Plain-language definition
The policy decision point for data sessions.
Technical definition
The PCRF provides QoS and charging rules over Gx and Rx and coordinates roaming policy over S9. Guardivia provides the interfaces and DRA, not the PCRF.
Why it matters
Policy control shapes data services; the DRA routes to it.
