摘    要:在低地球轨道卫星通信系统中,可根据低地球轨道卫星移动的特点,对信道预留策略加以改进,使其以小区中业务量的大小动态的调整预留的信道数量,降低切换业务中断概率。此外,将信道预留与新的到达业务排队策略相结合,可以进一步提高低地球轨卫星移动通信系统的整体性能。

关 键 词:低地球轨道卫星  移动通信  保护信道  排队

Guard Channel and Queuing Strategy in the LEO Satellite Communication System
Abstract:It is well known that the Guard channel is an important method for the mobile communication systems, which can greatly improve the system performance by decreasing the probability of forced termination. Guard channel is hard to be adopted in the terrestrial communication system because of unpredicted traffics. We change the strategy based on the characters of LEO satellite and get a good performance. Moreover, the queuing of the new traffic has been taken to improve the performance of the whole LEO satellite communication system.
Keywords:low earth orbit satellite  mobile communication  guard channel  queuing
