近年来,超三代移动通信系统的QoS体系结构已成为计算机网络领域和通信领域的一个研究热点.调研了相关的主要研究项目,通过对重点项目和国外该领域相关论文成果进行分析和比较,总结出未来B3G(beyond 3rd generation)系统QoS体系结构应是一种全IP的、层次化的、端到端的QoS体系结构,它应具有集成性、可管理性、可扩展性、自适应性和动态资源管理等特点.最后提出了B3G系统QoS体系结构的基本设计原则,并对未来工作进行了展望.

Recently, the QoS architecture in the beyond 3rd generation mobile communication system is becoming a hot topic in the area of computer networks and telecommunications. In this paper, the state-of-the-art QoS architectures are presented. By analyzing and comparing the key projects and papers published abroad, it is concluded that QoS architecture in B3G (beyond 3rd generation) system should be an all-IP, hierarchical and end-to-end framework. The main characteristics include scalability, controllable, self-adaptation and dynamic resource management. Finally, the design principals are proposed, and future works are summarized as well.
