1-20. (canceled)
A User Equipment (UE) comprising:
- transmission and reception circuitry configured for:
- in a Protocol Data Unit (PDU) session establishment procedure, receiving a PDU session establishment accept message including first information, from a first core network;
- and
- a controller configured for:
- establishing a PDU session based on the PDU session establishment procedure;
- and
- based on the reception of the first information, initiating a first procedure when changing a core network to be connected,
- wherein
- the first procedure is performed for the change of the core network to be connected.
A core network device comprising:
- transmission and reception circuitry configured for:
- in a Protocol Data Unit (PDU) session establishment procedure, transmitting a PDU session establishment accept message including first information, to a User Equipment (UE),
- wherein
