Dynamic Channel Allocation Strategy of Satellite Communication Systems Based on Grey Prediction

Abstract

As the demand of communications continuously increasing, researches of satellite communication systems have received more and more attention. Among the studies, one of the important problems is access and handover, due to the high-speed movement of satellites and the mobility of the terminals. Meanwhile, the channel allocation strategy is a crucial part of the technology. Therefore, this paper studies the channel reservation strategy, thinking of how to reserve channels reasonably. Finally, a dynamic channel reservation strategy is proposed based on grey prediction to get better access and handover performance. This strategy dynamically adjusts the channel reservation number with the grey model prediction by predicting whether the calls need to handover or not, and then count all the calls that are possible to handoff.
