摘要: WCDMA系统混合业务下的资源调度算法要区分业务以保证用户的服务质量(QoS)。基于此,在研究最大加权延时优先算法(M-LWDF)的基础上通过引入QoS监测机制提出一种保证混合业务服务质量的资源调度算法,在业务调度中同时考虑时延优先级和吞吐量优先级,并采用传输时延保证的资源分配准则。仿真结果表明,该算法在时延和吞吐量水平上要优于已有的调度算法。

Abstract: The resource schedule algorithms in hybrid-traffic WCDMA system must differentiate the service to guarantee the demand of QoS. Therefore, on the research of Modified Largest Weighted Delay First algorithm(M-LWDF), a hybrid-services resource schedule algorithm which guarantees the demand of QoS is proposed with the usage of QoS monitoring mechanism. It considers both the delay priority and throughput priority during the service schedule period, and it guarantees the transmission time delay during the resource allocation period. Simulation results show that the algorithm is superior to the existing schedule algorithms in the level of delay and throughput.

Key words: Quality of Service(QoS), resource schedule, time delay, throughput
