摘要:

WCDMA可为用户提供高速的多媒体业务,为了能够更好地提供多媒体业务,3GPP 标准化组织自R5版起在分组域上添加了IP多媒体子系统,利用IP多媒体子系统提供端到端的、有QoS保证的、基于IP的多媒体应用服务,其核心部分就是基于策略的QoS控制管理。本文将详细介绍IP多媒体子系统中基于策略的QoS管理体系结构,以及它是如何实现QoS保证的。

Abstract:

The third generation mobile system WCDMA provides high-speed applications and services.For offering better and easier management of IP multimedia services, 3GPP group defined the IP Multimedia subsystem over PS domain since release 6. IMS can support end-to-end, QoS guarranted, IP-based services. The key part is its policy-based QoS management function. In this article, the description of policy-based management for IMS is given. The policy-based QoS mechanism is analyzed.
