In this paper we study the effect of the frequency reuse constraints inboth layers on the optimum channel allocation for a multi-cell/multi-spot-beam hybrid system. We adopt a specific multi-faceted cost function thatincorporates call-dropping due to unsuccessful hand-off attempts, andblocking of new calls. The minimization of the cost function is attemptedby choosing the optimal split of the total number of channels betweenthe cellular and the satellite layers. This complex optimization problemis solved by means of standard clock simulation techniques along with theadaptive partitioned random search global optimization technique and theordinal optimization approach.
