[{"name":"S2-1906842","title":"LS from SA WG4: LS on TS 26.501 5G Media Streaming (5GMS); General description and architecture","source":"SA WG4","contact":"Frederic Gabin","contact-id":18030,"tdoctype":"LS in","for":"Action","abstract":"SA WG4 has concluded work on 5G Media Streaming Architecture (5GMSA), where the architecture and procedures for the UE and Network Media Functions have been defined. 5GMSA differentiates between Downlink and Uplink media streaming functions. Downlink media streaming functions allow for content to be ingested and distributed over the 5GS, while leveraging the full potential and capabilities of 5G. Uplink media streaming addresses use cases where media content is captured by the UE and streamed uplink to the network for further distribution. In addition to the network media functions, 5GMSA also breaks down the UE into its logical media functions, each of which serves a different purpose. The identified interfaces are expected to be translated into Media API(s) in the stage 3 realizations. We would like to highlight that stage 3 work is expected to define usage of existing 5GS APIs e.g. to the NEF and PCF and to specify a new northbound API for media content ingest into an MNO operated CDN with possible media processing. SA WG4 would like to kindly ask SA WG2 to review the attached draft TS 26.501, in order to ensure that it is aligned with the 5GS architecture. We appreciate your comments on the specification and thank you in advance. Action: SA WG4 kindly asks to SA WG2 to take the above information into account and to provide SA WG4 with any comments that SA WG2 might have on the draft specification.","secretary_remarks":"Postponed S2-1905810 from S2#133.

{"name":"S2-1906847","title":"LS from TSG SA: LS on the scope of study\/work item on support for multi-USIM devices (FS_MUSIM\/MUSIM)","source":"TSG SA","contact":"Saso Stojanovski","contact-id":56758,"tdoctype":"LS in","for":"Action","abstract":"Triggered by an Editor's note in the Scope clause of TR 22.834 (SP-190318) submitted by SA WG1 for approval, SA#84 discussed the scope of the FS_MUSIM stage 1 study (SP-190241) and corresponding MUSIM stage 1 work item (SP-190309). SA#84 concluded that both EPS and 5GS are in the scope of the FS_MUSIM study and the MUSIM work item. Specifically, MUSIM shall define system enablers that apply to all of the following cases: 1. UE connected over 3GPP RAT with EPS on one USIM and 5GS on the other USIM. 2. UE connected over 3GPP RAT with EPS on both USIMs. 3. UE connected over 3GPP RAT with 5GS on both USIMs. It is noted that MUSIM is an optional feature for both the UE and the network (EPS or 5GS) that is intended to improve performance both on the UE side (e.g. avoidance of missed calls for Single Rx UEs caused by paging collisions) and on the network side (e.g. avoidance of distorted statistics) in all scenarios listed above. When MUSIM is not supported by the (EPS or 5GS) network, UEs supporting the MUSIM enablers are expected to have backup mechanisms to handle issues caused by the simultaneous operation with multiple USIMs (as is already the case with deployed UEs). In that sense, SA would like to stress that the deployment of MUSIM enablers in the network shall not have any impact on already deployed multi-USIM UEs that do not support the MUSIM enablers. SA is aware that the system impact of MUSIM in the access stratum may have dependency on the underlying RAT and that certain changes may be acceptable for one RAT only. SA expects that RAN will decide what kind of access stratum changes are acceptable for each RAT during the definition of their study on RAN aspects of MUSIM. Action: SA respectfully asks SA WG2 to take the feedback above into consideration during their study on FS_MUSIM stage 2.","secretary_remarks":"Noted","agenda_item_sort_order":6,"ainumber":"4.1","ainame":"Common issues and Incoming LSs","tdoc_agenda_sort_order":10090,"status":"noted","reservation_date":"2019-06-10 18:36:16","uploaded":"2019-06-12 11:37:53","revisionof":"","revisedto":"","release":"Rel-17","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"SA WG1, SA WG2, TSG RAN","Cc":"","lsoriginalls":"SP-190573","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/tsg_sa\/WG2_Arch\/TSGS2_134_Sapporo\/Docs\/S2-1906847.zip","group":"S2","meeting":"S2-134","year":2019,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},
