FAS测试是OSS系统中RNO测试的一种,可以记录下指定小区、指定频点的干扰情况,最多可以同时记录150个频点的干扰情况(当然,我们没有同时测试150个频点机的机会)。FAS的测试记录可以有以下用途:
1、监控测试小区现有频点的上行干扰情况;
2、通过上行干扰测试找到干扰最小的频点给当前小区;
3、通过改频前后两次测试结果的对比检查频率调整的效果;
跳频不会对FAS的测试结果有任何影响;
FAS测试的步骤:
1、设置与定义测试;
在开始测试之前,必须配置一个recording configurationg,包括:
•The cell set, defining in which cells to record.
•Frequency sets specifying which frequencies to measure. These frequencies will be monitored by each TRX of the cells specified by the cell set. Instead of specifying frequency sets, the frequencies can be specified to be those allocated to each cell (in the cell set).
•
ercentile value specifying which RXLEV value to report from the recorded interference distribution. Example: the 90th percentile value of a distribution is the value which 90 per cent of the samples are lower than or equal to.
•Time schedule consists of a start date and the number of recording periods to run, a time mask and a week day mask.
•yes/no indicator if intermediate results shall be reported after each recording period.
当两个测试中有共同的小区存在时,时间定义不允许有交迭,否则配置将不被接受;
同一时段内定义多于10个测试也不被接受;
