Summary: This draft is ready for publication as Proposed Standard

I had to read through this text several times to convince myself implementers could figure out what order they were required to take steps in vs where they had flexibility:
    o  Upon accepting the Update Notification message, the mobile access
       gateway MUST process the message and perform the actions based on
       the Notification Reason.
       *  If the (A) flag in the message is set to a value of (1), the
          mobile access gateway MUST first send an Update Notification
          Acknowledgement message and set the status code field according
          to the result of processing the Update Notification message.

In particular, it's not immediately obvious if there is tension between that "MUST first" and having "the result of processing" available. Please consider rewording to make it clearer that this "result of processing" is not intended to include waiting for the result of some action processing this notification message might trigger.

It might help readers understand the intended usual case retransmission mechanics if the expected default values listed in section 7 were called out earlier in the document.
