Claim 13:
14. A session management apparatus, comprising:
at least one processor, and
at least one memory coupled to the at least one processor and storing programming instructions for execution by the at least one processor, the programming instructions instruct the session management apparatus to:
determine a monitoring link to trigger per quality of service (QoS) flow QoS monitoring of a service path between a user plane apparatus and a terminal, wherein the service path is a QoS flow identified by a QoS flow identifier;
send a request to the user plane apparatus, wherein the request indicates the user plane apparatus to report QoS information of the QoS flow in response to one or more reporting conditions being satisfied, wherein the one or more reporting conditions comprise a condition that a latency parameter of the QoS flow is greater than or equal to a latency threshold, wherein the request comprises the QoS flow identifier indicating the QoS flow for the per QoS flow QoS monitoring and the latency threshold indicating a threshold for a downlink packet delay or an uplink packet delay; and
receive a notification message from the user plane apparatus, wherein the notification message comprises the QoS flow identifier and a monitored delay of the QoS flow that is greater than or equal to the latency threshold.
