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(yīng)急聯(lián)動功能，也集中體現(xiàn)在對終端設(shè)備的管理和調(diào)度功能上，因此移動性管理成為集群通信系統(tǒng)中必不可少的邏輯功能實體。本文主要分析TETRA集群系統(tǒng)（V+D空中接口協(xié)議）移動性管理（Mobility Management）實體的功能，并用C語言編程實現(xiàn)。源程序可以在windows以及Linux 等多種環(huán)境下運行。文中給出了基于ARM946ES內(nèi)核的嵌入式系統(tǒng)平臺上測試仿真結(jié)果及數(shù)據(jù)。

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.
