This TS specifies the Offline and Online Charging description for the Short Message Service (SMS), based on the functional description in TS 23.040
and on the SMS over IP in TS 23.204
. This TS does not replace existing offline SMS charging functionality and therefore is in addition to that defined in TS 32.250
and TS 32.251
This charging description includes the offline and online charging architecture and scenarios specific to SMS, as well as the mapping of the common 3GPP charging architecture (specified in TS 32.240
) onto SMS. It further specifies the structure and content of the CDRs for offline charging, and the charging events for online charging.
