Description

Technical Field

[0001] This application relates to the field of wireless communication technology, particularly to the integration of low-altitude satellite communication and eSIM and Internet of Things (IoT) technologies. Specifically, it is a terminal system integration solution for satellite and eSIM IoT modules. More specifically, it describes a hardware terminal device that combines an IoT communication module with a satellite communication module. A dual-satellite architecture provides the terminal device with a global network to configure and read eSIM data files, thereby enabling the terminal device to have local cellular network connectivity. Ultimately, this achieves a globally integrated space-ground IoT system with zero configuration, zero pre-installation, and zero blind spots. This solution is widely applicable to global IoT devices, especially for global IoT device terminal integration in traditional cellular network coverage blind spots such as maritime, aviation, emergency rescue, and remote area deployments. It provides a complete, remote, flexible, and global solution in resource- and technology-constrained scenarios. Background Technology

[0002] my country's commercial aerospace industry has entered a period of rapid development in terms of technological breakthroughs, industrial agglomeration, and scenario expansion. As one of the business models of commercial aerospace, satellite IoT has further consolidated its infrastructure, technological capabilities, user scale, and application scenarios after years of development. Its integration with traditional IoT terminal devices is imperative, and IoT devices have fully entered the stage of global deployment.

[0003] In IoT applications, the traditional approach involves integrating an LPA (IoT Profile Assistant) into the device's communication module or main control MCU. Initial network connectivity is then established via a connection to a host computer's network or by pre-setting a global seed number to read and write the eSIM profile. This method suffers from unstable signals, low efficiency, and complex operation. There is an urgent need for a stable, globally adaptable, and universally deployable solution that integrates satellite and eSIM IoT modules into a terminal system. Summary of the Invention

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed and complete description of this application is provided in conjunction with the accompanying drawings and embodiments. The specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] In related IoT eSIM technologies, regardless of the type of terminal device, the provision of an initial network and the integration of communication modules of different devices with LPA (IoT Profile Assistant) to achieve the purpose of reading and writing eSIM profiles are all unavoidable drawbacks, including a large amount of R&D and adaptation work, high technical difficulty and cost, and a lack of emergency measures in the event of device disconnection.

[0021] According to embodiments of this application, a terminal device suitable for a wide range of global networking needs and a complete platform integration solution that can be remotely controlled are provided.

[0022] Figure 1 This is a schematic diagram of the overall architecture of the solution described in this application. The terminal device integrates a satellite + cellular dual-mode module, eSIM, and a main control LPA. The satellite module service adopts a dual-satellite primary / backup architecture, with Iridium as the primary and Orbcomm as the backup, achieving dual-network redundancy, service complementarity, optimal cost, and full coverage, resulting in a solution with optimal performance, reliability, cost, and power consumption. The satellite module provides the initial network for the device, connecting to the platform to perform basic eSIM-related tasks. After eSIM data configuration is complete, the terminal device switches to the cellular module network, connects to the management platform, and performs other related services.

[0023] Figure 2 This is a hardware schematic diagram of an example of the solution described in this application. The terminal device integrates the hardware schematic diagram of the satellite dual-mode module (satellite cellular dual-mode module, eSIM, main control chip, protocol processing system) provided in this application, and controls the communication module of the terminal device to communicate and interact with the eSIM through the main control chip. It should be noted that the logical method of the example in this application is not limited to the circuit design form.

[0024] Figure 3This is an automated flowchart illustrating the steps of the example described in this application. It details the complete automated remote task process from the initial state to successful operation of the terminal device. First, the terminal device powers on, initiates a self-test, and directly registers with the satellite using its hardware ID (IMEI / SBDN / Unit ID), establishing a satellite data channel. The device sends a profile task request to the management platform via the satellite network. The platform verifies the data and authenticates the device. After successful authentication, SM-DP+ distributes the profile packets via the satellite channel. The terminal device reassembles the received data packets, verifies the information, writes it to the eSIM via LPA, and activates the profile. It then obtains the IMSI and registers with the cellular network. At this point, the satellite-cellular converged network connection is active. Cellular network priority is given; if the device loses connection or signal for other reasons, the system automatically switches to satellite network mode, performs a self-test on the management platform, re-executes eSIM-related tasks, and connects the device to an available cellular network.

[0025] Figure 4 This is a schematic diagram illustrating the data flow of an example described in this application. The terminal device initiates a power-on self-test, registers with the satellite, and establishes a satellite connection channel. The terminal connects to the management platform via the satellite network channel for data authentication. The platform generates a profile data link using SM-DP+, and the SVNO Hub data packets are sent to the terminal via the satellite network. Upon receiving the data, the terminal verifies and reassembles it, writes it to the eSIM, and activates the profile configuration file. The cellular network is then registered, and the terminal device successfully switches to cellular mode.

[0026] Figure 5 This is a schematic diagram illustrating the application environment of the example described in this application. It shows the connection status of the network environment of the terminal device, satellite, and platform server.

[0027] According to the embodiments of this application, such as Figure 6 As shown, the detailed steps for the terminal system of the satellite and eSIM IoT low-power module to read and write profile data include:

[0028] Step S1: The device is powered on, the satellite module performs a self-test, registers the satellite channel, queries the task list from the platform through the satellite data channel, and sends a profile request.

[0029] In step S2, the platform receives the task request from the terminal device, performs data verification, generates a profile data link using SM-DP+, and distributes the data packets from the SVNO hub to the terminal device via the satellite channel.

[0030] In step S3, the terminal device receives and verifies the integrated profile data packet, writes and activates eSIM data, and the terminal program switches from the satellite module to the cellular module for network communication.
