To conserve system bandwidth, demand assigned multiple access (DAMA) systems are employed in the provision of voice services so that satellite channels are assigned only to those users engaged in calls. The conventional blocked-calls-dropped service discipline is appropriate to mobile telephone service in which performance is measured in terms of call-blocking probability. However, due to the unique traffic characteristics of mobile radio service, processing of batched calls using the blocked-cells-queued service discipline was found to be more advantageous. In the latter case, performance is measured in terms of call setup delay. Traffic engineering strategies are geared to a shared channel pool instead of two distinct fixed-size pools for each respective service. Shared-pool strategies promise better resource utilization by exploiting statistical fluctuations in traffic levels
