Teletraffic Loss/Queueing Models in LEO Mobile Satellite Systems: a Short Survey

In this paper we present teletraffic loss/queueing models that can be applied in low earth orbit mobile satellite systems (LEO-MSS) with "satellite-fixed" cells for the determination of call blocking probabilities of new and handover calls. We study two different model categories: a) those that focus on single-rate traffic where calls belong to a single service-class and require one channel for service and b) those that focus on multirate traffic where the LEO-MSS accommodates many service-classes whose calls may require more than one channels for service.
