Emergency Call Solutions
Developing Tomorrow's solutions
Horizon Connect provides end-to-end eCall solutions for automotive OEMs and Tier-1 suppliers — from concept to certification.
Our mission: enable faster emergency response, global compliance, and seamless integration of vehicle-to-infrastructure communication.
What is eCall?
eCall (Emergency Call System) is a European-mandated safety feature that automatically contacts emergency services (112) in the event of a serious accident.
-
Transfers a Minimum Set of Data (MSD) — including vehicle location, time, direction, and crash data — to the nearest Public Safety Answering Point (PSAP).
-
Supports manual SOS calls (MEC) and automatic crash notifications (ACN).
-
Reduces response time by up to 50% in rural areas and 40% in cities, saving lives every day
1
Legal SOS (EU eCall)
Uses 2G/3G networks to transmit the MSD over the voice channel via an in-band modem — the mandatory system across the EU since 2018
2
Private SOS
Operates over 4G (LTE) / 5G (NR) networks, sending the MSD through SIP INVITE and SMS to a Trusted Service Provider (TSP) such as Bosch
3
Next-Generation eCall
Future-proof, IMS-based eCall over 4G/5G, replacing 2G/3G. Supports voice, data, and IP connectivity for faster emergency communications
