摘要： 为减少移动终端的功率消耗，IEEE 802.16e提出空闲模式的节能机制。根据空闲模式的机制，建立带启动期的多重休假Geom/G/1队列模型。使用嵌入Markov链方法，推导出模型性能指标，得到IEEE 802.16e中空闲模式节能方案中相应的性能指标。通过数值例子和仿真结果，进一步比较了性能指标和系统配置参数之间的关系。

Abstract: In order to reduce the power consumption, IEEE 802.16e proposes an idle mode energy saving mechanism. According to the operation mechanism of the idle mode, a Geom/G/1 queue with setup time and multiple vacations is built. The performance measures of the queue model are obtained by using an embedded Markov chain method. Some performance measures are derived for idle mode in IEEE 802.16e. The dependency relationships between the system performance measures and the system parameters are compared by numerical examples and simulation results.
