Abstract
A User Equipment (UE) transmits a registration request message to an AMF in a registration procedure to a core network, the registration request message including information indicating a request for transmission of LADN information, receives the LADN information from the AMF, performs a PDU session establishment procedure initiated by the UE to establish a first PDU session with a DN different from the LADN, and performs the PDU session establishment procedure initiated by a network to establish a second PDU session with the LADN in a case that the UE moves to an area connectable to the LADN. This provides a control method that should be performed by each apparatus constituting a 5GS for the UE to establish the session to the LADN, and a control method for allowing only the UE connectable to the LADN to establish the session to the LADN.
