Document Type and Number:
WIPO Patent Application WO/2020/105546
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. The user device provides a communications means capable of URLLC functions in a 5G system, as a result of: receiving, using a registration procedure, registration acceptance messages including DNN and S-NSSAI for URLLC; receiving, using a first PDU session establishment procedure, PDU session establishment acceptance messages including information indicating that the SSC mode for a PDU session for URLLC is SSC mode 1; and sending, using a second PDU session establishment procedure, PDU session establishment request messages including information indicating that the SSC mode for a PDU session for URLLC is SSC mode 1.
