A raw new file, upload or download (or simultaneously), produce or eliminate a FileVersion, and local file is synchronously shared
Deng.
Produce a new file, can be that the nearest version to file produces a wave file, or to file
Other early versions produce a copy, and file difference information.Upload and refer to upload a complete version, or file is poor
Different part road other equipment, or arrive centralized storage, or simultaneously.Download and refer to download a complete version, or file
Difference section is to other equipment to locally stored.
Configuration or cancellation configuration refer to the safe handling for file storage access.For example, when equipment be in dangerous
In the network environment of (e.g., public network), the file content with secret property will be automatically protected, and becomes not can contact.
Correspond to therewith, when equipment comes back in safe network environment, originally start the file content of security mechanism protection, can be automatically
Cancel protection, such that it is able to from the contact of new class.
Summary refers to upload, and (or) downloads the summary of a FileVersion.For example, the several leading row of mail, the regarding of several frames
Frequently, or a few minutes audio file etc..
When file synchronization is shared, system will determine it is only maintenance documentation different information, or safeguards complete
Duplicate of the document.This decision-making is system according to learning, or the panoramic information that obtains and make.For example, it may be file
Use pattern on the target device (before file download, service condition) possible on the target device to know this file.
Another one example is that when systematic learning knows that the probability that file is lost becomes big, and file on the target device is lonely
This, is thus duplicate of the document is uploaded to other equipment as early as possible, or centralized storage.If when system understands, equipment is in public
Among network, when cannot meet for the sensitive file security protection of secret, this file returns by system auto-destruct.
System should execute for when version management operation be also required to make decisions.For example, for cost of implementation
Optimize, when needing to download specific file, return and complete required associative operation before target device leaves wifi.Meanwhile, system
It is also required to understand the bandwidth traffic information controlling network, the relevant information such as amount of batteries of equipment completely, could precisely make in time
Go out corresponding version management operation.

Fileinfo, thus effectively set up the metadata of time file.Identical, bench device or the network equipment can also run version
This control module.Above-mentioned three kinds of version control module are all to be all the abstract example that general version controls.But, each of which
Concrete behavior pattern can be entirely different according to oneself residing environment and background.
System structure module: file metadata.File metadata module record preserves the attribute information with regard to file, example
As, the size of file, proprietary rightss, file originates from, file type (e.g., text, audio frequency, video etc.), the content of modification, modification
Frequency, file redundancy (e.g., how many duplicates of the document are saved), version information, which kind of that user has on that equipment
FileVersion, etc..
System structure module: module input.No matter being in mobile terminal, or terminal console, version control module defeated
Enter information and may include that meta data file, environmental background information, the use pattern of user, the daily agenda of user, user's is inclined

Dump energy, networking provides a loan, and gps information.Version control module uses above-mentioned input information, can obtain according to algorithm
Excellent FileVersion controls, and synchronous shared operation.For example, the consumption of the minimizing battery of maximum possible, obtains maximum simultaneously
File workability.Existing security protocol and policy can also be based on, in the environment also in secure network, in advance will
FileVersion get local storage.
Edition control method and flow process.As Fig. 2, describe version control module based on known various environment and terminal
Attribute, and it is made whether to replicate complete file, or the decision of file summary.In the preparatory stage, whether systems inspection file has
The part updating, and whether be latest edition.Whether the subsequent effect of system synchronous documents if necessary, now in secure network ring
Border.If it does, condition c > whether (d x b) meet.Wherein c=(file size/bandwidth) * (every bit transfer
Battery consumption), d=(preset parameter, such as d=10%), b=present battery amount.Then, set in advance by user in inspection
Whether network bandwidth threshold values meets transmission conditions.
Application example, such as Fig. 3, mobile terminal device is in the network environment of a safety, logical by safety with high in the clouds
Letter passage is connected, and battery is in full load condition, and has the preferable network bandwidth.Based on above-mentioned information, Version Control can
To determine following operation: 1) if the most of users participating in meeting have obtained file, prefetch file to locally stored
Area, 2) share according to the agenda arrangement file synchronization of user and (before leaving present ecotopia, complete the same of file
Step is shared), 3) after the completion of file modification, upload complete redaction, and the different information with previous version.
The above be only the preferred embodiment of the present invention it should be pointed out that: for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
