Description

technical field

[0001] The present invention relates to network communication technology, and more specifically relates to a wireless facsimile system. Background technique

[0002] With the development of information and intelligence, the existing fixed office methods can no longer meet the needs of the rapid development of social informatization. More and more business people need mobile business office, which brings new business growth points to wireless communication. Two of the three major components of wireless office: clear voice calls and high-speed wireless data transmission have been fully realized, but the wireless fax service, which is an important part of wireless office, has not been realized.

[0003] Currently, the wireless facsimile network available in the 2G mobile communication network is implemented by superimposing the T.30 protocol on the basis of the CSD (Circuit Switch Data) technology in the CS (Circuit Switch) domain. Since CSD technology is a vir...
