The liaison was reviewed at the Q13\/15 meeting held during the SG15 Plenary (19-30 September 2022). The following questions were discussed, and answers are provided below: What type of information about the 5GS time source are relevant to determine that it deteriorates and may impact time synchronization services already in place for the User Equipment (UEs)? What information made available by the 5GS to the UE would be sufficient to enable applications in a UE or device attached to the UE to compare the 5GS clock against other clocks that may be locally available to the applications in the UE\/devices attached to the UE so that the best available clock can be selected? {. . .}","secretary_remarks":"Revision of S2-2300011.

RAN WG2 had discussions on the alternatives from SA WG2 and would like to provide the following feedback: From RAN WG2 point of view, if the information is not UE specific and is required in IDLE and INACTIVE mode then we can use SIB to broadcast the information, but SIB size matters in RAN WG2 so keeping the size of information reasonable is important. If dedicated information is required, from RAN WG2 perspective, it would be good to avoid all UEs going to connected at the same time. We would like to also point out in connected mode the UE can be provided with more accurate information. Besides, RAN WG2 would like to know whether the information needs to be based on UE subscription and\/or be ciphered which would impact the solution. Action: RAN WG2 respectfully asks SA WG2 to take the feedback into account and provide further information if any.","secretary_remarks":"Revision of S2-2300043.
