Actually, I've interpreted Miguel's "timeslot" as follows :

Any time a user does not accept a session returned by CCBS within a
given timeslot his place in queue is removed, unless he is busy.

Any time a user is busy when a session returned by CCBS is delivered, he
keeps his place in queue. Other users in queue, if any, can be served.
(this last scenario is known as "suspension")

Would that be ok ?

The "CCBS/CCNR request" as I read it in the draft, is used as "Please
add me to the CCBS/CCNR queue of the callee": it's a request to monitor
a user status changes, not a call. If it's not clear enough, we could
replace it in the requirements with "CCBS/CCNR subscription": would that
be easier or is it even more confusing?

The requirement is not strictly for the caller to be notified of the
callee status, nor for him to setup the call, in my opinion it  should
just be:

  The CCBS/CCNR simulation service should be able to deliver a
communication to the caller, when the service-specific condition related
to user state is met. Any communication performed as a result of a
CCBS/CCNR should be distinguishable from regular calls.
