摘　　要：研究了无线接入网络环境下自适应公平调度模型,讨论了服务区分的必要性和无线网络调度补偿方法,设计了一种二级结构的服务区分自适应公平调度算法,算法能够区分不同服务类型,公平分配网络资源。对于链路造成的暂时性服务中断给予了多级服务补偿,并通过分组级的公平资源分配,保障服务质量和流队列的平滑降级。The fair scheduling model in wireless/mobile environment was studied, The necessity of DiffServe and com- pensatory scheduling mechanism was chorused, a two-level wireless fair scheduling algorithm （TWFS） which differentiates service types and allocates network resources fairly was devised. As for the contemporary service intermittence due to link failure, service compensations was made at link level and packet level. The packet level fair resource allocation ensured the graceful degradation of service quality.
