Study on 5G charging for additional roaming scenarios and actors
The present document studies the potential use cases, requirements, and solutions for the 5G charging for additional roaming scenarios and actors, in regards to roaming local break out and home routed and taking the requirements brought by adoption of GSMA BCE (Billing Charging Evolution), as a replacement for TAP.
The study will cover and identify gaps for:
- charging in the visited MNO network for the purpose of wholesale charging towards the home MNO
- capabilities for reconciliation of wholesale charging reports from the visited MNO network with MNO home network information
- charging in the visited MNO network and convey it to the home MNO network for the purpose of retail charging
- charging in the MNO’s network for the purpose of wholesale charging towards an additional charging model actor e.g. MVNO
- charging in the visited MNO network and convey it to the home MNO’s network for the purpose of home MNO wholesale charging towards an additional charging model actor e.g. MVNO
- charging in the visited MNO network and convey it to an MVNO hosted by a home MNO for the purpose of retail charging
