The defect of solution equipment existence or the function of increase equipment, need equipment publisher to systems soft ware or application
Program is upgraded.The mode of upgrading mainly has TF card upgrade and OTA upgrading.
OTA English full name is Over-the-Air Technology, i.e. the meaning of space download technology.OTA
Upgrading have two types, both types respectively: difference (or increment) OTA and whole bag OTA.
In OTA two kinds upgrading type, it is generally the case that the size of whole bag is comparatively close to whole firmware
Mirror image.And the most specific restriction of difference bag, can be the biggest with whole bag, it is also possible to the most several
KB, but under normal circumstances, difference bag is more much smaller than whole bag.
The difference AKU of OTA is the least, general several M to tens M, if with network upgrade,
Very convenient, be substantially click in system several under just complete upgrading, and the most important thing is, OTA
Upgrading is without Backup Data, and short a few minutes just settle all upgrade jobs, and all data all can intact nothing
That damages remains.
Although the mode of difference upgrading has advantage, but utilizes difference instrument to create difference in prior art
Bag to carry out difference for each platform, each chip, and inefficiency, amount of storage are big.
For above-mentioned technical problem, prior art there is no good solution.

Detailed description of the invention
Below in conjunction with accompanying drawing, the detailed description of the invention of the present invention is described in detail.It should be appreciated that
Detailed description of the invention described herein is merely to illustrate and explains the present invention, is not limited to this
Bright.
Fig. 1 is the difference upgrade method flow chart that embodiment of the present invention provides.As it is shown in figure 1, this
A kind of difference upgrade method of bright offer may include that
Step 101: obtain source resource bag and target resource bag；
Source resource bag and target resource bag can be stored in upgrade server.Those skilled in the art are permissible
Understand, at least source resource bag should be stored in upgrade server, target resource bag can when needed,
During for example, it is desired to use target resource bag to provide leak patch or function renewal, target resource is wrapped biography
In upgrade server, so that source resource bag and target resource bag are in the state that can be acquired.
Step 102: judge to there is difference instrument；
It will be understood by those skilled in the art that difference instrument, can for performing the necessary instrument of difference upgrading
To include difference job contract tool, to compare instrument and signature instrument etc..As a example by Android system, instrument list
Can be such that
Difference job contract tool:

out/host/linux-x86/framework/signapk.jar
Step 103: in the case of there is difference instrument, can be according to acquired source resource bag and mesh
Mark resource bag determines difference upgrading platform；
It will be understood by those skilled in the art that in source resource bag and target resource bag, preferably can comprise feature
Parameter indicates the information of the targeted platform of this resource bag, according to such characteristic parameter, and can be according to institute
The source resource bag obtained and target resource bag determine difference upgrading platform.
Step 104: according to acquired source resource bag and target resource bag, based on determined by difference liter
Level platform selecting difference instrument creates upgrading difference bag.
After step 101-103, it has been determined that and there is available difference in difference upgrading platform
Instrument, the condition required for difference is upgraded that therefore performs has been provided with, can be according to source resource bag and target
The content of resource bag, utilizes difference instrument to create upgrading difference bag.
In embodiments, the wave of time and memory space is caused in order to avoid repeating to create difference bag
Take, can first confirm whether upgrade server exists the difference bag created before creating difference bag.
Said process can be confirmed result by the characteristic parameter of resource bag by contrast.
Correspondingly, in embodiments, can perform after described acquisition source resource bag and target resource bag
Following methods step: resolve described source resource bag respectively and described target resource bag obtains characteristic parameter；Ratio
The characteristic parameter of more described source resource bag and the characteristic parameter of described target resource bag；When comparative result is phase
Meanwhile, determine and there is described upgrading difference bag；And extract described upgrading difference bag.Now, it is extracted
Upgrading difference bag be the upgrading difference bag utilizing difference instrument to create in the past.Owing to upgrade server is public
Server altogether, multiple users can submit target resource bag to upgrade server, accordingly, it is possible to occur
The most different users submits the situation of identical target resource bag to.In this case, based on after carry
The difference upgrading of the target resource bag handed over can directly utilize existing upgrading difference bag and carry out, and extracts
Upgrading difference bag is used directly for difference upgrading.
In embodiment of the present disclosure, the characteristic parameter of resource bag can include at least one of person:
Create mark, platform name and create type.Illustrating with Android system, features described above parameter is in Android system
System is designated: build.id, platform, build.type, respectively represent create mark, platform name with
And establishment type.
In embodiments, when getting source resource bag and target resource bag, extraction source money can be distinguished
Source bag and the establishment mark of target resource bag, platform name and establishment type, compare described source resource bag
Characteristic parameter and the features described above parameter of described target resource bag, when the features described above parameter of the two is identical
Time, it can be determined that upgrade server exists existing upgrading difference bag.Meanwhile, identify according to establishment,
Platform name and establishment type, can obtain the title of upgrading difference bag according to predetermined naming rule.Then,
Can search in upgrade server according to this title, thus find the upgrading difference bag of correspondence.
Correspondingly, it will be understood by those skilled in the art that and utilize the platform name in features described above parameter permissible
Determine the platform corresponding to resource bag.Therefore, in embodiments of the present invention, method may include that
Resolve described source resource bag respectively and described target resource bag obtains characteristic parameter (such as, platform name)；
And determine described difference upgrading platform according to obtained characteristic parameter.Additionally, according in characteristic parameter
Establishment type, it is also possible to determine the critical path of resource bag.
Finally, it is no matter newly created upgrading difference bag or the upgrading difference bag extracted all will be transmitted
To version server, for device upgrade.Correspondingly, said method also includes to be created or extracting
Upgrading difference bag be sent to the step of version server.
Fig. 2 is the difference upgrade-system structural representation that embodiment of the present invention provides.As in figure 2 it is shown,
