MONITORING FOR APPLICATION AI/ML-BASED SERVICES AND OPERATIONS

A 5G or 6G communication system for supporting a higher data transmission rate. A method for monitoring events in a network comprises: subscribing, by an Application Function (AF), to monitoring the events, wherein the AF supports one or more AIML-based services and/or operations, and the events relate to the performance of the AIML-based services and/or operations; in response to the subscribing, monitoring, by a User Plane Function (UPF), the events; and when an event is detected, reporting, by the UPF to a Network Exposure Function (NEF), the event. The monitoring events may comprise one or more of: monitoring session inactivity of a PDU session; monitoring traffic volume of a PDU session; monitoring PCF events; per-5QI monitoring; and monitoring of edge resources. The monitoring may comprise QoS monitoring and may be performed for multiple UEs.
