One thing that could still go wrong is the Paging. I have noted at occasions

Maybe we aren't sending the CommonID with the mapping of TMSI<->IMSI in that case,
or somehow send it wrong?  I suppose it exists exactly for these situations, to tell
the RAN which IMSI the MS has, if it is not sent over the radio intreface.
