Overview

Interoperability Test Center is used for:

Interoperability testing (smart card/terminal for contact-based and contactless interfaces)
Development/debugging of
- mobile phones/chipsets
- smart cards
- M2M devices
- NFC-enabled devices, contactless terminals/readers and front-ends (CLFs)
- NFC applications
- contactless cards
- RFID tags
Visualization and measurement of analog signals
Combined NFC/SWP/HCI testing
Quality assurance
Simultaneous test and analysis of UICC interfaces (ISO/IEC 7816, SWP/HCI, IC-USB) and contactless (NFC) interfaces
Field testing (mobile usage)

Efficient testing with multi-view screen UI

The Interability Test Center's user interface features a multi-view screen displaying multiple views simultaneously. Monitored data is promptly displayed during sessions for quick analysis. Synchronized views enable efficient testing and analysis of UICC interfaces (ISO/IEC 7816, SWP/HCI, IC-USB) and contactless (NFC) interfaces simultaneously.

Example of analyzing SWP combined with contactless communication

The monitoring session screenshot displays SWP alongside contactless communication. In the Physical Layer view, detailed bit and byte-level data within communication frames are visible for precise analysis, including time markers for precise measurements. The Protocol Layer view showcases exchanges occurring on ISO7816 or SWP/HCI interfaces. Additionally, the Application Layer offers real-time interpretation of commands spanning GSM, 3G, ISIM, CDMA, HCI, Global Platform, EMVCo, USB, SIM Toolkit (U)SAT, and Terminal Profile interpretations.

Troubleshooting with Analog Scope

The Analog Scope function is an additional feature for analyzing and troubleshooting signaling errors. It records and visualizes analog data, providing quick measurements of waveform characteristics with a single mouse click. Additionally, the Analog Scope Viewer allows evaluation of measurement results, including time intervals, to aid troubleshooting and assess IUT performance. Independent of test case execution, it can be used for discrete monitoring sessions. With predefined quick measurements, you gain valuable information on waveform characteristics and receive detailed comments explaining test failures.

Analyzing OTA communication

Mobile Network Operators (MNOs) use over-the-air (OTA) programming as a core mechanism for secure provisioning and (re-)programming of smart cards in the field. In order to protect data integrity as well as subscribers’ privacy, data is transferred in encrypted sessions.

The monitoring session screenshot displays communication of an OTA Update using SCP80/SMS in a Multi IMSI scenario. The execution of the different steps of the remote command which includes read, update and refresh can be followed in detail. As security domains, key profiles, and key sets can be individually specified for the OTA session the data processing allows a decryption of the OTA communication.

Remote Application and File Management (HTTP example)

Remote management of files and applications (over the air) can be analyzed on two layers:

The Remote Management Protocol Layer view displays the RAM/RFM monitoring data in the form of frames and APDUs.
The purpose of the Remote Management Application Layer (APDU) is to translate the (top-level) data provided by the Remote Management Protocol Layer into textual form and to display it. It shows monitored remote APDUs plus additional information.

How to Make OTA Transmissions Readable

Test engineers who want to detect and solve problems in the OTA communication chain face the challenge of understanding the encrypted commands. OTA Remote Management Translator enables the user to view into the complete OTA communication. It decrypts and unwraps the data packages, sets them to the right order of command and response pairs and translates them into a human readable format.
