Problems solved by technology

[0004] No matter which transmission method is used to transfer files, there are disadvantages: using Bluetooth to transfer files, the sending user's client and the receiving user's client require multiple steps of operation, such as needing to open its own Bluetooth module, pairing and connecting And transfer files, the use threshold is high, the user experience is not good, and it is complicated and difficult to realize; the instant messaging method is used to transfer files, and the point-to-point method is adopted, so it is impossible to transfer files to multiple receiving users at the same time; the microblogging method is adopted When transferring files, the file format is limited to image format, and files of other file formats cannot be transferred
[0005] In summary, there is currently no method for transferring files that can simply and easily transfer files of various file formats to multiple receiving user clients at the same time

Embodiment Construction

[0058] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0059] In order to simply and easily transmit files of various file formats to multiple receiving user clients at the same time, the client of the present invention uses the MD5 algorithm to calculate the digest value of the file to be transmitted, and then sends the file and the digest value to the server Store, convert the summary value into a DTMF signal according to the corresponding relationship between the dual-tone multi-frequency (DTMF) signal and the summary value, and then send it to the receiving user's client; Correspondence of numbers After obtaining the digest value, send an acquisition request carrying the digest value to the server, and receive the file corresponding to the digest value returned by the server.

[0060] In this way, the f...

Abstract

The invention discloses a file transmission method, system and device. After the file to be transmitted by the sending user client of the invention calculates the digest value using the MD5 algorithm, the file and the digest value are sent to the server for storage. According to the DTMF signal and the digest value The corresponding relationship converts the digest value into a DTMF signal and sends it to the receiving user's client; after receiving the DTMF signal, the receiving user's client gets the digest value according to the corresponding relationship between the DTMF signal and the number, and sends the digest to the server Value acquisition request, receiving the file corresponding to the summary value returned by the server. Therefore, the present invention can simply and easily realize the simultaneous transmission of files in the medium file format to the clients of multiple receiving users.

Description

technical field [0001] The present invention relates to the communication field, in particular to a file transmission method, system and device. Background technique [0002] With the development of communication technology, more and more services can be realized, and the file transfer service is one of them. When multiple users conduct business talks, parties, or dinners, etc., it is often necessary to share phone numbers among the multiple users. image or audio files, in this case, it is necessary to transfer files between multiple users. [0003] At present, Bluetooth, instant messaging or microblog are often used for file transfer among multiple users. When using bluetooth to transfer files, the client of the sending user and the client of the receiving user open their own bluetooth modules respectively. After the pairing and connection are successful, the client of the sending user transmits the file to the client of the receiving user through the bluetooth channel. ...
