Rohde & Schwarz CMW-KC504 IMS emergency call over EPS/EUTRA software

Rohde & Schwarz has reached a milestone in the introduction of voice over LTE telephony for the IP multimedia subsystem (IMS). The T&M specialist has verified the world's first test cases for IMS emergency calls over EPS/EUTRA in compliance with GCF Work Item 154.

All mobile phones and smartphones must be able to place emergency calls, both in their home network and in other networks - even without a SIM card. The correct signalling of an emergency call is crucial in an emergency. In cooperation with leading chipset makers, Rohde & Schwarz is claimed to be the first T&M manufacturer to verify test cases defined in GCF Work Item 154 for IMS Emergency Call over EPS/EUTRA. The R&S CMW500 multi-RAT protocol tester was used to test the RRC connection set-up for an emergency call and the IMS emergency call registration. This is a key step in the transition towards pure LTE networks. In the past, placing emergency voice calls on LTE networks was especially challenging for network operators, chipset makers and consumer electronics manufacturers.

The R&S CMW-KC504 IMS emergency call over EPS/EUTRA is a software option for the R&S CMW500 multi-RAT protocol tester.
