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.

RFC 7077 Update Notifications November 2013
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.
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 IPv6
