Method for reducing wireless facsimile delay

Abstract

First, the method determines whether the current call is a call between mobile fax user and mobile fax user; if yes, then when establishing call between calling IWF and called IWF, the method does not need to start up MODEM, instead two IWF are connected through digital signal directly; otherwise, negotiation communication is carried through MODEM between calling IWF and called IWF according to current protocol. Advantages are: data transmission between calling IWF and called IWF without MODEM is simpler, reduced probability of inducting error code, and time delay between calling IWF and called IWF so as to raise success ratio of fax.

Description

technical field [0001] The invention relates to facsimile technology, in particular to a method for reducing wireless facsimile delay. Background technique [0002] Facsimile communication is a communication method that uses scanning and photoelectric conversion technology to send static images such as text, pictures, and photos from the source to the receiving end through wired or wireless channels, and reproduce the still images at the receiving end. Since the 1970s, due to the opening of the file fax service on the public telephone exchange network, fax communication has been vigorously developed and has become one of the means for people to transmit information. [0003] figure 1 It is a schematic diagram of a fax network. The fax machine (FAX) on the public switched telephone network (PSTN) side is directly connected to the PSTN network, and the fax machine on the mobile side is connected to the wireless network through a fixed wireless terminal (FWT). In order to be ...
