Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 16:
17. A system, comprising:
a Policy Control Function (PCF); and
an Application Function (AF); wherein
the PCF comprises:
at least one first processor; and
one or more first memories coupled to the at least one first processor and storing first programming instructions for execution by the at least one first processor to cause the PCF to perform first operations comprising:
receiving, by the PCF from the AF, a request for configuring multiple Quality of Service (QoS) levels for a session related to an application, wherein a QoS flow for the application is associated with multiple QoS profiles for implementing the multiple QoS levels; and wherein a policy and charging control (PCC) rule is configured to support the multiple QoS levels and enables the multiple QoS profiles for the QoS flow, and wherein a QoS level is downgraded when a target QoS level cannot be fulfilled for the session;

the AF comprises:
at least one second processor; and
one or more second memories coupled to the at least one second processor and storing second programming instructions for execution by the at least one second processor to cause the AF to perform second operations comprising:
sending, by the AF to the PCF, the request for configuring multiple QoS levels.
