Abstract
An IoT management system may be configured to provide unified remote SIM provisioning across mixed Internet-of-Things (IoT) device fleets while simultaneously ensuring resilient profile delivery over satellite links. A hybrid protocol gateway interfaces with both modern SGP.32 (Secure Global Platform 3.2) and legacy SGP.02 (Secure Global Platform 2.0) devices, translating management commands and performing on-the-fly profile format transcoding to accommodate heterogeneous endpoints. A delay-tolerant networking (DTN) gateway may be configured to ensure reliable profile delivery over intermittent satellite connections by fragmenting profile payloads into bundles, scheduling transmissions based on satellite visibility windows, and supporting multi-pass delivery for enhanced reliability.
Claims15
A method of managing a SIM profile on a legacy IoT device using a hybrid protocol gateway, the method comprising, by the hybrid protocol gateway:
- receiving a remote provisioning command over an IP control interface from a remote provisioning module, the command specifying a target identifier associated with a secure chip of a device;
- determining a device type and current state of the device;
- mapping the command to a corresponding legacy command;
- generating legacy code compatible with an eSIM card of the device;
- generating an SMS message including the legacy code;
- and
- transmitting the SMS message to the device, wherein the device is configured to execute the legacy code to implement the remote provisioning command.
