Feature Description

PCF supports the Flexible QoS Actions feature on the N7 interface. During policy management on the N7 interface, PCF sends session rules that are based on the configured QoS to the SMF.

The following QoS actions are applicable to an uplink AMBR and downlink AMBR are configurable for calculating the session rules. The default configuration is QoS-Enforcement.

  • QoS-Bounding facilitates PCF to calculate the minimum QoS between the Requested QoS (from the SMF) and the calculated QoS based on the internal logic, and authorize that in the response message to the SMF.

  • QoS-Mirroring is the ability for the PCF to grant or authorize the requests from the SMF.

  • QoS-Enforcement is the ability for the PCF to enforce the calculated QoS (computed based on PCF's internal logic) back to the SMF in the request or response message. This is the default configuration.
