Faxing control method and device

Abstract

The invention discloses a faxing control method and a faxing control device. The faxing control method comprises the following steps of: transmitting a called terminal identification (CED) signal to a fax machine; acquiring a first time interval at which the fax machine retransmits a digital command signal (DCS); and controlling and regulating a second time interval between the forwarding of a digital identification signal (DIS) of an opposite-end fax machine and the reception of the DIS of the fax machine according to the first time interval, so that the fax machine receives the DCS to perform a faxing service. In the faxing control method and the faxing control device provided by the invention, a fixed wireless terminal acquires the time interval at which the fax machine retransmits the DIS, and regulates own time of forwarding the DCS returned by the opposite-end fax machine, so that data collisions caused by sameness between the time at which the fixed wireless terminal forwards the DCS returned by the opposite-end fax machine and the time at which the fixed wireless terminal receives the DIS retransmitted by the fax machine are avoided, and the success rate of the faxing service is increased.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a facsimile control method and device. Background technique [0002] The FAX (fax) service has been realized in PSTN (Public Switched Telephone Network, Public Switched Telephone Network), but due to the difference between the wireless network and PSTN, there are many problems in the FAX service in the wireless network. [0003] For example, in a wireless network, the FAX machine will send a DIS (Digital Command Signal, digital command signal) to the FWT after receiving the CED (Called Terminal Identification) signal sent by the FWT (Fixed wireless terminal, fixed wireless terminal), The FWT forwards the DIS to the peer FAX machine, the peer FAX machine replies with a DCS (Digital Identification Signal, digital identification signal) to the FWT, and the FWT forwards the replied DCS to the FAX machine. [0004] If the FAX machine does not receive the reply DCS within a cer...

AI Technical Summary

Problems solved by technology

[0004] If the FAX machine does not receive the reply DCS within a certain period of time after sending the DIS, the FAX machine will re-send the DIS. Due to the large delay in the wireless network, the time when the FWT forwards the peer FAX machine to reply to the DCS is just the same as the FWT received. The time until the FAX machine retransmits the DIS is the same, resulting in data collision. When the retransmission times out, the fax service fails.
