[{"name":"S2-2200047","title":"Reply LS on LCS MO-LR Procedure in 5G","source":"CT WG1","contact":"Maurice Pope","contact-id":648,"tdoctype":"LS in","for":"Information","abstract":"CT WG1 thanks CT WG4 for the LS on LCS MO-LR procedure in 5G and would like to provide following feedback on the three questions asked in the LS. Q1: In 5GC-MO-LR procedure, which information (GMLC Number or H-GMLC Address) is actually provided by the UE and used by the AMF to select the (H-)GMLC? Answer 1: In Rel-16, only the 'mlc-number' is provided by the UE in MO-LR procedure. The attachment C1-216845 which is agreed in CT WG1#133e removes 'h-gmlc-address' from LCS-MOLR invoke in MO-LR procedure. Please check the attached CR for details. Q2: In 5GC-MO-LR procedure, which information (LCS Service Type or Service Identity) is actually provided by the UE and used by the GMLC to perform service privacy check? Answer 2: In TS 24.571, it is 'LCSServiceTypeID' as defined in TS 29.002 provided by the UE in MO-LR procedure. The 'LCSServiceTypeID' corresponds to the term 'Service Type' in TS 23.273 as clarified in S2-2107864 (TS 23.273 CR0193). Q3: What's the consideration of backward compatibility with early release of LCS, if SA WG2\/CT WG1 decides to select new mechanism different from 4G LCS? Answer 3: The attached CR to include only 'mlc-number' in LCS-MOLR invoke in MO-LR procedure is backward compatible with TS 24.571 v16.2.0 and the earlier versions.","secretary_remarks":"Noted","agenda_item_sort_order":31,"ainumber":"7.6","ainame":"Enhancement to the 5GC Location Services (5G_eLCS)","tdoc_agenda_sort_order":11330,"status":"noted","reservation_date":"2022-01-10 14:20:56","uploaded":"2022-01-10 16:05:25","revisionof":"","revisedto":"","release":"Rel-16","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"CT WG4","Cc":"SA WG2","lsoriginalls":"C1-217277","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/tsg_sa\/WG2_Arch\/TSGS2_149E_Electronic_2022-02\/Docs\/S2-2200047.zip","group":"S2","meeting":"S2-149-e","year":2022,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0}]
