移動通信中，終端的移動及管理是無線通信管理的基本組成部分和主要職能。集群通信的應急聯動功能，也集中體現在對終端設備的管理和調度功能上，因此移動性管理成為集群通信系統中必不可少的邏輯功能實體。本文主要分析TETRA集群系統（V+D空中接口協議）移動性管理（Mobility Management）實體的功能，并用C語言編程實現。源程序可以在windows以及Linux 等多種環境下運行。文中給出了基于ARM946ES內核的嵌入式系統平臺上測試仿真結果及數據。

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.
