Claim 19:
20. The space telecommunications system as claimed in claim 19, wherein the control data relate to the implementation of some or of all of the following mechanisms:
a mechanism of contention access control on the random uplink UL channel, including congestion control and stream control and taking into account the specifics of a satellite-based or HAPS station-based communication channel, with selection of timeouts and selection of a mode of transmission as a function of the type of data to be transmitted;
a specific power control mechanism suited to the uplink UL communication channel;
a Doppler drifts control mechanism;
an economizer mechanism for saving electrical energy of the at least one user space terminal based on the provision of a temporal duty cycle information item representative of a temporal sharing of one and the same downlink DL data channel carrier frequency by several logical beams served by one and the same satellite.
