摘　　要：3G系统将以分组交换方式提供语音、数据、视频等具有不同QoS要求的多种业务 ,资源调度对保证系统服务质量和提高资源利用效率起关键作用 .本文提出了一种基于业务类型、当前待发送负荷以及剩余延时限的时间调度策略和基于资源优化的资源调度策略 ,并使无线链路的传输质量与业务的优先级水平一致 .Multiple services with different QoS requirements will be provided in 3G systems,Since packet switch will be adopted not only in the backbone but also on the air interface,radio resource scheduling plays a key role in guaranteeing system QoS and enhancing utilizing efficiency of radio resources.This paper proposes a service type,current payload and left over delay limit based time scheduling strategy and an optimizing resource based resource scheduling strategy,which also makes the wireless link transport quality comply with the traffic priority levels.Performances of the algorithm are evaluated through system level simulation.
