A.1 Scope of signalling flows

24.1033GPPRelease 17Stage 3Telepresence using the IP Multimedia (IM) Core Network (CN) Subsystem (IMS)TS

Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

This annex gives examples of signalling flows for an IM session supporting telepresence based on the Session Initiation Protocol (SIP), SIP Events, the Session Description Protocol (SDP) and the CLUE protocol.

These signalling flows provide detailed flows, which expand on the overview conference information flows provided in 3GPP TS 24.147 [3].

These signalling flows are simplified in that they do not show the interactions between Intermediate IMS networks, nor the interactions between the AS and MRF.
