumption, packet delay and wireless signaling overhead. Furthermore, the optimization for the setting of the DRX parameters is discussed to improve the network performance.%移动互联网业务的发展引发了大量需要终端与网络间进行频繁交互的业务,产生了终端能量和无线信令资源消耗过度的问题.结合3GPP标准定义的下一代移动网络非连续接收(discontinuousreception,DRX)机制,从终端能耗、数据包延时、空口资源开销等角度出发,分析了DRX机制对典型移动互联网业务的网络性能影响,并对DRX机制的参数配置提出了优化建议.
