Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular to a method, system, and medium for automatically compiling an LPA for an eSIM device. Background Art

[0002] RSPeSIM is currently gaining increasing popularity in the IoT sector, but this also places higher demands on IoT devices, requiring them to have the ability to write numbers, meaning they must integrate the LPA functional module. However, IoT device manufacturers are generally small and medium-sized enterprises with limited R&D capabilities and unfamiliarity with GSMA specifications. This leads to long R&D cycles, which severely restricts the time it takes for devices to go online. To help devices go online as quickly as possible, LPA SDKs are generally provided to device manufacturers through offline integration and porting. However, the wide variety of IoT devices and the large differences in operating systems make offline integration inefficient. The LPA (Local Profile Assistant) on IoT eSIM devices is used to download profiles (including file systems, network authentication keys, applications, and other data). Before profile data is written to the physical eSIM card, it must be processed by the device LPA. However, there is currently no single LPA; operators, card vendors, device manufacturers, and others may all be LPA developers. This poses certain security risks to profile data transmission and eSIM platform access. Summary of the Invention

[0003] The embodiments of the present invention provide an automatic LPA compilation method, system, and medium for eSIM devices, aiming to solve the problems of low offline docking efficiency and lack of LPA legitimacy management and identity authentication.

[0019] See also Figure 1 , Figure 1This is a schematic diagram of an application scenario for the automatic LPA compilation method for eSIM devices provided by an embodiment of the present invention. This application scenario includes an LPA management platform 30, an eSIM platform 20, and an eSIM device 10. An eSIM device is typically an IoT terminal device. The eSIM platform is used to manage the eSIM device, and the LPA management platform is used to implement LPA identity authentication. An eSIM is an electronic SIM card, a data file that can be downloaded to a mobile terminal via the internet. With it, various terminals can connect to the internet, make calls, send text messages, and more. Functionally, it is identical to a regular SIM card; any device with mobile network access can use an eSIM. The plug-and-play, pre-integration, then number-writing feature of the eSIM card offers advantages and convenience for the mass production of IoT terminals. Directly embedding the eSIM blank card during device production meets the low-cost, high-security, and high-stability requirements of IoT terminals. LPA (Local Profile Assistant) is also known as the local profile assistant. Current eSIM device number writing has the following shortcomings: LPA function development cycles for IoT eSIM devices are long, making it difficult to quickly launch projects; there is a lack of unified and standardized management of eSIM devices and LPAs; and LPAs are non-unique, posing security risks. To this end, the LPA automatic compilation method for eSIM devices proposed in this embodiment realizes unified management of IoT eSIM devices and LPA through online automatic compilation of the IoT device LPA SDK. The device and platform implement identity authentication and authorization of LPA access to the eSIM platform through the newly added LPA identity authentication function module, ensuring the legality and security of the access.

[0020] The automatic LPA compilation method for eSIM devices in this embodiment is applied to the automatic LPA compilation method system for eSIM devices. Device manufacturers register on the platform, manage their devices, and automatically complete the LPA SDK compilation process. The generated SDK has built-in LPA authentication functionality. Before downloading a profile, the device first performs LPA identity authentication, and only after successful authentication can the profile download operation proceed. This system primarily includes: an LPA management platform, an IoT eSIM device, and an eSIM platform. Before describing the automatic LPA compilation method for eSIM devices in this embodiment, a brief introduction to the functions of the LPA management platform, IoT eSIM device, and eSIM platform in this embodiment is provided.

[0021] First, the functions of the LPA management platform in this embodiment are introduced. The LPA management platform includes manufacturer management, device management, automatic compilation, and LPA authentication functions. The specific functions are as follows:

[0022] 1) Manufacturer management: Equipment manufacturers upload their business licenses, sign agreements, and complete account application on the platform.

[0023] 2) Device management: Device manufacturers complete device registration management on the platform, including device model, software version, EID, IMEI, compilation tool and version, etc.

[0024] 3) Automatic Compilation: Select the appropriate compilation tool and version. The backend will automatically match the LPA source code. You can choose either "one device, one key" or "one model, one key" for security. The SDK will be generated based on the device model, EID, and IMEI. In addition to standard LPA functionality, the SDK also includes a generated LPA ID, authentication key, hash algorithm, and authentication request functionality. If the system does not have the appropriate compilation tool, you can upload it yourself and compile it.

[0025] 4) LPA authentication function: securely stores relevant information such as device model, EID, IMEI, authentication key, and LPAID, and completes the identity authentication of LPA when LPA accesses the eSIM platform.

[0026] Next, the functions of the eSIM device in this embodiment are introduced. The IoT eSIM device refers to an eSIM device that integrates the LPASDK function. The LPASDK can be integrated on the communication module, the IoT device MCU, or the main device. The LPASDK includes LPA authentication and standard LPA functions. The specific functions are as follows:

[0027] 1) LPA authentication: Read the device's EID and IMEI, and generate an authentication value through HASH calculation based on the EID, IMEI, authentication key and other information. The authentication process is the first step when accessing the eSIM platform.

[0028] 2) LPA: GSMA standard LPA functions, including initial authentication, profile download, etc.

[0029] Finally, the functions of the eSIM platform in this embodiment are introduced. The IoT eSIM platform includes standard DP+ function and LPA authentication function. LPA authentication mainly transmits the received LPA identity authentication request of the IoT eSIM device to the LPA management platform.

[0030] The following is a detailed description of the LPA automatic compilation method of the eSIM device. Figure 2 As shown, the method includes the following steps S110-S150.

[0031] S110. The LPA management platform processes the registration of the eSIM device to obtain registration information, and generates a corresponding LPA SDK using a compilation tool according to the registration information, wherein the SDK includes an LPA ID and an authentication value;

[0032] In this embodiment, the device manufacturer first registers an account in the LPA management platform. The device manufacturer then uses this account to register the manufacturer's eSIM devices, and all of the manufacturer's eSIM devices are registered in the LPA management platform. When registering an eSIM device, the manufacturer needs to upload the device model, software version, EID, IMEI, compilation tool and version, and other information. This information constitutes the registration information of the eSIM device. After the device manufacturer completes the registration, the LPA management platform will first automatically compile the LPASDK using the compilation tool. SDK (Software Development Kit) refers to the software development kit. The SDK generation process is as follows:

[0033] The LPA management platform matches the LPA source code in the background according to different eSIM devices to obtain the LPA source code corresponding to the eSIM device; the LPA source code is used by the compilation tool to generate the corresponding LPASDK according to the device model, EID and IMEI, wherein the registration letter includes the device model, the EID and the IMEI. Because different eSIM devices often have different operating systems and operating environments, it is necessary to pre-configure the corresponding LPA source code for various eSIM devices. Then, when compiling through the compilation tool, it is only necessary to match it with the LPA source code to obtain the LPA source code corresponding to the eSIM device and give it to the compilation tool, and then the compilation tool will automatically compile the complete SDK. During the compilation process of the compilation tool, it is necessary to generate according to the device model, EID and IMEI, among which the device model refers to the type number of the eSIM device; EID refers to the citizen network electronic identity, and eID is a network identity based on cryptographic technology and a smart security chip as a carrier. It can remotely identify the identity online without leaking identity information; IMEI refers to the International Mobile Equipment Identity (IMEI), which is commonly known as the mobile phone serial number or mobile phone "serial number". It is used to identify each independent mobile phone and other mobile communication devices in the mobile phone network, which is equivalent to the ID card of the mobile phone. In addition to the standard LPA function, the SDK also includes the generated LPAID, authentication key, HASH algorithm and authentication request function. Among them, the LPAID is automatically generated when registering in the LPA management platform. The generated ones can be diverse and are not limited here. In addition, the LPA management platform also generates an authentication value. The specific process is as follows:

[0034] The LPA management platform generates an authentication value through a HASH operation based on the EID, the IMEI, and the authentication key. Specifically, HASH is a method of transforming an input of arbitrary length (also called a pre-image) into an output of fixed length through a hash algorithm, and the output is the hash value. This conversion is a compression mapping, that is, the space of hash values is usually much smaller than the space of inputs, and different inputs may hash to the same output, so it is impossible to determine the unique input value from the hash value. Simply put, it is a function that compresses a message of arbitrary length into a message digest of a fixed length. In this embodiment, the EID, IMEI, and authentication key are used as HASH inputs for calculation to generate an authentication value.

[0035] It should be noted that the authentication key in this embodiment is allocated by the LPA management platform. The specific allocation principle is one key per device or one key per type, that is, the LPA management platform allocates the authentication key according to the number of eSIM devices; or, allocates the authentication key according to the device signal of the eSIM device.

[0036] S120: The eSIM device obtains its LPA ID and authentication value, and transparently transmits the LPA ID and authentication value to the LPA management platform through the eSIM platform to request LPA identity authentication;

[0037] In this embodiment, after the device manufacturer completes the registration of the eSIM device on the LPA management platform, it can obtain the LPAID and the assigned authentication key, and then the device manufacturer will solidify the LPAID and authentication key into the eSIM device. In this way, when the eSIM device wants to perform LED identity authentication, it can directly obtain the LPAID of the device itself. As for the authentication value, it is generated in the following way: the eSIM device obtains the EID, IMEI and authentication key of the device itself, and generates an authentication value through HASH operation based on the EID, IMEI and authentication key of the device itself. Specifically, first obtain the EID, IMEI and authentication key of the device itself (the authentication key is obtained by the device manufacturer from the LPA management platform and then solidified into the device), and then use the EID, IMEI and authentication key as the input of HASH to calculate and generate the authentication value.

[0038] S130. The LPA management platform performs LPA identity authentication based on the LPAID and authentication value from the eSIM device and the LPAID and authentication value in the SDK to generate an authentication result, and returns the authentication result to the eSIM platform.

[0039] In this embodiment, the LPA management platform receives an LPA authentication request from an eSIM device and performs LPA authentication. The LPA authentication process is as follows: the LPA management platform determines whether the LPAID and authentication value from the eSIM device are identical to those in the SDK; if so, a successful LPA authentication result is generated. Specifically, the LPA management platform compares the LPAID of the eSIM device with the LPAID in the SDK, and the authentication value of the SIM device with the authentication value in the SDK. If both are identical, the LPA authentication is considered successful, and a successful LPA authentication result is generated. This authentication result is then transmitted back to the eSIM platform.

[0040] S140. The eSIM platform notifies the card data management platform of the authentication result and allows downloading of the profile based on the authentication result.

[0041] In this embodiment, the card data management platform, DP+, is used to store and manage card numbers. The LPA management platform notifies DP+ of the authentication result, which DP+ then identifies and issues instructions to allow or deny profile downloads. Specifically, the eSIM platform's card data management platform determines whether to allow profile downloads based on the authentication result. If the LPA identity authentication result is successful, the eSIM device is allowed to download the profile; if the LPA identity authentication result is unsuccessful, the eSIM device is denied access.

[0042] S150: The eSIM device downloads the profile from the eSIM platform and writes the profile into the eSIM card.

[0043] In this embodiment, after completing LPA identity authentication, the LPA completes profile download by calling the communication chip / module interface and writes the applied profile into the eSIM card.

[0044] By implementing this embodiment, LPASDK compilation is automatically implemented online, which improves compilation efficiency while achieving unified management of IoT eSIM devices and LPA; a new LPA authentication mechanism is added to ensure the legal access of LPA through LPA identity authentication.

[0045] To further understand the LPA automatic compilation method of the eSIM device of this embodiment, please refer to Figure 3 The following example describes the interaction process between the LPA management platform, the eSIM platform, and the eSIM device in the LPA automatic compilation system of the eSIM device.

[0046] 1) The device manufacturer completes the account application and IoT eSIM device registration on the LPA management platform. According to the one-device-one-code or one-model-one-code, one-device-one-LPASDK or one-model-one-LPASDK generation rules, the LPASDK is compiled online. The generated LPASDK has the LPA authentication function.

[0047] 2) IoT eSIM devices integrate LPASDK functions and read EID and IMEI information by calling communication chips, modules or slave device interfaces.

[0048] 3) LPA accesses the eSIM platform, first making an LPA identity authentication request and uploading the LPA ID and authentication value.

[0049] 4) The LPA authentication module on the eSIM platform transparently transmits the authentication request to the LPA management platform. The LPA authentication module on the LPA management platform compares the LPAID and authentication value uploaded by the device with the platform's self-generated value, completes the LPA identity authentication, and returns the authentication result.

[0050] 5) The eSIM platform LPA authentication function notifies DP+ of the authentication result. If it passes, subsequent profile download requests are allowed; if it fails, they are rejected.

[0051] 6) The IoT eSIM device receives the authentication result. If it passes, it triggers the standard LPA application profile download. If it fails, it terminates access to the eSIM platform.

[0052] 7) Standard LPA applies to the eSIM platform for profile download, GSMA standard interface.

[0053] 8) Standard LPA completes profile download by calling the communication chip / module interface and writes the applied profile into the eSIM card.
