Body 
During the ITU-T Study Group 11 interim Rapporteur Group meeting (e-meeting, 7
-16 July 2021), Q1/11 (Signalling and protocol architectures for
telecommunication networks and guidelines for implementations) has created a
new work item Q.DC-SA “Signalling architecture of data channel enhanced IMS
network” (SG11-TD102/WP1).

ITU-T Q.DC-SA provides the signalling architecture of data channel enhanced IMS
network. It presents the overview of data channel technology and discusses the
research on data channel based IMS network. It also analyzes the necessities of
research on signalling architecture of data channel based IMS network and
specifies the framework and interfaces of data channel enhanced IMS network.
This draft Recommendation will build on 3GPP TS 26.114, IETF RFC8831 and ITU-T
Y.3104 and will be aligned with them. ITU-T Q1/11 would like to thank you for
your attention, feedback and cooperation on this topic.

The description of the new work item Q.DC-SA is available in the Q1/11 report
as highlighted in A.1 justification form (see Annex B of the report).
