Abstract
A method of performing cellular digital radiocommunications in a TDMA system implemented within a network of geographical cells through which mobile stations (SM1 to SM22) travel, a base station being associated with each of the cells, a mobile station communicating via the base station that is associated with the cell in which the mobile station is located. Each each of the frames in the up transmission direction, from the mobile stations to the base station, contain at least one shared time slot (IT6) which is allocated to at least two distinct mobile stations (SM7 to SM22). For each shared time slot (IT6), the system has a list (31) of the active mobile stations, an active mobile station being a mobile station to which the shared time slot is allocated, and which satisfies at least one predetermined selection criterion. For, each frame in the up transmission direction, the system associates each shared time slot with a mobile station chosen from the list of the active mobile stations associated with the shared time slot, the choice being made by using a predetermined strategy.
