Abstract:
Dispatch communication testing may be automated by actuating an electrically-controlled switch coupled to an initiating dispatch device to automatically generate dispatch test events. In one embodiment, user-defined test parameters may be used to determine exactly when the switch is to be actuated. The resulting test events may then be recorded and compared to corresponding recognized dispatch events, where the recognized dispatch events are those dispatch activities that were actually carried out by either the initiating dispatch device or a target dispatch device. One or more performance characteristic for the initiating dispatch device and/or the dispatch communication network may then be determined based on a result of the comparison.
System And Method For Automating Network Device Operability Testing
Network device operability testing is performed by defining a universe of possible device states as a combination of network coverages, available network services and possible subscriber features. In one embodiment, each individual combination of network coverage, for a particular service and feature collectively defines a particular device state for operability testing purposes. In one embodiment, test point data may be generated, where each test point corresponds to the device's operability for a particular device state. In another embodiment, state transitions and test point data may be represented as a node-based device state tree, which may navigated for pinpointing the nature and cause of device operability failures.

Abstract:
A method and system for providing repeatable GPS performance testing of a communication device are provided. Navigation data is complied over a drive route. The navigation data is used as an input to a GPS simulator to duplicate in a laboratory setting the GPS signals present at the GPS receiver during a travel along the drive route. Performance data of a baseline unit can be obtained for benchmarking the performance of a communication device being tested. A device under test can also be exposed to simulated GPS signals and to both simulated GPS signals and other radio frequency signals, such as telephone network signals present along the drive route.
Apparatus, System And Method For Testing Of Communication Networks

International Classification:
H04W 24/08 H04L 12/26
Abstract:
A load test system may include a plurality of remote nodes, a network test controller and a command and control path. Each of the remote nodes may be associated with a corresponding remote user terminal of a plurality of user terminals. The command and control path may operably couple the network test controller to the remote nodes via a communication network under test. The network test controller comprises processing circuitry configured to provide command and control of the remote nodes to generate prescribed communication traffic to load the communication network under test, and monitor a status of network traffic.
