软实时服务与绿色通信

摘要

结合"绿色通信"的需求,具体阐述了宽带移动业务软实时服务中的绿色通信思想,包括软实时服务中的"以延时换能耗"的设计理念,以及如何通过阈值限定来达到延迟和能耗的折中;并且介绍了一种适用于软实时业务模式的带闭环反馈的功率控制算法,对基站能耗进行了优化.%The concept of "Green Communications" in broadband mobile soft real-time communication is discussed. The problems of how soft real-time service can save energy with delay and how to use threshold to have a balance between delay and energy are addressed. A power control algorithm, which is applicable to soft real-time service model, is introduced to optimize the power consumption of base stations.
