METHOD AND SYSTEM FOR CIRCUIT DOMAIN TO PERCEIVE SESSION CHARGING INFORMATION OF IMS DOMAIN

摘要

A method and system for a circuit domain to perceive the session charging information of IMS domain, are used to solve the problem in the present art that the smart service control entity of the circuit domain can not perceive the session charging information of IMS domain. The method includes: the service switching function entity IM-SSF acquires the session charging information from the conversational control signaling of IMS domain received; and IM-SSF reports the session charging information received to the smart service control entity SCP. The system includes: HSS, SCP and S-CSCF, and includes IM-SSF connected with HSS, SCP and S-CSCF respectively, for acquiring the session charging information from the conversational control signaling of IMS domain received; the interface between IM-SSF and SCP, for reporting the session charging information received to SCP by IM-SSF.
