Abstract: A user plane function receives, from a session management function, a request for at least one quality of service (QoS) report for a data flow, the request indicating: a QoS event; and a first QoS value for the QoS event. Monitoring packets for monitoring a second QoS value of the data flow are sent to a base station. A determination is made of an occurrence of the QoS event based on the second QoS value and the first QoS value. An indication of the occurrence is sent to the session management function.

Abstract: A method by a user plane function (UPF) is provided. The method includes receiving, from a session management function (SMF), a first message to request at least one quality of service (QoS) monitoring for a data flow, the first message including information on a packet transmission delay and information on a first QoS value related to a threshold for the packet transmission delay, sending, to a base station, a monitoring packet, determining a second QoS value corresponding to a delay between the UPF and the base station, identifying whether a QoS event is triggered based on the first QoS value and the second QoS value, and sending, to the SMF, a second message in case that the QoS event is triggered.
