name: PCRF
full_form: Policy Charging and Rules Function
context: For PDP Contexts/EPS bearers used to carry IMS media flows, specific policies may be applied. The policy includes packet filtering, which enables a specific charging for these PDP Contexts/EPS bearers, see 3GPP TSÂ 29.212Â [75].
  The creation of a PDP Context/EPS bearer to be used to carry media flows involves interaction between the MS/UE and the GGSN/P-GW and between the GGSN/P-GW and the PCRF. The interaction between the GGSN/P-GW and the PCRF, i.e. the Gx interface, is described in detail in 3GPP TSÂ 29.212Â [75]. The interaction between the MS/UE and GGSN/P-GW is described in 3GPP TSÂ 29.213Â [76].
  If Gx is enabled for the APN, the GGSN/P-GW contacts the PCRF selected during the establishment of the APN.
description: The PCRF (Policy Charging and Rules Function) is a network function responsible for policy control, charging rules, and QoS management in the network. It interacts with other network functions like GGSN/P-GW to enforce policies.
explanation: PCRF is categorized as a Network Function because it plays a critical role in policy enforcement, charging, and QoS management through interaction with other network elements.
