More specifically, common solution framework for both trusted and untrusted non-3GPP accesses. The study was focusing on the following: - How the 5GC and the 5G UE can support traffic steering, switching and splitting between 3GPP and non-3GPP accesses over a multi-access PDU session, including the required performance measurements to support ATSSS operation decision. - How to enable ATSSSs architecture framework to support IP and Ethernet traffic - How the multi-access traffic steering, switching and splitting (ATSSS) can be taken into account by the charging framework in order to enable the network operator to differentiate charging for data traffic that is switched and\/or split between 3GPP and non-3GPP accesses. - How to incorporate the support for MPTCP transpor","secretary_remarks":"Approved","agenda_item_sort_order":114,"ainumber":"17B.4","ainame":"(FS_ATSSS) - Study on Access Traffic Steering, Switch and Splitting support in the 5G system architecture","tdoc_agenda_sort_order":12120,"status":"approved","reservation_date":"2018-12-03 11:12:35","uploaded":"2018-12-06 17:27:56","revisionof":"","revisedto":"","release":"Rel-16","crspec":23.793,"crspecversion":"2.0.0","workitem":[{"winame":"FS_ATSSS"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/tsg_sa\/TSG_SA\/TSGS_82\/Docs\/SP-181098.zip","group":"SP","meeting":"SP-82","year":2018,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0}]
