引言在战术作战领域内、若干作战命令和控制功能都只有在有了移动电话业务的条件下才能有效地完成。移动电话业务在性能和方法方面的最大效率应当与提供给固定用户的业务相同。必要的无线电设备的设计工作受到限制是由于需要保存频谱。根据防务方针和国家的COMSEC目标,应当设计出MSE设备,使之有可能建立以移动电话用户到交换系统的固定用户所使用的终端机之间的保密线路。如TRI—TAC体系所规定的那样、移动用户设备(MSE)分为三种基本设备、即移动用户总局(MSC),移动用户终端(MST)及存取装置
INTRODUCTION In the field of tactical operations, a number of operational commands and control functions can only be accomplished efficiently with the mobile phone service available. The maximum efficiency of the mobile phone service in terms of performance and method should be the same as that provided to a fixed user. The necessary design work for radio equipment is limited due to the need to preserve the spectrum. In accordance with the defense policy and national COMSEC objectives, MSE equipment should be designed to make it possible to establish a secure line between terminals used by fixed users of mobile telephone users to the exchange system. As stipulated in the TRI-TAC system, mobile user equipment (MSE) is divided into three basic devices, namely the mobile user terminal (MSC), the mobile user terminal (MST) and the access device
