摘　　要：针对TD-HSPA系统现有快速动态信道分配算法的数据业务中没有优先级次序的不足,提出了一种基于移动互联网的快速动态信道分配算法.该算法依据数据业务传输时延敏感度、速率高低等设定不同的优先级,以及部分资源共享的方法,使可移动边界动态信道分配策略更为灵活.仿真结果表明,该算法保证了优先服务实时性数据用户、高速率数据用户,提高了共享资源利用率.In order to eliminate the disadvantages of current fast dynamic channel allocation algorithm with no priority of data service in TD-HSPA system,it proposes a new dynamic channel allocation algorithm,based on the Mobile Internet.In the proposed algorithm,different priorities were set through data traffic transmission delay sensitivity and rate,and the method of resource sharing was proposed,which made movable boundary dynamic channel allocation strategy more flexible.Simulation results show that the algorithm ensures to serve real-time and high rate data users first,improving the utilization efficiency of shared resources.
