112 readiness
Policy, location, routing, and response quality connected in one operational model.
eCall and NG eCall
NG eCall
NG eCall and NG112 are related but distinct. NG eCall addresses how vehicles access emergency services as mobile networks evolve, while NG112 covers the broader emergency communications architecture around 112.
What it does
NG eCall is the next-generation evolution of vehicle emergency calling toward modern IP/IMS mobile environments.
NG eCall intersects with NG112 where vehicle-originated emergency sessions and data enter next-generation emergency networks and PSAPs.
How it works
- Uses modern mobile emergency architecture rather than relying on legacy circuit-switched assumptions.
- Carries vehicle and incident data toward PSAP systems.
- Requires PSAP readiness for evolved data and session behavior.
Key interfaces and protocols
- IMS emergency calling
- Vehicle data/MSD
- Mobile network interconnect
- PSAP eCall handling
Systems it interacts with
- IMS emergency calling
- VoLTE
- VoNR
- eCall
- eCall MSD
- PSAP
Common failure modes
- Network sunset occurs before NG eCall readiness.
- Vehicle data reaches a platform but not the call taker.
- Roaming vehicle behavior is under-tested.
- PSAP accepts voice but not evolved data.
Implementation considerations
- Coordinate mobile operators, vehicle ecosystem and PSAPs.
- Use Plugtests output for interoperability planning.
- Avoid describing NG eCall as a full NG112 deployment.
Standards
- 3GPP IMS emergency references
- ETSI NG112/NG eCall Plugtests
