Abstract: A UE receives, from a first base station apparatus, system information and/or a registration accept message including a first frequency band supported by the first base station apparatus, first S-NSSAI corresponding to a first frequency band, a second frequency band supported by a second base station apparatus, and second S-NSSAI corresponding to a second frequency band. The UE recognizes that a registration request message and/or a PDU session establishment request message including the second S-NSSAI is not transmittable via the first base station apparatus, and in a case of reselecting a cell of the second base station apparatus, recognizes that the registration request message and/or the PDU session establishment request message including the first S-NSSAI is not transmittable via the second base station apparatus. This prevents, in a 5 GS, transmission of a registration request message and/or PDU session establishment request message which is unnecessary.
