A protocol test device for testing protocol compliance of a wireless device under test comprises a wireless interface for transmitting an outgoing RF signal to the wireless device under test and/or for receiving an incoming RF signal from the wireless device under test, a processing unit for generating messages for the outgoing RF signal based on a predefined protocol and for processing messages in the incoming RF signal based on the predefined protocol, a message log memory for storing the generated messages and the received messages, and a summary message generation unit that generates a summary log message and stores the summary log message in the message log memory, wherein the summary log message comprises information about at least one of the generated messages and/or the received messages and repetitions of the respective generated message and/or the respective received message.

Protocol test device and method for operating a protocol test device

A test unit for testing a plurality of communications devices is provided. The test unit comprises a test case database, which stores a first test case (including a first test case idle time) and a second test case. The second test case is shorter than the first test case idle time. The test unit comprises a signaling unit. The test unit comprises a test case execution manager, which reads from the test case database the first and second test case and controls the signaling unit to perform measurements according to the first test case on the first device under test until a beginning of the first test case idle time, and controls the signaling unit to perform measurements according to the second test case on the second device under test during the first test case idle time.

Test unit and test method for efficient testing during long idle periods

A mobile communication test device for testing a mobile user equipment comprises a number of transmit-receive units with a signal generator, wherein the signal generator of at least one transmit-receive unit generates test signals, which rep-resent at least two different communication partners of the mobile user equipment, a number of test interfaces, which connect the transmit-receive units with the mobile user equipment and transmit the test signals to the mobile user equipment, and a test processor, which analyzes the reaction of the mobile user equipment to the transmitted test signals based on a predefined test specification.

Mobile communication test device and a corresponding method

A Multiple Input Multiple Output, MIMO, baseband apparatus with a baseband signal interface adapted to transmit or receive baseband signals comprising data mapped by a mapping unit of said baseband apparatus to a number, N, of MIMO layers which are coupled by a MIMO layer coupling unit of said baseband apparatus to different remote radio heads connected to said baseband apparatus.

Multiple input multiple output, MIMO, baseband apparatus

The method is used for detection and/or removal of errors in transmission systems which comprise a transmitter unit and at least one receiver unit. The transmitter unit transmits to the receiver unit on a semi-persistent transmission resource which provides an adjustable frequency range and an adjustable time period. Furthermore, the self-repeating, semi-persistent transmission resource repeating with the period Tis rigidly assigned to the receiver unit. Following this, at least one but not all of the HARQ process numbers available for the self-repeating, semi-persistent transmission resource are reserved for the latter.

Dynamic HARQ-id reservation

An automated evaluation of test logs for the testing of telecommunications equipment includes a probabilistic model that links possible events in a test log with possible causes for the event. Probability values for possible causes are calculated from the probabilistic model and a search result, and a reference to a possible cause is provided in an output based upon the calculated probability values.

Automated evaluation of test logs

A method for automatically configuring a tester to perform functionality tests between a mobile station under test and a tester simulating a mobile communication system. The method includes receiving an identification information according to the type of the mobile station under test in the tester, retrieving characteristic parameters of the identified type of the mobile station under test from a device database by the tester, and selecting a subset of test cases which is applicable to the characteristic parameters of the identified mobile station under test from a test case database by the tester and offering the subset of test cases to generate a test program by applying one or more test cases of the selected subset.
