Feature Description

Gating control is the capability to block or allow IP packets belonging to a certain IP flow, based on the decisions by the PCF. The PCF could, for example, make gating decisions based on session events (start and stop of service) reported by the AF.

The AF instructs the PCF to temporarily block the user traffic corresponding to a specific PCC rule on uplink or downlink direction, or both the directions.

To enable the PCF gating control decisions, the AF reports session events (for example, session termination, modification) to the PCF. For example, session termination, in gating control, triggers the blocking of packets or "closing the gate".

Note

Gating Control applies only for service data flows of IP type.
