On the other hand, Annex B.3.1 and B.3.2 specify that the 'MBSTF' provides the MBSTF tunnel endpoint address to the MBS Application Provider (AF\/AS). It is CT WG4's understanding that the MBSTF tunnel endpoint address is assigned by MBSTF, and hence may be present in the response sent by MBSTF upon receiving the Nmbstf_MBSDistributionSession_Create request from the MBSF. {. . .}","secretary_remarks":"Noted","agenda_item_sort_order":52,"ainumber":"8.9","ainame":"Architectural enhancements for 5G multicast-broadcast services (5MBS)","tdoc_agenda_sort_order":12450,"status":"noted","reservation_date":"2022-04-21 14:48:20","uploaded":"2022-04-22 05:13:38","revisionof":"","revisedto":"","release":"Rel-17","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"SA WG4","Cc":"CT WG3, SA WG2","lsoriginalls":"C4-222300","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/tsg_sa\/WG2_Arch\/TSGS2_151E_Electronic_2022-05\/Docs\/S2-2203647.zip","group":"S2","meeting":"S2-151-e","year":2022,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0}]
