摘要 建立了基于门限策略的双队列单服务台有限缓存包级休假排队模型IBP+MMBP/Geo/1/K。针对到达分布不同的两种业务各自的特点来定义休假策略,将H2H(Human to human)业务的休假期等效为M2M(Machine to machine)业务的服务期。为了寻求统一的标准来评价休假策略,定义了一个评价业务QoS的效能函数E。同时,研究了不同条件下的M2M业务对休假策略的影响。最后,通过仿真给出各种情况下系统各项性能指标以及效能函数的变化趋势,该研究结果可以用来指导无线资源分配和业务配置等问题。 A double-queue single-server and limited-cache packet-level vacation queuing model, IBP+ MMBP/Geo/1/K, with threshold was established. According to the respective features of different services, which have various arrival distributions to define vacation strategies, the vacation time of H2H service is equated to the busy time of M2M service. In order to seek unified standards to evaluate the vacation strategies, a performance function E to evaluate the Quality of Service (QoS) of different services was defined. At the same time, the influences of different M2M services on the vacation strategies were also studied. Finally, various performance indicators and the change trend of the performance function of the system were given through simulation. The results of this study can be used to guide the radio resource management and the service configuration problems.
