Method and system for prohibiting error correction mode during IP faxing

Abstract

The invention discloses a method and a system for prohibiting an error correction mode during the IP faxing and aims to solve the problem that the real-time performance of the prior IP faxing is not strong. The method comprises the following steps: after the reported information about the error correction mode capacity of a receiver facsimile machine is received, at least one of a receiver facsimile machine gateway and a sender facsimile machine gateway judges whether the sender facsimile machine support the correction mode capacity according to the reported information about the error correction mode capacity, modifies the reported information about the error correction mode capacity to a non-support correction mode message in real time, and then forwards the non-support correction mode message. The system comprises an error correction mode capacity reporting unit used for reporting the information about the error correction mode capacity of the receiver facsimile, an error correction mode capacity judging unit used for judging whether the receiver facsimile support the error correction mode capacity, an error correction mode capacity modifying unit used for modifying the reported information about the correction mode capacity into the non-support correction mode information, and a forwarding unit used for forwarding the information about the correction mode capacity. The invention reduces the time delay in the facsimile posting and enhances the real-time performance.

Description

technical field [0001] The invention relates to a method and a system for prohibiting an error correction mode in Internet Protocol (IP, Internet Protocol) fax. Background technique [0002] With the development of the Internet, the T.38 protocol for real-time fax relay on the IP network has also been more and more used. Generally, the T.38 gateway at one end demodulates the modulated signal sent by the fax machine connected to it, encapsulates the demodulated data into a message specified in the T.38 protocol, and sends it to the T.38 gateway at the opposite end through the IP network. gateway. The opposite end T.38 gateway parses out the data from the received message, and modulates it to the fax machine of the opposite end T.38 gateway. The following briefly introduces the process of IP fax. [0003] The first is the call establishment stage, which is completed manually or automatically, which is consistent with the call process of IP phones. After the call is establi...

Problems solved by technology

[0005] The IP fax in the error correction mode can guarantee the quality of the transmitted data, but because it adopts the error correction mode, the transmission speed will be greatly reduced, and the real-time performance will also be reduced. For the IP network, its biggest feature is that Data transmission is relatively reliable but poor in real-time performance. Therefore, most users are not used to IP fax in error correction mode, but are more accustomed to the real-time method similar to ordinary fax
