Abstract [en]

Developments of new Servers for Over-the-Air SIM file management and SIM Toolkit applications require a comprehensive test procedure to verify their operation. The goal of this Master Thesis has been to improve the existing test procedure and if possible develop a new procedure that could make the tests more efficient.

Measurements showed that the most time consuming parts of the existing procedure were latencies in the GSM network and manual operations.

Two major questions had to be handled if it was possible to fully automate the manual test procedure and if an application that reduced the latencies in GSM network would be efficient. This report indicates that it wasn't worth the effort to introduce such an automated test procedure since the extra workload was not in proportion to the benefits.

In order to improve the performance due to the latencies in the GSM network an application that reduced this latency was implemented. This application made it possible to transfer Short Messages directly to the SIM-card without passing through the GSM network or through the mobile phone. With the new procedure the time for existing test procedure was reduced by as much as 65%.
