Patent ID: 7580700

Claim:
A communication management method for a random access communication network, the method comprising: by a gateway of the random access communication network, dividing time intervals into time slots each associated with an access time slot during which a terminal can send an access request to the network, and of selected width greater than or equal to the duration of an access request and then divide those time intervals into sub-intervals including at least two consecutive time slots and prohibit the terminals from sending access requests during at least one of the access time slots associated with the time slots of each sub-interval at the same time as authorizing them to do so during non-prohibited access time slots, defining in each sub-interval a number, at least equal to the number of time slots that said sub-interval contains, of processing time windows offset in time and of width substantially equal to that of a time slot, and deducing from the window to which a received access request belongs at least one access delay of the requesting terminal relative to a reference and then sending an acknowledgement message to that requesting terminal at a moment selected as a function of that access delay so that said requesting terminal can receive said acknowledgement message in a predefined acknowledgement time interval.
