Abstract

The invention provides a method, a system and an internet protocol multimedia service switching function (IM-SSF) for the signaling interaction between an internet protocol multimedia subsystem (IMS) and an intelligent network, wherein the method comprises the following steps that: a serving call session control function (S-CSCF) of the IMS determines the intelligent service types according to an initial filter criteria (iFC) and notifies the intelligent service type to the IM-SSF of the IMS; the IM-SSF obtains a trigger list according to the intelligent service type; and the IM-SSF triggers calling and called intelligent service through a trigger indicated by the trigger list for carrying out the signaling interaction with a service control point (SCP) of the intelligent network. The corresponding calling and called intelligent service trigger is triggered through the IM-SSF of the IMS, and the signaling interaction between the IMS and the SCP of the intelligent network is realized.

Description

technical field [0001] The present invention relates to the field of IP multimedia system IMS, since it relates to a method for signaling interaction between IMS and intelligent network (IM) and an IP multimedia-service switching function entity (IM-SSF). Background technique [0002] Intelligent Network (IN) is a network architecture that generates and provides intelligent services quickly, economically, conveniently and effectively on a communication network. It is an additional network structure set up to provide users with new services on the basis of the original communication network. Common intelligent services include prepaid PPC services and called to pay FPC services. [0003] The CDMA network defines a wireless intelligent network protocol (Wireless Intelligent Network, WIN). Based on the WIN protocol, the CS domain-based CDMA network performs signaling interaction with the service control point SCP of the intelligent network through its mobile switching center ...
