Description

Technical Field

[0001] This application relates to the field of communication technology, specifically to a SIM card switching method, apparatus, terminal device, and storage medium. Background Technology

[0002] In the field of SIM card management for mobile communication terminals, the currently widely used dual-SIM dual-standby technology enables mobile phones to actively maintain the connection of two SIM cards simultaneously, but its card slot configuration mode has obvious limitations. Currently, the mainstream solutions mainly adopt two fixed combinations: one is equipped with two physical SIM card slots, requiring users to insert physical SIM cards to achieve dual-SIM standby; the other is a combination of one physical card slot and an eSIM, where the eSIM acts as a virtual SIM card to provide additional communication capabilities.

[0003] Taking eSIM-enabled devices as an example, although eSIM technology has advantages such as rewritability and flexible carrier switching, the existing technical framework still binds it to the physical SIM card slot in a fixed combination. For example, in dual-SIM phones, even if a user has stored information for multiple eSIM cards, they can only switch between the bound physical SIM card and a single eSIM card.

[0004] In this situation, users need to expand communication capabilities by increasing the number of physical card slots, which directly increases hardware costs and terminal size. The flexibility of eSIM technology is not fully utilized, and the multi-eSIM card storage function is rendered useless. Summary of the Invention

[0012] In some embodiments of this application, the method further includes: In response to the operation of selecting the first SIM card among multiple candidate SIM cards, a prompt message is displayed to guide you to set up call forwarding; In response to the prompt message's selection action, the user is redirected to the call forwarding settings interface to configure call forwarding functionality for the second SIM card.

[0013] Secondly, embodiments of the present invention also provide a SIM card switching device, comprising: The display module is used to display multiple candidate SIM cards corresponding to the target card slot. The multiple candidate SIM cards include the physical SIM card inserted into the terminal and the eSIM card supported by the terminal. The switching module is used to modify the modem's configuration parameters in response to the operation of selecting the first SIM card among multiple candidate SIM cards, so as to switch the SIM card currently bound to the target card slot from the second SIM card to the first SIM card.

[0014] Thirdly, this application also provides a terminal device, which includes: One or more processors; Memory; and One or more applications, wherein the applications are stored in memory and configured to be executed by a processor to implement the SIM card switching method of any of the first aspects.

[0015] Fourthly, embodiments of this application provide a computer-readable storage medium having a computer program stored thereon, the computer program being loaded by a processor to perform the steps in the SIM card switching method of any of the first aspects.

[0023] This application provides a SIM card switching method, apparatus, terminal device, and storage medium, which will be described in detail below.

[0024] Please see Figure 1 , Figure 1 This is a schematic diagram of a SIM card switching system provided in an embodiment of this application. The SIM card switching system may include a terminal device 100, which integrates a SIM card switching device, such as... Figure 1 Terminal devices in the process.

[0025] In this embodiment, the terminal device 100 is mainly used to display information of multiple candidate SIM cards corresponding to the target card slot. The multiple candidate SIM cards include physical SIM cards and eSIM cards supported by the terminal. In response to the operation of selecting the first SIM card among the multiple candidate SIM cards, the configuration parameters of the modem are modified to switch the SIM card currently bound to the target card slot from the second SIM card to the first SIM card. This allows the user to freely switch the SIM card bound to the card slot in the terminal, achieving a function similar to multi-SIM card standby with fewer card slots, significantly reducing costs and energy consumption, and improving the user experience.

Specifically, the terminal device 100 may be a desktop terminal or a mobile terminal, and the terminal device 100 may also be one of a mobile phone, tablet computer, laptop computer, etc.

[0028] Those skilled in the art will understand that Figure 1 The application environment shown is merely one application scenario of the solution in this application and does not constitute a limitation on the application scenario of the solution in this application. Other application environments may include those that are more specific to this application. Figure 1 The number of more or fewer terminal devices shown, for example Figure 1 Only one terminal device is shown in the diagram. It is understood that the SIM card switching system may also include one or more other services, which are not specified here.

[0029] In addition, such as Figure 1 As shown, the SIM card switching system may also include a memory 200 for storing data, such as information on multiple candidate SIM cards, configuration parameters, etc.

[0030] It should be noted that, Figure 1 The schematic diagram of the SIM card switching system shown is merely an example. The SIM card switching system and scenario described in this application are for the purpose of more clearly illustrating the technical solutions of this application and do not constitute a limitation on the technical solutions provided in this application. As those skilled in the art will know, with the evolution of SIM card switching systems and the emergence of new business scenarios, the technical solutions provided in this application are also applicable to similar technical problems.

[0031] First, this application provides a SIM card switching method. The execution subject of the SIM card switching method is a SIM card switching device, which is applied to a terminal device. The SIM card switching method includes: displaying information of multiple candidate SIM cards corresponding to a target SIM card slot, wherein the multiple candidate SIM cards include physical SIM cards and eSIM cards supported by the terminal; in response to the operation of selecting a first SIM card among the multiple candidate SIM cards, modifying the configuration parameters of the modem to switch the SIM card currently bound to the target SIM card slot from a second SIM card to the first SIM card.

[0032] In related technologies, although the chips in mobile phones and other terminal devices (using mobile phones as an example below) have the ability to support writing information for multiple eSIM cards, allowing the terminal device to store configuration data for multiple eSIM cards, in practical applications, mobile phone manufacturers are limited by multiple factors such as hardware design, cost control, and user experience, and generally adopt a dual-SIM dual-standby architecture as the mainstream solution. Under this architecture, mobile phones are usually equipped with only two physical card slots, or a combination of one physical card slot and one eSIM card slot, resulting in the terminal device being able to realize the standby function of a maximum of two SIM cards at any given time.

[0033] Specifically, when a user needs to switch communication cards, the system only allows switching between the SIM cards corresponding to the two bound card slots. For example, between the physical SIM card (PSIM card) in physical card slot 1 and the physical SIM card in physical card slot 2, or between the physical SIM card and the eSIM card in the physical card slot, the user can only choose the activation target. The system cannot break through the limitation of the number of card slots.

[0034] For example, in phones that support eSIM functionality, although the chip level supports the storage and management of multiple eSIM cards, in actual use, users still need to pre-bind a certain eSIM card to the physical card slot or the built-in eSIM card slot to form a fixed dual-SIM combination. This leads to the following problems: First, if a user needs to use a third SIM card, they must switch by turning off the phone and inserting / removing the physical card, which is cumbersome and inefficient. Second, the multi-eSIM card storage function is rendered useless, as users cannot dynamically adjust the active SIM card according to actual needs (such as cross-regional roaming or tariff optimization), resulting in wasted resources. Third, there is hardware design redundancy; if phone manufacturers need to add card slots or independent eSIM modules to support multi-SIM functionality, it will increase the cost and size of the terminal, which contradicts the trend of thinner and lighter mobile devices.

[0035] In other words, although current hardware technology supports multiple eSIM cards, it is limited by the hardware framework of dual SIM dual standby and static binding logic, which fails to unleash the full value of eSIM technology, resulting in significant problems for users in terms of multi-card management, cost optimization and energy efficiency control.

[0036] To solve the above problems, such as Figure 2 The diagram shown is a flowchart of an embodiment of the SIM card switching method in this application. The SIM card switching method may include the following steps S201 to S202, as detailed below: Step S201: Display information on multiple candidate SIM cards corresponding to the target card slot, including physical SIM cards and eSIM cards supported by the terminal.

[0037] In one specific embodiment, this application can be applied to terminal devices, specifically mobile devices based on SIM card communication such as mobile phones, tablets, and smartwatches, or communication devices in the Internet of Things (IoT) field that have SIM cards installed. It should be noted that the SIM card in this application includes both physical SIM cards (PSIM cards) and eSIM cards. The execution entity of this step can be the control system in the terminal device, which can switch SIM cards based on user operations on the terminal device. User operations on the terminal device can take various forms, such as button operations, click operations, gesture operations, etc., and this embodiment does not limit the specific methods.

[0038] The target SIM card slot can be a pre-set physical SIM card slot in the terminal device, capable of inserting a physical SIM card, or it can be an embedded SIM card chip that can be bound to an eSIM card via over-the-air (OTA) writing. To some extent, the target SIM card slot can be understood as an empty slot for a SIM card waiting to be powered on; the powered-on SIM card can be a physical SIM card or an eSIM card. Multiple candidate SIM cards include all available SIM cards stored in the phone's chip, including physical SIM cards and written eSIM cards, such as physical SIM card A, eSIM card B, and eSIM card C inserted into the user's phone. The information for the multiple candidate SIM cards can be information indicating the identity of the corresponding SIM card, such as the SIM card identifier, the corresponding operator, or the corresponding phone number; this embodiment does not impose such limitations.

[0039] In this embodiment, the terminal system can provide the user with all SIM card options that can be bound to the current target card slot through a display interface, allowing the user to intuitively understand the available resources. Specifically, a list of candidate SIM cards can be displayed through the user interface (UI), including information on multiple candidate SIM cards, so that the user can distinguish between multiple candidate SIM cards and avoid operational errors due to missing information. For example, it can display "eSIM-operator A-155xxxxxxxx" or "PSIM-operator B-188xxxxxxxx", but this embodiment is not limited to this.

[0040] Step S202: In response to the operation of selecting the first SIM card among multiple candidate SIM cards, modify the configuration parameters of the modem to switch the SIM card currently bound to the target card slot from the second SIM card to the first SIM card.

[0041] The first SIM card can be the SIM card selected by the user through the UI interface and bound to the target SIM card slot. The modem is the core component of the baseband chip, responsible for handling mobile communication signal protocols and data. Configuration parameters include SIM card type (PSIM / eSIM), the identifier of the SIM card to be powered on, network protocol, communication bandwidth, etc., which can be dynamically modified through the software interface. The second SIM card refers to the original SIM card bound to the target SIM card slot before the switch; it can be a PSIM or eSIM.

[0042] In one specific embodiment, the user selects the SIM card to be bound from a candidate list via a UI interface. Specific operations may include user input behaviors such as clicking and swiping. The system can capture the user's intention to actively select the card, converting the user's request into an executable command, triggering the SIM card switching process to switch the currently bound SIM card in the target slot from the previous second SIM card to the user-selected first SIM card. Through intuitive interactive design, the system lowers the user's operational threshold, improves switching efficiency, and allows users to flexibly adjust SIM card binding according to actual needs (such as roaming or tariff changes), enhancing adaptability to various usage scenarios. In this embodiment, by responding to user operations, the modem parameters are dynamically modified, enabling the target card slot to switch from a SIM card at the software level. This is equivalent to supporting a function similar to switching between multiple SIM cards under the current dual-SIM architecture, without the need for additional hardware modules, significantly reducing costs and energy consumption, and improving the user experience.

[0043] In one specific implementation, in response to the operation of selecting a first SIM card from multiple candidate SIM cards, the configuration parameters of the modem are modified, including: in response to the operation of selecting a first SIM card from multiple candidate SIM cards, generating switching information, wherein the switching information includes the identifier of the first SIM card; sending the switching information to the application framework layer through the application framework interface, wherein the application framework layer generates a parameter modification instruction based on the switching information, and calls the modem's interface to send the parameter modification instruction to the modem, so that the modem modifies the configuration parameters based on the parameter modification instruction.

[0044] In this embodiment, the switching information can be a data packet containing the unique identifier of the first SIM card, used to instruct the system to perform a switching operation. After the user makes a selection, the system captures the user's intent and generates switching information to drive various modules in the terminal device to perform relevant operations, thereby realizing the SIM card switching. The application framework layer is the middle layer in the Android system architecture, responsible for parsing user commands and calling the underlying hardware interfaces. The application framework interface refers to the Android Framework API, used for interaction between upper-layer applications (such as the settings interface) and the underlying system (application framework layer).

[0045] When a user selects a SIM card from multiple candidate SIM cards in the phone's UI as the primary SIM card—for example, switching the binding of SIM slot 2 from a physical SIM card to an eSIM card—Carrier A—the system generates a switching message containing the unique identifier of the primary SIM card. This message serves as the basis for subsequent operations. This switching message is passed to the application framework layer through the phone's operating system's application framework interface, where the user's intent is parsed and converted into executable system commands. Based on the primary SIM card identifier in the switching message, the application framework layer generates specific parameter modification commands, such as "change the binding of SIM slot 2 to an eSIM card—Carrier A," and sends these commands to the modem by calling the modem's underlying interface. Upon receiving the commands, the modem modifies its internal configuration parameters, such as SIM slot power control and communication protocol stack configuration, to power on the primary SIM card and complete network registration, thus achieving dynamic switching between the SIM slot and SIM card type.

[0046] In one specific implementation, the switching information is sent to the application framework layer through the application framework interface. The application framework layer generates a parameter modification instruction based on the switching information and calls the modem's interface to send the parameter modification instruction to the modem. This includes: sending the switching information to the application framework layer through the application framework interface; the application framework layer performing permission verification and obtaining the verification result; if the verification result indicates that the permission verification is successful, the application framework layer generates a parameter modification instruction based on the switching information and calls the modem's interface to send the parameter modification instruction to the modem.

[0047] In this embodiment, the application framework layer can also perform user permission verification before sending instructions to ensure security. Permission verification can specifically be user authentication (such as password or fingerprint) or operation permission checks (such as administrator privileges) to prevent network configuration chaos or security risks caused by unauthorized switching.

[0048] When a user initiates a SIM card switching operation on the phone interface, the system first generates switching information containing the identifier of the first SIM card. This information is passed to the application framework layer through the application framework interface of the phone's operating system. In the application framework layer, the system executes a permission verification process, checking whether the current operation meets preset security conditions, such as allowing only administrator accounts or the phone owner to switch, and returns a verification result (pass / reject). If the verification passes, the application framework layer generates specific parameter modification instructions based on the first SIM card identifier in the switching information, and then calls the modem's underlying driver interface to send the instructions to the modem. After receiving the instructions, the modem modifies its internal configuration parameters, powering on the first SIM card and completing network registration, ultimately achieving dynamic switching between the card slot and the SIM card type.

[0049] If the verification fails, the system can immediately terminate the generation and issuance of parameter modification commands to prevent Modom from receiving illegal configuration requests. Additionally, a pop-up message can be displayed in the user interface, clearly informing the user that "You do not have permission to perform this operation. Please log in using an administrator account." The illegal operation can also be recorded in the system security log (including time, user ID, and first SIM card identifier) ​​for administrator auditing or tracing.

[0050] This embodiment ensures that the SIM card dynamic switching function only takes effect in legal scenarios, which meets the core requirements for improving system security and provides mobile phone manufacturers with a feasible security control solution.

[0051] In one specific implementation, in response to the operation of selecting a first SIM card among multiple candidate SIM cards, after modifying the configuration parameters of the modem, the process includes: restarting the terminal to power on the first SIM card via the modem based on the modified configuration parameters.

[0052] In this embodiment, since the modification of the modem parameters usually requires a restart and re-initialization of the hardware module (such as the card slot controller) to ensure that the new configuration is loaded correctly; in addition, after the SIM card is switched, the modem needs to re-establish a connection with the operator's network (such as attaching to the LTE core network). A restart can trigger a complete network registration process and avoid communication abnormalities caused by parameters not being refreshed.

[0053] Therefore, after modifying the modem's configuration parameters, the system needs to restart the terminal so that the modem reloads the configuration parameters during the restart process and performs a power-on operation on the first SIM card according to the modified new configuration parameters. That is, the power-on program of the start card chip is controlled by the chip parameters to finally complete network registration and realize the switching of SIM cards without the need for hardware insertion and removal.

[0054] In one specific implementation, displaying multiple candidate SIM cards corresponding to the target SIM card slot includes: displaying SIM card switching settings options; displaying target SIM card slot settings options in response to selecting the SIM card switching settings option; and displaying information about multiple candidate SIM cards in a drop-down menu in response to selecting the target SIM card slot settings option.

[0055] In this embodiment, a "SIM card switching settings" option can be added to the phone's settings interface as an entry point for SIM card switching. If the user clicks this option, a new SIM card management interface will display the "target card slot settings" option, such as "card slot 1 settings" and "card slot 2 settings." These two options allow control over the SIM cards bound to the two card slots in a dual-SIM phone. The user can select the desired card slot and perform targeted operations. After the user selects a card slot (e.g., card slot 2), the system can read the written eSIM card information (e.g., IMSI, carrier identifier) ​​and physical SIM card status (e.g., whether it is inserted) from the modem, dynamically generating a list containing information on all candidate SIM cards. Specifically, the UI interface can display all SIM cards that can be bound to the card slot in the form of a drop-down menu, from which the user can select the first SIM card. It should be noted that, besides the drop-down menu, there can be other ways to display information on multiple candidate SIM cards; this embodiment does not impose any limitations.

[0056] In one specific implementation, the method further includes: in response to the operation of selecting a first SIM card from a plurality of candidate SIM cards, displaying the association between the target card slot and the first SIM card, and / or, displaying the operator information of the first SIM card.

[0057] In this embodiment, when a user selects one of multiple candidate SIM cards as the first SIM card in the mobile phone SIM card management interface, for example, selecting eSIM card - operator A, the system will obtain the detailed information of the first SIM card and bind it to the target card slot. Then, the binding result can be rendered to the screen through the UI interface, immediately displaying the association between the target card slot and the first SIM card (e.g., "Card Slot 2: eSIM - operator - A"). At the same time, the operator information of the first SIM card can be selectively displayed, such as operator name, communication number (mobile phone number), network standard, or tariff plan.

[0058] In one specific implementation, the method further includes: in response to the operation of selecting a first SIM card among multiple candidate SIM cards, displaying a prompt message for prompting the setting of call forwarding; and in response to the selection operation of the prompt message, jumping to the call forwarding setting interface to set the call forwarding function for the second SIM card through the call forwarding setting interface.

[0059] In this embodiment, the user wants to switch to the first SIM card. After the switch, the first SIM card will replace the second SIM card in the original card slot to perform the communication function. In order to facilitate the user, the system can provide a call forwarding setting entry for the card to avoid the second SIM card being unable to answer calls after the switch, which would cause service interruption.

[0060] When a user selects the first SIM card in the phone's SIM card management interface, the system can display a prompt message to help set up call forwarding, such as a pop-up window asking, "Switching SIM cards may cause the original number to be unable to receive calls. Do you want to set up call forwarding?"

[0061] If the user chooses to trigger this prompt, such as clicking "Yes", the system will redirect to the call forwarding settings interface. In this interface, the user can configure call forwarding rules for the second SIM card, such as forwarding all incoming calls to the newly switched eSIM card - Operator A or other designated numbers.

[0062] As one specific implementation method, such as Figure 3 As shown, taking SIM slot 2 in a dual-SIM phone as an example, after the user starts the phone, the system reads the current configuration parameters of the modem and binds SIM slot 2 to the corresponding default SIM card (i.e., the second SIM card mentioned earlier). The user can reset the SIM card by entering the settings interface and selecting the physical SIM card or eSIM card (i.e., the first SIM card mentioned earlier) to be bound to SIM slot 2. The system can then modify the modem's configuration parameters by calling the Modem API through the application framework layer, and then restart the phone. A prompt message can also appear asking the user whether to set call forwarding for the original default SIM card. If the user selects "yes," the system will jump to the call forwarding module for settings; otherwise, it will directly restart the phone. After restarting, the phone will reload the configuration parameters, power on the selected SIM card according to the new configuration parameters, and complete the initialization, realizing the dual-SIM dual-standby function. In addition, the system can periodically shut down unused eSIM cards in the background to avoid energy waste.

[0063] To better implement the SIM card switching method in the embodiments of this application, based on the SIM card switching method, the embodiments of this application also provide a SIM card switching device, such as... Figure 4 As shown, the SIM card switching device 400 includes: Display module 410 is used to display multiple candidate SIM cards corresponding to the target card slot, wherein the multiple candidate SIM cards include the physical SIM card inserted into the terminal and the eSIM card supported by the terminal; The switching module 420 is used to modify the configuration parameters of the modem in response to the operation of selecting a first SIM card among multiple candidate SIM cards, so as to switch the SIM card currently bound to the target card slot from the second SIM card to the first SIM card.

[0064] In this embodiment, by displaying information about multiple candidate SIM cards corresponding to the target SIM card slot to the user, and after the user selects the first SIM card from the multiple candidate SIM cards, the configuration parameters of the modem are modified to switch the SIM card bound to the target SIM card slot from the second SIM card to the first SIM card. This allows the user to freely switch the SIM card bound to the SIM card slot in the terminal, achieving a function similar to multi-SIM card standby with fewer SIM card slots, significantly reducing costs and energy consumption, and improving the user experience.

[0065] In some embodiments of this application, the switching module 420, in response to the operation of selecting a first SIM card among a plurality of candidate SIM cards, modifies the configuration parameters of the modem, including: In response to the operation of selecting a first SIM card among multiple candidate SIM cards, handover information is generated, wherein the handover information includes the identifier of the first SIM card; The switching information is sent to the application framework layer through the application framework interface. The application framework layer generates parameter modification instructions based on the switching information and calls the modem's interface to send the parameter modification instructions to the modem, so that the modem can modify the configuration parameters based on the parameter modification instructions.

[0066] In some embodiments of this application, the switching module 420 sends switching information to the application framework layer through the application framework interface. The application framework layer generates parameter modification instructions based on the switching information and calls the modem's interface to send the parameter modification instructions to the modem, including: The switching information is sent to the application framework layer via the application framework interface; The application framework layer performs permission verification and obtains the verification result. If the verification result shows that the permission verification is successful, the application framework layer generates a parameter modification instruction based on the switching information and calls the modem's interface to send the parameter modification instruction to the modem.
