[0036] The embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0037] 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 identification (EID) of the original terminal device and cannot be read and copied. According to the existing eSIM standards and processes, when replacing the terminal device, the user must apply for an eSIM card replacement service from the operator and provide the EID of the new eSIM terminal device to the operator. Then, the operator generates a new eSIM profile for the new EID, and the user's phone number remains unchanged. After generating the eSIM profile, a two-dimensional code for downloading the eSIM profile is generated, and the user uses the new terminal to scan the two-dimensional code to download the new eSIM profile to the new eUICC. The main processes for replacing the eSIM card include:

[0038] (1) The user brings the new eSIM terminal device to the operator's business hall and applies at the service counter to migrate the user number used by the original eSIM terminal device to the new eSIM terminal device. (2) The user provides the EID of the new eSIM terminal to the counter staff. (3) Wait for the staff to process the eSIM card number migration request. (4) After the operator's system finishes processing the migration request, print 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. This eSIM card replacement has the following disadvantages: The card replacement process is an offline process, which is relatively complex and cumbersome, time-consuming, and has a poor experience. Moreover, it increases the operator's offline service operation cost. To solve the above technical problems, the embodiments of the present application provide the following solutions.

[0039] Please refer to Figure 1 , Figure 1 which is a schematic architecture diagram of an eSIM card replacement system provided by the embodiments of the present application. The eSIM card replacement system includes a terminal device 101, an entitlement server (ES) 102, a business support systems (BSS) 103 of the operator, 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 the wireless communication system 100, etc. 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 service management system 103 is a back-end support system for resources (networks, devices, computer systems), including a professional network management system, a resource management system, a professional activation system, a service guarantee system, etc., and provides support means for the reliable, secure, and stable operation of the network. The eSIM server 104 can be a subscription manager-data preparationplus server (SM-DP+), and can be used to generate an eSIM Profile and provide it for the terminal device to download. Optionally, the eSIM card replacement system may further include a cloud server and other terminal devices.

[0040] Another example Figure 2 is shown as Figure 2It is a schematic diagram of the architecture of a software system provided by an embodiment of the present application. The software system includes an eSIM server, an ES, and a terminal device. Among them, the terminal device may include: a backup recovery cloning module, an authorization client module, an operator authentication module, an eSIM card replacement module, an eSIM local profile download module (local profile download, LPD), an eSIM local user interface (local user interface, LUI), an eSIM local profile assistant (local profile assistant, LPA) service module, and an eUICC. Among them, the interface between the ES, the eSIM server, and the LPD of the terminal device is used to provide a secure data transmission channel.

[0041] As Figure 3 shown, Figure 3 It is a schematic flowchart of an eSIM card replacement method provided by an embodiment of the present application. The steps in the embodiment of the present application at least include:

[0042] S301, the terminal device obtains a user account, an eUICC chip identifier, a password, and a user number.

[0043] 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 recovered from the multiple user numbers. Alternatively, the terminal device can receive the user number input by the user. Alternatively, the terminal device can select the content to be copied, send a copy request to other terminal devices (such as the original terminal device), and after receiving the copy request, the other terminal device returns the copied content. The user number is migrated online from other terminal devices through this cloning method. Among them, 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 input by the user. Among them, the user account can be the account registered by the user, which can be an email, a username, a mobile phone number, etc. The terminal device can obtain the EID from the configuration information, where the EID can be a serial number.

[0044] 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. The first card replacement request includes a user account, a password, a user number, and the EID of the terminal device.

[0045] S303, the ES verifies the user identity of the terminal device according to the user account and password.

[0046] In a specific implementation, the ES can determine whether the received user account and password are the same as the pre - saved user account and password. If they are the same, the verification passes and S304 is executed. If they are different, the verification fails. In this case, the ES can send a verification - failed 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. The 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. Among them, the preset threshold can be 3, 4, etc.

[0047] S304, the ES sends a second SIM - card replacement request to the BSS. Among them, the second SIM - card replacement request can include the user number and the EID of the terminal device. The second SIM - card replacement request can also include the user account, password, user number, and the EID of the terminal device. After receiving the second SIM - card replacement request sent by the ES, the BSS retains the user number, generates new eSIM card data, binds the user number to the generated eSIM card data, and completes the eSIM card replacement so that the terminal device can use the original user number for communication services. Among them, the eSIM card data can include the integrate circuit card identity (ICCID), etc.

[0048] Optionally, the BSS can also verify the user identity of the terminal device according to the user account and password. If the verification passes, S305 is executed. If the verification fails, the verification can be re - performed according to the steps of S303.

[0049] 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 can also include the generated eSIM card data.

[0050] S306, the eSIM server can generate an eSIM configuration file according to the eSIM card data and associate the eSIM configuration file with the EID. Among them, the eSIM configuration file is a new eSIM configuration file regenerated for the terminal device to access the network.

[0051] S307, the eSIM server sends a response message to the BSS. The BSS receives the response message sent by the eSIM server. The response message is used to indicate that the eSIM configuration file has been prepared.

[0052] S308, the BSS sends a SIM - card replacement completion notice to the ES. The ES receives the SIM - card replacement completion notice sent by the BSS. The SIM - card replacement completion notice includes an activation code.

[0053] S309, the ES sends a successful SIM card replacement notification to the terminal device. The terminal device receives the successful SIM card replacement notification sent by the ES, and the successful SIM card replacement notification includes an activation code.

[0054] S310, the terminal device downloads the eSIM configuration file from the eSIM server.

[0055] In a specific implementation, after the terminal device receives the successful SIM card replacement 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 according to the EID of the terminal device, and send the eSIM configuration file to the terminal device.

[0056] S311, after the terminal device receives the eSIM configuration file, it activates the eSIM configuration file using the activation code, so that the terminal device can access the network for communication.

[0057] In the embodiments of the present application, the terminal device can send a SIM card replacement request to the ES. After the ES completes the authentication, it sends a SIM card replacement request to the BSS. The BSS notifies the eSIM server to generate the eSIM configuration file and associates 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 the processes of eSIM SIM card replacement can be completed online, and eSIM activation is automatically completed, simplifying the operation process of eSIM SIM card replacement and improving the efficiency of eSIM SIM card replacement.
