CT WG1 would like to inform SA WG2 that CT WG1 assumes that the maximum number of MBS sessions that can be associated with a PDU session is limited to four and has agreed to introduce this in 3GPP TS 24.501. The consequence is that the NAS protocol can support a maximum of four MBS sessions associated with a PDU session. Action: CT WG1 kindly asks SA WG2 to take the above information into consideration. If SA WG2 has any concern with this assumption or any resulting limitation, then SA WG2 can kindly provide feedback.","secretary_remarks":"Response drafted in S2-2108404.

MBS service area (MBS SAI list, cell ID list, geographical area information or civic address information) may be included in the service announcement for local multicast MBS service or broadcast MBS service.

RAN WG2 notes that SA WG2 did not get consensus on whether frequency can be provided in the upper layer signalling, which goes against the working assumption made by RAN WG2 during RAN WG2#115-e meeting. RAN WG2 discussed this topic further during RAN#116-e meeting and made an agreement that frequency information in upper layer signalling is useful for some MBS use cases. This, for example, includes the cases where a certain MBS service is deployed homogeneously on a single frequency in a broadcast area, which is a likely deployment for some services. In such cases, it may be more efficient to directly provide the service-frequency mapping in upper layer signalling to decrease overhead over the air interface. Therefore, RAN WG2 would like to request SA WG2 to allow a possibility of including MBS service to frequency mapping in upper layer signalling in their specifications, similarly as in the case of USD in MBMS. Action: RAN WG2 respectfully asks SA WG2 to take the above information into account and allow a possibility of including MBS service to frequency mapping in upper layer signalling in their specifications.","secretary_remarks":"Noted","agenda_item_sort_order":52,"ainumber":"8.9","ainame":"Architectural enhancements for 5G multicast-broadcast services (5MBS)","tdoc_agenda_sort_order":16490,"status":"noted","reservation_date":"2021-11-12 06:29:25","uploaded":"2021-11-12 06:29:54","revisionof":"","revisedto":"","release":"Rel-17","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"SA WG2","Cc":"SA WG4, SA WG6, RAN WG3","lsoriginalls":"R2-2111511","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/tsg_sa\/WG2_Arch\/TSGS2_148E_Electronic_2021-11\/Docs\/S2-2108991.zip","group":"S2","meeting":"S2-148-e","year":2021,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},

The latter switch means a bearer type change from DRB to MRB during which the target gNB could buffer the data received from the shared N3 tunnel in order to re-send them over the MRB RLC PTP leg of the UE to fill the gap. This solution however typically leads to duplicate packets for the UE. One way for target gNB to eliminate duplicates would simply be if packets sent over the individual delivery unicast N3 could have the same CN SN (Sequence Number) than the same packet sent over the shared N3. Another possibility would be to rely on the fact that the UP-transmission times on N3 and RAN internal interfaces between individual delivery and shared delivery are fairly aligned and the gap that would be induced is in practice related to the HO process itself only. Action: RAN WG3 kindly ask SA WG2 whether the SA WG2 would be fine to accept the HO performance resulting from the 2nd option, otherwise, to comment on the 1st option.","secretary_remarks":"Response drafted in S2-2109013.
