摘要: 在通用移动通信系统(UMTS)基于策略的服务质量(QoS)机制的基础上,提出一种面向下一代移动网络的端到端分层QoS 架构。定义了涵盖无线接入网络的增强策略管理组件,并引入了分层策略模型和通用开放策略服务(COPS)协议扩展以完成自适应网络资源配置和QoS协商。对该架构实例性能的仿真结果表明,该架构既保障了会话的QoS要求,更利于网络间QoS参数的智能配置和自适应协商,最终在全网范围内保障业务的端到端服务质量。

Abstract: After an introduction of the policy-based quality of service(QoS) mechanisms ofuniversal mobile telecommunication system(UMTS), a new policy-based QoS Framework was proposed for the next generation mobile networks. Enhanced policy management components were defined that cover the radio access networks. Hierarchicalpolicy models with common open policy service(COPS) extensions were introduced to achieve adaptive configuration of network resources and QoS negotiation. A specificcase of this policy-based QoS framework was simulated. The performance resultsshow that the required quality of service of the session can be guaranteed. It also benifits the intelligent configuration and adaptive negotiation of the QoS parameters among networks, and eventually the end-to-end QoS can be well guarenteed in the entire networks.

Key words: :policy-based, quality of service, end to end, IP multimedia subsystem
