Abstract:
The Session Initiation Protocol (SIP) allows User Agents to register
for inbound requests. However, the existence of firewalls and
Network Address Translators (NATs) prevent servers from reaching the
User Agents unless the User Agents keep connections to the server
alive.
To keep such connections alive User Agents employ various methods,
most of which require constant uptime resulting in high energy cost.
This is especially a problem on mobile platforms that operate
entirely on battery power. To resolve these issues many mobile
manufacturers have provided a cost effective way of pushing messages
to their devices.
This specification defines behaviors for User Agents, registrars and
proxy servers that allow a User Agent to provide a Push Notification
Configuration to its Registrar.
