CT WG1 would like to ask SA WG2 the following questions: Q1: Is the presence of DC media description in the SDP offer of an initial INVITE request from the originating network mandatory condition for the terminating IMS AS to notify the DCSF? Q2: If the answer on Q1 is No, the SDP offer in an initial INVITE request from the originating network does not contain DC media description and the terminating UE has IMS DC capability and subscription, can the terminating IMS AS notify the DCSF based on the operator policy? Q3: If the answer on Q1 is No and Q2 is Yes, after the terminating IMS AS notifies the DCSF, is the DCSF allowed to instruct the IMS AS to set up bootstrap data channel between the terminating network and terminating UE if the SDP offer of an initial INVITE request from the originating network does not contain DC media description?

SA WG3 provides the following response: Q1: Would SA WG3 see any requirement of mandating the usage of IMS media plane encryption? A1: In 3GPP, there is no requirement of mandating the usage of IMS media plane confidentiality, but for IMS Data Channel media SA WG3 understands that RFC 8831 is referred by 3GPP to implement the protocol stack of IMS Data Channel media that includes DTLS. Q2: Could you confirm that the MNO can choose whether to encrypt IMS audio and video media during the media negotiation with UE, in IMS? A2: Yes, only in the case for non-DC media, the MNO can choose whether to encrypt IMS audio and video media during the UE registration in IMS. Q3: Could the MNO choose whether to encrypt DC media during the media negotiation with UE, similar to how they can choose to encrypt IMS audio and video media? A3: SA WG3 understands that MNO can not choose whether to encrypt IMS Data Channel media now, because RFC 8831 is referred by 3GPP to implement the protocol stack of IMS DC that includes DTLS.
