1. A User Equipment (UE) comprising:
transmitting and receiving circuitry configured to:
in a UE-requested Protocol Data Unit (PDU) session establishment procedure,
transmit a PDU session establishment request message to a control device in a core network; and
receive a PDU session establishment reject message including a 5GS Session
Management (5GSM) cause value from the control device; and
a controller,
wherein
the controller initiates the UE-requested PDU session establishment procedure with Local Area Data Network (LADN) Data Network Name (DNN) to establish a PDU session for LADN,
in a case that the 5GSM cause value indicates the UE is out of LADN service area, the controller configures the transmitting and receiving circuitry not to send a PDU session establishment request message with the LADN DNN until LADN information for the LADN DNN is updated.
