Publication number: 20240154891Abstract: The present disclosure relates to a method for determining a size of a buffer of a device-under-test, DUT, which is transmitting data. The method comprises the steps of: transmitting a data stream with a transmitting bit rate by means of the DUT, wherein the data stream is loaded into the DUT buffer during said transmission; receiving the data stream with a receiving bit rate at a receiver device; detecting a difference between the transmitting bit rate and the receiving bit rate over time; monitoring a packet loss at the receiver side; detecting a time at which a packet error rate, PER, at the receiver side increases above a threshold based on the monitored packet loss; and calculating a size of the DUT buffer based on a difference between an amount of data transmitted by the DUT and an amount of data received by the receiver device from the start of the transmission until the detected time of the PER increase.Type: ApplicationFiled: November 9, 2022Publication date: May 9, 2024Applicant: Rohde & Schwarz GmbH & Co.

Patent number: 9532246Abstract: 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.Type: GrantFiled: October 4, 2012Date of Patent: December 27, 2016Assignee: Rohde & Schwarz GmbH & Co. KGInventors: Andreas Michl, William Powell

Patent number: 8189490Abstract: A message analysis device serves for the analysis of messages transmitted via service access points on layers of an OSI reference model. The message analysis device comprises a storage device, for storing messages, a selection device, for reading a series of sequential messages and a display device, for the display of at least one first region and one second region. In the first region, a series of messages read by the selection device from the memory device can be displayed as a list. The selection device determines a characteristic feature of messages for at least one service access point, transmitted by the service access point, whereby the curve for the characteristic feature may be displayed on the display device in the second region.Type: GrantFiled: July 28, 2004Date of Patent: May 29, 2012Assignee: Rohde & Schwarz GmbH & Co.

Patent number: 7890567Abstract: A method is disclosed for determining deviations of a modular end-system message, generated in a hierarchically structured end-system of a telecommunications device, from a reference message. A reference message is read, and an end-system message generated in the end-system is read. A message-structure analysis is performed for the reference message and the end-system message. Any deviations of the end-system message from the reference message are determined from the message structure and structural units of the end-system message that deviate from the reference message are output.Type: GrantFiled: February 10, 2004Date of Patent: February 15, 2011Assignee: Rohde & Schwarz GmbH & Co. KGInventor: Andreas Michl

Patent number: 7587519Abstract: A method and device for modifying modular messages transmittable via an electronic transmission system is described in which a message is read using a read devie and the structure of the message is determined. An individual structural unit of the message can be selected, in which the possible modifications and/or functions can be determined, displayed, and selected. The selected modification is verified for validity with regard to the structure of the message, and, if the modification is valid, execution, whereupon a modified, new message is issued.Type: GrantFiled: February 2, 2004Date of Patent: September 8, 2009Assignee: Rohde & Schwarz GmbH & Co.

Patent number: 7272800Abstract: 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.Type: GrantFiled: January 30, 2003Date of Patent: September 18, 2007Assignee: Rohde & Schwarz GmbH & Co.

Publication number: 20070033527Abstract: The invention relates to a method for determining deviations of a modular end-system message, generated in a hierarchically structured end-system of a telecommunications device, from a reference message. Once a reference message has been read, an end-system message that has been generated in the end system is read. A message-structure analysis is carried out both for the reference message and the end-system message. Any deviations of the end-system message from the reference message are determined from the message structure and the structural units (23, 24,24.1<SB>END</SB>, 24.1.1<SB>END</SB>, 28) of the end-system message (17) that deviate from the reference message are output.Type: ApplicationFiled: February 10, 2004Publication date: February 8, 2007Inventor: Andreas Michl
