6.1 Data description for MMTel offline charging

6.1.1 Rf message contents

6.1.1.0 Introduction

For offline charging, the different service CTFs supporting MMtel specific service charging generate accounting information transferred to the CDF using the Diameter accounting application, as described in TS 32.299 [50].

The Charging Data Request and Charging Data Response are used for this MMTel service offline charging, as described in TS 32.260 [20].

This clause describes the different fields used in the Charging Data messages and the category in the tables are used according to the charging data configuration defined in clause 5.4 of TS 32.240 [1].

6.1.1.1 Charging Data Request message description

The generic Charging Data Request message described in TS 32.260 [20] used for MMTel offline charging is enhanced with specific MMTel service information.

Table 6.1.1.1.1 illustrates the overall Charging Data Request message as used for MMTel offline charging.

Not applicable. Refer to sclause 5.2.3 for further information.

6.1.3 CDR description on the Bi interface

6.1.3.1 CDR field type

The MMTel CDR content and format description is based on TS 32.260 [20] AS-CDR description, enhanced with specific MMTel service information.

The content of MMTel CDR type is defined in the table in clause 6.1.3.3. The field definition includes the field name, category and description. The category in the tables are used according to the charging data configuration defined in clause 5.4 of TS 32.240 [1]. The detailed field descriptions are provided in TS 32.298 [51].

The CDF provides the CDRs at the Bi interface in the format and encoding described in TS 32.298 [51]. Additional CDR formats and contents may be available at the interface to the billing system to meet the requirements of the billing system, these are outside of the scope of standardization.

6.1.3.2 CDR triggers

Accounting information for MMTel services charging is transferred from the CTFs supporting MMtel service charging to the CDF, using Charging Data Request start, interim stop or Event messages, depending on MMTel service behaviour (detailed in clause 5.2.2). Within the CDF, the CDRs triggering follows the same principle as described for SIP sessions in TS 32.260 [20]: MMTel CDR is opened upon reception of a Charging Data Request [start] message, closed upon reception of a Charging Data Request [stop] message, updated upon reception of a Charging Data Request [Interim], and created upon reception of a Charging Data Request [event].

6.1.3.3 MMTel-AS CDR content

The MMTel CDR content and format description is based on TS 32.260 [20] AS-CDR description, enhanced with specific MMTel information.

6.2.1.0 Introduction

For online charging, the different service CTFs supporting MMTel specific service charging, generate debit and reserve units information transferred to the OCF. For this purpose, MMTel online charging utilises the Debit Units and Reserve Units procedure specified in the Debit / Reserve Units operation in TS 32.299 [50].
