4、到如下目的：监测网络性能； 故障（尤其是通常手段较难发现的故障）排察； 网络调整后的效果分析；6ssI由于它是OSS平台下的优化工具，下面的图示描述了 mrr在OSS平台下的工作原理从当前的实际应用经验看， MRR 作为网络调整后的效果分析工具是目前其他无线调查手段无 法比拟的，因为它可以提供被调整对象或区域的最全面、最重要的所有无线特征参数的前后对 比，而且我们可以根据需要调查对象的实际情况决定调查的范围和时间。1个OSS系统同时支持的mrr统计：10个；Uppgjord (aven faktaansvarig om annan) - Prepared (also subject respo
