Advanced options dialog box

Select the number of rows you want displayed on the Data view, such as the CDR data tab and Sector data tab, which is located at the bottom of the ESPA analysis center screen. The default value is 20 rows and the maximum value is 500 rows. This setting does affect the performance of the ESPA analysis center due to browser limitations. If you are using Google Chrome then the ESPA analysis center performance is slower when you increase the number of rows. For optimal performance it is recommended you set a value between 20 and 50 rows.

Select if you want to include data calls, including some Timing Advance and RTT records, in your analysis. By default this is selected as T-Mobile timing advance records often classify some of their calls as data and if this was not selected then the CDR data tab would not include these useful calls. However, typically an analysis for most CDR file types is done using only voice and SMS calls and not data calls. This is because data calls may not provide accurate location information. If you select to include data calls they are displayed on the CDR data tab using an orange row.

NOTE: If you change this setting the data is refreshed automatically.

Select if you want to exclude terminating cells from automatically being selected on the map and Sector data tab when a call is selected where the originating and terminating towers are different. Also, when this is selected, the Usage column on the Sector data tab does not include the terminating calls in its count.

This setting is selected by default as it is more common to only view the originating sectors and it is easier to see these when the terminating sectors are automatically excluded.

NOTE: If you change this setting the data is refreshed automatically.

Select if you want the Real time smart-track dialog box to display immediately when new live ping data arrives for the case. If this setting is not selected then you are only notified of the new ping data when you click Refresh or Refresh data or perform any other change on the ESPA analysis center screen that causes the screen to refresh.

Select if you want to stop the warning messages from displaying on the map. Normally you will want these to display, however you may want to disable them when you are replaying narratives or taking screen captures of the map.

Select if you do not want to display the public record details on the map by default. This is useful if you prefer to validate the record before displaying it. It is also useful if there are lots of records, as having them all display by default can make the map cluttered.

Select if you do not want the surrounding towers displayed by default. This helps improve the performance when you initially load a case. Surrounding towers can also be manually displayed in the case after it has loaded.

Select if you want to plot the surrounding cell towers from the spatial area and then choose the range in miles. This plots surrounding cell towers from the spatial area with the initial and last information within the range of the time period.

Select the range to be used in Use spatial surrounding towers. The default distance is 10 miles, however you can select a range from 5 miles to 50 miles in 5 mile steps.

Select only if you need to edit the default portrait print width. This setting is used when you are printing a map from the ESPA analysis center screen. For further information refer to Printing the map view.

Select only if you need to edit the default portrait print height. This setting is used when you are printing a map from the ESPA analysis center screen. For further information refer to Printing the map view.

Select only if you need to edit the default landscape print width. This setting is used when you are printing a map from the ESPA analysis center screen. For further information refer to Printing the map view.

Select only if you need to edit the default landscape print height. This setting is used when you are printing a map from the ESPA analysis center screen. For further information refer to Printing the map view.

Set the time interval between the changing of the records on the replay feature. The replay feature is available on the CDR data, Timeline and HO data tabs. For further information refer to Replay and Replaying movements on a tab.

By default this is selected which means the map location and zoom remains the same as you have them currently selected on the map throughout the replay. This is the normal setting, however if you want OSS-ESPA to determine the zoom setting you must clear this setting.

Select if you want to add animation to the replay where the screen zooms in and out when it changes location.

If this setting is:

• not selected, then all the sectors are displayed and stepped through and highlighted, with a black outline, one at a time on the map.

• selected then only one sector is displayed at a time and it is highlighted with a black outline on the map.

Click to apply any changes you have made. The dialog box closes automatically.

The Target summary view can display a lot of data, therefore it is important to load only the data that you are interested in which helps improve the performance of the ESPA analysis center. If you are not using the Target summary view then you should ensure that none of the options are selected.

RTT, Call location group and HO location group are the outputs generated from Include RTT call locations in location analyses and Include HO in location analyses.

Person device at location and Common-location-time are the outputs from the Call analyses tab's Person's device at location and Common location-time.

The remaining record options are those from the uploaded case files.

These settings determine which call analyses are automatically run each time you click Refresh on the Input and settings view. These are the analyses that are displayed on the Call analyses tab. To optimize the performance of the ESPA analysis center it is recommended that you only select the analyses that you are planning to use.

Click to apply any changes you have made. The dialog box closes automatically. Note, any changes to the settings on this tab require you to click Refresh or Refresh data to update the results displayed in the analyses.

Select to display the estimated call location, RTT arc and handover data on the ESPA analysis center screen. When this setting is selected:

• Call loc zoom, Call loc and Conf columns are displayed on the CDR data tab if a phone number is selected that has a CDR file uploaded that contains estimated call locations. A call locations map layer is also displayed.
• An RTT data tab is displayed at the bottom-right of the ESPA analysis center screen if a phone number is selected that has an RTT CDR file uploaded. An RTT map layer is also displayed.
• An HO data tab is displayed at the bottom-right of the ESPA analysis center screen if a phone number is selected that has a CDR file uploaded that contains handovers. A handovers map layer is also displayed.

In most situations you would have this setting selected, however you may want to unselect it you are not currently using the data and the case contains a large amount of advanced CDR data that is slowing down the performance of the ESPA analysis center.

Select to display the map layers for the RTT arcs and the handover sectors. These layers are only available if a phone number is selected that has a CDR file uploaded that contains these features.

Use to set the default depth of the RTT arcs when they are displayed on the map. You can either set to display:

• Custom: using a custom default value and enter the value in meters and then select the units you want used. Typically you will not change this setting, however it may be useful to set it differently if you are trying to identify possible locations in conjunction with other RTT arcs and estimated call locations.

  

• Per technology: based on the depth defined by their technology, that is:

  • LTE: 78.07 m, which equates to an OSS-ESPA setting of 39.035 m. Therefore if you wanted to replicate the technology using the Custom setting you should enter this later value.

  • CDMA: 244 m, which equates to an OSS-ESPA setting of 122 m.

  • GSM: 550 m, which equates to an OSS-ESPA setting of 225 m.

  • UMTS: 234 m, which equates to an OSS-ESPA setting of 117 m.

  The Per technology option is used by default.

  

• Multipath: If you want to know the theoretical minimum distance for the timing advance use this setting as it considers multipath scenarios. The RTT arc can then be displayed on the map using different methods. Which you select is dependent on your organization's preferences. In each instance the maximum displayed distance is the same value; it is the distance + technology depth. The minimum distance however changes with each setting. When set to:

  • 0: the minimum distance = distance. This is the default.

    

  • -1x: the minimum distance = distance - (1 x technology depth).

    

  • -2x: the minimum distance = distance - (2 x technology depth).

    

  • Tower: displays as a pie shape with no minimum distance.

    

If you change this value when you have RTT arcs already displayed on the map they are all automatically updated to the new value unless you have set an individual arc property. An individual arc property is set by right-clicking the arc and setting a value on the RTT arc properties dialog box.

Select to display the map layer for the estimated call locations and to display the Call loc zoom, Call loc and Conf columns on the CDR data tab. This map layer is only available if a phone number is selected that has a CDR uploaded that contains estimated call locations, for example ATT Nelos, Verizon RTT and Tmobile True Call. This allows you to view the call's estimated location.

Use these settings to select how the estimated call locations are displayed on the map by default. These settings are only applicable if the CDR file does not specify the confidence level as an exact distance but instead provides low, medium, high and unknown.

Use Radius to enter the value and then select the units you want to use. This radius setting applies to the radius of the low, medium and high estimated call locations. If you change this value when you have estimated call locations already displayed on the map they are all automatically updated to the new value unless you have set an individual call location property. An individual call location property is set by right-clicking the call location on the map, selecting Call location properties... and setting a value on the Call location properties dialog box.

Use Low, Medium, High and Unknown to select the color you want to identify the confidence level of the estimated call locations on the map. These color settings apply only to the low, medium and high estimated call locations, and not those which provide an exact distance.

Typically you will not change these settings, however it may be useful to set the radius higher than the default if you are zoomed-out of the map and you want to make the call locations more visible.

Use the slider to change the default transparency level used to display the RTT arcs and estimated call locations on the map. Reducing the transparency level is useful if you have multiple highlighted items on the map overlapping each other as it makes it easier to read the underlying map layers and street names.

Note, you can also change the transparency level on an individual basis. For further information refer to either How to change an individual RTT arc's properties or How to change the transparency level of an individual estimated call location. Any RTT arcs or call locations which you have set an individual transparency level on are displayed with a combination of this default transparency level and the individual level. For example if the default setting is set to 50% and the individual setting is set to 50% the overall transparency is displayed as 25%.
