Method of managing access to a random-access communication network
First Claim
1. Communication management method for a random access communication network, characterized in that it comprises:
- dividing time intervals (IT) into time slots (T) each associated with an access time slot during which a terminal (UE) 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 (IT) into sub-intervals (SI) 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 (T) 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 (SI) a number, at least equal to the number of time slots (T) that it contains, of processing time windows (F) offset in time and of width substantially equal to that of a time slot (T), and deducing from the window (F) to which a received access request belongs at least one access delay of the requesting terminal (UE) relative to a reference and then sending an acknowledgement message to that requesting terminal (UE) at a moment selected as a function of that access delay so that it can receive it in a predefined acknowledgement time interval.

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 predefined acknowledgement time slot.
