Status of This Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state

Abstract

   This document specifies a Diameter application that allows a Diameter
   server to authenticate, authorize and collect accounting information
   for Mobile IPv4 services rendered to a mobile node.  Combined with
   the Inter-Realm capability of the base protocol, this application
   allows mobile nodes to receive service from foreign service
   providers.  Diameter Accounting messages will be used by the foreign
   and home agents to transfer usage information to the Diameter
   servers.
