Hi,

In addition, PUR/PUA command is also used in the draft-johansson-aaa-diameter-mm-app-01.txt for (-/re/de-) registering the user, either from the AAAH or the client. From the logical point of view the profile updating and (-/re/de-) registration are different operations and therefore it would be quite natural to separate the profile updating from the registration. 

This could be done by specifying different command codes for the profile and the registration related operations.

Best Regards, Jaakko
