The digitalization of the automotive sector is profoundly transforming the way vehicles interact with transport infrastructure and emergency services.
One of the most significant advances in this field has been the introduction of the eCall system, a technology designed to enable vehicles to automatically make an emergency call to the number 112 in the event of an accident.
This system, promoted by the European Union, aims to reduce emergency response times and improve road safety.
With the evolution of telecommunications networks and the adoption of IP architectures, the system is evolving toward a new generation known as Next Generation eCall (NG eCall).
What is the eCall system
The eCall system is a safety solution that allows vehicles to automatically send an emergency call when a serious accident is detected.
This call is made to the European emergency number 112, which connects directly to PSAPs (Public Safety Answering Points), or emergency call centers.
The objective of the system is to provide emergency services with immediate information about the accident, enabling faster deployment of resources.
The role of the IVS (In Vehicle System)
The main component of the eCall system is the IVS (In Vehicle System), a device installed in the vehicle that is responsible for detecting accidents and activating the emergency call.
This system can be activated in two ways:
- automatically through vehicle sensors
- manually via an emergency button
When activated, the IVS establishes communication with the emergency center and transmits relevant information about the incident.
Minimum Set of Data (MSD)
During an eCall, the vehicle transmits a set of data known as the Minimum Set of Data (MSD).
This data set includes essential information for emergency services, such as:
- vehicle GPS location
- direction of travel
- vehicle identification
- fuel type
- estimated number of occupants
This information allows PSAP operators to quickly assess the severity of the accident and deploy the appropriate resources.
Evolution toward Next Generation eCall
The original eCall system was designed to operate over traditional telecommunications networks.
However, the transition to IP networks has driven the development of Next Generation eCall (NGeCall).
NGeCall introduces significant improvements in terms of interoperability, data transmission, and compatibility with NG112 architectures.
Among the advantages of NGeCall are:
- better integration with NG112 platforms
- more efficient data transmission
- greater interoperability between systems
- compatibility with modern IP networks
Integration with emergency communication platforms
For the eCall system to function properly, emergency centers must have platforms capable of managing this type of communication.
These platforms must be able to:
- receive eCall calls
- decode the Minimum Set of Data
- present the information to the operator
- integrate with CAD and GIS systems
The integration of these capabilities into critical communication platforms allows emergency centers to manage these calls efficiently.
Impact on road safety
Various studies have shown that the eCall system can significantly reduce emergency service response times.
The immediate availability of vehicle location information enables faster resource deployment.
In urban areas, response times can be reduced by up to 40%, while in rural areas improvements can be even greater.
With the evolution toward Next Generation eCall, these capabilities will continue to improve and contribute to strengthening road safety in Europe.
