Still a few operators wants RAN5 work towards the earlier requested target completion by end of 2020.\nThe outcome of the poll was also reflected in the RAN5 chair report to RAN#87 plenary in March-20 (RP-200011):\nSA Option 5 & NSA Options 4 and 7\nAnonymous re-polling of MNOs conducted on deployment interest and timelines\nMNOs confirmed deployment interests and RAN5 conformance tests need date of end of 2020\nNetwork infrastructure dependency could delay deployment timelines\nRAN5 test definition phase planning postponed to RAN5#87 (May) meeting\nRAN5 cannot spend reserved TTCN budget until network infrastructure support is confirmed\n\nThe purpose of this document is to propose the way forward for SA Option 5 and NSA Option 4 and 7 in RAN5.\nConsidering that \n3GPP is contribution driven\nRAN5 resources and TTCN funding are limited\nSA Option 2 and NSA Option 3 already are deployed in networks and part of UE certification schemes\n\u2026.. the following way forward is proposed: _x00B_\nWork plans & contributions\nVolunteers interested in option 4, 5 and 7 need to support current work plan owners to drive update of impacted work plans for option 4, 5 and 7.\nExecution of work plans for option 4, 5 and 7 follows RAN5 business a usual, i.e. contribution driven by interested companies._x00B_\nMeeting priorities\nSA Option 2 and NSA Option 3 have higher priority @RAN5 meetings than option 4,5 and 7_x00B_\nImpact on completion of 5GS Rel-15 WI\nIn case options 4,5 and 7 are not completed when NR SA and EN-DC are considered completed, and the activity level is low for options 4,5 and 7, RAN5 may decide to close the Rel-15 5GS work item and leave remaining parts for options 4,5, and 7 for TEI.","secretary_remarks":"","agenda_item_sort_order":28,"ainumber":"7.2.5","ainame":"Other","tdoc_agenda_sort_order":255600,"status":"noted","reservation_date":"2020-06-01 16:31:05","uploaded":"2020-06-10 14:56:20","revisionof":"","revisedto":"","release":"","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_87_Electronic\/Docs\/R5-202556.zip","group":"R5","meeting":"R5-ah-38102","year":2020,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0}]
