移动通信中,终端的移动及管理是无线通信管理的基本组成部分和主要职能。集群通信的应急联动功能,也集中体现在对终端设备的管理和调度功能上,因此移动性管理成为集群通信系统中必不可少的逻辑功能实体。本文主要分析TETRA集群系统(V+D空中接口协议)移动性管理(Mobility Management)实体的功能,并用C语言编程实现。源程序可以在windows以及Linux 等多种环境下运行。文中给出了基于ARM946ES内核的嵌入式系统平台上测试仿真结果及数据。 【关键词】 TETRA 移动性管理 信令 ARM The Analysis and Simulation of Mobility Management in TETRA Ma Hongli,Quan Jinguo,Lin Xiaokang (Graduate School at Shenzhen, Tsinghua University, Shenzhen ,518055) Abstract: The management of mobile station is part of wireless communications. With this , Trunked radio is efficient in urgency. This paper analyzes the entity of Mobility Management (MM) in Terrestrial Trunked Radio (TRTRA) Voice plus Data (V+D) and programs in C code. The program files are enable to run in several operating systems, such as Windows and Linux. Further, the platform embedded for simulation is based on ARM946ES and the numerical results are given.
