The present document is part of a series of Technical Specifications (TSs) that specify charging functionality and charging management in 3GPP networks (GSM/UMTS/EPS). The 3GPP core network charging architecture and principles are specified in document TS 32.240 [1], which provides an umbrella for other charging management documents that specify:

- the content of the CDRs per domain and subsystem (offline charging);

- the content of real-time charging events per domain/subsystem (online charging);

- the functionality of online and offline charging for those domains and subsystems;

- the interfaces that are used in the charging framework to transfer the charging information (i.e. CDRs or charging events).

The complete document structure for these TSs is defined in TS 32.240 [1].

The present document specifies the CDR parameters, the abstract syntax and encoding rules for all the CDR types that are defined in the charging management TSs described above. Therefore, it is only applicable to offline charging. The mechanisms used to transfer the CDRs from the generating node to the operator's Billing Domain (e.g. the billing system or a mediation device) are specified in TS 32.297 [52]. Further details with respect to the operator's Billing Domain for offline charging are out of scope of 3GPP standardisation.

Note that a generic Diameter application for online charging in 3GPP networks is specified in TS 32.299 [50]. Furthermore, 3GPP TSs are being created to standardise some technical aspects of the operator's Billing Domain for online charging, i.e. the Online Charging System (OCS).
