[{"name":"S2-2306284","title":"LS from SA WG6: LS on addressing packet loss during multicast MBS delivery","source":"SA WG6","contact":"Yanmei Yang","contact-id":37039,"tdoctype":"LS in","for":"Action","abstract":"In SA WG6 there were concerns that packet loss could happen in multicast MBS delivery due to AF being not aware of the multicast MBS session state in some cases, e.g.: - A talker starts to speak to the group after a silent period with no DL media. The media packet from the talker needs to be delivered via the multicast MBS session. - The multicast MBS session is configured and the group members have joined in advance. After a while, the application layer signalling, e.g., group call request, MapGroupToSessionStream, floor taken needs to be delivered via the multicast MBS session. During the silent period without DL media, the multicast MBS session used for this group communication might become inactive and the joined UEs become IDLE. The new DL packets trigger the multicast MBS session being activated and the IDLE UEs being paged. However, not all the UEs become CONNECTED at the same time. The late CONNECTED UEs will lose the packet as the NG-RAN will start to transmit the packet when the first UE becomes CONNECTED which triggers the shared delivery restoring again. SA WG6 would like to request SA WG2 to provide their feedback on the above scenario. Action: SA WG6 kindly asks SA WG2 to provide their feedback on the above scenario.","secretary_remarks":"Revision of Postponed S2-2303985 from S2#156E.

SA WG6 has concerns that failure may occur once the AF triggers the MBS session update with a new MBS service area, i.e., during the MBS service area update, the AF may receive the following error described in 3GPP TS 29.522 in Table 5.20.7.3-1: UNKNOWN_MBS_SERVICE_AREA . SA WG6 would like to ask SA WG2, CT WG3 and CT WG4 the following questions: Q1. SA WG6 would like to ask SA WG2 whether the AF\/NEF will interact with the NRF to re-select the capable MB-SMF during the MBS session update with requested MBS service area? Q2. SA WG6 would like to ask CT WG3 and CT WG4 to clarify the scenario(s) when the error UNKNOWN_MBS_SERVICE_AREA 404 Not Found The requested MBS service area (e.g. identified by the Area Session ID) cannot be found. in 3GPP TS 29.522 can occur? Is the MBS service area not found in MB-SMF, NRF or NEF? Can it occur during MBS session update? Q3. SA WG6 would like to ask SA WG2 to confirm whether the scenarios described above from SA WG6, CT WG4 and CT WG3 can occur during MBS session update. If yes, what are the mechanism(s) defined by SA WG2 to be employed to overcome an MBS session update failure?. Action: SA WG6 kindly asks SA WG2, CT WG3 and CT WG4 to consider above questions and provide the feedback.","secretary_remarks":"Responses drafted in S2-2306338, S2-2306450, S2-2306743, S2-2306801.
