A wireless coexistence test system is described that comprises a wireless communication emulation module, a signal generator and a processor. The wireless communication emulation module is configured to establish an intended wireless communication link to a device under test. The signal generator is configured to generate at least a first unwanted signal and a second unwanted signal. The processor is configured to evaluate the intended wireless communication link with regard to at least one performance indicator. The processor is configured to adjust at least one of a level and a frequency of at least one of the first unwanted signal and the second unwanted signal based upon the outcome of the evaluation. The processor is configured to curve fit a performance degradation limit based upon at least one of the first unwanted signal, the second unwanted signal and the outcome of the evaluation. Further, a method and a computer program for testing wireless coexistence are described.

In an example, a plurality of previously submitted confidential data values of a first confidential data type retrieved for a slice having one or more attributes. For a confidential data type, one or more submitted confidential data values of the confidential data type from the slice that are considered outliers based on an external data set or internal data set. A confidence score is calculated by multiplying a support score for the confidential data type in the slice by a non-outlier score for the confidential data type in the slice, the support score being equal to n′/(n′+c), where c is a smoothing constant and n′ is the number of non-excluded submitted confidential data values of the confidential data type in the slice and the non-outlier score being equal to n′/n, where n is the total number of non-null submitted confidential data value of the confidential data type in the slice.

A system (10) for testing security of a device under test (11) is provided. Said system (10) comprises a network simulation unit (12) comprising at least two Internet Protocol interfaces (13, 14) communicating with a database (15) via Internet and with the device under test (11), an Internet Protocol data monitoring unit (16), and a non Internet Protocol data monitoring unit (17). In this context, the Internet Protocol data monitoring unit (16) and the non Internet Protocol data monitoring unit (17) monitor communication with respect to the network simulation unit (12) in parallel. Additionally, the system (10) comprises an analyzing unit (18) for analyzing communication security on the basis of results of Internet Protocol and non Internet Protocol monitoring and for comparing the result of said analysis with at least one threat pattern from a threat pattern database (19) especially in the internet.

The present invention relates to a method and a test apparatus for testing a mobile radio supported emergency call system, in particular a mobile radio supported emergency call system or in a motor vehicle. The invention uses an SMS feature of mobile telephones, emergency call system, such as a motor-vehicle emergency call system for testing a telematics unit of the emergency call system. To test a SMS-back command is generated which is sent to the to be tested telematics device. This special SMS-back command prompts to be tested telematics unit to return, bypassing the emergency center the requested answer directly to the sending tester. It is thus prevented in a very elegant way that the tested telematics device sends the requested test information undesirably to an emergency call center.

PROBLEM TO BE SOLVED: To provide a method and test device that test a mobile radio communication support type emergency notification system.SOLUTION: The present invention relates to a method and test device that test a mobile radio communication type emergency notification system, and more specifically relates to a mobile radio communication type emergency notification system loaded on vehicles. The present invention uses the mobile radio communication support type emergency notification system, for example, an SMS function of a vehicle emergency notification system for testing a telematics device of the emergency notification system. For testing, an SMS return command is generated, and the command is transmitted to the telematics device to be tested. The special SMS return command is configured to request the telematics device to be tested to detour an emergency call center and directly return a required responce to the transmission test device. Thereby, a quite sophisticated method prevents an undesirable situation in which the telematics device to be tested transmits requested test information to the emergency call center.SELECTED DRAWING: Figure 4
