Abstract
A device (D) is dedicated to communication management in a base station (SB) of a random access communication network. The device comprises processing means (MT) adapted i) to divide time intervals into time slots each associated with an access time slot during which a terminal (UE) is able to send an access request to the network and of width equal to the duration of an access request, ii) to divide said time intervals into sub-intervals (SI) including at least two consecutive time slots, iii) to designate in each sub-interval (SI) at least one prohibited time slot associated with a prohibited access time slot, iv) to define in each sub-interval (SI) a number, at least equal to the number of time slots that it contains, of windows (F) offset in time and of width equal to that of a time slot, and v), in the event of reception of an access request sent by a requesting terminal (UE), to deduce from the window (F) to which the access request belongs at least one access delay of the requesting terminal relative to a reference and then to determine from the access delay the time of sending an acknowledgement message to said requesting terminal (UE) so that it is able to receive it in a …
