[0049] To facilitate understanding of the technical solution of the eSIM migration method in the embodiment of the present application, first, the structure of the eSIM card in the embodiment of the present application is described.

[0050] Figure 2 A schematic diagram of the structure of the eSIM card in the embodiment of the present application is shown. Figure 2 As shown, the eSIM card in this application is an electronic SIM card, which is based on the mature technical standards and practices of SIM cards (Subscriber Identification Module, user identity card), and combined with the actual needs of various application scenarios, it is a universal eSIM card product provided for users in the human network and Internet of Things scenarios. The eSIM card in the embodiment of this application can store and manage the card data Profile in the form of a P-Slot card slot; P-Slot refers to a container for storing file systems, network access applications, card applications, etc. It can be understood that the eSIM card in the embodiment of this application may include multiple P-Slots, and the number of P-Slots it supports at the same time is specified by the relevant technical standards of the card product. Multiple P-Slots can be divided into assigned P-Slots and pre-built P-Slots based on whether the formal card resource data is configured.

[0051] Secondly, the basic functions of the pre-installed card application of the eSIM card in the embodiment of the present application are explained.

[0052] Figure 3 The application function structure diagram of the eSIM card is shown. Figure 3 As shown in the figure, the pre-installed card application refers to the application running the eSIM card, which is used to provide the user operation interface and card service processing logic required in each application scenario. The basic functions of the pre-installed card application include at least the following aspects:

[0053] Pre-set card writing management: For the unassigned P-Slot pre-built with the eSIM card, the formal network access authentication parameters are set for the P-Slot and the card is activated over the air by writing the card over the air.

[0054] Profile status synchronization: According to the relevant instructions sent by the background system, the P-Slot list and P-Slot status created by the eSIM card are reported to the background system.

[0055] Terminal and card information synchronization: According to the relevant instructions sent by the background system, obtain the terminal and card information, and copy the eSIM card related information and terminal information to the background system.

[0056] User confirmation: Provide users with an operation interface in each application scenario to meet the user confirmation requirements of the business process.

[0060] Parameter setting: Supports the card writing platform to reset parameters such as the card writing system server address or SMS service number via SMS.

[0061] Finally, the number card management system of the embodiment of the present application is described.

[0062] The number card management system in the embodiment of the present application at least includes: number management subsystem, card data management subsystem, air card writing subsystem or service set, business center, etc. Among them, the number management subsystem is used to provide number full life cycle management; the card data management subsystem is used to provide card resource basic data management, including number card data management, data rule management, etc.; the air card writing subsystem is used to implement OTA card writing function, including card writing order reception, data encryption and decryption, card writing information feedback, number activation, etc.

[0063] The number card management system in the embodiment of the present application can cooperate with the terminal side eSIM module, the core network authentication and authorization function system, the password management system and other functional units to finally form a complete number card management system. Among them, the eSIM module of the mobile terminal is used to preset temporary numbers to realize functions such as two-way authentication and key negotiation; the core network authentication and authorization function system is responsible for authentication and authorization, and realizes functions such as number activation, call connection, exchange routing, and message delivery; the password management system is responsible for the generation and management of the system's password resources, and is used to realize functions such as key generation, distribution, and full life cycle management.

[0064] Of course, the above contents regarding the eSIM card structure, its pre-set functions, number card management system, etc. are only exemplary descriptions and cannot be understood as limitations on this application.

[0065] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0066] Figure 1 A schematic diagram showing the flow of the eSIM migration method of the satellite network terminal in an embodiment of the present application is shown; Figure 1 As shown, an embodiment of the present application provides an eSIM migration method for a satellite network terminal. The migration method is implemented based on a number card management system and is applied to an eSIM data migration scenario between a first terminal and a second terminal.

[0067] For the eSIM card in the embodiment of the present application, the seed number (Active activation state) should be preset at the factory, and part of the service number data (unable unavailable state) should be preset; it can be understood that the seed number is the seed code number, which includes the eSIM card data required to establish an initial connection with the number card management system and the operator's satellite network, and each eSIM card is preset with a unique seed number at the factory; the service number is the service code number, which includes the eSIM card data required to establish a communication connection channel with the satellite network, and other data related to the eSIM service function. For example, the eSIM card in this embodiment can preset the seed number in P0-Slot and preset part of the service number data in P1-Slot, that is, the OPC, Ki, and IMSI data in the service number are not preset. When it is officially used, the unpreset data in the service number needs to be downloaded and written from the number card management system; at this time, the seed number preset in P0-Slot is unique and unchanged, and different service number data can be downloaded and written in P1-Slot. In other words, the eSIM migration method of the satellite network terminal in the embodiment of the present application supports multiple migrations of eSIM data.

[0068] In one embodiment of the present application, Figure 1 As shown, the eSIM migration method of the satellite network terminal at least includes:

[0069] Step S110: In response to an eSIM data migration request initiated by a user, a first communication connection channel is established through a seed number of an eSIM card of a first terminal.

[0070] Specifically, the first terminal is a satellite network terminal to which eSIM data is to be written, that is, a new terminal; the second terminal is a satellite network terminal to which eSIM data is to be transferred, that is, an old terminal. The satellite network terminals in this embodiment include but are not limited to computers, mobile phones, tablets and other terminal devices that implement communication functions such as surfing the Internet, answering calls, and text messages based on satellite networks. In this embodiment, the seed numbers preset in the eSIM cards of the two terminals are different, and the service number of the second terminal needs to be transferred to the eSIM card of the first terminal, so that the eSIM card of the first terminal can continue to use the original service number of the second terminal.

[0071] When there is a need for eSIM data migration, the user initiates an eSIM data migration request at the first terminal, and establishes a first communication connection channel with the air card writing subsystem through the seed number preset in the eSIM card of the first terminal. In this way, two-way authentication, information upload, and eSIM migration authorization check between the first terminal and the air card writing subsystem can be completed through the first communication connection channel.

[0072] Step S120: establishing a second communication connection channel through the service number of the eSIM card of the second terminal.

[0073] Specifically, a second communication connection channel is established with the air card writing subsystem through the service number of the eSIM card of the second terminal, and the confirmation code verification between the first terminal, the second terminal and the air card writing subsystem is completed through the first communication connection channel and the second communication connection channel respectively; that is, before the eSIM card of the first terminal is officially written, the air card writing subsystem can use the service number channel of the second terminal to send a confirmation code to it. After the user receives the confirmation code at the second terminal, the confirmation code needs to be input into the first terminal and uploaded back to the air card writing subsystem, thereby ensuring that the eSIM data migration operation of the new and old terminals is based on user authorization confirmation, thereby improving the security of eSIM migration.

[0074] Step S130: deactivate the eSIM card of the second terminal based on the second communication connection channel, and write the card data obtained through matching into the eSIM card of the first terminal through the first communication connection channel, wherein the card data corresponds to the service number of the eSIM card of the second terminal.

[0075] Specifically, in this embodiment, after completing the authentication authorization of the first terminal and the confirmation code verification of the two terminals, the eSIM card of the second terminal needs to be deactivated, that is, the service number of the eSIM card of the second terminal is deleted, and its seed number channel is retained to facilitate writing other service number data when it is used next time; thereafter, the eSIM data of the second terminal is migrated to the new eSIM card of the first terminal.

[0076] It is worth noting that the eSIM data migration scenario in the embodiment of the present application includes at least two cases: code number transfer and IMSI data transfer; code number transfer refers to migrating only the service number in the second terminal to the eSIM card of the first terminal, but not migrating the IMSI data of the second terminal, for example, the number of the eSIM card of the new terminal is the same as the number of the old terminal, but data resources are reallocated for it; IMSI data transfer refers to migrating the service number in the second terminal to the eSIM card of the first terminal, and migrating the IMSI data of the second terminal at the same time, for example, the number of the eSIM card of the new terminal is the same as the number of the old terminal, and the IMSI data of the original old terminal is also written into the eSIM card of the new terminal. It can be understood that the IMSI (International Mobile Subscriber Identification Number) in the embodiment of the present application refers to the international mobile user identity code, which is stored in the eSIM card and can be used to distinguish the valid information of the mobile user. Of course, the written data in the eSIM migration method of this embodiment includes but is not limited to IMSI data, and other data corresponding to the service number can also be written into the eSIM card of the first terminal, and this application does not limit this.

[0077] It can be seen that the eSIM migration method of the satellite network terminal in the embodiment of the present application, by respectively establishing communication connection channels between different terminals and the air card writing subsystem, enables the two terminals to cooperate with each other, and realizes the eSIM data migration between the new and old terminals on the basis of ensuring the security of eSIM migration, facilitates the update and management of eSIM cards, and meets the user's needs for data migration.

[0078] In addition, the eSIM migration method of the satellite network terminal in the embodiment of the present application can also be applied to the number change scenario of a single terminal. At this time, the seed number of the eSIM card of the single terminal is unique, and its seed number can be used to establish a communication connection channel, and then write a new service number for it; of course, the above-mentioned eSIM migration method can also be extended to scenarios such as multiple data migrations and data migration of multiple terminals, which will not be elaborated here; this application does not limit the type, function and quantity of terminal equipment.

[0079] Figure 4 The overall process diagram of eSIM data migration is shown. Figure 4 The arrows in the figure indicate the direction of data flow. Figure 4 As shown, in one embodiment of the present application, before the first terminal performs the card writing operation, the confirmation code verification of the first terminal and the second terminal is performed, and the method further includes:

[0080] Through the second communication connection channel, the air card writing subsystem of the number card management system sends a confirmation code to the second terminal, and the confirmation code is generated based on the service number of the eSIM card of the second terminal; the confirmation code received by the second terminal is input into the first terminal, and the confirmation code is uploaded to the air card writing subsystem through the first communication connection channel and the confirmation code is verified.

[0081] Specifically, the air card writing subsystem of the number card management system sends a confirmation code to the second terminal. After the user receives the confirmation code on the second terminal, he enters it into the first terminal, and uploads the confirmation code to the air card writing subsystem via the first communication connection channel established between the first terminal and the air card writing subsystem, so as to compare the sent confirmation code with the uploaded confirmation code. When the confirmation codes are consistent, it is considered to be authorized and confirmed by the same user, thereby improving the security of eSIM migration.

[0082] In one embodiment of the present application, the specific process of eSIM code number migration includes: applying for card writing data to the business center of the number card management system through the air card writing subsystem, and writing the matched card data into the eSIM card of the first terminal through the first communication connection channel, including: according to the first request of the air card writing subsystem to apply for card writing data, the business center deletes the IMSI data of the second terminal, and matches the new IMSI data corresponding to the business number in the card data management subsystem of the number card management system; in response to the business center issuing an order and triggering the air card writing operation, the new IMSI data is written into the eSIM card of the first terminal to complete the eSIM code number migration between the first terminal and the second terminal.

[0083] Specifically, the service number of the second terminal includes the first IMSI data. When the air card writing subsystem applies to the service center for the first request to write card data (e.g., a card replacement request), the service center deletes the original IMSI data of the second terminal, such as the first IMSI data, and matches the new IMSI data corresponding to the service number in the card data management subsystem of the card management system, such as the second IMSI data. The first IMSI data and the second IMSI data both point to the same service number; that is, the first terminal is assigned new second IMSI data, and the second IMSI data is written into the eSIM card of the first terminal. This implementation method is applicable to the eSIM replacement scenario. For example, when the user only wants to migrate the old number in the new terminal but does not want to keep the original IMSI data, the old card data of the service center can be directly deleted, and the new data resources can be matched in the card data management subsystem, and the code number and its corresponding second IMSI data can be written into the eSIM card of the new terminal, thereby making the numbers of the new and old terminals the same, and realizing the eSIM code number transfer function of different terminals.

[0084] In another embodiment of the present application, the specific process of eSIM card data migration includes: applying for card writing data to the business center of the number card management system through the air card writing subsystem, and writing the matched card data into the eSIM card of the first terminal through the first communication connection channel includes: according to the second request of the air card writing subsystem to apply for card writing data, the business center queries the IMSI data of the second terminal; in response to the air card writing operation issued by the business center and triggered by the order, the IMSI data of the second terminal obtained by the query is written into the eSIM card of the first terminal to complete the IMSI data migration between the first terminal and the second terminal.

[0085] Specifically, the service number of the second terminal includes the original IMSI data. When the air card writing subsystem applies to the service center for a second request to write card data (such as a code number and card data migration request), it is necessary to query the original IMSI data corresponding to the service number of the second terminal, and write the service number and its corresponding original IMSI data together into the eSIM card of the first terminal. This implementation method is applicable to the IMSI data migration scenario of eSIM. For example, when a user wants to migrate the old number to the new terminal and retain the original IMSI data, the service number of the second terminal can be used to directly query the old card data in the system and write it into the eSIM card of the new terminal, thereby making the numbers of the new and old terminals the same and the card data resources the same, thus realizing the IMSI data transfer function of different terminals.

[0086] Figure 5This is a business process diagram for eSIM data migration, which mainly includes: requesting eSIM migration, receiving confirmation code, deleting the second terminal number, applying for card data writing and placing an order, air card writing operation, activating the new number of the first terminal, deactivating the seed number of the first terminal, etc. Figure 5 As shown, in some embodiments of the present application, the deactivation of the eSIM card of the second terminal based on the second communication connection channel includes: deleting the service number of the eSIM card of the second terminal and activating the seed number of the eSIM card of the second terminal according to the confirmation code verification success instruction issued by the air card writing subsystem; establishing a third communication connection channel through the seed number of the eSIM card of the second terminal, sending a network notification through the third communication connection channel, and updating the code number status of the eSIM card of the second terminal in the air card writing subsystem.

[0087] Specifically, since only one of the seed number connection channel and the service number connection channel of each eSIM card needs to be retained, before the eSIM card of the first terminal is officially used, it is necessary to delete the service number of the eSIM card of the second terminal according to the confirmation code verification success instruction issued by the air card writing subsystem to avoid abnormal situations caused by the simultaneous existence of two service numbers and ensure that the service number can be smoothly written into the first terminal; at the same time, it is necessary to activate the seed number of the eSIM card of the second terminal so as to establish a third communication connection channel through the seed number of the eSIM card of the second terminal, send a network notification through the third communication connection channel, and update the code number status of the eSIM card of the second terminal in the air card writing subsystem, at which time the eSIM card of the second terminal is deactivated; in addition, when the second terminal has the need to use it again, the seed number of the second terminal can also be used to establish a communication connection channel and write other service numbers, thereby saving eSIM resources and reducing usage costs.

[0088] In some embodiments of the present application, after the first terminal performs a card writing operation, the method further includes: activating the service number of the eSIM card of the first terminal and deactivating the seed number of the eSIM card of the first terminal according to an activation new number instruction issued by the air card writing subsystem; establishing a fourth communication connection channel through the service number of the eSIM card of the first terminal; restarting the first terminal, sending a network notification through the fourth communication connection channel, and updating the code number status of the eSIM card of the first terminal in the air card writing subsystem.

[0089] Specifically, before the first terminal performs the card writing operation, it needs to establish a first communication connection channel through the seed number of the eSIM card and implement operations such as authentication and confirmation; after the first terminal successfully writes the card, according to the activation new number instruction issued by the air card writing subsystem, the service number of the eSIM card of the first terminal is activated and the seed number of the eSIM card of the first terminal is deactivated; then the service number is used to establish a fourth communication connection channel; restart the first terminal, send a network notification through the fourth communication connection channel, and update the code number status of the eSIM card of the first terminal in the air card writing subsystem, at which time the eSIM card of the first terminal is officially put into use. It can be seen that the embodiment of the present application enables the two terminals to cooperate with each other by respectively establishing communication connection channels between different terminals and the air card writing subsystem, which not only realizes the eSIM data migration between the new and old terminals, but also facilitates the data update and management of the eSIM card.

[0090] In one embodiment of the present application, continue to refer to Figure 5 As shown, before the first terminal and the second terminal perform confirmation code verification, the method also includes: obtaining the eSIM card information of the first terminal; establishing a BIP link channel with the air card writing subsystem through the seed number of the eSIM card of the first terminal; according to the MSISDN number input by the user to the first terminal, uploading the EID information and TAC information of the first terminal to the air card writing subsystem through the BIP link channel, completing the two-way authentication between the first terminal and the air card writing subsystem, and querying the eSIM migration authority.

[0091] The eSIM card information of the first terminal includes a preset seed number and part of the service number information. In this embodiment, an air link is established with the card writing platform through the BIP method, that is, a BIP link channel is established through the seed number of the eSIM card of the first terminal to provide an air card writing operation environment. Specifically, the MSISDN number (Mobile Subscriber International ISDN / PSTN number) refers to the number that the calling user needs to dial to call a mobile user, such as a mobile phone number; the EID information and TAC information are the information carried in the terminal eSIM. That is to say, in this embodiment, the user needs to enter the original MSISDN number in the first terminal, and based on the input, the upload operation of the eSIM information is triggered, and the EID information and TAC information of the first terminal are uploaded to the air card writing subsystem through the BIP link channel, thereby completing the two-way authentication between the first terminal and the air card writing subsystem, and querying the eSIM migration authority; when the authentication and authority confirmation are successful, subsequent operations are performed to further ensure the security and stability of eSIM data migration.

[0092] In some embodiments, the air card writing subsystem includes an authorization and authentication module and an air card writing module. The authorization and authentication module of the air card writing subsystem is used to complete the authentication and confirmation of the first terminal, and the air card writing process of the first terminal is completed through the air card writing module in the air card writing subsystem.

[0093] Preferably, combined Figure 4 and Figure 5 As shown, the specific process of the eSIM migration method of the satellite network terminal in the embodiment of the present application is as follows:

[0094] 1) eSIM migration, authorization and authentication: In response to the eSIM data migration request initiated by the user, the eSIM card information of the first terminal is obtained; a BIP link channel is established with the air card writing subsystem through the seed number of the eSIM card of the first terminal, and two-way authentication is performed.

[0095] 2) eSIM migration request: According to the MSISDN number input by the user to the first terminal, the EID information and TAC information of the first terminal are uploaded to the air card writing subsystem through the BIP link channel, and the eSIM migration authority is queried.

[0096] 3) Sending a confirmation code: Through the second communication connection channel, the air card writing subsystem of the number card management system sends a confirmation code to the second terminal, and the confirmation code is generated based on the service number of the eSIM card of the second terminal.

[0097] 4) Upload confirmation code: input the confirmation code received by the second terminal into the first terminal, and upload the confirmation code to the air card writing subsystem through the first communication connection channel and perform confirmation code verification.

[0098] 5) The old terminal deletes the service number and activates the seed number: according to the confirmation code verification success instruction issued by the air card writing subsystem, deletes the service number of the eSIM card of the second terminal and activates the seed number of the eSIM card of the second terminal; establishes a third communication connection channel through the seed number of the eSIM card of the second terminal, sends a network notification through the third communication connection channel, and updates the code number status of the eSIM card of the second terminal in the air card writing subsystem.

[0099] 6) Deleting / querying old data and requesting new card writing data: According to the first request / second request of the air card writing subsystem for applying for card writing data, the service center deletes / queries the IMSI data of the second terminal.

[0100] 7) Matching IMSI data: matching the IMSI data corresponding to the service number in the card data management subsystem of the number card management system; responding to the service center issuing an order and triggering an over-the-air card writing operation so that the corresponding IMSI data is written into the eSIM card of the first terminal.

[0101] 8) Authorization of card writing data resources: Based on the instruction of successful card writing resource matching, the card data management subsystem performs the card writing data resource authorization operation on the air card writing subsystem to ensure that it has the authority to perform air card writing operations.

[0102] 9) Over-the-air card writing process: The corresponding IMSI data obtained through matching by the card data management subsystem is written into the eSIM card of the first terminal via the over-the-air card writing module.

[0103] 10) New account application: Submit a new account application, and the new account information will be reviewed by the business center and the authorization and authentication module of the air card writing subsystem. After the new account application is confirmed to be correct, the air card writing module of the air card writing subsystem will trigger the activation of the new number instruction.

[0104] 11) Activate the service number and deactivate the seed number of the new terminal: according to the activation new number instruction issued by the air card writing subsystem, activate the service number of the eSIM card of the first terminal and deactivate the seed number of the eSIM card of the first terminal; establish a fourth communication connection channel through the service number of the eSIM card of the first terminal.

[0105] 12) New terminal restart and network notification: After the new number is activated, the first terminal is restarted, a network notification is sent through the fourth communication connection channel, and the code number status of the eSIM card of the first terminal in the air card writing subsystem is updated.

[0106] Therefore, not only the eSIM data migration of the new and old terminals is realized, but also the security and reliability of data transmission are ensured; in addition, relevant technicians in this field can adjust or improve the content and sequence of the above steps in combination with specific scenarios, which will not be repeated here. Of course, the above migration steps are only for the convenience of understanding and simplified description, and cannot be understood as a limitation of this application.

[0107] In some preferred embodiments of the present application, the eSIM migration method of the satellite network terminal also includes an abnormal rollback process, which specifically includes: determining whether there is an abnormality in the eSIM migration process of the first terminal and the second terminal, and the abnormality includes at least one or more of two-way authentication failure, confirmation code verification failure, air card writing failure, and new number network failure; if there is an abnormality in the eSIM migration process, restart the rollback process of the eSIM migration and report the processing result of the abnormality. Specifically, the following abnormalities may be included:

[0108] In case 1, when the two-way authentication between the first terminal and the air card writing subsystem fails, the terminal user restarts the two-way authentication process. After multiple failed restarts, the processing results of the two-way authentication failure are reported for assistance from customer service / technical personnel; conversely, if the two-way authentication is successful after the restart, the subsequent eSIM migration process continues.

[0109] In the second case, when the second terminal does not receive the confirmation code, the terminal user restarts the second terminal. If the second terminal still does not receive the confirmation code at this time, the confirmation code issuance process is restarted. After multiple restart failures, the processing result of the confirmation code verification failure is reported for customer service / technical assistance. On the contrary, if the second terminal receives the confirmation code successfully after the restart, the subsequent eSIM migration process continues.

[0110] Case 3: During the process of performing the air card writing operation on the first terminal, when the first terminal is disconnected from the air card writing subsystem or the installation fails, the card writing data is downloaded again. After repeated download failures, the processing result of the air card writing failure is reported. This situation may be caused by the business center deleting the card writing data. In this case, customer service / technical personnel can assist in handling it; conversely, if the air card writing is successful after re-downloading, the subsequent eSIM migration process continues;

[0111] Case 4: When the new number of the first terminal fails to be registered on the network, the first terminal is restarted. If the new number still fails to be registered on the network at this time, the result of the failure to be registered is reported. This situation may be caused by the air card writing subsystem canceling the air card writing task, or it may be caused by the business center deleting the card writing data. At this time, customer service / technicians can assist in handling it; conversely, if the new number is successfully registered on the network after restarting the terminal, the subsequent eSIM migration process will continue.

[0112] Of course, the above abnormal situations are merely exemplary embodiments and should not be construed as limitations on the present application.

[0113] In summary, this application has achieved at least the following technical effects:

[0114] First, by establishing communication connection channels between different terminals and the air card writing subsystem, the two terminals can cooperate with each other, realizing the eSIM data migration between the new and old terminals. It has strong compatibility and a wide range of applications, which is conducive to the update and management of eSIM cards.

[0115] Second, two-way authentication is performed on the new terminal, and confirmation code verification is implemented between the two terminals through different communication connection channels, ensuring that only legitimate users can perform eSIM data migration, improving the stability and security of the eSIM data migration process, and protecting user privacy and data security;

[0116] Third, by setting up the abnormal rollback process of eSIM data migration, comprehensive and effective handling measures are provided for abnormal situations such as failure of two-way authentication, failure of confirmation code verification, failure of air card writing, failure of new number registration, etc. At the same time, based on the feedback of abnormal handling results, it can help relevant technical personnel to promptly discover potential technical loopholes in the system, so as to facilitate system maintenance and upgrades, ensure the quality and efficiency of eSIM data migration, and further improve the user experience.
