A Dynamic Channel Reserve Strategy for LEO Communication System

A dynamic channel reserve strategy for LEO communication system with spot-beam is proposed. It does not need to record the location of the mobiles. Using the characteristic of mobile, we proposed a way to predict the number of channels those should be reserved in a spot-beam by the distribution of subscribers between spot-beams. The comparison between our strategy and the fixed channel reserve strategy through simulation shows that the former can automatically adjust the number of reserve channels, and improve the performance of the system.
