Keysight First to Gain GCF Approval for Test Case Verifying IMS Based eCall Functionality

Advances in-vehicle emergency call (eCall) capabilities over LTE networks

Keysight Technologies, Inc., a leading technology company that delivers advanced design and validation solutions to help accelerate innovation to connect and secure the world, announced the company is first to gain 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, advancing in-vehicle emergency call capabilities over 4G long term evolution (LTE) networks.

“Keysight plays a key role in helping automobile vendors meet evolving safety requirements by enabling telematics system makers to quickly and easily adopt the latest digital and connectivity platforms.”

Confirmed by the GCF conformance agreement group in October 2021, Keysight’s achievement is formally referred to as LTE and Interworking with eCall in IMS (EIEI). It enables vendors of telematics units to verify IMS-based eCall functionality in compliance to specifications set by 3GPP, the global standards organization. The eCall connection uses voice over LTE (VoLTE) to establish a manual or automatic voice call between the emergency services and the driver or passenger in the vehicle involved in the incident.

Automotive vendors need access to the latest communications solutions, based on LTE, 5G and cellular vehicle-to-everything (C-V2X), to deliver continuous safety and convenience for drivers, passengers and pedestrians. IMS enables carriers to cost-effectively deliver rich multimedia services including voice over IP (VoIP), videoconferencing and video on demand (VoD) to end-users. The LTE EIEI test case submission to GCF used Keysight’s S8704A Protocol Conformance Toolset, based on the company’s E7515B UXM 5G Wireless Test platform.
