In satellite cellular communication systems, the radio frequency (RF) beams need to be managed to ensure proper balance between system performance, system capacity and system power consumptions. The system performance includes statistical distrib- utions of calls blocked and calls dropped. The signal carrier to noise ratio is also an important factor in the system performance evaluation. The system capacity is the number of calls the system can sup- port under varying environment conditions. Since satellite available power is limited, the system needs to properly arrange the beam activation schedules so that satellite power can be effectively utilized to provide maximum system capacity.
