[{"name":"S2-1904899","title":"LS from SA WG4: Reply LS on Informing PCF\/PCRF of End-to-end RAN Assisted Codec Adaptation (ANBR) Support","source":"SA WG4","contact":"Ozgur Oyman","contact-id":44803,"tdoctype":"LS in","for":"Action","abstract":"SA WG4 thanks SA WG2 for their reply LS on Informing PCF\/PCRF of End-to-end RAN Assisted Codec Adaptation (ANBR) Support. We are glad to learn that SA WG2 discussed the legacy P-CSCF issue and agreed that this issue can be resolved during the SIP registration where the P-CSCF indicates its ability to recognize the 'anbr' SDP attribute to the UE and then the UE would only include 'anbr' in the SDP offer if the corresponding P-CSCF understands it. Based on this development, we would like to inform you that we have agreed to the attached CR to TS 26.114 on signalling of ANBR capabilities that introduces the 'anbr' SDP attribute. SA WG4 also respectfully asks CT WG1 to update the relevant Stage 3 specifications in order to support the SIP registration procedure where the P-CSCF indicates its ability to recognize the 'anbr' SDP attribute. Furthermore, SA WG4 asks CT WG1 to enable any core network support necessary for the newly defined SDP attribute 'anbr', e.g., at a minimum this new SDP attribute needs to be introduced into TS 24.229. Action: SA WG4 kindly asks SA WG2 to consider the above and provide any further feedback.","secretary_remarks":"Noted in parallel session","agenda_item_sort_order":17,"ainumber":"6.4","ainame":"Rel-16 IMS-Related Maintenance - essential corrections - Excluding R15\/R16 5GS maintenance","tdoc_agenda_sort_order":10520,"status":"noted","reservation_date":"2019-04-23 11:45:51","uploaded":"2019-04-23 13:14:44","revisionof":"","revisedto":"","release":"","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"SA WG2, CT WG1","Cc":"","lsoriginalls":"S4-190490","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/tsg_sa\/WG2_Arch\/TSGS2_133_Reno\/Docs\/S2-1904899.zip","group":"S2","meeting":"S2-133","year":2019,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},
