Based On TD-CDMA Coal Special Network Wireless Packe Data Mangement Research And Implementation

In recent years, with the rapid development of coal industry in economic growth, but Italso brings a lot of problems. For coal mine wireless communication system backward intechnology lead to issues such as emergency rescue capability, TD-coal mine was a Specialnetwork system to provide special network solutions. It is based on the public networkstability TD-SCDMA products. System ground and underground clingy mining productionoperation environment demand, the development of a comprehensive business coal mobileproduction scheduling systemThis thesis was in this context, mainly for TD-coal Special network system, especiallythe design of system session management PDP modification and release process carried onthe detailed design of software. Firstly, for packet data modification and release the twoprocess design principle, design idea is expatiated. Design principle is mainly based oninternal part of the module and module of the interface between relations and module functionmessages between processing method. Design train of thought is according to the system'sdemand analysis report and overall outline design of session management module report. Inthe whole system function and role of accurate positioning, and gradually completed.Secondly, modify and release process for PDP schemed of software process, namely thedesign of control module SM session management inside information processing, the functioncalls and external news response, forwarding functions research and implementation. Finally,PDP modification and release is test and analysis process. In the process of testing the testenvironment independently of structures, test cases to the planning and perfect andsummarizes and analyses of test results.
