[0053] The exemplary embodiments will be described in detail herein below with reference to the drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0054] It can be understood that, before using the technical solutions disclosed in the embodiments of the present application, the type of personal information involved in the present application, the use range, the use scenario, etc. should be informed to the user and the authorization of the user should be obtained in a proper manner according to relevant laws and regulations.

[0055] For example, in response to receiving an active request of a user, a prompt information is sent to the user to explicitly prompt the user that the operation requested to be performed will need to obtain and use the personal information of the user. Thus, the user can voluntarily choose whether to provide the personal information to the electronic device, the application program, the server or the storage medium, etc. software or hardware performing the operation of the technical solutions of the present application according to the prompt information.

[0056] As an optional but non-limiting implementation, in response to receiving an active request of a user, the manner of sending a prompt information to the user may, for example, be a pop-up window manner, in which the prompt information can be presented in a text manner. In addition, the pop-up window can also carry a selection control for the user to select "agree" or "disagree" to provide the personal information to the electronic device.

[0057] It can be understood that the above notification and obtaining of the authorization of the user are only illustrative and do not limit the implementation of the present application, and other manners meeting the relevant laws and regulations can also be applied to the implementation of the present application.

[0058] For the convenience of understanding, the concepts involved in the embodiments of the present application are described below.

[0059] Electronic device: a device with wireless transceiver function. The electronic device can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted. The electronic device can be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) electronic device, an augmented reality (AR) electronic device, a wireless terminal in industrial control, a vehicle-mounted electronic device, a wireless terminal in self driving, a wireless electronic device in remote medical, a wireless electronic device in smart grid, a wireless electronic device in transportation safety, a wireless electronic device in smart city, a wireless electronic device in smart home, a wearable electronic device, etc. The electronic device involved in the embodiments of the present application can also be referred to as a terminal, a user equipment (UE), an access electronic device, a vehicle-mounted terminal, an industrial control terminal, a UE unit, a UE station, a mobile station, a mobile station, a remote station, a remote electronic device, a mobile device, a UE electronic device, a wireless communication device, a UE agent or a UE apparatus, etc. The electronic device can also be fixed or mobile.

[0060] In the related art, when a user pulls out the card tray in the electronic device, if the power-off time of the card tray is slow, the golden finger can form a loop through the metal pin of the card in the card tray, thereby causing a short circuit or burning the card. At present, the electronic device can periodically obtain the in-place detection signal of the card tray, and process the signal to obtain the in-place information of the card tray. If the in-place information of the card tray indicates that the card tray is not in place, the electronic device can send power-off indication information to the power management module through the analog-to-digital interface (Analog-to-Digital Interface, ADI), and the power management module can perform power-off processing on the card tray according to the power-off indication information. However, in the above method, the electronic device needs to periodically obtain the in-place detection signal and process the in-place detection signal, and the card tray is powered off through the in-place detection signal. There are more signal transmission paths, the signal processing and transmission delay is large, and the speed of the electronic device to power off the card tray is slow.

[0061] In order to solve the technical problems in the related art, the embodiment of the present application provides a power supply control method applied to an electronic device, which can include an external interrupt controller and a card holder, wherein the external interrupt controller is configured to input functions, and a pin of the external interrupt controller is connected with a signal line of a target signal; the electronic device can detect a level state corresponding to the target signal through the external interrupt controller, and obtain an interrupt trigger condition corresponding to the external interrupt controller; when the level state meets the interrupt trigger condition, it is determined that the level state triggers an interrupt, and the card holder is powered off. In this way, when the card holder is not in place, the electronic device can power off the card holder in time through the interrupt triggered by the external interrupt controller, and the electronic device does not need to convert the target signal of whether the card holder is in place into in-place information of the card holder, thereby improving the speed of powering off the card holder by the electronic device, avoiding the situation that the card in the card holder is burned out, and improving the safety.

[0062] Next, the architecture of the present application is described in combination with FIG. 1.

[0063] FIG. 1 is a schematic diagram of an architecture provided by an embodiment of the present application. Please refer to FIG. 1, which includes an electronic device. The electronic device can include a system on chip (SOC), a card holder, a power management unit, and a power supply. Optionally, the power management unit can be a power management integrated circuit (PMIC). The SOC can include an external interrupt controller (EIC). The card holder can include a subscriber identity module (SIM) card and a secure digital (SD) card. The EIC can be connected with the card holder and the PMIC, the PMIC can be connected with the power supply, and the power supply can power off the card holder. In this way, the electronic device can quickly power off the card holder through the interrupt triggered by the EIC, and improve the safety of the SIM card and the SD card.

[0064] Next, the technical solutions shown by the present application are described in detail through specific embodiments. It should be noted that the following embodiments can exist independently or be combined with each other, and the same or similar contents are not repeated in different embodiments.

[0065] FIG. 2 is a flowchart of a power supply control method provided by an embodiment of the present application. Please refer to FIG. 2, which can include the following steps:

[0066] S201, detecting a level state corresponding to a target signal through an external interrupt controller.

[0067] The execution subject of the embodiment of the present application can be an electronic device, or a power control device arranged in the electronic device. The power control device can be implemented according to software, or implemented according to a combination of software and hardware, and the embodiment of the present application does not limit this.

[0068] The target signal can be used to indicate whether the card tray is in place. For example, the target signal can be a SIM_DET signal, which can indicate whether the card tray is in place. For example, if the level state corresponding to the target signal is high, the target signal can indicate that the card tray of the electronic device is in place, and if the level state corresponding to the target signal is low, the target signal can indicate that the card tray of the electronic device is not in place. Alternatively, if the level state corresponding to the target signal is low, the target signal can indicate that the card tray of the electronic device is in place, and if the level state corresponding to the target signal is high, the target signal can indicate that the card tray of the electronic device is not in place.

[0069] The external interrupt controller can be used to process the interrupt signal of the external device, and the external interrupt controller is configured as an input function, and the pin of the external interrupt controller is connected with the signal line of the target signal. For example, the pin of the external interrupt controller can be connected with the signal line of the SIM_DET signal. Since the external interrupt controller is configured as an input function, the external interrupt controller can continuously detect the level state of the SIM_DET signal, and when the level state changes, the external interrupt controller can timely acquire the change.

[0070] Optionally, the electronic device can include a system on chip (SOC), and the external interrupt controller can be arranged in the SOC. In this way, when the external interrupt controller triggers an interrupt, the SOC can timely perform power-down processing on the card tray, thereby improving the speed of power-down and improving the security of the SIM card and the SD card.

[0071] S202, when the level state triggers an interrupt, powering down the card tray.

[0072] The electronic device can power down the card tray according to the following possible implementation manners: determining an interrupt trigger condition corresponding to the external interrupt controller, and when the level state meets the interrupt trigger condition, determining that the level state triggers an interrupt, and powering down the card tray.

[0073] The interrupt trigger condition can be a level trigger, and the level state meets the interrupt trigger condition, which can be specifically: if the level state is the same as the interrupt trigger level corresponding to the interrupt trigger condition, it is determined that the level state meets the interrupt trigger condition.

[0074] The interrupt trigger level can indicate a level triggering the interrupt. For example, if the interrupt trigger level is high, the external interrupt controller can trigger the interrupt when detecting that the level state of the target signal is high; if the interrupt trigger level is low, the external interrupt controller can trigger the interrupt when detecting that the level state of the target signal is low.

[0075] It should be noted that when the external interrupt controller triggers the interrupt, the status flag bit of the interrupt can be set to 1, and the SOC can detect the change of the status flag bit of the interrupt and perform the interrupt operation. After the SOC responds to the interrupt and powers off the card, the status flag bit of the interrupt can be cleared.

[0076] The interrupt trigger condition corresponds to an interrupt trigger level opposite to the level state of the target signal when the card is in place. For example, if the level state of the card in place is high, the interrupt trigger level corresponding to the interrupt trigger condition is low; if the level state of the card in place is low, the interrupt trigger level corresponding to the interrupt trigger condition is high.

[0077] Optionally, the interrupt trigger condition can be edge trigger, and the level state satisfying the interrupt trigger condition can be that if the level state of the target signal detected by the external interrupt controller appears a target edge, the electronic device can determine that the level state satisfies the interrupt trigger condition.

[0078] The target edge can indicate a signal edge triggering the interrupt. For example, if the target edge is a rising edge, the external interrupt controller can trigger the interrupt when detecting that the level state of the target signal rises from low to high; if the target edge is a falling edge, the external interrupt controller can trigger the interrupt when detecting that the level state of the target signal falls from high to low.

[0079] The setting of the target edge can be related to the level state of the card in place. For example, if the level state of the card in place is high, the target edge corresponding to the interrupt trigger condition can be a falling edge; if the level state of the card in place is low, the target edge corresponding to the interrupt trigger condition can be a rising edge.

[0080] Next, the level state of the target signal will be described in conjunction with FIG. 3-FIG. 4.

[0081] FIG. 3 is a schematic diagram of a level state of a target signal according to an embodiment of the present application. In the embodiment shown in FIG. 3, when the card is in place, the level state of the target signal is high. Referring to FIG. 3, a time axis is included. The level state of the target signal detected by the external interrupt trigger (not shown in FIG. 3) is included on the time axis. Before time t, the level state of the target signal is high, and after time t, the level state of the target signal is low. That is, before time t, the card is in place, and after time t, the card is not in place.

[0082] In the embodiment shown in FIG. 3, if the external interrupt controller detects that the level state of the target signal is low, or the level state of the target signal drops from high to low, the electronic device can determine that the level state meets the interrupt triggering condition, and the external interrupt controller can trigger an interrupt.

[0083] FIG. 4 is another schematic diagram of a level state of a target signal according to an embodiment of the present application. In the embodiment shown in FIG. 4, when the card is in place, the level state of the target signal is low. Referring to FIG. 4, a time axis is included. The level state of the target signal detected by the external interrupt trigger (not shown in FIG. 4) is included on the time axis. Before time t, the level state of the target signal is low, and after time t, the level state of the target signal is high. That is, before time t, the card is in place, and after time t, the card is not in place.

[0084] In the embodiment shown in FIG. 4, if the external interrupt controller detects that the level state of the target signal is high, or the level state of the target signal rises from low to high, the electronic device can determine that the level state meets the interrupt triggering condition, and the external interrupt controller can trigger an interrupt.

[0085] Optionally, when the level state of the target signal changes (for example, the card changes from being in place to not being in place), the SOC in the electronic device can perform debouncing processing on the level state of the target signal. In this way, the accuracy of the level state of the target signal can be improved, and false signals caused by mechanical jitter and the like can be avoided. Therefore, the electronic device can accurately determine whether the card is not in place, and the accuracy of powering off the card can be improved.

[0086] When the electronic device determines that the card is not in place, the PMIC can perform power-off processing on the SIM card and the SD card in the card. Before the electronic device powers off the card, the electronic device can perform power-off preparation operations. After the power-off preparation operations are completed, the electronic device can perform power-off processing on the card. For example, the power-off preparation operations can include data saving and synchronization, closing or suspending tasks that are running, and the like, which are not limited in the embodiments of the present application.

[0087] The embodiment of the present application provides a power supply control method, an electronic device can detect a level state corresponding to a target signal through an external interrupt controller, and obtains an interrupt trigger condition corresponding to the external interrupt controller, wherein the interrupt trigger condition can be a level trigger, if the level state is the same as an interrupt trigger level (opposite to the level state of the target signal when the card holder is in place) corresponding to the interrupt trigger condition, the electronic device can determine that the level state meets the interrupt trigger condition, and then determines that the level state triggers the interrupt, and powers off the card holder. In this way, when the card holder is not in place, the level state of the target signal can trigger the interrupt, the electronic device can timely power off the card holder, and the electronic device does not need to convert the target signal of whether the card holder is in place into in-place information of the card holder, thereby improving the speed of powering off the card holder of the electronic device, avoiding the situation that the card in the card holder is burned out, and improving safety.

[0088] On the basis of the embodiment shown in FIG. 2, the method that the electronic device powers off the card holder in the power supply control method will be described in detail below in combination with FIG. 5.

[0089] FIG. 5 is a schematic diagram of a method for powering off a card holder provided by an embodiment of the present application. Referring to FIG. 5, the method flow includes the following steps.

[0090] S501, determining a power-off signal.

[0091] The power-off signal can be used to instruct the power management unit to power off the card holder. For example, if the power management unit receives the power-off signal sent by the SOC, the power management unit can control the power supply to power off the card holder.

[0092] The power-off signal can be a high level or a low level. For example, the electronic device can pre-set a power binding relationship configuration, wherein the power binding relationship configuration can indicate the power-off signal. For example, the power binding relationship configuration can be high-level power-off, and the power binding relationship configuration can also be low-level power-off, and the embodiment of the present application does not make any limitation in this regard. In this way, the electronic device can control the power management unit to power off the card holder through the high level or the low level, the signal transmission and signal processing time is short, and then the speed of powering off the card holder can be improved.

[0093] It should be noted that the power-off signal can also be any other feasible signal (such as a rising edge signal or a falling edge signal), and the embodiment of the present application does not make any limitation in this regard.

[0094] S502, sending the power-off signal to the power management unit of the electronic device through a pre-set input / output (IO).

[0095] The preset IO can be dedicated to sending the power-off signal to the power management unit. For example, the preset IO can be a dedicated IO that sends the power-off signal to the PMIC when the card holder is pulled out, so the dedicated IO does not need to process other signals, the signal transmission speed is faster, and thus the power-off efficiency can be improved.

[0096] The preset IO can be a pin. For example, the preset IO can be a SIM INT pin that can be used as an interrupt pin, and the SIM INT pin can establish a dedicated communication interface between the SOC and the PMIC.

[0097] The embodiment of the present application provides a method for powering off the card holder. The electronic device can determine the power-off signal and send the power-off signal to the power management unit of the electronic device through the preset input / output IO. In this way, when the electronic device determines that the level state of the target signal meets the interrupt trigger condition, the power-off signal can be sent to the power management unit through the preset IO, and the power management unit can power off the card holder based on the power-off signal. Since the preset IO can be dedicated to synchronizing the power-off signal to the power management unit, the electronic device can quickly synchronize the power-off signal to the power management unit, thereby improving the speed of powering off the card holder and improving the security of the SIM card and the SD card.

[0098] Next, the process of the above power control method will be described in conjunction with FIG. 6.

[0099] FIG. 6 is a process schematic diagram of a power control method according to an embodiment of the present application. Please refer to FIG. 6, which includes an electronic device. The electronic device can include a SOC, a card slot shared by a SIM card and an SD card, a PMIC, and a power supply. The SOC can include an EIC and a dedicated IO, and the interrupt trigger condition of the EIC is a low-level trigger interrupt. When the card holder is inserted into the card slot shared by the SIM card and the SD card, the level state of the in-place detection signal of the card holder is high, the EIC can detect the high level, and the high level does not trigger an interrupt.

[0100] Please refer to FIG. 6, when the card holder is pulled out of the card slot shared by the SIM card and the SD card, the level state of the in-place detection signal of the card holder is low, and the EIC detects the low level. When the EIC detects the low level, it can determine that the low level triggers an interrupt, and the state flag of the interrupt is set to 1. After the SOC detects the state flag of the interrupt set to 1, the SOC can send a high level (configured as a high level power-off) to the PMIC through the dedicated IO. After the PMIC receives the high level, the PMIC can control the power supply to power off the card holder.

[0101] In this way, when the card holder is not in place, the electronic device can trigger an interrupt through the external interrupt controller, and can synchronize the power-down signal to the PMIC in a timely manner through the dedicated IO (small time delay and high transmission efficiency) to perform power-down processing on the card holder, thereby improving the power-down speed of the card holder, avoiding the burning of the SIM card and the SD card in the card holder, improving the safety, and when the SOC or the SIM module (a collection of hardware and software related to the SIM card) is in a sleep scenario, the electronic device does not need to go through the wake-up process to directly synchronize the PMIC power-down, and the fast power-down demand in the sleep scenario can be met.
