Transforming emergency response: the rise of Intelligent Transport Systems with eCall HLAP

In the dynamic realm of Intelligent Transport Systems (ITS), a revolutionary document is shaping the future of emergency response. This ground-breaking initiative focuses on integrating eCall HLAP (high-level application protocols) into hybrid circuit-switched/packet-switched network environments, catering to the 112-eCall service across Europe.

The core objective is clear: to uniformly automate traffic accident notification throughout Europe. Operating under EN 16072:2022, this initiative leverages a Public Land Mobile Network (PLMN), like the ETSI prime medium, supporting the 112/E112 European harmonized emergency number. The system ensures a standardized and reliable emergency communication framework, whether through TS12 ETSI TS 122 003 or the IMS packet-switched network.


What sets this innovation apart is its adaptability to both circuit-switched and packet-switched wireless networks. This flexibility is vital in the current landscape of coexisting communication infrastructures. The integration of eCall HLAP is the technological backbone, navigating seamlessly between networks for swift and effective emergency response.


Crucially, the system does not overlook the human touch. It provides a manual triggering mechanism, empowering individuals to promptly notify emergency services of critical incidents. This dual capability underscores the versatility and user-centric design of the pan-European in-vehicle emergency call system (eCall).


EN 17905:2023, a standard recently published by CEN/TC 278 (whose Secretariat is held by NEN, the Dutch National Standardization Body), is the driving force behind this transformative shift. This collaborative effort is a significant step towards harmonizing European emergency response protocols, ensuring a safer and more connected transport ecosystem.


In conclusion, integrating eCall HLAP in hybrid circuit-switched/packet-switched network environments marks a pivotal moment in the evolution of ITS. This initiative automates emergency responses and incorporates human intervention, promising a unified and efficient emergency response system across the European landscape.
