摘要:
The invention discloses a method of implementing a fax in a next generation network, comprising steps of: either of two media gateways notifying a media gateway controller upon detection of a Fax Start signal when they communicate with each other; the media gateway controller sending in parallel a Modify command to the media gateways at the two ends of the communication based upon a negotiated fax codec mode, so as to modify the codec mode; the media gateways at the two ends modifying the codec mode based upon the Modify command, returning a Reply message to the media gateway controller, and starting a fax. The invention can reduce time for a fax switching and improve success ratio of a fax negotiation.

A method for limiting bit rate in IP facsimile, in this method the highest bit rate that the called gateway allows is determined, after the call connection is set up, the called fax machine transmits the digital identification containing the highest facsimile bit rate that the called fax machine provides, the called gateway compares the highest facsimile bit rate that the called fax machine provides with the determined highest bit rate that the called gateway allows, then selects the lower and inserts in the frame and transmits to the calling fax machine, the calling fax machine compares the bit rate with the highest bit rate that the calling fax machine itself provides, the lowest will be the highest bit rate at which message is transmitted, then the message is transmitted, confirmed, then the call connection is released. In this method, when the network becomes bad, the highest facsimile bit rate is limited through gateway to improve quality of pictures. A method for achieving limiting bit rate in IP facsimile by a gateway is also proposed in the present invention.

The dash-dash broken lines in the drawings depict portions of the microscope stand and form no part of the claimed design. The dot-dash broken lines demarcate the boundaries of the enlarged views and form no part of the claimed design.

A method for limiting bit rate in IP facsimile, in this method the highest bit rate that the called gateway allows is determined, after the call connection is set up, the called fax machine transmits the digital identification containing the highest facsimile bit rate that the called fax machine provides, the called gateway compares the highest facsimile bit rate that the called fax machine provides with the determined highest bit rate that the called gateway allows, then selects the lower and inserts in the frame and transmits to the calling fax machine, the calling fax machine compares the bit rate with the highest bit rate that the calling fax machine itself provides, the lowest will be the highest bit rate at which message is transmitted, then the message is transmitted, confirmed, then the call connection is released. In this method, when the network becomes bad, the highest facsimile bit rate is limited through gateway to improve quality of pictures. A method for achieving limiting bit rate in IP facsimile by a gateway is also proposed in the present invention.
