Description

[0001] Field of technology to which the invention relates

[0002] The invention relates to telecommunications technologies, specifically to systems for managing embedded SIM card (eSIM) profiles in Internet of Things (IoT) devices, such as routers and other communication devices. The system enables centralized management of eSIM profiles, including remote activation, deactivation, switching between mobile operators, and other operations.

[0003] Technical level

[0004] The main problem with disparate IoT devices is the difficulty of integrating and managing them. Different devices may use different communication protocols and standards, making it difficult to interact and integrate them into a single system. Centralized management of a large number of disparate devices is also difficult, which can lead to problems with firmware updates, status monitoring, and troubleshooting. Difficulties in standardizing data from different devices also complicate its aggregation and analysis, reducing the effectiveness of the collected information.

[0005] Technical solution known: Peplink routers (https: / / www.peplink.com / products / mobile-routers / ) equipped with an eSIM chipset can use both BYO eSIM and Peplink eSIM. BYO eSIM stands for Bring Your Own eSIM. This means you can use up to two carrier eSIMs for quick and convenient switching.

[0006] Out of Band Management (OOBM) - Access to everything behind the Peplink router is integrated into one platform, no matter what or where it is.

[0008] Features:

[0009] 2-SIM ports + eSIM M2M support. The device is equipped with a dual SIM failover function.

[0011] Remote Management System

[0012] The package includes RutOS (OpenWrt based Linux OS) operating system with advanced software capabilities such as Modbus, SNMP, TR-069, NTRIP, MQTT, and many VPN services.

[0013] The IoT Hub Platform solution from MTS (https: / / business.mts.ru / moskva / iot-platforma) is also well-known; it supports integration with multiple operators and eSIM management. The solution works with any communication networks and protocols, including MQTT, CoAP, and NIDD, as well as with any type of smart device: from simple sensors and meters to engineering systems and devices with digital Modbus or Ethernet interfaces.

[0020] The declared technical device has a number of advantages compared to the specified analogues.

[0021] Disclosure of the essence of the invention

[0022] The technical result of the invention is the ability to centrally manage eSIM profiles on any IoT device. All IoT devices are managed using a single platform and a single interface. This enables integration with any telecom operator. This increases the cost-effectiveness of management by reducing logistics and production costs. It also enables management both locally and remotely. A router with an eSIM, managed from the platform, can automatically switch between eSIM profiles to ensure uninterrupted internet connectivity across countries or regions.

[0023] The technical result associated with the possibility of centralized management of eSIM profiles on any IoT devices, while the management of all IoT devices is carried out using a single platform, through a single interface, with the possibility of integration with any telecom operators, is associated with the design of the stationary router device, namely the use of a built-in universal eUICC card.

[0024] The technical result associated with increasing the economic efficiency of management by reducing logistics and production costs is achieved due to the ability to centralize remote management of any eSIM profiles in IoT devices.

[0025] The technical result, enabling both local and remote management, is achieved through the design of the stationary router and the presence of a unified remote management platform within the system. Remote management of eSIM profiles enables automatic switching of mobile operators for routers and other IoT devices without the need to physically replace SIM cards.

[0026] The technical result related to improving security is achieved due to the presence of built-in security functions SGP.21 / 22 / 31 / 32.

[0027] Fig. 1 shows the general operation diagram of the claimed system. Fig. 2 shows the structural diagram of the elements of the claimed system. The key element of the system is a stationary router containing a local user interface (1), software for managing cellular operator profiles on the router (2), by means of which management is carried out either locally or remotely using the remote management platform (6), containing the OpenWT or Linux operating system (3), an eSIM chip - an embedded universal eUICC card (5) for identifying a subscriber in the operator's network using the provided profile, the hardware (4) of which is represented by a processor, memory, motherboard and modem. User identification occurs due to the presence of the eUICC device (5), which, via the ES9+ interface (8), receives information from the SMDP+ server of the cellular operator (7).There are also ES10a and ES10b interfaces (9), which link the fixed router software and the eUICC device (5) for local management, and an ESipa interface (10), which links the fixed router and the remote management platform (6) for remote management.

[0028] System components:

[0029] 1. eSIM IoT Remote Manager Platform:

[0030] Enables remote management of eSIM profiles on IoT devices. Includes interfaces for working with mobile operators and managing eSIM profiles.

[0031] Implemented via cloud servers and uses GSMA standards to ensure compatibility.

[0032] The platform provides capabilities for monitoring, managing, activating and switching eSIM profiles on connected devices.

[0033] 2. Router with eSIM:

[0034] An eSIM-enabled IoT device that provides connectivity to mobile networks. Connectivity and switching between mobile operators are managed by the platform.

[0035] The router can be used to provide wireless internet in mobile or remote environments, such as transportation, drone systems or other IoT solutions.

[0036] Built-in mechanisms allow the router to automatically switch between operators to minimize roaming costs and ensure maximum connection speed.

[0037] Implementation of the invention

[0038] Installing eSIM profile:

[0039] The user uses the remote management platform or the router's local interface. A subscriber profile link and activation code are transmitted to the router via the ESipa interface (10). Inside the router, software (2) uses the ES10a and ES10b interfaces (9) to exchange information with the eUICC chip (5).

[0040] The router software (2), using the received data, requests a profile from the mobile operator's SM-DP+ server (7) via the ES9+ interface (8). The mobile operator's SM-DP+ server (7) verifies the GSMA certificates on the eUICC chip using the ES8+ interface. If the verification is successful, the SM-DP+ sends the profile to the router software (2) via the ES9+ interface (8).

[0041] The router software (2) downloads the profile to the eUICC (5) via the ES10a and ES10b interfaces (9). The eUICC (5) installs the profile, activates it, and registers with the operator's cellular network. The eUICC (5) then sends a completion notification to the IPA router software (2).

[0042] The router software (2) notifies the user that the profile download is complete via the remote management platform or the router's local interface. The IoT device then appears in the system and can be managed and its operating status monitored.

[0043] Switch between operators:

[0044] The platform monitors connection quality and roaming conditions for the connected device. If necessary, it remotely switches between mobile operators to optimize costs and connection quality.

[0045] Monitoring and control:

[0046] The platform provides an interface for monitoring the status of connected devices, managing their eSIM profiles, as well as data usage and carrier statistics.
