Classification: CPC H | IPC H

Claim 6:
7. A communications system, comprising:
a session management apparatus and a user plane apparatus;
the session management apparatus comprises:
at least one first processor; and
at least one first memory coupled to the at least one first processor and storing first programming instructions for execution by the at least one first processor, the first 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 the user plane apparatus and a terminal, wherein the service path is a QoS flow identified by a QoS flow identifier; and
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;

user plane apparatus comprises:
at least one second processor; and
at least one second memory coupled to the at least one second processor and storing second programming instructions for execution by the at least one second processor, the second programming instructions instruct the user plane apparatus to:
perform the per QoS flow QoS monitoring based on the request;
receive the request; and
send 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 monitored delay of the QoS flow and the QoS flow identifier.
