METHOD AND TEST DEVICE FOR TESTING AN EMERGENCY CALL SYSTEM SUPPORTED BY MOBILE TELEPHONY

摘要

The present invention relates to a method and a test device for testing a mobile radio-based emergency call system, in particular a mobile radio-based emergency call system for or in a motor vehicle. The invention uses an SMS function of a mobile radio-based emergency call system, such as a motor vehicle emergency call system, for testing a telematics device of the emergency call system. For testing, an SMS return command is generated, which is sent to the telematics device to be tested. This special SMS return command requests the telematics device to be tested to return the requested response directly to the sending test device, bypassing the emergency call center. It is thus prevented in a very elegant way that the telematics device to be tested sends the requested test information undesirably to an emergency call center.
