[{"name":"S2-2502803","title":"LS from CT WG1: LS on stage 1 requirements for the support for PWS over satellite NGRAN in Rel-17","source":"CT WG1","contact":"Amer Catovic","contact-id":39766,"tdoctype":"LS in","for":"Information","abstract":"SA WG1 has agreed to introduce a new requirement for the support for PWS over satellite NG-RAN (CR#0081 to TS 22.268 in S1-244777) from Rel-17. CT WG1 has discussed the stage 2 aspects of this requirement and determined that this requirement would have UE impacts that would create backward compatibility issues (e.g. country-specific duplicate detection timers for PLMNs using non-country specific PLMN ID with MCC 9xx over satellite access). Consequently, CT WG1 has decided to introduce the support for PWS over satellite NG-RAN in Rel-19. This work will be done under the new CT-wide Rel-19 work item on the support for PWS over satellite E-UTRAN and satellite NG-RAN. CT WG1 kindly asks SA WG1 to align their specifications accordingly.","secretary_remarks":"Postponed in parallel session","agenda_item_sort_order":54,"ainumber":"8.11","ainame":"Architecture aspects for using satellite access in 5G (5GSAT_ARCH)","tdoc_agenda_sort_order":10780,"status":"postponed","reservation_date":"2025-03-22 07:08:23","uploaded":"2025-03-22 13:14:35","revisionof":"","revisedto":"S2-2504572","release":"","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"SA WG1","Cc":"SA WG2, CT WG4, RAN WG2","lsoriginalls":"C1-250715","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/tsg_sa\/WG2_Arch\/TSGS2_168_Goteborg_2025-04\/Docs\/S2-2502803.zip","group":"S2","meeting":"S2-168","year":2025,"uicc_affected":"","me_affected":"","ran_affected":"","cn_affected":"","clauses_affected":"","crsinpack":null,"crsinpacknumber":0}]
