This TS covers all internal aspects of the Online Charging System (OCS). This TS contains the architecture and functions of the OCS logical components and thereby derives the functionality of the OCS interfaces. A detailed specification of interfaces between the logical OCS components is also included. The functionality of the OCS, as described in this TS, applies to all charging domains (bearer, session and service).
This TS is limited to the interface between the charging function and the Rating Function, namely Re
. The interfaces connecting to the OCS (e.g. Ro, CAP) are out of the scope of this TS.
