User equipment (UE) including first single network slice selection assistance information (S-NSSAI), second S-NSSAI, first protocol data unit (PDU) session of session and service continuity (SSC) mode 2, and second PDU session

A User Equipment (UE) comprising:

• transmission and reception circuitry;
• and
• controlling circuitry,
• wherein
• the transmission and reception circuitry is configured to receive, from a network, a Protocol Data Unit (PDU) session release command message including a second Single Network Slice Selection Assistance Information (S-NSSAI),
• the controlling circuitry is configured to release a first PDU session,
• the first PDU session is a PDU session of a Session and Service Continuity (SSC) mode 2,
• an S-NSSAI of the first PDU session is a first S-NSSAI different from the second S-NSSAI,
• the transmission and reception circuitry is configured to transmit, to the network, the second S-NSSAI and a PDU session establishment request message, and
• the controlling circuitry is configured to establish a second PDU session.
