摘　　要：针对LTE业务QoS特征多样化且应考虑业务付费等级的问题,提出了一种改进的比例公平调度算法。新算法引入不同业务的各QoS指标、付费等级作为参数,并根据各业务的具体QoS需求在各参数的不同加权配置下切换。仿真结果表明,新算法不但可以极大提高付费业务的各项QoS指标,还能让所有业务的QoS指标达到既定需求,更好地适应了LTE网络规划的要求。An improved proportional fair scheduling algorithm is proposed to solve the problem that QoS（Quality of Service） characteristics of LTE services is diversify and the service pay levels should be considered. This new algorithm takes the QoS indicators and pay levels of different services as parameters, and executes handover according to different weighting disposition of the parameters. The simulation result indicates that the new algorithm can not only enhance the QoS indicators of payment services but also make QoS indictors of all service meet requirement. It is more adapted to the requirements of LTE network planning.
