IMS IP Multimedia Subsystem IP多媒体子系统 S-CSCF 业务会话控制功能Serving Call Session Control Function 服务ＣＳＣＦ执行会话控制功能。它可以根据网络运营商的需要，维持会话状态信息。在同一个运营商的网络中，不同的Ｓ－ＣＳＣＦ可以有不同的功能。
IMS即IP Multimedia Subsystem （IP多媒体子系统），是3GPP在R5版 本中提出的、对IP多媒体业务进行控 制的网络核心层逻辑功能实体的总称， 是基于SIP的通用平台。IMS提供实时 和非实时的IP多媒体业务，支持多种 接入类型，包括G S M 、W C D M A 、 CDMA2000、WLAN 和固定宽带接 入。IMS被认为是下一代网络的核心 技术，也是解决移动与固网融合，引入 语音、数据、视频三重融合等差异化业 务的重要方式。
The IP Multimedia Subsystem (IMS) is the foundation architecture for the next generation of mobile phones, wireless-enabled PDAs, PCs, and so on, delivering multimedia content (audio, video, text, etc.) over all types of networks. It is essential fo
Introduction Formally, the IP Multimedia Subsystem (IMS) is defined as: “... a new core network ‘domain’ (i.e. a new mobile network infrastructure composed of a number of discreet elements).”
This is a two day in-depth technical course intended to provide students a sound understanding of the framework, architecture, network element function, protocols and procedures associated with the IP Multimedia Subsystem (IMS) and IMS-based applica
