Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level 2-5 20 pt prepared by Julio VeloEricsson ConfidentialUsing TEMS Investigation2006-05-0214 Using TEMS Investigation Working with Workspaces cont’ 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 MS1. 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 MS2 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. It says MS1 but is linked to MS2. The title on the forms is not updated automatically

First let’s take a look of the Line chart This chart shows bars representing RSCP of pilots on the Active Set and lines showing the RSCP for the pilots of the measured neighbours and detected neighbours. Here is shown bars representing Ec/Io of pilots on the Active Set (1 st green,2 nd blue, 3 rd violet) lines showing the RSCP for the pilots of the measured neighbours (orange) and detected neighbours (red). This one illustrates the Ue TX power (blue), the SIR target (green, not available for Samsung) and SIR value (red). Finally, this chart reports the values of the pilots in the Active Set. It also show the strongest measured neighbours and detected neighbours. Additionally, you can see the speeds and time and for a particular moment of the drive

Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level 2-5 20 pt prepared by Julio VeloEricsson ConfidentialUsing TEMS Investigation2006-05-0220 Using TEMS Investigation Analyzing Logs cont’ Now, let’s review other elements such as Serving/Active Set + Neighbours, Radio Parameters, Events, BLER, and Layer 3 Messages. Service/Active Set form shows SC, Cell Id (if celfile exists), CPICH Ec/No and RSCP. The different colors for Ec/No and RSCP (green good, yellow so- so and red bad) represent visual indicator of the quality. The colors and ranges can be customized. This form shows key information such as Ue TX power, RSSI of the serving cell, Target SIR (upon availability), SIR, RRC state, RAT state and again. On this form, the different events that happened during the drive test are reported. You can click on them in order to get more details about them. The BLER% for the different transport channels is shown on this form Finally, this form provide information about the L3 messages. Again you can click on a message to get more details.

Let’s move the scroll bottom back to the first drop call and analyze it 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 (DXU0057Z). Additionally, in the Serving/Active Cell are specified as AS. You can see that the sector DXU3013Z is out of the Active Set window, that is why is removed later Before the last removal, RSCP was good and Ec/NO was acceptable You can get information about an specific point by clicking on the line chart. All the forms are synchronized.

Notice that the cells in the Active Set do not look like the ideal servers. DXU4325W is closer to the Ue and should be a better server, at least, than DXU3013Z. It looks like DXU3013Y is over shooting.
