Where it stands

AI traffic characterisation

Via the 5G-MAG testbed: 11+ scenarios and 60+ KPIs, including time-to-first-token, time-per-output-token, uplink/downlink ratio and an agent loop factor.

Adjacent SA4 work

IVAS immersive voice and audio (Release 19, deployment-ready) and FS_Avatar_Ph2 on avatar calls over IMS.

Open questions

Whether SA4 proposes new QoS characteristics or traffic models — And how they would reach SA2's 6G QoS framework.

Watch next

March 2027 — Study due.
