SIP的扩展在IMS QoS优化中的应用研究
Research on applications of SIP extension in IMS QoS optimization
摘要
基于SIP(会话初始协议)的IMS(IP多媒体子系统)的产生与发展, 使得固网与移动网络的融合成为可能。为这种新型的网络提供多媒体业务的QoS(服务质量)保障是一个关键问题。根据SIP的简单、易扩展性, 文章提出了一种利用SIP的扩展来改善IMS QoS的方案。
Abstract
The generation and development of the SIP-based IP Multimedia System (IMS) enable the convergence of fixed and mobile networks and it has become a crucial issue to provide QoS guarantee for the multimedia services of such a new type of network. In view of the simplification and easy extension of SIP, this paper presents a novel scheme for the improvement of IMS QoS by using SIP extension.
