A method and a system for multi-user transmission in a network, comprising at least on network control center NCC and one or more terminals, wherein the method comprises at least the following steps: determining the number of 4D-TDMA carriers as a function of the number and needs of the terminals, determining the type (SCPC or TDMA) and frequency band Bi of each of the 4D-TDMA carriers as a function of the terminals transmitting on the carriers, for each frame, dividing the band B into PTDMA transmission channels and into PSCPC service channels, each channel consisting of frames comprising a plurality of slots, STDMA slots and SSCPC slots, dynamically allocating a plurality of slots of a 4D-TDMA carrier according to the services required by each terminal, configuring the coding and modulation scheme of each slot by taking account of the quality of the received signals.

In the field of satellite communication systems, a method is provided for managing communication resources allocated by central control equipment to the various terminal communication devices within a global satellite communication system. In particular, the management of communication resources by way of the monitoring of the equivalent isotropically radiated power transmitted by a terminal of the satellite communication system is provided.
