[0002] A SIM (Subscriber Identity Module) card is a smart card used in mobile terminals. It enables users to connect to cellular mobile networks and use services such as voice, SMS, and mobile data.

[0003] With the increasing popularity of dual SIM cards and virtual SIM cards, users may frequently change their SIM cards or SIM card slot positions, which can easily lead to the inability of the terminal to use network services.

Attached Figure Description

[0021] To more clearly illustrate the technical solutions in this application, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0022] Figure 1 This is a schematic diagram of the steps of a smart card management method provided in an embodiment of this application; Figure 2 This is a schematic diagram of the structure of a smart card management device provided in an embodiment of this application; Figure 3 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application. Detailed Implementation

[0023] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] It should be noted that the SIM card is used to securely store the IMSI (International Mobile Subscriber Identity) and is used for customer authentication on the GSM (Global System for Mobile Communications) network. It enables users to connect to the cellular mobile network and use services such as voice, SMS, and mobile data.

[0025] Currently, some devices also feature a virtual SIM card (also known as an eSIM or embedded SIM card). This virtual SIM card isn't a physical plastic card, but rather a chip soldered directly onto the phone's motherboard. A single virtual SIM chip can store multiple configuration files from different carriers, allowing users to switch between them as needed, thus enabling them to switch carriers without changing their physical SIM card.

[0026] Currently, the activation and identification mechanism of carrier networks typically works as follows: When a user inserts a SIM card for the first time (whether a physical card or a virtual SIM card configuration file) and attempts to access the internet, the phone registers with the carrier network. During registration, the phone reports the terminal's IMEI number and the SIM card's identification information to the carrier's server. The carrier's server then binds and records the SIM card with this IMEI number. This binding relationship indicates that the user (SIM card) is using this specific phone (IMEI). Subsequently, each time the phone accesses the internet, the carrier network verifies whether the current device's IMEI and SIM card match the previously bound record. If they match, internet access is granted; if they do not match, the carrier considers it an anomaly (e.g., the user has changed their phone, the SIM card has been stolen, or the phone has been stolen), triggering a security mechanism that may result in network access being denied, requiring the user to reactivate and authenticate.

[0027] Current dual-SIM dual-standby phones typically have two IMEI numbers (e.g., IMEI1 and IMEI2), corresponding to SIM card slot 1 and SIM card slot 2 respectively. When users frequently change SIM cards or SIM card slot positions, the terminal operator needs to reactivate the binding relationship between the SIM card and the IMEI.

[0028] In one example, a user inserts SIM card A into SIM slot 1 to access the internet. The carrier records that SIM card A is bound to IMEI1. The user then removes SIM card A from SIM slot 1 and inserts it into SIM slot 2. When the user uses SIM slot 2 to access the internet, the phone reports SIM card A + IMEI2 to the network. The carrier verifies this and finds that the previous record indicated SIM card A was bound to IMEI1, but the current record shows SIM card A bound to IMEI2. This mismatch is considered abnormal and may result in internet access failure. The user is then required to contact customer service for re-verification and activation.

[0029] In another example, a user uses physical SIM card A to access the internet in SIM card slot 1. The operator records that physical SIM card A is bound to IMEI1. The user then disables physical SIM card A and activates virtual SIM card B in the phone. When the phone uses virtual SIM card B to access the internet, it reports virtual SIM card B + IMEI1 to the network. The operator verifies this and finds that this IMEI1 was previously bound to physical SIM card A, but now it appears together with virtual SIM card B, indicating a mismatch in the binding relationship. This triggers the security mechanism again, requiring the operator to reactivate the SIM card.

[0030] To address the issue that current binding mechanisms cannot adapt to dynamic multi-SIM usage scenarios arising from multiple SIM card slot changes and virtual SIM card switching, this application aims to provide a smart card management method. This method, in response to a first smart card insertion event into a terminal, acquires the terminal's smart card binding information and smart card status information. Based on these information, it determines the target device identification code and binds it to the first smart card. This automatically matches a suitable target device identification code to the inserted smart card, ensuring successful network connectivity for the terminal while allowing operators to complete activation without needing to inquire about the smart card type and slot information. This reduces operator operating costs and improves user experience.

[0031] The following sections provide detailed descriptions of each example. It should be noted that the order in which the embodiments are described is not intended to limit the priority of the embodiments.

[0032] Figure 1 A flowchart illustrating a smart card management method according to an embodiment of this application is shown. The entity executing the smart card management method may be a smart card management device, which may be integrated into an electronic device configured with a smart card. The electronic device may be a smartphone, smartwatch, tablet, laptop, in-vehicle device, Internet of Things (IoT) device, smart home device, etc., but is not limited thereto.

[0033] The following sections provide detailed descriptions of each example. It should be noted that the order in which the embodiments are described is not intended to limit the preferred order of the embodiments.

[0034] In this embodiment, the description will be from the perspective of a smart card management device, which can be integrated into a terminal. To facilitate the explanation of the smart card management method of this application, the following will describe it in detail with the smart card management device integrated into the terminal, that is, with the terminal as the execution subject.

[0035] Reference Figure 1 This application illustrates a smart card management method, which may specifically include the following steps: S101: In response to the insertion event of the first smart card being inserted into the terminal, obtain the smart card binding information and smart card status information of the terminal.

[0036] In this embodiment, the smart card binding information represents the correspondence between the smart cards bound to the terminal and the device identification codes. The smart card can be a SIM card, which can be a physical SIM card or a virtual SIM card (eSIM). The device identification code represents the terminal's unique identifier, specifically an IMEI. When the terminal is bound to multiple smart cards, the smart card binding information specifically represents the one-to-one correspondence between the multiple bound SIM cards and multiple IMEIs.

[0037] In this embodiment, each time the terminal matches the corresponding device identification code for an inserted smart card, it records the correspondence between the smart card and the device identification code in the smart card binding information. For example, when the terminal is a dual-SIM dual-standby terminal, the terminal can assign IMEI1 to SIM card A and IMEI2 to SIM card B. Then, the smart card binding information includes the correspondence between SIM card A and IMEI1, as well as the correspondence between SIM card B and IMEI2.

[0038] In this embodiment, the smart card in the smart card binding information can be represented by a smart card identifier. Specifically, this smart card identifier can be an ICCID (Integrated Circuit Card Identity). For example, Table 1 shows an example table of smart card binding information.

[0039] Table 1. Example of Smart Card Binding Information

[0040] In this embodiment, the smart card status information indicates whether the terminal has a second smart card besides the first smart card. The first smart card refers to the smart card currently inserted into the terminal, and the second smart card refers to one or more smart cards inserted into the terminal before the first smart card. The first smart card can be a physical SIM card or a virtual SIM card, and the second smart card can be a physical SIM card and / or a virtual SIM card.

[0041] In this embodiment, after the terminal detects the insertion event of the first smart card into the terminal, it will trigger smart card detection to determine whether there is a second smart card other than the first smart card, and then determine the smart card status information based on the detection result.

[0042] In this embodiment, for any card slot other than the slot corresponding to the first smart card, the status information of the card slot pins can be detected by a baseband chip or a dedicated SIM interface controller to determine whether a smart card is present in the slot. It should be noted that each physical SIM card slot has specific detection pins. When a SIM card is inserted into the slot, the gold fingers on the SIM card contact the detection pins of the slot, thereby changing the electrical state of the detection pins, such as a level flip. By detecting the electrical state, the presence of a SIM card in the slot can be accurately determined.

[0043] In this embodiment, the activation status of a virtual SIM card can be determined through power supply and communication protocols. Specifically, the operating system can send a test command to the eSIM chip based on the communication protocol. If a response is received from the eSIM chip in response to the test command, the eSIM is confirmed to exist and function normally; if no response is received, the virtual SIM card is confirmed to be faulty or non-existent.

[0044] S102: Based on the smart card binding information and smart card status information, determine the target device identification code and bind the target device identification code to the first smart card.

[0045] In this embodiment, by analyzing the smart card binding information and smart card status information, it is possible to effectively determine whether a second smart card has already occupied the corresponding device identification code. Then, based on the smart card binding information, a suitable target device identification code is assigned to the first smart card, and the first smart card is bound to the target device identification code.

[0046] In this implementation, by assigning and matching a device identification code to each smart card within the terminal, it is ensured that each smart card can always match the corresponding target device identification code, regardless of the card slot location or the type of virtual / physical card. On the one hand, for users, they can freely change the smart card location or use a virtual card without worrying about network registration failures or the need for reactivation, making it more convenient and greatly improving the user experience. On the other hand, for operators, the binding relationship they receive is always stable and consistent, and activation can be completed without inquiring about the smart card type and card slot information, thereby effectively simplifying the operator's operating costs and reducing unnecessary work.

[0047] In one feasible implementation, the step of determining the target device identification code based on smart card binding information and smart card status information may specifically include the following sub-steps: S102-1: Determine the type information of the first smart card based on the smart card binding information.

[0048] In this embodiment, the type information indicates whether the first smart card is a new smart card. A new smart card indicates that there is no smart card listed in the smart card binding information.

[0049] In the specific implementation, the terminal reads the ICCID of the first smart card inserted through the baseband chip, and then queries the smart card binding information based on the ICCID. If the same ICCID is found, the type information of the first smart card is determined to be the first type information, which indicates that the first smart card is not a new smart card; if the same ICCID is not found, the type information of the first smart card is determined to be the second type information, which indicates that the first smart card is not a new smart card.

[0050] In this embodiment, to ensure security and privacy protection, the terminal can use an encrypted hash function (such as SHA-256) to process the ICCID, generating a unique and irreversible hash value. Even if someone illegally obtains the smart card binding information, they will not be able to deduce the original ICCID number, thus protecting user privacy. At this point, the terminal can generate the hash value corresponding to the ICCID of the first smart card and match it with the hash values ​​corresponding to the ICCIDs of each smart card already bound in the smart card binding information to determine the type information of the first smart card.

[0051] S102-2: Determine the target device identification code based on type information, smart card binding information, and smart card status information.

[0052] In this embodiment, since different type information and / or different smart card status information contain various types of smart card insertion events, by further considering the type information of the first smart card based on the smart card binding information and smart card status information, it is possible to quickly assign a suitable target device identification code to the first smart card in various smart card insertion scenarios.

[0053] In one feasible implementation, the step of determining the target device identification code based on type information, smart card binding information, and smart card status information may specifically include the following sub-steps: S102-2-A: When the type information indicates that the first smart card is not a new smart card and the smart card status information indicates that the terminal has a second smart card, extract the first binding information corresponding to the first smart card and the second binding information corresponding to the second smart card from the smart card binding information, and determine the target device identification code based on the first binding information and the second binding information.

[0054] In this embodiment, when it is detected that the first smart card is not a new smart card and the terminal has a second smart card, it indicates that the first smart card is an old card and its binding relationship may conflict with that of the second smart card. In this case, the first binding information corresponding to the first smart card and the second binding information corresponding to the second smart card will be extracted from the smart card binding information, and a suitable target device identification code will be matched for the first smart card based on the first binding information and the second binding information.

[0055] In a specific implementation, the step of determining the target device identification code based on the first binding information and the second binding information may include: determining the first device identification code corresponding to the first smart card based on the first binding information, and determining the second device identification code corresponding to the second smart card based on the second binding information; if the first device identification code and the second device identification code are inconsistent, determining the first device identification code as the target device identification code; if the first device identification code and the second device identification code are consistent, determining the target device identification code from the remaining device identification codes of the terminal.

[0056] In this embodiment, the remaining device identification code refers to the remaining device identification code in the terminal. The remaining device identification code can be a physical SIM card and / or a virtual SIM card in the terminal that is not bound to the second smart card.

[0057] In this embodiment, if the first device identification code and the second device identification code are found to be inconsistent, that is, there is no device identification code conflict between the first smart card and the second smart card, the first device identification code originally bound to the first smart card will continue to be used; if the first device identification code and the second device identification code are found to be consistent, that is, there is a device identification code conflict between the first smart card and the second smart card, a new target device identification code will be matched for the first smart card to ensure the normal use of the second smart card.

[0058] In this embodiment, by analyzing the first binding information and the second binding information, the normal use of the terminal can be ensured, while effectively avoiding conflicts between the first smart card (which is the old card) and the inserted second smart card.

[0059] In this embodiment, considering that the binding relationship of the first smart card in the smart card binding information will change after the device identification code of the first smart card is reassigned, if the first device identification code and the second device identification code are the same, after determining the target device identification code from the remaining device identification codes of the terminal, the smart card management method may further include: updating the device identification code corresponding to the first smart card from the first device identification code to the target device identification code in the smart card binding information.

[0060] In this embodiment, in the event that the binding relationship of the first smart card in the smart card binding information may change, the device identification code corresponding to the first smart card is updated from the first device identification code to the target device identification code in a timely manner. This ensures that the accuracy of the smart card binding information is always maintained, thereby ensuring that the allocation of device identification code resources is always orderly and that multiple smart cards do not compete for the same device identification code without their knowledge, which would lead to network authentication failure.

[0061] S102-2-B: When the type information indicates that the first smart card is not a new smart card and the smart card status information indicates that the terminal does not have a second smart card, the device identification code corresponding to the first smart card in the smart card binding information is determined as the target device identification code.

[0062] In this embodiment, when it is detected that the first smart card is not a new smart card and the terminal does not have a second smart card, it indicates that the first smart card is an old card, and there is no situation where the second smart card occupies the device identification code corresponding to the first smart card. At this time, the device identification code corresponding to the first smart card in the smart card binding information can be directly determined as the target device identification code.

[0063] S102-2-C: When the type information indicates that the first smart card is a new smart card and the smart card status information indicates that the terminal has a second smart card, the target device identification code is determined from the remaining device identification codes of the terminal.

[0064] In this embodiment, when a new smart card is detected and a second smart card exists in the terminal, it indicates that the first smart card is a new card, and the smart card binding information does not contain a device identification code corresponding to the first smart card. In this case, to avoid conflict with the second smart card, the target device identification code will be determined from the remaining device identification codes in the terminal.

[0065] S102-2-D: When the type information indicates that the first smart card is a new smart card and the smart card status information indicates that the terminal does not have a second smart card, the terminal's preset device identification code is determined as the target device identification code.

[0066] In this embodiment, when a new smart card is detected and the terminal does not have a second smart card, it indicates that the first smart card is a new card, the smart card binding information does not contain a device identification code corresponding to the first smart card, and there is no situation where a second smart card occupies a device identification code. In this case, a preset device identification code can be directly determined as the target device identification code. Here, the preset device identification code represents the terminal's default device identification code; for example, the terminal's IMEI1 can be defined as the preset device identification code.

[0067] In this embodiment, under four smart card insertion scenarios corresponding to different types of information and different smart card status information, the first smart card and the target device identification code can be intelligently bound according to the smart card binding information. While ensuring terminal availability, this effectively avoids device identification code conflicts and ensures that no matter how many times the same smart card is inserted or removed, as long as it is used on the terminal, the terminal will assign it a suitable target device identification code, thus avoiding the operator from repeatedly activating the binding relationship between the smart card and the device identification code.

[0068] In this embodiment, to achieve timely updates to the smart card binding information, when the type information indicates that the first smart card is a new smart card and the smart card status information indicates that the terminal has a second smart card, the target device identification code is determined from the remaining device identification codes of the terminal; or when the type information indicates that the first smart card is a new smart card and the smart card status information indicates that the terminal does not have a second smart card, the terminal's preset device identification code is determined as the target device identification code. The smart card management method further includes adding the correspondence between the first smart card and the target device identification code to the smart card binding information.

[0069] In this embodiment, when the first smart card is inserted into the terminal as a new card, the correspondence between the first smart card and the target device identification code is added to the smart card binding information in a timely manner. This enables the timely updating of the smart card binding information and effectively ensures the accuracy of the allocation or switching of the device identification code that may appear again in the future.

[0070] In one example, the terminal is a dual-SIM dual-standby terminal. The user first inserts SIM card A into card slot 1. The terminal detects that SIM card A is a new card and that there is no other second smart card in card slot 2. The terminal will match the preset device identification code IMEI1 for SIM card A and record the correspondence between SIM card A and IMEI1 in the smart card binding information.

[0071] The user then inserts SIM card A into card slot 2. The terminal detects that SIM card A is not a new smart card and that the terminal does not have any other second smart cards (i.e., there are no other second smart cards in card slot 1). At this time, the IMEI1 corresponding to SIM card A in the smart card binding information is determined as the target device identification code, that is, IMEI1 continues to be used, and SIM card A will not be re-bound to IMEI2, thereby avoiding the operator from activating the binding relationship between SIM card A and IMEI2.

[0072] The user then inserts SIM card B into card slot 1. The terminal detects that SIM card B is a new smart card and that the terminal has a second smart card (i.e., SIM card A). At this time, the terminal will determine the remaining device identification code (i.e., IMEI2) as the target device identification code of SIM card B.

[0073] Subsequently, the user needs to swap the slot positions of SIM cards A and B, and remove SIM cards A and B. Then, SIM card A is inserted into slot 1. At this point, SIM card A continues to be bound to IMEI1. However, when the user inserts SIM card B into slot 2, an error occurs in the smart card binding information, causing SIM card B to be bound to IMEI1 in the smart card binding information. Upon detecting that SIM card B and SIM card A are identical, the terminal will bind the remaining device identification code (i.e., IMEI2) to SIM card B and update the IMEI corresponding to SIM card B from IMEI1 to IMEI2 in the smart card binding information. This not only avoids new conflicts but also automatically detects and corrects any previously erroneous binding records, ensuring that at any given time, one IMEI can only be used by one active SIM card, thus completely preventing the situation where two SIM cards correspond to one IMEI.

[0074] In this implementation, on the one hand, users no longer need to worry about their phones becoming unable to access the internet or needing to reactivate due to changing the physical SIM card slot. They can freely switch between primary and secondary SIM cards in any slot, with the system automatically handling IMEI adaptation and seamless network connectivity. Furthermore, when using virtual SIM cards such as eSIMs, the user experience is completely consistent with that of physical SIM cards. Switching between eSIM plans or numbers eliminates concerns about conflicts with the existing physical SIM card's binding, significantly improving the user experience. On the other hand, operators can complete activation without inquiring about the smart card type or slot information, fundamentally avoiding complaints and subsequent repair requests caused by users unintentionally changing SIM slots, thus significantly reducing the operator's operational and maintenance costs.

[0075] To facilitate better implementation of the smart card management method of this application, this application also provides a smart card management device based on the above-described smart card management method. The meanings of the terms used are the same as in the smart card management method described above, and specific implementation details can be found in the descriptions of the method embodiments.

[0076] Based on the same inventive concept, and referring to Figure 2 This application provides a smart card management device 200, which includes: The information acquisition module 201 is used to acquire the smart card binding information and smart card status information of the terminal in response to the insertion event of the first smart card; the smart card binding information represents the correspondence between the smart card bound to the terminal and the device identification code, and the smart card status information represents whether the terminal has a second smart card other than the first smart card; The identification code binding module 202 is used to determine the target device identification code based on the smart card binding information and smart card status information, and bind the target device identification code to the first smart card.

[0077] In one embodiment, the identification code binding module 202 includes: The type determination submodule is used to determine the type information of the first smart card based on the smart card binding information; the type information indicates whether the first smart card is a new smart card. The identification code determination submodule is used to determine the target device identification code based on type information, smart card binding information, and smart card status information.

[0078] In one embodiment, the identification code determination submodule includes: The first determining unit is used to extract the first binding information corresponding to the first smart card and the second binding information corresponding to the second smart card from the smart card binding information when the type information indicates that the first smart card is not a new smart card and the smart card status information indicates that the terminal has a second smart card, and to determine the target device identification code based on the first binding information and the second binding information. The second determining unit is used to determine the device identification code corresponding to the first smart card in the smart card binding information as the target device identification code when the type information indicates that the first smart card is not a new smart card and the smart card status information indicates that the terminal does not have a second smart card. The third determining unit is used to determine the target device identification code from the remaining device identification codes of the terminal when the type information indicates that the first smart card is a new smart card and the smart card status information indicates that the terminal has a second smart card. The fourth determining unit is used to determine the terminal's preset device identification code as the target device identification code when the type information indicates that the first smart card is a new smart card and the smart card status information indicates that the terminal does not have a second smart card.
