Communications management method in a random access communication network with long times for transmission of access request acknowledgements

A communications management method for a random access communications network, in which time intervals are broken down into access slots, and during an access slot, a network terminal transmits an access request to the random access communications network associated with a message to be transmitted by the network terminal, and said random access communications network comprises at least one processing device that causes a time required for transmission of an access request acknowledgement message acknowledging the access request to said network terminal to exceed a duration of the given access slot, the method comprising:

• periodically sending an acknowledgement message to said network terminal, said acknowledgement message comprising positive acknowledgement information associated with said access slot, wherein if the acknowledgement message acknowledging the access request is received during the access slot in which the access request was transmitted, the network terminal transmits the message associated with said access request.
