摘　　要：为了有效分析移动网络中移动站点的节能效率,研究了应用于移动宽带城域网的IEEE802.16e节能类型Ⅱ的工作原理,建立了一个具有两种休假机制,且在一种休假机制内可以传输少量数据帧的多重休假排队模型;构建了由能量节省率、系统切换率和数据帧平均响应时间等组成的指标体系,并给出了各个性能指标的解析表达式。通过数值示例,刻画了系统性能与系统参数的依赖关系,表明了该模型的可行性与有效性。To effectively analyze energy saving ratio of mobile station in mobile networks, the working principle of power saving class of type Ⅱ in IEEE 802.16e standard used for mobile broadband metropolitan area network is studied, a multiple vacation queue model with two kinds of vacation mechanism is built.In one of the vacations, a few data frames is transmitted.A measure system composed of energy saving ratio, system handover ratio and average response time of data frames is proposed, then the formula for these performance measures are given.Finally, numerical results are given to explain dependency relationships of the system measure on the system parameters and to demonstrate the feasibility and the effectiveness of the model presented.
