Mobile IP and Cellular Telephony

Charles E. Perkins
Nokia Research Laboratories

About the talk:

Mobile IP is under serious consideration in various working groups as a protocol component for a new cellular infrastructure. Groups within the IETF, 3GPP, and 3GPP2 all have related but distinctive perspectives on how to realize the still-nascent potential offered by Mobile IP. In this talk, I will describe some of these recent developments, concentrating on Mobile IPv6 and AAA (Authentication, Authorization, and Accounting). AAA is receiving a lot of attention related to Mobile IP and mobile networking, because service providers need authorization before they can establish a business relationship with mobile computer users that may roam into their area of service. This attention to the profit-making possibilities for mobile networking seems likely to provide a big boost for the deployment of Mobile IP. In this way, AAA will also provide additional impetus for creation of the wireless Internet. All major cellular standardization bodies are making Mobile IP and AAA services an integral part of the new cellular infrastructure. There is also a recognition that IPv6 is crucial for the eventual deployment of billions of IP-addressable wireless devices. I will end this talk by taking a look at the interactions between Mobile IPv6 and AAA, pointing out new areas needing work and making some guesses about the directions that may be taken within the IETF.
