[{"name":"S4-191141","title":"Considerations on multicast support in 5GMS","source":"TELUS","contact":"PENG TAN","contact-id":82945,"tdoctype":"discussion","for":"Agreement","abstract":"5GMS[1] has provided general description and architecture on MNO and 3rd party media downlink streaming services, and MNO and 3rd party media uplink streaming services. Although most of MNO and 3rd party media services are unicast-based Adaptive Bit Rate (ABR) streaming [28], there is still important existence of operator videos services based on multicast. Specially, studies in [2] and [26] identified a couple of IPTV use cases and their solutions.\n\nIt is true that more and more OTT video streaming options is becoming available nowadays. However, OTT video streaming itself is facing QoE and scalability challenges. To make good use of scarce spectrum resources, in addition to edge caching, CDN, multicast ABR, including its usage in 5G has been actively investigated by the industry as well.\n\nMulticast-based IPTV plays important role in worldwide pay-tv market. In certain markets, the number of IPTV subscribers are still increasing. As 5G fixed wireless access enters into mass deployment, in addition to \u201cconnect the unconnected\u201d, 5G fixed wireless access is also regarded as a segment where full IPTV offering could be provided to enhance ARPU and justify operators\u2019 5G investment.\n\nBroadcast\/Multicast is viewed as one of a basic capability of 5G, it is not well addressed though. This proposal recommends multicast-based streaming service is included in the 5GMS spec as well. The rest of this document is organized as follows. Section 2 gives a review of multicast-related standard and work in 3GPP. Section 3 and section 4 suggest some potential multicast enhancements, and potential places we could insert into 5GMS respectively. Lastly, we seek for agreement to look at this topic, and fill the multicast gap which has not been well address in 5G series of 3GPP spces.","secretary_remarks":"","agenda_item_sort_order":30,"ainumber":"8.1","ainame":"New Work \/ New Work Items and Study Items","tdoc_agenda_sort_order":0,"status":"noted","reservation_date":"2019-10-14 15:35:28","uploaded":"2019-10-15 02:34:49","revisionof":"","revisedto":"","release":"","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/TSG_SA\/WG4_CODEC\/TSGS4_106_Busan\/Docs\/S4-191141.zip","group":"S4","meeting":"S4-106","year":2019,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},
