[0054] Please refer to FIG1 , which shows a schematic diagram of the architecture of the multi-functional SIM card and the card sub-system of the present application.

[0055] The card distribution system may include a user device and a server. The user device may be a mobile device such as a mobile phone, tablet computer, or mobile router (Mobile WIFI, MIFI). In the embodiments of the present application, the user device is configured with a multi-function SIM card. For example, the multi-function SIM card may be inserted into the SIM card slot of the user device or may be attached to the user device. This application does not impose any restrictions on this.

[0056] In an embodiment of the present application, the multi-function SIM card configured in the user equipment can be configured with multiple operating modes corresponding to various SIM card types. Specifically, the multi-function SIM card can support at least three operating modes, corresponding to three different remote SIM download solutions. The at least three operating modes include: eSIM card mode, STK SIM card mode, and Bluetooth SIM card mode.

[0057] Among them, the initial working mode of the multi-function SIM card is the STK SIM card mode. In this mode, the multi-function SIM card is pre-installed with a global roaming SIM card code number (i.e., seed card), and the user device can use this seed card to access the wireless network. The multi-function SIM card can interact with the server platform through the seed card network. In this mode, the multi-function SIM card has a built-in STK application, which can interact with the user device through active commands, and supports the user device to obtain information about the current access wireless network (such as seed card code number information (ICCID, IMSI) and location information (PLMN, LAC, Cell, etc.)) from the card through the LPA module, and then request card distribution. The STK application on the card can interact with the server platform through the seed card wireless network, such as through the SMS channel or the BIP channel (data channel based on BIP). When the server allocates a soft SIM card for card distribution, it can support remote card writing and operation by the platform.

[0058] When the server allocates an eSIM card, the multi-function SIM card needs to be switched to eSIM card mode. In this mode, the LPA module is first activated by the application on the user device to establish a connection with the eSIM number distribution platform (i.e., SM-DP+ platform) on the server and request to download the eSIM profile data. When the user device is an Android device, the application on the Android device selects the OMA channel through the LPA module to write the eSIM profile to the multi-function SIM card. The device can then enable this eSIM profile to stay on the network (meaning that the user device uses the SIM card to access the wireless network, and the device can use data, voice, SMS and other functions). When the user device is an iOS device, the application on the iOS device selects the Bluetooth channel through the LPA to write the eSIM profile to the multi-function SIM card. The device can then enable this eSIM profile to stay on the network. If the device application has system permissions (can access the SIM card slot), the application on the device selects the system channel through the LPA module to write the eSIM profile to the multi-function SIM card. The device can then enable this eSIM profile to stay on the network.

[0059] When the server allocates a physical SIM card, the multi-function SIM card needs to be switched to BLE SIM card mode. The application on the user's device enables the Bluetooth service to establish a connection with the Bluetooth module on the multi-function SIM card, writes the profile to the multi-function SIM card through the Bluetooth channel, and the device can enable this profile to stay on the network.

[0060] When the device application detects that an order has expired or the device has no network service, the device application will perform local profile management based on the current SIM card mode and switch the multi-function SIM card from the current mode to the STK SIM mode. For example, if the application of the user device obtains the order expiration information and the current multi-function SIM card is in the eSIM card mode, the LPA can be called to send an instruction to the SIM card through the channel supported by the device to delete the eSIM profile. After the profile is successfully deleted, the SIM card will automatically switch from the eSIM card mode to the STK SIM card mode. If the current multi-function SIM card is in the BLE SIM card mode, the Bluetooth service module in the application of the user device will no longer send heartbeat messages to the Bluetooth module of the multi-function SIM card. The multi-function SIM card will automatically delete the profile data when it detects a heartbeat timeout. After the deletion is successful, the SIM card will automatically switch from the BLE SIM card mode to the STK SIM card mode.

[0061] In some embodiments of the present application, an application (Application, APP) that can use the SIM card may be installed on the user device. APPs can be divided into iOS applications and Android platform applications according to platform type, but the functions of applications on each platform are the same.

[0062] For example, please refer to FIG2 , which shows a schematic diagram of an application in a user device and a multi-function SIM card inserted into the user device.

[0063] Among them, the application in the user device is an application designed for the multi-function SIM card and provided to the user. Its functional modules may include a user interface design (UI) module, an LPA module, a cloud service module and a BLE service module.

[0064] The multi-function SIM card is the core of this application. Its appearance can be exactly the same as the SIM card of an ordinary mobile terminal device, and the appearance can also be adjusted according to actual needs. The multi-function SIM card can be inserted into the SIM card slot of the user device, and can download various cloud SIM card resources (physical SIM card, eSIM card, soft SIM card, etc.) on the server from the remote server through the cooperation of the application and the server system, to realize the automatic switching of the functions and working modes of the STK SIM card, eSIM card, and BLE SIM card. Figure 2 shows that the multi-function SIM card includes a main control module, an STK SIM card module, an eSIM module, and a Bluetooth module. The main control module realizes interaction with the user device and realizes mode switching of the three cards.

[0065] FIG2 shows that there are five communication channels between the user equipment and the multi-function SIM card, which are marked as ①, ②, ③, ④, and ⑤ respectively.

[0066] ① The OMA channel is a programmatic interface for SIM cards that the Android system provides to applications. By calling this interface, applications can interact with the multi-function SIM card in the user device's card slot. We call this interaction between the user device and the multi-function SIM card the OMA channel.

[0067] The second type of system access refers to the permission granted by the Android or iOS system to applications to directly read and write to the multi-function SIM card in the card slot. This permission is essentially a set of standard commands. Applications interact with the multi-function SIM card on the user device by sending read and write commands to the hardware. We call this type of interaction between the user device and the multi-function SIM card the system access.

[0068] ③ A Bluetooth channel refers to a programmatic interface (API) provided by the system to applications in Android or iOS systems. Applications call this API to interact with the user device's Bluetooth module and the multi-function SIM card (which contains Bluetooth hardware and software modules). We call this method of interaction between the user device and the multi-function SIM card a Bluetooth channel.

[0069] ④BIP channel and ⑤SMS channel refer to the STK functions provided by the Android or iOS system when the multi-function SIM card is in STK SIM card mode and the user device accesses the network through the seed card SIM built into the STK SIM card. The remote server can interact with the multi-function SIM card through the user device's operating system based on the seed card's data channel and SMS channel, respectively. When the remote server interacts with the multi-function SIM card through the data channel, we call this method a BIP channel; when the remote server interacts with the multi-function SIM card through the SMS channel, we call this method an SMS channel. Because the BIP channel and SMS channel allow the server to interact directly with the multi-function SIM card through the user device's operating system, the user device's application cannot "perceive" it. Therefore, in this method, the server only needs to synchronize the multi-function SIM card's target operating mode information to the user device's application.

[0070] The UI module of the application in the user device can provide a UI interactive interface, display the traffic mall and card management interface, and implement package subscription or recharge, SIM card binding, SIM card activation and other functions under user operations.

[0071] The LPA module of the application in the user device provides a functional interface based on the standard eSIM protocol specification. When the multi-function SIM card operates in eSIM mode, the application can call this LPA interface to connect to the standard SM-DP+ platform on the remote server, download the eSIM card profile data from the SM-DP+ platform, and install the profile data on the multi-function SIM card. The LPA module can select different communication channels based on the user device operating system type and system permissions (Android systems select the OMA channel, iOS systems select the Bluetooth channel, and devices with system permissions can select the physical channel between the SIM card and the device). The eSIM profile is written to the multi-function SIM card through this communication channel and managed.

[0072] The cloud service module of the application in the user's device is a module that establishes a secure connection channel between the device application and the server and interacts with the server, such as requesting card allocation from the cloud card platform and downloading SIM card number profile data.

[0073] The BLE service module of the application in the user device requires the user device to have its own Bluetooth hardware module and support BLE4.0 and above protocols. When the multi-function SIM card works in BLE mode, it can query the SIM card Bluetooth pairing information from the cloud card platform, establish a Bluetooth connection with the SIM card through the BLE service, transmit profile data, and maintain a long connection with the multi-function SIM card Bluetooth module by sending heartbeat data.

[0074] In an embodiment of the present application, the user device can establish a connection with the server based on the above-mentioned application, send a card division request to obtain the SIM card type and SIM card code number assigned by the server, and then control the SIM card to enter the corresponding working mode, select the matching communication channel according to the working mode to complete the writing of the SIM card code number into the multi-function SIM card, and enable the SIM card code number to stay on the network.

[0075] Specifically, the server may have a cloud card platform built in. As shown in FIG3 , the cloud card platform may include a code number management module, an order service module, and a cloud card service module.

[0076] The code management module can maintain the basic information of the multi-function SIM card, which can include information about the pre-installed seed card on the SIM card, Bluetooth pairing information, and cloud card code resource information.

[0077] The information of the seed card may include but is not limited to the identification code of the seed card, such as ICCID, IMSI, and MSISDN. Bluetooth pairing information includes but is not limited to Bluetooth name, pairing key, and Bluetooth data key. Cloud card code resources can be divided according to SIM card type, soft SIM card, eSIM card, and physical SIM card. Soft SIM card code information may include IMSI, KI, and POC. eSIM card code information may include an activation code. P-SIM code information may include ICCID and IMSI. Among them, the ICCID and IMSI of the P-SIM can be read from the card by the card-carrying device and automatically uploaded to the cloud card platform.

[0078] The order service module can manage SIM card package orders from different user portals (such as websites, third-party e-commerce platforms, etc.), and maintain information such as order status, activation time, validity period, expiration time, product service scope, etc.

[0079] The Cloud Card Service Module receives card assignment requests, schedules and assigns the appropriate SIM card number, and returns a response. Furthermore, upon receiving a Bluetooth pairing query, the Cloud Card Service Module returns SIM card Bluetooth pairing information and, upon receiving a profile download request, returns profile data. Furthermore, the Cloud Card Service Module maintains a persistent TCP connection with the user device and forwards authentication requests and responses from the physical Cloud Card.

[0080] In some implementations of the present application, referring to FIG3 , the card splitting system may further include an OTA platform, a data center, a card carrier device, and an SM-DP+ platform.

[0081] The OTA platform can receive SIM card operating mode notification information reported by the SIM card and forward the SIM card operating mode notification to the cloud card platform. In addition, the OTA platform also supports receiving card writing result notifications reported by the STK SIM card and forwarding the result notification to the cloud card platform. It should be noted that the OTA platform and the cloud card platform can be placed on the same server or different servers, and this application does not impose any restrictions on this.

[0082] The data center is used to maintain various types of information required by the card distribution system, such as the aforementioned SIM card pre-set seed card information, Bluetooth pairing information, cloud SIM card code type and information, order status, order allocation information, etc. The order status may specifically include the order number, the SIM card ICCID (seed card) bound to the order, the order activation status, the activation time, the expiration time, and the package. The order allocation information may specifically include the SIM card ICCID bound to the order, the order number, the order allocation code number (SIM card code number ICCID, IMSI), the code number type, the time for allocating the SIM card code number, and the time for recycling the SIM card code number. The package defines the service range and time. For example, if a user subscribes to a 7-day package of "XX" for a multi-function SIM card, it means that the current service range of the SIM card is "XX" and the service time is 7 days (starting from the activation time, such as the activation start time after the user successfully clicks to activate the SIM card through the UI).

[0083] The card carrier device is the SIMBank device, which can read the physical card information in the card slot, report the physical card information to the data center, and support remote authentication of the SIM card.

[0084] The SM-DP+ platform is the operator's eSIM profile hosting platform, which supports the device application LPA service to download the eSIM profile from the SM-DP+ platform through the activation code.

[0085] It can be understood that Figures 1 and 3 are merely schematic diagrams of the card splitting system and do not constitute a limitation on the card splitting system. In the implementation of the present application, the card splitting system may also include more or fewer devices or components, for example, it may also include a gateway, a bus, etc., and this application does not impose any restrictions on this.

[0086] In combination with the card distribution system shown in Figures 1 and 3, and the application shown in Figure 2, Figure 4 shows a schematic flow chart of an implementation method for allocating a multi-functional SIM card provided in an embodiment of the present application, which can be applied on a server.

[0087] Specifically, the method for allocating a multi-function SIM card may include the following steps S401 to S403.

[0088] Step S401: receiving a card splitting request sent by a user device.

[0089] In an embodiment of the present application, after inserting a SIM card at a destination, the user device can activate the SIM card through the UI module and send a card splitting request to the server cloud card platform to obtain the SIM card number. The card splitting request may carry the identification code and first location information of the SIM card inserted into the user device. The identification code can be used to identify the SIM card inserted into the user device and may refer to the seed card ICCID pre-set on the aforementioned multi-function SIM card. The first location information can be used to identify the current location area of ​​the multi-function SIM card and may refer to the PLMN, LAC, or Cell where the seed card is currently located.

[0090] Step S402: determining a target type among multiple SIM card types according to the identification code and the first location information.

[0091] In an embodiment of the present application, the multiple SIM card types include at least a physical SIM card, an eSIM card, and a virtual SIM card. Based on the identification code and the first location information, the server can determine a target type that can be used by the SIM card inserted into the user equipment from among the multiple SIM card types supported by the multi-function SIM card.

[0092] Step S403: Send first response information to the user equipment.

[0093] The first response information may include first type information of the target type and the SIM card code number of the target type. The first type information may be an indication of the SIM card operating mode, used to instruct the multi-function SIM card inserted into the user equipment to enter the target operating mode corresponding to the target type among multiple operating modes, so that the user equipment completes the writing of the SIM card code number and stations on the network according to the communication channel corresponding to the target operating mode. Specifically, the multi-function SIM card inserted into the user equipment may support at least three different operating modes: STK SIM card mode, BLE SIM card mode, and eSIM card mode.

[0094] The multi-function SIM card is pre-configured with the seed card and OTA platform address (IP:port list). In STK SIM card mode, after the seed card is activated and successfully registered, the SIM card interacts with the user device through proactive commands (e.g., Proactive UICC commands), periodically obtaining registration information from the user device and storing it on the SIM card. When the user activates the SIM card through the UI, the user device application uses the LPA service to select a matching channel to issue commands to obtain current registration information from the SIM card and submit a card assignment request. The SIM card proactively reports the SIM card mode notification to the OTA platform based on the pre-configured OTA platform address and establishes a data channel (based on the BIP protocol) with the OTA platform. This registration information includes, but is not limited to, network type (e.g., LTE, UTRAN, GSM), PLMN, LAC, and Cell. If the server cloud card platform allocates a soft SIM card, the device application does not need to process it. The OTA platform can encapsulate the soft SIM card's profile data into a STK data SMS packet and send it via the GPRS SMS gateway to the destination mobile user number (i.e., the pre-configured seed card MSISDN). The card receives the OTA data SMS message, parses it, and completes the card writing process. After the card writing is successful, the card reports the writing result to the OTA platform via the SMS channel. The OTA platform can also send the packaged soft SIM card data packet to the SIM card via the BIP channel. Once the card writing is complete, the OTA platform will be notified of the card writing result.

[0095] The OTA platform forwards the card writing result to the cloud card platform. When the cloud card platform receives the card writing result notification, it updates the order activation status, activation time, expiration time, and generates order allocation information.

[0096] In BLE SIM card mode, the multi-function SIM card can support Bluetooth 4.0 and above Bluetooth protocols. The user device establishes a Bluetooth connection between its own Bluetooth module and the Bluetooth of the multi-function SIM card, maintains a long connection by sending heartbeat data, and interacts with the card through the Bluetooth channel. The user device can send a SIM card Bluetooth pairing information query request to the cloud card platform through the application, and based on the returned SIM card Bluetooth pairing information, start the BLE service module of the application to establish a Bluetooth connection with the SIM card. After the Bluetooth connection is successful, the user device can send instructions through the Bluetooth channel to notify the SIM card to switch to BLE SIM card mode. At the same time, the cloud service module of the application sends a SIM card code profile download request to the cloud card platform. After receiving the SIM card code profile data returned by the cloud card platform, it is sent to the SIM card via the Bluetooth channel.

[0097] Specifically, if the SIM card number is being downloaded to a physical SIM card, the application can initiate a periodic polling mechanism to query the SIM card for authentication requests, forward them to the cloud card platform for remote authentication, and send heartbeat packets to maintain a persistent TCP connection with the cloud card platform. If the SIM card number is being downloaded to a virtual SIM card, the application can disconnect from the cloud card platform after completing the number download.

[0098] In eSIM mode, the user device application selects a suitable communication channel based on the device type and system permissions, and sends a command to the multi-function SIM card through the LPA module, instructing the SIM card to switch to BLE SIM mode. The LPA then downloads the eSIM profile data from the SM-DP+ platform to the local computer using the eSIM activation code. It then selects a suitable communication channel based on the device type and system permissions to write the eSIM profile data to the multi-function SIM card.

[0099] Specifically, for iOS user devices, the device application activates the BLE service to establish a Bluetooth connection with the multi-function SIM card Bluetooth module and sends heartbeats to maintain a persistent connection. The device application then activates the LPA to issue a command via the Bluetooth channel, instructing the SIM card to switch its operating mode to eSIM mode. The device application activates the LPA module, uses the eSIM activation code, downloads the eSIM profile data from the SM-DP+ platform, and sends the eSIM profile data to the multi-function SIM card via the Bluetooth connection channel.

[0100] Specifically, for Android user devices, the device application activates the LPA module, selects the OMA channel, issues a command to the card, notifies the SIM card to switch to eSIM mode, downloads the code profile data from the SM-DP+ platform, and sends the eSIM profile data to the multi-function SIM card via the OMA channel. Of course, if the Android user device application has system permissions, the LPA module can select the system channel between the SIM card and the user device to write the eSIM profile data to the multi-function SIM card via the physical channel between the SIM card and the device.

[0101] Accordingly, if the target type is determined to be a physical SIM card, the multi-function SIM card inserted into the user device can enter BLE SIM card mode, and the corresponding communication channel for BLE SIM card mode is the Bluetooth channel. After the user device downloads the physical SIM card number profile data from the cloud card platform, it can perform a card write operation over the Bluetooth channel, allowing the user device to access the network based on the SIM card number of the physical SIM card. After the card write is successful, the user device application reports the card write result to the cloud card platform.

[0102] If the target type is an eSIM card, the SIM card inserted into the user device can enter the eSIM card mode, and the communication channel corresponding to the eSIM card mode is any one of the OMA channel, Bluetooth channel, and system channel. Similarly, after the user device successfully downloads the eSIM profile from the SM-DP+ platform, the user device can write the SIM card code number into the multi-function SIM card based on the Bluetooth channel, and use the SIM card code number in the multi-function SIM card to stay on the network. After the card is successfully written, the user device receives the eSIM profile installation result reported by the card, and can report the card writing result to the cloud card platform through the SIM card code network or the pre-set seed card network.

[0103] If the target type is a soft SIM card, the SIM card inserted into the user device can enter STK SIM card mode or BLE SIM card mode. The corresponding communication channel for STK SIM card mode is the SMS channel or the BIP channel. The OTA platform can send the soft card information to the card through the SMS channel or the BIP channel for card writing, allowing the user device to log on to the network based on the SIM card number of the soft SIM card. After the card writing is successful, the card will report the card writing result.

[0104] In this way, the user equipment can write the SIM card code data into the multi-function SIM card according to the communication channel corresponding to the target working mode and stay on the network.

[0105] In step S402, the server may query the order information bound to the SIM card inserted into the user equipment according to the identification code and the first location information, and determine the assignable candidate types from the multiple SIM card types according to the order information, and then determine the target type from the candidate types.

[0106] The candidate type refers to the SIM card number type currently available for the multi-function SIM card, which can be determined, for example, based on the package information in the user's order. For the assignable SIM card number candidate types, the server can select any one of them as the target type.

[0107] In some embodiments, the server may determine the data traffic cost of the user device using each candidate type of SIM card number to access the network, and then determine the target type from the candidate types based on the data traffic cost. The data traffic cost is the cost of purchasing the SIM card from the operator (such as China Mobile, China Unicom, etc.) by the SIM card service provider (such as a virtual operator).

[0108] For example, the candidate type with the lowest traffic cost can be selected as the target type.

[0109] In some specific implementations, the server can first determine whether there is a valid order bound to the SIM card based on the identification code, and determine whether the first location information is within the service range of the product in the valid order based on the first location information. If there is a valid order and the first location information is within the service range, the available SIM card types within the service range can be obtained as candidate types, and then the target type can be determined from the candidate types based on the traffic cost.

[0110] In other implementations, the server may also directly query the card sorting priority order corresponding to the first position information of the order item according to the first position information, so as to determine the target type from the candidate types according to the card sorting priority order.

[0111] The card allocation priority order specifically refers to the allocation order of physical SIM cards, eSIM cards, and soft SIM cards. The card allocation priority order may vary for different product and service scopes. Based on the service scope of the first location information, the target type may be determined from the candidate types according to the corresponding card allocation priority order.

[0112] After determining the target type, the server can obtain the SIM card code number of the target type through the cloud card platform, and in step S403, send a first response message to the user device. Preferably, the SIM card code number of the target type can be the local SIM card code number associated with the first location information in the SIM card code number of the target type. The local SIM card code number is the code number of the local SIM card (Local SIM). Compared with the seed card, the user device has a lower cost and better signal when stationed in the current location based on the local SIM card code number, which helps to improve the stationing experience.

[0113] After receiving the first response information, the application of the user device can control the SIM card to enter the target working mode corresponding to the target type, so that the user device writes the SIM card code number data into the multi-function SIM card according to the communication channel corresponding to the target working mode and stays on the network based on the written SIM card code number.

[0114] In the embodiment of the present application, when the multi-function SIM card meets the switching condition, it can also be switched to the initial working mode (STK SIM card mode).

[0115] In some embodiments of the present application, the SIM card is set to the initial working mode when it leaves the factory, that is, it is in the STK SIM card mode, and the seed card is enabled to stay on the network. Specifically, the SIM card can enter the STK SIM card mode by default when it is powered on for the first time, and the seed card is enabled to stay on the network. When the SIM card is not powered on for the first time, it can directly enter the last working mode and stay on the network according to the profile data that has been obtained.

[0116] In other embodiments of the present application, the user device may confirm that the multi-function SIM card inserted in the user device meets the switching conditions if the order bound to the multi-function SIM card inserted in the user device has expired. The user device may also confirm that the multi-function SIM card inserted in the user device meets the switching conditions if the multi-function SIM card inserted in the user device is outside the service range and cannot provide network service. The service range is the service range of the SIM card number currently used by the multi-function SIM card inserted in the user device. If the service range is exceeded, the SIM card number cannot provide network service.

[0117] More specifically, after completing the SIM card code allocation and writing, if the current working mode of the multi-function SIM card is STK SIM card mode, if the SIM card order expires, or the current location of the SIM card is not within the service range recorded by the SIM card code number, the SIM card can automatically delete the profile data in the SIM card. At this time, the working mode of the SIM card can automatically switch to the initial STK SIM card mode, re-enable the seed card network, and actively report the SIM card mode notification to the OTA platform.

[0118] If the current operating mode is eSIM card mode, and the device application determines that the SIM card order has expired or the SIM card is out of service range and cannot provide network services normally, the user device application can activate the LPA module to perform local operations on the eSIM profile data. If the order has expired, the user device application can activate the LPA module to send a command to the SIM card to instruct the SIM card to delete the eSIM profile data. If network services cannot be provided normally, the user device application can activate the LPA module to send a command to the SIM card to instruct the SIM card to disable the eSIM profile data. After the SIM card successfully deletes or disables the eSIM profile data, it automatically switches back to the initial STK SIM card mode, re-activates the seed card network, and proactively reports to the OTA platform. The LPA module also notifies the SM-DP+ platform of the results of the local operation on the eSIM profile data.

[0119] If the multi-function SIM card is currently operating in BLE SIM mode, the device application can determine that the SIM card order has expired or the SIM card is out of service range and cannot provide network services normally. The user device application can activate the BLE service and stop sending Bluetooth heartbeat data to the SIM card. The SIM card will automatically delete the P-SIM profile data after determining that the heartbeat has timed out and the Bluetooth connection is disconnected. After the SIM card successfully deletes the P-SIM profile, it automatically switches back to the initial STK SIM card mode, re-enables the seed card profile data, and proactively sends a SIM card mode notification to the OTA platform.

[0120] After receiving a SIM card mode notification triggered by a SIM card operating mode switch, the OTA platform forwards it to the Cloud Card Platform. Upon receiving this notification, the Cloud Card Platform confirms that the Cloud Card profile data no longer exists on the SIM card. This SIM card mode notification includes the SIM card identification code, the SIM card profile recovery scenario identifier (00: initial mode, 01: out of service range, 02: expired), and the seed card's network location information (PLMN, LAC, Cell). Based on the SIM card identification code, scenario identifier, and current location, the Cloud Card Platform determines whether the SIM card number in the multi-function SIM card's assigned order information is recoverable. If the order has expired, the SIM card number in the order allocation information is recovered, the SIM card number allocation status is updated, and the order number issuance status is updated. If the current location is out of service range, but the order has not expired, no recovery operation is performed; only the number issuance status is updated. If the user device changes location and triggers a card allocation request again, the server Cloud Card Platform can issue the same SIM card number.

[0121] 5 , the present application further provides a method for allocating a multi-function SIM card, which is applied to a user device. The method for allocating a multi-function SIM card may specifically include the following steps S501 to S503 .

[0122] Step S501: When the working mode of the multi-function SIM card is the initial working mode, a card separation request is sent to a server.

[0123] The card distribution request may carry the identification code and first location information of the SIM card inserted into the user equipment.

[0124] Step S502: obtaining first response information fed back by the server based on the identification code and the first location information, and controlling the multi-function SIM card to enter a corresponding working mode and stay on the network according to the first response information.

[0125] The first response information may include first type information of a target type and a SIM card number of the target type. The target type is determined by the server based on the identification code and the first location information from among multiple SIM card types. Based on the first type information, the user equipment may control the multi-function SIM card to enter a target operating mode corresponding to the target type among the multiple operating modes, and to establish network access using the communication channel and SIM card number corresponding to the target operating mode.

[0126] In some embodiments of the present application, if the target type is a physical SIM card, the user device can control the multi-function SIM card to enter BLE SIM card mode, and the corresponding communication channel of BLE SIM card mode is the Bluetooth channel. The user device can then write the SIM card number to the multi-function SIM card via the Bluetooth channel, so that the SIM card number in the multi-function SIM card can be used to log on to the network.

[0127] If the target type is an eSIM card, the user device can control the multi-function SIM card to enter eSIM card mode. The communication channel corresponding to the eSIM card mode is any one of the OMA channel, Bluetooth channel, and system channel. The user device can then write the SIM card number to the multi-function SIM card through any of the OMA channel, Bluetooth channel, and system channel to access the network using the SIM card number in the multi-function SIM card.

[0128] If the target type is a soft SIM card, the user device can control the multi-function SIM card to enter STK SIM card mode or BLE SIM card mode. The corresponding communication channel for STK SIM card mode is the SMS channel or BIP channel. The user device can then write the SIM card number to the multi-function SIM card through any of the SMS channel, BIP channel, or Bluetooth channel, allowing the user device to use the SIM card number in the multi-function SIM card to stay on the network.

[0129] Step S503: During the network stationing process, if the multi-function SIM card meets the switching condition, the multi-function SIM card is switched to the initial working mode.

[0130] In some embodiments of the present application, when the SIM card inserted into the user equipment meets the switching condition, the multi-function SIM card can be switched to the initial working mode and the seed card can be enabled to stay on the network.

[0131] Specifically, when the multi-function SIM card is powered on for the first time, it is in the initial working mode set by the factory, the seed card is enabled to stay on the network, and a SIM card mode notification is reported.

[0132] When the order bound to the multi-function SIM card expires, the user device can confirm that the multi-function SIM card meets the switching conditions, switch the multi-function SIM card to the initial working mode, enable the seed card configured on the multi-function SIM card to stay on the network, and report the SIM card mode notification.

[0133] If a multi-function SIM card exceeds its service range and cannot provide network access, the user device can confirm that the multi-function SIM card meets the switching conditions, switch the multi-function SIM card to the initial working mode, activate the seed card configured for the multi-function SIM card to stay on the network, and report the SIM card mode notification. The service range is the service range of the SIM card code currently used by the multi-function SIM card inserted in the user device.

[0134] It is understandable that the onboarding process of the user equipment can refer to the descriptions of Figures 1 to 4, and this application will not go into details.

[0135] For ease of understanding, please refer to FIG6 , which shows a flow chart of the card-splitting system of the present application for implementing user equipment stationing on the network.

[0136] First, the multi-function SIM card's card information can be imported into the cloud card platform's data center. Users can order SIM card packages through an app or other portal. After receiving the order, the cloud card platform selects the multi-function SIM card for shipment and generates a binding between the SIM card identification code and the order. After receiving the multi-function SIM card, the user can use the device app to bind the SIM card identification code, manage the SIM card, and renew and recharge it. After inserting the card at their destination, the user opens the device app to query the currently subscribed package for the bound SIM card. If the destination package is not yet activated, they can activate the SIM card and send a card assignment request to the cloud card platform server. After the user device receives the first response from the cloud card platform, the user device app selects a matching communication channel based on the device's operating system type and system permissions to issue a command to the card, instructing the SIM card to switch to the target operating mode corresponding to the target type. After the user device app successfully downloads the SIM card code profile data, it selects a matching communication channel to write the SIM card code data to the multi-function SIM card. After the card write is successful, the SIM card code is enabled to be stationed on the network, and the write results are generated and reported.

[0137] Referring to Figure 7, if a multi-function SIM card order has expired or is out of service range, the user device can determine the operating mode of the multi-function SIM card. If the current operating mode is STK SIM card mode, the application does not need to take any action. The multi-function SIM card will automatically determine that the currently enabled SIM card number has expired, automatically delete the SIM card number, reactivate the seed card, and proactively report a SIM card mode notification. If the current operating mode is eSIM card mode, the device application can use the LPA module to issue a command instructing the eSIM card to disable or delete the eSIM profile. Specifically, if the multi-function SIM card order has expired, the LPA module issues a command instructing the eSIM card to delete the eSIM profile. If the multi-function SIM card is out of service range, the LPA module issues a command instructing the eSIM card to disable the eSIM profile. This allows the multi-function SIM card to be reused when it returns to service range. After the card successfully disables or deletes the eSIM profile, it is restored to factory settings, automatically switches back to STK SIM card mode, reactivates the seed card, and proactively reports a SIM card mode notification. The LPA also notifies the SM-DP+ platform of the results of the local eSIM profile operation. If the current operating mode is BLE SIM card mode, you can start the BLE service and stop sending Bluetooth heartbeat data. The SIM card will automatically delete the P-SIM profile data after determining that the Bluetooth heartbeat has timed out. After the card successfully deletes the P-SIM profile data, it will restore the card to factory settings, automatically switch back to STK SIM card mode, re-enable the seed card network, and actively report the SIM card mode notification.

[0138] The cloud card platform receives the SIM card mode notification reported by the card and can confirm that the SIM card code profile is no longer on the card. It can also determine whether the code needs to be recycled based on whether the order corresponding to the SIM card identification code has expired. At the same time, the code issuance status in the order allocation information is updated.

[0139] In an embodiment of the present application, when the working mode of the multi-function SIM card is the initial working mode, a card division request is sent to the server, and first response information fed back by the server based on the identification code and the first location information is obtained. The multi-function SIM card is controlled to enter the corresponding working mode and stay on the network according to the first response information. Then, according to the usage scenario of the SIM card, it can be controlled to enter the working mode corresponding to the code number of different SIM card types (for example, physical SIM card, eSIM card or soft SIM card). At the same time, during the network stationing process, if the multi-function SIM card meets the switching conditions, the multi-function SIM card is switched to the initial working mode, so that different types of SIM cards can be used on a single SIM card, thereby improving the scenario adaptability of the SIM card, while improving the service capabilities of the SIM card service provider and optimizing operating costs.

[0140] It should be noted that, for the sake of simplicity of description, the aforementioned method embodiments are all expressed as a series of action combinations. However, those skilled in the art should be aware that this application is not limited to the described order of actions, because according to this application, certain steps can be performed in other orders.

[0161] As shown in Figure 10, a schematic diagram of an electronic device provided in an embodiment of the present application is provided. Specifically, the electronic device 10 may include: a processor 100, a memory 101, and a computer program 102 stored in the memory 101 and executable on the processor 100, such as a SIM card allocation program or a resident program.
