GPRS无线接入网的包排序方案能动态分配无线资源

Packet scheduling scheme able to dynamically allocate radio resources for GPRS radio access network

提出了通信排序机制,这个机制对于GPRS的一个移动台(MS)能够动态地分配无线资源,它是以无线链路的相互干扰和服务质量(QoS)规范为基础的。这个方案是当一个MS位于高干扰区域时,为了避免浪费带宽,对数据传输采用低的传输速率。当它在低干扰区域时,为了补偿服务丢失,将分配更多的带宽。

The authors present a traffic-scheduling framework that can dynamically allocate radio resources to a GPRS mobile station based on the interference levels of the radio links and quality of server specification of the MS. In this scheme, an MS uses a low transmission rate for data transfer when MS is within high interference region to avoid wasting bandwidth by transmitting data in the condition with high interference. The authors allocate more bandwidth to MS when it is within a low interference region in order to compensate the service loss of the MS.
