Keysight Technologies has gained approval from the Global Certification Forum (GCF) for a conformance test case that enables chipset vendors to verify internet protocol (IP) multimedia subsystem (IMS) based eCall functionality. With this technology, also known as LTE and Interworking with eCall in IMS (EIEI), Keysight aims to advance in-vehicle emergency call capabilities over 4G LTE networks. 

EIEI enables vendors of telematics units to verify IMS-based eCall functionality in compliance to specifications set by The 3rd Generation Partnership standards group. The eCall connection uses voice over LTE to establish a manual or automatic voice call between emergency services and the occupants involved in the incident.
