This TS specifies the online charging description for Voice Call Service (VCS) charging from a Proxy
Function, based on the functional description of the Voice Call Service charging in the EU Roaming Regulations III
The concept of voice call is interpreted as any CS call, whatever the teleservice used (speech, 3.1 kHz audio, Fax, or CS
data) except CS video telephony calls (BS 37, 64 kbit/s unrestricted digital info mode).
Voice over LTE is not included in this definition. This charging specification includes the online charging architecture
and scenarios specific to VCS charging from a Proxy Function, as well as the mapping of the common 3GPP charging
architecture specified in TS 32.240
onto VCS. It further specifies the charging events for online charging. The
present document is related to other 3GPP charging TSs as follows:
The common 3GPP charging architecture is specified in TS 32.240;
The 3GPP Diameter application that is used for VCS online charging is specified in TS 32.299.
Offline charging for the VCS is solely based on TS 32.250 and is outside the scope of the present document.
