The EU's Next Generation eCall (NG eCall) certification represents a technological overhaul of the vehicle emergency call system, designed to replace the traditional 2G/3G-based eCall system. Below are the core certification standards, test items, and latest developments as of 2025, covering technical specifications, testing requirements, and compliance pathways.
| Dimension | NG eCall Standard Requirements | Traditional eCall Comparison |
| Regulatory Basis | (EU) 2015/758 (Framework Regulation) (EU) 2024/1180 (NG eCall Transitional Rules) | Traditional eCall only required (EU) 2015/758 |
| Technical Basis | 4G/5G Network + IMS (IP Multimedia Subsystem) Support for Packet Switching (VoLTE/ViLTE) | Based on 2G/3G Circuit-Switched Networks |
| Data Transmission | MSD V3 Format (Minimum Set of Data) Supports Video Streams, Sensor Data (Impact Severity, Battery Status, etc.) | MSD limited to 140 bytes (Text Data) |
| Positioning Accuracy | Dynamic Scenario Error ≤ 3 meters (Fused GNSS + Vehicle Sensors) | Traditional Requirement ≤ 150 meters (GPS only) |
| Network Compatibility | Mandatory support for 4G/5G full frequency bands (e.g., Band 20/28) Requires IMS Interoperability Testing | Only required 2G/3G network compatibility |
| Mandatory Timeline | 2026.01.01: New vehicle types must support NG eCall 2027.01.01: Traditional eCall certificates expire | Traditional systems banned after 2027 |
II.Key Test Item Details:
1.Protocol Conformance Testing:
·IMS Signaling Test: Validates SIP protocol session establishment, registration, emergency call routing (ETSI TS 103 683).
·Test Items: SDP Negotiation, Emergency Session Release, Fallback Mechanism (4G/5G → CS Voice).
2.SD V3 Data Transmission:
·Data Format Validation: Vehicle VIN, Location, Impact Severity, Seatbelt Status, Battery Level.
·Transmission Time Requirement: ≤ 5 seconds (Traditional eCall was ≤ 10 seconds).
3.Performance & Reliability Testing:
·Call Setup Time: ≤ 10 seconds from trigger to PSAP connection (Traditional eCall was ≤ 60 seconds).
·Positioning Performance:
Dynamic Scenario Testing: Error ≤ 3 meters in urban canyon, tunnel environments.
Test Standard: ETSI EN 303 413 (GNSS Receiver Performance).
·Power Failure Reliability: Backup battery must sustain system operation ≥ 10 minutes (post-crash power loss scenario).
4.Network & Interoperability Testing:
·Multi-Operator Compatibility: Interoperability with major EU operator networks (e.g., Deutsche Telekom, Orange). Tests end-to-end IMS emergency call connection (Vehicle → Operator Core Network → PSAP).
·Dual-Mode Fallback Mechanism: Automatic switch to legacy CS eCall when 4G/5G signal is weak (ensures call success rate).
5.Security & Privacy Testing:
·GDPR Compliance: Data encryption (AES-256), anonymization of location information. Privacy scheme must detail data storage period and deletion mechanisms.
·Cybersecurity: Prevention of malicious tampering with MSD data (UN R155 requirement).
III. New Test Items (2025 Update):
1.5G NR Connection Stability: Tests 5G link handover stability in high-speed scenarios (≥ 120 km/h).
2.Multi-Sensor Data Fusion: Verifies real-time synchronization of gyroscope, accelerometer data with MSD V3.
3.Video Stream Transmission Test: Optional functionality test: Evaluates 720p video stream transmission capability in weak network conditions (RSRP ≤ -110 dBm).
IV. Correlation with Other Regulations:
1.CE-RED Certification: If the eCall device contains wireless modules (e.g., 5G module), separate CE-RED certification (EN 303 413) is required.
2.UN R155 Cybersecurity: Requires a Cybersecurity Management System (CSMS) certificate.
The core of the EU NG eCall certification is the upgrade from "basic alarm" to "multi-dimensional data interaction," achieving high-precision positioning, video transmission, and real-time sensor data sharing via 4G/5G and IMS technologies. Companies should focus on IMS protocol conformance, dual-mode fallback mechanisms, and GDPR compliance, utilizing the 2025-2026 transition period to complete the technical migration.
