基于ARM的WCDMA数字光纤直放站监控终端的设计

Design of WCDMA Digital Fiber Repeater Monitor Terminal based on ARM

针对现有直放站监控终端可靠性不高、实时性不强和软件升级不便等问题,设计一种稳定可靠、支持GPRS远程升级并且容易扩展的解决方案。以嵌入式微处理器为核心,使用WCDMAModem与远程监控中心OMC(Operate Mainte-nance Center)建立无线连接,支持OMC通过短信和GPRS方式对WCDMA数字光纤直放站的配置管理、告警管理、性能数据采集和软件升级。

In order to improve some deficiencies of current repeater monitoring terminal such as low reliability, non-real-time, and inconvenience in softwaring upgrading, a reliable solution supporting GPRS upgrade and extension is designed. In this solution, Embedded microprocessor is the core, and a WCDMA Modem is used to communicate with Operation Maintenance Center （OMC）. OMC can carry out configuration management, alarm management, performance data sampling and software upgrade via SMS or GPRS.
