Embodiment Construction

[0091] The core of the present invention is to provide a system and method for using CS to carry services in IMS, that is, to provide a specific implementation scheme that meets the relevant requirements of 3GPP TS 23.899, wherein the user roaming situation involved in the process of using CS to carry real-time services Specific solutions are given for the route detour, charging association between CS domain and IMS domain, non-standard terminal access, and corresponding processing methods in case of abnormal CS bearer.

[0092] The system of the present invention is as image 3 As shown, it mainly includes: an IMS TM (IMS terminal module) that implements the CBCF function, a CS TM (CS terminal module) that implements the CBOF function, a CS domain call control entity, and an interworking gateway between the CS domain and the IMS domain that implements the CBTF function; among them, The CS domain call control entity (such as image 3 MSC) and CS domain and IMS domain interwor...

Abstract

The invention relates to a system for utilizing the CS to carry service in the IMS and its relative method. The invention divides the terminal that utilizing CS to carry service in the IMS into two parts of IMS terminal modular and CS terminal modular whose interface alternation between them; building the process that the CS terminal modular via the control of IMS terminal modular alternates and completes the CS carrying with the CS region calling control entity and the interconnection gateways of CS and IMS regions; and via the inter-control between the IMS terminal modular, the interconnection gateways and the two sections of IMS conversion between terminal users, utilizing said CS carrying into IMS service, therefore, the built CS carrying can be used to transmit the medium flow which demands higher real-time property in the IMS service. In addition, the invention also provides a technique method for utilizing the CS to carry service in the IMS as well as the method for avoiding the route bypass and charging association of CS region and abnormal process.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a system and method for carrying services by circuit switching in an IP multimedia subsystem. Background technique [0002] With the development of mobile communication technology, people are no longer satisfied with a single voice communication method, but need a new multimedia communication method. This multimedia communication is not only simple video and audio communication, but also includes instant messaging, same-site browsing, collaborative Work, streaming media and other business communications, especially the integration of new communication methods and traditional voice services. Based on the trend of Internet and telecommunications network integration, various standardization organizations have proposed the concept of next-generation network, and introduced the IMS (IP Multimedia Subsystem) of the all-IP service network architecture on the basis of the p...
