6.1A Rf message content

6.1A.0 General

This clause is applicable to the ePDG, TWAG, MME, S-GW, P-GW and TDF, when the CDF is provided as an external entity.

6.1A.1 Summary of offline charging message formats

The PS Offline Charging and ""SMS over MME 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.

The Charging Data Request can be of type [Start, Interim, Stop and Event] and includes all charging information. The Charging Data Response is an acknowledgement of the Charging Data Request.

Table 6.1A.1.1 describes the use of these messages for offline charging.

Feature bit: The order number of the bit within the Feature-List AVP where the least significant bit is assigned number "0". Feature: A short name that can be used to refer to the bit and to the feature, e.g. "EPS". Feature in this table is always mandatory since it relates to the charging functionality of a network feature. Description: A clear textual description of the feature.

6.3.2 Detailed message format for offline charging

The following clause specifies per Operation Type the charging data that are sent by MME, S-GW, ePDG, TWAG, P-GW and TDF.

The Operation Types are listed in the following order: S (Start)/I (Interim)/S (Stop)/E (Event). Therefore, when all Operation Types are possible it is marked as SISE. If only some Operation Types are allowed for a node, only the appropriate letters are used (i.e. SIS or E) as indicated in the table heading. The omission of an Operation Type for a particular field is marked with "-" (i.e. SI-E). Also, when an entire field is not allowed in a node the entire cell is marked as "-".

Table 6.3.2.1 illustrates the basic structure of the supported fields in the Charging Data Request message for PS offline charging.

6.3.3 Detailed message format for online charging

The following table specifies per Operation type the charging data that are sent P-GW and TDF network element for:

The Operation types are listed in the following order: I [initial]/U [update]/T [terminate]/E [event]. Therefore, when all Operation types are possible it is marked as IUTE. If only some Operation types are allowed for a node, only the appropriate letters are used (i.e. IUT or E) as indicated in the table heading. The omission of an Operation type for a particular field is marked with "-" (i.e. IU-E). Also, when an entire filed is not allowed in a node the entire cell is marked as "-".

Note that not for all structured fields the individual field members are listed in the table. Detailed descriptions of the fields are provided in TS 32.299 [50].

Table 6.3.3.1 illustrates the basic structure of the supported fields in the Debit / Reserve Units Request for PS online charging.
