Abstract
A timer may be used by a device during registration for one or more services of a telecommunication service provider. The function of the timer is to decrease the time that the device (and, hence, the user of the device) waits for successful registration in instances where the device becomes aware that the user clearly wants to use a service (e.g., make a call). The timer may be configured to start in response to the device receiving user input to establish a communication session during registration, and to stop in response to the device receiving a response indicating a successful registration. If the timer expires during registration, an IMS restoration procedure may be performed to attempt registration using a different approach, which, because of the relatively short duration of the timer, expedites the IMS restoration procedure to establish the session more quickly.
