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 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.
A method, performed by a secondary node (SN) in a New Radio-New Radio Dual Connectivity (NR-DC) cellular communication system including a master node (MN), of reporting SN data usage for billing different tariffs of a user equipment's (UE's) usage over Frequency Range 1 (FR1) and Frequency Range 2 (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, the SN operating according to a same radio access technology (RAT) as 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 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 to a 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;
- 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;
- 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
- receiving, by a session management function (SMF) of a Fifth Generation (5G) core network of the NR-DC cellular communication system from the AMF, a first message, referred to as a N session management function protocol data unit session update session management context message (Nsmf_PDUSession_UpdateSMContext message), the Nsmf_PDUSession_UpdateSMContext message including the second data usage report representing the SN data usage by the UE;
- forwarding, by the SMF to the charging function, the SN data usage report;
- and
- providing, by the SMF to the AMF, a second message, referred to as an N session management function protocol data unit session update session management context response message (Nsmf_PDUSession_UpdateSMContextResponse message).
