1.Jan 1, 2026 Cutoff: All new vehicle type approval & existing homologation extension applications for M1/N1 passenger vehicles get rejected if equipped with legacy 2G/3G CS-domain traditional eCall. Legacy T-box and cellular modules supporting only 2G/3G voice circuit can no longer obtain new EU vehicle certification approval. Already homologated in-production vehicle models keep valid CoC certificate for continuous manufacturing without version upgrade or homologation expansion per EU transitional policy.
2.Jan 1, 2027 Hard Deadline: All M1/N1 vehicles approved under old (EU)2015/758 regulation without NG eCall configuration lose CoC validity and are banned from EU vehicle registration and road access under EU vehicle framework regulation (EU)2018/858 Article 48.
Core Technical Difference Between Legacy CS eCall and NG eCall
1.Conventional eCall relies on 2G/3G circuit-switch network to establish voice call and transmit 140-byte MSD V2 dataset via in-band modem after call setup, blocking parallel voice & data transmission. Phased global 2G/3G network shutdown makes legacy eCall technically unsustainable.
2.NG eCall builds on LTE/5G packet-switch IMS architecture, delivering upgraded MSD V3 data through SIP INVITE message over IP layer with simultaneous voice & data transmission without waiting for dataset completion. MSD V3 abandons 140-byte limit to store crash severity, EV battery status, passenger quantity and vehicle rollover angle; VoLTE high-definition voice plus multi-constellation GNSS delivers 1~3m positioning accuracy under open sky while canyon/indoor signal attenuation leads to unavoidable positioning deviation beyond the standard benchmark.
NG eCall Core Standard Framework
Two core EN harmonized standards dominate NG eCall compliance: EN 17184:2024 defines IMS/LTE-NR upper-layer application protocol for IVS terminals; EN 17240:2024 specifies full end-to-end conformance test cases covering IVS, MNO operator and PSAP emergency answering platform. UN R144 revised 2024 amendment regulates vehicle-level functional safety while EN 50685 sets PSAP platform construction specifications.
Three-Tier Full-Scope Certification Structure (All tiers required for final approval)
1.Component-level IVS/T-box Test: Mandatory GNSS positioning accuracy test, backup battery endurance test (minimum 10min runtime after main power cut-off) and extreme high/low temperature environmental reliability verification against datasheet nominal parameters.
2.Protocol Conformance Test: Strict SIP signaling interaction, MSD V3 codec, PLMN roaming registration and CLB recall data update validation per EN17240. Special regulation for eCall-only devices: prohibited persistent SIP session attachment under standby status; permanent long-connection firmware design directly fails certification audit. Around 20 mandatory test items plus 30 conditional accelerated test cases apply for IVS protocol validation.
3.Full Vehicle-level Certification: Crash trigger verification, full-vehicle EMC immunity test, automotive audio compliance per ITU-T P.1140:2021 and on-board network communication stability testing. Modification of CAN bus signal or crash sensor threshold triggers full retest with high R&D cost.Optimized parallel project arrangement shortens full certification from standard 3~6 months to 2~4 months with professional project management.
UN R144 Certificate Validity & Annual COP Audit Rules
Component NG eCall E-mark certificate holds lifelong validity as long as product design and referenced standards remain unchanged without fixed 3-year expiry. Annual on-site COP production consistency audit executed by notified NB bodies to verify mass-produced goods match certified prototype on design, BOM and manufacturing process. Factories with valid IATF16949 qualification qualify for remote COP audit instead of on-site inspection. Full vehicle E-mark certificate follows vehicle homologation lifecycle and invalidates upon vehicle discontinuation or core hardware revision.
Global Fragmented eCall Regional Compliance Standards
Besides EU regulation and China domestic AECS GB45672-2025 standard, UAE enforces UAE.S 5019:2024 NG eCall specification and GCC countries align with unified GSO technical rules; Russia & EAEU ERA-GLONASS certification combines domestic GOST standards plus supplementary UN R144 local clauses with standalone EMC, communication and navigation testing. UN R144 acts as basic global framework but each jurisdiction releases localized addendums with non-interchangeable regional certification certificates.
