摘要：

Analytical models for low earth orbit mobile satellite systems (LEO-MSSs) should consider service time correlation in adjacent satellite spot beams. This letter presents a simple analytical framework for the efficient performance evaluation of new and handover services in LEO-MSSs with correlated service times. When the fading channel is temporally correlated, channel characteristics in the preceding and succeeding spot beams do not change dramatically, especially for services with short transmission times. A closed-form solution of the correlated queue service time is derived using probability generating functions whose moments are used to derive the blocking probabilities of handover and new services. The system is then modeled as a queuing system with correlated service time and its performance investigated.
