Title:
USER DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/207837
Kind Code:
A1
Abstract:
Provided is a user device that: in the process of registering with a core network, transmits a registration request message which includes information indicating a request for an AMF to transmit LADN information; receives LADN information from the AMF; executes a PDU session establishment procedure started by the user terminal, thereby establishing a first PDU session with a DN different from the LADN; and, if the user terminal has moved to an area allowing a connection to the LADN, executes a PDU session establishment procedure started by the network, thereby establishing a second PDU session with the LADN. Due to this configuration, the present invention provides a control method to be performed by each of devices constituting a 5GS, in order for a user device to establish a session with an LADN, and a control method for ensuring that only a user device which can connect to the LADN is able to establish a session with the LADN.
