Abstract: In 5GS, provided is a communication unit for continuing services of a PDU session in a network slice in a case that the network slice is congested, a case that network performance of the network slice does not satisfy an SLA, or the like. In 5GS, provided are a method and a communication unit for a PDU session modification procedure, and/or a PDU session release procedure, and/or a PDU session establishment procedure, and/or a PDU session anchor change procedure, for implementing session and/or service continuity by changing a slice and changing PDU session anchor, in a case that a network slice is congested, a case that network performance of the network slice does not satisfy an SLA, or the like.

Abstract: A User Equipment (UE; terminal apparatus) includes a transmission and/or reception unit and a storage unit. The transmission and/or reception unit receives a first allowed Network Slice Selection Assistance Information (NSSAI) from a core network, and in a case that a registration area stored in the UE includes multiple pieces of tracking area information, the multiple pieces of tracking area information belong to different Public land mobile networks (PLMNs), and further the different PLMNs are Equivalent HPLMNs (EPLMNs), the storage unit stores the first allowed NSSAI received, in each allowed NSSAI associated with a corresponding one of the PLMNs.

Abstract: Provided are procedures for initial UE registration and periodic or movement-based registration, and a communication unit to achieve management of the maximum number of UEs connected to each slice in 5GS. Furthermore, a method for managing a timer running after completion of the registration procedure, and a method of registration procedure and a communication unit for both a UE in which the timer is running and a UE in which the timer is not running are provided, thus providing a communication unit to implement functions related to the management of the maximum number of UEs connected to each slice in 5GS.

Abstract: A User Equipment (UE) includes a transmission and reception unit, a storage unit, and a controller, in which the transmission and reception unit is configured to receive Allowed Network Slice Selection Assistance Information (NSSAI) and one or more first mapped Single Network Slice Selection Assistance Information (S-NSSAI) for the Allowed NSSAI, and unless the storage unit stores an S-NSSAI associated with second mapped S-NSSAI in rejected NSSAI and the second mapped S-NSSAI is not included in the one or more first mapped S-NSSAI for the Allowed NSSAI, the controller removes an S-NSSAI included in the Allowed NSSAI from the rejected NSSAI stored in the storage unit.

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 transmission and reception unit, a controller, and a storage unit. The transmission and reception unit receives allowed Network Slice Selection Assistance Information (NSSAI). In a case that the UE is roaming, the controller deletes mapped Single Network Slice Selection Assistance Information (S-NSSAI) of the allowed NSSAI from pending NSSAI stored by the storage unit.
