A method for updating a table of correspondence between a logical address associated to a user unit in a communication network and a unique identification number associated to a user unit of a group of user units managed by a management centre, a method in which messages are exchanged between said management centre and at least one specific user unit of said group by means of said communication network, these messages being forwarded to the specific user unit using the logical address of said user unit in said network, the method comprising:

  • searching, in the table of correspondence, for the logical address of the user unit in the communication network corresponding to the unique identification number of the specific user unit;

    sending messages to the user unit having the concerned unique identification number, to the logical address corresponding to said communication network;

    sending, in the case of incorrect reception of the messages, a request containing an identifier of said specific user unit, this request being sent to all or a part of the user units forming said group;

    detecting a return message of a user unit whose unique identification number corresponds to said identifier contained in the request;

    determining the logical address in said network, used by the user unit having transmitted the return message;

    verifying the logical address by establishing a communication between the management centre and the user unit and authentication of the specific user unit by the management centre;
