WCDMA IP多媒体子系统中基于策略的QoS管理

doi:10.3969/j.issn.1000-0801.2004.08.005

Abstract

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.

Key words: mobile communication, QoS, IP multimedia subsystem, policy-based management, WCDMA
