17 16 TS V ( ) 1 Scope The present document provides the stage 3 specification of the Gx, Gxx and Sd reference points for the present release. The present document also provides the Diameter variant of St reference point for the present release. The functional requirements and the stage 2 specifications of the Gx, Gxx, Sd and St reference points are contained in 3GPP TS [7]. The Gx reference point lies between the Policy and Charging Rule Function and the Policy and Charging Enforcement Function. The Gxx reference point lies between the Policy and Charging Rule Function and the Bearer Binding and Event Reporting Function. The Sd reference point lies between the Policy and Charging Rule Function and the Traffic Detection Function. The St reference point lies between the Policy and Charging Rule Function and the Traffic Steering Support Function. Whenever it is possible the present document specifies the requirements for the protocol by reference to specifications produced by the IETF within the scope of Diameter. Where this is not possible, extensions to Diameter are defined within the present document. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - References are either specific (identified by date of publication and/or edition number or version number) or non-specific. - For a specific reference, subsequent revisions do not apply. - For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.

The logic is entirely internal to a TDF or a PCEF enhanced with ADC, and is out of scope of this specification. Application identifier: An identifier, referring to a specific application detection filter. ADC decision: A decision consists of references to ADC rules, associated enforcement actions (for dynamic ADC rules) and TDF session attributes and is provided by the PCRF to the TDF for application detection and control.

20 19 TS V ( ) ADC rule: A set of information enabling the detection of application traffic and associated enforcement actions. ADC rules are directly provisioned into the TDF and referenced by the PCRF. Detected application traffic: An aggregate set of packet flows that are generated by a given application and detected by an application detection filter. IP-CAN bearer: IP transmission path of defined capacity, delay and bit error rate, etc. See 3GPP TR [1] for the definition of bearer. IP-CAN session: association between a UE and an IP network. The association is identified by one or more UE Ipv4 addresses/ and/or Ipv6 prefix together with a UE identity information, if available, and a PDN represented by a PDN ID (e.g. an APN). An IP-CAN session incorporates one or more IP-CAN bearers. Support for multiple IP-CAN bearers per IP-CAN session is IP-CAN specific. An IP-CAN session exists as long as the related UE Ipv4 address and/or Ipv6 prefix are assigned and announced to the IP network. IP flow: unidirectional flow of IP packets with the same source IP address and port number and the same destination IP address and port number and the same transport protocol. Port numbers are only applicable if used by the transport protocol. IP Flow mapping: IP flow mapping is used in Network-initiated NBIFOM mode when the UE wants to request the network to apply specific mapping of IP flows to 3GPP access or WLAN access. It applies to the same parameters as the NBIFOM routing rule. Gateway Control Session: An association between a BBERF and a PCRF (when GTP is not used in the EPC), used for transferring access specific parameters, BBERF events and QoS rules between the PCRF and BBERF. In the context of this specification this is implemented by use of the Gxx procedures. GC1 signalling: Signalling between the GCS AS and the application client on the UE over the GC1 reference point as defined in 3GPP TS [50]. Monitoring key: Identifies a usage monitoring control instance. Multi-access IP-CAN session: An IP-CAN session whose traffic can be routed over either a 3GPP access or a WLAN access or both. Each IP flow is routed at any single time only over one access. TDF session: An association between an IP-CAN session and the assigned TDF for the purpose of application detection and control by the PCRF. The association is identified by one UE Ipv4 address and/or Ipv6 prefix together with optionally a PDN represented by a PDN ID and a set of ADC rules to be applied by the TDF. Usage monitoring control instance: the monitoring and reporting of the usage threshold for input, output or total data volume or time of usage for the IP-CAN session/tdf session or the service data flows/application's traffic associated with the same monitoring key. Presence Reporting Area: An area defined within 3GPP Packet Domain for the purposes of reporting of UE presence within that area due to policy control and/or charging reasons. There are two types of Presence Reporting Area: "UEdedicated Presence Reporting Area", and "Core Network pre-configured Presence Reporting Area". Packet Flow Description (PFD): A set of information enabling the detection of application traffic provided by a 3 rd party service provider (from 3GPP TS [7]). RAN rules: In this specification, RAN rules refers to the set of RAN assistance parameter and RAN steering command handling for the steering of traffic between E-UTRAN or UTRAN and WLAN associated with RAN-controlled LTE- WLAN interworking or RAN-assisted WLAN interworking. RAN user plane congestion: RAN user plane congestion occurs when the demand for RAN resources exceeds the available RAN capacity to deliver the user data for a prolonged period of time. Service data flow: An aggregate set of packet flows carried through the PCEF that matches a service data flow template (from 3GPP TS [7]). Service data flow filter: a set of packet flow header parameter values/ranges used to identify one or more of the packet flows (from 3GPP TS [7]). Service data flow template: The set of service data flow filters in a PCC rule or an application identifier in a PCC rule referring to an application detection filter, required for defining a service data flow (from 3GPP TS [7]).

21 20 TS V ( ) (S)Gi-LAN: The network infrastructure connected to the 3GPP network over the SGi or Gi reference point that provides various IP-based services. (S)Gi-LAN service function: A function located in the (S)Gi-LAN that provides value-added IP-based services e.g. NAT, anti-malware, parental control, DDoS protection. 3.2 Abbreviations For the purpose of the present document, the abbreviations given in 3GPP TR [1] and the following apply: ADC Application Detection and Control AF Application Function AMBR Aggregate Maximum Bit Rate BBERF Bearer Binding and Event Reporting Function CCA Credit-Control-Answer (CC-Answer) CCR Credit-Control-Request (CC-Request) CSG Closed Subscriber Group CSG-ID Closed Subscriber Group Identity DCC Diameter Credit Control DRMP Diameter Routing Message Priority GBR Guaranteed Bit Rate GCS Group Communication Service GCS AS Group Communication Service Application Server MPS Multimedia Priority Service NBIFOM Network-based IP flow mobility NB-IoT Narrowband IoT OCS Online charging system OFCS Offline charging system PCEF Policy and Charging Enforcement Function PCRF Policy and Charging Rule Function PFD Packet Flow Description PFDF Packet Flow Description Function PRA Presence Reporting Area RAA Re-Auth-Answer (RA-Answer) RAB Radio Access Bearer RAR Re-Auth-Request (RA-Request) RCAF RAN Congestion Awareness Function RUCI RAN User Plane Congestion Information SCEF Service Capability Exposure Function SUPL Secure User Plane for Location TDF Traffic Detection Function TSA TDF-Session-Answer TSR TDF-Session-Request TSSF Traffic Steering Support Function UDC User Data Convergence UDR User Data Repository WB-E-UTRAN Wide Band E-UTRAN 4 Gx reference point 4.1 Overview The Gx reference point is located between the Policy and Charging Rules Function (PCRF) and the Policy and Charging Enforcement Function (PCEF). The Gx reference point is used for provisioning and removal of PCC rules from the PCRF to the PCEF and the transmission of traffic plane events from the PCEF to the PCRF. The Gx reference point can be used for charging control, policy control or both by applying AVPs relevant to the application. The Gx reference point can also be used for application's traffic detection and control. The stage 2 level requirements for the Gx reference point are defined in 3GPP TS [7].

22 21 TS V ( ) Signalling flows related to the both Rx and Gx interfaces are specified in 3GPP TS [8]. The definition of case 1, case 2a and case 2b is specified in clause 4.0 in 3GPP TS [8]. Refer to Annex G of 3GPP TS [8] for Diameter overload control procedures over the Gx interface. Refer to Annex J of 3GPP TS [8] for Diameter message priority mechanism procedures over the Gx interface. Refer to Annex K of 3GPP TS [8] for Diameter load control procedures over the Gx interface. The PCEF is considered as monolithic entity in the present specification, but can be decomposed into a User Plane Function and a Control Plane Function connected via the Sx reference point. The Sx reference point and interactions between the Gx and Sx reference points are not considered in the present specification, but are specified in 3GPP TS [63]. 4.2 Gx Reference model The Gx reference point is defined between the PCRF and the PCEF. The relationships between the different functional entities involved are depicted in figure The overall PCC architecture is depicted in subclause 3a of 3GPP TS [8]. Gx PCEF PCRF Figure 4.2.1: Gx reference model NOTE 1: The PCEF may support Application Detection and Control feature. NOTE 2: PCEF is located in the Gateway node implementing the IP access to the PDN. Refer to Annexes of TS [7] for application to specific IP-CAN types. NOTE 3: The PCEF can be decomposed into a User Plane Function and a Control Plane Function connected via the Sx reference point specified in 3GPP TS [63]. If the PCEF is decomposed, the Gx reference point terminates in the Control Plane Function. Figure 4.2.2: Void 4.3 PCC Rules PCC Rule Definition The purpose of the PCC rule is to: - Detect a packet belonging to a service data flow. - The service data flow templates within the PCC rule are used for the selection of downlink IP CAN bearers. - The service data flow filters within the PCC rule are used for the enforcement that uplink IP flows are transported in the correct IP CAN bearer. NOTE 1: For apcc rule that contains an application identifier referencing an application detection filter, the PCRF can inspect traffic on multiple bearers in the uplink direction. Such detected traffic counts as detection by that PCC rule. - Identify the service the service data flow contributes to. - Provide applicable charging parameters for a service data flow.
