1. An apparatus for a session management function (SMF) in a 5th generation (5G) system, the apparatus comprising:
processing circuitry configured to:
determine whether quality of service (QoS) monitoring per QoS flow per user equipment (UE) for ultra-reliable low-latency communication (URLLC) service is enabled;
determine whether General Packet Radio Service (GPRS) Tunneling Protocol (GTP) user plane (GTP-U) path QoS monitoring is enabled;
when the QoS monitoring per QoS flow per UE for URLLC service is enabled:
send, to a packet data unit (PDU) session anchor (PSA) user plane function (UPF) and a next generation radio access network (NG-RAN), a request for the QoS monitoring per QoS flow per UE, the request for the QoS monitoring per QoS flow per UE comprising an indication that event-triggered QoS flow QoS monitoring is supported and at least one delay threshold to report packet delay for the QoS monitoring per QoS flow per UE; and
in response to the at least one delay threshold to report packet delay for the QoS monitoring per QoS flow per UE being reached, receive, from the PSA UPF, a report containing results from the QoS monitoring per QoS flow per UE; and
when the GTP-U path QoS monitoring is enabled:
send, to the PSA UPF and the NG-RAN, a request for the GTP-U path QoS monitoring, the request for the GTP-U path QoS monitoring comprising an indication that event-triggered GTP-U path QoS monitoring is supported and at least one delay threshold to report packet delay for the GTP-U path QoS monitoring;
in response to the at least one delay threshold to report packet delay for the GTP-U path QoS monitoring being reached, receive, from the PSA UPF, a report containing results from the GTP-U path QoS monitoring; and
determine, based on the report containing results from the GTP-U path QoS monitoring, QoS flow mapping to a network instance; and
a memory configured to store the report containing results from the GTP-U path QoS monitoring.
