Section: 5.5.3.10 Charging principles for 5G non-roaming Mobile Virtual Network Operators (MVNOs) charging
Content: For scenarios in which subscribers have a subscription with an MVNO which allows usage of 5G data connectivity while in the home MNO, the MNO shall be able to collect charging information related to 5G data connectivity usage for each MVNO, for wholesale. The MVNO deploys their own billing and charging (CHF), but no other NFs. The charging mechanism in the MNO collects charging information related to the 5G data connectivity usage for each UE and conveys this charging information to the MVNO for each UE. The MVNO uses the charging information collected for retail charging (MVNO to subscriber). Charging for MVNO scenario is covered by the 5G data connectivity domain converged charging architecture specified in TS 32.255[ Telecommunication management; Charging management; 5G data connectivity domain charging; Stage 2 ]  [15]. N47 reference point is also used when an additional actor (i.e. MVNO) performs retail charging for its own subscribers. In such a case N47 is the reference point between SMF in the MNO and CHF in the MVNO.
