Description
Technical field
The present invention relates to mobile communication technology field, more specifically, is related to a kind of document down loading method, device and is
System.
Background technology
With the popularization and development of network, people not only through network enjoy it is increasing service, and information is obtained
Take also become it is highly efficient.Data form on network is various, except the data based on WEB forms, other data types
Could use after generally requiring to download, such as e-book, MP3, application/game installation kit etc., therefore, download is that user is main
One of internet behavior.
Daily computer equipment is compared, while handheld device has portability, there is also that network signal is unstable to ask
Topic, such as, when user moves to the weaker region of interior or other radio signal propagations, the network information will die down and cause net
Network connection failure.If the user while handheld terminal runs into such situation when downloading big file, downloading task termination is may result in.
Number of site can provide breakpoint transmission function, and user can continue to download according to download progress before.If website does not carry
For breakpoint transmission function, then be again started up downloading task, then need to re-download, when network is bad, user is multiple
Repeated downloads, waste many flows but cannot all download to complete file.
For some consider the website of flow operation cost, our station file download can be limited, such as only be allowed
Single IP single threads are downloaded, and download peak value is 50K/S, downloads the resource of these websites, it may be desirable to the more time, have a strong impact on
User's downloading experience on mobile terminals：Reducing sharply and bringing terminal to generate heat for stand-by time can be caused long lasting for downloading
Problem.
It is related that existing " offline to download " mainly solves the problems, such as that power consumption is downloaded in on-hook：By downloaded software（Registration）With
The offline downloading task of family manual creation, after the completion of offline download, downloads the file for obtaining and can be retained in the offline download space of user.
At this moment, the offline download space of User logs in, is downloading file again from offline download space.
Therefore, existing method for down loading, there is a problem of restarting download waste flow and download stability is poor.
The content of the invention
In view of the above problems, it is an object of the present invention to provide it is a kind of by mobile terminal perform document down loading method device and be
System, helps the faster more stable download file of user and reduces flow waste.
According to an aspect of the present invention, there is provided a kind of document down loading method, including：
Creating and corresponding offline downloading task is created after performing the first downloading task and be sent to offline download service
Device, first downloading task are used to indicate that mobile terminal downloads file from destination server；
When file download completion message and unfinished the first downloading task that offline download server is returned is received, wound
Build for the second downloading task from the offline download server acquisition file to be downloaded；And
Based on the first downloading task and the second downloading task that are created, according to the mode that multi-source is downloaded, while from target
Server and offline download server do not complete the content downloaded in continuing to obtain file to be downloaded.
Wherein, in the case of restarting after the first downloading task is aborted, methods described also includes：
When the destination server supports breakpoint transmission, downloaded based on the first downloading task for being created and second and appointed
Business, according to the mode that multi-source is downloaded, while continuing to obtain in file to be downloaded not from destination server and offline download server
The content downloaded is completed, or
When the destination server does not support breakpoint transmission, based on the second downloading task for being created, from offline download
Server does not complete the content downloaded in continuing to obtain file to be downloaded.
On the other hand, the present invention also provides a kind of file downloading device, including：
First downloading task creating unit, for creating the first downloading task, first downloading task is used to indicate to move
Dynamic terminal downloads file from destination server；
File download unit, comes from destination server downloading object file for performing the first downloading task；
Offline downloading task creating unit, for after creating and performing the first downloading task, create it is corresponding it is offline under
Load task is simultaneously sent to offline download server,；
Second downloading task creating unit, for receiving the file download completion message that offline download server is returned
And first downloading task when not completing, create for the second download of the file to be downloaded is obtained from offline download server
Task,
The file download unit is additionally configured to after the second downloading task is created, and is appointed based on the first download for being created
Business and the second downloading task, according to the mode that multi-source is downloaded, while continuing to obtain from destination server and offline download server
The content downloaded is not completed in file to be downloaded.
Wherein, in the case of restarting after the first downloading task is aborted,
The file download unit is configured to when the destination server supports breakpoint transmission, based on for being created
One downloading task and the second downloading task, according to the mode that multi-source is downloaded, while from destination server and offline download server
The content downloaded is not completed in continuing to obtain file to be downloaded, or
The file download unit is configured to when the destination server does not support breakpoint transmission, based on what is created
Second downloading task, continues to obtain from offline download server the content that download is not completed in file to be downloaded.
Wherein, described device also includes：
File download completion message creating unit, for, after mobile terminal completes to download the file to be downloaded, creating
File download completion message is built, the file download completion message is used to indicate that the offline download server deletion is described offline
File after downloading task and the download；And
File download completion message transmitting element, completes for sending the file download to the offline download server
Message.
On the other hand, the present invention also provides a kind of file download system, including：
File downloading device, for creating and creating corresponding offline downloading task after performing the first downloading task concurrent
Offline download server is sent to, first downloading task is used to indicate that mobile terminal downloads file from destination server, is connecing
Receive file download completion message that offline download server returns and when the first downloading task is not completed, create for from offline
Download server obtains the second downloading task of the file to be downloaded, and, based on the first downloading task for being created and
Second downloading task, according to the mode that multi-source is downloaded, while continue acquisition from destination server and offline download server treating down
The content downloaded is not completed in published article part；
Destination server, downloads content for providing to the file downloading device according to first downloading task；
Offline download server, for according to the offline downloading task and second downloading task under the file
Carry and offer download content is provided.
From above-mentioned technical proposal as can be seen that the present invention is also created when creating and downloading the task of file from destination server
Offline downloading task, thus can file download from destination server do not complete and download offline complete when, while from
Destination server and offline download server do not complete the content downloaded in continuing to obtain file to be downloaded, so as to avoid flow wave
Take and sustainedly and stably can download file, improve user's downloading experience.
