Cdma Repeater On-line Monitoring System Based On The Embedded Research And Design,

Developing with the mobile communication,it brings more and more consumers to use the mobile phone,and the distibutings of the BTS are to be densest resolves the problems of the capability of the communication channels,but it also brings many negative influence,so as the distributings of the wireless signal being complicated.In some areas,the signal of the mobile phones are to be weak,and the mobile phones may wrok abnormalitely.So in recent years.the repeater are used more and more widely as the resolvent methods.The demands of the net organizing and optimizing or daily maintenance to the system is very strict because of the characteristic of the CDMA technology.As a part of the CDMA system,the repeater needs the system management for the system running well too. Whether the repeater system or the whole system needs a special management system, because the whole system is very complicated .So in this thesis, we research that the mointoring system of the CDMA repeater.In this research the task is to develop a monitoring system of the CDMA repeater. This system can dynamically inspect the repeater, thereby it can ensure that the repeater can run correctly and reduce disturbing the other communication facility as BTS, to make the whole network in the best optimizing state.For ensuring the repeater running correctly, so that it can adjust technologic targets and make a response to the fault of the system in time.This makes maintenance become easy.The design of the task is based on the Embedded System of ARM and Windows CE.net embedded operation system.Furthermore.the monitoring system has the ability of long-distance check and control,because of using the wireless CDMA modem to send information by RAS.In th is paper,firstly,discuss the basic principal of the CDMA communication system and the network management system. Then, come to the main research content of this project, and introduce the repeater monitoring system in details, in two ways of hardware structure and software design.
