Embodiment Construction

[0043] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0044] Referring to Figure 1, the softswitch equipment includes a first softswitch (Softswitch1) and a second softswitch (softswitch2). The first softswitch (Softswitch1) and the second softswitch (softswitch2) are the core control equipment of the NGN network. in IP network. The communication between the two softswitches is realized through IP protocol, such as SIP protocol.

[0045] The gateway device includes a first media gateway and a second media gateway. The first media gateway and the second media gateway are gateway access devices, which are used to access terminal devices and are controlled by the softswitch device. The communication between the gateway device and the softswitch device is realized through IP protocol, such as H.248, SIP and so on.

[0046] Modem terminal 1 and Modem terminal 2 are TDM circuit interface facsimile...

Abstract

The disclosed full control method for all of speech, Modem and Fax comprises: the calling user builds speech carrying channel; the first media gateway notifies the first soft exchange for the detected Fax or Modem affair; the latter indicates the first media gateway to switch into fax or modem state; the first soft exchange initiates the negotiation and building request for the fax media flow to the second soft exchange; the latter receives message and indicates the second media gateway to switch into fax or modem state; then the second soft exchange matches the fax or modem capacity with theinitiator through signaling message; finally, the calling builds fax or modem channel with the called.

Description

technical field [0001] The present invention relates to a Next Generation Network (NGN) technology, in particular, to a full control method for voice, Modem and Fax. Background technique [0002] The traditional TDM network implements Modem and Fax services through capability negotiation between terminal devices after establishing a voice bearer channel between the calling party and the called party. The network device does not participate in the capability negotiation process of the terminal device, and the signaling is transparently transmitted through the bearer channel to realize the capability negotiation process between the calling and called devices. [0003] The gateway device of NGN network has become a relatively mature technology for Modem and Fax signal detection, which provides the foundation for the Modem and Fax full control technology of NGN network. NGN takes softswitch as the core and can provide integrated multimedia services such as voice, video, and dat...
