Description

[0002] The latest eSIM standard SGP.31 / 32 released by GSMA is specified for IoT devices to support eSIM technology. This standard defines the operation management of the eSIM profile of the eIM entity for managing IoT devices, including switching and deletion. In the above context, when the IoT device needs to operate the code number locally, the code number operation is usually completed through a remote request, that is, a request is sent to the device management platform related to the device, and the device management platform then sends a request to the eIM entity associated with the eSIM, and the eIM entity sends the eSIM operation instruction to the IoT device to implement the code number operation of the eSIM card. The implementation process of this method is lengthy, and it needs to go through the device management platform to the eIM and then to the device. There are too many intermediate links and the execution time is also long. At the same time, the IoT device may periodically connect to the eIM entity to query instructions, and the eIM instructions need to wait for a long time before they can be read and executed by the IoT device. In addition, when the network fails or the code number fails and the network cannot be connected, the method implemented by the device management platform cannot be connected to the network, and the eSIM card operation cannot be requested. Therefore, the situation where the eSIM card code number operation needs to be performed locally cannot be realized. Summary of the invention

[0014] When the remote eIM platform receives the instruction sending request, the remote eIM platform uses the second type of key to encrypt or sign the operation instruction sent by the remote eIM platform, and sends the encrypted or signed operation instruction to the Internet of Things configuration unit;

[0015] When the eSIM card receives the encrypted or signed operation instruction sent by the Internet of Things configuration unit, the encrypted or signed operation instruction is decrypted or verified using the second type of key, and the eSIM card executes the decrypted or verified operation instruction to perform code number operation.

[0016] In some embodiments, before sending the code number operation instruction to the Internet of Things configuration unit, the code number operation method further includes:

The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0040] Please refer to Figure 1 In an embodiment of the present invention, a code number operation method based on an eSIM card is provided, which is applied in an Internet of Things device. The Internet of Things device includes a device control unit, an eIM simulation unit, an Internet of Things configuration unit and an eSIM card, wherein at least one code number is set in the eSIM card. The code number operation method includes steps S10 to S30, which are described in detail below.

[0041] Step S10: When the device control unit receives the device trigger request, the device control unit sends the device trigger request to the eIM simulation unit.

[0042] In some embodiments, the device control unit may be device software built into an Internet of Things (IoT) device. When the IoT device triggers an operation, the device control unit receives a device trigger request and sends the device trigger request to the eIM simulation unit.

[0043] Step S20: the eIM simulation unit generates a code number operation instruction that complies with preset technical specifications in the remote eIM platform according to the device trigger request, and sends the code number operation instruction to the Internet of Things configuration unit.

[0044] In some embodiments, the preset technical specifications in the remote eIM platform include GSMA SGP.31 / 32. This technical specification requires that the eSIM card supporting GSMA SGP.31 / 32 must belong to one or more remote eIM platforms and have the key of the remote eIM platform built in. The instructions sent by the remote eIM platform to the eSIM card must be encrypted or signed and sent to the eSIM card for decryption or signature verification, and then the decrypted or verified instructions are executed. The IoT Profile Assistant (IPA) is located on the IoT device and acts as an agent between the eSIM card and the eSIM IoT Remote Manager (eIM). The IoT Profile Assistant connects to the remote eIM platform to receive instructions issued from the remote eIM platform and forwards them to the eSIM card. The IoT Profile Assistant itself cannot recognize the content of the instructions and only implements the forwarding function.

[0045] In some embodiments, a preset first type key is set in the eIM simulation unit and the eSIM card, for example, the preset first type key is key B, that is, the same key B is set in the eIM simulation unit and the eSIM card. After the eIM simulation unit generates a code number operation instruction that complies with the preset technical specifications in the remote eIM platform according to the device trigger request, the code number operation instruction is encrypted or signed using the key B in the eIM simulation unit to obtain the encrypted or signed code number operation instruction, and the encrypted or signed code number operation instruction is sent to the Internet of Things configuration unit.

[0046] In some embodiments, a preset second type key is set in the remote eIM platform and the eSIM card, for example, the preset second type key is key A, that is, the same key A is set in the remote eIM platform and the eSIM card. When the remote eIM platform receives the instruction sending request, the key A in the remote eIM platform is used to encrypt or sign the operation instruction sent by the remote eIM platform, and the encrypted or signed operation instruction is sent to the Internet of Things configuration unit.

[0047] Please refer to Figure 2In some embodiments, a preset first type key and a preset second type key are simultaneously set in the eSIM card, a preset first type key is set in the eIM simulation unit, and a preset second type key is set in the remote eIM platform. Assuming that the preset first type key is key B and the preset second type key is key A, therefore, key A and key B are set in the eSIM card, key A is set in the remote eIM platform, and key B is set in the eIM simulation unit. When the remote eIM platform receives the instruction sending request, the operation instruction issued by the remote eIM platform is encrypted or signed using key A in the remote eIM platform, and the encrypted or signed operation instruction is sent to the Internet of Things configuration unit. When the eIM simulation unit generates a code number operation instruction that meets the preset technical specifications in the remote eIM platform according to the device trigger request, the code number operation instruction is encrypted or signed using key B in the eIM simulation unit to obtain the encrypted or signed code number operation instruction, and the encrypted or signed code number operation instruction is sent to the Internet of Things configuration unit.

[0048] In some embodiments, the sending of the code number operation instruction is realized by judging whether the instruction type of the code number operation instruction meets the preset first type requirement. When the instruction type of the code number operation instruction meets the preset first type requirement, the code number operation instruction is sent to the Internet of Things configuration unit. When the instruction type of the code number operation instruction does not meet the preset first type requirement, the code number operation instruction is encrypted or signed using the first type key in the eIM simulation unit to obtain the encrypted or signed code number operation instruction, and the encrypted or signed code number operation instruction is sent to the Internet of Things configuration unit.

[0049] In some embodiments, by determining whether the instruction content in the code number operation instruction is any instruction content in a preset content library, if the instruction content in the code number operation instruction is any instruction content in the preset content library, then the instruction type of the code number operation instruction is determined to meet the preset first type requirement; if the instruction content in the code number operation instruction is not any instruction content in the preset content library, then the instruction type of the code number operation instruction is determined to not meet the first type requirement.

[0050] In some embodiments, the content library includes instruction content for querying the ID of the eSIM card and instruction content for adding a code number to the eSIM card. The instruction content of the code number operation instruction that does not meet the first type of requirements includes deleting the code number in the eSIM card, switching the code number in the eSIM card, and updating the keys of the eIM simulation unit and the eSIM.

[0051] Step S30: When the Internet of Things configuration unit receives the code number operation instruction, the Internet of Things configuration unit sends the code number operation instruction to the eSIM card, and the eSIM card executes the code number operation instruction to perform the code number operation.

[0052] In some embodiments, when the received code number operation instruction is an instruction obtained by encrypting or signing the code number operation instruction using the key B in the eIM simulation unit, the eSIM card will use the key B in the eSIM card to decrypt or verify the encrypted or signed code number operation instruction before executing the code number operation instruction, and the eSIM card executes the decrypted or verified code number operation instruction to perform the code number operation. When the received code number operation instruction is an instruction that meets the preset first type requirements, the eSIM card executes the code number operation instruction to perform the code number operation. When the received code number operation instruction is an instruction obtained by encrypting or signing the operation instruction issued by the remote eIM platform using the key A in the remote eIM platform, the eSIM card will use the key A in the eSIM card to decrypt or verify the encrypted or signed code number operation instruction before executing the code number operation instruction, and the eSIM card executes the decrypted or verified code number operation instruction to perform the code number operation.

[0053] In some embodiments, the present application reasonably utilizes the technical interface between the eSIM card and the remote eIM platform under the technical framework of the GSMA SGP.31 / 32 specification, and implements the code number operation of the local eSIM card without the need to make technical changes to the eSIM card and the remote eIM platform. The local can issue instructions to the eSIM card to perform code number operations such as switching and deletion. For example, when multiple code numbers are stored in the eSIM card, if one of the code numbers fails or the network is interrupted, the local can still switch to other code numbers to continue to connect to the network and work.

[0054] Please refer to Figure 3 In some embodiments, the embodiments of the present application provide an Internet of Things device, which includes a device control unit 10, an eIM simulation unit 20, an Internet of Things configuration unit 30 and a code number operation unit 40, and is configured with an eSIM card, which is described in detail below.

[0055] In some embodiments, the device control unit 10 is used to send the device trigger request to the eIM simulation unit 20 when receiving the device trigger request. The device control unit 10 may be the device software included in the IoT device. When the IoT device triggers an operation, the device control unit 10 receives the device trigger request and sends the device trigger request to the eIM simulation unit 20.

[0056] In some embodiments, the eIM simulation unit 20 is used to generate a code number operation instruction that complies with preset technical specifications in the remote eIM platform according to the device trigger request, and send the code number operation instruction to the Internet of Things configuration unit 30.

[0057] In some embodiments, the preset technical specifications in the remote eIM platform include GSMA SGP.31 / 32. This technical specification requires that the eSIM card supporting GSMA SGP.31 / 32 must belong to one or more remote eIM platforms and have the key of the remote eIM platform built in. The instructions sent by the remote eIM platform to the eSIM card must be encrypted or signed and sent to the eSIM card for decryption or signature verification, and then the decrypted or verified instructions are executed. The Internet of Things configuration unit 30 is located on the Internet of Things device and acts as a proxy between the eSIM card and the eSIM IoT remote manager. The Internet of Things configuration unit 30 connects to the remote eIM platform to receive instructions issued from the remote eIM platform and forwards them to the eSIM card. The Internet of Things configuration unit 30 itself cannot recognize the content of the instructions and only implements the forwarding function.

[0058] In some embodiments, a preset first type key is set in the eIM simulation unit 20 and the eSIM card. For example, the preset first type key is key B, that is, the same key B is set in the eIM simulation unit 20 and the eSIM card. After the eIM simulation unit 20 generates a code number operation instruction that complies with the preset technical specifications in the remote eIM platform according to the device trigger request, the code number operation instruction is encrypted or signed using the key B in the eIM simulation unit 20 to obtain the encrypted or signed code number operation instruction, and the encrypted or signed code number operation instruction is sent to the Internet of Things configuration unit 30.

[0059] In some embodiments, a preset second type key is set in the remote eIM platform and the eSIM card, for example, the preset second type key is key A, that is, the same key A is set in the remote eIM platform and the eSIM card. When the remote eIM platform receives the instruction sending request, the key A in the remote eIM platform is used to encrypt or sign the operation instruction sent by the remote eIM platform, and the encrypted or signed operation instruction is sent to the Internet of Things configuration unit 30.

[0060] Please refer back to Figure 2In some embodiments, a preset first type key and a preset second type key are set in the eSIM card at the same time, a preset first type key is set in the eIM simulation unit 20, and a preset second type key is set in the remote eIM platform. Assuming that the preset first type key is key B and the preset second type key is key A, therefore, key A and key B are set in the eSIM card, key A is set in the remote eIM platform, and key B is set in the eIM simulation unit 20. When the remote eIM platform receives the instruction sending request, the operation instruction issued by the remote eIM platform is encrypted or signed using key A in the remote eIM platform, and the encrypted or signed operation instruction is sent to the Internet of Things configuration unit 30. When the eIM simulation unit 20 generates a code number operation instruction that meets the preset technical specifications in the remote eIM platform according to the device trigger request, the code number operation instruction is encrypted or signed using key B in the eIM simulation unit 20 to obtain the encrypted or signed code number operation instruction, and the encrypted or signed code number operation instruction is sent to the Internet of Things configuration unit 30.

[0061] In some embodiments, the sending of the code number operation instruction is realized by judging whether the instruction type of the code number operation instruction meets the preset first type requirement. When the instruction type of the code number operation instruction meets the preset first type requirement, the code number operation instruction is sent to the Internet of Things configuration unit 30. When the instruction type of the code number operation instruction does not meet the preset first type requirement, the code number operation instruction is encrypted or signed using the first type key in the eIM simulation unit 20 to obtain the encrypted or signed code number operation instruction, and the encrypted or signed code number operation instruction is sent to the Internet of Things configuration unit 30.

[0062] In some embodiments, by determining whether the instruction content in the code number operation instruction is any instruction content in a preset content library, if the instruction content in the code number operation instruction is any instruction content in the preset content library, then the instruction type of the code number operation instruction is determined to meet the preset first type requirement; if the instruction content in the code number operation instruction is not any instruction content in the preset content library, then the instruction type of the code number operation instruction is determined to not meet the first type requirement.

[0063] In some embodiments, the content library includes instruction content for querying the ID of the eSIM card and instruction content for adding a code number to the eSIM card. The instruction content of the code number operation instruction that does not meet the first type of requirements includes deleting the code number in the eSIM card, switching the code number in the eSIM card, and updating the keys of the eIM simulation unit and the eSIM.

[0064] In some embodiments, the Internet of Things configuration unit 30 is used to send the code number operation instruction to the eSIM card when receiving the code number operation instruction.

[0065] In some embodiments, when the received code number operation instruction is an instruction obtained by encrypting or signing the code number operation instruction using the key B in the eIM simulation unit 20, the eSIM card will use the key B in the eSIM card to decrypt or verify the encrypted or signed code number operation instruction before executing the code number operation instruction, and the eSIM card executes the decrypted or verified code number operation instruction to perform the code number operation. When the received code number operation instruction is an instruction that meets the preset first type requirements, the eSIM card executes the code number operation instruction to perform the code number operation. When the received code number operation instruction is an instruction obtained by encrypting or signing the operation instruction issued by the remote eIM platform using the key A in the remote eIM platform, the eSIM card will use the key A in the eSIM card to decrypt or verify the encrypted or signed code number operation instruction before executing the code number operation instruction, and the eSIM card executes the decrypted or verified code number operation instruction to perform the code number operation.

[0066] In some embodiments, the code number operation unit 40 is used to enable the eSIM card to execute the code number operation instruction to perform the code number operation.

[0067] In some embodiments, the present application reasonably utilizes the technical interface between the eSIM card and the remote eIM platform under the technical framework of the GSMA SGP.31 / 32 specification, and implements the code number operation of the local eSIM card without the need to make technical changes to the eSIM card and the remote eIM platform. The local can issue instructions to the eSIM card to perform code number operations such as switching and deletion. For example, when multiple code numbers are stored in the eSIM card, if one of the code numbers fails or the network is interrupted, the local can still switch to other code numbers to continue to connect to the network and work.

[0068] In some embodiments, the embodiments of the present application provide a code number operation device based on an eSIM card, including: a memory for storing programs; and a processor for implementing a code number operation method by executing the programs stored in the memory.
