Abstract
A method of maintaining SIP registration in a SIP network for a SIP User Agent resident on a client device, the SIP User Agent having registered with a Push Provider to receive Push Notifications via an Operating System of the client device. The method comprises notifying a push gateway, present in a SIP path between the SIP User Agent and the SIP network, that the SIP User Agent is registered with the Push Provider, the push gateway having an interface to a push server of the Push Provider. The method further comprises performing initial SIP registration of the SIP User Agent with the SIP network via a SIP connection extending through the push gateway and thereafter maintaining a re-registration timer at the push gateway and, upon or prior to expiry of the timer, sending a push notification identifying a re-registration event from the push gateway to the client device via the push server. The push notification is received at the client device which passes the event notification to the SIP User Agent. Re-registration of the SIP User Agent is then performed with the SIP network via a SIP connection extending through the push gateway.
