      Push Notification with the Session Initiation Protocol (SIP)
                     draft-ietf-sipcore-sip-push-28

Abstract

   This document describes how a Push Notification Service (PNS) can be
   used to wake a suspended Session Initiation Protocol (SIP) User Agent
   (UA) with push notifications, and also describes how the UA can send
   binding-refresh REGISTER requests and receive incoming SIP requests
   in an environment in which the UA may be suspended.  The document
   defines new SIP URI parameters to exchange PNS information between
   the UA and the SIP entity that will then request that push
   notifications be sent to the UA, and to trigger such push
   notification requests.  The document also defines new feature-
   capability indicators that can be used to indicate support of this
   mechanism.
