How to Validate Next Generation eCall Conformance

+ eCall Conformance Test Solution

Validate NG eCall Behavior

Next generation eCall conformance testing requires a controlled environment that represents the in-vehicle system, Global Navigation Satellite System (GNSS), cellular network, and Public Safety Answering Point (PSAP). Engineers configure the emergency-call workflow so the in-vehicle system receives simulated position information, connects through an emulated mobile network, and interacts with the PSAP without using a live network. The setup supports next generation eCall alongside Pan-European eCall and ERA-GLONASS, allowing the same laboratory framework to exercise the emergency-call functions under repeatable network and positioning conditions. The cellular test environment can reproduce multiple network generations while keeping the call path under laboratory control.

During execution, the test verifies that the in-vehicle system can trigger an emergency call, compile and send the correct raw Minimum Set of Data (MSD), and establish the voice connection with the PSAP. For next generation operation, the environment also supports IP Multimedia Subsystem and Session Initiation Protocol emulation as part of the call path. Automated conformance test cases can be run against supported regional and international requirements while static or dynamic GNSS scenarios provide controlled location inputs. Engineers can repeat the workflow across network generations and service conditions, review the resulting call and data behavior, and compare the observed sequence with the applicable conformance requirements.

Next Generation eCall Conformance Solution

Perform the test by connecting the in-vehicle system to a controlled cellular-network emulator, GNSS source, and PSAP emulator, then execute the required next generation eCall conformance sequence. The solution provides end-to-end functional and standards-based testing, static and dynamic GNSS simulation, automated eCall test cases, and support for next generation call signaling through IP Multimedia Subsystem and Session Initiation Protocol emulation. Engineers can verify emergency-call triggering, raw MSD transfer, and establishment of the PSAP voice connection without depending on a live mobile network, while optional audio analysis can be added for parallel speech-quality testing.
