"Bx" is a common designator for the reference points from the network to the Billing Domain (BD) that are intended for
the transport of CDR files.
The letter "x
" indicates the different 3GPP network domain, subsystem or service, thus:
represents Circuit Switched (CS)
in TS 32.250
represents Control Plane data transfer
in TS 32.253
represents IP Multimedia Subsystem (IMS)
in TS 32.260
represents Location Service (LCS)
in TS 32.271
represents Multimedia Messaging Service (MMS)
in TS 32.270
represents Multimedia Broadcast/Multicast Service (MBMS)
in TS 32.273
represents Monitoring Event
in TS 32.278
represents Online Charging System (OCS)
in TS 32.296
represents Packet Switched (PS)
in TS 32.251
represents Proximity-based Services (ProSe)
in TS 32.277
represents CAMEL SCF
in TS 23.078
represents Short Message Service (SMS)
in TS 32.274
represents Push-to-talk over Cellular service (PoC)
in TS 32.272
represents Wireless LAN (WLAN)
in TS 32.252
The present document is part of a series of documents that specify charging functionality and charging management in 3GPP networks/systems. The 3GPP core network charging architecture and principles are specified in the present document, which thus provides an umbrella for other charging management TSs that specify:
the content of the CDRs per domain / subsystem /service (offline charging);
the content of real-time charging events per domain / subsystem /service (online charging);
the functionality of online and offline charging for those domains / subsystems / services;
the interfaces that are used in the charging framework to transfer the charging information (i.e. CDRs or charging events).
The purposes of the present document are:
to lay down common principles of charging in the network; and
to specify a logical common charging architecture that applies to all 3GPP domains, subsystems and services.
A set of domain/subsystem/service specific TSs covers the domains (CS, PS, 5GS), subsystem (IMS) and service (MMS, LCS, PoC, MBMS, SMS, MMTel etc.) levels, respectively, in the TS 32.25x
, TS 32.26x
and TS 32.27x
TS number ranges. These TSs describe the mapping of the common architecture specified in the present document onto the specific domain/subsystem/service and the scenarios and information for online and offline charging that are specific to the domain/subsystem/service. They are commonly referred to as the middle tier charging TSs.
A set of TSs in the TS 32.28x
range covers common services, such as the Advice of Charge service.
A set of TSs in the TS 32.29x
range covers common aspects, such as CDR parameter and syntax descriptions, online and offline charging applications, and the charging interactions within the network (CDR transfer) as well as between the network and the Billing Domain (CDR file transfer).
