Abstract
Disclosed are techniques for reporting secondary node (SN) data usage in an NR-DC cellular communication for billing different tariffs of a UE's data usage over FR1 and FR2 bands provided by, respectively, a master node (MN) and a secondary node (SN). Also disclosed are details of the messages exchanged in various NR-DC architectures. In some embodiments, an SMF is configured for selecting a CHF from a CHF pool based on various factors.

A method, performed by a master node (MN) in an NR-DC cellular communication system including a secondary node (SN), of reporting SN data usage for billing different tariffs of a UE's data usage over FR1 and FR2 bands provided by the MN and the SN, respectively, the method comprising:
- receiving from the SN a first SN data usage report, the first SN data usage report representing the SN data usage by the UE;
- generating 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 the second SN data usage report to the AMF to facilitate reporting of the SN data usage to a charging function and billing system.
A method, performed by a secondary node (SN) in an NR-DC cellular communication system including a master node (MN), of reporting SN data usage for billing different tariffs of a UE's data usage over FR1 and FR2 bands provided by the MN and the SN, respectively, the method comprising:
- receiving from the MN an SN data usage report configuration;
- generating, based on the SN data usage report configuration, an SN data usage report for the MN;
- and
- providing the SN data usage report to the MN to facilitate reporting of the SN data usage to a core network.
A method, performed by a session management function (SMF) in 5G core network of an NR-DC cellular communication system including a master node (MN) and secondary node (SN), of reporting SN data usage for billing different tariffs of a UE's data usage over FR1 and FR2 bands provided by the MN and the SN, respectively, the method comprising:
- receiving from an access management function (AMF) an Nsmf_PDUSession_UpdateSMContext message, the Nsmf_PDUSession_UpdateSMContext message including an SN data usage report representing the SN data usage by the UE;
- forwarding to a charging function (CHF) the SN data usage report;
- and
- providing to the AMF an Nsmf_PDUSession_UpdateSMContextResponse message.
