[{"name":"S2-2202775","title":"Reply LS on mandatory SSC modes supported by UE","source":"CT WG1","contact":"Mikael Wass","contact-id":42217,"tdoctype":"LS in","for":"Action","abstract":"CT WG1 thanks SA WG2 for the LS on mandatory SSC modes supported by UE. CT WG1 has discussed SSC mode related requirements in current specification under CT WG1 control, and concluded the following: - support of at least one SSC mode is mandated; - mandatory support for any specific SSC mode is not explicitly stated in CT WG1 stage 3 specification; - functional requirements indicate that SSC mode 1 is the only SSC mode that is mandated to be supported by all UEs. CT WG1 further notes the recent LS from SA WG2 (S2-2201274 \/ C1-221751) with attached CRs that update stage 2 such that SSC mode 1 is mandatory to support for UEs supporting PDU connectivity, whereas SSC modes 2 and 3 are optional. These requirements are not captured in current CT WG1 specification, but CT WG1 intends to address these with corresponding updates in a future meeting. Action: CT WG1 kindly requests SA WG2 to take the above information into account.","secretary_remarks":"Noted","agenda_item_sort_order":6,"ainumber":"4.1","ainame":"Common issues and Incoming LSs","tdoc_agenda_sort_order":10410,"status":"noted","reservation_date":"2022-03-29 15:34:29","uploaded":"2022-03-29 17:47:55","revisionof":"","revisedto":"","release":"Rel-15","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"SA WG2","Cc":"CT WG6","lsoriginalls":"C1-222033","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/tsg_sa\/WG2_Arch\/TSGS2_150E_Electronic_2022-04\/Docs\/S2-2202775.zip","group":"S2","meeting":"S2-150-e","year":2022,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0}]
