摘　　要：为提高密集移动终端商圈区域的终端服务质量,提出一种基于业务驱动资源预留的密集移动终端网络接入方法。根据网络属性、终端运动预测轨迹和业务类型,为高优先级业务终端预留资源量,在尽可能少牺牲低优先级业务服务质量的前提下,使高优先级业务终端获得稳定可靠的网络服务,并通过时间触发公平机制保障低优先级业务终端的网络接入资源。仿真结果表明,该方法不仅能够保障高优先级业务移动终端在异构网络中的接入质量,提高网络资源利用率,而且可以降低热点高容量场景下低优先级业务终端的接入失败率,改善用户体验质量。In order to improve the Quality of Service(QoS) of terminal in the area of dense mobile terminal business district,a network access method for dense mobile terminal network based on business-driven resource reservation is proposed.It reserves resources for terminals with high-priority business based on the attributes of networks,the forecasted motion trajectory of terminals and the types of business.Under the premise of minimizing the sacrifice of QoS of the low-priority service,it ensures high-priority business terminals get a smooth and reliable network service,and ensures network access resources for terminals with low-priority business by using time-triggered fairness mechanism.Simulation results show that,this method can not only ensure the access quality of mobile terminals with high-priority business in heterogeneous network and improve the utilization of network resources,but also reduce the access failure rate of low-priority business terminals in hot-spot high-capacity scenarios.What’s more,it can improve the users’Quality of Experience(QoE).
