Intelligent Call Trace Analysis
iTV is capable of reading call traces such as CTR. It displays the results in an easy format that could be replied similar to drive test replay, allowing engineers to replay calls as if they have driven them. The tool interprets various events like call drops and handovers with their event and cause codes, making it easier for engineers to troubleshoot issues using L3 messages.
The tool also offers triangulation/geocoding of events with reasonable accuracy to pinpoint where trouble spots are. The triangular feature is a powerful tool in GSM networks where events location is not available. A very powerful feature is the ability to correlate any measured events with network elements. For example, it can trace handover events to a specific radio or timeslot, or RxLev/RxQual distribution per radio and timeslot. The results from this tool has helped reduce troubleshooting time and multiple site visits by pin pointing failures to the broken element.
