Abstract: In a network in which conflicts may arise because of simultaneous requests from several interlocutors, the invention provides for immediate granting of access to the network to a caller if, in a specified period of time prior to the request from the caller, no other request has been transmitted. If not, the controller of the network monitors the occupation of the network and, once it is no longer occupied, it verifies that no other request has been transmitted for a randomly specified period of time. If it is the case, it sends a verification message to the caller and, if it receives an acknowledgement of reception before a specified time, it grants him access to the network.
