The solution also allows for rapid switching between the two.
The solution is based on Anritsu’s MD8475x base station simulator platform and Thales’ On-Demand Subscription Manager (OSM). It was designed to allow Groupe PSA to conduct a full laboratory test of vehicle with the eSIM integrated into a car’s Telematics Control Unit (TCU).
The car’s eSIM has a profile that allows it to connect to the mobile operator’s network. Until now, only one environment, live or laboratory, could be used in the validation and in the verification test of the vehicle. The new solution allows the eSIM to be switched easily to the laboratory profile. This lets the test team control the simulated network environment as well as the measurements.
Thales OSM switches the profiles over the air at the press of a button. The integration process demonstrated the the change from live to test profile and back again. Initially connected to the live Mobile Network Operator (MNO), the eSIM switched its connectivity to the test radio network from the base station simulator.
Previous methods of swapping profiles included physically desoldering the embedded SIM and replacing with another, or using commands in the TCU, which can be complicated and could lead to undesired changes in TCU firmware.
Martin Varga, EMEA Wireless and Custom Solution Team Leader at Anritsu says: “Working with our partners, the integration of this unique new solution shows that Anritsu has the ability to support a wide range of demanding test environments. By speeding up the testing of vehicles with embedded SIM cards and giving testers complete control of the test regime, it will bring immense benefits to any industry where this technology plays a leading role.”
Cyril Vialleton Architecture Network Security for Connected Car at Groupe PSA says: ‘’Today this technology brings many advantages to Groupe PSA, such as great flexibility for the teams in charge of current and future telematics gateway development of our vehicles. It also allows validation of the eSIM use cases – the OTA MNO migration campaigns for our connected services international development, for example, and enable simplified homologation process approvals for emergency call (eCall) of our vehicles.’’
Christine Caviglioli VP Automotive at Thales says: “With more than 240 connectivity platforms already deployed, Thales has proven expertise in eSIM technology and related subscription management services. Our partnership with PSA and Anritsu demonstrates how to swap connectivity provider for vehicles in a laboratory environment. Together we are building trust in the safety of connected cars”
