摘　　要：为了有效地解决无线通信网络在宽带业务不断增加时产生的拥塞问题,提出了将区分服务模型应用于第三代移动通信网络以满足不同业务对QoS的需求。详细分析了区分服务模型的关键技术以及区分服务模型的系统结构,将区分服务模型和第三代移动通信分组域核心网系统结合起来,设计了支持QoS的第三代移动分组域核心网络。实验表明提出的模型较好地解决了第三代移动网络分组域核心网的QoS问题,提高了对不同业务的服务质量。In order to solve the network congestion prolem effectively when the broadband services in wireless communication increase, the application of DiffServ Model to 3G mobile network is proposed to meet the requirements of different services. The technologies and system architecture of differentiated services QoS are analyzed in detail. To combine DiffServ with 3G mobile packet system, the 3G mobile packet network system in support of QoS is designed. The experimental results show that the proposed model could fairly solve the QoS problem of core network for 3G mobile communicaiton system and improve the service quality to different services.
