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.

Krishnan, et al. Standards Track [Page 2]RFC 7077 Update Notifications November 20131. 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.
