低轨卫星中信道预留策略的研究

Because of the low propagation delay and low transmit power, Low Earth Orbit(LEO) satellite plays a significant role in satellite communication. However, there are still many problems remaining in this field, such as new call blocking probability and handover call blocking probability. It is believed that the latter one is less desirable than new call blocking probability. In this paper, the channel reservation scheme based on arrival rate and call service rate has been investigated. Theoretical analysis and simulation results show our proposed method reduces the probability of handover call blocking.
