Communication technologies test laboratory Cetecom Advanced has certified the test solution from Rohde & Schwarz for the verification of the next generation (NG) eCall functionality. The solution is based on the CMX500 radio communication tester with the NG eCall option, which was specifically developed for the requirements of the IP Multimedia Subsystem (IMS)-based emergency call system.
NG eCall is the IMS-based development of the European eCall system. In contrast to the legacy, circuit-switched technology, NG eCall is based on packet-switched communication over 4G/5G networks. This improves not only speech and data transmission but also provides the foundation for future-proof telematics services.
The test solution from Rohde & Schwarz enables a complete end-to-end simulation of a 4G or 5G network and a public safety answering point (PSAP). It supports both IMS call setup and IP-based data transmission in accordance with the current 3GPP specifications as well as the CEN standards for NG eCall. The CMX-KA098 option has successfully completed the test scenarios for the PSAP part in accordance with the EN 17240:2024 standard — a crucial step for conformity with European requirements for NG eCall test systems.
Cetecom Advanced uses the solution for functional tests and protocol conformity tests as well as for the type-approval of in-vehicle systems (IVS) that implement NG eCall. The test environment allows for the simulation of real-world mobile network conditions and the emulation of various network scenarios — a significant advantage in preparing for certifications or the market launch of new vehicle models.
"The certification of Rohde & Schwarz’ test solution is a major milestone for us," said Thomas Reschka, senior technical consultant at cetecom advanced. "With this solution, we are technologically well-equipped for the requirements of IMS-based emergency call communication and can support our customers in the development and type-approval of NG eCall systems."
“The partnership with cetecom advanced allows us to offer innovative test solutions that meet the highest safety standards,” said Christoph Pointner, senior vice president mobile radio testers at Rohde & Schwarz. "With our NG eCall test solution, we support automotive manufacturers in developing and implementing life-saving technologies.”
Through this collaboration, both companies aim to empower the automotive industry to ensure the rapid adoption of next-generation vehicle communications that prioritize safety.
