Apparatus for supporting and influencing QoS levels

A method comprising:

• configuring, by an application function (AF) of in a mobile network system, a policy control function (PCF) to provide a plurality of Quality of Service (QoS) levels for a session related to an application or a service;
• sending, by the AF, a request signal to the PCF, wherein the request signal comprises a request to the PCF to associate each of a plurality of QoS flows having a QoS flow identifier (QFI) with a QoS profile for configuring the plurality of QoS levels, and the request signal comprises the plurality of QoS levels;
• and
• wherein the request signal instructs the PCF to switch from a current QoS profile of the plurality of QoS profiles to another QoS profile of the plurality of QoS profiles in response to a modification of one or more parameters of a PDU session.

An application function (AF) 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:
• causing the application function (AF) to configure a policy control function (PCF) to provide a plurality of Quality of Service (QoS) levels for a session related to an application or a service;
• causing the AF to send a request signal to the PCF, wherein the request signal comprises a request to the PCF to associate a QoS flow having a QoS flow identifier (QFI) with a plurality of QoS profiles for configuring the plurality of QoS levels, and the request signal comprises the plurality of QoS levels;
• and
• wherein the request signal instructs the PCF to switch from a current QoS profile of the plurality of QoS profiles to another QoS profile of the plurality of QoS profiles in response to a modification of one or more parameters of a PDU session.
