We don't really have/use any VLR. All we have is a subscriber table,
and each subscriber can have a completely different MCC/MNC as part of
his IMSI - we simply don't care. There is no distinction between
roaming and home network subscribers at all.
All we care about is if the subscriber.authorized field is 0 or 1 in
the sql database.
Regarding 'subscriber location' between multiple BTS: We simply store
the LAC of where the subscriber was last seen.
