What we do

The objective of the TTF T017 is the enhancement of interoperability tests under ETSI TS 103 683 to cover latest ETSI/3GPP and CEN base specifications.

For more details, see our Terms of Reference

Why we do it

ETSI has organized the first NG eCall interoperability event. This remote event was hosted by SINTESIO, from 2 to 6 November 2020 in Kranj, Slovenia ( see 1st NG eCall Plugtests). More than 20 vendors were present during the plugtest preparation phase but later on 6 vendors attended the remote interoperability event.

The aim of the event was to trial independently and jointly IVS and PSAP devices based on Next Generation eCall over MNO network. Due to the pandemic situation simplified network without LTE was used to check interoperability between IVSs and PSAPs.

The existing interoperability test specification needs to be enhanced to be ready for the next NG eCall Plugtests event planned in Q3 2022.

How we do it

The leading body is TC MSG, any reports, drafts and final deliverables are discussed with and presented to TC MSG.
