The TR 26.959 v 1.0.0 includes example mechanisms to indicate at setup a terminal's ability to send adaptation triggers, e.g., to adapt to the most robust codec mode and using application layer redundancy. The report also includes preliminary study on the impact of jitter buffer management (JBM) and packet loss concealment (PLC) on handover thresholds.  Changes since last presentation: This is the first presentation.  Outstanding Issues: - Progress work on Maximum packet loss rate (PLR) operating points for speech codecs - Progress work on Signaling Methods based on Application Layer Redundancy - Progress work on analysis of dynamic allocation of uplink Max. PLR and downlink Max. PLR  Contentious Issues: None.","secretary_remarks":"Noted","agenda_item_sort_order":144,"ainumber":"17D.","ainame":"(FS_eVoLP) - S4 aspects of FS_eVoLP","tdoc_agenda_sort_order":12070,"status":"noted","reservation_date":"2017-11-24 01:26:13","uploaded":"2017-11-30 07:59:10","revisionof":"","revisedto":"","release":"Rel-15","crspec":26.959,"crspecversion":"1.0.0","workitem":[{"winame":"FS_eVoLP"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/tsg_sa\/TSG_SA\/TSGS_78\/Docs\/SP-170833.zip","group":"SP","meeting":"SP-78","year":2017,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0}]
