Embodiment Construction

[0087] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0088] image 3It is a flow chart of signaling interaction between the IMS and the intelligent network in this embodiment to realize the call origination of the PPC user.

[0089] S301 The user initiates a call and sends an initial INVITE message to the P-CSCF;

[0090] S302P-CSCF sends the initial INVITE message to S-CSCF;

[0091] S303S-CSCF judges that the calling user is a PPC user according to the initial filtering rule iFC, sends an initial INVITE message to the IM-SSF, and the initial INVITE message carries an identifier that the call is initiated by a PPC user;

Abstract

The present invention provides a method, system and IM-SSF for signaling interaction between the IMS and the intelligent network, wherein the method includes the service session control function entity (S-CSCF) of the IMS determining the intelligent service type, and notify the IP multimedia-service switching function entity (IM-SSF) of the IMS of the intelligent service type; IM-SSF obtains a trigger list according to the intelligent service type; IM-SSF indicates by the trigger list The trigger triggers the calling and called intelligent services, and performs signaling interaction with the service control point (SCP) of the intelligent network. The present invention triggers the corresponding calling and called intelligent service triggers through the functional entity IM-SSF of the IMS, and realizes the signaling interaction between the IMS and the SCP of the intelligent network.

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 ...
