[{"name":"S2-2202782","title":"LS from CT WG4: LS on Traffic usage reporting on 5MBS service","source":"CT WG4","contact":"yong yang","contact-id":59744,"tdoctype":"LS in","for":"Action","abstract":"CT WG4 discussed how a Usage Reporting Rule should be provisioned over N4mb and be enforced in MB-UPF. SA WG2 has a requirement 'traffic usage reporting based on existing means.' as specified in clause 5.3.2.4 of TS 23.247. The traffic usage is measured when the packets are delivered to the downstream node. However, for a MBS session, when unicast transport is used, the same copy of the MBS session data will be replicated to all the DL tunnels towards concerning NG-RANs and\/or UPFs. CT WG4 would like to ask how MBS session data should be measured in MB-UPF? In addition, whether all measurement methods, i.e. per volume, duration (i.e. time) and\/or events, and all Reporting Triggers should be applicable for N4mb?. Action: CT WG4 kindly asks SA WG2 group to answer CT WG4 questions and consider clarifying stage 2 accordingly, if necessary.","secretary_remarks":"Response drafted in S2-2202142.
