Blocking and handoff performance analysis of a LEO satellite/terrestrial hybrid system

This paper deals with resource management strategies in a LEO (low Earth orbit mobile satellite) satellite/terrestrial hybrid system. A terrestrial cellular mobile network enhanced by a LEO system is given out with the consideration of traditional handoff requests. Moreover, we model inter-beam handoff requests. We also discuss the difference about handoff procedures and mobility-models between terrestrial cellular cells and LEO umbrella cells. An analytical approach has been developed to compare the terrestrial cellular system with hybrid system. The results of blocking probability, forced termination probability and the average handoff number have been given out in figures.
