Embodiment Construction

[0023] The purpose of the present invention is to provide a method capable of realizing ISDN service station in NGN network. For this purpose, it is necessary to resolve the contradiction between the circuit access mode provided by the ISDN operator station and the packet access mode provided by the NGN network, and realize the conversion between the two communication modes. This conversion needs to rely on the media gateway to achieve. Combine below figure 1 with figure 2 Embodiments of the present invention will be described.

[0024] figure 1 with figure 2 The ISDN attendant console 1 shown can be a computer, on which an ISDN communication card is inserted, and conventional operating system software and attendant console terminal software run. The ISDN attendant console 1 is connected to the media gateway 2 through the ISDN 2B+D interface of the ISDN communication card, and the media gateway 2 is connected to the soft switch 3 through a packet network (such as an IP ...

Abstract

The invention provides a method for connecting an ISDN console to a next-generation network, including: when any party initiates a call between the ISDN console and a user in the next-generation network, the ISDN console and the user in the next-generation network initiate a call. The call control message is transmitted through the media gateway between the soft switches; the soft switch will control the media gateway to negotiate the media flow of the call, and after the media flow negotiation is completed, the media gateway will be used for the ISDN operator station and A call between the other parties on the call establishes a media streaming connection. According to the present invention, the traditional circuit-switched ISDN console can still be connected to the softswitch when the network is transformed into NGN, thereby protecting the existing investment. In addition, when the newly built NGN network does not have an IP network inside the user building, but has ordinary twisted pair lines, it can still access the circuit-based ISDN console to provide services to users.

Description

technical field [0001] The present invention relates to data communication services for Next Generation Networks (NGN). More specifically, it relates to a method for accessing an integrated services digital network (ISDN) attendant console in NGN. Background technique [0002] In the traditional public switched telephone network (PSTN), many types of circuit switches can provide ISDN attendant console functions. Generally, the ISDN attendant console can be a computer with an ISDN card inserted, and attendant console processing software runs on the computer. The ISDN card provides an ISDN 2B+D interface and is connected to a switch that supports the ISDN 2B+D interface through a subscriber line. As the switchboard of group users such as enterprises, the ISDN attendant console provides call transfer services for group users, manages data such as the call-out authority of phone users in the group, and receives call lists for calls made by phone users in the group to make call...
