[0038] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0039] For existing SIM card terminal devices, when replacing the terminal device, the SIM card needs to be pulled out from the original terminal device and inserted into the new terminal device for use. However, the eUICC card of the eSIM terminal device cannot be pulled out. The eSIM profile in the eUICC card is associated with the eUICC chip identifier (eUICC identification, EID) of the original terminal device and cannot be read or copied. According to the existing eSIM standards and procedures, when replacing the terminal device, the user must apply for the eSIM card replacement service from the operator and provide the EID of the new eSIM terminal device to the operator. The operator then generates a new eSIM profile for the new EID, and the user's phone number remains unchanged. After generating the eSIM profile, a QR code for downloading the eSIM profile is generated. The user uses the new terminal to scan the QR code and download the new eSIM profile to the new eUICC. The main process of replacing the eSIM card includes:

[0040] (1) The user brings a new eSIM terminal device to the operator's business hall and goes to the service counter to apply to migrate the user number used by the original eSIM terminal device to the new eSIM terminal device. (2) The user provides the counter attendant with the EID of the new eSIM terminal. (3) Wait for the attendant to process the eSIM card number migration request. (4) After the operator system completes the migration request, it prints the activation code of the newly generated eSIM profile. (5) The user uses the new eSIM terminal to scan the activation code and download the eSIM profile. The eSIM card replacement has the following disadvantages: the card replacement process is an offline process, which is relatively complicated and cumbersome, time-consuming, and has a poor experience. It also increases the operator's offline service operating costs. In order to solve the above technical problems, the embodiments of the present application provide the following solutions.

[0041] See Figure 1 , Figure 1This is a schematic diagram of the architecture of an eSIM card replacement system provided in an embodiment of the present application. The eSIM card replacement system includes a terminal device 101, an authentication server (ES) 102, an operator business support system (BSS) 103, and an eSIM server 104. The terminal device 101 can be a cellular phone, a smart phone, a portable computer, a handheld communication device, a handheld computing device, a satellite radio device, a global positioning system, a personal digital assistant (PDA), and / or any other suitable device for communicating on a wireless communication system. The authentication server 102 can be a server deployed and maintained by the operator, or a server deployed and maintained by the terminal manufacturer, and is used to verify the user identity of the terminal device. The operator business support system 103 is a backend support system for resources (networks, equipment, computer systems), including a professional network management system, a resource management system, a professional activation system, a service assurance system, etc., providing support means for reliable, secure and stable operation of the network. The eSIM server 104 can be a subscription manager-data preparation plus server (SM-DP+), which can be used to generate an eSIM profile and provide it to the terminal device for download. Optionally, the eSIM card replacement system can also include a cloud server and other terminal devices.

[0042] Another example Figure 2 As shown, Figure 2 This is a schematic diagram of the architecture of a software system provided in an embodiment of the present application. The software system includes an eSIM server, an ES, and a terminal device. The terminal device may include: a backup, recovery, and cloning module, an authorization client module, an operator authentication module, an eSIM card replacement module, an eSIM local profile download module (LPD), an eSIM local user interface (LUI), an eSIM local profile assistant (LPA) service module, and an eUICC. The interface between the ES, the eSIM server, and the LPD of the terminal device is used to provide a secure data transmission channel.

[0043] like Figure 3 As shown, Figure 3 This is a flowchart of an eSIM card replacement method provided in an embodiment of the present application. The steps in the embodiment of the present application at least include:

[0044] S301: The terminal device obtains the user account, eUICC chip identifier, password, and user number.

[0045] In a specific implementation, the terminal device can log in to the cloud server and send a recovery request to the cloud server. After receiving the recovery request, the cloud server returns multiple user numbers, and the terminal device selects the user number to be restored from the multiple user numbers. Alternatively, the terminal device can receive the user number entered by the user. Alternatively, the terminal device can select the content to be copied and send a copy request to other terminal devices (such as the original terminal device). After receiving the copy request, the other terminal device returns the copied content. This cloning method is used to migrate user numbers online from other terminal devices. The user number is the user's mobile phone number (mobile station international subscriber directory number, MSISDN), and the user number can be the user number used by the original terminal device. In addition, the terminal device can receive the user account and password entered by the user, wherein the user account can be an account registered by the user, which can be an email address, user name or mobile phone number, etc. The terminal device can obtain the EID from the configuration information, wherein the EID can be a serial number.

[0046] S302: The terminal device sends a first card replacement request to the ES, and the ES receives the first card replacement request sent by the terminal device, wherein the first card replacement request includes a user account, password, user number, and the EID of the terminal device.

[0047] S303, the ES verifies the user identity of the terminal device based on the user account and password.

[0048] In a specific implementation, the ES can determine whether the received user account and password are the same as the pre-stored user account and password. If they are, verification succeeds and S304 is executed. If they are not, verification fails. In this case, the ES can send a verification failure message to the terminal device, prompting the user to re-enter the user account and password and re-execute S301. If the number of times the user re-enters the user account and password exceeds a preset threshold, a prohibition message can be sent to the terminal device. This prohibition message is used to instruct the terminal device to prohibit the user from entering the user account and password for a period of time. The preset threshold can be 3 or 4, for example.

[0049] S304: The ES sends a second card replacement request to the BSS. The second card replacement request may include the user number and the EID of the terminal device. The second card replacement request may also include the user account, password, user number, and the EID of the terminal device. After receiving the second card replacement request sent by the ES, the BSS retains the user number and generates new eSIM card data. It binds the user number to the generated eSIM card data to complete the eSIM card replacement, so that the terminal device can use the original user number for communication services. The eSIM card data may include, for example, an integrated circuit card identity (ICCID).

[0050] Optionally, the BSS may also verify the user identity of the terminal device according to the user account and password. If the verification is successful, S305 is executed. If the verification fails, the verification may be repeated according to the step of S303.

[0051] S305: The BSS sends a notification message to the eSIM server. The eSIM server receives the notification message sent by the BSS. The notification message includes the EID of the terminal device and may also include the generated eSIM card data.

[0052] S306: The eSIM server may generate an eSIM configuration file based on the eSIM card data and associate the eSIM configuration file with the EID, wherein the eSIM configuration file is a new eSIM configuration file generated when the terminal device accesses the network.

[0053] S307: The eSIM server sends a response message to the BSS. The BSS receives the response message sent by the eSIM server, which indicates that the eSIM configuration file has been prepared.

[0054] S308: The BSS sends a card replacement completion notification to the ES. The ES receives the card replacement completion notification sent by the BSS, which includes an activation code.

[0055] S309: The ES sends a card replacement success notification to the terminal device. The terminal device receives the card replacement success notification sent by the ES, which includes an activation code.

[0056] S310: The terminal device downloads the eSIM configuration file from the eSIM server.

[0057] In the specific implementation, after the terminal device receives the card replacement success notification sent by the ES, it can send a download request carrying the EID of the terminal device to the eSIM server. After receiving the download request, the eSIM server can obtain the eSIM configuration file associated with the EID based on the EID of the terminal device, and send the eSIM configuration file to the terminal device.

[0058] S311, after receiving the eSIM configuration file, the terminal device uses the activation code to activate the eSIM configuration file, so that the terminal device can access the network for communication.

[0059] In an embodiment of the present application, a terminal device can send a card replacement request to the ES. After completing authentication, the ES sends the card replacement request to the BSS. The BSS notifies the eSIM server to generate an eSIM configuration file and associate the eSIM configuration file with the EID. In this way, the terminal device can download the eSIM configuration file from the eSIM server. After activating the eSIM configuration file, it can use the original user number for communication. All eSIM card replacement processes can be completed online, and eSIM activation is completed automatically, simplifying the operation process of eSIM card replacement and improving the efficiency of eSIM card replacement.
