Abstract
In an IoT device data management method, an IoT device sends a data report message to a device management server, to report a device identifier of the IoT device and a SIM card identifier of a SIM card in the IoT device. The device management server stores the device identifier and the SIM card identifier, and may further synchronize the device identifier and the SIM card identifier to a connectivity management server. In this way, the device management server establishes and maintains a correspondence between the device identifier of the IoT device and the SIM card identifier.
Claims20
A method implemented by a device management server and comprising:
- receiving, from an internet of things (IoT) device, a data report message comprising a device identifier of the IoT device and a first subscriber identity module (SIM) card identifier, wherein the first SIM card identifier is of a SIM card in the IoT device;
- and
- storing the device identifier, the first SIM card identifier, and a correspondence between the device identifier and the first SIM card identifier.
A method implemented by an internet of things (IoT) device and comprising:
- obtaining a device identifier of the IoT device and a first SIM card identifier, wherein the first SIM card identifier is of a SIM card in the IoT device;
- and
- sending, to a device management server, a data report message comprising the device identifier and the first SIM card identifier.
A method implemented by a connectivity management server and comprising:
- receiving, from a device management server, a data synchronization message comprising a device identifier of an internet of things (IoT) device and a first subscriber identity module (SIM) card identifier, wherein the first SIM card identifier is of a SIM card in the IoT device;
- and
- storing the device identifier, the first SIM card identifier, and a correspondence between the device identifier and the first SIM card identifier.
