TEMS DISCOVERY NETWORK BRIDGING THE OPTIMIZATION GAPFor mobile operators that are serious about delivering ubiquitous quality and

availability, traditional network performance management tools simply arent

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 Testings client-server-based solution for analysis of large

volumes of data from devices, network elements and applications).

RADIO NETWORK OPTIMIZATIONBuilt-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 EFFECTIVENESSBy 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.

TEMS DISCOVERY NETWORK 10.0

Features Description

Multidimensional KPI View Quick identification and troubleshooting of poorly per-forming cells, clusters, WCDMA phone models, and individual subscribers. Statistics for accessibility, retainability, mobility, and packet-switched data performance are aggregated from WCDMA GPEH/UETR/Megamon GEO, GSM R-PMO/CTR/MTR, and LTE CellTrace/UE Trace data with direct drilldown to detailed call analysis for problem calls.

Vendors/technologies supported

Ericsson (GSM, WCDMA, and LTE), Huawei (WCDMA) and Nokia Siemens (WCDMA).

Editions TEMS Discovery Network is a desktop version that can be operated on a stand-alone basis and is also included with TEMS Discovery Enterprise, Ascoms enterprise post processing and analytics platform.

Geolocation Strong geolocation and visualization features: Geolocate problem events, follow calls and hand-offs on a map, determine neighbor optimization graphically. Helps engineers know where calls are dropping and provides statistical view of problem areas.

Other GSM Functionality Cell timeslot monitor, estimated positioning, binned maps, task manager, and more.

Troubleshoot holistically across todays multi vendor, multitechnology network environments to uncover problems not detected by drive testing or high-level statistical analysis, resolve those problems rapidly, and optimize network performance and resource utilization.

TEMS DISCOVERY NETWORK ENABlES NETWORK OPERATORS AND SERVICES PROVIDERS TO: Automatically post-process subscriber-centric, event-based data generated by the network infrastructure, so it is ready for use.

Analyze and organize that information, including statistical data, for radio network troubleshooting, optimization, functionality verification, and better

decision making.

Find network coverage and quality problems that were impossible to pinpoint before.

Achieve optimal performance from their networks, allowing them to improve network KPIs and reduce subscriber churn.
