This is feasible and CT1 does not see any issue with this Option.\n\u2022\tOption 2 will not require any CT1 specification changes but will have more system-level impact than Option 1 as it will require adding support for request of ciphering keys by the UE in an MO-LR message, conveying the request from an MME to an E-SMLC, and adding support for the E-SMLC to send the ciphering keys to the UE using LPP. These changes are within CT4\u2019s and RAN2\u2019s remit.\nConsequently CT1 thinks Option 1 is a preferable way forward from a system-level point of view.","secretary_remarks":"","agenda_item_sort_order":53,"ainumber":"6.3.13","ainame":"Any other business","tdoc_agenda_sort_order":0,"status":"noted","reservation_date":"2018-02-15 16:27:05","uploaded":"2018-02-15 16:51:56","revisionof":"","revisedto":"","release":"Rel-15","crspec":"","crspecversion":"","workitem":[{"winame":"LCS_LTE_acc_enh-Core"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"S2-179617","lsto":"SA2","Cc":"RAN3, RAN2, CT4, SA3","lsoriginalls":"C1-180643","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/tsg_ct\/WG4_protocollars_ex-CN4\/TSGCT4_83_Montreal\/Docs\/C4-182209.zip","group":"C4","meeting":"C4-83","year":2018,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0}]
