"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:

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).
