This annex defines access specific procedures for use of Gxx between PCRF and a Non-3GPP access connected to EPC. Gx interface applies between the PCRF and the PCEF and shall follow the procedures within the main body of this specification.

If an EPC-based non-3GPP access (3GPP TS 23.402 [23]) requires Gxx for dynamic QoS control then it shall include the BBERF. The allocation of a BBERF to a node within the non-3GPP IP‑CAN is out of 3GPP scope, unless otherwise specified in this Annex.
