WiMAX系统一种改进的QoS架构

An improved QoS architecture for WiMAX system

针对WiMAX系统原有QoS机制的不足,提出一种改进的QoS架构。改进的QoS架构对业务分类模块、接纳控制模块和SS上行调度模块等系统尚未定义的部分进行了完善,详细阐述了各功能模块的作用和相互关系。改进的QoS架构使系统更加智能化,可优先满足对时延有严格要求的业务连接,以满足QoS要求,提高系统资源利用率。

Aiming at the shortcomings of the original QoS mechanism in Wi MAX system, this paper puts forward an improved QoS architecture. The improved QoS architecture perfects the business classification module, admission control module and the SS uplink scheduling module, which are not defined in original QoS mechanism. The role and relationship between the various functional modules are elaborated in detail. The improved QoS architecture makes the system more intelligent, can preferentially meet business connection that has strict requirements of delay, meet the requirements of QoS, and improves the utilization of system resource.
