GSM通信系统受到上行干扰会增加系统的掉话率，同时基站覆盖范围减少，通话质量和网络性能指标受到严重影响，可能导致通话出现断续、杂音等，影响用户通信质量。引起上行干扰的主要原因有：基站设备中硬件故障，内部干扰，外部干扰等。上行干扰的来源大都是由于直放站故障、外部干扰器（屏蔽器）干扰、不同网络间干扰、民用设备干扰等原因引起。通过一次通信故障处理案例，阐述了天线隐性故障导致的上行干扰情况。

The uplink interference of GSM communication system has become a problem which can not be ignored. Uplink interference will increase the system′s call dropped rate, while reduce the coverage of base station. The call quality and network performance indicators have been seriously affected, it may make a call appear intermittent, and noise, etc. also can affect the communication quality. Uplink interference is caused by two main reasons: the base station equipment hardware failure, internal interference, external in-terference and so on. In previous work, the uplink interference sources are mostly due repeater failure, ex-ternal interference, device ( jammers) interference, different networks interference and civilian equipment interference. This article describes the status, causes and processes of the uplink interference. By a process of a fault which discovers hidden failures can cause antenna uplink interference.
