Hi Neels,

thanks for outlining the roadmap.

Originally when we started this 3G related work, CSCN was "NITB without
BSC", i.e.  it included SMSC and HLR/AUC functionalities.  However, as
the VLR/HLR split is also coming to a close now, I'm not sure if we
shoul continue to call it CSCN, or if we should simply call it "MSC".
The only thing "unusual" for a MSC that it still contains at this point
(when both BSC and HLR/AUC have been moved out) is the SMSC.

So we migh simply move to a NITB that is split up in BSC, MSC/VLR and
HLR/AUC, and call the components OsmoBSC (exists already), OsmoHLR
(exists already) and OsmoMSC (which is still called CSCN).  Or we keep
calling it CSCN until the SMS has moved out?

Regards,
	Harald
