Title:
USER DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/105547
Kind Code:
A1
Abstract:
Provided is a communications means for achieving functions for URLLC requiring highly reliable and/or low latency communications in a 5G system. This user device provides a communications means capable of URLLC functions in a 5G system, as a result of: using a registration procedure to send registration request messages including information identifying other user devices and receiving registration acceptance messages including UE RG, DNN for URLLC, and S–NSSAI; and using a first PDU session establishment procedure to send PDU session establishment request messages including information that indicates that the SSC mode for a PDU session for URLLC is SSC mode 1 and establish the PDU session on the basis of receiving a PDU session establishment acceptance message as a response to the PDU session establishment request message.
