随着LT E网络的大规模建设，运营商面临着空前激烈的竞争环境，这导致无线接入网络的能源消耗问题变得日益严重。为降低LT E网络能耗现状，首先分析了LT E网络基站关断休眠、通道关断休眠、载频关断休眠、符号关断休眠、MBSFN子帧调整关断休眠和PSU关断休眠等技术的原理，随后对满足试验条件的技术进行现网测试分析，通过对比节能措施实施前后基站能耗、网络性能指标以及路测结果的差异，验证了措施的节能效果和对网络性能的影响。

With the large-scale construction of LTE network, operators are facing unprecedentedly fierce competition environment which results in increasingly severe issue of energy consumption of wireless access network. In order to reduce energy consumption of LTE network, the technical principles of shutdowns for LTE base station (BS), channel, carrier, sign, MBSFN sub-frame adjustment and PSU were analyzed in this paper ifrstly. Then, techniques which meet experimental conditions were tested and analyzed in existing network. The differences of BS energy consumption, network performance indicators and road tests after implementation of energy conservation veriifed that the energy-saving effect and inlfuence on network performance.
