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.
