摘要
在WCDMA系统中,网络干扰不仅严重影响网络容量,同时也是影响客户感知的一个重要因素。采用华为无线网络控制器(Radio Network Controller,RNC)设备自带的天馈与干扰自动检测系统对现网的天馈网络干扰进行排查,可以通过远端数据分析检测天馈和干扰问题,如驻波、互调、容量受限干扰、外部干扰等,并通过近端的频谱扫描验证,输出干扰值及频谱特征,输出问题小区列表。该方案在天馈干扰排查中,排除了对设备的需求,缩短了上站次数及排查周期,降低了成本,能够有效提高天馈问题排查效率。
In WCDMA system, network interference not only affects the network capacity, but also one of the important factors affecting customer perception, this paper is mainly with the Guangxi branch interference antenna through HUAWEI RNC equipment with automatic detection of the antenna feed network on the current network interference system for investigation, through data analysis and remote antenna interference problems, such as standing wave detection can the system, intermodulation capacity, interference, external interference, and through the verification of the proximal end of the spectrum scanning, output value and interference spectrum characteristics, the output cell list. The scheme in antenna interference investigation, ruled out the demand for equipment, shorten the times and inspection cycle, reduce cost, can effectively improve the efficiency the antenna problem investigation.
