Push Notification with the Session Initiation Protocol (SIP)
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 it 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. It also defines the parameters to
trigger such push notification requests. The document also defines
new feature-capability indicators that can be used to indicate
support of this mechanism.
