      Push Notification with the Session Initiation Protocol (SIP)
                     draft-ietf-sipcore-sip-push-20

Abstract

   This document describes how a Push Notification Service (PNS) can be
   used to wake suspended Session Initiation Protocol (SIP) User Agents
   (UAs), using push notifications, for the UA to be able to send
   binding refresh REGISTER requests and to receive receive incoming SIP
   requests.  The document defines new SIP URI parameters and new
   feature-capability indicators that can be used in SIP messages to
   indicate support of the mechanism defined in this document, to
   exchange PNS information between the SIP User Agent (UA) and the SIP
   entity that will request push notifications towards the UA, and to
   trigger such push notification requests.
