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 registration procedure, a UE transmits a registration request message to start a timer T3510, and in a case that the UE receives a registration reject message without integrity protection including a 5GMM cause value indicating an illegal UE, the UE stops the timer T3510 in operation and deletes an equivalent SNPN list stored in the UE.

Abstract: In a UE configuration update procedure initiated by a network, when the UE is connected to the network via a satellite, one or more forbidden tracking area identities (TAIs) in a 5G system (5GS) forbidden tracking area information element for roaming and/or regional provision of service are included and transmitted in a configuration update command message transmitted by a 5G core network to the UE to provide an appropriate procedure for updating a tracking area identity (TAI) list stored in the UE while the UE in a 5GMM connected mode maintains a registered state.

Abstract: In a case that user equipment (UE) that has established a communication path for direct C2 communication receives, from a network, a PDU session release command message for revoking authentication and/or authorization of the communication path for the direct C2 communication or a PDU session modification command message, the UE can indicate an appropriate cause value in the procedure of releasing the communication path for the direct C2 communication.

Abstract: A unit is provided through an application of a disaster condition to a PLMN in 5GS, the unit being for transmitting and/or receiving a notification in a case that a communication service cannot be provided to a UE and for selecting a roaming destination PLMN by the UE. Provided are a procedure to allow the UE to recognize a state of a certain PLMN and transmit and/or receive information for appropriately selecting a PLMN as a moving destination in a case that a disaster condition applies or no longer applies to the certain PLMN, a method of selecting a PLMN based on information received and stored by the UE through a notification from the PLMN or the like, and a communication unit.

Abstract: A User Equipment (UE) includes a controller. In a case of connection to a Public Land Mobile Network (PLMN) service via a Stand-alone Non-Public Network (SNPN) by using 3GPP access, the controller does not operate in an SNPN access mode over non-3GPP access.

Abstract: A UE transmits a PDU session establishment request message including an S-NSSAI and a PDU session ID, and receives a PDU session establishment accept message including the S-NSSAI, the PDU session ID, a first cause value, a first back-off timer value, a first Session-AMBR IE, and a second Session-AMBR IE. The UE establishes a PDU session corresponding to the S-NSSAI, configures a back-off timer corresponding to the S-NSSAI to the first back-off timer value, and applies a data rate indicated by the second Session-AMBR IE to the PDU session while the back-off timer is running. In a case that the UE receives a PDU session modification command including the PDU session ID, a second cause value, a second back-off timer value, and a third Session-AMBR IE before expiration of the back-off timer, the UE, in a case that the second back-off timer value indicates other than 0, updates the back-off timer to the second back-off timer value, applies the data rate indicated by the third Session-AMBR IE to the PDU session, and updates, after expiration of the back-off timer, the data rate applied to the PDU session to the data rate indicated by the first Session-AMBR IE. This allows for provision of a communication unit for implementing a function related to management of a maximum number of UEs and/or a maximum number of PDU sessions connected for each network slice in a 5GS.

Abstract: According to one aspect of the present invention, a communication unit for realizing a function for ATSSS in a 5GS is provided. A UE transmits a PDU session establishment request message including an MA PDU Request indication and ATSSS Capability, and in a case that an MA PDU session is allowed to be established and that only the user plane resources for one of 3GPP access or non-3GPP access are allowed to be established, the UE receives information indicating that the MA PDU session is allowed to be established, an access type corresponding to the user plane resources allowed to be established, a value indicating a cause of disallowance of establishment of the user plane resource for an access type different from the above-described access type, and a PDU session establishment accept message including ATSSS rules, and establishes the MA PDU session.

Abstract: The present invention provides a communication method for realizing a function for URLLC that requires high-reliability and/or low-latency communication in a 5GS. A user apparatus can provide a communications method capable of realizing a URLLC function in a 5GS by performing the communication method, which comprises: receiving, in a registration procedure, a registration accept messages including DNN and S-NSSAI for URLLC; receiving, in a first PDU session establishment procedure, a PDU session establishment accept messages including information indicating that an SSC mode for a PDU session for URLLC is SSC mode 1; and transmitting, in a second PDU session establishment procedure, a PDU session establishment request messages including information indicating that the SSC mode for the PDU session for URLLC is SSC mode 1.
