Problems solved by technology

In a CDMA network, the relationship between the IMS domain and the circuit domain is a substitute relationship, and the HSS and HLR are set up separately, and the HSS of the IMS domain does not store user access domain information, so winSCP cannot obtain the IMS domain through interaction with the HSS User's Roaming Information
[0020] It can be seen that if IM-SSF still uses the traditional circuit domain interface to interact with winSCP, it cannot provide roaming information of IMS domain users, and many intelligent services do not have user roaming information. Unable to realize, such as the aforementioned intelligent services such as PPC and ICS, these services cannot be provided to IMS domain users

Embodiment Construction

[0094] The core of the present invention is to extend the interface between the intelligent service control functional entity WinSCP and the IP multimedia subsystem switching functional entity IM-SSF. The interface provides the roaming information of IMS domain users to the corresponding WinSCP, so that WinSCP can perceive the information, so as to provide complete intelligent services to IMS domain users. The roaming information may be the real geographic location information of the user and / or the visited domain information of the entry point for the user to access the IMS domain. The manner in which the IM-SSF provides the roaming information of the IMS domain user to the WinSCP may be that the IM-SSF actively reports according to an intelligent trigger condition, or that the WinSCP requests the IM-SSF to report.

[0095] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in...

Abstract

The invention discloses a method and system for the conventional circuit field network to acquire user information in the field of IP multi-media subsystem. The method includes: IP multi-media subsystem exchange function entity IM-SSF acquires IP multi-media subsystem IMS field user roaming information; IP multi-media subsystem exchange functional entity provides acquired IMS field user roaming information to the intelligent service control functional entity SCP in the CDMA network. The system of invention includes: IP multi-media subsystem exchange functional entity IM-SSF and the intelligent service control functional entity SCP in the CDMA network; the IP multi-media subsystem exchange functional entity IM-SSF includes: IMS field user roaming information acquisition unit and IMS field user roaming information providing unit. The invention enables the SCP in the CDMA network to perceive the roaming characteristics of users in the IMS field, thus providing desirable intelligent services to users in the IMS field.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and a system for obtaining IMS domain user information by a circuit domain network. Background technique [0002] In order to quickly, conveniently, flexibly, economically and effectively generate and realize various new services, an intelligent network architecture is introduced in the traditional circuit domain, in which the fixed network defines the intelligent network application procedure INAP, GSM / WCDMA Broadband Code Division Multiple Access (CDMA) system introduces CAMEL (Customized Application of Mobile Network Enhanced Logic) to realize intelligent services, and CDMA mobile communication system defines a series of WIN (Wireless Intelligent Network) protocols. The above intelligent network architectures are all based on the traditional circuit domain. [0003] figure 1 It is the intelligent network architecture of CDMA traditional circuit domain, includ...
