摘　　要：TD-LTE(时分同步码分多址-长期演进)系统业务呈非对称状态,对下行数据率的要求要超过上行数据率,因而对系统信道上下行资源分配的要求更为严格。文章利用中断概率接纳控制算法对系统信道资源进行了智能动态分配,通过系统仿真证明了该策略能够灵活分配系统时隙资源。TD-LTE system services are asymmetrically offered and the requirement on downlink data rate exceeds that on uplink data rate.Therefore,more rigorous requirements are placed on the resource allocation of the system uplink and downlink channels.In this paper,intelligent dynamic resource allocation is performed for the system channel resources by using the outage probability-based call admission control algorithm.System simulation proves that the system time slot resources can be flexibly allocated by using this strategy.

关 键 词：中断概率 接纳控制策略 信道资源
