[0027] Combination Figure 1As shown, this disclosure provides a binding method for eSIM terminal operators. The binding method can be executed by the processor of the eSIM terminal, and the binding method includes: S101, the processor loads a general policy in the eSIM terminal.

[0028] The eSIM terminal has a pre-installed general policy and an extensible policy area; the general policy supports basic communication with multiple operators; the extensible policy area dynamically loads operator-specific policies through the cloud to support operator-specific communication.

[0029] S102: After completing the subscription to the target operator's package, the processor downloads the target cloud policy from the scalable policy area, activates the eSIM primary card according to the primary number information, and switches the general policy of the eSIM terminal to the target cloud policy.

[0030] S103, the processor obtains the encryption policy package of the target operator, activates the target cloud policy according to the encryption policy package, and registers with the target operator's network.

[0031] S104: After the target operator's plan expires, the processor switches the target cloud policy of the eSIM terminal to a general policy.

[0032] In this embodiment, after a user subscribes to a target operator's plan, the operator-specific policy is dynamically loaded into the extensible policy area of ​​the eSIM terminal. The eSIM primary card is activated based on the primary number information, and the general policy is switched to the target cloud policy, supporting real-time updates and switching of operator policies. By obtaining the target operator's encrypted policy package and activating the target cloud policy based on the encrypted policy package, the security of policy transmission and activation is ensured, preventing policy tampering or forgery. Therefore, users can independently select a target operator's plan in the eSIM terminal and dynamically adjust the operator policy by loading the operator-specific policy in the cloud, thereby improving the flexibility of users in choosing an eSIM terminal operator. Furthermore, after the target operator's plan expires, the eSIM terminal can automatically switch the target cloud policy to a general policy, avoiding communication interruptions caused by plan expiration and providing users with the opportunity to reselect an operator, further improving the user's flexibility and autonomy in operator selection.

[0033] Optionally, the general policy conforms to the RAT (Radio Access Technology) rules defined in the GSMA (Global System for Mobile Communications Association) specification.

[0034] Optionally, the scalable policy area supports the coexistence of multiple carrier-specific policies, but only one policy is effective at a time, in accordance with the GSMA remote subscription management specification.

[0035] Optionally, the primary number information includes the user's original mobile phone number. The original mobile phone number is a number from the target operator.

[0036] Optionally, the subscription to the target operator's package can be completed as follows: based on the target operator's package selected by the user, a subscription request is sent to the target operator's platform; the encrypted signing certificate returned by the target operator's platform is obtained; if the validity of the encrypted signing certificate is verified, the primary number information is synchronized to the eSIM primary card to complete the binding of the target operator's package.

[0037] Combination Figure 2 As shown, this disclosure provides a method for completing a subscription to a target operator's service plan. The execution entity of this method can be the processor of an eSIM terminal, and the method includes: S201, the processor sends a subscription request to the target operator's platform based on the target operator's selected plan.

[0038] S202, the processor obtains the encrypted subscription certificate returned by the target operator platform.

[0039] S203: Once the validity of the encrypted subscription certificate is verified, the processor will synchronize the primary number information to the eSIM primary card to complete the binding of the target operator's package.

[0040] In this embodiment, users can select a target operator's plan from various operator options via the eSIM terminal's user interface. After selection, the eSIM terminal generates a subscription request containing the selected plan information, terminal device identifier, and user identity information. The eSIM terminal sends the subscription request to the target operator's platform via a secure network connection. Upon receiving the request, the operator's platform verifies its legitimacy and generates an encrypted subscription certificate. This encrypted subscription certificate typically contains the user's plan information, the operator's digital signature, and validity period. Upon receiving the encrypted subscription certificate, the eSIM terminal decrypts and verifies it using the operator's public key. Verification includes the certificate's integrity, signature validity, and validity period. After verifying the encrypted subscription certificate's validity, the eSIM terminal synchronizes the user-input primary number information to the eSIM primary card. The eSIM primary card activates the target operator's plan based on the synchronized primary number information and the subscription certificate, completing the binding process. The subscription request and subscription certificate are transmitted via an encrypted communication channel to prevent data theft or tampering during transmission. The operator's digital certificate is used to sign and verify the subscription certificate, ensuring its legitimacy and integrity and preventing forgery and tampering. The secure storage feature of the eSIM primary card ensures the secure storage of primary number information and subscription credentials, preventing data leakage.

[0041] Optionally, the binding method for eSIM terminal operators also includes: simultaneously activating the secondary card communication function when activating the eSIM primary card.

[0042] In this embodiment, the communication functions of the primary and secondary SIM cards in the eSIM terminal are typically managed jointly by the eSIM chip and the terminal device's communication module. When a user completes a subscription to a target operator's plan and verifies the encrypted subscription credential, the eSIM primary card is activated. At this time, the eSIM terminal triggers a synchronization mechanism, simultaneously activating the communication function of the secondary card. Users can use both the primary and secondary cards simultaneously on the same device, meeting communication needs in different scenarios and improving the device's practicality. Through eSIM technology, the device can also flexibly switch operator plans and support multi-SIM communication, giving the device greater versatility and flexibility across different operator networks.

[0043] Optionally, the target operator generates the encryption policy package as follows: the policy package is generated based on RTA rules, billing policies, timestamps, and eSIM terminal fingerprint information; the policy package is encrypted using the SM2 / SM4 algorithm to generate an encrypted policy package; and the encrypted policy package is distributed to the eSIM terminal through the device manufacturer's secure channel.

[0044] Combination Figure 3 As shown, this disclosure provides a method for generating an encryption policy package. The execution entity of this method can be the processor of the target operator platform. The method includes: S301, the processor generates a policy package based on RTA rules, billing policies, timestamps and eSIM terminal fingerprint information.

[0045] S302, the processor uses the SM2 / SM4 algorithm to encrypt the policy packet and generate an encrypted policy packet.

[0046] S303: The processor sends the encryption policy package to the eSIM terminal through the device manufacturer's secure channel.

[0047] In this embodiment, the RTA rule defines the wireless network access technologies supported by the eSIM terminal, ensuring that the device can communicate normally in the target operator's network. The target operator's billing rules are embedded in the policy packet so that the eSIM terminal can perform billing management according to these rules. Timestamp information is used to identify the time the policy packet was generated, which can be used to verify the freshness of the policy packet and prevent the use of expired or duplicate policy packets. Fingerprint information is used to ensure the binding of the policy packet to a specific terminal device, preventing the policy packet from being used by other devices. The policy packet is encrypted using the SM2 / SM4 algorithm to ensure that it is not stolen or tampered with during transmission. The digital signature function of the SM2 algorithm further ensures the integrity and source credibility of the policy packet. The policy packet is distributed through a secure channel provided by the device manufacturer, ensuring the security and integrity of the policy packet during transmission. A two-way authentication mechanism further ensures that only legitimate eSIM terminals can receive the policy packet.

[0048] Optionally, the binding method for eSIM terminal operators also includes: verifying the operator platform identity via a digital certificate after obtaining the encryption policy package.

[0049] In this embodiment, after receiving the encrypted policy packet, the eSIM terminal first extracts the digital certificate provided by the operator platform. The terminal verifies the certificate chain to ensure that the operator certificate was issued by a trusted CA. Verifying the operator platform's identity through the digital certificate ensures the policy packet originates from a trusted operator, preventing man-in-the-middle attacks or forged policy packets from being accepted by the terminal device. Signature verification ensures the policy packet has not been tampered with during transmission, enhancing the overall system security. Combining timestamps and device fingerprint information further prevents attackers from replaying old policy packets.

[0050] Optionally, the binding method for eSIM terminal operators also includes: pushing a renewal reminder to the user within a preset time before the target operator's plan expires; and renewing the target operator's plan in response to the user's renewal request.

[0051] Combination Figure 4 As shown in the embodiments of this disclosure, another binding method for eSIM terminal operators is provided, including: S401, the processor loads a general policy in the eSIM terminal.

[0052] S402: After completing the subscription to the target operator's package, the processor downloads the target cloud policy from the scalable policy area, activates the eSIM primary card according to the primary number information, and switches the general policy of the eSIM terminal to the target cloud policy.

[0053] S403, the processor obtains the target operator's encryption policy package, activates the target cloud policy according to the encryption policy package, and registers with the target operator's network.

[0054] The S404 processor sends a renewal reminder to the user within a preset time before the target operator's plan expires.

[0055] The S405 processor responds to a user's renewal request and renews the target carrier's plan.

[0056] S406: After the target operator's plan expires, the processor switches the target cloud policy of the eSIM terminal to a general policy.

[0057] In this embodiment, a timer is set in the eSIM terminal to monitor the validity period of the target operator's plan. A preset time threshold is set, such as 72 hours before the plan expires. When the plan's validity period reaches this threshold, a renewal reminder process is triggered. A renewal reminder message is pushed to the user through the eSIM terminal's user interface. The reminder message should include the plan's expiration time, renewal options, and operation instructions. In addition to text reminders, sound, vibration, etc., can also be used to attract the user's attention. The user selects the renewal option through the terminal device's user interface, triggering the renewal process. The terminal device generates a renewal request, including user identity information, plan information, and device identifier. The terminal device sends the renewal request to the target operator's platform through a secure communication channel. The operator's platform processes the renewal request, generates a new encryption policy package, and returns it to the terminal device through a secure channel. The terminal device receives the new encryption policy package returned by the operator's platform and verifies its validity using a digital certificate. After successful verification, the terminal device activates the new encryption policy package and updates the eSIM terminal's configuration information. Proactively pushing renewal reminders to users before the plan expires avoids service interruptions due to users forgetting to renew, ensuring service continuity and improving the operator's user retention rate.

[0058] Optionally, the binding method for eSIM terminal operators also includes: when the user selects a new operator, switching the target cloud policy or general policy of the eSIM terminal to the cloud policy corresponding to the new operator.

[0059] In this embodiment, users can select a new operator plan through the eSIM terminal's user interface. After the user selects a new operator, the terminal device sends an unbinding request to the current operator's platform, terminating the current operator's policy. Simultaneously, the terminal device sends a binding request to the new operator's platform, requesting to obtain the new operator's cloud policy. Upon receiving the binding request, the new operator's platform generates and returns an encrypted policy package. The terminal device receives and verifies the new operator's encrypted policy package. The terminal device switches its current operator policy (target cloud policy or general policy) to the new operator's cloud policy. The terminal device updates its eSIM configuration according to the new policy package and re-registers with the new operator's network. Users can seamlessly switch operators on the same device without changing the physical SIM card or performing complex manual settings, improving the user experience. The terminal device supports dynamic policy updates, enabling real-time operator switching based on user selection, enhancing the system's flexibility and adaptability.

[0060] Optionally, the binding method for eSIM terminal operators also includes: when the user chooses to use a general policy, synchronizing the primary number information according to the operator selected by the user, and activating the eSIM primary card and secondary card according to the primary number information.

[0061] In this embodiment, the user selects a universal policy through the eSIM terminal's user interface and simultaneously designates an operator as the current network service provider. The user enters primary number information, and the terminal device binds this information to the user-selected operator. The terminal device sends the primary number information to the designated operator's platform via a secure communication channel, requesting activation of the primary number. The terminal device receives an activation response from the operator's platform, confirming successful synchronization of the primary number information. The terminal device activates the eSIM primary card based on the primary number information and simultaneously activates the communication function of the secondary card. The activation process includes configuring network access parameters and registering with the operator's network. The user's ability to choose a universal policy and designate an operator as the current network service provider enhances the user experience. The terminal device's support for universal policies allows users to flexibly switch between different operators, increasing system flexibility.

[0062] In one specific embodiment, when purchasing an eSIM terminal device, the user selects the "Contractual Handset Discount Purchase" plan and pays the corresponding fee. After payment, the terminal device prompts the user to select an operator plan and complete the electronic contract signing via the user interface. The device sends an activation request to the operator platform, obtains the encryption policy package, and activates the primary SIM card. Simultaneously, according to the operator's policy, the secondary SIM card's communication function is activated, but the secondary SIM card is disabled when the primary SIM card is deactivated. Users can enjoy purchase discounts through the "Contractual Handset Discount Purchase" plan, reducing the cost of purchasing a device. At this time, the eSIM terminal needs to support the linked management of the primary and secondary SIM cards, ensuring that the secondary SIM card's communication function depends on the status of the primary SIM card. The terminal device supports the activation of operator-specific policies, meeting the operator's business needs. The linkage mechanism between the primary and secondary SIM cards enhances the device's adaptability to operator policies.

[0063] In another specific embodiment, when purchasing an eSIM terminal device, the user selects the "original device purchase" option, excluding participation in the operator's promotional purchase activities. The user selects a new operator through the terminal device's user interface and completes the operator switching process. The communication functions of the primary and secondary SIM cards are independent and unaffected by the status of the other. Users can freely choose the operator for either the primary or secondary SIM card, and the secondary SIM card can still be used normally even if the primary SIM card is deactivated. Users can freely switch operators without being restricted by the purchase agreement, enhancing user autonomy. The independent communication functions of the primary and secondary SIM cards allow users to use them flexibly as needed, improving the device's practicality. The terminal device supports dynamic operator switching, enhancing the system's flexibility and versatility. The independent communication functions of the primary and secondary SIM cards support diverse user needs in different scenarios.

[0064] The binding method for eSIM terminal operators provided in this disclosure allows users to pay only for device hardware costs, with operator services provided through subscriptions. This avoids mandatory handset purchases and binding, breaks the physical bond between the SIM card and the terminal device, supports switching operators at any time, protects user rights, and eliminates the need for customized physical cards or pre-installed multiple eSIM versions, thus optimizing operator costs. Furthermore, by incorporating national cryptographic algorithms and device manufacturer certifications, it complies with GSMA specifications, enhancing the security of policy distribution.
