               Update Notifications for Proxy Mobile IPv6

Abstract

   This document specifies protocol enhancements for allowing the local
   mobility anchor in a Proxy Mobile IPv6 domain to asynchronously
   notify the mobile access gateway about changes related to a mobility
   session.  These Update Notification messages are exchanged using a
   new Mobility Header message type specifically designed for this
   purpose.

1.  Introduction

   In some situations, there is a need for the local mobility anchor
   (LMA) to send asynchronous notification messages to the mobile access
   gateway (MAG) in the course of a mobility session.  These situations
   include changes to mobility session parameters and policy parameters.
