When you do your 3GPP/BBF interface specification (or update some existing 3GPP/BBF specification) define the translation/interworking in that spec. IMHO that's where it belongs since the logic & implementation will anyway be very deployment specific. Defining a translation for anything than very basic & simple authentication has proven to be just handwaving in IETF space. - Jouni On Feb 12, 2014, at 11:14 PM, Behcet Sarikaya <sarikaya2012@gmail.com> wrote: > Hi Jouni, > > RADIUS - Diameter interworking is important for fmc (fixed mobile convergence), as you know the fixed network uses RADIUS and 3GPP uses Diameter.
