Classification: CPC H | IPC H

Claim 0:
1. A method, comprising:
determining, by a session management apparatus, 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;
sending, by the session management apparatus, a request to the user plane apparatus, wherein the first link quality 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;
receiving, by the user plane apparatus, the request;
performing, by the user plane apparatus, the per QoS flow QoS monitoring based on the request
sending, by the user plane apparatus, a notification to the session management apparatus in response to that a monitored delay of the QoS flow is greater than or equal to the latency threshold, wherein the notification comprises the the QoS flow identifier and the monitored delay of the QoS flow; and
receiving, by the session management apparatus, the notification.
