hi,

i like to check out the measturement report feature of GSM. the A-bis protocol shows measurement report indications, but i can't see any request to turn it on. on the BCCH it is turned on, as far as i can see in the bsc_hack.c. what do i miss? (neighbor cell frequencies?)

actual measurement reports are sent all the time, as we turn them on by BTS/TRX configuration attributes. I can observe them very clearly as soon as any dedicated channel between MS and BTS is established.

We do not get any information about neighbor cells from the MS, since the BCCH of our BTS does not send information about known neighbor cells. Only if we put some ARFCN's in there, the MS will actually scan for the CCCH of those and report the corresponding measurement values.
