"3GPP enablers for OMA PoC Services", in OMA-AD-POC "Push to talk over Cellular (PoC) - Architecture", in OMA-CP-POC "OMA PoC Control Plane" and in OMA-UP-POC: "OMA POC User Plane", respectively.
This charging description includes the offline and online charging architecture and scenarios specific to PoC, as well as the mapping of the common 3GPP charging architecture specified in TS 32.240
onto the PoC service. It further specifies the structure and content of the CDRs for offline charging, and the charging events for online charging.
