**What is eCall?**
eCall is an automated emergency call system integrated into vehicles that, in the event of a crash, automatically dials emergency services and transmits critical information about the incident. This technology helps speed up response times and improve the chances of saving lives.
There are three key terms commonly used when discussing eCall in English documents:
- **Car System**: Known as the In-Vehicle System (IVS)
- **Call Center**: Referred to as the Public Safety Answering Point (PSAP), which can be compared to emergency services like 110 in China
- **Related Information**: Called the Minimum Set of Data (MSD), which includes details such as location, time, number of passengers, license plate, and other important data for rescue operations
It's worth noting that while eCall typically uses voice channels, data transmission via data channels is also possible, though the standard for this is still under development.
By instantly delivering accident details to the PSAP or Third Party Service Providers (TPSP), eCall enables faster emergency response, ultimately reducing casualties. The system can automatically send vehicle model, type, diagnostic data, and location information during emergencies, allowing rescue teams to respond more effectively.
In addition to the EU’s mandatory eCall requirements since April 2018, Russia has its own version called ERA-GLONASS, based on the GLONASS satellite navigation system.

**What Are the eCall Test Standards?**
Currently, eCall standards include:
1. **European eCall Standard**
2. **Russian ERA-GLONASS Standard** (based on the European one)
3. **Japanese Standard** (less widely adopted)
There are two ways to initiate an eCall:
- **Manual Trigger**: A driver presses the eCall button in the car.
- **Automatic Trigger**: Sensors detect a crash and trigger the call automatically.
The system will indicate whether the call was manually or automatically initiated. Once triggered, the vehicle sends the Minimum Set of Data (MSD) to the PSAP or TPSP. This data includes critical information like the vehicle’s location, time, number of passengers, and more.
The MSD consists of 140 bytes and is sent before the voice call is connected. It contains:
- Message identifier
- Reason for triggering (manual or automatic)
- Type of eCall (real or test)
- Vehicle type
- Unique vehicle ID
- Fuel type
- Timestamp
- GPS coordinates
- Location accuracy
- Direction of travel
- Optional historical location data
- Number of passengers
- And more
One of the main differences between eCall and regular emergency calls is that eCall is automatic, requires a collision detection system, and sends the MSD data. The MSD is transmitted before the voice call, and the phone is muted during this process. There are two modes: Push (initiated by the vehicle) and Pull (initiated by the PSAP).

**eCall Standards**
There are two major eCall standards:
- **PAN-EUROPEAN (EU Standard)**: Fully compliant with 3GPP standards
- **ERA-GLONASS (Russian Standard)**: Based on the GLONASS system, it is compatible with EU standards but has some differences, such as different redial mechanisms, additional optional data, and the ability to resend MSD via SMS if needed.
**3GPP Standards Related to eCall:**
- ETSI TS 126 267: eCall definition
- ETSI TS 126 267: eCall coding
- ETSI TS 126 267: eCall certification
**GLONASS Standards in Russia:**
- GOST 32450-2013: Technical requirements for automotive navigation equipment
- GOST R 54721-2011: Basic service description for road accident emergency response systems
- GOST R 54618-2011: Compliance test methods for electrical compatibility and mechanical resistance
- GOST R 54619-2011: Data transfer protocol for vehicle emergency call systems
- GOST R 54620-2011: General technical requirements for eCall systems
- GOST R 55530-2013: Function testing and data transfer protocol
- GOST R 55533-2013: Testing of wireless communication modules
These standards ensure that eCall systems are reliable, secure, and interoperable across different regions and platforms.
