Method for providing fixed network intelligent business and system thereof

Abstract

A method and system for providing a subscriber with an intelligent service provides the subscriber of an IP Multimedia Subsystem (IMS) domain with special intelligent services of multiple intelligent platforms or convergent services. In the present invention an IP Multimedia Service Switching Function (IM-SSF) that supports an intelligent control protocol other than a Customized Application for Mobile network Enhanced Logic (CAMEL) Application Part (CAP) protocol is added into the IMS. The IM-SSF triggers the intelligent services through the protocol other than CAP to a Service Control Function (SCF) of corresponding intelligent platform according to obtained subscription information upon receipt of a session establish request related to a served subscriber; the subscription information can be pre-configured in the IM-SSF, or downloaded by the IM-SSF from a Home Subscriber Server (HSS) of the subscriber.

Description

technical field [0001] The invention relates to the triggering technology of intelligent network services, in particular to the technology of providing fixed network intelligent services to IMS users. Background technique [0002] The concept of intelligent network was proposed by Bell Communications Corporation of the United States and American Technology Corporation in 1984, and was standardized by the International Telephone and Telegraph Consultative Committee (CONSULTATIVE COMMITTEE FORINTERNATIONAL TELEPHONE AND TELEGRAPHY, referred to as "CCITT") in 1992. It is a system that can quickly, conveniently, flexibly, economically and effectively generate and realize various new services. The goal of this system is to serve all communication networks, both for existing fixed networks such as Public Switched Telephone Network (PSTN for short), Integrated Services Digital Network (Integrated Services Digital Network, ISDN for short) ) services, and also serve mobile communica...

Problems solved by technology

[0013] In addition, it is worth noting that in terms of the triggering method of the existing fixed-line intelligent services, although the fixed-line intelligent platform is based on the definition of IN CS2, due to the limitation of the fixed-line call control process, the intelligent services can only be dialed according to the special number or prefix of the user. Or trigger according to the special attribute flag in the user data scattered in each switch

[0014] In practical application, the above solution has the following problems: Although IM-SSF can provide mapping from IMS SIP to circuit domain CAP and SSP triggering capability, so that IMS users can seamlessly inherit WCDMA circuit domain intelligent services, it cannot realize the integration with fixed network Intelligent platform cooperation, that is to say, cannot provide fixed-line intelligent platform-specific services or integrated services for IMS domain users

[0015] In addition, the intelligent services of the fixed network can only be triggered according to the user dialing a special number or prefix. This method of triggering based on the special attribute flags in the user data scattered in each switch is limited by the network entity capabilities of data storage, and Lack of standardization; again, this single trigger method also affects user service experience

The defect of the trigger mechanism affects the development of fixed network smart services to a certain extent

[0016] The main reason for this situation is that IM-SSF can only provide the mapping from IMS SIP to WCDMA circuit domain CAP; while in the fixed network intelligent platform, the protocol between SCP and SSP is INAP

Although CAP is based on INAP, there are always differences between the two. Therefore, the difference in interface protocols prevents IM-SSF from triggering fixed network intelligent services.
