Starting using TEMS Using TEMS Investigation The first time that you open TEMS Investigation (TI) you will be using the standard workspace. You will see worksheets with different kind of information such as Overview, Data, Signaling, etc. prepared by Julio Velo Ericsson Confidential 3 Using TEMS Investigation 2006 -05 -02

Basic Information Using TEMS Investigation There is not information because all the forms are linked to MS 1 by default. For this drive the scanner was connected to MS 1. We will change this setting later in the presentation You can see the different available analyzes by click on the different worksheets. The first tab shows an overview of the RF conditions for an determined moment of the drive. prepared by Julio Velo Ericsson Confidential 7 Using TEMS Investigation 2006 -05 -02

Basic Information con’t Using TEMS Investigation On the Signaling worksheet you can review the layer 2 and layer 3 messages, events and mode report. prepared by Julio Velo Ericsson Confidential 9 Using TEMS Investigation 2006 -05 -02

Basic Information con’t Using TEMS Investigation This worksheet shows a map with the name, location and sectors azimuth/horizontal beamwidth for the cells on the network. Layers with streets, clusters and RNCs boundaries are shown as well prepared by Julio Velo Ericsson Confidential 10 Using TEMS Investigation 2006 -05 -02

Basic Information con’t Using TEMS Investigation In this screen is shown the information related to the scanner. You can notice that this worksheet shows more information than the previous one. This is because MS 1 was used for the scanner and all the forms are associated to MS 1 by default. prepared by Julio Velo Ericsson Confidential 11 Using TEMS Investigation 2006 -05 -02

Basic Information con’t Using TEMS Investigation A file with information about the cells on the driven area, such as azimuth, scrambling codes, etc, can be defined in order to simplifier the analysis Finally, on this worksheet you can configure different options for the tool such as command sequence, event definitions and audio indicators. Additionally, you can set the celfile to be used with the drive test logs. prepared by Julio Velo Ericsson Confidential 12 Using TEMS Investigation 2006 -05 -02

Using TEMS Investigation Working with Workspaces § § § As you noticed in the previous slides, it is not easy to do an analysis with the default setting for TEMS. However, TEMS investigation allows the creation/modification of worksheets and workspaces. Each one of the worksheets in TEMS investigation can be customized. Information from the different terminals can be shown in the same worksheet. In the same way, each worksheet can be customized to shown information from a unique MS. More worksheets can be added (up to 10 tabs). Existing worksheets can be deleted as well (not recommended) prepared by Julio Velo Ericsson Confidential 13 Using TEMS Investigation 2006 -05 -02

Working with Workspaces cont’ Using TEMS Investigation It says MS 1 but is linked to MS 2. The title on the forms is not updated automatically One problem that you have noticed on the “Overview” worksheet is that is not showing too much information. That is because all forms are linked to MS 1. That can be changed by doing right click on each form and changing the properties. A different MS can be selected. In this case the MS 2 has been chosen for Active Set form. Please notice that the titles on the forms has not been updated. This applies to the next slides too. prepared by Julio Velo Ericsson Confidential 14 Using TEMS Investigation 2006 -05 -02

Working with Workspaces cont’ Using TEMS Investigation You can also add a new worksheets in order to create a view closer to your preferences. Just right click over any tab and the menu for adding/removing worksheet will appear. prepared by Julio Velo Ericsson Confidential 15 Using TEMS Investigation 2006 -05 -02

Working with Workspaces cont’ Using TEMS Investigation On the new worksheet you can add any form available on the presentation menu. There are five different submenus. GSM and WCDMA refer to information for each on those technologies. Signaling is about L 2, L 3 messages and mode. Positioning includes form related to maps. Finally, Templates is just some forms with non- predefined settings. prepared by Julio Velo Ericsson Confidential 16 Using TEMS Investigation 2006 -05 -02

Working with Workspaces cont’ Using TEMS Investigation You can different forms to a worksheet. In this case we are going to add forms related to Voice calls. We added the serving/active set. The mobile needs to be changed to MS 2. We are selecting MS 2 because voice call was recollected using that MS prepared by Julio Velo Ericsson Confidential 17 Using TEMS Investigation 2006 -05 -02

Working with Workspaces cont’ Using TEMS Investigation This was done by using forms from WCDMA and Positioning submenus. Each form has been linked to MS 2. The line chart was changed to include Ec/No information of the second chart instead of GSM info. The map was customized too. Finally, the workspace was saved by clicking on FileSave Workspace as… prepared by Julio Velo Ericsson Confidential 18 Using TEMS Investigation 2006 -05 -02

Additionally, you can see the speeds and time and for a particular moment of the drive Before analyze the logs, let’s discuss the main elements that we can use for the analysis of the log using TEMS investigation. First let’s take a look of the Line chart prepared by Julio Velo Ericsson Confidential 19 Using TEMS Investigation 2006 -05 -02

Analyzing Logs cont’ Using TEMS Investigation You can replay the log and observe the different charts, messages, measurements and the map in order to make your analysis… prepared by Julio Velo Ericsson Confidential 21 Using TEMS Investigation 2006 -05 -02

Analyzing Logs cont’ Using TEMS Investigation Before the last removal, RSCP was good and Ec/NO was acceptable The cells in the active set are indicated by blue lines that go from the cell to the selected point. The service sector is painted on green (DXU 0057 Z). Additionally, in the Serving/Active Cell are specified as AS. You can see that the sector DXU 3013 Z is out of the Active Set window, that is why on is removed control the later You can get information about an specific point by clicking on the line chart.

Analyzing Logs cont’ Using TEMS Investigation You can expand the map to see more details of the drop call. Notice that the cells in the Active Set do not look like the ideal servers. DXU 4325 W is closer to the Ue and should be a better server, at least, than DXU 3013 Z. It looks like DXU 3013 Y is over shooting. prepared by Julio Velo Ericsson Confidential 23 Using TEMS Investigation 2006 -05 -02

BLER is high too. The call is dropped because interference. prepared by Julio Velo Ericsson Confidential 24 Using TEMS Investigation 2006 -05 -02
