More specifically, the following MTSI enhancements are addressed, and the related gap analysis and conclusions are documented:  1. Potential recommendations for MTSI on the available mechanisms in TS 26.114 to determine the content of UEAssistanceInformation messages with delay budget report information  2. Potential recommendations on how RAN-level delay budget reporting works in conjunction with existing media adaptation behaviours in TS 26.114 for MTSI.  3. Identification and definition of potential new formats for real-time signalling of delay budget information from an MTSI receiver to an MTSI sender during a multimedia telephony session are also considered. Furthermore, end-to-end performance evaluations for MTSI are presented, based on end-to-end metrics such as delay, jitter and packet loss rate, in conjunction with RAN-level a","secretary_remarks":"Noted","agenda_item_sort_order":172,"ainumber":"17D.1","ainame":"(FS_E2E_DELAY) - Study on Media Handling Aspects of RAN Delay Budget Reporting in MTSI","tdoc_agenda_sort_order":12800,"status":"noted","reservation_date":"2018-05-08 09:05:10","uploaded":"2018-05-28 09:00:19","revisionof":"","revisedto":"","release":"Rel-15","crspec":26.91,"crspecversion":"1.0.0","workitem":[{"winame":"FS_E2E_DELAY"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/tsg_sa\/TSG_SA\/TSGS_80\/Docs\/SP-180281.zip","group":"SP","meeting":"SP-80","year":2018,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0}]
