摘　　要：在第三代移动通信系统中用户终端(简称为UE)在空闲模式下的能源消耗是一个很重要的研究方面。文中基于这一研究以及为了克服传统方法中无论服务小区的质量如何,DSP总是要周期性地向协议栈的RRC发送更新的测量值,周期性地"唤醒"ARM的弊端,提出了一种在服务小区通信质量保持良好的情况下,DSP不必唤醒ARM上传测量值,以降低UE在空闲模式下能源消耗的新方法。此方法已经证明具有很高的实用和参考价值。In the 3rd mobile communication systems, energy consumption of the user terminals （referred to as VE） in idle mode is a hot research topic. Based on this research and for overcoming the malpractice of the traditional method that without reguard to the quality of service area, DSP has to periodically send the updated measurements to the RRC protocol stack and ＂wake up＂ ARM, a new method for lowering energy consumption of VE in idle mode is proposed, with which the DSP does not need to ＂wake up＂ ARM for upload measurement under the circumstances that the communication quality in the service area keeps in good condition. This method has been verified to be of practical and reference value.
