6.1.1.0 Introduction

The IMS nodes generate accounting information that can be transferred from the CTF to the CDF. For this purpose, IMS offline charging utilises the Charging Data Transfer that is specified in the 3GPP accounting application described in TS 32.299 [50].

The Charging Data Transfer operation employs the Charging Data Request and Charging Data Response messages. Table 6.1.1.0.1 describes the use of these messages for offline charging.

6.1.3 CDR description on the Bi interface

6.1.3.1 CDR content description

The following standard CDR content and format are considered:

– S-CSCF-CDR generated based on information from the S-CSCF

– I-CSCF-CDR generated based on information from the I-CSCF

– P-CSCF-CDR generated based on information from the P-CSCF

– BGCF-CDR generated based on information from the BGCF

– IBCF-CDR generated based on information from the IBCF

– MGCF-CDR generated based on information from the MGCF

– MRFC-CDR generated based on information from the MRFC

– AS-CDR generated based on information from the AS

– E-CSCF-CDR generated based on information from the E-CSCF

– TF-CDR generated based on information from the IMS TF

– TRF-CDR generated based on information from the TRF

– ATCF-CDR generated based on information from the ATCF

The content of each CDR type is defined in the tables in clauses 6.1.3.3 to 6.14.3.1. For each CDR type the field definition includes the CDR parameter ("field name"), category and description. The categories in the tables are used according to the charging data configuration defined in clause 5.4 of TS 32.240 [1].

Editor’s Note: Equipment vendors shall be able to provide all of the fields listed in the CDR content table in order to claim compliance with the present document. However, since CDR processing and transport consume network resources, operators may opt to eliminate some of the fields that are not essential for their operation.

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 3GPP standardisation.

6.1.3.2 CDR triggers

6.1.3.2.1 Session related CDRs

Reflecting the usage of multimedia sessions IMS CDRs are generated by the CDF on a per session level. In the scope of the present document the term "session" refers always to a SIP session. The coherent media components are reflected inside the session CDRs with a media component container comprising of all the information necessary for the description of a media component.

Accounting information for SIP sessions is transferred from the CTF involved in the session to the CDF using Charging Data Request[start, interim and stop] messages. A session CDR is opened in the CDF upon reception of a Charging Data Request[start] message. Partial CDRs may be generated upon reception of a Charging Data Request[interim] message, which is sent by the network entity towards the CDF due to a session modification procedure (i.e. change in media). Session CDRs are updated, or partial CDRs are generated upon reception of a Charging Data Request[Interim] message, which is sent by the network entity due to expiration of the Charging Data Interim Interval. The CDF closes the final session CDR upon reception of a Charging Data Request[stop] message, which indicates that the SIP session is terminated. Further details on triggers for the generation of IMS CDRs are specified in [1].

Accounting information for unsuccessful session set-up attempts may be sent by the CTF to the CDF employing the Charging Data Request[event] message. The behaviour of the CDF upon receiving Charging Data Request [event] messages is specified in clause 6.1.3.2.2.

6.1.3.2.2 Session unrelated CDRs

To reflect chargeable events not directly related to a session the CDF may generate CDRs upon the occurrence of session unrelated SIP procedures, such as registration respectively de-registration events. Accounting information for SIP session-unrelated procedures is transferred from the IMS nodes involved in the procedure to the CDF using Charging Data Request[event] messages. Session unrelated CDRs are created in the CDF in a "one-off" action based on the information contained in the Charging Data Request[event] message. One session unrelated CDR is created in the CDF for each Charging Data Request[event] message received, whereas the creation of partial CDRs is not applicable for session unrelated CDRs. The cases for which the IMS nodes send Charging Data Request[event] messages are listed per SIP procedure in table 5.2.1.1 and table 5.2.1.2.

Further details on triggers for the generation of IMS CDRs are specified in clause 5.2.2.
