） Abstract： This paper first introduces the current service triggering mechanism in the IP Multimedia Subsystem (IMS), and then analyzes the defects of it
On the base of results we have gotten, we proposed a Policy based Service Triggering Framework (PSTF)
It can trigger service dynamically in real time according to the policy logic
PSTF not only can satisfy the needs of colorful IMS services, make the service triggering flexible and dynamical, but also can avoid the shortcomings of the current service triggering mechanism in the IMS, besides that, PSTF can be easily extended in detail according to the needs

使得业务的触发可以根据预置的策略逻辑进行实时的、动态的控制
使得业务触发具有灵活性和动态性
IP多媒体子系统
PSTF不仅满足现有的不断丰富的IMS业务需求
所有的这一切都有效地避免了现有的IMS业务触发方式的一些弊端
并给出一种基于策略的业务触发框架（Policy based Service Triggering Framework
