摘要
为了支撑GSM系统中的无线网络分析和优化,应用爱立信GSM系统OSS统计中的BAR和MRR数据、ICM干扰带数据以及直放站监控系统数据开发了频率干扰和上行干扰分析软件。软件包含了数据编辑、导入、解析、分析、导出和地理化显示等各个过程,以方便用户的使用。分析中生成的数据还可用于自动频率规划。在软件实现中,采用了OLE自动化方法调用地理信息系统,并给出了因BSIC解码错误对邻小区名进行自动修改的方法。应用表明,该软件可有效地发现网络中的频率干扰和上行干扰。
In order to support the radio network analysis and optimization in GSM.system, the frequency interference and uplink interference analyzing software is developed using the BAR and MRR data, ICM interference band data from the OSS statistic in Ericsson GSM system and data from the repeater monitoring system. The software includes all the procedures like editing, import, parsing, analyzing, export of the data and geographic display to make it convenient for the users to use. The data generated during analyzing can also be used for automatic frequency planning. In the implementation of the software, the OLE automation method is used to invoke the GIS and a method of modifying the names of the neighboring cells automatically due to the wrong decoding of BSIC is given. Applications indicate that the software can disclose frequency interference and uplink interference in the network efficiently.
