COMPRION Worldwide First to Offer Validated GCF WI-508-NR Test Cases

COMPRION is the first test provider worldwide to offer WI-508 NR test cases validated at GCF meeting CAG#63.

Leading test expert COMPRION has submitted several test cases on COMPRION SIMfony MT8000A for 5G NR USIM mobile phone conformance testing according to GCF WI-508-NR for validation. These test cases include all applicable CT6#100e Change Requests which have now been published in the latest version v15.8.0 of3GPP TS 31.121. The COMPRION solution is listed as test platform TP226 by the Global Certification Forum (GCF) and PTCRB and was developed in close cooperation with Anritsu, the worldwide renowned provider of test and measurement solutions.


Approval of the initial test case validations was received at the GCF meeting CAG#63 which took place July 7-10. Industry experts will be pleased to hear that even more test case validations will be submitted for RFT 508 at the PTCRB Validation Group (PVG) meeting in mid-August.

Udo Willenbrink, Product Manager at COMPRION, comments,“The validation of these test cases at GCF is an important step towards the activation of WI-508-NR. The excellent cooperation with Anritsu enables us to be the first to offer a comprehensive 5G NR USIM/USAT conformance test solution to device manufacturers worldwide".

Kevin Ingrams, Marketing Director at ANRITSU, adds, “These validations represent the latest milestone in a longstanding and successful collaboration between COMPRION and ANRITSU, delivering a first to market solution enabling 5G device manufacturers to start USIM/USAT conformance testing of their commercial terminals”.

COMPRION SIMfony MT8000A consists of the Anritsu 5G Base Station Simulator MT8000A and the COMPRION (U)SIM Simulator UT³ Platform for 5G NR USIM/USAT conformance testing. The solution is also available with COMPRION’s Prove 2 pre-conformance test tool.

UT³ Platform is the heart of the COMPRION terminal test solution and is validated as a platform for conformance testing at GCF, PTCRB, EMVCo, and NFC Forum. In addition to conformance testing, it is a fully configurable analog and logical card simulator for testing mobile phones and NFC-enabled devices with focus on contact and contactless smart card interface technologies.

Anritsu MT8000A is a radio communications test station that supports RF measurements and protocol tests for both the sub-6 GHz and the 5G millimeter wave bands. In addition to supporting 4x4 MIMO and 8CA implemented by eMBB (Enhanced Mobile Broadband), it provides a flexible environment for future 5G test requirements, including URLLC (Ultra-Reliable and Low Latency Communications) and mMTC (Massive Machine Type Communications).
