Summary:
We consider a Low Earth Orbit (LEO) Mobile Satellite System (MSS) with “satellite-fixed” cells thataccommodates new and handover Poisson arriving calls of different service classes. By modelling the LEO-MSS as a multirate loss system, we provide an analytical framework for the recursive calculation of call blocking and handover failure probabilities under the Fixed Channel Reservation (FCR) policy. In the FCR policy, an integer number of channels is reserved in order to benefit calls of high channel requirements. The loss model under the FCR policy does not have a Product Form Solution (PFS) for the steady state probabilities. However, we show that the channel occupancy distribution can be calculated via an approximate but recursive formula. Simulation results verify the accuracy of the proposed formulas.
