In other SE media, when alleviation user is applied using NFC-SIM card downloading card as a result, the problem of SE insufficient space.
Further description is made to the preferred embodiment of the present invention with reference to the accompanying drawing.
As shown in fig.3, system architecture mainly consists of three parts in the embodiment of the present invention: TSM, terminal and card.
TSM manages platform as card issuer's trusted service, is mainly responsible for and is managed collectively to user, SE resource, completes
Using audit and publication, the operations such as application program downloading, individualized processing are provided for user.
Terminal in the embodiment of the present invention, joined SE management module, the major function of SE management module is such as in the terminal
Under:
Firstly, detection function.Specifically for the SE information in detection, all card slots of reading terminals, and recorded.
So-called SE information includes: SE type (whether NFC-SWP card), NFC unique identifier (SEID), free memory
Size, publisher's information, the SE application information downloaded etc., wherein the SE application information downloaded at least wraps
It includes Apply Names, application type, application size, frequency of usage, whether be shared Applet, Applet storage location, individualized
Data storage location.
Secondly, preserving distributed storage rule, when downloading application program, based on distributed storage rule, selection will
Application program is stored on SE1 or on SE2.
Again, data are carried out during to application procedure operation to synchronize.
Using application program in use, Applet and personal data to application program are matched, to complete to answer
The operation such as use with program.
Finally, the Applet of application program and personal data are stored separately.
Application program is being called to carry out operation and in use, needing to cache Applet, to complete application program
Operating process.Application program can be buffered in the OS layer of terminal, it can be temporarily stored in SE2；It can also be temporarily stored in
In the SE1 of NFC-SIM card.
Card is divided into main card (being denoted as SE1) and vice card (being denoted as SE2), wherein main card SE1 is that NFC-SIM card (is located at SE1
In card slot), vice card SE2 can be NFC-SIM card, be also possible to other SE Card Types (such as NFC-SD card) etc..
It, can be based on following principle setting distributed storage rule: carrying out using downloading and installation in the embodiment of the present invention
When, it can be carried out according to preset application memory rule for the distributed storage of SE1, SE2.Assuming that SE1 is NFC-SIM
Block (main card), SE2 is that SD card (vice card) can be stored in SE1 by certain applications for the memory space for rationally utilizing SE1
Applet, it is all apply personal data；The Applet of remaining all application is stored in SE2.Specific distributed storage rule
It will be introduced in subsequent embodiment.
Based on above system framework, as shown in fig.4, in the embodiment of the present invention, tool that terminal is managed the space SE
Body mode is as follows:
Step 400: in application program downloading process, the personal data of application program is stored in main SE by terminal,
And the logical data (i.e. Applet) for meeting the application program of the first preset condition is stored in main SE, first will not met
The logical data of the application program of preset condition is stored in secondary SE.
Specifically, the first preset condition has included at least any one in following rule or has appointed in the embodiment of the present invention
Meaning combination:
If a) logical data of application program is shareable data, the logical data of application program is stored in main SE
In (i.e. SE1), so-called main SE is the element for carrying NFC function, such as NFC-SIM card；
In practical application, certain logical datas can share a few set personal datas, to be packaged into different application journeys
Sequence, therefore, it is necessary to can deposit in SE1 for needing logical data to be sharing.
If b) being provided with following rule for the application program of specified type: the application program of same type in the same time
An application program is allowed to be activated；The application logic data being activated in the specified type are then stored in main SE
In, the logical data of other applications in the specified type is stored in secondary SE.
Specifically, in the embodiment of the present invention distributed storage can also be carried out according to Application Type.Optionally, portion
The application program of classifying type only allows to have within the same time application program to be activated (example in the application program of same type
Such as, financial class application program can only activate an application program simultaneously), therefore, it can will be swashed in the application program of this type
Application program living is stored in SE1, and other applications are stored in SE2.
C) the logical data size of application program is compared with the first given threshold, if less than the first given threshold,
Then the logical data of application program is stored in SE1, if it is greater than or equal to the second given threshold, then by the logical number of application program
According to being stored in SE2.
Specifically, above-mentioned first given threshold can be set using static mode, can also be set using dynamical fashion.
1) static mode.
The available space of usual SE1 (e.g., the SE of NFC-SIM card) is probably 300Kb, and logical data commonly has
The size of 40Kb), therefore, a fixed threshold value, e.g., 20Kb can be rule of thumb set by administrative staff.
2) dynamical fashion.
The threshold value of one dynamic change is set based on main card total capacity and main card residual capacity, wherein the value of threshold value and " master
The ratio of card total capacity and the first setup parameter " is positively correlated, and the ratio with " main card residual capacity and the second setup parameter " is in
It is positively correlated, and is positively correlated with third setup parameter.
For example, its threshold value generates formula are as follows:
Max (Min ((SE1 total capacity/a), (SE1 residual capacity/b)), c), wherein a is the first parameter preset, b the
Two parameter presets, c are third parameter preset, and optionally, the value range of a is [5,15], and the value range of b is [2,4], c's
Value range is [15Kb, 25Kb]
By above-mentioned formula as can be seen that since SE1 residual capacity/b value can be with application program number of downloads
Increase and dynamic change, therefore, size comparison between (SE1 total capacity/a), (SE1 residual capacity/b) and c also can be with
Variation, therefore, using above-mentioned formula be arranged the first given threshold, value can with the increase of application program download and
It gradually reduces, so as to the more reasonable space planning SE.
Further, during stating the first preset condition in use, if include in ground preset condition at least two
Rule clashes, then according to the priority of each rule setting of correspondence, executes in above-mentioned at least two rules priority most
High rule；Alternatively, above-mentioned at least two rules are notified user, indicated to execute corresponding rule according to user.
Step 410: in application program use process, terminal uses shape according to the setting each application program of cycle detection
Condition combines the second preset condition according to testing result, is adjusted to the storage location of the logical data of certain applications program.
Specifically, the second preset condition has included at least any one in following rule or has appointed in the embodiment of the present invention
Meaning combination:
A) according to the service condition of each application program, setting duration (e.g., monthly, weekly etc.) frequency of usage is filtered out
Highest N number of application program, N are parameter preset.Then, the logical data of above-mentioned N number of application program is stored in main SE,
He is stored in vice card the logical data of application program.
Since the application program use habit of user changes over time and change, terminal needs will periodically make
Entered in SE1 with the logical data unloading for providing high application program frequently, by the logical data unloading of the low application program of frequency of usage
Enter in SE2.
Certainly, unloading is that the application program of the second preset condition is not met for current storage location, if frequency of usage
High application program currently in SE1, then keeps storage location.
B) if the logical data of application program is shareable data, the logical data of application program is stored in main SE
In, so-called main SE is the element for carrying NFC function, such as NFC-SIM card
In practical application, certain logical datas can share a few set personal datas, to be packaged into different application journeys
Sequence, therefore, it is necessary to can deposit in SE1 for needing logical data to be sharing.
C) if the application program for specified type is provided with following rule: the application program of same type in the same time
An application program is allowed to be activated；The application logic data being activated in the specified type are then stored in main SE
In, the logical data of other applications in the specified type is stored in secondary SE.
Specifically, in the embodiment of the present invention distributed storage can also be carried out according to Application Type.Optionally, portion
The application program of classifying type only allows to have within the same time application program to be activated (example in the application program of same type
Such as, financial class application program can only activate an application program simultaneously), therefore, it can will be swashed in the application program of this type
Application program living is stored in SE1, and other applications are stored in SE2.
D) the logical data size of application program is compared with the first given threshold, if less than the first given threshold,
Then the logical data of application program is stored in main SE, if it is greater than or equal to the second given threshold, then by the logic of application program
Data are stored in secondary SE.
