Abstract

The teletraffic performance parameters of a nongeostationary satellite system are estimated through analytical and simulation methods. In order to reduce the number of assumptions, the simulation tool that was developed emulates a mobile satellite system that is closer to the real thing. Parameters of interest include blocking, handover failure, noncompletion, and forced-termination probabilities. These are analyzed in terms of variations in satellite spot cells coverage, overlapping between cells, and in terms of a mobility factor. Additionally, the effect on the grade of service of different channel assignment strategies, for handover purposes, are investigated. The results show that the analytical work is in good agreement with the simulation outcome
