The GSM and UMTS PLMN support a wide range of packet based services by means of the General Packet Radio Service (GPRS), as defined in TS 22.060
and TS 23.060
. In order to enable operators the ability to provide a commercially viable service, there is a need to provide charging functions. For GPRS these functions include the generation of Charging Data Records (CDRs) by the Serving GPRS Support Node (SGSN) and the Gateway GPRS Support Node (GGSN) as well as the transport of these CDRs to a Billing System (BS) through a Charging Gateway Function (CGF).
This TS is part of a series of documents specifying charging functionality in UMTS networks. The UMTS charging architecture and principles are specified in TS 32.200
which provides an umbrella for other charging documents that specify the structure and content of the CDRs and the interface protocol that is used to transfer them to the collecting node. The CDRs content and transport within the PS domain are described in this TS. The CDRs used in the Circuit Switched (CS) domain are specified in TS 32.205
while CDRs used for application services are defined in TS 32.235
