Abstract:
A method for providing service in a satellite communication system having at least one satellite and at least one user equipment (UE) device, the method comprising the steps of:projecting within a field of view (FOV) of a satellite a first set of antenna beams; receiving from the UE device to the satellite, using an uplink signaling channel within a signaling frequency band associated with the first set of antenna beams, a demand assigned multiple access (DAMA) request to transmit traffic data to the satellite; sending the UE device a DAMA response message; and directing a spot beam from the satellite to establish a traffic uplink for transmitting the data traffic from the UE to the satellite in accordance with a set of parameters included in the DAMA response message, wherein the gain of the spot beam exceeds the gains of each of the first set of antenna beams, and wherein the set of traffic uplink channels operate in a radio frequency band at least ten times greater than the signaling frequency band.
