I find the measurement report of OpenBSC very difficult to read, because it is not possible to distinguish the various phones.
Of course, it is possible to filter the log (logging filter imsi ...), but sometimes, as in my case, it is necessary to get the measurement reports of many phones at the same time. In this case, it is not possible to know which phone generate which report.
I create a patch to solve this problem. With this patch, the measurement reports contain the lchan in which the call (or SMS) runs (just as information), the IMSI and the extension of the phone.
If you are interested, here is it!
