| 摘 要： | 彩铃业务作为一种重要的增值任务,已经在现有固定和移动网络得到了广泛的应用。随着IP多媒体子系统(IMS,IP Multimedia Subsystem)的引入,彩铃业务的多媒体特性得到了极大的增强,势必会在未来的业务发展中成为极具吸引力和商业价值的增值业务之一。文中通过对会话初始协议(SIP,Session Initial Protocol)进行研究,设计并实现了三种多媒体彩铃业务的实现方案,包括系统设计和信令流程,并对技术实现关键点及方案特点进行了分析。

| Abstract: | Ring-back-tone service is widely used in the current telecom network.With the introduction of IP Multimedia Subsystem(IMS),the types of early media are strongly expanded,Multimedia ring-back-tone service becomes one of the most attractive value-added services.Considering SIP ability in supporting the early media,three solutions to multimedia ring-back-tone based on SIP are proposed for IMS.Meanwhile the traits related to the solutions are also given in this paper. |
