Patent ID: 8626158

Claim:
A method for providing a subscriber of an Internet Protocol (IP) Multimedia Subsystem (IMS) with an intelligent service, wherein, the IMS comprises an IP Multimedia Service Switching Function (IM-SSF) entity supporting an intelligent control protocol other than a Customized Application for Mobile network Enhanced Logic (CAMEL) Application Part (CAP) protocol, the method comprises: selecting, by the IM-SSF, an intelligent control protocol upon receiving a session establish request related to the subscriber; triggering, by the IM-SSF the intelligent service to a Service Control Function (SCF) entity of a corresponding intelligent platform through the selected intelligent control protocol when the selected intelligent control protocol is an intelligent control protocol other than the CAP protocol, wherein the manner for selecting an intelligent control protocol is one of the following: Manner A: selecting an intelligent control protocol according to an extended CAMEL Subscription Information (CSI) type, which is defined as dedicated to a SCF supporting the intelligent control protocol other than the CAP protocol, by performing a matching evaluation of the extended CSI type at a Detection Point (DP); Manner B: selecting an intelligent control protocol according to a service key in a standard CSI associated with a match relationship between the service key and an intelligent control protocol configured in the IM-SSF in advance; Manner C: selecting an intelligent control protocol according to a SCF address in a standard CSI associated with a match relationship between the SCF address and an intelligent control protocol configured in the IM-SSF in advance; or Manner D: selecting an intelligent control protocol according to the settings in the IM-SSF that only one protocol is supported in a period of time.
