Abstract: A system and method for recovering application authentication with an application server by using an exponential back-off procedure via push notifications is discussed herein. The system allows for authentication of a user account after network outages or service disruptions without traffic overload during recovery. A user equipment (UE) receives a failed registration notification after a failed registration attempt of the user account with an application server associated with the application. A push notification includes an instruction that causes the application to switch from an inactive state to a temporary active state. The push notification is sent from a push notification service in response to a push request from a notification server based on a recovery request from the UE due to the failed registration notification. While the application is in the temporary active state, the instruction further causes the application to request registration with the application server.

Abstract: Systems and methods for providing mobile network services are described herein. The systems and methods enable a user to register an endpoint for use on a mobile network. When registered on the mobile network, the endpoint can be used for mobile network services, such as placing or receiving audio/video calls.
