摘要

A testing device (1) is for use in a test system for testing of transmission processes in a mobile radio network. The test device (1) has a mobile telephone (2), which is designed in such a way that it with a subscriber identification module (sim) can communicate. Furthermore, the test device (1) a the mobile telephone (2) locally associated sim - simulation computer (4) for providing a sim - simulation which has a central, physical sim - cards (9) managing sim - a server computer (7) is connectable. - The sim simulation computer (4) comprises a designed for a time-critical transmission answer to reset - (atr -) generator (5) for generating a with a part of a complete atr - signal matching atr - signal (8). The test device has a in comparison to the sim - simulation computer (4) is less efficient computer for less time-critical transmission of a atr - residual signal.
