[{"name":"S2-1901440","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 would like to inform SA WG2 that during our SA WG4#102 meeting we have agreed on the attached draft CR to TS 26.114 to enable SDP-based signalling of ANBR capabilities based on the newly defined 'anbr' SDP attribute. Combined with the SA WG2-described solution where the PCRF\/PCF is configured with knowledge of PLMN-wide support of ANBR, this should enable end-to-end coordination of ANBR capabilities across the UEs, Access Networks, and PCRF\/PCF. Since the UEs will not know the ANBR capabilities of the eNB\/gNBs they are connected to during the SDP-based session setup, the P-CSCF serving the PLMN is expected to only pass through the 'anbr' attribute in the SDP when it knows that the PLMN supports ANBR functionality. SA WG4 is concerned that the proposed solution requires that deployed P-CSCFs in networks that currently do not support ANBR will remove the 'anbr' SDP attribute. Can SA WG2 clarify whether the SA WG2 specifications already recommend this behaviour, i.e., removing unrecognized SDP attributes, in the P-CSCF? Assuming a positive response, SA WG4 will agree on the attached draft CR to support the solution and kindly requests that SA WG2 update its specifications as needed. Action: SA WG4 kindly asks SA WG2 to consider the above and inform SA WG4 if any modifications are required to the proposed solution, and notify SA WG4 when SA WG2 has standardized any necessary procedures.","secretary_remarks":"Response drafted in S2-1901475.
