Abstract: A UE capable of performing communication via a satellite receives a wait range via a first satellite from a first PLMN. In a case that the UE becomes able to perform communication via a second satellite connected to the first PLMN after becoming unable to perform communication via the first satellite, the UE selects the first PLMN, generates a wait timer based on the wait range, and starts a timer using the wait timer. In a case that an emergency call is made during the timer running, the UE stops the timer and performs a registration procedure for the emergency call. In a case that an emergency call is not made during the timer running, the UE performs the registration procedure after the timer expires.
