Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Owing to people are more and more higher to the performance requirement of terminal, the chamber of commerce of factory may make multiple version for the terminal of same model, simultaneously again in order to realize being upgraded to target version by disposable for current version, it is necessary to make each version difference AKU to target version.Such as: target version is upgraded to V5 by V4 at present, then production firm just needs at server end existing V2-V1, V3-V1, V4-V1, V3-V2, V4-V2, on the basis of V4-V3 difference AKU, increase configuration V5-V1, V5-V2, V5-V3, these four difference AKUs of V5-V4, thus the terminal use of each version can pass through to download corresponding difference AKU, it is achieved the disposable target version that is upgraded to, but this upgrade method makes production firm need to make substantial amounts of difference AKU.If target version is Vn(n is positive integer), then production firm needs to make n (n-1)/2 kind of difference bag, and development cost is big.
Therefore, for upgraded version span bigger time, the method adopting the many bags of OTA to upgrade continuously, is namely upgraded to target version from the version that present terminal is currently in use through intermediate releases continuously, and such production firm has only to make the difference AKU of the version with low one-level for each latest edition.Such as: target version is upgraded to V5 by V4 at present, production firm just needs at server end existing V2-V1, V3-V2, on the basis of V4-V3 difference AKU, increase configuration this difference AKU of V5-V4, reduce the quantity of the AKU needing making and test, reduce production cost.
For above many bags upgrade method, the present invention proposes the method for calibration that the many bags of a kind of OTA are upgraded continuously, system fingerprint information in terminal is stored under system partitioning and system subregion, so when many bags are upgraded continuously, as long as copying the patch file (patch file is that the boot subregion of target version and recovery subregion are relative to the differential file at first version) in difference bag to system subregion.At this moment system subregion has been upgraded, it is not necessary to start, the system fingerprint information in system subregion is changing to the system fingerprint information of target version.Thus can be avoided must start shooting in prior art could become the system fingerprint information of target version by the system fingerprint information in internal memory, and once system fingerprint information is not mated to cause and verified unsuccessfully, exit many bags and upgrade continuously and then cause whole upgrading unsuccessfully.
Consult the method for calibration of the many bag upgradings of a kind of OTA that Fig. 2, Fig. 2 provide for the embodiment of the present invention, as in figure 2 it is shown, described method of calibration includes:
Step 201, is read-only by the system partitioning carry of terminal, and obtains the system fingerprint information in the system partitioning being pre-stored within described terminal.
Wherein, system fingerprint information refers to the finger print information of the currently used system version of terminal, including terminal brand, implementor name, system version number, revision ID, internal control version number, release type, etc. relevant information.
Concrete, before step 201, the chamber of commerce of factory makes different difference AKUs and uploads onto the server, and server receives the AKU of the latest edition that developer makes, by whether prompting terminal carries out system upgrade.
Further, if terminal selects to carry out system upgrade, or terminal use selects to start OTA client and carries out system upgrade, as shown in Figure 3, OTA client initiates the detection of system upgrade according to the request of terminal use, the control of trigger server end returns strategy 301, and the strategy of setting is returned to OTA client 302 according to the upgrading mode arranged, facility information and present terminal version number by server.The information of multiple AKUs that OTA client returns according to server end, is shown on terminal interface by the version number of latest edition, version information, all AKU size summations 303.Judge whether 304 users select to download, if user selects to download, continue to judge that whether the memory space of 305 current phone is sufficient, if abundance, successively the whole AKUs needed for from currently used edition upgrading to target version are downloaded to terminal 306, if inadequate, prompting user's space is not enough, exits upgrading 307.
Further, after all AKUs that upgrading is required are downloaded to terminal by OTA client, upgrading mode, AKU path and many bags mark are write in cache subregion by OTA client, but recovery pattern is not necessarily capable of identify that the AKU path that upper layer transfers is got off, it is thus desirable to increase the interface of path integration at framework layer, according to the standard specified with memorizer, it is the path 308 that may identify which under recovery pattern by AKU path integration.
Further, after path integration completes, require over cache subregion and as medium AKU path passed to recovery, and the information such as upgrading mode, AKU path are write/cache/recovery/command in, perform to reboot into recovery pattern 309.
It should be noted that in whole downloading process, the only one of which progress bar that user sees, the form of many bags is completely invisible to user, and Consumer's Experience is effective.In downloading process, if occurring, the situations such as Network Abnormal cause failed download, then, when next time connects network, it is possible to carry out automatic continuous according to the download of last time and descend load, after having downloaded, prompting user upgrades.
Further, terminal obtain from currently used edition upgrading to target version needed for the method for all AKUs can also be: terminal to server sends the update request message carrying current version, server obtains the current version of terminal according to update request message, and detect target version, current version being upgraded to all AKUs needed for target version transmit to terminal, terminal receives all AKUs that server sends.Can also is that user manually downloads all AKUs being upgraded to target version from current version from server.
It is upgraded to all AKUs of target version each AKU from current version includes two versions it should be noted that download from server: in first version and redaction.Wherein, can be the AKU between adjacent two versions at first version and redaction, can also being the AKU of non-conterminous two versions, be used for indicating this AKU needs which version is upgraded at first version, redaction be then for indicating terminal staging to which version according to this AKU.What necessarily have an AKU in all AKUs downloaded is the currently used version of terminal at first version, and the redaction necessarily having an AKU is target version, and the prototype version of redaction another AKU corresponding of an AKU.
The method of calibration schematic flow sheet that Fig. 4 upgrades continuously for the many bags of another kind of OTA that the embodiment of the present invention provides, as shown in Figure 4, after entering recovery pattern, terminal resolves 401 by performing get_args (&argc, the upgrading desired parameters such as the routing information of OTA AKU that &argv) obtains, version number, it is judged that whether 402 resolve to and wrap upgrading more.
Concrete, can when making OTA AKU, original basis making the mono-bag of OTA increases many bags identification parameter in triggering script multi-ota-inc-update.sh, and increase the parsing to many bags identification parameter in performing script ota_from_target_files, so when performing OTA upgrading, due to upgrade parameter all of before upgrading all be written into/cache/recovery/command in, it is therefore desirable to whether judgement/cache/recovery/command exists many bags identification parameter.Can also increase the dissection process script in multi territory in misc subregion, so when performing OTA upgrading, by the multi territory of parsing misc subregion being single bag or wrapping more, to determine that carrying out single bag verifies or wrap verification more.
Further, if there is many bags identification parameter, then many bags checking process is entered；If being absent from many bags identification parameter, then enter single bag checking process 100, as it is shown in figure 1, from tag memory obtain system fingerprint information, and with the system fingerprint information matches in the AKU read from depositor, if coupling, then verifying successfully, entering upgrading flow process, if not mating, then verify failure, stop upgrading.
Further, 403 are obtained at the first version number i-th AKU identical with currently used version number according to the version number of currently used system version.Wherein, i represents which currently acquired AKU, it is possible to take 1,2,3 ... n, n are the number from the currently used edition upgrading of terminal to the AKU of target version.Load i-th AKU, to obtain the system fingerprint information in 404 i-th AKUs, and this system fingerprint information is stored in a register.Wherein system fingerprint information includes the finger print information of the version to upgrade in the finger print information of current version and i-th AKU.
Further, affect follow-up updating operation in order to avoid the device attribute in system subregion is easily modified, be read-only operation by system subregion carry 405.Load the build.prop file in system subregion, wherein build.prop file includes the property value of all parameters of system version, traversal build.prop file is to obtain the row at the property value place of the system fingerprint information of terminal line by line, obtain the system fingerprint information in 406 these row, for follow-up verification.
Step 202, based on the check results of system fingerprint information acquired in the system partitioning from described terminal with the system fingerprint information in the OTA AKU read from depositor, to judge whether to the many bag upgradings of OTA.
It should be noted that OTA AKU here refers to OTA difference AKU, wherein OTA difference AKU is contrasted, by the AKU according to two adjacent versions, the AKU that the difference information of gained forms.Example, difference AKU V2-V1 contains version V2 relative to the version V1 application message changed, to realize upgrading by difference AKU V2-V1, the current version of terminal is necessary for V1, and the version of rear client of having upgraded just becomes V2.
Concrete, read the system fingerprint information of i-th AKU in depositor, to judge whether 407 mate with the system fingerprint information obtained from terminal system subregion, if coupling, then verify successfully, terminal enters upgrading flow process 408, i-th AKU being upgraded, if not mating, then verifying failure, exiting upgrading 409, terminal remains as currently used version.
Further, after terminal enters the upgrading flow process 408 of i-th AKU, unload system subregion, by under the patch file copy in i-th AKU to system subregion.Wherein patch file is that the boot subregion of the redaction in i-th AKU and recovery subregion are relative to the differential file at first version in i-th AKU.At this moment system subregion has been upgraded, and the system fingerprint information in system subregion is changing to the system fingerprint information of redaction.
Further, if i-th AKU upgrades successfully, then continue to judge that whether i is less than n, wherein n is the number from the currently used edition upgrading of terminal to the AKU of target version, namely judge whether i-th AKU is last AKU, if not then continuing to obtain from acquired all AKUs in the version number of first version i+1 the AKU identical with the version number of redaction in i-th AKU, execution step 201, obtain the system fingerprint information in terminal system subregion.The finger print information of wherein acquired system partitioning is the finger print information of the redaction in i-th AKU.The system fingerprint information of the system fingerprint information in this system partitioning with i+1 the AKU read from depositor is mated.If coupling, then verify successfully, unloading system subregion, and by under the patch file copy in i+1 AKU to system subregion, wherein patch file is that the boot subregion of redaction in i+1 AKU and recovery subregion are relative to the differential file in first version (i.e. redaction in i-th AKU).At this moment system subregion has been upgraded, it is not necessary to start, the system fingerprint information in system subregion becomes the system fingerprint information of the redaction in i+1 AKU.
Further, it is judged that whether i+1 AKU is last AKU, if not then continuing to obtain next AKU, then perform step 201 and step 202 successively, this AKU is verified, until verifying to last AKU.If verifying successfully, then by under the patch file copy of redaction in last AKU to system subregion, perform finish_recovery (), upgrade status flag bit is write in cache/recovery/status, delete the AKU on memorizer, empty misc subregion, and delete/cache/recovery/command.Starting starting procedure, by the patch file copy in system subregion to recovery subregion, terminal is upgraded to the redaction in last AKU by current version.
Further, in whole upgrading flow process 408, once occur that the system fingerprint information of terminal is not mated with the system fingerprint information in AKU, then verifying failure, exiting upgrading, after starting starting procedure, terminal is simply upgraded to the redaction in previous AKU.
Example, terminal current version is V1, and target version is V4, if terminal request is upgraded to target version V4, server can for terminal configuration by all AKUs of V1 to V4, and including V2-V1, V3-V2, V4-V3, then terminal receives above-mentioned all AKUs.Obtain the first AKU V2-V1, perform step 201 and step 202, it is thus achieved that the system fingerprint information in the system subregion of terminal, to mate with the system fingerprint information of V2-V1 AKU in the depositor read, if not mating, then verify failure, exiting upgrading, terminal remains as V1 version.
Further, if coupling, then verify successfully, unload system subregion, by under the patch file copy in V2-V1 AKU to system subregion.Wherein patch file is the boot subregion of V2 version and the recovery subregion differential file relative to V1 version.At this moment system subregion has been upgraded, it is not necessary to start, the system fingerprint information in system subregion is changing to the system fingerprint information of V2 version.
Further, judge that the first AKU is not last AKU, then continue to obtain the second AKU V3-V2, perform step 201 and step 202 successively, obtain the system fingerprint information in the system partitioning of terminal, the i.e. finger print information of V2 version, mates with the system fingerprint information with V3-V2 AKU from depositor.If not mating, then verifying failure, exiting upgrading, terminal is simply upgraded to V2 version.
Further, if coupling, then verify successfully, unload system subregion, by under the patch file copy in V3-V2 AKU to system subregion.Wherein patch file is the boot subregion of V3 version and the recovery subregion differential file relative to V2 version.At this moment system subregion has been upgraded, and the system fingerprint information in system subregion is changing to the system fingerprint letter of V3 version.
Further, judge that the second AKU is not last AKU, then continue to obtain the 3rd AKU V4-V3, perform step 201 and step 202 successively, obtain the system fingerprint information in the system partitioning of terminal, the i.e. finger print information of V3 version, mates with the system fingerprint information with V4-V3 AKU from depositor.If not mating, then verifying failure, exiting upgrading, terminal is simply upgraded to V2 version.
Further, if coupling, then verify successfully, unload system subregion, by under the patch file copy in V4-V3 AKU to system subregion.Wherein patch file is the boot subregion of V4 version and the recovery subregion differential file relative to V3 version.At this moment system subregion has been upgraded, it is not necessary to start, and the system fingerprint information in system subregion is changing to the system fingerprint letter of V4 version.Judging that the 3rd AKU is as last AKU, then start starting procedure, by the patch file copy in system subregion to recovery subregion, terminal is by V1 edition upgrading to V4 version.
