Anritsu and LG Electronics have completed the verification of the hybrid eCall operation of the in-vehicle system. It is significant in that it confirmed the continuity of emergency call services even in an environment where cellular network transitions are underway and demonstrated compliance with the latest European eCall standards.

Anritsu Corporation and LG Electronics announced on the 27th that LG’s in-vehicle system (IVS) meets hybrid eCall requirements.

This verification focused on confirming whether the emergency call service operates normally in an environment where legacy circuit-switched networks and next-generation packet-switched networks coexist.

This joint verification was conducted using Anritsu's eCall evaluation solution.

The solution is equipment that has obtained European standard EN 18052:2025 certification for hybrid eCall and was used to verify the end-to-end operation of the eCall service chain in an environment where circuit switching (2G/3G) and packet switching (4G/LTE IMS) methods are mixed.

Verification results confirmed that LG's in-vehicle system meets the functions and interoperability requirements defined in Hybrid eCall.

It is reported that this has secured the foundation to maintain the continuity of emergency call services even during the mobile communication network transition process.

Hybrid eCall is designed to support next-generation eCall (NG eCall) utilizing the IP Multimedia Subsystem (IMS) in packet-switched networks while maintaining backward compatibility with existing circuit-switched networks.

In Europe, regulations are evolving in a direction that strengthens the requirements for NG eCall compatibility during the type approval process for new vehicle models.

Accordingly, verifying hybrid eCall operation in a mixed network environment is considered an essential step in confirming future regulatory compliance.

This verification is a case study checking the system's readiness in preparation for this transition period.It was introduced as.

Shinji Hoshino of Anritsu’s IoT Test Solutions Division stated, “Hybrid eCall requires strict requirements for end-to-end interoperability between heterogeneous network technologies,” adding, “Through this verification, we have achieved compliance with the latest European eCall standards.”

Kim Hong-duk, Senior Vice President in charge of connectivity development at LG Electronics’ VS Division, stated, “We confirmed that the in-vehicle system can support hybrid eCall requirements during Europe’s transition to NG eCall,” adding, “We were able to verify eCall performance that meets current European conformity standards.”

Meanwhile, the verified hybrid eCall configuration was demonstrated at the 5G Automotive Association (5GAA) event held in Gothenburg, Sweden on the 23rd, and a standard-based verification case in an actual network test environment was shared with stakeholders.
