The cell switch command indicates an LTM candidate configuration that the gNB previously prepared and provided to the UE through RRC signalling. Then the UE switches to the target configuration according to the cell switch command. Currently in Rel-18, LTM operation is only supported for mobility between cells within a gNB i.e., both intra-gNB-DU and intra-gNB-CU inter-gNB-DU (same CU) mobility. In release-19, it is planned to enable it for between cells of different gNBs (inter-CU). Further, for L3 mobility enhancement Conditional Handover (CHO) and conditional mobility procedures (CPAC, SCPAC) were developed to achieve high robustness by enabling the procedure to be executed without necessitating a signalling exchange with source cell beforehand. L3 based handover is performed over RRC and is protected using the AS security context. Whereas no security procedure is defined for protection over MAC (for L1\/L2 triggered mobility). Therefore, based on RAN WG2 progress on defining LTM for inter-CU in the NR mobility enhancements Phase 4 (NR_Mob_Ph4), it is required in SA WG3 needs to define the security procedure required for the re-keying needed for L1\/L2 based handover.","secretary_remarks":"Revised to SP-240999","agenda_item_sort_order":43,"ainumber":"6.2.3","ainame":"SA WG3 and SA WG3-LI New Release 19 Work Item Descriptions","tdoc_agenda_sort_order":11080,"status":"revised","reservation_date":"2024-06-04 13:11:24","uploaded":"2024-06-07 08:47:06","revisionof":"","revisedto":"SP-240999","release":"","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/TSG_SA\/TSG_SA\/TSGS_104_Shanghai_2024-06\/Docs\/SP-240652.zip","group":"SP","meeting":"SP-104","year":2024,"uicc_affected":"","me_affected":"","ran_affected":"","cn_affected":"","clauses_affected":"","crsinpack":null,"crsinpacknumber":0},
