    Abstract: According to an aspect of the present invention, a User equipment (UE) includes a controller and a transmission and/or reception circuitry, in which the transmission and/or reception circuitry receives, from an Access and Mobility Management Function (AMF), first information indicating whether or not a network supports Access Traffic Steering, Switching, Splitting (ATSSS), the controller determines whether or not ATSSS is supported by the network based on the first information, and the controller does not initiate a Protocol Data Unit (PDU) session establishment procedure for establishing a Multi-Access (MA) PDU session in a case that the network does not support ATSSS.

    Abstract: By introducing a concept such as an equivalent SNPN, mobility can be improved, service continuity can be improved, NSSAI can be appropriately managed, and an equivalent SNPN list can be appropriately managed. In a case that roaming is not performed and a UE receives a new allowed NSSAI for a current SNPN, the UE deletes one or more S-NSSAIs included in a new allowed NSSAI for the current SNPN and/or its equivalent SNPN from a pending NSSAI stored in the UE.

    Abstract: By introducing a concept such as an equivalent SNPN, mobility can be improved, service continuity can be improved, NSSAI can be appropriately managed, and an equivalent SNPN list can be appropriately managed. In a case of receiving a registration accept message including an NSSAI inclusion mode via a current access in a current SNPN in a current registration area, a UE also applies the NSSAI inclusion mode to an equivalent SNPN for the current SNPN in the current registration area.

    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 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.

    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.

    Abstract: A radio communication system includes a base station device and a plurality of mobile station devices which radio-communicate with the base station device. The base station device allocates random access signal identifiers for identifying random access signals to the mobile station devices and decides an allocation period for each of the random access signal identifiers used by the mobile base stations. During the allocation period, each of the mobile station devices transmits a random access signal corresponding to the allocated random access signal identifier. Thus, it is possible to suppress a delay until the random access procedure using a dedicated preamble is complete.
