Embodiment

Many details are elaborated in the following description to fully understand the application.But, this Shen It is able to please be implemented with being much different from other manner described here, those skilled in the art can not disobey Similar popularization is done in the case of back of the body the application intension, therefore, the application is not by following public specific implementation Limitation.

In this application, a kind of access method and device to supporting layer software work(is each provided, it is a kind of right The upgrade method and device of supporting layer software function, and a kind of manager to supporting layer dynamic updating programe Method and device.It is described in detail one by one in the following embodiments.

In order to make it easy to understand, describing a kind of upgrade method to supporting layer software function of the application offer first Embodiment.Before the specific steps of description the present embodiment, first to the technical program and dynamic update journey The generating process of sequence does brief description.

The core of the technical program is：Mechanism is merged by process, by the dynamic update comprising upgrade code Program is injected into supporting layer service processes, and on this basis that the function of supporting layer corresponding function interface is real Modern code is set to the upgrade code, it is achieved thereby that light weight, dynamic update to supporting layer software function Mode, application program can then access the supporting layer software function after upgrading.With using tradition OTA modes pair System software upgrading compares, and this method only needs to merge by process and by the work(of corresponding function interface It can realize that code is set to upgrade code, you can realize the dynamic load of upgrade code, realize soft to supporting layer The upgrading of part function, thus in the case of the OTA performance difficulties there is provided it is a kind of efficiently, lightweight Supporting layer software function upgrade method.

Supporting layer described in the present embodiment, typically refers to provide for application program in system software layer architecture The software layer of service, wherein a series of set of storehouses, function or component is included, and by externally providing The mode of functional interface provides service to application program., can when application program needs to realize a certain systemic-function To access the corresponding function interface of supporting layer offer.By taking Mobile operating system Android or YunOS as an example, The supporting layer that service is provided for application program can be ccf layer (framework), and supporting layer functional interface can be with It is the functional interface that the component in ccf layer is provided.

In order to realize the upgrading to supporting layer software function, in specific implementation, first it can be obtained from service end Dynamic update software kit and the dynamic updating programe executable by installing generation.Implementing to be： Software kit, which is sent, to service end obtains request, software kit of the acquisition request for supporting layer software function of upgrading； The acquisition of information dynamic update software kit provided according to service end；Can by installing the software kit obtained generation The dynamic updating programe of execution.Wherein, the service end can be high in the clouds.

Exemplified by implementing in Android operation system, service end can connect for ccf layer function to be upgraded The corresponding upgrade code of mouth generation, and dynamic update software kit is made, typically suffix is apk software kit； Implement the mobile device of this method (for example：Smart mobile phone) can according to certain strategy, such as periodically, The request for obtaining the software kit for being used for upgrade framework layer software function is sent to service end, can be with the request The information such as carried terminal type, original software kit version number；Service end is received after request, and inquiry is believed with terminal Breath matching, the dynamic update software kit that is available for mobile device update, and mobile device is pointed out from corresponding Website download；The information that mobile device is provided according to service end is downloaded and installs dynamic update software kit, this Sample just generates executable dynamic updating programe, contained in the program for realize ccf layer some or The upgrade code of the upgrade function of some functional interfaces.

Preferably, Function Extension software kit can also be obtained from service end and is installed and is generated as dynamic update journey Sequence provides the Function Extension program of Function Extension service.In order to realize the technical program, it is necessary to by dynamic update Program is injected into supporting layer service processes, and supporting layer service processes generally play maintenance in an operating system The effect of application execution environment, in order to ensure the stable operation of supporting layer service processes, dynamic update journey The minimal set for the upgrade code for needing to perform dynamic replacement can be only included in sequence, and branch need not be operated in Function in support layer service processes transfers to the Function Extension program run outside supporting layer service processes to realize, And the upgrade code that dynamic updating programe is provided, then the function expansion that can be provided by calling function extender Open up interface, using the expansion service that it is provided, required function can be both realized, while also protecting to greatest extent The stable operation of supporting layer is demonstrate,proved.

Based on above-mentioned consideration, host equipment can be obtained in the lump while above-mentioned acquisition dynamic update software kit Function Extension software kit is taken, and by installing the software kit obtained, generation dynamic updating programe, Yi Jiwei Dynamic updating programe provides the Function Extension program of Function Extension service.

So far, the generating process to the technical program and dynamic updating programe (and Function Extension program) is entered Explanation is gone.In the specific implementation, when installing first and generating dynamic updating programe, Ke Yisui The step 101 and 102 in examples provided below is performed afterwards, for updating the in the case of of installation, then can be carried Show user's restarting systems, and the step 101 and 102 is performed in system initialization process, so that real The upgrading of existing supporting layer software function.Below exemplified by implementing this method in system initialisation phase, to this Shen A kind of embodiment for the upgrade method to supporting layer software function that please be provided is described in detail.

With reference to Fig. 1, it is a kind of flow of the embodiment of upgrade method to supporting layer software function of the application Figure, methods described comprises the following steps：

Step 101, operation include the dynamic updating programe of upgrade code, and merge mechanism by described in by process Dynamic updating programe is injected into supporting layer service processes.

In the specific implementation, generally can be initial in the system (hereinafter referred to as host system) for implementing this method Implement this method during change, for example, in initial phase can trigger this method by supporting layer service processes Perform, so as in the initial phase of host system, just complete the dynamic update of supporting layer software function, The access request to supporting layer functional interface that application program is then initiated, it is possible to the reality having access to after upgrading Modern code.Illustrated below exemplified by implementing on the mobile device using android system.

Dynamic updating programe can be by accessing the modes such as configuration file in advance to the following demand of system registry：Connect Receive the presetting message of system initialisation phase；After mobile device startup, android system performs standard boot Flow, successively Bootloader (bootloader), kernel and ccf layer service processes, ccf layer service into Journey can broadcast the presetting message in initial phase, be connect because dynamic updating programe is registered in advance The demand of the presetting message is received, therefore ccf layer service processes will trigger the execution of this method, operation is dynamic State ROMPaq, so that dynamic updating programe can just receive the presetting message.Described here preset disappears Breath typically refers to the message that ccf layer service processes are broadcasted in system start-up phase, for example, can be that start is completed Message or other message.

This method is triggered after execution, and this step is first carried out：Operation includes the dynamic update journey of upgrade code Sequence, and the dynamic updating programe is injected into supporting layer service processes by process merging mechanism.It is described Process merges mechanism and referred to, multiple independent programs or application component is operated according to configuration rule same The Task Scheduling Mechanism of operating system process.At present, main flow Mobile operating system generally can to program or The process title of application component is specified, so as to allow different program or application component to operate in together In one process.

Can (be usually AndroidManifest.xml in configuration file by taking Android Mobile operating systems as an example File, also referred to as describes file) in the process title that program or application component are run is specified.In order to Readily appreciate, the configuration file fragment of two independent system components is set forth below：

The configuration file fragment of system component 1：

The configuration file fragment of system component 2：

Wherein, com.android.comp1 and com.android.comp2 is two independent system components, is referred to Fixed process title is identical, is com.android.merged, then when running the two system components, System can lookup names for com.android.merged process (if creating entering for the title without if Journey), and the two system components are all operated in the process.

Based on above-mentioned principle, operation institute can be specified in advance in the configuration file of the dynamic updating programe The process title for stating dynamic updating programe is consistent with supporting layer service processes, then running the dynamic update During program, it is possible to merge mechanism by process so that dynamic updating programe is run with supporting layer service processes In the same process space, i.e.,：Dynamic updating programe comprising upgrade code is injected into supporting layer service It is that the progress dynamic replacement of subsequent step 102 is ready in process.

It should be noted that being abused in order to avoid above-mentioned process merges mechanism, some Mobile operating systems lead to The implementation that Chang Huiwei processes merge mechanism sets some constraintss, therefore in the specific implementation, except with Document is put calmly and outside supporting layer service processes identical process title, can also carry out extra operation expires The constraints of sufficient Mobile operating system, for example：Dynamic updating programe is consistent with the digital signature of supporting layer, The operating system user identifier (ID) specified for dynamic updating programe is mutually equal with supporting layer.

This step merges mechanism by process, the dynamic updating programe comprising upgrade code is injected into supporting layer In service processes, not only subsequent execution dynamic replacement ready for operation, and moving operation will not be broken The original integrality of system, can provide powerful guarantee for the safe operation of whole system.

Step 102, the function of supporting layer functional interface to be upgraded realized that code is set to upgrade generation accordingly Code.

Perform after step 101, the dynamic updating programe comprising upgrade code has been injected into supporting layer service In process, it is corresponding that the function of supporting layer corresponding function interface is then realized that code is set to have been injected into by this step Upgrade code.

The upgrading generation of several functional interfaces to be upgraded in supporting layer is generally comprised in the dynamic updating programe Code, the upgrade code is to realize code to what corresponding function interface realization of functions was upgraded, is typically Executable code, is referred to as object code., will for supporting layer for some functional interface to be upgraded Its function realizes that code is set to after the corresponding upgrade code in dynamic updating programe, when application program initiation pair After the access request of the functional interface, supporting layer carries out upgrade code, so that application program can just be visited The supporting layer software function after upgrading is asked, i.e.,：Realize and supporting layer software function is redefined.

The function of supporting layer functional interface is realized that code is set to upgrade code, the angle realized from technology can So that two ways is replaced or redirected using code, in the present embodiment and subsequent embodiment, it will use Code substitute mode or redirection mode, the function of functional interface realized that code is set to accordingly upgrade generation The process of code is referred to as dynamic replacement.Both modes are illustrated separately below.

(1) code is replaced, i.e.,：The original of functional interface to be upgraded is realized that code is directly replaced with accordingly Upgrade code.For example, realizing that the code of the functional interface, for A, was included in dynamic updating programe originally Corresponding upgrade code is A ', then this step can use A ' replacement A, if hereafter receiving application program to institute The access of functional interface is stated, actual execution is then A '.

(2) redirect, i.e.,：Do not perform code replacement operation, but the visit that upgrade function interface will be treated Ask and be redirected to corresponding upgrade code.For example, the function reality for storing the functional interface can be changed The pointer value of modern code first address so that the pointer points to the corresponding upgrade code in dynamic updating programe, from And if receive access of the application program to the functional interface, will be performed according to the sensing of the pointer corresponding Upgrade code.

In the specific implementation, above-mentioned redirecting technique can be realized in different ways, in the present embodiment Realized, exemplified by implementing in android system, can used based on Java aspects using Hook modes Hook modes, are realized and are redirected using the characteristic of virtual machine and Java reflex mechanism, it would however also be possible to employ base In the Hook modes of primary aspect (Native), by parsing ELF (Executable and Linkable Format - can perform linking format) file realization redirection.

It should be noted that the operation of this step can be performed by supporting layer service processes, can also be by dynamic ROMPaq is completed.In the latter case, dynamic updating programe not only includes upgrade code, also comprising holding The code of Mobile state replacement function, exemplified by implementing this method in system initialisation phase, supporting layer service into Journey operation state ROMPaq, and dynamic updating programe merging is run in supporting layer service processes, dynamic ROMPaq is after its presetting message registered in advance is received, it is possible to perform dynamic replacement operation：Search The upgrade code of which functional interface is included in dynamic updating programe, and is entered one by one for these functional interfaces Mobile state is replaced, and function is realized into code is set to corresponding upgrade code.

So far, by above-mentioned steps 101-102, the upgrading to supporting layer software function provided the present embodiment The embodiment of method is described in detail.

If it should be noted that the upgrade code that dynamic updating programe is included needs access function upon execution The Function Extension service that extender is provided, and installed before this method is implemented in triggering and generate work( Energy extender, then the Function Extension program run outside supporting layer service processes, example can also be started Such as：Start the Function Extension program in the independent process different from supporting layer service processes.

In the specific implementation, the opportunity of startup function extender is that comparison is flexible, as long as can be dynamic ROMPaq provides Function Extension service and is just all possible.For example：Function Extension program can also be noted in advance Volume needs to receive the presetting message of initial phase, then supporting layer service processes can be in initial phase Startup function extender；Or the upgrade code included in dynamic updating programe needs access function extension clothes In the case of business, call and open by IPC (Inter-Process Communication-inter-process communication mechanisms) Dynamic Function Extension program；Or Function Extension program according to timer, network state change etc. trigger condition from Row startup optimization is also possible.

In summary, the upgrade method to supporting layer software function that the present embodiment is provided, not using tradition OTA modes are upgraded to supporting layer software function, but by the upgrading of the functional interface to be upgraded of supporting layer Code is included in dynamic updating programe, and then merge mechanism by process is injected into supporting layer by upgrade code The upgrading of supporting layer software function is realized in service processes and by dynamic replacement, in OTA performance difficulties In the case of there is provided a kind of supporting layer software function upgrade method of lightweight, so as to timely, fast Upgrade promptly supporting layer software function, meet the requirements for access of application program.

The access request of step 301, reception application program to supporting layer functional interface.

The supporting layer functional interface refers to the supporting layer functional interface being upgraded in the present embodiment, i.e.,： Its function realizes that code has been arranged to the corresponding upgrade code that dynamic updating programe is included.When application program hair After rising to the access request of the functional interface, this step can just receive the access request.

By taking android system as an example, each component in ccf layer can externally provide one or more work( Energy interface, when application program needs the Functional Capability of access some component offer (for example：Call, obtain Take international mobile equipment identity number etc.) when, the access request to corresponding function interface can be initiated, ccf layer service processes are just The access request can be received.

Step 302, execution correspond to the upgrade code of the functional interface.

Because the function of the functional interface realizes that code is already set as corresponding upgrade code, therefore this The upgrade code for corresponding to the functional interface that step is performed, so as to provide upgrading for application program Supporting layer software function afterwards.In the specific implementation, can also be by the upgrading after this step has been performed The implementing result of code returns to the application program.

Preferably, during the upgrade code corresponding to the functional interface is performed, in addition to：Call The Function Extension interface that the Function Extension program run outside the supporting layer service processes is provided.Wherein, The Function Extension program, is the executable program generated in host system after installation function extended software bag, The Function Extension software kit is obtained in the lump when obtaining the dynamic update software kit from the service end.

For example, the upgrade code of the functional interface, which is realized, obtains mobile device international mobile equipment identity number (mobile device state Border identification code) function, in order to provide security guarantee, in addition it is also necessary to whether there is corresponding acquisition to requesting party Authority checked, and scope check function is by the Function Extension program run outside supporting layer service processes Realize, in such a case, it is possible to include the authority provided Function Extension program in the upgrade code Check interface calls code, then this step is when performing the upgrade code, it is possible to correspondingly perform To the call operation of scope check interface, and inside Function Extension program, corresponding Function Extension code is carried out Scope check, the result that upgrade code is then returned according to Function Extension program decides whether can be to application program International mobile equipment identity number is provided and handled accordingly.

In order to make it easy to understand, diagrammatically providing a specific example herein, Fig. 4 is referred to, it is Supporting layer service processes receive the processing procedure schematic diagram after application program access request, the reality provided in Fig. 4 Apply in mode, the function of functional interface 1 is realized that code is set to corresponding liter using redirection mode in advance Level code.Wherein operation 1 represents access of the supporting layer service processes reception application program to functional interface 1 and asked Ask, operation 2 represents the upgrade code of supporting layer service processes perform function interface 1, operation 3 represents described The Function Extension interface 1 that upgrade code calling function extender is provided realizes required function.

It is above-mentioned to give the example that upgrade code calls One function expansion interface, in the specific implementation, if The need for a certain Function Extension interface that Function Extension program is provided can not meet upgrade code, upgrade code is also Other the multiple Function Extension interfaces that can be provided with calling function extender, i.e. access function extender is carried The multiple functions of supplying are realized, can also call the API of other processes or component offer.

In the specific implementation, the call operation for the Function Extension interface that upgrade code is provided Function Extension program, It can be realized using IPC mechanism.If Function Extension program not yet starts, it can be called and opened by IPC Dynamic Function Extension program, then visits again required Function Extension interface.

, can some are complicated or nothing using the preferred embodiment of above-mentioned access function expansion interface The function that method makes accurate evaluation to operation stability transfers to Function Extension program to complete, due to Function Extension journey Sequence is run outside supporting layer service processes, therefore supporting layer can both use the clothes that Function Extension program is provided Business, can ensure the stable operation of its own again.

So far, access being provided by above-mentioned steps 301-302 the present embodiment, to supporting layer software function The embodiment of method is described in detail.By foregoing description as can be seen that using the above method, by In after access request of the application program to supporting layer functional interface is received, work(is not performed in a conventional manner The original of energy interface realizes code, but performs and merge the upgrading generation that mechanism is injected after simultaneously dynamic replacement using process Code, i.e. in the case where no use tradition OTA modes carry out system software upgrading, application program is still The supporting layer software function that can be had access to after upgrading is more perfect so as to provide the user in time Function, can also accordingly lift the usage experience of user.

In the above-described embodiment there is provided a kind of access method to supporting layer software function, in contrast Answer, the application also provides a kind of access mechanism to supporting layer software function.Fig. 5 is refer to, it is this Shen A kind of schematic diagram of the embodiment of access mechanism to supporting layer software function please.Due to device embodiment base This is similar in appearance to embodiment of the method, so describing fairly simple, referring to the part of embodiment of the method in place of correlation Explanation.Device embodiment described below is only schematical.

A kind of access mechanism to supporting layer software function of the present embodiment, including：Access request receiving unit 501, for receiving access request of the application program to supporting layer functional interface；Upgrade code execution unit 502, For performing the upgrade code corresponding to the functional interface comprising the dynamic of the upgrade code rises Level program merges mechanism by process and is previously implanted into supporting layer service processes, and the functional interface Function realize that code is arranged to the upgrade code.

Optionally, described device also includes：

In addition, the application also provides a kind of management method to supporting layer dynamic updating programe.Because movement is set Standby software version, which is realized, to differ greatly, and the dynamic updating programe for supporting layer software function of upgrading there may be With host system it is incompatible the problem of, then operation state ROMPaq simultaneously perform dynamic replacement operation after, can Host system can be caused normal work or even can not start normally.For this problem, the application is proposed The management method to supporting layer dynamic updating programe, compatibility can be detected and detected not Dynamic updating programe is unloaded when compatible, so that the supporting layer software function light weight upgrade technique proposed to the application Scheme, there is provided a kind of fault detect and Restoration Mechanism, is the useful supplement to the technical scheme.

Fig. 6 is refer to, a kind of reality of its management method to supporting layer dynamic updating programe provided for the application Apply the flow chart of example.The present embodiment is repeated no more with above method embodiment step identical part, below weight Point description difference.A kind of management method to supporting layer dynamic updating programe of the present embodiment includes as follows Step：

Step 601, judge whether the dynamic updating programe for supporting layer software function of upgrading is simultaneous with host system Hold, if compatible, perform step 603, otherwise, perform step 602.

The dynamic updating programe and host system are incompatible can the different forms of expression, thus judge be It is no it is incompatible can also in different ways, the present embodiment enumerates two kinds：

1) judge the upgrade code that is included with the dynamic updating programe perform dynamic replacement operation whether return table The successful result of operation is levied, if it is not, then judging that the dynamic updating programe and host system are incompatible.

For example：Functional interface corresponding with upgrade code is not present in supporting layer, or, upgrade code is related to And suction parameter realize that the suction parameter that code is related to is mismatched with original, lead to not carry out dynamic replacement, Now dynamic replacement operation can all return to failure result, in this case, although without result in system reboot, It can also judge that the dynamic updating programe is mismatched with host system.

2) information is started according to the history of the dynamic updating programe, judged due to using the dynamic updating programe Comprising upgrade code perform dynamic replacement operation, cause whether the situation of system reboot meets preparatory condition, If so, then judging that the dynamic updating programe and host system are incompatible.

In the specific implementation, can be in the start-up course of dynamic updating programe, the record number of starts simultaneously will The starting state of dynamic updating programe is set to start；Dynamic replacement operation if successfully completed, then The starting state of dynamic updating programe can be set to start successfully, and record this time startup successfully related letter Breath.The history of the dynamic updating programe recorded using aforesaid way starts information, can be risen as dynamic is judged Level program foundation whether compatible with host system.

Because dynamic updating programe is generally run in the initial phase of host system and performs dynamic replacement behaviour Make, thus can host system initial phase, have not carried out dynamic replacement operation before to compatibility Judge, implementing to be：Read from the history startup information recorded on dynamic updating programe Starting state once, if the starting state is " starting ", illustrates to move because the last time performs State replacement operation result in host system this restart.If causing system due to performing dynamic replacement operation The situation restarted meets preparatory condition, then can be determined that dynamic updating programe is incompatible with host system.For example： If causing the number of times of system reboot to be more than predetermined threshold value (for example due to performing dynamic replacement operation：3 times), It then can be determined that dynamic updating programe is incompatible with host system.

In the specific implementation, when performing above-mentioned judgement, above-mentioned history can also be considered and started in information Startup total degree, the successful history relevant information of startup of the dynamic updating programe of record etc., and can set Put different preparatory conditions.

If it is judged that being：Dynamic updating programe is incompatible with host system, can cancel dynamic and replace Change operation, it is ensured that host system normally can start and run；Otherwise, dynamic replacement behaviour can normally be performed Make to realize the upgrading to supporting layer software function.

The compatible two ways for judging dynamic updating programe and host system is presented above, specific real Other judgment modes different from aforesaid way can also be used by applying.If it is determined that dynamic updating programe and host System is incompatible, then goes to step 602 and perform.

Step 602, the unloading dynamic updating programe.

Go to this step and illustrate that dynamic updating programe is incompatible with host system, in such a case, it is possible to Unload dynamic updating programe.Implementing to be：Point out dynamic updating programe and host system described in user It is incompatible, and the dynamic updating programe is unloaded according to the instruction of user.

If being mounted with to provide the Function Extension journey of expanded function service for dynamic updating programe in host system Sequence, then, can be with offloading functions extender while dynamic updating programe is unloaded.

In addition, in the specific implementation, if the judgement dynamic updating programe of step 601 and host system be not simultaneous Hold, can also collect and generate the correlation log information for recording incompatible state, and by the log information Pass to the service end that dynamic update software kit (installation kit of dynamic updating programe) is provided.The log information It can include：Dynamic replacement failure cause, the dynamic updating programe number of starts, the context letter at failure scene Breath etc..Service end can be analyzed according to the log information received, position failure cause, and eliminate failure The dynamic update software kit of redaction is made afterwards and mobile device is supplied to, so that mobile device can successfully rise Level supporting layer software function.

Step 603, the reservation dynamic updating programe.

Go to this step and illustrate that dynamic updating programe is compatible with host system, therefore the dynamic can be retained ROMPaq, without performing unloading operation.

So far, the manager to supporting layer dynamic updating programe provided by step 601-603 the present embodiment The embodiment of method is described in detail.By foregoing description as can be seen that the management method is provided A kind of Failure detection and recovery method for dynamic updating programe, is detecting dynamic updating programe and host It when system is incompatible, can be retracted by unloading dynamic updating programe, ensure the normal fortune of host system OK.

In the above-described embodiment there is provided a kind of management method to supporting layer dynamic updating programe, therewith Corresponding, the application also provides a kind of managing device to supporting layer dynamic updating programe.It refer to Fig. 7, It is a kind of schematic diagram of the embodiment of managing device to supporting layer dynamic updating programe of the application.Due to Device embodiment is substantially similar to embodiment of the method, so describing fairly simple, related part is referring to method The part explanation of embodiment.Device embodiment described below is only schematical.
