One of the key issues is converged charging with UAV Information, with the requirement to identify the UAV. To support charging aspects of UAS, SA WG5 agreed on the new WID on Charging for Uncrewed Aerial Systems Phase 3, specifying charging enhancements to support converged charging with UAV Information and expecting to make it possible for charging differentiation. According to TS 23.256, a UAV that is configured for UAS services (i.e. is provisioned with a CAA-Level UAV ID) registers to the 3GPP system for UAS services and provides the CAA-Level UAV ID and a UUAA Aviation Payload to 5GS or EPS. As defined in TS 24.501, the CAA-Level UAV ID is provided to 5GC with the value of service-level device ID setting to the CAA-Level UAV ID. Considering the above information and charging requirements, SA WG5 has the following question: Is there any attribute already defined in Rel-19 CT specifications indicating AMF and SMF that a UE is a UAV UE or is using UAS services?","secretary_remarks":"Noted in parallel session","agenda_item_sort_order":121,"ainumber":"19.10.2","ainame":"Phase 3 for UAS, UAV and UAM (UAS_Ph3)","tdoc_agenda_sort_order":14830,"status":"noted","reservation_date":"2025-06-26 15:02:10","uploaded":"2025-06-27 12:04:46","revisionof":"","revisedto":"","release":"Rel-19","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"CT WG4, CT WG3","Cc":"SA WG2","lsoriginalls":"S5-252788","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/tsg_sa\/WG2_Arch\/TSGS2_170_Goteborg_2025-08\/Docs\/S2-2506160.zip","group":"S2","meeting":"S2-170","year":2025,"uicc_affected":"","me_affected":"","ran_affected":"","cn_affected":"","clauses_affected":"","crsinpack":null,"crsinpacknumber":0},
