1  Scope  p. 7

The present document is part of a series of documents that specify charging functionality and charging management in 3GPP networks. The 3GPP core network charging architecture and principles are specified in TS 32.240, which provides an umbrella for other charging management TSs that specify:
  • the content of the CDRs per domain / subsystem / service (offline charging);
  • the content of real-time charging messages per domain / subsystem / service (online charging);
  • the functionality of online and offline charging for those domains / subsystems / services;
  • the interfaces that are used in the charging framework to transfer the charging information (i.e. CDRs or charging events).
The complete document structure for these TSs is defined in TS 32.240.
The present document specifies the converged charging description for the 5G MBS Session based on the functional stage 2 description in TS 23.247, TS 23.501, TS 23.502 and TS 23.503.
This charging description includes the converged charging architecture and scenarios specific to the 5G MBS Session, with focus on the following charging scenarios:
  • MBS session charging for multicast communication.
  • MBS session charging for broadcast communication.
It further specifies the structure and content of the CDRs and the charging events for converged charging.
All references, abbreviations, definitions, descriptions, principles and requirements, used in the present document, that are common across 3GPP TSs, are defined in TR 21.905. Those that are common across charging management in 3GPP networks/domains, services or subsystems are provided in the umbrella TS 32.240 and are copied into clause 3 of the present document for ease of reading. Finally, those items that are specific to the present document are defined exclusively in the present document.

4.2  5G MBS Session converged charging architecture  p. 9

In order to support MBS session charging, the MB-SMF embedding the CTF, generates charging events towards the CHF for converged charging.
Figure 4.2-1 depicts the 5G MBS architectural options for converged charging in service-based representation, with MB-SMF interacting with CHF.
