Dynamic generation of unique identifiers in a system of connected things

A method in a server of a network for providing to a device gateway an identity of a service provider network associated with an Internet of Thing (IoT) device connected to the device gateway for the purpose of creating a unique IoT device identifier, the method comprising:

• receiving a request message from the device gateway for obtaining the identity of the service provider network associated with the IoT device, the request message comprising a manufacturer IoT device identity;
• determining an association between the identity of the service provider network and the manufacturer IoT device identity;
• and
• validating the association, and conditional to a successful validation sending a message to the device gateway for creating the unique IoT device identifier, the message comprising the identity of the service provider network and the manufacturer IoT device identity.

A device gateway configured to dynamically create or update a unique Internet of Thing (IoT) device identifier, the device gateway comprising a circuitry configured to:

• obtain an identity of a service provider network associated to a manufacturer IoT device identity of the IoT device;
• if the unique IoT device identifier is not already available, create the unique IoT device identifier comprising a concatenation of the identity of the service provider network and the manufacturer IoT device identity;
• if the unique IoT device identifier is already available, update the identity of the service provider network of the unique IoT device identifier;
• and
• store the unique IoT device identifier.
