Problems solved by technology

If the website does not provide the function of resuming downloading from breakpoints, then restarting the download task requires re-downloading. When the network is not good, the user downloads repeatedly many times, which wastes a lot of traffic but cannot download the complete file.
[0004] For some websites that consider traffic operating costs, file downloads on this site will be restricted. For example, only single-IP single-thread downloads are allowed, and the download peak value is 50K / S. Downloading the resources of these websites will take more time and seriously affect Improve the user's download experience on mobile terminals: continuous downloading for a long time will lead to a sharp reduction in standby time and bring about terminal heating problems
[0005] The existing "offline download" is mainly to solve the problem related to the power consumption of on-hook download: the (registered) user who downloads the software manually creates an offline download task, and after the offline download is completed, the downloaded file will be kept in the user's offline download space
[0006] Therefore, the existing download method has the problems of wasting traffic and poor download stability by restarting the download

Embodiment Construction

[0039] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0040] Aiming at the problems of wasting traffic and poor download stability when restarting download in the prior art, the present invention provides a file download method. The method automatically creates a corresponding silent offline download task on the offline download server after the first download task starts, and creates a second download task after the silent offline download task is completed, which will be saved in the offline download server for public temporary download. The downloaded file is used as the second download source, and according to the multi-source download method, the content of the unfinished download in the file to be downloaded is continuously obtained from the target server and the offline download server at the same time, thereby avoiding traffic waste and sustainable downloading. Download files stably and i...

Abstract

The invention provides a file downloading method, device and system. The method comprises the steps: after creating and executing a first downloading task, creating a corresponding offline downloading task and sending the offline downloading task to an offline downloading server, wherein the first downloading task is used for indicating a mobile terminal to download a file from a target server; after receiving a file downloading completion message returned by the offline downloading server and not finishing the first downloading task, creating a second downloading task for obtaining a file to be downloaded from the offline downloading server; based on the created first and second downloading tasks, according to a multi-source downloading mode, continuously obtaining contents, which are not downloaded, of the file to be downloaded from the target server and the offline downloading server simultaneously. With the adoption of the file downloading method, device and system, a user can obtain more excellent downloading experience.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and more specifically, to a file downloading method, device and system. Background technique [0002] With the popularization and development of the Internet, people not only enjoy more and more services through the Internet, but also obtain information more efficiently. There are many data formats on the Internet. Except for data based on WEB format, other data types often need to be downloaded before use, such as e-books, MP3, application / game installation packages, etc. Therefore, downloading is one of the most important online behaviors of users. one. [0003] Compared with everyday computer equipment, handheld devices are portable, but there are also problems with unstable network signals. For example, when users move indoors or other areas where wireless signal propagation is weak, network information will become weak and cause network connection problems. fail. If t...
