- Page 4 tems™ visuAlizAtioN 7.1 eNterPrise how TEMS viSualizaTion EnTERPRiSE woRkS As illustrated in the figure, the TEMS Visualization Enterprise system consists of two main components, the Server and the Clients. The Server handles the collection, processing, and storage of all data. A powerful data processing engine keeps pace with increasing data vol- umes. TEMS Visualization Enterprise has been designed from the bottom up with 64-bit support and multi-core/CPU in mind. The Clients send queries down to the Server, collect the results, and depict them visually. Users install the Client software locally on their own machines with no need for any other remote access software. The separation of the data into Primary and Analysis Databases is a crucial part of TEMS Visualization Enterprise. This separation of data allows users to perform troubleshooting and optimization tasks based on data collected over long time periods, which gives more confidence to decision making.
- Page 5 tems™ visuAlizAtioN 7.1 eNterPrise Main fEaTuRES Automated Network Diagnostics Many of the reasons behind performance degradation are basic issues. Congestion can push traffic to non-optimal cells, installation problems can cause swapped feeders or overshooting cells, real-life coverage can differ from predictions, and equipment can fail. The Capacity Diagnostics and RF Diagnostics features highlight cells suffering from these basic issues and try to identify the root causes. Capacity Diagnostics allow cells with resource issues to be quickly identified. Peak usage statistics for a number of key resource types are calculated. Cells with issues can then be investigated in detail with charts showing, in high resolution, the usage of resources such as channel elements , power, and active HS users.
- Page 6 tems™ visuAlizAtioN 7.1 eNterPrise Optimization Decision Support Intra-frequency Neighbor Optimization makes it possible to easily verify the neighbor plan and find both missing neighbors and non-utilized existing neighbors in a WCDMA network. In WCDMA, an accurate neighbor plan is crucial for network performance. Missing neighbor statistics, as re- ported by actual users, existing neighbor usage, and pilot pollution statistics are presented. In TEMS Visualization 7.1 Enterprise, new per-IMSI statistics allow classification of missing neighbors as UE or network issues. This in- formation is linked to the map view for easy analysis. Changes can be made and saved to a BulkCM format file for import into the OSS-RC. Coverage Area Optimization allows overshooting cells to be quickly identified and down-tilts adjusted. An algorithm calculates an overshooting distance for each cell. During processing, statistics are calculated on the number of overshooting calls and the number of calls established in poor quality. Detailed investigation of the calls established in each distance band and the quality of those calls can also be performed in charts and on the map. Detailed Investigations Exception Analysis summarizes all the GPEH messages recorded for the ...
- Page 7 tems™ visuAlizAtioN 7.1 eNterPrise GeNerAl FeAtures ▪ TEMS Visualization Enterprise can take in the BulkCM format directly from the Ericsson OSS-RC and store the required information in the Project database. This includes neighbor cell relations and selection priorities and other cell parameters required for the features. ▪ Any missing information – such as latitude, longitude and antenna direction, and beamwidth – can be taken from a reference file. ▪ The time duration of data to be analyzed can be selected independently for each feature. ▪ TEMS Visualization includes the most widely used map engine in the world, MapInfo’s MapExtreme ® . This makes it possible to reuse all the maps currently used in TEMS Investigation and MapInfo. ™ ▪ The functionality in the Map View includes thematic mapping display from all of the advanced TEMS Visualization Enterprise features. ▪ TEMS Visualization Enterprise makes it easy to differentiate on the map cells between different carriers (UARFCN) at the same site location. Separate display filters are automatically created. ▪ TEMS Visualization uses the Microsoft ® SQL Server 2008 Enterprise database solution.

- Page 8 A revolutioNAry solutioN GPEH is an extremely powerful source of data, collected in the Ericsson RNC, which records event data for large volumes of user traffic more cost- effectively and in more detail than is possible using passive probes. TEMS Visualization Enterprise adds value by taking this data and automatically processing, analyzing, and highlighting network performance issues for action by the network optimization engineer. Detailed investigation down to individual call data is also possible when required. All this can be done without users ever having to leave their desks. TEMS Visualization Enterprise is ideal for both troubleshooting of network problems on a cell-by-cell basis and for regional optimization. TEMS Visualization Enterprise gives operators the information they need to get the optimal performance from their network in the most efficient manner possible.
