File transmission method, device and mobile terminal

Abstract

The invention discloses a file transmission method, a file transmission device, and a mobile terminal. The method includes the following steps that: whether the size of a file exceeds a preset file size is judged before the upload of the file is started; if the size of the file exceeds the preset file size, the file is dynamically divided according to a network state, so that the file is uploadedin the form of file blocks; and if the size of the file does not exceed the preset file size, the file is uploaded directly. According to the file transmission method, the file transmission device, and the mobile terminal of the invention, whether the block transmission of the file is to be performed is judged according to the size of the file before the file is transmitted; when the block transmission of the file is required, a proper file block size is calculated dynamically according to the network state, and therefore, the file can be transmitted more effectively, and data retransmissionduring recovery can be decreased; the calculation and adjustment of the file blocks are not required when a network is stable; and the file blocks are dynamically re-calculated according to the real-time network state when the network state fluctuates, and therefore, the file block size is dynamically calculated and adjusted so as to adapt to the network condition, efficient network transmissioncan be achieved, and the amount of data during retransmission after interruption can be reduced.

Description

technical field [0001] The present invention relates to the field of file transmission, in particular to a file transmission method, device and mobile terminal. Background technique [0002] With the rapid development of the Internet and the comprehensive popularization of mobile terminals, more and more people use mobile devices for daily work and communication anytime, anywhere. How to perform efficient, stable and recoverable data transmission on the mobile terminal has become the focus of research on mobile terminal data transmission solutions. [0003] Generally, the existing file upload solution is to directly upload the entire file without dividing the file into blocks. In this solution, when the transmission is interrupted due to network or other reasons, the entire file needs to be uploaded again, which wastes network traffic and transmission time, and is not good for user experience. [0004] A further solution is to divide the entire file into fixed-size blocks ...

AI Technical Summary

Problems solved by technology

If the network condition is good and the file blocks are small, it will take more time to divide the small data file blocks one by one in a continuous loop; if the network condition is not good and the file blocks are relatively large, the retransmission will be interrupted It is necessary to repeatedly upload the blocks that failed to be uploaded at the moment, which greatly reduces or even loses the advantage of file block transfer
