Korhonen Broadcom November 2013 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. Status of This Memo This is an Internet Standards Track document.

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. In this context, "Asynchronous messages" is used to mean messages that are not synchronous with the Proxy Binding Update and Proxy Binding Acknowledgement messages of the base Proxy Mobile IPv6Show full document text
