Abstract: Provided is a communication measure for registering information about a terminal apparatus in various apparatuses, such as a control apparatus and a terminal apparatus, included in a communication system in which a protocol used for registration management or registration information management for a mobile communication service is shared, based on the states of the various apparatuses. Also provided is a communication control measure for updating the information about the terminal apparatus registered in the various apparatuses. Thus, there are provided, in a communication system in which a protocol used for registration management or registration information management for a mobile communication service is shared, a measure for registration management based on the states of various apparatuses included in the communication system, such as a control apparatus and a terminal apparatus, and a realization measure for determining post-registration behavior.

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.

Abstract: A communication measure is provided that causes a PDU session established in a 5GS to return to an original state of the PDU session in a case that the PDU session is moved (handed over) to an EPS and then moved (handed over) to the 5GS again. In addition, according to the present invention, a communication measure is provided that causes a PDN connection established in the EPS to return to the PDN connection in an original state after the PDN connection established in the EPS is moved (handed over) to the 5GS and then again moved (handed over) to the EP. In addition, according to the present invention, a communication measure is provided that allows smooth mobility of the UE in an idle mode between the 5GS and the EPS. This allows a communication measure that performs a handover between the 5GS and the EPS smoothly to be provided.
