一种隐性故障问题分析方法对发展TD-LTE的启示

摘要

从TD-SCDMA网络中的一项统计指标异常问题入手，发现了一种基站存在的硬件隐性故障。通过逐步查找问题的根本原因，并采取相应措施后，排除了隐性故障，使得该基站各项网络指标恢复正常。这一分析思路对本质上属于同类的TD-LTE网络中基站硬件隐性故障也有一定的借鉴和指导作用。%The implicit fault of hardware was found in the base station from an anomaly of a statistical index of the TD-SCDMA network. The fundamental cause of the problem was analyzed step by step. Then, the corresponding measures were taken to get rid of the implicit fault, which made various index of the base station back to normal. The analytical thinking can serve as reference and guidance to the implicit fault of base station’s hardware in the TD-LTE network.
