Hi,
I'm reading the book "Die GSM-Dm-Kanäle im Dialog" by Joachim Göller, and I learned, that a mobile phone sends, about every second, a MEASUREMENT REPORT to the station, where it is logged. In this report the mobile sends the signal power of the cell, where it is logged, and of other neighborhood cells. With these signals, I can measure the distance of the mobile from my cell(s).
But I don't understand how can I get this values using OpenBSC.
It only does that when in an active dedicated channel (either a call or a sms or some other transaction). If you enable the debug for the DMEAS (either in the console or with the -d option), you should see those reports.
Also, it sends reports only for neighbor cell of your network (as specified in the BCCH SI messages).
Cheers,
Sylvain
