TD-SCDMA煤炭专网中GMM的研究与实现

Research and Implementation of GMM in TD-SCDMA coal private network

为了降低矿难,避免煤矿系统的灾难发生,根据煤矿自身安全生产条件的特点,采用组建适用于煤矿企业的TD-SCDMA通信专网的方法,研究煤炭行业通信专网的原理及实现方法。研究结果表明:GMM(GPRS移动性管理)支持用户的移动性管理功能,对整个TD-SCDMA煤炭专网有着重要的意义,针对GMM模块可以采用理论分析与实际测试的方法,运用模块化的设计理念实现了专网系统中的GMM功能。该成果对以后煤炭行业通信网络的建立与应用具有一定的参考价值与指导意义。

In order to reduce mine accident and avoid mine hazard in mine system,according to the characteristics of mine safety and production,this study investigates the principle and implementation method of communication private network in the coal mining industry using TD-SCDMA communication special network method.The results show that GMM（GPRS mobility management） supports the users＇ mobility management function and is of significance to the whole TD-SCDMA coal private network.Theoretical analysis and practical test method have also been conducted on GMM module.In addition,using a modular design concept,the GMM function can be realized in private network system.The study results provide some reference value and guidance for the future establishment and application of communication network in the coal mining industry.
