Technical Field

[0001] The present application relates to the field of vehicle testing technology, and in particular to an eSIM card code information switching system and method. Background Art

[0002] When domestic vehicles are prepared to be exported to the target sales country, since the vehicles may need to be produced in overseas factories (and the country where the factory is located is usually not the same as the target sales country), in order to ensure that the SIM card on the vehicle can be connected normally and use data traffic and other functions, the vehicle needs to conduct relevant tests on traffic usage costs during the domestic R&D stage, overseas production and assembly stage, and overseas vehicle sales stage.

[0003] The existing technical means is to directly use the overseas operator code resources pre-installed in the eSIM, which is the so-called "seed number", to simulate the traffic usage of the SIM card in the actual use scenario of the vehicle overseas through the roaming function to detect whether its connectivity is good and whether it can meet the requirements of use in the target sales country. In this way, possible SIM card-related problems can be discovered and solved in advance, ensuring that the vehicle can smoothly realize related communication and networking functions after export.

[0004] However, the traffic charges for roaming by operators in overseas target sales countries to the corresponding countries of domestic R&D or overseas factories are very expensive.

[0051] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0052] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0053] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0054] Based on this, the embodiment of the present application provides an eSIM card code information switching system, referring to Figure 1 , Figure 1 This is a functional module diagram provided for Example 1 of the eSIM card code information switching system of the present application.

[0055] In this embodiment, the eSIM card number information switching system includes: an Internet of Vehicles platform 10, a number management platform 20, an operator eSIM management platform 30 and an eSIM module 40;

[0056] The number management platform 20 is used to determine the operator roaming data of the export target country of the export vehicle from the Internet of Vehicles platform 10 according to the triggered number information switching request.

[0057] It should be noted that the eSIM card (Embedded-SIM) is a SIM card embedded in export vehicles. The vehicle can connect normally and use data traffic and other functions through the eSIM card.

[0058] It should be noted that the Internet of Vehicles platform is an information management platform for exported vehicles, which provides the vehicle identification number (VIN), vehicle tbox number, vehicle SIM card three-code information, SIM card target country name and operator name information, etc.

[0059] The number management platform is a platform for managing the eSIM card numbers. It supports the configuration of the operator information and traffic cost information of the eSIM card for export vehicles. When the eSIM card number information needs to be switched, the number resource information to be switched (such as the above three-code information, operator information, etc.) will be notified to the operator's eSIM management platform to switch the eSIM card number.

[0060] It should be noted that the code number information switching request is a request to switch the eSIM card code number when a traffic test is required when the vehicle is in the domestic research and development stage, overseas production and assembly stage, overseas vehicle sales stage, etc.

[0061] Among them, the export target country is the country to which the exported vehicles will be exported.

[0062] It should be noted that operator roaming data refers to the data usage generated when the eSIM card data roams to the network coverage area of ​​the export target country.

[0063] Among them, the operator roaming data may include operator information of the export target country, the cost per M of traffic of different operators roaming to the location of the eSIM card, etc., which is not limited in this embodiment.

[0064] In a feasible implementation manner, the operator roaming data described in this embodiment includes an operator list and a roaming cost list; the number management platform 20 is also used to generate an information acquisition instruction when triggering a number information switching request for an export vehicle, and send the information acquisition instruction to the Internet of Vehicles platform 10; the Internet of Vehicles platform 10 is also used to send the operator information of the export target country of the export vehicle to the number management platform 20 according to the information acquisition instruction; the number management platform 20 is also used to obtain the operator information list and roaming cost list of the export target country based on the operator information.

[0065] It should be noted that the information acquisition instruction is an instruction generated by the number management platform to obtain the number resource information to be switched (such as the above three-code information, operator information, etc.) from the Internet of Vehicles platform.

[0066] It should be noted that the operator list is a list of operator information of telecommunication services stored in the Internet of Vehicles platform, wherein the operator list includes operator information of multiple countries, and each country includes information of multiple different operators. The information of multiple different operators in the export target country can be determined based on the operator list.

[0067] The roaming cost list is a detailed breakdown of the costs incurred when using roaming services under different circumstances, such as data traffic charges, call charges, and other specific cost information when roaming to the export target country from different regions during the domestic R&D stage, overseas production and assembly stage, and overseas vehicle sales stage.

[0068] Through the roaming cost list, the specific circumstances of various fees when export vehicles use roaming services at different stages can be clearly understood, so as to select the most appropriate eSIM card code number.

[0069] Specifically, when the code information switching request of the export vehicle is triggered, the code management platform obtains the operator information O1 of the export target country of the export vehicle from the Internet of Vehicles platform, and then obtains the operator information list of multiple countries that can be associated for testing (O2, O3, O4, etc.) and the roaming cost list per M of traffic roaming to the location of the eSIM card (C2, C3, C4, etc.) through the operator information O1.

[0070] In this implementation manner, by obtaining the operator list and roaming cost list, the specific circumstances of various fees for export vehicles using roaming services at different stages can be clarified so as to select the most appropriate operator.

[0071] The number management platform 20 is further used to determine the target operator according to the operator roaming data, and send the number issuance notification and the number resources to be switched to the operator eSIM management platform 30 corresponding to the target operator.

[0072] It should be noted that the target operator is the most suitable telecommunications operator (for example, the one with the lowest data traffic fee, the lowest call fee, etc.) selected based on the above operator list and roaming cost list.

[0073] The code number issuance notification is a notification of issuing the code number resources to be switched after the target operator is determined. The code number resources to be switched are the resources that the eSIM card of the export vehicle needs to switch information, such as the above three code information, operator information, etc.

[0074] It should be noted that the operator's eSIM management platform is a management platform used to send the information of code resources to be switched to exported vehicles when the vehicle is in various stages, such as the domestic research and development stage, overseas production and assembly stage, and overseas vehicle sales stage.

[0075] In a feasible implementation manner, the number management platform 20 described in this embodiment is also used to determine the address of the location of the exported vehicle at different stages, and the different stages include the vehicle research and development stage, the production and assembly stage, and the vehicle sales stage; the number management platform 20 is also used to determine the minimum value of the roaming traffic cost between the address and the export target country based on the roaming cost list; the number management platform 20 is also used to determine the target operator from the operator information list based on the minimum value.

[0076] It should be noted that the vehicle R&D stage is the period of design, technology development, engineering verification and other work for export vehicles. The production and assembly stage is the process of putting the completed design into practice, manufacturing and assembling various parts to form a complete vehicle. The vehicle sales stage is the process of bringing the produced vehicles to the market and selling them to end consumers through various sales channels and methods, such as dealer networks, online platforms, etc.

[0077] At each of the above stages, the connectivity of the eSIM cards of exported vehicles needs to be tested to ensure the quality of the produced vehicles.

[0078] Specifically, after obtaining the above-mentioned operator list and roaming cost list, according to the addresses at different stages, the number management platform can obtain the minimum cost Cx and its corresponding target operator Ox in the roaming cost list (C2, C3, C4, etc.), and set Ox as the target operator.

[0079] In this implementation, by determining the traffic usage costs of export vehicles in the domestic R&D stage, overseas production and assembly stage, and overseas vehicle sales stage, the cost of eSIM card connectivity at different stages can be reduced.

[0080] The operator's eSIM management platform 30 is used to send the code number resource to be switched to the eSIM module 40 of the export vehicle according to the code number issuance notification.

[0081] The eSIM module 40 is used to download the code number resource to be switched to replace the original preset code number.

[0082] It should be noted that the eSIM module uses the eSIM card to remotely configure and manage user network connection information and other information. The eSIM module can be used to conveniently switch operators.

[0083] The original preset code number is the code number preset by default in the current period of the eSIM card of the eSIM module.

[0084] The eSIM module supports the operator's eSIM management platform to remotely send code resources to the eSIM module. The eSIM module can download the code resources of the eSIM card to the module to replace the default preset code and complete the over-the-air number writing.

[0085] In this implementation, through the eSIM module, the operator switching of the eSIM can be conveniently achieved based on the number resources remotely issued by the operator's eSIM management platform.

[0086] In the technical solution provided in this embodiment, a system for switching the code number information of an eSIM card is proposed, and the system includes: an Internet of Vehicles platform, a code number management platform, an operator eSIM management platform, and an eSIM module; when the code number information switching request of an export vehicle is triggered, the code number management platform obtains the operator information O1 of the export target country of the export vehicle from the Internet of Vehicles platform, and then obtains the operator information list (O2, O3, O4, etc.) of multiple countries that can be associated and tested and the roaming cost list (C2, C3, C4, etc.) of each M flow roaming to the location of the eSIM card through the operator information O1. Then, according to the address at different stages, the code number management platform can obtain the minimum cost Cx and its corresponding target operator Ox in the roaming cost list (C2, C3, C4, etc.), and set Ox as the target operator, and send the code number issuance notification and the code number resources to be switched to the operator eSIM management platform corresponding to the target operator. The operator's eSIM management platform is used to send the code number resource to be switched to the eSIM module of the export vehicle according to the code number notification; the eSIM module is used to download the code number resource to be switched to replace the original preset code number. Since this embodiment configures the operator's roaming data of the export vehicle through code number management to switch the code number resource to be switched of the operator's eSIM management platform and write it to the eSIM module, the lowest cost of export vehicle traffic can be achieved, effectively reducing the traffic usage cost of export vehicles in the domestic research and development stage, overseas production and assembly stage, and overseas vehicle sales stage.

[0087] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 2 , Figure 2 This is a system architecture diagram provided for Example 2 of the eSIM card code information switching system of this application.

[0088] The operator eSIM management platform 30 described in this example includes a test period operator eSIM management platform; when the export vehicle is in the vehicle research and development stage or the production and assembly stage, the number management platform 20 is also used to send the number issuance notification and the number resources to be switched to the test period operator eSIM management platform corresponding to the target operator; the test period operator eSIM management platform is used to send the number resources to be switched to the eSIM module 40 of the export vehicle for air number writing according to the number issuance notification; the eSIM module 40 is also used to replace the original preset number with the number resources to be switched for traffic testing.

[0089] It should be noted that the operator's eSIM management platform during the testing period is a management platform that sends the code resource information to be switched to the export vehicle for traffic testing during the vehicle testing period (i.e. the vehicle research and development stage, the production and assembly stage).

[0090] For ease of understanding, for example Figure 2 As shown, when the export vehicle is in the vehicle research and development stage or the production and assembly stage, the code number management platform (i.e., the export vehicle SIM card code number management cloud platform) obtains the target country and operator information of the export vehicle from the Internet of Vehicles platform (i.e., the export vehicle Internet of Vehicles cloud platform). Then the export vehicle SIM card code number management cloud platform sends the code number issuance notification to the test period operator eSIM management platform (for example, A2 country operator, B2 country operator, C2 country operator, etc.). The test period operator eSIM management platform writes the number of the eSIM module of the vehicle-mounted TBOX in the air according to the code number resources to be switched. The eSIM module replaces the original preset code number with the code number resources to be switched for traffic testing, and completes the manual test traffic.

[0091] In this implementation, traffic testing with the lowest traffic cost during the vehicle development and production assembly stages can be achieved through the trial operator's eSIM management platform.

[0092] Furthermore, the operator eSIM management platform 30 described in this example also includes an eSIM management platform of the operator in the target country; when the export vehicle is in the vehicle sales stage, the number management platform 20 is also used to send the number issuance notification and the number resources to be switched to the target country operator eSIM management platform corresponding to the target operator; the target country operator eSIM management platform is used to send the number resources to be switched to the eSIM module 40 of the export vehicle for air number writing according to the number issuance notification; the eSIM module 40 is also used to replace the original preset number with the number resources to be switched for vehicle networking.

[0093] It should be noted that the eSIM management platform of the operator in the target country is the management platform that sends the information of the code resources to be switched to the export vehicles for networking during the vehicle sales stage.

[0094] For ease of understanding, for example Figure 2As shown, when the export vehicle is in the vehicle sales stage, the export vehicle SIM card number management cloud platform obtains the target country and operator information of the export vehicle from the export vehicle Internet of Vehicles cloud platform. Then the export vehicle SIM card number management cloud platform sends the code number issuance notification to the target country operator eSIM management platform (for example, A2 country operator, B2 country operator, C2 country operator, etc.). The target country operator eSIM management platform writes the number of the eSIM module of the vehicle-mounted TBOX in the air according to the code number resources to be switched. The eSIM module replaces the original preset code number with the code number resources to be switched to complete the vehicle networking use. Users can use the vehicle's eSIM module to implement networking-related application functions in the smart cockpit (wherein the smart cockpit is a system for human-computer interaction on the car, including networking-related applications such as navigation, video, music, etc.).

[0095] In this implementation, the eSIM management platform of the target country operator can be used to connect the vehicle to the Internet with the lowest traffic cost during the vehicle sales phase, so that the vehicle can be sold to the user.

[0096] Furthermore, the eSIM module 40 described in this example is also used to output the traffic test result to the number management platform 20 after the traffic test is completed; the number management platform 20 is also used to obtain new number resources to be switched when there is a problem with the traffic test result; the number management platform 20 is also used to send the new number resources to be switched to the test period operator eSIM management platform corresponding to the target operator for multiple traffic tests.

[0097] In this implementation, after the eSIM management platform of the test operator performs air number writing on the eSIM module in the vehicle TBOX, the tester can open the vehicle machine and use the application to perform manual testing of traffic availability. If there is a problem with the test result, the tester can manually send a new code number resource to be switched on the code number management platform. Then the code number management platform sends the new code number resource to be switched to the eSIM management platform of the test operator for multiple traffic availability tests.

[0098] In the technical solution provided in this embodiment, the operators and their roaming cost information of the domestic research and development stage, overseas production and assembly stage, and overseas vehicle sales stage of the exported vehicles can be configured through the number management platform, and the operator with the lowest traffic cost can be obtained after comparing the costs. Then, the number can be written to the vehicle-mounted eSIM module over the air to achieve the lowest-cost export vehicle traffic usage.

[0099] For example, in order to help understand the implementation process of the eSIM card number information switching system obtained by combining this embodiment with the above-mentioned embodiment 1, the example of a car factory in country A planning to export vehicles to the target sales country B, the vehicle R&D base is in country A, and the vehicle production and assembly is in country C is used as an example, but the scheme is not limited. Traffic needs to be used in the R&D, production and assembly, and sales stages. In order to save traffic costs, the number resources of three different operators are used in countries A, B, and C for traffic use, as follows:

[0100] 1. During the vehicle development phase, the number management platform obtains the target sales country B and its operator O1 from the Internet of Vehicles platform, and then obtains the traffic availability operators (O1, O2, O3, etc.) and traffic cost information per M traffic cost (C2, C3, C4, etc.) in the country A where the development phase is located on the number management platform. If Ox is calculated as the lowest cost operator, the number management platform sends the number resources of Ox operator to the eSIM management platform of Ox operator to the eSIM module of the vehicle TBOX, and the eSIM module completes the number resource download. Then the R&D personnel open the navigation and other network applications in the smart cockpit to manually test the traffic availability.

[0101] 2. During the vehicle production and assembly stage, the number management platform obtains the target sales country B and its operator O1 from the Internet of Vehicles platform, and then obtains the operators (P1, P2, P3, etc.) with traffic availability in the production stage location C and their traffic cost information, and the cost per M of traffic (D2, D3, D4, etc.). If Px is calculated to be the lowest cost operator, the number management platform sends the number resources of the Px operator to the eSIM management platform of the Px operator to the eSIM module of the vehicle TBOX, and the eSIM module completes the download of the number resources. Then the factory staff opens the navigation and other Internet applications in the smart cockpit to manually test the traffic availability.

[0102] 3. During the vehicle sales phase, the number management platform obtains the target sales country B and its operator O1 from the Internet of Vehicles platform, and sends the number resources of the O1 operator to the eSIM management platform of the O1 operator to the eSIM module of the vehicle TBOX, and the eSIM module then completes the number resource download. After the vehicle is sold, it ensures that the owner can use navigation and other Internet applications normally in the smart cockpit.

[0103] Reference Figure 3 The present application provides an eSIM card code number information switching system and a method for switching eSIM card code number information. Figure 3 This is a flow chart of the first embodiment of the eSIM card code number information switching method of the present application, wherein the eSIM card code number information switching system includes: an Internet of Vehicles platform, a code number management platform, an operator eSIM management platform and an eSIM module.

[0104] In this embodiment, the eSIM card number information switching method includes steps S10 to S40:

[0105] Step S10: The number management platform determines the operator roaming data of the export target country of the export vehicle from the Internet of Vehicles platform according to the triggered number information switching request.

[0106] It should be noted that the eSIM card (Embedded-SIM) is a SIM card embedded in export vehicles. The vehicle can connect normally and use data traffic and other functions through the eSIM card.

[0107] It should be noted that the Internet of Vehicles platform is an information management platform for exported vehicles, which provides the vehicle identification number (VIN), vehicle tbox number, vehicle SIM card three-code information, SIM card target country name and operator name information, etc.

[0108] The number management platform is a platform for managing the eSIM card numbers. It supports the configuration of the operator information and traffic cost information of the eSIM card for export vehicles. When the eSIM card number information needs to be switched, the number resource information to be switched (such as the above three-code information, operator information, etc.) will be notified to the operator's eSIM management platform to switch the eSIM card number.

[0109] It should be noted that the code number information switching request is a request to switch the eSIM card code number when a traffic test is required when the vehicle is in the domestic research and development stage, overseas production and assembly stage, overseas vehicle sales stage, etc.

[0110] Among them, the export target country is the country to which the exported vehicles will be exported.

[0111] It should be noted that operator roaming data refers to the data usage generated when the eSIM card data roams to the network coverage area of ​​the export target country.

[0112] Among them, the operator roaming data may include operator information of the export target country, the cost per M of traffic of different operators roaming to the location of the eSIM card, etc., which is not limited in this embodiment.

[0113] In a feasible implementation, the operator roaming data includes an operator list and a roaming cost list; step S10 of this embodiment may include the steps: when the number management platform triggers the number information switching request of the export vehicle, it generates an information acquisition instruction, and sends the information acquisition instruction to the Internet of Vehicles platform; the Internet of Vehicles platform sends the operator information of the export target country of the export vehicle to the number management platform according to the information acquisition instruction; the number management platform obtains the operator information list and roaming cost list of the export target country according to the operator information.

[0114] It should be noted that the information acquisition instruction is an instruction generated by the number management platform to obtain the number resource information to be switched (such as the above three-code information, operator information, etc.) from the Internet of Vehicles platform.

[0115] It should be noted that the operator list is a list of operator information of telecommunication services stored in the Internet of Vehicles platform, wherein the operator list includes operator information of multiple countries, and each country includes information of multiple different operators. The information of multiple different operators in the export target country can be determined based on the operator list.

[0116] The roaming cost list is a detailed breakdown of the costs incurred when using roaming services under different circumstances, such as data traffic charges, call charges, and other specific cost information when roaming to the export target country from different regions during the domestic R&D stage, overseas production and assembly stage, and overseas vehicle sales stage.

[0117] Through the roaming cost list, the specific circumstances of various fees when export vehicles use roaming services at different stages can be clearly understood, so as to select the most appropriate eSIM card code number.

[0118] Specifically, when the code information switching request of the export vehicle is triggered, the code management platform obtains the operator information O1 of the export target country of the export vehicle from the Internet of Vehicles platform, and then obtains the operator information list of multiple countries that can be associated for testing (O2, O3, O4, etc.) and the roaming cost list per M of traffic roaming to the location of the eSIM card (C2, C3, C4, etc.) through the operator information O1.

[0119] In this implementation manner, by obtaining the operator list and roaming cost list, the specific circumstances of various fees for export vehicles using roaming services at different stages can be clarified so as to select the most appropriate operator.

[0120] Step S20: the number management platform determines the target operator according to the operator roaming data, and sends the number issuance notification and the number resources to be switched to the operator eSIM management platform corresponding to the target operator.

[0121] It should be noted that the target operator is the most suitable telecommunications operator (for example, the one with the lowest data traffic fee, the lowest call fee, etc.) selected based on the above operator list and roaming cost list.

[0122] The code number issuance notification is a notification of issuing the code number resources to be switched after the target operator is determined. The code number resources to be switched are the resources that the eSIM card of the export vehicle needs to switch information, such as the above three code information, operator information, etc.

[0123] It should be noted that the operator's eSIM management platform is a management platform used to send the information of code resources to be switched to exported vehicles when the vehicle is in various stages, such as the domestic research and development stage, overseas production and assembly stage, and overseas vehicle sales stage.

[0124] In a feasible implementation, step S20 of this embodiment may include the steps of: the number management platform determines the address of the location of the exported vehicle at different stages, the different stages including the vehicle research and development stage, the production and assembly stage, and the vehicle sales stage; the number management platform determines the minimum value of the roaming traffic cost between the address and the export target country based on the roaming cost list; the number management platform determines the target operator from the operator information list based on the minimum value.

[0125] It should be noted that the vehicle R&D stage is the period of design, technology development, engineering verification and other work for export vehicles. The production and assembly stage is the process of putting the completed design into practice, manufacturing and assembling various parts to form a complete vehicle. The vehicle sales stage is the process of bringing the produced vehicles to the market and selling them to end consumers through various sales channels and methods, such as dealer networks, online platforms, etc.

[0126] At each of the above stages, the connectivity of the eSIM cards of exported vehicles needs to be tested to ensure the quality of the produced vehicles.

[0127] Specifically, after obtaining the above-mentioned operator list and roaming cost list, according to the addresses at different stages, the number management platform can obtain the minimum cost Cx and its corresponding target operator Ox in the roaming cost list (C2, C3, C4, etc.), and set Ox as the target operator.

[0128] In this implementation, by determining the traffic usage costs of export vehicles in the domestic R&D stage, overseas production and assembly stage, and overseas vehicle sales stage, the cost of eSIM card connectivity at different stages can be reduced.

[0129] Step S30: The operator's eSIM management platform sends the code number resource to be switched to the eSIM module of the export vehicle according to the code number notification.

[0130] Step S40: the eSIM module downloads the code number resource to be switched to replace the original preset code number.

[0131] It should be noted that the eSIM module uses the eSIM card to remotely configure and manage user network connection information and other information. The eSIM module can be used to conveniently switch operators.

[0132] The original preset code number is the code number preset by default in the current period of the eSIM card of the eSIM module.

[0133] The eSIM module supports the operator's eSIM management platform to remotely send code resources to the eSIM module. The eSIM module can download the code resources of the eSIM card to the module to replace the default preset code and complete the over-the-air number writing.

[0134] In this implementation, through the eSIM module, the operator switching of the eSIM can be conveniently achieved based on the number resources remotely issued by the operator's eSIM management platform.

[0135] In the technical solution provided in this embodiment, since this embodiment configures the operator roaming data of the export vehicle through code number management to switch the code number resources to be switched on the operator's eSIM management platform and write them into the eSIM module, this can achieve the lowest-cost use of export vehicle traffic, and effectively reduce the traffic usage costs of export vehicles in the domestic research and development stage, overseas production and assembly stage, and overseas vehicle sales stage.

[0136] Based on this application Figure 3 The first embodiment of the present application proposes a second embodiment of the eSIM card code information switching method, which is the same or similar to the above-mentioned embodiment 1. Please refer to the above introduction and will not be repeated later.

[0137] The operator eSIM management platform described in this example includes a test period operator eSIM management platform; after the step of the number management platform determining the target operator according to the operator roaming data, it also includes: when the export vehicle is in the vehicle research and development stage or the production and assembly stage, the number management platform sends the number issuance notification and the number resources to be switched to the test period operator eSIM management platform corresponding to the target operator; the test period operator eSIM management platform sends the number resources to be switched to the eSIM module of the export vehicle for air number writing according to the number issuance notification; the eSIM module replaces the original preset number with the number resources to be switched for traffic testing.

[0138] It should be noted that the operator's eSIM management platform during the testing period is a management platform that sends the code resource information to be switched to the export vehicle for traffic testing during the vehicle testing period (i.e. the vehicle research and development stage, the production and assembly stage).

[0139] For ease of understanding, for example Figure 2 As shown, when the export vehicle is in the vehicle research and development stage or the production and assembly stage, the code number management platform (i.e., the export vehicle SIM card code number management cloud platform) obtains the target country and operator information of the export vehicle from the Internet of Vehicles platform (i.e., the export vehicle Internet of Vehicles cloud platform). Then the export vehicle SIM card code number management cloud platform sends the code number issuance notification to the test period operator eSIM management platform (for example, A2 country operator, B2 country operator, C2 country operator, etc.). The test period operator eSIM management platform writes the number of the eSIM module of the vehicle-mounted TBOX in the air according to the code number resources to be switched. The eSIM module replaces the original preset code number with the code number resources to be switched for traffic testing, and completes the manual test traffic.

[0140] In this implementation, traffic testing with the lowest traffic cost during the vehicle development and production assembly stages can be achieved through the trial operator's eSIM management platform.

[0141] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the eSIM card code information switching system and method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.

All equivalent structural changes made using the contents of the present application specification and drawings under the technical concept of the present application, or direct / indirect applications in other related technical fields are included in the patent protection scope of the present application.
