Section: 5.33 Support for Ultra Reliable Low Latency Communication 5.33.1 General
Content: The following features described in 5.33 may be used to enhance 5GS to support Ultra Reliable Low Latency Communication (URLLC): - Redundant transmission for high reliability communication. In this Release, URLLC applies to 3GPP access only. When a PDU Session is to serve URLLC QoS Flow, the UE and SMF should establish the PDU Session as always-on PDU Session as described in clause 5.6.13. NOTE 1: How the UE knows whether a PDU Session is to serve a URLLC QoS Flow when triggering PDU Session establishment is up to UE implementation. NOTE 2: No additional functionality is specified for URLLC in order to support Home Routed roaming scenario in this Release.
