摘要

策略网络(Policy-Based Networking, PBN)是一种方便网络管理和运行的新技术。本文研究了基于策略的QoS控制机制在3/sup / generation UMTS网络的IP多媒体子系统(IMS)中的应用。在UMTS中引入IMS是为了在移动网络中提供高质量的基于ip的多媒体服务。在介绍了PBN技术和支持端到端QoS控制的通用网络架构之后，显示了UMTS中指定的策略决策功能。分析了当前标准化状态的局限性，并提出了在单运营商和多运营商环境下提供基于策略的端到端QoS控制的扩展。

Policy based architecture for the UMTS multimedia domain

Policy-Based Networking (PBN) is a novel technology that facilitates the management and operation of networks. The paper reports on the application of Policy-Based mechanisms for QoS control in the IP Multimedia Subsystem (IMS) of the 3/sup rd/ generation UMTS networks. The IMS was introduced in UMTS to provide high quality IP-based Multimedia Services in Mobile Networks. After an introduction into PBN technology and a generic network architecture to support end-to-end QoS control, the Policy Decision Function as specified in UMTS is shown. The limitations of the current state of the standardization are explained and extensions to provide Policy-Based end-to-end QoS control in single and multi-operator environments are proposed.
