GPRS (general packet radio service) module with FTP (file transfer protocol) function and FTP method implemented by GPRS module

Abstract

The invention discloses a GPRS (general package radio service) module with an FTP (file transfer protocol) function and an FTP method implemented by the GPRS module. The GPRS module comprises an intelligent terminal communication unit, an AT (attention) command response unit and an FTP communication unit; the intelligent terminal communication unit is used for being communicated and connected with an intelligent terminal; the AT command response unit is used for receiving AT commands issued by the intelligent terminal and interpreting the received AT commands to obtain FTP control instructions; the FTP communication unit can be connected with an FTP file server and can execute file operation according to the FTP control instructions. The GPRS module and the FTP method have the advantages that the intelligent terminal can control the GPRS module via corresponding interfaces, and the GPRS module can be connected with the FTP file server, so that the FTP function can be realized.

Description

Technical field [0001] The present invention belongs to the field of communication technology, and specifically relates to a GPRS module with FTP transmission function and a method for implementing FTP (File Transfer Protocol) transmission. Background technique [0002] With the development of wireless communication technology and the widespread application of GSM / GPRS, the application of wireless packet service GPRS communication in smart terminals has become more and more extensive. In GPRS communication applications, smart terminals need to use the TCP / IP protocol stack, and need to use the FTP function to complete file transfer functions such as data, parameters, and upgrades. figure 1 Shown. [0003] However, as figure 2 As shown, the existing GPRS module can usually only realize the underlying data transmission, and the FTP function is realized by the intelligent terminal, and the realization is more complicated, and the software and hardware requirements of the intelligent ...

AI Technical Summary

Problems solved by technology

[0003] However, if figure 2 As shown, the existing GPRS module can usually only realize the data transmission of the bottom layer, and the FTP function is realized by the smart terminal, and the realization is relatively complicated, and the software and hardware requirements of the smart terminal are relatively high, so the product cost of the smart terminal is relatively high. And it brings great development difficulty to developers, and it is difficult to popularize and apply in intelligent terminals mainly based on single-chip microcomputer systems
