The Private Identity is used to allow the UE access to the IMS network (for,
as you say, the purpose of registration, authorization, administration and
billing).
The Public Identity is used to identify a specific IMS user (there may be more
than one associated with one Private Identity). This information is conveyed to
the IMS CN during registration so that the network can know what IMS users that
are registered and available for service (e.g. a reception of a voice session).
As far as I can see, the Home Network Domain Name is also part of the SIP
registration procedure.
