[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0028] It is understood that the terms "first," "second," etc., used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, without departing from the scope of this application, a first client may be referred to as a second client, and similarly, a second client may be referred to as a first client. Both the first client and the second client are clients, but they are not the same client.

[0029] Figure 1 This is a schematic diagram illustrating the application environment of a storage circuit access method in one embodiment. For example... Figure 1 As shown, the application environment includes a storage circuit 100, a first access module 200, and a second access module 300. The first access module 200 and the second access module 300 are respectively connected to the storage circuit 100, and the execution entity of the access method can be either the first access module 100 or the second access module 200.

[0030] The storage circuit 100 can store various applications and data for access by the first access module 200 and the second access module 300. The storage circuit can be a secure element, such as an eSE. The eSE can store various types of security applications and user personal data. Security applications can include various bank cards, ID cards, public transport cards, access control cards, phone cards, etc., while user personal data can include various bank card information, ID card information, public transport card information, access control card information, mobile phone information, etc.

[0031] The first access module 200 is connected to the second access module 300 via the connection unit 400. When the first access module 200 and the second access module 300 need to access the storage circuit 100, both the first access module 200 and the second access module 300 determine whether to perform an access operation based on the voltage level of the connection unit 400. Specifically, the first access module 200 and the second access module 300 determine that an access operation can be performed when the voltage level of the connection unit 400 is detected to be at the first voltage level. The number of the first access module 200 and the second access module 300 can be one or more.

[0032] The connection unit 400 is a bidirectional controlled unit, controlled by both the first access module 200 and the second access module 300. Under the control of the first access module 200 and the second access module 300, the connection unit 400 can change its voltage level.

[0033] Optionally, the connection unit 400 can be a bidirectional controlled pin, such as a bidirectional controlled pin (e.g. Figure 2 As shown in Figure 400A (this is just an example and not a limitation), one side of the bidirectional controlled pin is connected to the first access module 200, and the other side is connected to the second access module 300. The operating state and level state of the side of the bidirectional controlled pin connected to the first access module 200 are controlled by the first access module 200, and the operating state and level state of the other side of the bidirectional controlled pin connected to the second access module 300 are controlled by the second access module 300.

[0034] In other embodiments, the connection unit 400 may also be a bidirectional controlled comparison unit or processing unit, and can switch level states under the control of the first access module 200 and the second access module 300. For example, if the connection unit 400 is a bidirectional controlled comparison unit, then when the connection unit 400 is configured as an input state, it can be directly configured with level signals by the first access module 200 and the second access module 300; when configured as an output state, it can switch level states according to preset signals output by the first access module 200 and the second access module 300.

[0035] Optionally, the first access module 200 can be an AP (Application Processor) for executing applications, etc., and can be understood as an application processing module; the second access module 300 can be a Modem (Modem Controller) for implementing communication functions, and can be understood as a communication module. It is understood that the first access module 200 can also be a Modem, and the second access module 300 can also be an AP. Specifically, when the first access module 200 is an AP and the second access module 300 is a Modem, the first access module 200 can be connected to the storage circuit via an SPI interface, and the second access module 300 can be connected to the storage circuit 100 via an ISO interface.

[0036] Optionally, when the first access module 200 accesses the storage circuit 100 as an AP, it can access electronic cards such as bus cards, bank cards, access control cards, and eIDs, along with their related data, through the wallet service program (Wallet_Service). When the second access module 300 accesses the storage circuit 100 as a Modem, it can implement related application services such as eSIM creation, deletion, and authentication within the storage circuit 100 through the communication service program (eSIM_Service).

[0037] Optionally, the first access module 200, the second access module 300, and the connection unit 400 are disposed in a terminal device. The terminal device may be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices may include smart speakers, smart TVs, smart air conditioners, smart in-vehicle devices, etc. Portable wearable devices may include smartwatches, smart bracelets, head-mounted devices, etc. Optionally, the storage circuit 100 may be disposed in the same terminal device as the first access module 200, the second access module 300, and the connection unit 400, or it may be disposed in another terminal device.

[0038] Figure 2 This is a flowchart of a memory circuit access method in one embodiment. The access method in this embodiment is designed to operate on... Figure 1 Let's take the first access module in the example as an example. Figure 2 As shown, the access method includes steps 202 to 204.

[0039] Step 202: Upon receiving the first request information requesting access to the storage circuit, obtain the level state of the connection unit.

[0040] The first request information refers to the information sent by the relevant module to the first access module requesting access to the storage circuit, instructing the first access module to access the storage circuit and provide corresponding access information. Optionally, the relevant module generates corresponding first request information based on the user's access needs and sends it to the first access module. The relevant module may be, for example, the touch module of the terminal device, where the user inputs relevant request commands to the touch module, causing the touchscreen to generate the first request information accordingly.

[0041] Optionally, the first request information includes information such as the access type and access content. The access type refers to the storage type being accessed, which may include application management and data read / write. The access content refers to the specific content accessed when accessing a particular storage type, including the specific management type of the application and the specific content of data read / write. The specific management type of the application may be, for example, application services such as downloading, updating, deleting, querying, authenticating, and paying. For example, if the first request information is to query the transaction records of a certain bank card in October 2021, then the corresponding access type is bank card information reading, and the access content could be the transaction records of the certain bank card in October 2021.

[0042] The voltage level of the connection unit can include at least two different voltage levels, such as a first voltage level and a second voltage level, where the first voltage level and the second voltage level are different. For example, the first voltage level may be low and the second voltage level may be high; or the second voltage level may be low and the first voltage level may be high. It is understood that the first voltage level and the second voltage level can also be other voltage levels, as long as they are different.

[0043] Optionally, the voltage level of the connection unit can be obtained by the first access module in binary form. Taking the first voltage level as low and the second voltage level as high as an example, the first low voltage level can be configured to be obtained by the first access module in binary form as "0" and the second low voltage level as binary "1", and the voltage level of the connection unit can be determined by the binary digital form.

[0044] Step 204: When the level state is the first level state, perform an access operation. The access operation includes controlling the level state of the connection unit to the second level state and accessing the storage circuit.

[0045] Both the first and second access modules are configured to perform an access operation when they need to access the storage circuit and determine that the connection unit is in a first-level state. Performing the access operation includes controlling the first-level state to a second-level state while simultaneously accessing the storage circuit. Therefore, in step 204, when the first access module detects that the level state is the first-level state, it can determine that the second access module is not accessing the storage circuit or is in a state of stopping access to the storage circuit, thereby further determining that the storage circuit is not occupied. At this time, the first access module updates the level state of the connection unit and accesses the storage circuit, which not only enables access to the storage circuit but also alerts other access modules that are currently in the access phase, avoiding access conflicts caused by other access modules accessing the storage circuit simultaneously.

[0046] The control of the level state of the connection unit can be achieved by configuring the connection unit's operating state as an input state, allowing direct configuration of the connection unit's level state when it is in an input state; alternatively, it can be configured as an output state, changing the connection unit's level state by outputting a preset signal. Therefore, by first configuring the connection unit's operating state and then further configuring its level state or outputting a preset signal, the connection unit's level state can be updated from a first level state to a second level state.

[0047] Accessing the storage circuit refers to managing applications within the storage circuit and reading / writing the stored data. The first access module manages applications within the storage circuit, including downloading, updating, deleting, querying, authenticating, and making payments. When managing applications, it can query the configuration files of relevant applications in the storage circuit and launch related application services based on the configuration files. The first access module also reads and writes the data stored in the storage circuit, including reading and storing data. For example, if the first request is to query bank card transaction records, then during access, bank card transaction records can be queried from the data list in the storage circuit.

[0048] Optionally, the storage circuit can be configured to include multiple storage areas, each corresponding to different applications and data. When accessing the storage circuit, the target storage area can be determined based on the first request information, so as to perform the corresponding access in the target storage area.

[0049] Optionally, the storage circuit can be configured to include a first storage area accessible only to a first access module and a second storage area accessible only to a second access module, thereby improving the security of the storage circuit. When accessing the storage circuit, the corresponding access can be performed in the first storage area according to the first request information, thereby improving the efficiency of access.

[0050] The access method provided in this embodiment is applied to a first access module, which is connected to a second access module via a connection unit. The first and second access modules perform an access operation when the voltage level of the connection unit is detected to be a first voltage level. The access method obtains the voltage level of the connection unit upon receiving a first request to access the storage circuit; when the voltage level is the first voltage level, it performs an access operation, which includes controlling the voltage level of the connection unit to a second voltage level and accessing the storage circuit; wherein the second voltage level is different from the first voltage level. This avoids the access conflict that may occur when multiple access modules access the storage circuit when it is already occupied.

[0051] In some embodiments, such as Figure 3 As shown, step 204 includes:

[0052] Step 302: When the level state is the first level state, configure the working state of the connection unit to the output state and output a preset signal to the connection unit so that the level state of the connection unit is updated to the second level state and the storage circuit is accessed.

[0053] When the connection unit is configured as an output state by the first access module, it can serve as the output terminal of the first access module, receiving a preset signal output by the internal circuit of the first access module and changing its level state under the influence of the preset signal. It is understood that in other embodiments, when the connection unit is configured as an output state by the second access module, it can serve as the output terminal of the second access module, receiving a preset signal output by the internal circuit of the second access module and changing its level state under the influence of the preset signal.

[0054] The preset signal refers to a signal capable of changing the voltage level of the connection unit. Specifically, the preset signal can switch the operating state of the connection unit from a first voltage level to a second voltage level. The preset signal is set according to the configuration of the first and second voltage levels and the specific type of the connection unit. For example, if the first voltage level is configured as low, the second voltage level as high, and the connection unit is a bidirectional controlled pin, then the preset signal can be a high-level signal output by the first access module, thereby causing the bidirectional controlled pin to switch its voltage level from low to high. It is understood that in other embodiments, if the connection unit is another unit with instruction receiving and processing functions, the preset signal can also be a switching instruction, causing the connection unit to switch its voltage level according to the switching instruction.

[0055] This embodiment updates the level state of the connection unit by configuring the connection unit to an output state and outputting a preset signal to the connection unit, which simplifies the level state control process and improves access efficiency.

[0056] In some embodiments, such as Figure 3 As shown, the access methods also include:

[0057] Step 304: If a preset signal is received from the second access module to the connection unit at the same time as the preset signal is output to the connection unit, the second request information of the second access module to access the storage circuit is obtained.

[0058] The connection unit is a bidirectional controlled unit. The operating state of the side of the connection unit connected to the first access module is controlled by the first access module, and the operating state of the other side of the connection unit connected to the second access module is controlled by the second access module. Therefore, it is possible that both the first and second access modules simultaneously detect that the voltage level of the connection unit is at the first voltage level and simultaneously perform related operations on both sides of the connection unit to access the storage circuit. In this case, when the first access module configures the operating state of one side of the connection unit to the output state and outputs a preset signal, the second access module may also simultaneously configure the operating state of the other side of the connection unit to the output state and output a preset signal. At this time, the first access module can obtain the second request information from the second access module, so as to determine whether to continue access in subsequent steps according to the access priority of the first and second access modules.

[0059] The second request information refers to the information sent by the relevant module to the second access module requesting access to the storage circuit, instructing the second access module to access the storage circuit and provide corresponding access information. Optionally, the relevant module generates corresponding second request information based on the user's access needs and sends it to the second access module. The relevant module may be, for example, the touch module of the terminal device, where the user inputs relevant request instructions to cause the touchscreen to generate the second request information accordingly. Optionally, the second request information includes information such as the access type and access content requested. For details on access type and access content, please refer to the relevant descriptions in the above embodiments, which will not be repeated here.

[0060] Optionally, the first access module and the second access module can access each other to obtain the requested information. For example, an information transmission channel can be set up between the first and second access modules, allowing them to access each other's requested information. This information transmission channel can be a temporary logical channel, for example, it can be set to be established within a preset time period to establish a communication connection between the first and second access modules, such as only during the time period when the first access module needs to request access, or during the time period after the terminal device is powered on. It is understood that the information transmission channel can also be a permanent logical channel, coexisting with the first and second access modules to permanently establish a communication connection between them. By directly querying the second access module to obtain the second requested information, the first access module can reduce time costs, improve access efficiency, and further enhance the user experience.

[0061] Step 306: Determine the priority information in the first request information and the second request information based on the first request information and the second request information.

[0062] The priority information can be request information with higher importance or urgency. After obtaining the second request information, the first and second request information are compared to obtain their priority information. The mechanism for determining importance and urgency can be preset. Optionally, all possible request information can be classified into levels based on the application of the storage circuit and the importance of the data, thereby determining the first request information and its priority information based on the classification. Optionally, a priority list can be preset, and the priority information of the first and second request information can be determined based on their ranking in the priority list.

[0063] For example, the first request is for paying with a bus card, and the second request is for updating the bus card's transaction records at 9:00 PM every day. If the two requests are received by the first access module and the second access module at 9:00 PM respectively, then the first access module and the second access module need to access the storage circuit simultaneously. Relative to the user, the first request for paying with a bus card can be considered a request with a higher degree of urgency, so the first request can be determined as priority information.

[0064] Step 308: When the first request information is priority information, continue to output a preset signal to the connection unit and access the storage circuit.

[0065] When the first request information is priority information, the first access module continues to initiate the relevant steps for accessing the memory circuit. Simultaneously, the second access module can actively or passively learn that the first access module is in an access state. For example, the second access module also executes steps 304-308, thus also determining that the first request information is priority information and maintaining the current request state. For example, simultaneously with step 308, the first access module can send relevant indication information indicating that the first request information is priority information to the second access module, instructing the second access module to maintain the current request state.

[0066] By determining the priority information and initiating the relevant operations to access the storage circuit when the first request information is determined to be the priority information, access conflicts that may occur when multiple modules access the storage circuit at the same time can be avoided.

[0067] In some embodiments, such as Figure 3 As shown, the access methods also include:

[0068] Step 310: When the second request information is priority information, stop the output of the preset signal and reacquire the level state of the connection unit.

[0069] When the second request information is priority information, the first access module maintains the current request state. While maintaining the current request state, the second access module can also execute steps 304-310. Therefore, the second request information is also determined to be priority information and the relevant operation of accessing the storage circuit is started. At this time, the access conflict that may occur if the first access module and the second access module access the storage circuit at the same time can still be avoided.

[0070] In some embodiments, the first access module and the second access module are respectively connected to a random timing module. When the random timing module receives a random timing instruction, it outputs a first timing instruction to the first access module to instruct the first access module to access the storage circuit at a first random time, and outputs a second timing instruction to the second access module to instruct the second access module to access the storage circuit at a second random time. The first random time and the second random time are different. Figure 4 As shown, the access methods also include:

[0071] Step 312: If a preset signal is received from the second access module at the same time as the preset signal is output to the connection unit, a random timing command is sent to the random timing module.

[0072] When the first access module and the second access module simultaneously detect that the level state of the connection unit is the first level state and simultaneously perform related operations to access the storage circuit on both sides of the connection unit, the first access module can send a random timing instruction to the random timing module to trigger the random timing module to feed back the first timing instruction and the second timing instruction to the first access module and the second access module respectively, so that the first access module and the second access module access the storage circuit at different random times to avoid access conflicts.

[0073] Step 314: Receive the first timing instruction fed back by the random timing module, continue to output a preset signal to the connection unit at the first random time according to the first timing instruction, and access the storage circuit.

[0074] The first timing instruction includes a first random time to initiate access and a first duration of random access; the second timing instruction includes a second random time to initiate access and a second duration of random access. The first and second random times are different, and the first and second durations can be the same or different. Optionally, the time interval between the first and second random times is set to be greater than both the first and second durations. This ensures that the access process does not overlap after access is initiated at different random times, further ensuring that the first and second access modules access the storage circuit at different time periods.

[0075] Therefore, when the first access module receives the first timing instruction from the random timing module, it continues to output a preset signal to the connection unit at a first random moment to change the level state of the connection unit, and simultaneously accesses the storage circuit. This avoids simultaneous access to the storage circuit with the second access module, thus preventing access conflicts.

[0076] In some embodiments, the access method further includes:

[0077] Step 402: When the access to the storage circuit ends, the working state of the connection unit is configured to the input state and the level state of the connection unit is configured to the first level state; wherein, the level state priority in the output state is higher than the level state priority in the input state.

[0078] When the connection unit is configured as an input by the first access module, it can serve as an input terminal of the first access module, and the level state of the connection unit can be directly configured by the first access module. Optionally, when the connection unit is configured as an input, taking a high level as an example, the first access module can directly pull the level state of the connection unit to a high level through an internally set pull-up unit, such as a pull-up resistor; taking a low level as an example, the first access module can directly pull the level state of the connection unit to a low level through an internally set pull-down unit, such as a pull-down resistor.

[0079] More specifically, taking a connection unit as a bidirectional controlled pin, a first level state as low level, and a second level state as high level as an example, when the first access module detects that the level state of the bidirectional controlled pin is low level, it controls the low level to high level and writes or reads data to the storage circuit at the same time. After the data writing or reading is completed, it pulls the level state of the bidirectional controlled pin low.

[0080] It is understood that in other embodiments, when the connection unit is configured as an input state by the second access module, the level state of the connection unit can be directly configured by the second access module as an input terminal of the second access module.

[0081] Specifically, when access to the storage circuit ends, the working state of the connection unit is configured to the input state and the level state of the connection unit is configured to the first level state. This can prompt other access modules that the current access is stopped, so that other access modules can determine that the storage circuit is in an idle state and is not occupied.

[0082] In this case, the level state priority in the output state is higher than that in the input state. Since the connection unit is a bidirectional controlled unit, its working state can be controlled by both the first access module and the second access module at the same time. Therefore, there may be a situation where the first access module and the second access module control the connection unit at the same time. When one side of the connection unit is controlled by the first access module to be in the input state and configured with the first level state, while the other side is controlled by the second access module to be in the output state and outputs a preset signal to make the level state the second level state, since the level state priority in the output state is higher than that in the input state, the connection unit will ultimately present the level state of the output state side, and no configuration conflict will occur.

[0083] The following further explains why the level priority is higher in the output state than in the input state:

[0084] When the connection unit is configured as an input, the level obtained by pulling up or pulling down is relatively weak, only maintaining a stable level. However, in the output state, the driving capability is stronger, and it is easier to control the connection unit to the output state level through preset signals. For example, if the bidirectional controlled pin is configured as a pull-up pin by the AP to change the level state to a high level, but the other side is output as a low level by the Modem, then the pin will eventually present a low level state.

[0085] Optionally, since the priority of the level state is lower in the input state than in the output state, the default configuration of the connection unit can be set to the input state so that the connection unit can be directly switched to the output state when it is necessary to start the relevant operation of accessing the memory circuit.

[0086] In some embodiments, the access method further includes:

[0087] Step 404: When the level state is the second level state, maintain the current request state until the second level state is updated to the first level state.

[0088] Specifically, when the access level is in the second level state, the second access module is accessing the storage circuit, and the storage circuit is occupied. At this time, the first access module maintains its current request state to restrict its own access to the storage circuit. Until the second level state is updated to the first level state, the second access module is in a state of stopping access to the storage circuit, and the storage circuit is no longer occupied. At this point, it can return to step 204 to initiate the relevant operations for accessing the storage circuit. This avoids the access conflict caused by the first and second access modules accessing the storage circuit simultaneously.

[0089] In other embodiments, when the level state is the second level state, no operation may be performed until the second level state is updated to the first level state, and then the relevant operation for accessing the memory circuit may be directly initiated.

[0090] In some embodiments, the first access module is configured with a service program; such as Figure 5 As shown, the access methods also include:

[0091] Step 502: When the level state is the second level state, start the service program so that the service program generates a notification message when it detects that the second level state has been updated to the first level state.

[0092] When the voltage level is in the second voltage level state, the first access module can determine that the storage circuit is occupied, and at this time, it starts the service program. The service program has the function of monitoring the voltage level state and generating corresponding notification information when the voltage level state is updated, so as to quickly notify the first access module to start the relevant operations to access the storage circuit.

[0093] Step 504: Upon receiving the notification information, control the connection unit to the second level state and access the storage circuit.

[0094] Upon receiving a notification message, the first access module can quickly determine that the current storage circuit is not occupied and initiate the relevant steps to access the storage circuit, thereby improving access efficiency and user experience.

[0095] In other embodiments, the above-described service program can be configured to have only monitoring and notification functions, or it can be configured to simultaneously have access functions so that when the second level state is detected to be updated to the first level state, the service program can directly control the level state of the connection unit to the second level state and access the storage circuit.

[0121] The first access module 200 is connected to the storage circuit 100; the second access module 300 is connected to the storage circuit 100; wherein:

[0122] The first access module 200 is connected to the second access module 300 via the connection unit 400; the first access module 200 and the second access module 300 are used to perform an access operation when the level state of the connection unit 400 is detected to be the first level state.

[0123] The first access module 200 is used to obtain the level state of the connection unit 400 when it receives a first request information requesting access to the storage circuit 100; when the level state is the first level state, it performs an access operation, which includes controlling the level state of the connection unit 400 to the second level state and accessing the storage circuit 100; the second level state is different from the first level state.

[0124] The storage circuit 100 can be located inside or outside the terminal device 10. Figure 8 Taking the storage circuit 100 as an example where it is located inside the terminal device 10. The relevant descriptions of the storage circuit 100, the first access module 200, the second access module 300, and the connection unit 400 are as described in the above embodiments and will not be repeated here.

[0125] Optionally, the connection unit 400 is a bidirectional controlled pin, which is connected to the first access module 200 and the second access module 300 respectively. For a description of the bidirectional controlled pin, please refer to the relevant descriptions in the above embodiments, and they will not be repeated here.

[0126] The following example uses the first access module 200 as the access point (AP), the second access module 300 as the modem, and the connection unit 400 as a bidirectional controlled pin with the first level being high and the second level being low. Figure 10 Further explanation from the examples:

[0127] When the AP needs to access eSE, it detects the level of the pin. When the pin is high, it configures the pin as an output and outputs a low level while accessing eSE. After accessing eSE, it configures the pin as an input and pulls it up internally.

[0128] When the AP needs to access the eSE, it detects the level state of the pin. When the pin state is low, the pin is pulled low by the Modem side. At this time, the Modem is accessing the eSE, and the AP waits until it detects that the pin level state has been updated to high.

[0129] In the terminal device provided in this embodiment, a first access module 200 is connected to a second access module 300 via a connection unit 400. The first access module 200 and the second access module 300 are used to perform an access operation when the voltage level of the connection unit 400 is detected to be a first voltage level. The first access module 200 obtains the voltage level of the connection unit 400 upon receiving a first request to access the storage circuit 100; when the voltage level is the first voltage level, it performs an access operation, which includes controlling the voltage level of the connection unit 400 to a second voltage level and accessing the storage circuit 100; wherein the second voltage level is different from the first voltage level. Therefore, the problem of access conflicts that may occur when multiple access modules access the storage circuit 100 when it is already occupied can be avoided.
