In Annex AG.1 of the CR, a note was added as below: NOTE: Privacy and security aspects regarding adding, removing, updating data channels by the network are under SA WG3 responsibility. According to workflows in Annex AG.2.1 of the CR, especially AG.2.1.Y (Adding P2P application data channel to an existing IMS session), the subscriber of the UE is not aware whether the DC is added by the DC application server instead of peer UE, hence may be misled to accept or reject the DC request. Similarly, the user may accept the DC terminating\/update request from the DC AS without being aware of request initiator. This is due to lack of transparency in the IMS DC session control procedure. It's essential to consider transparency to user during IMS Data Channel session control exposure. For example, the user may need to be aware that the DC adding, removing, updating request is initiated by the DC AS instead of the peer UE. SA WG3 kindly requests SA WG2 to take the above information into account and consider the transparency to user in their Rel-19 work on IMS Data Channel session control exposure. Action: SA WG3 kindly asks SA WG2 to take the information into account and consider the transparency to user in their Rel-19 work on IMS Data Channel session control exposure.","secretary_remarks":"Responses drafted in S2-2503314, S2-2503685.

Phase 1 of data channel specifies minimal set of requirements to support both the protocol UNI\/NNI interworking and the application layer API interworking. And currently GSMA members are submitting contributions to update GSMA PRD NG.134 [2] and GSMA PRD TS.66 [1] so they are in-line with 3GPP Rel-18 features. That work is expected to be completed by Q1.2025. GSMA TSG IMSDCAS members are now proposing new set of data channel requirements related to the feature 'Automatic Resume from the point where you have left off'. This feature is available on the digital platforms, e.g. YouTube, and provides both convenience and engagement benefits. The feature allows to continue interacting with the service from a last point that the user left off. People watching video or downloading files are well acquainted with this feature. In the rest of this text the feature will be referred in short as the Automatic Resumption. The use case details will be described in the next version of GSMA PRD NG.129. {. . .} Action: Request to SA WG2: GSMA TSG IMSDCAS kindly requests SA WG2 to help with the following clarifications related to the Automatic Resumption use cases and the technical feature 1. Confirm whether SA WG2 or SA WG4 has considered the use cases of the class 'Resume from the point where you have left off' and what was the conclusion on this topic? 2. Confirm whether the Automatic Resumption technical feature and state preservation might interact with any other 3GPP specified features? 3. Confirm whether the described feature is in any way related to the session continuity or might impact the supplementary services? 4. Confirm if SA WG2 plans to define and capture the requirements related to 'Automatic Resume from the point where you have left off' and whether SA WG2\/SA WG4 plans to specify technical solution for this feature? 5. Advice on the feasibility of described technical implementation? 6. Advise whether it would be possible to realize such state retention functionality without the need to introduce SDP modifications or any other modifications to the existing standards, i.e. by using session cookies, or exchanging the state data as part of application or bootstrap data channel protocol, including that of consensus? 7. Confirm whether SA WG2 \/ SA WG4 have considered scenarios where DCS stores an application context or other application data and DCS sends it as part of bootstrap process to UE or when a such data is requested by data channel application","secretary_remarks":"Response drafted in S2-2503170.

This event is detected when an IMS is in the process of being established, and a Notify is sent out as per clause AC.7.9.3. However, clause AC.7.9.4 includes 2 notifications related to the same event, one initiated by the IMS AS when the session is in the process of being established and the second one when the session is established as this is needed for this use case. The second Notify is not aligned with the event description. As is stands, looks like the event should report a Notify when the session is in the process of being established and when the session is established. Although only one is needed per use case, this is the one way to support the 2 cases with a single event otherwise 2 distinctive events are required, and the AS has to subscribe to both. Comments are inserted in the text. There is also additional inconsistency since it is unclear in AC.7.9.4 how the communication between UE#1 and the DC AS is established to enable interworking.
