An embodiment of the present application provides an access method for a storage circuit. The storage circuit in the embodiment of the present application refers to a secure element, and the secure element is, for example, an eSE (embedded Secure Element, embedded secure element). eSE can store user data of various types of security applications. The security application may be a bank card application, an identity card application, a bus card application, an access control card application, a phone card application, and the like. Correspondingly, the user data may be various types of bank card information, identity card information, bus card information, access control card information, mobile phone information, and the like. Based on the user data stored in the storage circuit, the computer device can realize the required functions such as payment and authentication by means of NFC.

FIG. 1 is a schematic diagram of an application environment of an access method for a storage circuit according to an embodiment. Referring to FIG. 1 , the application environment includes a storage circuit 100 , a token management module 300 and a plurality of access modules 200 , two of which are shown in FIG. 1 . Access module 200. The aforementioned various bank card applications, identity card applications, bus card applications, access control card applications, phone card applications, etc. may respectively correspond to different access modules 200 . Exemplarily, an access module 200 in an application scenario may be an AP (application process, application processor). It can be understood as an application processing module. Another access module 200 may be a Modem (modem), and the Modem is used to implement the communication function of the calling card application, therefore, the Modem may be understood as a communication module. Optionally, the storage circuit may be configured to include multiple storage areas, and different storage areas store different applications and data respectively. When different access modules 200 access the storage circuit, the corresponding target storage area may be determined according to the requirement information, so as to access the target storage area, thereby improving the efficiency of access.

The access module 200 may be connected to the storage circuit 100 through an interface. The interface types of different types of access modules 200 may be the same or different, which is not limited in this embodiment. Affected by the industry accessing user data, user data of different industry types can be accessed through different industry interfaces. Exemplarily, when electronic ID information such as a bank card needs to be read from the storage circuit 100, it needs to be accessed through a serial peripheral interface (Serial Peripheral Interface, SPI). When the embedded SIM card (Embedded-SIM, eSIM) information needs to be read from the storage circuit 100, it needs to be accessed through the ISO7816 interface defined by GSMA. The embedded SIM card refers to the SIM card formed by moving the information in the traditional physical SIM card to the eSE for storage. Therefore, in the related art, there are situations in which multiple interfaces access the eSE. When different interfaces access the eSE at the same time, a problem of access conflict may be caused. In this embodiment of the present application, the access module 200 may access the storage circuit in response to a demand instruction of the relevant module, so as to obtain the stored user data. Exemplarily, the related module may be a touch control module in a computer device, and the touch control module may generate a demand instruction in response to a user's touch operation, and the demand instruction carries demand information corresponding to the touch operation. Optionally, the demand information includes information such as access type and access content requested for access. The access type refers to the storage type accessed, for example, it can include application management and data read and write. The access content refers to the specific content when accessing a certain storage type, for example, including the specific management type of the application and the specific content of data reading and writing. The specific management type of the application is, for example, application services such as downloading, updating, deleting, querying, authentication, and payment of the application. Therefore, if the demand information is to query the transaction records of the bank card on a certain date, the corresponding access type is bank card information reading, and the access content can be the transaction records of the bank card on that date.

Optionally, the storage circuit 100, the multiple access modules 200 and the token management module 300 are all set in the computer equipment, the storage circuit 100 is respectively connected to the multiple access modules 200, and the token management module 300 is also connected to the multiple access modules 200 respectively. Module 200 is connected. Further, the token management module 300 may be integrated into different access modules 200 as shown in FIG. 2 or FIG. 3 , or may be disposed outside all the access modules 200 as shown in FIG. 1 , which is not limited in this embodiment. Among them, the computer equipment can be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, IoT devices and portable wearable devices, and the IoT devices can be smart speakers, smart TVs, smart air conditioners, smart vehicle-mounted devices, etc. . The portable wearable device may be a smart watch, a smart bracelet, a head-mounted device, or the like.

FIG. 4 is one of the flow charts of a method for accessing a storage circuit according to an embodiment. The method for accessing a storage circuit in this embodiment is applied to the aforementioned token management module. Referring to FIG. 4 , in one embodiment, the access method of the storage circuit includes steps 402 to 406 .

Step 402: Receive a token application request sent by the first access module.

Among them, the token can be understood as the secret code when the access module accesses the storage circuit. That is, an access module with a valid token can access the storage circuit, while an access module with an invalid token or no token cannot access the storage circuit. Therefore, before accessing the storage circuit, the first access module needs to request a token from the token management module through a token application request. After obtaining the token authorized by the token management module, the first access module can access the storage circuit according to the token. Optionally, the token application request may carry demand information including access type and access content, so that the token management module can evaluate whether to authorize the token to the first access module according to the demand information when needed.

Step 404, acquiring the occupation status of the token in response to the token application request.

The occupied state of the token corresponds to the current accessed state of the storage circuit. Specifically, if the occupied state of the token is occupied, it means that other access modules are currently occupying the token and accessing the storage circuit. If the occupied state of the token is not occupied, it means that no access module is currently accessing the storage circuit. It can be understood that, if the first access module forcibly accesses the storage circuit when the storage circuit is being accessed by other access modules, a problem of access conflict will be caused. Therefore, by first querying the occupancy status of the token to determine whether the storage circuit is being accessed, and then performing a corresponding operation according to the query result, repeated authorization of the token can be avoided, thereby avoiding the problem of access conflict.

Step 406, when the occupied state is not occupied, authorize the token to the first access module to instruct the first access module to access the storage circuit through the token.

In this embodiment, by querying the occupation status of the token, it is determined whether the storage circuit is being accessed, and when the token is not occupied, that is, when the storage circuit is not occupied, the authorization token is given to the token application request. The corresponding first access module. Therefore, when multiple access modules access the storage circuit at the same time, the problem of access conflict can be avoided, thereby improving the access reliability of the storage circuit.

In one embodiment, when the occupancy status of the token is currently occupied by the second access module, the token management module may choose to directly suspend the current access of the second access module to the storage module, and authorize the token to the first access module module. The token management module may also choose to further evaluate whether to authorize the token to the first access module according to the requirement information of the first access module and the second access module. The user can set preset rules according to actual needs, and when the occupancy state is occupied, tokens are allocated according to the preset rules, which is not limited in this embodiment.

In one embodiment, if the token management module temporarily does not authorize the token to the first access module because the token is already occupied, the access method of the storage circuit further includes: when the occupied state is currently being accessed by the second access module When occupied, the waiting instruction is returned to the first access module to instruct the first access module to send the token application request again after the first time period. It can be understood that when the first access module requests to access the storage circuit, the storage circuit may be in an idle state, that is, there is currently no second access module holding the token and accessing the storage circuit, and the storage circuit may also be in an idle state. Access the state of module access. Moreover, the access modules specifically referred to by the first access module and the second access module may vary over time. For example, in the first time period, if the bank card application requests to obtain bank card information, the first access module in the first time period refers to the AP for executing the bank card application. In the second period, if the eSIM requests to obtain eSIM information, the first access module in the second period refers to the Modem used to implement the communication function of the eSIM. Correspondingly, the same access module can also be used as the first access module in the first time period and as the second access module in the second time period, and can also be used as neither the first access module nor the second access module in the third time period. Access modules.

Wherein, in a possible embodiment, the first duration may be information configured in the first access module, and the first duration may be set according to the urgency of the service processed by the first access module. That is, the token management module only needs to return the waiting instruction every time, without informing the first access module of the required waiting time. After receiving the waiting instruction, the first access module can send the token application request again after waiting for the preconfigured first duration. In another possible embodiment, the first duration may be information carried by the waiting instruction. That is, the token management module can automatically select an appropriate first duration, and when sending the waiting instruction, synchronously inform the first access module of the duration to wait. After receiving the waiting instruction, the first access module parses the waiting instruction to obtain the first duration of waiting, and can send the token application request again after the first duration.

In this embodiment, by setting an appropriate first duration, it is possible to prevent the first access module from sending token application requests too frequently, thereby avoiding waste of resources on the signal bus. At the same time, it can also be avoided that the first access module cannot obtain the token for a long time, resulting in a delay in the access of the first access module to the storage circuit. Therefore, based on the access method of this embodiment, the first access module can send a token application request at a relatively reasonable frequency, and can access the storage circuit in a timely manner to read user data stored in the storage circuit.

In one embodiment, the token management module is further configured to count the number of times the token application request is received within the second time period, and perform corresponding operations according to the number of times. Wherein, the second duration is longer than the first duration. The first duration may be, for example, 0.05s, 0.1s, or 1s, and the second duration may be, for example, 0.5s, 0.8s, or 3s, which is not limited in this embodiment. That is, if the number of token application requests received in the second time period is less than the preset number, it means that the access urgency of the first access module is low, and the token can be authorized to the first access module after the second access module completes the access. An access module. If the number of token application requests received within the second time period is greater than or equal to the preset number of times, it indicates that the access urgency of the first access module is relatively high, and a comprehensive evaluation of the access conditions of the first access module and the second access module is required. , to determine whether to authorize the token to the first access module. The preset number of times may be positively correlated with the second duration and negatively correlated with the first duration. That is, on the premise that the second duration is unchanged, the shorter the first duration, the larger the preset number of times can be set correspondingly; the longer the first duration, the smaller the preset number of times can be set correspondingly. Therefore, the corresponding preset number of times may be specifically set according to the ratio between the second duration and the first duration.

The number of times the token application request is received within the second time period may refer to the number of times the token application request sent by the same first access module is received within the second time period. For example, if two access modules in the computer device need to access the storage circuit at the same time, and respectively send token application requests to the token management module, the two access modules can simultaneously serve as the first access module. However, the token management module needs to separately count the number of times that each first access module sends a token application request. Therefore, the statistical results can be as follows, for example, the first access module A sends two token application requests within the second time period, and the first access module B sends four token application requests within the second time period. Based on the above statistical results, the first access module B needs to be given priority to authorize the token.

Further, the number of times the token application requests are received within the second time period may also refer to the number of times the token application requests sent by the same first access module for executing the same service are received within the second time period. If the same first access module sends token application requests to the token management module in order to execute different services, the token management module needs to count the times corresponding to each service respectively. For example, if the AP sends a token application request to the token management module once for executing the bank card application, and sends three token application requests to the token management module for executing the bus card application. The token management module needs to separately count the number of times of request sending corresponding to each service. Therefore, the statistical results may be as follows, for example, the AP sends a token application request within the second period of time to execute the bank card application, and the AP sends three token application requests within the second period of time for the execution of the bus card application. Based on the above statistical results, it is necessary to give priority to the authorization token to the AP to execute the bus card application.

FIG. 5 is the second flow chart of a method for accessing a storage circuit according to an embodiment. Referring to FIG. 5 , in one embodiment, based on the statistical result of the number of times of token application requests, the method for accessing a storage circuit includes steps 502 to 502 Step 510. It should be noted that this embodiment focuses on the implementation when the occupied state is currently occupied by the second access module, so step 406 in the implementation when the occupied state is not occupied in the previous embodiment is not specifically shown. Moreover, steps 502 to 506 in this embodiment have been described in the foregoing embodiments, and reference may be made to the foregoing embodiments, and details are not repeated here.

Step 502: Receive a token application request sent by the first access module.

Step 504, acquiring the occupation status of the token in response to the token application request.

Step 506 , when the occupied state is currently occupied by the second access module, return a waiting instruction to the first access module to instruct the first access module to send the token application request again after the first time period.

Step 508 , if the number of token application requests received within the second time period is greater than the preset number of times, an interrupt instruction is sent to the second access module to instruct the second access module to interrupt the access to the storage circuit.

Step 510: Reclaim the token of the second access module, and authorize the token to the first access module.

In a possible embodiment, for the specific implementation of the step of recycling the token of the second access module, the second access module may take the initiative to return the token to the Token management module. In another possible embodiment, after sending the interrupt instruction, the token management module may actively cancel the access authority of the token held by the second access module, that is, the token management module makes the access rights of the token held by the second access module The token held is invalid. Wherein, before the token management module actively cancels the access authority, it can also wait for a third period of time to ensure that the second access module has interrupted the access to the storage circuit.

In this embodiment, the token management module sends the interrupt instruction first, and then recycles the token of the second access module, so as to prevent the access authority of the second access module from being suddenly cancelled, thereby avoiding the occurrence of the access process of the second access module error, thereby improving the accuracy of data reading by the second access module.

In one of the embodiments, the second access module receives the interrupt instruction, and when the access to the storage circuit is interrupted, the location where the access is interrupted, that is, the interrupt breakpoint can be stored. By setting the interruption breakpoint, it is convenient for the second access module to directly search for the interruption point and continue to access from the interruption point, thereby improving the speed of the second access module to resume access. Therefore, after the token is recovered from the second access module through the interrupt instruction, the access method of the storage circuit further includes: when the first access module releases the token, authorizing the token to the interrupted second access module to indicate the second access module. The access module continues to access the storage circuit from the interruption breakpoint, and the interruption breakpoint is the position where the second access module interrupts the access in response to the interruption instruction. The interrupt breakpoint can be stored in the second access module, and after the second access module re-acquires the token, it can first read the stored interrupt breakpoint from the inside, and continue to access the storage circuit according to the interrupt breakpoint, so as to Get some data that was not read before the interruption. It can be understood that, in some embodiments, in order to achieve the integrity and continuity of read data, all data may also be re-acquired when re-accessing the storage circuit, which is not limited in this embodiment.

FIG. 6 is a third flowchart of a method for accessing a storage circuit according to an embodiment. Referring to FIG. 6 , in one embodiment, the method for accessing a storage circuit includes steps 602 to 614 . That is, in this embodiment, before the token management module sends the interrupt instruction to the second access module, it further includes: sending an inquiry instruction to the second access module to instruct the second access module to determine whether to agree to release according to the current access state information token, and the consent release instruction returned by the second access module is received. It should be noted that, steps 602 to 606 and steps 612 to 614 in this embodiment have been described in the foregoing embodiments, and reference may be made to the foregoing embodiments, which will not be repeated here.

Step 602: Receive a token application request sent by the first access module.

Step 604, obtaining the occupation status of the token in response to the token application request.

Step 606, when the occupancy state is currently occupied by the second access module, return a waiting instruction to the first access module to instruct the first access module to send the token application request again after the first time period.

Step 608: If the number of token application requests received in the second time period is greater than the preset number, send an inquiry instruction to the second access module to instruct the second access module to determine whether to agree to release the token according to the current access state information.

Wherein, the access state information includes at least one of urgency, remaining access duration and remaining access data volume. The degree of urgency may include, for example, very urgent, relatively urgent, and general urgency. The remaining access duration may be, for example, 0.3s, 0.4s, or the like. The remaining access data amount may be, for example, 200kb, 1M, or the like. Algorithm rules may be preconfigured in the second access module, and the second access module may acquire the current access status information when receiving the query instruction, and, according to the acquired access status information and the preconfigured algorithm rules, analyze the current access status information. The access situation is comprehensively evaluated to determine whether to agree to release the token. Further, the token management module can also send information such as the urgency of the first access module, the estimated access duration, and the estimated access data volume to the second access module, so that the second access module can make a more accurate evaluation.

Step 610 , when receiving the approval release instruction returned by the second access module, send an interrupt instruction to the second access module to instruct the second access module to interrupt the access to the storage circuit.

Step 612: Reclaim the token of the second access module, and authorize the token to the first access module.

Step 614, when the first access module releases the token, authorize the token to the interrupted second access module, so as to instruct the second access module to continue accessing the memory circuit from the interruption point.

In this embodiment, by sending an inquiry instruction, the access process of the second access module can be not interrupted when the remaining access duration of the second access module is short or the urgency is high, so that the second access module is complete to complete the current access, thereby increasing the flexibility of the access method.

In some of these embodiments, when the second access module requests a token, it can directly send information such as the urgency, estimated access duration, and estimated access data volume to the token management module, and the token management module can directly respond to the The access situation of the interrupted second access module is evaluated without sending an inquiry instruction to the second access module, which improves the evaluation speed. It is understandable that, compared with the actual remaining access duration and remaining access data volume, the accuracy of the estimated access duration and the estimated access data volume is slightly worse, and accordingly, very accurate evaluation results cannot be provided. Therefore, in a scenario that requires relatively low accuracy, the solution of this embodiment can be used to improve the interaction speed.

In one of the embodiments, after sending the inquiry instruction to the second access module, the access method for the storage circuit further includes: when receiving the refusal and release instruction returned by the second access module, sending a pause request instruction to the first access module to Instruct the first access module to suspend sending the token application request. Specifically, the second access module may send a refusal to release the instruction when the urgency is high or the remaining access duration is short. It can be understood that if the current evaluation result of the second access module is refusal to release the token, the second access module will not change the evaluation result to agree to release the token for the same query instruction before the second access module completes the current access task. Therefore, even if the first access module continues to send the token application request, the second access module will not release the token. In this embodiment, the above-mentioned setting manner can avoid the waste of bus resources caused by the continuous sending of requests by the first access module, thereby improving the running speed of the computer device.

But it can be understood that if the first access module generates a new token application request in response to the new service, it can send the new token application request to the token management module, so as to avoid affecting the operation of the new service. Further, the first access module can also perform an internal evaluation first, and if the information such as the urgency of the new service is lower than that of the old service, the token application request may not be sent first, thereby avoiding waste of resources.

FIG. 7 is a fourth flowchart of an access method for a storage circuit in an embodiment. The access method in this embodiment is applied to the second access module. Referring to FIG. 7 , in one embodiment, the access method for a storage circuit includes step 702 Go to step 706 .

Step 702: Receive an interrupt instruction sent by the token management module. The interrupt instruction is an instruction generated when the token management module receives the token application request sent by the first access module more than a preset number of times within the second time period.

Step 704, interrupting the access to the storage circuit in response to the interrupt instruction, and generating an interrupt breakpoint at the location where the access is interrupted.

Step 706: Release the token to the token management module to instruct the first access module and the second access module to access the storage circuit by time-sharing through the token. Wherein, the token management module is used to authorize the token to the first access module and the second access module.

In this embodiment, the second access module releases the token in response to the interrupt instruction, so that the access authority of the second access module can be prevented from being suddenly cancelled, so that errors in the access process of the second access module can be avoided, and the second access module can be improved. The accuracy of the module's data reading. Moreover, by setting the interruption breakpoint, it is convenient for the second access module to directly search for the interruption point and continue to access from the interruption point, thereby improving the speed of the second access module to resume access.

In one of the embodiments, before receiving the interrupt instruction sent by the token management module, the method for accessing the storage circuit further includes the following steps. The second access module receives the query instruction sent by the token management module. The second access module acquires current access state information in response to the query instruction, where the access state information includes at least one of an emergency degree, a remaining access duration and a remaining access data amount. The second access module determines, according to the access state information, whether to agree to release the token, and correspondingly returns one of an approval release instruction and a refusal release instruction to the token management module. In this embodiment, the second access module, by receiving the inquiry instruction, can send an approval release instruction when the remaining access time is long or the urgency is low, so that the first access module first accesses the storage circuit. The second access module can also send a refusal and release instruction when the remaining access duration is short or the urgency is high, so as to avoid interrupting the access process of the second access module, so that the second access module can completely complete the current access, thereby increasing the flexibility of the access method.

It should be understood that, although the steps in the flowcharts are displayed in sequence according to the arrows, these steps are not necessarily executed in the sequence indicated by the arrows. Unless explicitly stated herein, the execution of these steps is not strictly limited to the order, and these steps may be performed in other orders.
