                  Diameter Credit-Control Application
                     draft-ietf-dime-rfc4006bis-05

Abstract

   This document specifies a Diameter application that can be used to
   implement real-time credit-control for a variety of end user services
   such as network access, Session Initiation Protocol (SIP) services,
   messaging services, and download services.  The Diameter Credit-
   Control application as defined in this document obsoletes [RFC4006],
   and it must be supported by all new Diameter Credit-Control
   Application implementations.
