1. A method comprising:
receiving, by an access network (AN) node from a session management function (SMF), a request for monitoring Quality of Service (QoS) event associated with a packet delay;
receiving, by the AN node, an uplink protocol data unit (PDU) associated with a PDU session; and
sending, by the AN node to a user plane function (UPF) over more than one user plane (UP) path, a PDU including the uplink PDU, wherein the PDU further includes a timestamp indicating at which time point the PDU leaves the AN node;
wherein the packet delay is a duration between the time point indicated by the timestamp and a time point at which the PDU arrives at the UPF, and
monitoring the packet delay over each of the user plane (UP) paths and reporting the packet delay over each of the UP paths to the SMF.
