TDM信道所能容纳地球站的数量是有限的,随着地球站数量的增多,一个TDM信道不能向所有地球站发送控制指令,因此本文提出了多TDM控制信道概念,从一个TDM信道扩展成多个TDM信道,实现地球站的分组以及在信道之间的切换.地球站根据参数设置信令中TDM信道选取字段的值,职守在相关的TDM上,系统对每个TDM,均考虑信道的备份.

The number of the earth stations in a TDM channel is limited, along with the increase of the earth station, one TDM channel can't send control injunction to all the earth station, so this thesis proposes a conception which is more TDM control channels, extending the TDM channel from one to more, achieving the grouping of the earth station and the switching between the channels. In the basis of the parameter, the earth station setting the value in the channel chooses field. On duty of the correlational TDM channel, the system takes the reserved of the channel for every TDM.
