TETRA交换管理中心系统架构设计

Design on System Architecture of TETRA Mobile Switch Center

针对陆地集群无线电(TETRA)数字集群交换管理中心设备研制需求,提出了一种TETRA交换管理中心系统架构设计。描述的系统架构设计由中心控制器分系统、互联分系统、安全管理分系统、网络管理分系统和网络传输分系统5部分组成。在系统架构设计的基础上,分析了TETRA交换管理中心研制中面临的空口标准分解和中心控制器分系统软件设计两大核心问题,并给出了相应方案。采用软仿真的测试软件系统,对系统进行了基本功能及鲁棒性测试,验证了设计的可行性。

For the R＆D requirements of Terrestrial Trunked Radio （TETRA） digital trunked radio mobile switch center equipment,a design on system architecture of TETRA mobile switch center is presented.In the description of system architecture design, five component parts are introduced,such as center control unit subsystem,interconnection subsystem,security management subsystem, network management subsystem and network transmission subsystem.Based on system architecture design ,two key problems countered in the R＆D of the TETRA mobile switch center are analyzed, such as air interface standard decomposition and center control unit subsystem software design, and the corresponding solutions are provided.By adopting simulation test software system, the basic functions and robustness of system are tested, and the feasibility of design is verified.
