W -CDMA(宽带码分多址 )是第三代移动通信系统空接技术中的首选技术 ,而动态资源配置作为一个框架为W -CDMA系统中的多媒体通信提供可靠的业务质量 ,动态资源配置监视通信变化量 ,以最优方式调节用户的传输功率 ,因此 ,动态资源配置在W -CDMA系统中得到广泛应用。由于单一队列动态资源配置方案无法满足综合业务需求 ,提出了一种新的具有优先队列的动态资源配置方案 ,并设计了一种基于优先队列的动态资源配置模型。分析表明 ,该方案能较好地满足W -CDMA通信系统的业务质量要求 W-CDMA (Wideband Code Division Multiple Access) is the preferred technology in the air-to-ground technology of the third generation mobile communication system, and dynamic resource allocation serves as a framework to provide reliable quality of service for multimedia communications in W-CDMA systems. Dynamic resource allocation Monitor the variation of communication, and adjust the user’s transmission power optimally. Therefore, dynamic resource allocation is widely used in W-CDMA system. Because single queue dynamic resource allocation scheme can not meet the demand of integrated services, a new dynamic resource allocation scheme with priority queue is proposed and a dynamic resource allocation model based on priority queue is designed. Analysis shows that this scheme can better meet the service quality requirements of W-CDMA communication system
