Abstract: This method relates to the control of the information stream in a cell constituted by several radio channels (C.sub.1) and (C.sub.2), each connecting terminal stations (T.sub.1l to T.sub.1m) and (T.sub.2l to T.sub.2n) to a main station (1) of the cell. In order to assign the ascendent path of a radio channel to a terminal station, the main station transmits in this channel a code signal S.sub.o, whereupon the terminal stations transmit calls to be used in call time windows each with an associated priority level. The main station transmits, in answer time windows, code signals dependent upon the received signals: a code signal S.sub.3 if the received signal is a distinct call, to give a terminal station the authorization to use the ascendent path, or a sequence of code signals S.sub.1 or S.sub.2 if the received signal contains, simultaneously, several calls, or does not contain any call. Dependent upon each code signal S.sub.1 or S.sub.
