This is actually very funny. According to the protocol, a RA update should
only be performed if the MS was/is already GPRS ATTACHED to this network
before. It clearly wasn't in this case, as the OpenBSC network never
offered GPRS support. Still, it tries it. That's why we're rejecting it.
Not sure if I understand it in detail, from my understanding an RA Update
is performed when the Routing Area has changed (or the periodic RA update
timer has expired). So if the phone is already attached to a network,
shouldn't we receive the RA update if it selects our new RA ?
