对未来无线网络服务进行分析,反映出用户体验质量(QoE)将成为未来无线网络服务的主要目标。通过对LTEA中不同业务的QoE研究以及系统公平性分析,以用户QoE作为资源调度的分配依据,基于经典比例公平算法提出一种基于QoE的比例公平调度算法(QoE-PF算法),提升系统用户QoE的公平性。仿真结果表明,QoE-PF算法具有良好的用户QoE公平性。
Future wireless network services were analyzed,and the fact that the quality of experience(QoE)of users was going to be the main target of future wireless network services was reviewed.In LTE-A,through the QoE fairness analysis of different businesses and systems,the users' QoEs were used as the basis for resource allocation,and a QoE proportional fair scheduling algorithm(QoE-PF)based on the classical proportional fair algorithm was proposed,which improved the users' QoE fairness.Simulation results show that the QoE-PF algorithm has good QoE fairness.
