The following first presents some concepts related to embodiments of the present application.

(1) Dual-mode card and single-mode card

The SIM card is a subscriber identity card of a digital cellular mobile network. When the electronic equipment is accessed to the network, the network side can carry out customer identity authentication through the information provided by the SIM card, and encrypt the voice information when the customer calls.

The card application of the SIM card is a directory or a file in the SIM card, and the types of the card application may include USIM card application and CSIM card application.

Wherein, the card application of the CSIM application stores card files required by Code Division Multiple Access (CDMA) and evolution data optimized (EVDO) registration (namely CDMA 20001 xEV-DO); the USIM application stores card files required for global system for mobile communications (GSM), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), and New Radio (NR) registration.

SIM cards may contain different numbers of card applications. SIM cards can be classified into dual mode cards and single mode cards according to the number of card applications included in the SIM cards. A dual mode card is a SIM card that contains two card applications, for example, the SIM card's card applications include USIM and CSIM. A single mode card is a SIM card containing one card application, e.g. the SIM card comprises a USIM or a CSIM. In the dual-mode card, the electronic device can respectively establish two file systems (card applications) with different systems on the same SIM card, and the two file systems and the card applications can respectively carry out independent reading and operation without mutual influence.

(2) Card file and key card file of SIM card

Different card files may be stored in different card applications in the SIM card, and the card files stored in the SIM card may include: international Mobile Subscriber Identity (IMSI), ISMI is used for access authentication; mobile subscriber number (MSISDN); secret key Ki, encryption algorithm A3, A8, for authentication; a Mobile Country Code (MCC), a Mobile Network Code (MNC) of a Public Land Mobile Network (PLMN) to which the mobile country code belongs, a network identifier, a personal identification number, an unlock number, and the like.

In the card application, some key card files are stored, and the key card files can be used for supporting the electronic equipment to perform processes such as network injection and the like, so that the electronic equipment can use functions such as telephone, short message and data network.

The key card files stored in the USIM application may include: international Mobile subscriber identity (IMSI, E)F_IMSI) Location information (EF)_LOCI) Forbidden home public land mobile network (Forbid PLMN, EF)_FPLMN) And so on. The basic file ef (elementary file) is a file in the SIM card file system.

The key card files stored in the CSIM application may include: international Mobile subscriber identity EF_{IMSI_M}(IMSI_M)、EF_USGIMD(usementor) and EF_SP(service reference) and the like.

The above key card file is for illustration and not limited.

(3) Use of SIM cards

The SIM card is a smart chip card equipped with a microprocessor, and may include modules such as a processor, a working memory, a program memory, and a data memory, wherein the processor may execute instructions of the program memory, and the processor may also read from and write to the data memory. Wherein different card files can be stored in the data memory.

The use of SIM cards often has a certain age limit. The service life of the SIM often depends on the number of plugging and unplugging users and the number of reading and writing data memories. The upper limit of the number of times of plugging and unplugging the SIM card by the user is generally about 1 ten thousand times. The upper limit of the read-write times of the processor of the SIM card to the data memory is related to the index of a manufacturer and is not limited. The longer the SIM is used, the greater the possibility of damage, and the upper limit of SIM use is generally about 4/5 years.

The Application framework layer provides an Application Programming Interface (API) and a Programming framework for the Application program of the Application layer. The application framework layer includes a number of predefined functions.

As shown in FIG. 2, the application framework layers may include a telephony manager, content provider, view system, window manager, resource manager, notification manager, and the like.

The phone manager is used to provide communication functions of the electronic device 100. Such as management of the status of the calling card (including connection, hang-up, etc.).

Content providers are used to store and retrieve data and make it accessible to applications. The data may include phone calls made and received, browsing history and bookmarks, phone books, etc.

The view system includes visual controls such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, the display interface including the short message notification icon may include a view for displaying text and a view for displaying pictures.

The window manager is used for managing window programs. The window manager can obtain the size of the display screen, judge whether a card status bar exists, lock the screen, intercept the screen and the like.

The resource manager provides various resources for the application, such as localized strings, icons, pictures, layout files, video files, and the like.

The notification manager enables the application to display notification information in the card status bar, can be used to convey notification-type messages, can disappear automatically after a brief dwell, and does not require user interaction. Such as a notification manager used to inform download completion, message alerts, etc. The notification manager may also be a notification that appears in the form of a chart or scroll bar text on the top card status bar of the system, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog interface. For example, prompting text information on the card status bar, sounding a prompt tone, vibrating the electronic device, flashing an indicator light, etc.

The Runtime (Runtime) includes a core library and a virtual machine. Runtime is responsible for scheduling and management of the system.

The core library comprises two parts: one part is a function that a programming language (for example, java language) needs to call, and the other part is a core library of the system.

The application layer and the application framework layer run in a virtual machine. The virtual machine executes programming files (e.g., java files) of the application layer and the application framework layer as binary files. The virtual machine is used for performing the functions of object life cycle management, stack management, thread management, safety and exception management, garbage collection and the like.

The system library may include a plurality of functional modules. For example: surface Manager (Surface Manager), Media Libraries (Media Libraries), three-dimensional graphics processing Libraries (e.g., OpenGL ES), two-dimensional graphics engines (e.g., SGL), and the like.

The surface manager is used to manage the display subsystem and provides a fusion of two-Dimensional (2-Dimensional, 2D) and three-Dimensional (3-Dimensional, 3D) layers for multiple applications.

The media library supports a variety of commonly used audio, video format playback and recording, and still image files, among others. The media library may support a variety of audio-video encoding formats, such as MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, and the like.

The three-dimensional graphic processing library is used for realizing 3D graphic drawing, image rendering, synthesis, layer processing and the like.

The 2D graphics engine is a drawing engine for 2D drawing.

The Hardware Abstraction Layer (HAL) is the interface Layer between the kernel Layer and the Hardware Layer. The hardware abstraction layer may include a Radio Interface Layer (RIL). Where the RIL provides telephony services, etc.

The kernel layer is a layer between hardware and software. The kernel layer at least comprises a display driver, a camera driver, an audio driver, a sensor driver and a virtual card driver.

The hardware layer includes at least a Modem (Modem), which is an electronic device capable of implementing modulation and demodulation functions. The Modem can be used for communicating with a base station, carrying out data transmission with the RIL layer and controlling the power-on and power-off of the SIM card.

In the embodiment of the present application, the RIL is a communication request sent to an application program and may include two parts, rild and Vendor RIL, where the rild is responsible for communicating with the application framework layer through an interface socket or a hardware abstraction definition language (HIDL). This part of the Vendor RIL is responsible for communication down to the Modem at the hardware level. For example, the Vendor RIL may communicate with the Modem via AT command channels, or via channels defined by different vendors.

In the embodiment of the application, in the process of initializing the SIM card, the Modem can identify whether the SIM card holder is inserted into the SIM card. The Modem can also determine the power-up and power-down of the SIM card. The Modem can also receive a power-on instruction from the RIL and perform a power-on operation in response to the power-on instruction. The Modem can also read each card file of the SIM card, and the like, and in this process, the Modem can report the account status (card account status) of the card application that acquires the SIM card. Further, after SIM card initialization and reading are successful, the SIM card may periodically poll the card. The SIM card may determine whether the card is still, whether the interaction is normal, etc. by polling the card. In the process of polling the card, the SIM card can apply the account state to the cards of ModemUSIM and CSIM under the condition that the account state changes.

Fig. 3 is a schematic diagram of a software structure of another electronic device 100 according to an embodiment of the present application.

As shown in fig. 3, the electronic device may include an application layer, an application framework layer, a hardware abstraction layer, and a hardware layer.

The application program layer may include applications such as short messages and calls, and may also include other applications.

The application framework layer can comprise a telephone manager, a short message manager, an SIM card manager, a network manager, a resource manager, a notification manager and the like.

In addition, the application framework layer also comprises RILJ (radio interface layer java), and the RILJ can send and receive information to and from the SIM card manager and the like through the interface.

The hardware abstraction layer may include rlc (radio interface layer C + +), the rlc includes a Radio Interface Layer Daemon (RILD) and a radio interface layer Vendor _ RIL, and the RILD and RILJ communicate with each other through an interface (socket) or hidl. And the Vendor _ RIL is matched with a Modem (Modem), and the RILD and the Vendor _ RIL need to perform instruction conversion according to a matching result.

The hardware layer can comprise a Modem and a SIM, wherein the Modem can communicate with the Vendor _ RIL, and the Modem can read the card file of the SIM card.

Illustratively, the RILD may suggest a listening interface, wait for the client's connection, and then enter a time queue eventloop loop. When the RILD receives a command from RILJ, the command is converted into an AT command and sent to the Modem through the serial port. Meanwhile, the RILD waits for the response of the Modem when the read queue readerlopopter circulates, and then the result is transmitted back to the RILJ through the socket.

It should be noted that, the channels and interfaces between the different layers may be different according to different manufacturers, and the specific channels and interfaces are also different.

In the SIM dual mode card, since the key card file applied to a certain card stored in the SIM card may be damaged or lost during the process of plugging or reading/writing. At this time, when the electronic device cannot read the required key card file of the USIM application or the CSIM application through the modem. That is, when a key card file in a certain card application is damaged or lost, the electronic device cannot detect the ready account status (app state) of this card application. For example, when the key file IMSI in USIM application is damaged in the process of plugging and unplugging, the electronic device will detect that the account status of the USIM is detected.

Based on the above description, the following describes the reporting process of the SIM card status (card state) in the case of normal SIM card status and abnormal SIM card status in the SIM dual mode card.

After the Modem of the electronic device determines the account status of the USIM and the CSIM, the account status information of the USIM and the CSIM can be reported to the RIL. When the RIL receives the account status information from the Modem, the account status information of the USIM and the CSIM may be reported to the Framework layer. When the Framework receives the account state information from the RIL, the card state information of the SIM card can be determined according to the account state information, and the card state information of the SIM card is reported to the application program layer.

The method for determining the card status information of the SIM card by the electronic device through the Framework according to the USIM and CSIM account status information includes four conditions: when account states of USIM and CSIM card applications are both not ready (e.g., detected), determining that card state information of the SIM card is not ready; secondly, when the account state of the USIM is not ready and the account state of the CSIM is ready, determining that the card state information of the SIM card is not ready (for example detected); thirdly, when the account state of the USIM is ready and the account state of the CSIM is not ready, determining the card state information of the SIM card to be not ready; and fourthly, when the account states of the USIM and the CSIM are both ready, determining the card state information of the SIM card as ready.

When the SIM card is in ready state, the electronic equipment can normally use functions of telephone, short message, internet access and the like, and otherwise, the functions cannot be used.

Embodiment 1: and when the SIM dual-mode card is not damaged (the USIM and CSIM card applications in the SIM card are normal), the account state of the card application and the card state of the SIM card are reported.

Over time, the account states of the USIM and the CSIM are changed from not ready to ready, and when the card states of the USIM and the CSIM are changed to ready, the electronic equipment can determine that the card state of the SIM card is ready. In this process, the electronic device may determine that the card status of the SIM card changes from not ready to ready. When the card state of the SIM card is ready, the electronic equipment can normally use functions of telephone, short message, internet access and the like.

Fig. 4 is a schematic diagram illustrating a reporting process of a card status of a SIM card.

Typically, the electronic device may periodically query the SIM card for its card status (within 30 seconds of protocol specification). When a user just opens the electronic equipment or after the SIM card is hot-plugged, the electronic equipment needs a certain time to read the account status of USIM and CSIM card applications, namely the account status is gradually changed. For example, when the card file of the SIM card is not damaged or lost, at time T1, when the electronic device has not yet queried the account status of the card application, the account statuses of the USIM and the CSIM are both detected, and the card status of the SIM card is not ready; at a time T2, the account status of the USIM card application queried by the electronic device changes, that is, the account status of the USIM card application is ready, the account status of the CSIM card application is detected, and the card status of the SIM card is still not ready; at time T3, the account status of the CSIM card application queried by the electronic device is changed to ready, at this time, the account statuses of the USIM and the CSIM are both ready, and the card status of the SIM card is changed to ready.

As shown in fig. 4, at time T1, when the Modem detects that the account statuses of the USIM and the CSIM are both detected, the electronic device executes step S401, that is, the Modem may report the account status information of the USIMdetected and the CSIMdetected to the RIL. After the RIL receives the account status information of USIMdetected and CSIMdetected from the Modem, step S402 is executed to forward the account status information of USIMdetected and CSIMdetected to the Framework. After the Framework receives the account status information of the usimderted and the CSIMdetected from the RIL, it may determine that the card status of the SIM card is not ready, and perform step S403, that is, send the card status information of the SIM card to the application layer. When the Framework determines that the current card state of the application SIM card is not ready, the Framework can broadcast the card state of the SIM card to the outside, namely the Framework can send the card state information of the SIM card to the manager and the server. When each manager or server of the electronic equipment needs to use the card state information of the SIM card, corresponding operation is executed according to the corresponding card state information. At this time, the electronic device cannot use services such as telephone, short message, and internet access.

At time T2, when the Modem determines that the account status of the USIM card application is ready and the account status of the CSIM card application is detected, the electronic device executes step S404, that is, the Modem may report the account status information of the USIMdetected and the CSIMdetected to the RIL. After the RIL receives the account status information of USIMdetected and CSIMdetected from the Modem, step S405 is executed to forward the account status information of USIMdetected and CSIMdetected to the Framework. After the Framework receives the account status information of the USIMdetected and the CSIMdetected from the RIL, it may determine that the card status of the SIM card is not ready, and perform step S406, that is, send the card status information of the SIM card to the application layer. When the Framework determines that the card status of the currently applied SIM card is not ready, the card status of the SIM card may be broadcast outwards as not ready. At this time, the electronic device cannot use services such as telephone, short message and internet access.

At time T3, when the Modem determines that the account statuses of the USIM and the CSIM are both detected, the electronic device executes step S407, that is, the Modem may report the account status information of the USIMdetected and the CSIMdetected to the RIL. After the RIL receives the account status information of USIMdetected and CSIMdetected from the Modem, step S408 is performed, i.e., the account status information of USIMdetected and CSIMdetected is forwarded to the Framework. After the Framework receives the account status information of the USIMdetected and the CSIMdetected from the RIL, it may determine that the card status of the SIM card is not ready, and perform step S409, that is, send the card status information of the SIM card to the application layer. When the Framework determines that the card status of the current application SIM card is ready, the card status of the SIM card may be broadcast to the outside, and it may be determined that all applications have been initialized. At this time, the electronic device can use the services such as telephone, short message and internet access.

The time points are respectively the time point T1, the time point T2 and the time point T3.

In the case where the SIM card is made normal by the electronic device, the user interface of the electronic device may change from the user interface with abnormal SIM card state to the user interface with normal SIM card state from time T1 to time T3 as time passes.

FIG. 5A shows a schematic diagram of a user interface.

Illustratively, as shown in fig. 5A (a), the schematic includes a card status bar 110 and a menu bar 120. The card status bar 110 includes an operator, a current time, a network card status 111, a signal card status 111, and a power supply capacity. The current time is 15: 56; the black portion of the power supply capacity may represent the remaining capacity of the electronic device, which is 38%. Menu bar 120 includes icons for at least one application, each having a name for the corresponding application below the icon, for example: gallery 124, settings 125, camera 126, phone 121, text message 122, and address book 123. The positions of the icons of the application programs and the names of the corresponding application programs may be adjusted according to the preference of the user, which is not limited in the embodiment of the present application.

As shown in fig. 5A (a), the network card status 111 indicates a no-signal status, and an "x" in the network card status 111 indicates a no-network status in the user interface at time T1.

The user interface at time T2 is shown in fig. 5A (b), and the network card status 211 is still no signal and no network, as the interface is used at time T1.

As shown in (c) of fig. 5A, in the user interface at the time T3, in the 5G data traffic network, the signal card state 311 is a full signal, which indicates that the current signal is strong, and 5G indicates that the current network is a 5G mobile data network; the operator 312 is china mobile; when the card status of the SIM is ready, the electronic device may display a network card status of a 5G data traffic network, as shown in (c) of fig. 5A, indicating that the user may use 5G data traffic.

The descriptions of (b) and (c) in fig. 5A may refer to the description of (a) in fig. 5A, and are not repeated.

FIG. 5B shows a schematic view of another user interface.

For example, the description of (a) in fig. 5B may refer to the description of (a) in fig. 5A. The user may click on the settings icon. In response to the user operation, the cellular phone may display the user interface of fig. 5B (B).

Controls such as WLAN controls, bluetooth controls, mobile network controls, and display controls may be included in the user interface of (B) in fig. 5B. The user may click on the mobile web control 311. In response to the user operation, the handset may display the user interface of fig. 5B (c).

A mobile data bar 410 and a SIM card control bar 420 may be included in the user interface of fig. 5B (c). The SIM card control bar 420 may include a data roaming control 421, an access point name control (APN) 422, a network mode control 423, and a network operator control 424. The user interface may further include other controls, which is not limited in this embodiment of the present application.

As shown in fig. 5B (c), the user interface at time T1 is that all icons and controls in the SIM card control bar 420 are gray, which indicates that the card status of the SIM card is not ready, and at this time, the user interface indicates that no network service is available.

User interface at time T2 as shown in fig. 5B (d), all icons and controls in the SIM card control bar are grey, the same as the user interface at time T1, i.e., network services are not available.

User interface at time T3 as shown in fig. 5B (e), the SIM card control bar changes, which may include data roaming control 521, access point name control (APN)522, network operator control 524, and start 5G control 525. The above controls can be operated by the user, for example, an icon corresponding to the control 525 is displayed, the current electronic device is in a state of opening the 5G network, and the user can click the control to close the 5G network. At time T3, the user interface indicates that network services of the SIM card are available.

The descriptions of (d) and (e) in fig. 5B may refer to the description of (c) in fig. 5B, and are not repeated.

Fig. 5A and 5B are user interfaces that may be displayed by the electronic device in the process of changing the card status of the SIM card from not ready to ready, which is not limited.

Embodiment 2: and when the SIM dual-mode card is damaged (one of USIM and CSIM card in the SIM card is in a normal state), reporting the card state of the SIM card.

When the key card file of one card application in the SIM dual-mode card is damaged or lost, the state of one account of the USIM card application and the CSIM card application is always not ready. At this time, the electronic device may determine that the card status of the SIM card is always maintained at not ready. The Framework always broadcasts the card state of the SIM card as notreaty to the outside. The electronic device can not normally use the functions of telephone, short message, internet access and the like.

Fig. 6 is a schematic diagram illustrating a reporting process of a card status of another SIM card.

When a key card file of one card application of the SIM is lost or damaged, the account state of the one card application inquired by the electronic equipment cannot be updated to ready. For example, when the electronic device is just started or a user performs hot plug on a SIM card (a key card file of the CISM is lost), at time T4, when the electronic device has not yet reached the account status of the inquiry card application, the account statuses of the USIM and the CSIM are both detected, and the card status of the SIM card is not ready; at time T5, the account status of the USIM card application queried by the electronic device changes, that is, the account status of the USIM card application is ready, the account status of the CSIM card application is detected, and the card status of the SIM card is still not ready.

As shown in fig. 6, at time T4, when the Modem detects that the account statuses of the USIM and the CSIM are both detected, the electronic device executes step S601, that is, the Modem may report the account status information of the USIMdetected and the CSIMdetected to the RIL. After the RIL receives the account status information of USIMdetected and CSIMdetected from the Modem, step S602 is executed to forward the account status information of USIMdetected and CSIMdetected to the Framework. After the Framework receives the account status information of the usimderted and the CSIMdetected from the RIL, it may determine that the card status of the SIM card is not ready, and perform step S603, that is, send the card status information of the SIM card to the application layer. When the Framework determines that the card status of the currently applied SIM card is not ready, the card status of the SIM card may be broadcast outwards as not ready. At this time, the electronic device cannot use services such as telephone, short message, and internet access.

At time T5, when the Modem determines that the account status of the USIM card application is ready and the account status of the CSIM is detected, the electronic device executes step S604, that is, the Modem may report the account status information of the USIMdetected and the CSIMdetected to the RIL. After the RIL receives the account status information of USIMdetected and CSIMdetected from the Modem, step S605 is executed to forward the account status information of USIMdetected and CSIMdetected to the Framework. After the Framework receives the account status information of the usimderted and the CSIMdetected from the RIL, step S606 is executed, that is, the card status of the SIM card is determined to be not ready, and the card status information of the SIM card is sent to the application layer. When the Framework determines that the card status of the currently applied SIM card is not ready, the card status of the SIM card can be broadcasted outwards to be not ready. At this time, the electronic device is not able to use services such as telephone, short message, and internet access.

The time points are respectively the time point T4 and the time point T5 in sequence according to the chronological order.

When the electronic device makes the SIM card abnormal, the user interface of the electronic device may display the user interface with abnormal SIM card status from time T4 to time T5 as time goes by. It may be understood that the user interface may also display other user interfaces, which is not limited in this embodiment of the present application.

FIG. 7A shows a schematic view of yet another user interface.

For example, when the card status of the SIM card is notreaty, the electronic device may display the user interface as shown in fig. 7A from time T4 to time T5. As shown in fig. 7A, the traffic card status is no signal, and the network card status is no data traffic network, indicating that no signal is currently available. The description of fig. 7A may refer to the description of (a) in fig. 5A, which is not repeated.

FIG. 7B shows a schematic view of yet another user interface.

For example, when the card status of the SIM card is notreaty, the electronic device may display a user interface as shown in fig. 7B from time T4 to time T5. As shown in fig. 7B, all icons and controls in the SIM card control bar are grey, and network services are not available. The description of fig. 7B may refer to the related description of (c) in fig. 5B, and details are not repeated.

In the time after T5, the electronic device detects that the card status of the SIM card is still not ready, and therefore, the electronic device cannot use services such as telephone, sms, internet, and the like.

Fig. 7A and 7B are user interfaces that may be displayed by the electronic device when the card status of the SIM card is not ready, which are not limited.

It should be further noted that, under the condition that different card applications are abnormal, the abnormality presented by the electronic device is different between different chip manufacturers and terminal manufacturers, and therefore, the service of the call, the short message or the data traffic and the abnormality displayed in the menu are all exemplified, and the specific situation is not limited.

In the implementation manner, after the SIM card is inserted, plugged, read, and written for multiple times, some key card files of the SIM may be damaged or lost, and when the electronic device cannot read a required key card file through the modem, a USIM of the electronic device or a card application (application) of the CSIM may not enter a normal account state. Therefore, under the condition of the SIM dual-mode card, when one card application cannot enter the normal account state and the other card application already enters the normal account state, the electronic device cannot use services such as a mobile network, a telephone or a short message, and the user experience is poor.

In view of the problems in the foregoing embodiments, an embodiment of the present application provides an optimization method for an abnormal SIM dual mode card, where when an electronic device detects that one of two card applications, namely a USIM and a CSIM, cannot enter a normal account state, and the other card application already enters the normal account state, the electronic device may close the card application that cannot enter the normal account state, and report the card application that enters the normal account state, and the electronic device may determine that the card state of the SIM card is the normal state, so that services such as a mobile network, a telephone, or a short message may be used normally. Thus, the user experience is improved.

Referring to fig. 8, fig. 8 is a schematic flowchart of a method for optimizing an exception of a SIM dual mode card according to an embodiment of the present application, where the method may be executed by the electronic device shown in fig. 8, and may also be executed by some modules in the electronic device, and the method may include, but is not limited to, the following steps:

s101, under the condition that the account states of the USIM and the CSIM are detected to be preset states, the electronic equipment closes the first card application.

Illustratively, the first card application may be closed by the Modem.

The method for detecting account statuses of the USIM and the CSIM by the electronic device may refer to the method shown in fig. 6, where in a possible case, when the electronic device performs the step shown in step S604 in fig. 6, the electronic device may determine to start a Timer (Timer), and when the Timer is over, the electronic device may close the first card application. In another possible case, the electronic device may directly close the first card application when the electronic device performs the steps as shown in step S604 in fig. 6.

There are two account states of the USIM and the CSIM, namely, a normal state (e.g., ready) and an abnormal state (e.g., not ready). The preset state is in two card applications of USIM and CSIM, one account state is ready, and the other account state is not ready. For example, the account status of the USIM is ready, and the account status of the CSIM is not ready; the account status of the CSIM is ready, and the account status of the USIM is not ready. The card status of the SIM card is also classified into a normal status and an abnormal status.

Under the condition that the account states of the USIM and the CSIM detected by the electronic device are in the preset states, the electronic device may close the first card application, where the first card application is a card application with an account state that is an abnormal state, and closing the first card application means deactivating the card application with the account state that is an abnormal state, that is, closing an interaction channel (related process) of the card application with the account state that is an abnormal state. For example, when the account status of the USIM is ready and the account status of the CSIM is not ready, the electronic device may deactivate the CSIM through the Modem; when the account status of the CSIM is ready and the account status of the USIM is not ready, the electronic equipment can deactivate the USIM through the Modem.

The advantage of this approach is that the user can also use other card applications when one card application is not available. For example, when the CSIM account status is abnormal and the USIM account status is normal, the user can use the USIM account to surf the internet normally, so that the network use of the user is not affected.

When the electronic device detects that the account status of the USIM and the CSIM is the preset status, closing the first card application may include the following:

embodiment 1: under the condition that the RIL detects that the account states of the USIM card application and the CSIM card application meet the preset state, closing the first card application based on the duration time meeting the preset state; or, when the RIL detects that the account state of one card application is abnormal, the first card application is directly closed.

In the foregoing manner, fig. 9 shows a schematic flowchart of a process for closing the first card application, and as shown in fig. 9, S101 may include, but is not limited to, the following steps:

s201, the Modem reports the account states of the USIM card application and the CSIM card application to the RIL.

In the case that the Modem detects the account status of the USIM and the CSIM, the Modem may report the account status of the USIM and CSIM two card applications to the RIL. Correspondingly, the RIL receives the account status of the USIM and the CSIM from the Modem, where the reporting process may refer to the related description of S604 shown in fig. 6, which is not repeated.

S202, under the condition that the RIL detects that the account states of the USIM card application and the CSIM card application meet the preset state, closing the first card application based on the duration time meeting the preset state; or when the RIL detects that the account state of one card application is abnormal, the first card application is directly closed.

In one possible implementation, in the case that the RIL acquires the information of the account statuses of the USIM and the CSIM, it is determined whether the account statuses of the USIM and the CSIM are the preset status. When the account status of the USIM and CSIM satisfies the preset status, a Timer (Timer) may be started to determine the duration of satisfying the preset status. When the duration is greater than the first time threshold, the RIL performs step S203.

For example, the first time threshold may be in a range of 1-5s, and the specific range is not limited.

When the duration is not greater than the first time threshold, the electronic device may end the counting of the timer, and not perform step S203. In a possible case, when the electronic device does not reach the first time threshold value, and the acquired account states of the USIM and the CSIM change from the preset state to the preset state, the electronic device may stop timing. For example, when the electronic device acquires the USIM ready and the CSIM detected, the electronic device stops timing if the USIM ready and the CSIM ready are received within 5 s. In another possible case, the electronic device may restart timing when the acquired account states of the USIM and the CSIM change from the state satisfying the preset state to another state satisfying the preset state when the first time threshold is not reached. For example, when the RIL receives USIM ready and CSIM ready within 5s, and receives USIM ready and CSIM ready again, the RIL stops this timing and counts again.

In another possible embodiment, in the case where the RIL acquires information on the account status of the USIM and the CSIM, it is determined whether the account status of the USIM and the CSIM is a preset status. The RIL may close the first card application on condition that the preset state is satisfied, i.e., the RIL deactivates all interaction channels of the first card application. At this time, step S203 and step S204 are not performed.

S203, RIL sends a closing command to the Modem.

Wherein the instruction to close (deactivate) is an instruction to deactivate the card application whose account status is an abnormal status.

S204, the Modem closes the first card application.

When the Modem receives the close command, the Modem may close the first card application.

Illustratively, the Modem sends account status information of USIM ready and CSIMprotected to the RIL, and when the RIL receives the information, the RIL starts to count by a timer, and when the time is greater than the first time threshold value 5s, the RIL sends an instruction for closing the CSIM to the Modem. When the Modem receives the command of closing the CSIM, the Modem can deactivate the CSIM card application.

It should be noted that, the steps executed by the electronic device through the RIL may also be completed by other modules of the electronic device, for example, a Modem and a Framework, and the embodiments of the present application are not limited.

Embodiment 2: when the Modem detects the account state preset states of the USIM and the CSIM, the card application with the abnormal account state is reported to the RIL, the RIL issues a closing instruction to the Modem, and the Modem closes the first card application.

In the foregoing manner, fig. 10 shows another schematic flow chart of closing the first card application, and as shown in fig. 10, S101 may include, but is not limited to, the following steps:

and S301, the Modem reports the account state information of the first card application or the second card application to the RIL.

When the Modem detects that the account states of the two card applications of the USIM and the CSIM meet the preset state, the Modem reports the account state information of the first card application or the second card application to the RIL.

The first card application is a card application with an abnormal account state in the USIM and CSIM card applications, and the second card application is a card application with a normal account state.

In one case, the Modem reports the account status of the first card application to the RIL, and after receiving the account status of the first card application from the Modem, the RIL may determine that the first card application cannot be used any more, that is, step S302 may be performed. For example, the Modem reports the USIM detected to the RIL, and the RIL can issue an instruction to close the USIM.

In another case, the Modem reports the account status of the second card application to the RIL, and after receiving the account status of the second card application from the Modem, the RIL may determine that the second card application is usable, but the first card application is not usable, that is, step S302 may be executed.

S302, RIL sends a close command to the Modem.

In step S302, reference may be made to the relevant description in step S203, which is not repeated herein.

S303, the Modem closes the first card application.

In step S303, reference may be made to the relevant description of steps S101 and S203, which is not repeated herein.

Illustratively, when the Modem detects that the current card application is USIM ready and CSIM protected, the electronic device may send CSIM protected information to the RIL. After receiving this information, the RIL may issue a close command to the Modem, and the Modem may close the CSIM.

Embodiment 3: and when the Modem detects that the account states of the USIM and the CSIM are the preset states, the Modem directly closes the first card application.

In the foregoing manner, fig. 11 shows a schematic flowchart of another procedure for closing the first card application, and as shown in fig. 11, S101 may include, but is not limited to, the following steps:

s401, when the Modem detects that the account state of the USIM and the CSIM is a preset state, the Modem closes the first card application.

Here, step S401 may refer to the relevant description of steps S101 and S203.

Illustratively, the Modem may directly deactivate the CSIM when the Modem detects that the account status of the current card application is usimread and CSIM protected.

In one possible implementation, the electronic device checks the account status of the USIM and the CSIM by the Modem querying the key card file of the SIM card. When the electronic equipment queries key card files corresponding to the USIM application and the CSIMapplication through the Modem, whether the account states of the USIM and the CSIM are normal or abnormal can be determined. That is, when the modem reads the usimaplication in the SIM card, and cannot read a complete key card file or read a key card file cannot be identified, it may be determined that the account status of the USIM is an abnormal status, otherwise it is a normal status. The account status of the CSIM may be obtained in the same way.

For example, when the key card file of the USIM stored in the SIM card of the current electronic device lacks an IMSI card file, and the key card file of the CSIM is not damaged or missing, the electronic device may read the USIM and the CSIM by a Modem, detect that the IMSI card file is missing in the key card file of the USIM and the key card file of the CSIM is not damaged or missing, and may determine that the account status of the USIM is detected and the account status of the CSIM is ready.

It should be noted that, before executing step S101, for example, the execution of the electronic device is performed in the case of an abnormal SIM card, reference may be specifically made to the relevant description of embodiment 2 corresponding to fig. 6, which is not repeated herein. At this time, both the CSIM and USIM of the card application are in an activated state, that is, the interaction channel modems of both the card applications are opened.

And S102, the electronic equipment reports the account state information of the second card application to a Radio Interface Layer (RIL) through a Modem (Modem).

Correspondingly, the RIL receives account status information from the second card application of the Modem. The second card application is a card application with the account status in a normal state in the USIM and the CSIM, and the second card application is one of the USIM and the CSIM.

At this time, after the first card application is closed, the card application in the activated state only has the second card application, and the Modem may report the account status of the second card application. Unlike time T2 of fig. 4, the only information reported in S102 is the account status information of only one card application, and fig. 4 includes the account status information of two card applications.

In a possible case, when the electronic device detects that the account status of the USIM is a normal state and the account status of the CSIM is an abnormal state, the account status information of the second card application reported by the modem to the RIL is the usimready.

In another possible case, when the electronic device detects that the account status of the CSIM is a normal status and the account status of the USIM is an abnormal status, the account status information of the second card application reported by the modem to the RIL is CSIM ready.

S103, the electronic equipment reports the account state information of the second card application to the Framework through a Radio Interface Layer (RIL).

The account status information of the second card application in S103 and S102 is the same as the indicated account status information. However, before reporting the account status information to the Framework by the RIL, instruction conversion is required.

In a possible case, when the account status information applied by the second card is USIM ready, the card status information of the SIM card reported by the RIL to the Framework is USIM ready.

In another possible case, when the account status information applied by the second card is CSIM ready, the card status information of the SIM card reported by the RIL to the Framework is CSIM ready.

S104, the electronic equipment reports the card state information of the SIM card to an application layer (Apps) through the Framework.

The first card application and the second card application are both card applications of the SIM card.

In a possible implementation manner, when the electronic device determines that the card state of the SIM card is a normal state through the Framework, the card state information of the SIM card may be reported to the application layer.

The Framework of the electronic equipment can judge the card status of the SIM card according to the account status information applied by the USIM card and the CSIM card. In case only account status information of one card application is included in the account status information, this one account status (account status of CSIM or USIM) determines the card status of the SIM card. The Framework can judge the card status of the SIM card according to the account status information applied by the USIM and the CSIM card, and the conditions comprise that: when the account status information applied by the second card is USIM ready, SIM ready can be determined; when the account status information of the second card application is CSIM ready, SIM ready can be determined; when the account status information of the second card application is USIM detected, SIM not ready can be determined; when the account status information of the second card application is CSIM detected, the SIM not ready may be determined.

S105, the electronic equipment displays the first prompt message.

The electronic device determines that the user may be prompted for a SIM anomaly, e.g., the electronic device may prompt the user to replace a SIM card.

In one possible implementation, the electronic device may report the prompt information to the application layer through the RIL. The prompt message is used for indicating the application program layer to prompt the user that the current SIM card is abnormal. When the application layer receives the prompt message from the RIL, the first prompt message can be displayed through the display screen. The first prompt message is to prompt the user that the currently used SIM card is abnormal.

According to the above description of closing the first card application, the reporting of the prompt information to the application layer by the RIL may include the following cases:

in one possible implementation, in combination with embodiment 1 and embodiment 2 in step S101, when the RIL determines that a close instruction is to be sent to the Modem, the RIL may instruct the application layer to send a prompt message. That is, when the electronic device wants to close a certain SIM card, the user may be prompted that the SIM card is damaged. The prompting mode can be a character, or different modes such as voice, flash and the like. The electronic equipment can also prompt the user that the SIM card is damaged and needs to be replaced through the wearable equipment. For example, the electronic device may text prompt the user for a CSIM card corruption or a USIM card corruption.

In another possible implementation manner, in combination with implementation manner 3 in step S101, when the RIL determines to receive the account status information of one card application (the account status information of a second card application), the RIL may prompt the application layer to send the first prompt message.

In some embodiments, the electronic device may pop up a prompt window in the display screen, and the prompt window may display the first prompt message. Fig. 12 is a schematic diagram of another user interface shown in the embodiment of the present application. As shown in fig. 12, the electronic device may display a prompt window in the user interface, where the first prompt information is displayed in the prompt window. The first prompt message is that the SIM card is damaged and the SIM card is required to be replaced.

In other embodiments, the electronic device may display a notification window in the display screen, and the notification window may display the first prompt message. Fig. 13 is a schematic diagram of another user interface shown in the embodiment of the present application. As shown in (a) in fig. 13, the user can open an operation of the interface of the notification bar, for example, an operation of a page that the user swipes down. In response to an operation of opening the notification bar interface, the electronic device may display as in (B) of fig. 13. As shown in (B) of fig. 13, the electronic device may display a notification window in which the first prompt information is displayed. The first prompt message is that the SIM card is damaged and the SIM card is required to be replaced.

It should be understood that the above-mentioned manner in which the electronic apparatus displays the first prompt message may also be other contents, for example, the first prompt message may be used to indicate that the USIM card application is abnormal (for example, "USIM card application in SIM card is damaged"), or may also be used to indicate that the CSIM card application is abnormal (for example, "CSIM card application in SIM card is damaged"), which is merely by way of example and is not limited.

It should be noted that, the execution sequence of step S105 is after step S101, but the precedence relationship with other steps (S102, S103, and S104) may not be limited.

When the electronic device has completed the above operation, the user interface displayed by the electronic device may change to (c) in fig. 5A or (e) in fig. 5B. At this time, when the card status of the SIM card is normal, the application of the application layer of the electronic device may use services such as telephone, short message, data traffic, and the like. Therefore, when one card application of the dual-mode card goes wrong, some basic functions of the mobile phone can still be used, the robustness of the SIM card can be improved, and the user experience is better.

In the above process, when the first card application is the CSIM, the electronic device closes the CSIM, and at this time, the electronic device may use services of a telephone, a short message, and a data network through the USIM. When the first card application is a USIM, the electronic equipment closes the USIM, and at the moment, the electronic equipment can use the services of a telephone, a short message and a data network through the CSIM. Since USIM can cover 2G-5G (3 GPP standard included by USIM is GSM, WCDMA, LTE, NR), while CSIM can only use 2G and 3G (3 GPP2 standard included by CSIM is CDMA, CDMA2000), in SIM used by user, when CISM is damaged or lost, experience of electronic device using USIM is better, but when UISM is damaged or lost, experience of electronic device using CSIM is worse.

As used in the above embodiments, the term "when …" may be interpreted to mean "if …" or "after …" or "in response to determination …" or "in response to detection …", depending on the context. Similarly, depending on the context, the phrase "at the time of determination …" or "if (a stated condition or event) is detected" may be interpreted to mean "if the determination …" or "in response to the determination …" or "upon detection (a stated condition or event)" or "in response to detection (a stated condition or event)".
