Rohde & Schwarz now offers the first validated IMS conformance test cases for 5G NR that can be employed for certification testing according to PTCRB. This accomplishment paves the way for 5G IMS conformance testing.


To guarantee interoperability in various mobile networks, cellular devices must be certified by test labs accredited by GCF or PTCRB. This certification is mandatory for any mobile devices to be affirmed by network operators. Part of this certification are tests for IMS.


The company gives a comprehensive solution for conformance testing based on the R&S CMW500 protocol conformance tester. In connection with the R&S CMX500 radio communication tester, all test systems can be upgraded for 5G NR. Software option R&S CMX-KC621X adds the validated 5G IMS test cases on the R&S CMX500.
