Abstract

The present invention discloses a device and method for improving the success rate of fax in the environment of large satellite time delay and packet loss. The fax message is determined as the first message; according to the ACK data corresponding to the first message sent by the destination terminal, calculate the average packet loss rate and average delay of the fax message; based on the average packet loss rate and the average Delay, to control the retransmission batch of the second message not received by the destination terminal in the fax message, so as to resend the second message to the destination terminal within the effective remaining time, and realize the unsuccessful sending of the fax message The retransmission is based on the average packet loss rate and average delay to control the retransmission batch, which reduces the packet loss probability of fax messages during retransmission and improves the fax success rate.

Description

technical field [0001] The present invention relates to the technical field of facsimile, in particular to a facsimile message transmission method, device, equipment and computer-readable storage medium. Background technique [0002] There are two typical transmission modes for fax in the traditional switched telephone network, namely T.30 and T.38 modes. T.38 mode is a protocol mode that converts fax messages under T.30 mode into IP. T.30 mode is applied in the fax environment with high packet loss rate and long delay, and the fax failure rate will be greatly increased. The main reason is that the fax packet loss in the fax C stage is serious, which causes the fax device at the receiving end to print and detect the fax message. Automatic disconnection due to abnormality, ending the fax process, even if the T.38 mode has a redundant error correction function, it is not enough to solve the problem of low fax success rate in the fax environment with high packet loss rate and l...
