摘要
对于GSM网络中的设备故障,有些会触发相关故障告警,可称为显性故障。另外,有部分设备故障会影响网络正常运行,但却不会直接触发告警,这类故障称之为隐性故障,主要包括TRX、CDU、天线、背板、总线和各种连线设备,在软件、内部处理模块和连接方面等出现的问题。针对GSM网络隐性故障,首先要判断区分故障的类型,再根据实际工作经验将坏件替换或通知维护人员进行调测解决隐性故障。
In the equipment alarm, called dominant faults. In failures of GSM network, some addition, the other equipment would trigger the related fault failures would affect the normal operation, but not directly trigger the alarm, called recesive faults, mainly including TRX, CDU, antenna, backplane, bus, various attachment equipments, and connection problems occurred in software, internal processing module etc. For the recesive faults in GSM network, the first step is to distinguish the types of faults, and the second step to decide whether there would be a replacement in accordance with actual experience or to inform maintenance personnel for debugging the recessive faults.
