1. A Policy Control Function (PCF), in a mobile network system, comprising:
at least one processor; and
one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor, wherein the programming instructions instruct the at least one processor to perform operations comprising:
receiving by the PCF, from an Application Function (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, wherein the PCC rule enables the multiple QoS profiles for the QoS flow, and a QoS level is downgraded when a target QoS level cannot be fulfilled for the session.
