Abstract: In this paper, we consider communication networks with a satellite with multiple spot beams. We describe the structure and features of these networks and we investigate admission control schemes which optimize the network revenue if several services types with different revenues are present. We show that in some cases the blocking of some calls even if capacity is available can considerably increase the network revenue. We will fnrther prove that for systems with equal revenues, complete sharing, i.e., accepting calls on a first-come, first-served basis, is optimum.
