In order to realize the compatible communications system between digital TETRA and analogy MPT1327. Communications protocol between digital radio and control center is defined. Emergency call software flow for TETRA and MPT module is designed, and also state information sending and receiving for TETRA and MPT module is designed in this communication system. By comparing several solutions, switch methods between analogy TETRA communications and digital TETRA communications are designed including manual-switch and soft-switch. In the article, coding module of receiving and sending equipments in TATT analogy TETRA communications is described, so that it can be compatible with NOKIA network equipments and it also can improve the availability rate of the trunk system. In order to realize the integration of digital TETRA communication and analogy MPT1327 communications, double- frequency antenna system is researched.

通过几种车载电台解决方案比较，设计了相应的模拟集群通信系统与数字集群通信系统的切换方法，其中包括人工切换和软切换，实现了模拟与数字集群兼容的一体化移动列车调度电台解决方案；为了实现数字集群通信系统与模拟集群通信系统以及NOKIA与TAIT模拟集群通信系统之间的相互兼容，设计了新的数字车载电台与控制中心之间的通信协议；系统设计了用于数字集群通信模块的紧急呼叫通讯流程，以及设计了用于模拟集群通信模块状态信息发送与接收流程，以满足列车无线调度的运营要求；论文还论述了对TAIT模拟集群收发设备编码模块的改造，使之能与NOKIA的集群设备相兼容，提高了集群设备的利用率，为在NOKIA模拟集群通讯模块停产后寻找了一种可替代的兼容解决方案；为了实现数字集群通信系统与模拟集群通信系统设备的综合，论文还探讨了本工作所需专用的双频段的天线系统。

The spread spectrum communications are widely used in modern military communications, satellite communications, mobile communications and command, control, communication and intelligence( C~3I ) systems, because of its well multi-address access, low probability of interception, excellent performance of anti-jamming and secrecy.

扩展频谱通信作为新型的通信方式，由于其具有多址接入、低载获特性和较强的抗干扰能力，因此在现代军事通信、卫星通信、移动通信和指挥控制通信和情报(C~3I)系统中得到了广泛的应用。

Communications units used by the communications terminal are measured. An economic efficiency associated with the use of the terminal to communicate with the first and second mobile radiotelephone communications systems is determined from the measured communications units and the first and second stored critical values.

测量出通信终端所用的通信单位数后，根据测得的通信单位数和存储的第一和第二临界值就可以确定与使用终端与第一和第二移动无线电话通信系统的通信关联的经济效率。
