Management of communication between a terminal and a server of a network

A transmission device comprising a processor and a memory, wherein the transmission device is configured to:

• communicate with a gateway equipment forming a node of a telecommunications network via a first radio link using Long Range radio (LoRa) technology and to communicate with at least one server of the network via the gateway equipment;
• communicate with at least one terminal via a second radio link using LoRa technology, the device configured to receive, via the second radio link, a first connection request sent by a terminal contained in a list of terminals for which the transmission device has obtained management data;
• establish, following the reception of the first connection request, a secure communication session between the transmission device and the terminal,
• upon confirmation that the terminal is contained in the list of terminals, transfer, via the first communication link, at least one data message sent via the secure session by the terminal;
• upon reception of a data message intended for the terminal via the first communication link and upon confirmation that the terminal is contained in the list of terminals, transfer the message to the terminal via the secure session;
• receive, via the first communication link, a request to end management of the terminal;
• and
• remove the terminal from the list of terminals following the reception of the request.
