Network Working Group Request for Comments: 4004 P. Calhoun Category: Standards Track Cisco Systems, Inc. T. Johansson Bytemobile Inc C. Perkins Nokia Research Center T. Hiller, Ed. P. McCann Lucent Technologies August 2005 Diameter Mobile IPv4 Application 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 and status of this protocol. Distribution of this memo is unlimited. Copyright Notice Copyright (C) The Internet Society (2005). 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. Table of Contents 1.
