TEMS ™ DISCOVERY NETWORK – BRIDGING THE OPTIMIZATION GAP For mobile operators that are serious about delivering ubiquitous quality and availability, traditional network performance management tools simply aren’t enough. To home in on problems that were impossible to pinpoint before (those in difficult-to-drive-test spots or related to individual subscriber or phone model issues), operators must complement their network performance management and drive-testing tools with advanced network visualization and optimization capabilities. Breakthrough network optimization tools such as TEMS Discovery Network (previously known as TEMS Visualization Professional) use subscriber- centric event-based data collected at the OSS to bridge the critical gap between performance management systems and drive testing. While performance management tools provide high-level key performance indicators (KPIs) from counter data, and drive-testing tools capture thin slices of network traffic, TEMS Discovery Network derives detailed information from large volumes of live network traffic. TEMS Discovery Network is a desktop based solution for detailed drilldown and analysis of subscriber call trace data. TEMS Discovery Network can also integrate with TEMS Discovery Enterprise to provide the troubleshooting aspect for the platform solution. (TEMS Discovery Enterprise is Ascom Network Testing’s client-server-based solution for analysis of large volumes of data from devices, network elements and applications). RADIO NETWORK OPTIMIZATION Built-in advanced algorithms enable efficient radio network optimization. Examples for WCDMA in- clude: neighbor relation optimization including inter- frequency and IRAT, pilot pollution detection and geolocation, RF diagnostics using DL and UL radio measurements and identification of overshooting cells. IN-DEPTH TROUBLESHOOTING With more details than counters and more coverage than drive testing, previously hidden issues in the radio network can be identified. Performance issues can be isolated to the cell, phone model or even in- dividual subscriber level. From high-level statistical analysis, engineers can directly drill down into indi- vidual call-by-call analysis. OPERATIONAL EFFECTIVENESS By utilizing subscriber-centric call trace data collected in the radio networks nodes, TEMS Discovery Network empowers operators to improve network quality and operational efficiency – with virtually no additional costs for data collection and post processing.
