• a message can be sent by D2 to Dl, in response to the message received by D2 and sent by Dl, indicating to Dl that the method P2 is at step D2 DECT and that Dl has the possibility of 'establish communication.
• the communication can be established by the device D2 with the device Dl.
• a message can be sent by D2 to Dl, in response to the message received by D2 and sent by Dl, indicating to Dl that the method P2 is at step D2 SND and that Dl has the possibility of 'establish communication.
• the user D2U can, once communication has been established with the user D1U, transfer the call by fixing the contact card of a third user.
• one of the two users can, during a call, set a new contact card in order to start a three or more conference.
• FIG. 5 illustrates the main steps of the method of establishing a communication intended for at least one terminal by analyzing the eye movements of a user, when the message requesting establishment of a communication M1 sent by the device D1 to device D2 is received by device D2 a few moments before method P2 is triggered.
• the environment being as described in support of Figures 1, 2 and 4.
• the message M1 requesting the establishment of a communication sent by the device D1 is received by D2 3 seconds before the method P2 is started on the device D2. That is to say before step D2 CAPT begins.
• the message has for example a validity period of 10 seconds. This duration can of course be configured, for example according to the services or the user.
• D2 will then start a stopwatch or a counter making it possible to determine whether the establishment request M1 sent by D1 is still valid.
• the method P2 validates the DECT step D2 and the message M1 is still valid, that is to say if the stopwatch started when the message M1 is received is less than 10 seconds, the communication C1 is established by the device D2 with device DI.
• the method P2 can send a request M2 to DI to establish communication.
• DI establishes the communication Cl ’.
