集群通信在指挥调度及抢险救灾中发挥中重要作用，目前地面集群通信网络的覆盖范围有限，在处理有些紧急事件时可能会超出网络覆盖。依托通信对距离不敏感的卫星移动通信，在GMR-1标准基础上实现组呼呼叫业务功能，可以扩大集群通信的覆盖面积。对空闲模式下组呼通知过程进行了研究，对处于空闲模式下的移动台使用简化的 NCH 监听机制做了概述，最后提出了组呼通知信道的配置方法，计算得到 NCH 信道可以支持的话务量，与现有的 GSM 网络通信的相比具有更高的寻呼效率、可以承载更大的用户数量。

Trunking Communication plays an important role in dispatching and disaster relief. At present, the coverage of ground cluster communication network is limited, thus the network coverage may be excee-ded in the treatment of some emergencies. Relying on the mobile satellite communication unsensitive to the distance, the group call service function based on the GMR-1 standard could be realized,which would ex-pand the coverage area of the trunking communication. This article studies the notification procedure in idle mode and the MES reduced NCH monitoring mechanism, proposes a solution of NCH configuration,and then calculates the traffic that would be supported. Compared with the existing GSM network communica-tion,this mechanism has higher paging efficiency and larger users.
