As I understand it ( and I freely admit this is just largely hearsay) "Basic" will be the equivalent of FIS, "Traffic" will be RIS, "deconfliction" will be RAS, and "procedural" will be ATC radar control for vectored ILS's etc.
Don't know what good a change of name alone will bring. The old names seemed perfectly self explanatory to me. But perhaps there is more to the master plan than I know (or understand.)
