1  Scopep. 11

The present document continues the study on charging aspects of network slicing covered by TR 32.845 but no longer limited to charging data collection functionalities without quota management as specified for Network Slice management charging in TS 28.202 and for Network slice performance and analytics charging in TS 28.201.
The following is studied:
  • Network slice converged charging for Network Slices enabled over 3GPP 5GS;
  • Correlation aspects between Network Slice charging and the end user charging accessing the Network Slice;
  • Inter-Provider (B2B) charging aspects by considering the different Organizations (e.g. MNO, Verticals).
The Converged Charging service aspects associated to the TR 23.700-40 conclusion on network slice information is also considered.
