This LS is acknowledging SA WG3 s Objective: for 5G SA roaming to address certain security shortcomings in 2G-4G roaming, most notably the lack of end-to-end security in the signalling between VPLMN and HPLMN. This design principle is also the ultimate Objective: for the work in GSMA NG 5GMRR, which seeks a solution that achieves this Objective: while still allowing roaming hub business. Please note that GSMA NG 5GMRR is sending in two separate LS items in response to S3-234350 on the topic of Modified PRINS for both Roaming Hub (this LS) and for IPX Service Hub (the accompanying LS).","secretary_remarks":"Noted","agenda_item_sort_order":9,"ainumber":"2.1","ainame":"Incoming LSs - proposed to note","tdoc_agenda_sort_order":10100,"status":"noted","reservation_date":"2023-11-07 10:19:15","uploaded":"2023-11-10 10:01:12","revisionof":"","revisedto":"","release":"","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"SA WG3","Cc":"TSG SA, SA WG1, TSG CT, CT WG4","lsoriginalls":"5GMRR Doc 45_13r7","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/TSG_SA\/TSG_SA\/TSGS_102_Edinburgh_2023-12\/Docs\/SP-231219.zip","group":"SP","meeting":"SP-102","year":2023,"uicc_affected":"","me_affected":"","ran_affected":"","cn_affected":"","clauses_affected":"","crsinpack":null,"crsinpacknumber":0}]
