CT4 would like to answer to the question as below. \n\nSA5 Question:\nAccording 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.\nConsidering the above information and charging requirements, SA5 has the following question:\nIs 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?\n\nCT4 Answer:\nThe UE supporting UAS services provides CAA-level UAV ID included in the Service-level-AA container IE to the AMF\/SMF during the registration procedure\/PDU session establishment procedure as described in clause 4.22 of 3GPP TS 24.501, Authentication and authorization of UAV. Accordingly, the AMF\/SMF can identify the UE is an UAV UE or requesting UAV services.","secretary_remarks":"","agenda_item_sort_order":10,"ainumber":"5.3","ainame":"Liaison statements at SA5 level","tdoc_agenda_sort_order":43170,"status":"noted","reservation_date":"2025-10-01 15:34:44","uploaded":"2025-10-01 16:20:27","revisionof":"","revisedto":"","release":"Rel-19","crspec":"","crspecversion":"","workitem":[{"winame":"UAS_Ph3-CH"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/ftp\/tsg_sa\/WG5_TM\/TSGS5_163\/Docs\/S5-254317.zip","group":"S5","meeting":"S5-163","year":2025,"uicc_affected":"","me_affected":"","ran_affected":"","cn_affected":"","clauses_affected":"","crsinpack":null,"crsinpacknumber":0}]
