This TS specifies the Proxy Function in Domestic Service Provider (DSP).
The present document contains the architecture and functions of the Proxy Function logical components and thereby
derives the functionality of the Proxy Function interfaces. This charging description only defines the interworking
between CAMEL and Diameter. The Ro interface between the Proxy Function and Online Charging System (OCS) is
out of scope of the present document.
The present document is related to other 3GPP charging TSs as follows:
The common 3GPP charging architecture is specified in TS 32.240;
Voice Call Service (VCS) charging is specified in TS 32.276.
