Abstract

Mobile satellite communication systems are expected to be introduced widely during the 1990s, offering public telephone, private radio and data messaging services to a potentially large number of mobile users. Due to the narrow bandwidth in the L-band allocated specifically for land-mobile satellite services, demand-assigned multiple access (DAMA) is an important element in network design. A DAMA design approach is presented that addresses specifically the characteristics of a dispatch mobile radio network, in which the dispatcher is often the resource bottleneck. Preliminary analysis shows that the proposed design offers advantages in satellite channel utilization and DAMA signaling overhead compared to previously proposed designs
