Abstract: An apparatus, method and medium thereof to automatically correlate quality information of different layers of a network based on a layered stack model and to perform root cause analysis on the network in accordance with the correlated quality information. The correlated quality information is displayed on a graphical display.

Abstract: A method of displaying quality of service information based on data collected from a system under test. At least one base station related to the collected data is identified and for each time interval a quality of service value is calculated for each of the at least one base station. The quality of service values are compared to at least one defined threshold and a relationship between the quality of service values and the at least one defined threshold is displayed.

Abstract: A test and measurement system having two measurement systems. A first measurement system that monitors communication in a signaling protocol, while a second measurement system that monitors communication in a network protocol. A correlation system correlates the output of the first measurement system with the output of the second measurement system. A graphical user interface generates a display comparing at least one aspect of the output of the first measurement system with at least one aspect of the second measurement system based on the output of the correlation system.

Abstract: A method of displaying quality of service information. The method generally comprises collecting data from a system under test; identifying quality of service parameters; calculating values for quality of service parameters based on the data collected from the system under test; graphing the values on a three dimensional graph having a first axis indicating the parameters, a second axis indicating values of the parameters, and a third axis indicating time.

Abstract: A method of capturing data across interfaces of multiple radio network controllers, distributing the captured data for correlation on a call basis and then correlating and displaying all the captured data corresponding to each of the multiple radio network controllers. Data is captured across various interfaces of radio network controllers in a cellular network via a plurality of distributed network analyzers. Radio network controller events are identified in the captured data according to cell calls for each radio network controller according to analysis by signaling analyzers. The identified events from each signaling analyzer corresponding to captured data for each radio network controller is remotely analyzed and correlated together across the multiple radio network controllers. The correlated events are then displayed on a user interface to permit easy and quick monitoring of the radio network controllers simultaneously.

Abstract: A graphical user interface provides a link to network related measurements by network analysis devices, to present a test including perceptibly correlated network-related measurements by two or more of the network analysis devices through a selectable graphical display corresponding to the network analysis devices, and a selectable graphical display corresponding to at least one measurement for each selected network analysis device. The test provides a newly added measurement.

Abstract: A distributed testing system including (a) a logical agent; (b) a server communicating with the logical agent; (c) a graphical user interface (GUI) communicating with the server; and (d) a framework. The framework interfaces physical agents to the logical agent, the server and the GUI via plug-ins. The framework also interfaces a plurality of measurements to the server and the GUI via plug-ins. The interfaced physical agents perform the interfaced heterogeneous measurement for a test of a communications network in accordance with control by an end user via the GUI.

Abstract: A system uses a resource manager class to allow each task to identify itself and establish OLE links. After each task starts, it calls the resource manager register object method in order to register itself with the resource manager. After registration the resource manager controls the OLE communication when any other task needs to communicate with the task. The system provides a new data object built upon the variant data structure supplied with the Microsoft foundation class (MFC) library. This new data structure is called a getset variant, and it encapsulates the identification of the sender of the data, an access key, used to control access between tasks, the OLE dispatch pointer necessary to access the receiver of the data, and a domain identifier which is used for communication across multiple computer systems.
