Abstract

The invention relates to a file transmission method, file transmission equipment and a computer readable storage medium. The file transmission method is operated on file transmission equipment, and comprises the following steps: in response to a control instruction sent by terminal equipment, establishing control link connection with an FTP server; responding to a download file designation instruction sent by the terminal equipment, and establishing data link connection with the FTP server; sending a file downloading instruction to the FTP server to control the data link connection to start afile downloading operation; and in the file downloading process, controlling to send a control link connection keep-alive instruction to the FTP server at a preset time interval. Thus, in the file transmission process, the link connection keep-alive instruction is sent at the preset time interval until file downloading is completed, and the control link can be prevented from being removed by the server due to the fact that idle time is too long in the file downloading process.

Description

technical field [0001] The invention relates to the technical field of computer data transmission, in particular to a file transmission method, a file transmission device and a computer-readable storage medium. Background technique [0002] With the development of wireless communication technology, the use of mobile Internet terminals with network connection capabilities is becoming more and more popular. After the mobile Internet terminal is plugged with a SIM (Subscriber Identification Module, identification card), it can use a network protocol provided by the application layer, such as a file transfer protocol (File Transfer Protocol, FTP), to realize uploading and downloading of remote files. [0003] The FTP protocol model is designed based on the client-server (Client-Server, C / S) model, and at least consists of a mobile Internet terminal, an FTP communication device and an FTP server. Wherein, the mobile Internet terminal device and the FTP communication device perfo...
