Problems solved by technology

Although the IMS can realize the independence of the access network, at present, the IMS only supports the mobile access modes of the 2nd Generation (hereinafter referred to as 2G) and the 3rd Generation (hereinafter referred to as 3G), It still cannot support fixed access mode. Under the development trend of network convergence, some working organizations, operators and eq...

Embodiment Construction

[0026] The present invention is a method and system framework for supporting the PSTN / ISDN simulation access mode of traditional terminals under the framework of IMS system and realizing the fusion of mobile and fixed networks. This system is mainly composed of network element entities such as CSCF, MGCF, BGCF, HSS and SLF under the current IMS architecture, wireless access network and its mobile terminals, EGCF supporting PSTN / ISDN emulation, corresponding gateways and traditional PSTN / ISDN fixed terminal components, such as figure 2 As shown, the communication between the mobile user and the traditional PSTN / ISDN fixed terminal user can be realized through the gateway device.

[0027] image 3Shown is a preferred embodiment of the present invention based on the PSTN / ISDN emulated fixed access of traditional terminals in a WCDMA network under the 3GPP architecture. Mainly composed of HSS (101), EGCF (200), inquiry call session controller I-CSCF (201), service call session...

Abstract

The present invention relates to a method for combining PSTN/ISDN emulating of the traditional terminals in an IMS system structure and to a system for implementing the said method. The present invention adds emulating gateway control function (EGCF) in an IMS system structure that can implement 3G terminal user multi-media service. The present invention also adds gateway GW accessing traditionalPSTN/ISDN terminals and traditional terminal equipment, accordingly, it can provide traditional PSTN/ISDN terminal user access in the IP multi-media sub-system and can implement the function of PSTN/ISDN emulation. The present invention provides supports to fixed access and mobile access in an IMS system structure, it implements the combination between fixed network and mobile network, and especially, it is suitable for supporting both mixed and mobile full-service field at the same time.

Description

technical field [0001] The present invention relates to a method for mutual integration of switching systems in the telecommunications field and a system for realizing the method, in particular to an IP Multimedia Subsystem (IP Multimedia' Subsystem) (hereinafter referred to as IMS) framework, which integrates traditional terminals into a common A method for simulating a Public Switched Telephone Network / Integrated Services Digital Network (hereinafter referred to as PSTN / ISDN) and a system for realizing the method. Background technique [0002] The switching systems in the current telecommunications field are basically concentrated in fixed network switching systems and mobile network switching systems. They all appear as an independent system in the operating environment, either only supporting fixed switching networks or only supporting mobile switching networks. . At present, no matter in China or other countries, many operators are full-service operators. They operate ...
