1. A method, performed in a New Radio-New Radio Dual Connectivity (NR-DC) cellular communication system including a master node (MN) and a secondary node (SN), of reporting SN data usage for billing different tariffs of a UE's data-user equipment's (UE's) data usage over Frequency Range 1 (FR1) and Frequency Range 2 (FR2) bands provided by the MN and the SN, respectively, the method comprising:
receiving, by the MN from the SN, a first SN data usage report, the first SN data usage report representing the SN data usage by the UE, the MN operating according to a same radio access technology (RAT) as the SN;
generating, by the MN, a second SN data usage report for an access management function (AMF), the second SN data usage report representing the SN data usage by the UE; and
providing, by the MN, the second SN data usage report to the AMF to facilitate reporting of the SN data usage to a charging function and billing system.
