摘要
在LEO卫星通信系统中引入Ad hoc终端组网方式,提出一种同时基于Ad hoc方式与正常卫星业务信道远程通信的双模终端异构组网模型LADMNM,使热点小区内溢出的近距离业务可在卫星系统控制下进行类Ad hoc方式的通信;仿真实验证明:有效提高了LEO卫星通信系统所提供的总体话务流量,在相同点波束信道数下降低了实际呼叫阻塞率,提高了信道有效利用率,提高了LEO卫星通信系统的总体性能。
Lead to the introduction of Ad hoe terminal according to the LEO satellite communications system, propose a dual- mode terminal heterogeneous network model LADMNM based on the Ad hoc manner with the normal satellite business channel long - distance communications, so that hot spots within the overflow area close business can he conducted under the control of satellite systems like Ad hoc mode of communication in order to minimize the actual call blocking rate, increasing the overall satellite system traffic flow.
