Description

Technical Field

[0001] This invention relates to a method for downloading data, and more particularly to a method, electronic device, and storage medium for downloading telecommunications operator configuration files. Background Technology

[0002] An embedded Subscriber Identity Module (eSIM) card is a programmable SIM card integrated into a device, replacing the traditional physical SIM card. eSIM cards can store and switch profiles of different telecom operators, allowing users to switch operators more easily.

[0003] It's important to note that eSIM cards can directly modify the telecom operator's profile via software. Users simply need to download and save the telecom operator profile to the eSIM card, and the eSIM card can then switch telecom operators and networks based on that profile. However, before the eSIM card is activated on the electronic device, the device has no network access, and it cannot download the telecom operator profile on its own. Summary of the Invention

[0004] In view of the above, it is necessary to provide a method, electronic device, and storage medium for downloading telecom operator configuration files to solve the problem that mobile phones cannot download telecom operator configuration files when the eSIM card is not activated.

[0005] This invention provides a method for downloading a telecommunications operator's configuration file, applied in an electronic device, comprising: when changing the settings of an Embedded Subscriber Identity Module (eSIM), the eSIM device transmits eSIM change information to a mobile phone via Bluetooth; the mobile phone transmits the eSIM change information to a Mobile Network Operator (MNO) server; the MNO server verifies the eSIM change information, generates a transaction identifier and server signature information, and transmits the transaction identifier and server signature information to the mobile phone; wherein, the mobile phone transmits the transaction identifier and server signature information to the eSIM device via Bluetooth; the eSIM device, after verifying the eSIM change information based on the transaction identifier and server signature information, generates an embedded universal integrated circuit card. The mobile network operator (CNO) sends the embedded universal integrated circuit card (eUICC) signature information to the mobile phone via Bluetooth. The mobile phone then sends the eUICC signature information to the mobile network operator's server. After verifying the eUICC signature information, the CNO server sends the carrier profile metadata to the mobile phone. The mobile phone then sends the eUICC metadata to the embedded subscriber identification module (eUICC) device via Bluetooth. The eUICC device performs Profile Policy Rules (PPR) checks on the eUICC metadata and generates a confirmation download message, which is then sent to the mobile phone via Bluetooth. The mobile phone then sends the confirmation download message to the CNO server. Upon receiving the confirmation download message, the CNO server sends the eUICC data packet to the mobile phone. The mobile phone then sends the eUICC data packet to the eUICC device via Bluetooth. Finally, the eUICC device writes the eUICC data packet to its eUICC card and sends the writing result to the mobile phone via Bluetooth. The mobile phone then sends the writing result to the CNO server.

[0006] This invention also provides an electronic device, including a memory, a processor, and a program for downloading a telecommunications operator's configuration file stored in the memory and executable on the processor. The electronic device further includes a data transmission module, a data verification module, and a data writing module. When the program for downloading the telecommunications operator's configuration file is executed by the processor, it performs the following steps: When the embedded subscriber identity module (eSIM) setting needs to be changed, the eSIM device transmits the eSIM change information to a mobile phone via Bluetooth. The mobile phone transmits the eSIM change information to a mobile network operator (MNO) server. After verifying the eSIM change information, the MNO server generates a transaction identifier and server signature information, and transmits the transaction identifier and server signature information to the mobile phone. The mobile phone transmits the transaction identifier and server signature information to the eSIM device via Bluetooth. After verifying the eSIM change information based on the transaction identifier and server signature information, the eSIM device generates an embedded universal integrated circuit card (eUICC) signature information and transmits it to the mobile phone via Bluetooth. The mobile phone transmits the embedded general-purpose integrated circuit card (GPIB) signature information to the mobile network operator (CNO) server. After verifying the GPIB signature information, the CNO server transmits carrier profile metadata to the mobile phone. The mobile phone then transmits the carrier profile metadata to an embedded user identification module (e.g., a sub-user identification module) via Bluetooth. The e.g., the ...

[0007] This invention also provides a storage medium storing a computer program, which, when executed, implements the steps of the aforementioned method for downloading a telecommunications operator's configuration file.

[0008] The method, electronic device, and storage medium for downloading telecom operator configuration files in this embodiment of the invention connect the device and mobile phone via Bluetooth without changing the download process defined in the original specifications. The download request and download data are transmitted via Bluetooth, and the configuration file is finally downloaded and the eSIM card is activated. Attached Figure Description

[0018] Figure 1 This is a schematic diagram of the system architecture for downloading telecommunications operator configuration files according to an embodiment of the present invention.

[0019] The system 100 for downloading telecom operator profiles in this embodiment of the invention includes a Mobile Network Operator (MNO) server 110, a mobile phone 120, an Embedded Subscriber Identity Module (eSIM) device 130, a Local Profile Assistant (LPA) software development kit (SDK) 140, an LPA Manager 150, and LPA User Interfaces 160 and 170. The various devices and components are connected via Bluetooth and HyperText Transfer Protocol Secure (HTTPS).

[0020] It should be noted that the system 100 for downloading telecom operator configuration files in this embodiment of the invention is a network architecture well known to those skilled in the art. The technical solution of the present invention is mainly based on this architecture and the SGP.22 download specification defined by GSMA, improving the original data transmission method. Therefore, the working principle of some components will not be described in detail.

[0021] When downloading an eSIM profile begins, the eSIM device 130 transmits a download network request to the mobile phone 120 via Bluetooth. Upon receiving the download network request, the mobile phone 120 accesses the MNO server 110 to exchange data and obtain the eSIM profile, simultaneously transmitting the profile to the eSIM device 130 via Bluetooth. Multiple network interaction requests are required during the download process, with Bluetooth acting as a bridge to ensure accurate transmission of network interaction data between the eSIM device 130 and the MNO server 110.

[0022] Figure 2 This is a flowchart illustrating the steps of a method for downloading a telecom operator's configuration file according to an embodiment of the present invention. The method is applied to electronic devices, including mobile wireless routers with eSIM cards, smartwatches, GPS positioning devices, and any calculator device capable of establishing a Bluetooth connection with a mobile phone and possessing an eSIM card. Depending on different requirements, the order of the steps in the flowchart can be changed, and some steps can be omitted.

[0023] Step S1: When the eSIM settings need to be changed, the eSIM device 130 transmits the eSIM change information to the mobile phone 120 via Bluetooth, and the mobile phone 120 transmits the eSIM change information to the MNO server 110.

[0024] In step S2, after verifying the eSIM replacement information, the MNO server 110 generates a "Transaction Identifier (TransactionID)" and "Server Signature Information," and transmits the "Transaction Identifier" and "Server Signature Information" to the mobile phone 120. The mobile phone 120 then transmits the "Transaction Identifier" and "Server Signature Information" to the eSIM device 130 via Bluetooth.

[0025] In step S3, after verifying the eSIM replacement information based on the "transaction identifier" and the "server signature information," the eSIM device 130 generates "embedded universal integrated circuit card (eUICC) signature information" and transmits the "eUICC signature information" to the mobile phone 120 via Bluetooth. The mobile phone 120 then transmits the "eUICC signature information" to the MNO server 110.

[0026] In step S4, after verifying that the "eUICC signature information" is correct, the MNO server 110 sends the "telecom operator profile metadata" to the mobile phone 120, and the mobile phone 120 sends the "telecom operator profile metadata" to the eSIM device 130 via Bluetooth.

[0027] In step S5, the eSIM device 130 verifies the "telecom operator profile metadata" using "Profile Policy Rules (PPR)" and generates "confirmation download information," which is then transmitted to the mobile phone 120 via Bluetooth. The mobile phone 120 then transmits the "confirmation download information" to the MNO server 110.

[0028] In step S6, after receiving the "confirmation of download information", the MNO server 110 sends the "telecom operator configuration file data packet" to the mobile phone 120. The mobile phone 120 then sends the "telecom operator configuration file data packet" to the eSIM device 130 via Bluetooth.

[0029] In step S7, the eSIM device 130 writes the "telecom operator profile data packet" to its eSIM card (not shown) and transmits the "writing result information" to the mobile phone 120 via Bluetooth. The mobile phone 120 then transmits the "writing result information" to the MNO server 110.

[0030] In step S8, after receiving the "write result information", the MNO server 110 replies with "write confirmation information" to the mobile phone 120, and the mobile phone 120 transmits the "write confirmation information" to the eSIM device 130 via Bluetooth.

[0031] In step S9, after receiving the "write confirmation information", the eSIM device 130 deletes the "write result information" and completes the download process.
