Systems and methods for closed loop QoS management

A system comprising:

• a first network device in a core network, the first network device configured to:
• receive, from an application function (AF) in a data network, a quality of service (QoS) monitoring request for a QoS flow supporting a protocol data unit (PDU) session, wherein the QoS monitoring request authorizes closed loop QoS management;
• and
• a policy control function (PCF) device in the core network, the second network device configured to:
• receive a QoS monitoring report based on QoS monitoring by an access station, wherein the QoS monitoring report includes data for one or more parameters for network services in a default QoS flow supporting the PDU session;
• determine, based on the QoS monitoring report, if the default QoS flow supports a required service level for the PDU session;
• and
• automatically activate, based on the QoS monitoring request, a dedicated QoS flow with a unique identifier to support the PDU session with the required service level, when it is determined that the default network slice does not support a required service level for the PDU session, wherein activating the dedicated QoS flow with the unique identifier includes creating a unique 5G QoS Identifier (5QI) for the dedicated QoS flow.

A non-transitory computer-readable medium containing instructions, executable by at least one processor, for:

• receiving, by a core network and from an application function (AF) in a data network, a quality of service (QoS) monitoring request for a QoS flow supporting a protocol data unit (PDU) session, wherein the QoS monitoring request authorizes closed loop QoS management;
• receiving, by a policy control function (PCF) device in the core network, a QoS monitoring report based on QoS monitoring by an access station, wherein the QoS monitoring report includes data for one or more parameters for network services in a default QoS flow supporting the PDU session;
• determining, by the PCF device and based on the QoS monitoring report, if the default QoS flow supports a required service level for the PDU session;
• and
• automatically activating, by the PCF device and based on the QoS monitoring request, a dedicated QoS flow with a unique identifier to support the PDU session with the required service level, when it is determined that the default QoS flow does not support a required service level for the PDU session,
• wherein activating the dedicated QoS flow with the unique identifier includes creating a unique 5G QoS Identifier (5QI) for the dedicated QoS flow.
