摘　　要：针对无线城域网(MAN:Metropolitan Area Network)对准入控制、流量控制、带宽调度算法问题,在分析IEEE 802.16 MAC(Media Access Control)协议的基础上,提出了一种具体的QoS(Quality of Service)架构以及死限制调度和余量调度相结合的上行调度算法,并对其进行了设计和测试。结果表明,该算法能对实时业务提供较好的支持,基本功能得到实现。As next generation communication technology, wireless MAN （Metropolitan Area Network） （IEEE 802. 16e） has put forward QoS （Quality of Service） for many services. IEEE 802. 16 standard is only specific the QoS service type, such as bandwidth request and allocation and so on, but some schedule arithmetic, ad- mittance dose not be researched. A new QoS architecture and uplink schedule algorithms that is deadline and surplus schedule arithmetic were proposed, and the design the uplink bandwidth schedule module was implemented, the result shows it can supply the real-time operations very well.
