Problems solved by technology

Since only PSTN emulation services can be realized without considering the access of ISDN users, at the same time, from the perspective of the architecture diagram itself, although it is described that GW and MG can access ISDN users on the access side, the interface P1 to the network ( H.248 signaling), H.248 signaling is used for media gateway control, but there is no way to transfer the DSS1 signaling information used by ISDN users, and the GM interface is a SIP (abbreviation for Session Initiation Protocol, Session Initiation Protocol) protocol interface, It is also impossible to completely transmit ISDN user signaling information, so the solution does not support ISDN user access in terms of architecture, and the interface that the solution itself does not have is used to transmit ISDN signaling information, so ISDN services cannot be simulated.

Embodiment Construction

[0040] In conjunction with FIG. 2, a specific embodiment of the system and method of the present invention is illustrated. In the schematic diagram of the network system based on the IMS (abbreviation of IP Multimedia Subsystem, IP Multimedia Core Network Subsystem) architecture shown in FIG. 2, except Except for the four network entities of ISDN terminal equipment 201 (ISDN TE), iAGCF 203, iAGF202, and iAS204 and their interfaces, other network entities and related interfaces are the same as ETSI (abbreviation of European Telecommunications Standards Institute, European Telecommunications Standards Institute) ) The IMS definition defined in TISPAN is the same.

[0041] Figure 2 shows the included IMS, Call Session Control Function (Call Session Control Function, abbreviated as CSCF), I-CSCF is the abbreviation of Interrogating-CSCF, which means querying CSC, and S-CSCF is the abbreviation of Serving CSCF, which means serving CSCF , block 205 is querying / serving CSCF; I / S-CSCF...

Abstract

Based on IMS-framework grouping network, the disclosed ISDN business system in grouping network adds an ISDN terminal device, an iAGF accessing ISDN device through S / T interface, an iAGCF to manage and control the iAGF, and an iAS. It accesses ISDN user into IMS domain, uses the iAS and iAGCF for basic ISDN business and supplementary service, and promotes the development from ISDN network to smooth IMS network.

Description

technical field [0001] The present invention relates to network compatibility technology, in particular to a system and method for implementing integrated services digital network services through packet network emulation, and more specifically, to a system and method for implementing integrated services digital network (ISDN) services in a packet network based on IMS architecture System and method for realizing integrated services digital network services in Internet protocol multimedia core network subsystem (IMS) Background technique [0002] IMS (abbreviation of IP Multimedia Subsystem, Internet Protocol Multimedia Subsystem), as a network based on packet switching, is a subsystem proposed by 3GPP in Release 5 to support IP multimedia services. Its core feature is that it adopts SIP protocol and has nothing to do with access. IMS is a multimedia control / call control platform on the PS domain, supports conversational and non-session multimedia services, and provides a ge...
