The present document specifies the protocol of communication in the 5G System between:
- the SMF/CUC and the (R)AN/AN-TL, and
- the SMF/CUC and the UPF/CN-TL,
when the (R)AN and the UPF support the Talker and Listener functionality, for the support of Time Sensitive Networking (TSN) enabled Transport Network (TN) as specified in clauses 4.4.8, 5.28a and Annex M of 3GPP TS 23.501 [2] and Annex F of 3GPP TS 23.502 [3].
