The IMS network further comprises a call control system coupled to the subscriber server adapted to register user equipment of the subscriber assigned the new phone number with the subscriber server. The call control system is further adapted to associate an old phone number of the subscriber used prior to the split numbering plan area code with the new phone number in an implicit registration set. The call control system is further adapted to receive a call for the old phone number and identify the new phone number associated with the old phone number in the implicit registration set and to deliver the call to the user equipment.

Abstract: Flight check-in systems and associated methods are disclosed. A passenger is able to check in with an airline by initiating a call to a phone number designated for flight check-in. A flight check-in system receives the call initiated by the passenger and identifies a number (e.g., a phone number) based on the call. Based on the number, the flight check-in system identifies a flight reservation associated with the passenger. Subsequently, the flight check-in system generates a virtual boarding pass based on the flight reservation, and sends the virtual boarding pass to a gate at an airport for the passenger to board a flight.
