Problems solved by technology

[0004] At present, in the technology of resuming transmission at the mobile terminal, when a file is artificially divided, the file is generally divided into 8-10 file blocks, and then the size of each file block is determined according to the size of the entire file. The entire file is relatively small, and each file obtained after division is relatively small, so when uploading or downloading multiple smaller files, the speed will be faster and the system performance will be relatively high; If each file is relatively large, when uploading or downloading multiple large files, the speed will be relatively slow, the system performance will be relatively low, and file transfers often freeze on the mobile phone.

Embodiment 1

[0055] Such as figure 2 and 3As shown, the embodiment of the present invention provides a method for resumed downloading of files downloaded from a mobile terminal. The implementation process of this method is:

[0056] The mobile terminal connects to the server to obtain the size of the downloaded file, and checks the number of the basic unit of the file on the local server to determine whether the file is in an unfinished state. If it is in an unfinished state, divide the file from the basic unit with the smallest number in the unfinished state recorded in the local database, and perform multi-threaded download of the divided basic unit; if there is no unfinished file , the entire file is first divided, and then multi-threaded download is started.

[0057] Among them, the following method can be used for file division: the entire file is divided into a "basic unit" with a size of 2M. Six parts of basic information including local cache address and download status.

Embodiment 2

[0063] Such as Figure 4 and 5 As shown, the embodiment of the present invention provides a method for resuming uploading of files uploaded by the mobile phone. The implementation process of this method is:

[0064] The mobile terminal selects the file to be uploaded locally, sends a request to the server, queries the local database, and judges whether there is an uploaded file record in the unfinished state. If so, obtains the basic unit with the smallest number in the unfinished state. Starting from the basic unit with the smallest number, upload the unfinished file. If there is no record, first divide the entire file into multiple basic units, and then start multi-threading to start uploading.

[0065] Among them, the following method can be used for file division: the file size is 2M as a "basic unit", and the "basic unit" includes

[0066] "File block" also includes the basic information of six parts: file block number, full file name, server address where the file is ...

Abstract

The invention discloses a method for file breakpoint resuming of a mobile phone side, and relates to the technical field of file transmission of a mobile phone side. According to the method, a file to be transmitted is divided into a plurality of basic units, when an interruption occurs in a process of transmitting the file, the basic unit with the smallest serial number in an uncompleted state can serve as a starting point, and the basic units in uncompleted states are transmitted till transmission is completed. Through use of the basic units and setting of the serial numbers, names, server address, local caching address, local caching address, download states and file block size of the basic units, security and efficiency of transmission can be improved.

Description

technical field [0001] The invention relates to the technical field of mobile phone file transmission, in particular to a method for resumed transmission of files at the mobile phone. Background technique [0002] In the process of downloading or uploading files on the mobile phone, when the mobile phone has a network failure, is interrupted by an incoming call, or the battery of the mobile phone is insufficient, in order to increase the speed of the next download or upload, you can generally use the function of resuming uploads Continue downloading or uploading files from the breakpoint. [0003] Among them, the principle of resumable uploading on the mobile phone is: when downloading or uploading, the downloading or uploading task (a file or a compressed package) is artificially divided into several parts, and each part uses a thread for uploading or downloading, if When the download or upload is disconnected due to network failure, etc., next time you can continue to upl...
