[0033] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0034] For information transmission and command interaction between eUICC and terminals in IoT devices, the M2M solution defined in SGP.021 of the GSMA specification is complex to implement, has low practicality, is difficult to promote in the market, and has high deployment costs. Furthermore, EIS registration locks the profile to SM-SR, preventing users from flexibly managing the profile lifecycle, and pre-configuring the provisioning profile requires SMS capabilities. The consumer solution defined in SGP 22 V3.1 of the GSMA specification requires integration with an embedded SIM card (Embedded Subscriber Identity Module, eSIM), which is overly complex to implement and cannot easily achieve profile lifecycle management, resulting in low practicality and difficulty in market promotion. The IoT solution defined in SGP 32 of the GSMA specification is complex to deploy, the specification is still being updated and released, and the market is immature, making it difficult to promote.

[0035] This invention provides a profile download system for IoT devices, such as... Figure 1 As shown, the system includes OTA1 (Over-the-Air Technology), LPA2 (Local Profile Assistant) in the IoT device, and a number management platform 3. OTA1 responds to a profile download request sent by the user through the number management platform 3, generates a profile download SMS message based on the profile download request and profile download activation code, and sends the SMS message to LPA2 in the IoT device. LPA2 in the IoT device receives the profile download SMS message from OTA1, triggers the profile download, obtains the eUICC information in the IoT device, and retrieves the profile configuration file corresponding to the profile download activation code from the SMDP+ server. LPA2 converts the profile configuration file into a first APDU instruction and sends it to the eUICC corresponding to the eUICC information in the IoT device, enabling the eUICC to complete the profile download based on the first APDU instruction.

[0036] OTA1 connects to the SMS center of the profile operator, enabling it to send SMS messages. OTA1 also communicates with the number management platform 3 to obtain requests sent by users through the number management platform 3.

[0037] The OTA1 of the embodiment of the present application establishes a communication connection with the number management platform 3, can acquire the profile corresponding request sent by the user through the number management platform 3, and the OTA1 is connected to the SMS center of the profile operator, can convert the profile corresponding request sent by the number management platform 3 into the form of SMS, has the SMS sending capability, and sends the generated SMS to the LPA2 in the Internet of Things device.

[0038] The Internet of Things device of the embodiment of the present application is preset with a seed number (ProvisioningProfile) when the device is produced by a device manufacturer, provides network and OTA1 capability, and outputs a corresponding registration file EIS (including but not limited to EID (eUICC-ID, eUICC identification code), MSISDN (Mobile Station International Subscriber Directory Number, mobile user international number), a unique identification code (Integrated Circuit Card ID, ICCID) corresponding to each profile, and IMSI (International Mobile Subscriber Identity, international mobile user identification code), and the EIS registration file is imported to the profile number management platform 3, so that the number management platform 3 stores various identification codes, such as all profile download activation codes and identification codes corresponding to the downloaded profiles, which are only examples.

[0039] As shown in Figure 2a The user of the embodiment of the present application is registered to the corresponding number management platform 3 through the seed number information, so that the user selects the target profile required according to the business requirement to perform the download operation, the number management platform 3 determines the profile download activation code corresponding to the target profile selected by the user, and can assemble the determined profile download activation code and the profile into a profile download request and send it to the OTA1, the OTA1 checks the input information in the profile download request, generates a profile download SMS based on the profile download and the profile download activation code, and pushes the profile download SMS to the LPA2 in the Internet of Things device.

[0040] In this embodiment of the invention, LPA2 receives a profile download SMS pushed by OTA1, triggering profile download. LPA2 can obtain eUICC-related information from the IoT device through APDU commands (Application Protocol Data Unit, which is an application-level communication command format definition in the SIM card). LPA2 can also interact with the SMDP+ server (Subscription Manager Data Preparation Plus, whose main functions include profile preparation, secure encryption, storage, and allocation). Figure 2b As shown, LPA2 can sequentially call the InitiateAuthentication, AuthenticateClient, and GetBoundProfilePackage interfaces to obtain the profile configuration file corresponding to the profile download activation code in the profile download SMS. After obtaining the profile configuration file, LPA2 can convert the profile configuration file into the first APDU instruction and call the interface to send it to the eUICC in the IoT device, so that the eUICC can receive the APDU, load and install it, and complete the profile number download. Detailed interface descriptions will not be repeated here.

[0041] The IoT device profile download system provided by this invention responds to a profile download request sent by a user through a number management platform. Based on the profile download and activation code, it generates a profile download SMS message and sends it to the LPA in the IoT device. The LPA receives the profile download SMS message from the OTA and triggers the profile download, obtaining the eUICC information in the IoT device and the profile configuration file corresponding to the profile download activation code from the SMDP+ server. The LPA converts the profile configuration file into a first APDU instruction and sends it to the eUICC in the IoT device, enabling the eUICC to complete the profile download based on the first APDU instruction. This allows users to flexibly switch profiles according to business needs, solving the problem of profiles being locked to SM-SR after EIS registration. The system is more lightweight and easier to implement and promote in the market.

[0042] In an alternative embodiment, the LPA2 receives the profile download completion result feedback from the eUICC in the receiving IoT device, and sends the profile download completion result to the SMDP+ server and the number management platform 3, so that the SMDP+ server synchronously updates the profile state, and the number management platform 3 synchronously updates the profile state, wherein the number management platform 3 stores the identification code of the downloaded profile.

[0043] As shown in Figure 2a After the eUICC of the IoT device in the embodiment of the application completes the download (installation) of the profile, the profile download completion result can be fed back to the LPA2, and the LPA2 can notify the profile download completion result to the SMDP+ server and the number management platform 3, the SMDP+ server can synchronize the profile state based on the profile download completion result, and the number management platform 3 can also synchronously update the profile state.

[0044] After the eUICC of the application completes the download of the profile, the profile download result can be fed back to the LPA2, so that the LPA2 notifies the profile download result to the SMDP+ server and the number management platform 3, so as to update and synchronize the profile state in time, and ensure the timely update of the profile state.

[0045] Specifically, the profile download message is in the form of a string, and the profile download message at least includes the profile download corresponding character and the profile download activation code.

[0046] The message sent by the OTA1 of the embodiment of the application to the LPA2 can be in the form of a string, and can include but is not limited to the profile download corresponding character and the profile download activation code.

[0047] The message generated based on the profile download corresponding character and the profile download activation code is sent to the LPA, the content form of the message is more convenient and simple, and the subsequent LPA can analyze the profile download message and trigger the download of the profile.

[0048] In an optional embodiment, the OTA1 generates a profile management short message based on the profile management in the profile management request and the identification code of the profile in response to the user sending a profile management request through the number management platform 3, sends the profile management short message to the LPA2 in the Internet of Things device, the LPA2 receives the profile management short message, triggers the profile management, converts the identification corresponding to the profile management in the profile management short message and the identification code of the profile into a second APDU instruction, and sends the second APDU instruction to the eUICC in the Internet of Things device, so that the eUICC manages the corresponding profile based on the second APDU instruction.

[0049] The number management platform 3 stores the identification code of the profile that has completed downloading, and the identification code of the profile that has completed downloading is fed back by the eUICC in the Internet of Things device receiving the profile download completion result, and the profile download completion result is sent to the number management platform 3, so that the number management platform 3 synchronously updates and stores the profile state.

[0050] The number management platform 3 of the embodiment of the application stores the profile state that has completed downloading, and can be displayed to the user through a user interface. The user selects to manage the target profile based on the business demand according to all the profile states currently displayed, and the management of the target profile can include but is not limited to profile activation, profile invalidation and profile deletion.

[0051] As Figure 3As shown, when a user selects to activate a target profile, the number management platform 3 determines the target profile's identifier and generates a profile activation request based on the determined identifier and profile activation information. This request is then sent to OTA1. OTA1 checks the input information in the profile activation request sent by the number management platform 3, generates a profile activation SMS message based on the profile activation information and the profile's identifier, and pushes it to LPA2 in the IoT device. Specifically, the profile activation SMS message is in string format and includes at least the characters corresponding to profile activation and the profile's identifier. LPA2 receives the profile activation SMS message, triggers profile activation, and can send a successful push response back to OTA1 so that OTA1 can confirm that the profile activation SMS message was successfully pushed. Subsequently, OTA1 can send a successful request message back to the number management platform 3. LPA2 obtains the eUICC information in the IoT device and converts the identifier corresponding to profile activation and the profile's identifier in the profile activation SMS message into a second APDU instruction, which is then sent to the eUICC in the IoT device. The eUICC finds the corresponding profile based on the profile's identifier in the second APDU instruction and activates the corresponding profile based on the profile activation information.

[0052] In one optional implementation, LPA2 receives the profile activation completion result from the eUICC in the IoT device, and sends the profile activation completion result to the SMDP+ server and the number management platform 3, so that the SMDP+ server and the number management platform 3 can update the profile status synchronously.

[0053] like Figure 3 As shown, after the eUICC in the IoT device of this embodiment completes the profile activation, it can feed back the profile activation completion result to LPA2. LPA2 notifies the SMDP+ server and the number management platform 3 of the profile activation completion result. The SMDP+ server can synchronously update the corresponding profile status based on the profile activation completion result, and the number management platform 3 can also synchronously update the corresponding profile status based on the profile activation completion result.

[0054] like Figure 4As shown, when a user selects to invalidate a target profile, the number management platform 3 determines the target profile's identifier and generates a profile invalidation request based on the determined target profile identifier and profile invalidation, and sends it to OTA1. OTA1 checks the input information in the profile invalidation request sent by the number management platform 3, generates a profile invalidation SMS based on the profile invalidation and profile identifier, and pushes it to LPA2 in the IoT device. Specifically, the profile invalidation SMS is in string form and includes at least the characters corresponding to the profile invalidation and the profile identifier. LPA2 receives the profile invalidation SMS, triggers the profile invalidation, and can send a successful push response back to OTA1 so that OTA1 confirms that the profile invalidation SMS was successfully pushed. Then, OTA1 can send a successful request message back to the number management platform 3. LPA2 obtains the eUICC information in the IoT device and converts the identifier corresponding to the profile invalidation and the profile identifier in the profile invalidation SMS into a second APDU instruction, and sends it to the eUICC in the IoT device. The eUICC finds the corresponding profile based on the profile identifier in the second APDU instruction and performs invalidation processing on the corresponding profile based on the profile invalidation.

[0055] In one optional implementation, LPA2 receives the profile failure completion result fed back by eUICC in the IoT device, and sends the profile failure completion result to the SMDP+ server and the number management platform 3, so that the SMDP+ server and the number management platform 3 can update the profile status synchronously.

[0056] like Figure 4 As shown, after the eUICC in the IoT device of this embodiment of the invention completes the profile failure, it can feed back the profile failure completion result to LPA2. LPA2 notifies the SMDP+ server and the number management platform 3 of the profile failure completion result. The SMDP+ server can synchronously update the corresponding profile status based on the profile failure completion result, and the number management platform 3 can also synchronously update the corresponding profile status based on the profile failure completion result.

[0057] like Figure 5As shown, when a user selects to delete a target profile, the number management platform 3 determines the target profile's identifier and generates a profile deletion request based on the determined identifier and profile deletion information. This request is then sent to OTA1. OTA1 checks the input information in the profile deletion request sent by the number management platform 3, generates a profile deletion SMS message based on the profile deletion information and the profile's identifier, and pushes it to LPA2 in the IoT device. Specifically, the profile deletion SMS message is in string format and includes at least the characters corresponding to the profile deletion and the profile's identifier. LPA2 receives the profile deletion SMS message, triggers the profile deletion, and can send a successful push response back to OTA1 so that OTA1 can confirm that the profile deletion SMS message was successfully pushed. Subsequently, OTA1 can send a successful request message back to the number management platform 3. LPA2 obtains the eUICC information in the IoT device and converts the identifier corresponding to the profile deletion and the profile's identifier in the profile deletion SMS message into a second APDU instruction, which is then sent to the eUICC in the IoT device. The eUICC finds the corresponding profile based on the profile's identifier in the second APDU instruction and performs the deletion process on the corresponding profile based on the profile deletion information.

[0058] In one optional implementation, LPA2 receives the profile deletion completion result from the eUICC in the IoT device, and sends the profile deletion completion result to the SMDP+ server and the number management platform 3, so that the SMDP+ server and the number management platform 3 can update the profile status synchronously.

[0059] like Figure 5 As shown, after the eUICC in the IoT device of this embodiment completes the deletion of the profile, it can send the profile deletion completion result back to LPA2. LPA2 notifies the SMDP+ server and the number management platform 3 of the profile deletion completion result. The SMDP+ server can synchronously update the corresponding profile status based on the profile deletion completion result. The number management platform 3 can also delete the stored corresponding profile based on the profile deletion completion result. This is just an example.

[0060] The user of the present application can select a management request for a profile number through a number management platform, the OTA converts the profile-based management request into a profile management short message, the LPA receives the profile management short message, triggers the management of the corresponding profile, and realizes that the user can flexibly and conveniently realize profile life cycle management through the OTA1 scheme, and can update the profile state recorded in the SMDP+ server and the number management platform in time after completing the management of the profile.

[0061] Specifically, the LPA2 is integrated with a short message broadcast receiver, which creates a short message monitoring service, adds a short message receiving permission, and registers the short message broadcast receiver, and is used to receive the profile download short message or the profile management short message sent by the OTA1, and analyze the profile download short message or the profile management short message, and trigger the corresponding profile operation.

[0062] As shown in Figure 6 , in the prior art, the LPA triggers the download profile by scanning or inputting the activation code of the user equipment, and cannot remotely trigger the profile download, and as shown in Figure 7 , the LPA2 designed in the embodiment of the present application is integrated with a short message broadcast receiver, which can execute the corresponding profile operation through the profile download short message or the profile management short message pushed by the OTA1, and remotely triggers the profile operation, wherein the functions of the proxy module include but are not limited to receiving a short message, short message analysis, triggering profile download, profile activation, profile invalidation, and profile deletion.

[0063] In specific embodiments, as shown in Figure 8 , the LPA2 designed in the embodiment of the present application is integrated with a short message broadcast receiver, which can create a short message monitoring service, add a short message receiving permission, create and register a short message broadcast receiver, and is used to receive the short message pushed by the OTA1, and analyze the short message after receiving the short message, and trigger the corresponding profile operation, wherein the profile operation can include profile download, profile activation, profile invalidation, and profile deletion, which are only examples.

[0064] The LPA of the present application is integrated with a short message broadcast receiver, which is used to receive the short message sent by the OTA, and analyze the short message to perform the corresponding profile operation, realizes automatic and remote receiving of the short message sent by the OTA, does not need manual intervention of the user, and the remote management mode expands the management range and flexibility of the LPA.

[0065] The embodiment of the present application also provides a profile downloading method in an Internet of Things device, which is applied to an OTA1, an LPA2 and a number management platform 3 as shown in the figure. Figure 1 The OTA1 is connected with a short message center of a profile operator, so that the OTA1 has a short message sending capability, and the OTA1 is used for executing steps S101-S102, the LPA2 is used for executing steps S201-S202, and the number management platform 3 is used for executing step S301. Figure 9 The OTA1 is connected with a short message center of a profile operator, so that the OTA1 has a short message sending capability, and the OTA1 is used for executing steps S101-S102, the LPA2 is used for executing steps S201-S202, and the number management platform 3 is used for executing step S301.

[0066] In step S301, a profile downloading request is sent to the OTA.

[0067] In step S101, a profile downloading short message is generated based on the profile downloading and the profile downloading activation code in the profile downloading request.

[0068] In step S102, the profile downloading short message is sent to the LPA in the Internet of Things device.

[0069] In step S201, the profile downloading short message sent by the OTA is received, profile downloading is triggered, eUICC information in the Internet of Things device is acquired, and a profile configuration file corresponding to the profile downloading activation code in the profile downloading short message is acquired from an SMDP+ server.
