This interface provides transfer of policy and charging rules from PCRF to Policy and Charging Enforcement Function Point (PCEF) in the GW (e.g. GGSN, PDN GW). This interface is specified in TS 29.212.

This interface allows for dynamic QoS and charging-related service information to be exchanged between the Policy and Charging Rules Function (PCRF) and the Application Function (AF). This information is used by the PCRF for the control of service data flows and IP bearer resources. For more information see TS 23.203.

This interface allows for the PCRF to request subscription information from the SPR and the SPR to notify the PCRF when the subscription information has changed if the PCRF has requested such notifications. The details associated with the Sp reference point are not specified in this Release.

This interface allows for the online charging based on the Diameter credit control application between the Online Charging System (OCS) and the PCEF. For more information see TS 32.251 and RFC 4006 [102].

This interface allows for the offline charging based on the charging record data transfer between the Offline Charging System (OFCS) and the PCEF. For more information see TS 32.295.

This interface provides transfer of (QoS) policy information from PCRF to the Trusted Non-3GPP accesses. This interface is specified in TS 29.212..

This interface is not specified within this release of the specification.

The reference point transports access information from ePDG to PCRF/vPCRF for WLAN UEs such as the UE local IP address and the UDP port number. This interface is specified in TS 29.212. Gxb* is only applicable to the interworking with Fixed Broadband Access network.

This interface provides transfer of (QoS) policy information from PCRF to the Serving Gateway, Gxc is used only in the case of PMIP-based S5/S8. This interface is specified in TS 29.212..

This interface allows for a PCRF to have a dynamic control over the Bearer Binding and Event Report Function (BBERF) behaviour. For more information see TS 23.402 and TS 23.203. This interface is specified in TS 29.213

This interface provides transfer of policy and charging rules (in case of local breakout of traffic) and/or (QoS) policy information (when Gxx interface applies) between the Home PCRF and the Visited PCRF in order to support PCC roaming related functions. This interface is specified in TS 29.215.

This interface allows for the PCRF, acting as an UDC Application Frontend as defined in TS 23.335, to request subscription information from the UDR and the UDR to notify the PCRF when the subscription information has changed if the PCRF has requested such notifications. For details regarding the Ud reference point see TS 23.335 and TS 29.335.

The Sd Reference Point enables a PCRF to have dynamic control over the application detection and control behaviour at a TDF. The Sd Reference Point is specified in TS 29.212.

The Sy Reference Point enables transfer of information relating to subscriber spending from OCS to PCRF. The Sy Reference Point is specified in TS 29.219.

This reference point supports the initiation, modification and termination of sessions between the HNB GW and PCRF to support CS sessions. It triggers the PCRF to request allocation of resources in the Fixed Broadband access network for HNB CS calls. This interface is specified in TS 29.212. S15 is only applicable to the interworking with Fixed Broadband Access network.

This interface supports the transfer of (QoS) policy information from PCRF to BPCF of broadband access network. This interface is specified in TS 29.215. S9a is only applicable to the interworking with Fixed Broadband Access network.

The Gyn Reference Point allows for the online charging based on the Diameter credit control application between the Online Charging System (OCS) and the TDF. For more information see TS 32.251 and RFC 4006 [102].

The Gzn Reference Point allows for the offline charging based on the charging record data transfer between the Offline Charging System (OFCS) and the TDF. For more information see TS 32.295.

The St Reference Point enables a PCRF to have dynamic control over the traffic steering behaviour at a TSSF. The St Reference Point is specified in TS 29.212.

The Gw reference point enables the PFDF to provide PFDs to the PCEF as described in TS 23.203.

The Gwn reference point enables the PFDF to provide PFDs to the TDF as described in TS 23.203.

This reference point is used to exchange signalling between IP-SM-GW and the HSS for SMSIP delivery. The details for this reference point are described in TS 23.204.

This reference point is used to exchange user between Application Front Ends and the UDR. The details for this reference point are described in TS 23.335 and TS 29.335.
