CT1 also observed that the serving GW will likely be changed during inter-MME connected mode mobility.\nFor the intra-MME mobility cases, CT1 observed a NAS based DL data retransmission solution at the MME is feasible to provide lossless data transmission. However, for the inter-MME mobility cases, CT1 does not see any feasible solution so far for the DL.\nCT1 would like SA2 to discuss this issue and conclude a feasible solution to provide DL lossless data transmission for NB-IoT CP solution during inter-MME connected mode mobility.","secretary_remarks":"","agenda_item_sort_order":7,"ainumber":"4","ainame":"Input liaison statements: allocation to agenda items as appropriate","tdoc_agenda_sort_order":0,"status":"noted","reservation_date":"2017-03-22 08:53:17","uploaded":"2017-03-22 09:25:31","revisionof":"","revisedto":"","release":"Rel-14","crspec":"","crspecversion":"","workitem":[{"winame":"CIoT_Ext-CT"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"3GPP TSG SA WG2","Cc":"3GPP TSG RAN WG2, 3GPP TSG RAN WG3, 3GPP TSG CT WG4","lsoriginalls":"C1-170886","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/tsg_ct\/WG4_protocollars_ex-CN4\/TSGCT4_77_Spokane\/Docs\/C4-172082.zip","group":"C4","meeting":"C4-77","year":2017,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},
