  • Patent number: 8412180
    Abstract: The invention relates to a method for generating a signal train which can be played back on a tester for testing a mobile radio. First, a given command sequence is analyzed in respect of a signal train generated therefrom by the tester. The signal train which results from the command sequence is checked by comparing it with a standard-compliant signal train. Discrepancies between the standard-compliant signal train and the signal train resulting from the command sequence are detected and the necessary changes to the command sequence to generate a standard-compliant signal train are ascertained. In line with the necessary changes detected, commands or command sequence sections are supplemented and/or replaced. In this way, a command sequence which can be played back is generated and output.

  • Patent number: 8320839
    Abstract: A method for testing a mobile-radio device is provided. The method includes determination of information regarding at least one real mobile-radio network using a measuring device, and additionally and independently using a mobile-radio device. The method further includes analysis of the information, received through the measuring device and through the mobile-radio device, regarding the mobile-radio network using an analysis device, analysis of all signals incoming to and respectively outgoing from the mobile-radio device using an analysis device, conversion of the information into an instruction sequence, and simulation of the real mobile-radio network through the implementation of at least a part of the instruction sequence by the test device.

  • Publication number: 20100173591
    Abstract: A method for testing a mobile radio device in a real test scenario, using a test device in which signal sequences, typical of mobile telephony, of a plurality of base stations are produced. The signal sequence of one base station each is allocated to one of the plurality of send/receive channels of the test device. The signal sequence of at least one of the plurality of base stations is alternatively allocated to at least one of the plurality of send channels of the test device and the signals sent back from the mobile device to be tested are evaluated.

  • Patent number: 7272800
    Abstract: A message analysis device is described including a storage device, display device, and a selection device. The storage device can be used to store messages in a file in chronological order, and the a display device can be used to display at least one first and one second window. One part of the messages, which are chronologically stored in the file, can be displayed in the first window. The selection device can be used to select at least one message to be displayed in the second window, corresponding to a parent and/or child generation of a specific message. Accordingly, information can be evaluated from a message header to determine and represent those parent-generation messages that causally triggered a specific message and/or those child-generation messages that are causally determined by the specific message.
