Faxing method, gateway and system

Abstract

The invention discloses a fax method. The method includes that firstly, a fax gateway receives a first fax call sent from an original fax terminal to a target fax terminal, stop the first fax call when the original fax terminal is not the sender of non-fax page data and memorize the number of the original fax terminal and the number of the target fax terminal; secondly, start a second fax call tothe target fax terminal, receive and memorize the fax page data transmitted by the target fax terminal through the second fax call; thirdly, start a third fax call to the original fax terminal and transmit the fax page data to the original fax terminal through the third fax call. Through the fax gateway introduced to the fax system and supporting the T.30 / T.38 protocol, the embodiment of the invention resolves the first real-time faxing into times of real-time faxing, reducing the delay of transmission in real-time faxing and improve the faxing success ratio.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a facsimile method, a facsimile gateway and a facsimile system. Background technique [0002] Existing fax is divided into real-time fax and non-real-time fax, wherein, real-time fax has three classes, including: PSTN (Public Switched Telephone Network, Public Switched Telephone Network) fax, wireless fax and IP fax, real-time fax requires strong real-time performance, but In wireless real-time faxes and real-time faxes with large delays over IP bearers, there are air interface delays, bit errors and resulting retransmissions, as well as excessive modulation and demodulation processes. For example, a standard MS (Mobile Subscriber, Mobile The wireless fax from the user) to the MS has to go through 3 groups of 6 modulation and demodulation processes, which directly lead to excessive system delay, and the resulting low fax success rate; in addition, in some special applicatio...

Problems solved by technology

[0005] This kind of fax actually realizes the fax of PSTN-Internet. The fax users on one side need to use the Email client or the fax machine supporting T. The number of .30 fax machines is as high as hundreds of millions, and it is impossible to replace them all with T.37 fax machines

In addition, the use of Email does not conform to people's understanding of fax

The reason why fax is widely used is that people think that the content it transmits is direct, authentic and reliable, so it has formal meaning in many occasions; and the way of email makes fax not real-time, so it has a certain security. Many problems, poor credibility
