摘要
基于应急通信新需求对应急卫星网的要求,分析现有网络结构存在的问题,描述了一种网络集中管理、业务分层接入的树状网络结构的实现方式,该方式不仅能解决现网安全性低、人工操作复杂的问题,还具有提升卫星转发器带宽利用率的优点。
The satellite network requires innovation to meet the new demands of emergency communication.Based on the analysis of the existing network with low security and high operating difficulty,a new satellite network with centralized management and hierarchical access is described,which can not only solve the problems above,but also improve the utilization of satellite bandwidth.
