ETSI ETSI TS 129 210 V6.7.0 (2006-12) 6 3GPP TS 29.210 version 6.7.0 Release 6 1 Scope The present document provides the stage 3 specification of the Gx reference point. The fun
22、ctional requirements and the stage 2 specifications of the Gx reference point are contained in 3GPP TS 23.125 3. The Gx reference point is for provisioning service data flow based charging rules between the Traffic Plane Function (TPF) and the Charging Rules Function (CRF), also known as Service Dat
23、a Flow Based Charging Rules Function. The present document defines: - the protocol to be used between TPF and CRF over the Gx reference point; - the information to be exchanged between TPF and CRF over the Gx reference point. Whenever it is possible the present document specifies the requirements fo
24、r this 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. 3GPP TS 29.211 15 provides callflows for Flow Based Charging, covering the signalling on the Gx reference poin

37、erview The Gx reference point is used for provisioning service data flow based charging rules. The reference point is located between the Traffic Plane Function (TPF) and the Charging Rules Function (CRF), also known as Service Data Flow Based Charging Rules Function. The stage 2 level requirements
38、for the Gx reference point are defined in 3GPP TS 23.125 3. 4.2 Charging Rules Charging rules determine how service data flows are identified and charged. The TPF shall apply charging rules by evaluating received packets against service data flow filters. When a packet matches a service data flow fi
39、lter, the packet matching process for that packet is completed, and the charging rule for that filter shall be applied. Charging rules may be: - Pre-defined and active within the TPF, i.e. default rules that are configured within the TPF. - Pre-defined within the TPF but not active, i.e. charging ru
40、les that can be activated dynamically over the Gx reference point. - Pre-defined within the CRF and provided by the CRF, i.e. charging rules that can be installed dynamically over the Gx reference point. - Dynamically generated and provided by the CRF, i.e. charging rules that can be installed dynam
41、ically over the Gx reference point. (e.g. dynamic charging rules for example for IMS peer to peer service data flows, where both the service data flow filter and the charging rule are identified dynamically). NOTE: Whether the charging rule is pre-defined or dynamically generated by the CRF does not
42、 impact the procedures at the Gx reference point. - Pre-defined rules within the TPF may be grouped allowing CRF to dynamically activate a set of rules over the Gx reference point. A charging rule shall consist of a charging rule name, charging key (i.e. rating group), service identifier, service fl
43、ow filter and other charging parameters. The charging rule name shall be used to reference to a charging rule in the communication between the TPF and the CRF. The service identifier shall be used to identify the service or the service component the service data flow relates to. The service flow fil
44、ter shall be used to select the traffic for which the charging rule applies. The charging parameters define whether online and offline charging interfaces are used, what is to be metered in offline charging, what is the precedence of the charging rule, on what level the TPF shall report the usage re
45、lated to the charging rule, etc. For different charging rules with overlapping service data flow filter, the precedence of the charging rule determines which of these charging rules is applicable. Charging rule also includes Application Function record information for enabling charging correlation b
46、etween the application and bearer layer if the Application Function has provided this information via the Rx interface. For IMS this includes the IMS Charging Identifier (ICID) and flow identifiers. See the AVPs in clauses 5.2 and 5.3. 4.3 Functionality of the Gx reference point 4.3.1 Initialization
47、 and maintenance of connection The initialization and maintenance of the connection between each interworking CRF and TPF pair is defined by the underlying protocol. Establishment and maintenance of connections between Diameter nodes is described in IETF RFC 3588 4. ETSI ETSI TS 129 210 V6.7.0 (2006
48、-12) 9 3GPP TS 29.210 version 6.7.0 Release 6 4.3.2 Request for charging rules from the TPF The TPF shall indicate, via the Gx reference point, a request for charging rules in the following instances. 1) At bearer establishment: The TPF shall send a CC-Request with CC-Request-Type AVP set to the val
49、ue INITIAL_REQUEST. The TPF shall supply user identification and other attributes to allow the CRF to identify the charging rules to be applied. The other attributes shall include the type of the radio access technology (e.g UTRAN, GERAN, WLAN) and the UE IP address. For GPRS, information about the user equipment (e.g. IMEISV), QoS negotiated, SGSN Address, SGSN country and network codes, APN, TFT and indication if the bearer is used as IMS signalling PDP context shall be provided. 2) At bearer modification if an Event t
