Voice, Modem and Fax full control method

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 the initiator 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 method for full control of voice, Modem and Fax. Background technique [0002] The traditional TDM network implements modem and fax services through capacity negotiation between terminal devices after establishing a voice bearer channel between the calling party and the called party. The network equipment does not participate in the process of terminal equipment capability negotiation, and the signaling is transparently transmitted through the bearer channel to realize the capability negotiation process between the calling device and the called device. [0003] NGN network gateway equipment has become a relatively mature technology for modem and fax signal detection, which provides a foundation for the NGN network's modem and fax full control technology. NGN is based on softswitch as its core and can provide integrated multimedia services such as voice, video, and...

AI Technical Summary

Problems solved by technology

Since there is no signaling negotiation mechanism defined between control devices, if two intercommunicating control devices use different negotiation mechanisms, these services will not be realized
