32.2983GPPCharging Data Record (CDR) parameter descriptionCharging managementRelease 18Telecommunication managementTS

This clause specifies the parameters and the abstract syntax of the CDRs defined for 3GPP charging management in the set of domain TSs 32.25x (CS, PS, 5GS), subsystem TSs 32.26x (IMS) and service TSs 32.27x (MMS, LCS, PoC, MBMS, SMS, MMTel etc.). In doing this, the ASN.1 specified by X.680 [300] is utilized as the notational tool.

This clause is organised in two parts:

– the first part describes the CDR parameters;

– the second part specifies the abstract syntax of the CDRs as seen in the CDR files transferred across the Bx interface.

Each part is further subdivided into a number of clauses that contain generic, bearer level, service level, and subsystem level CDR parameters and abstract syntax definitions. The converged charging CHF-CDR is described under one clause encompassing NF specific parts. Word processing features, such as formatting options, have also been used to enhance human readability.

The complete set of all CDR syntax definitions is replicated in annex A in a machine processable format. Technically, the contents of this clause and annex A are completely identical. In case of deviations between this clause and annex A due to errors in the present document, the annex shall prevail.

Note that the encoding rules for the abstract syntax specified in this clause, are detailed in clause 6.
