New Features of the Assistant V300R003C01

The Assistant V300R003C01 is developed on the basis of the Assistant V300R003C00 and has the following new features:


Project Configuration Management

KPI selection: Select the KPIs to be analyzed. In addition, you can set thresholds for KPIs. The KPI values that do not meet the KPI thresholds are displayed in red in the KPI analysis results.

The configuration of the preceding information can be imported to the project template or exported as .xml files for future use.

The settings in the project template are effective for all the analysis groups in the project.

After a project is created, perform the following operations in the project template:

Binning setting: Set Binning Type to Distance Binning or No Binning.

Setting of theme parameters: Set the theme thresholds for the theme analysis.

IE selection: Select the IEs to be analyzed.

Setting of filtering conditions: Set the time filtering conditions and IE filtering conditions to obtain the required data.

Site display setting: Set the shape, size, and label for cells and base stations.


Data Import

The data import of the Assistant is largely different from the data import of the Assistant V1 and the data import of the Assistant V2.

On the Assistant V300R003, open the Logfile Manager dialog box, and then select DT logfiles to create an analysis group. After that, right-click the analysis group, and then choose Run Analysis from the shortcut menu to analyze all the DT logfiles of the analysis group (this process takes a long time). Finally, the Assistant displays the analysis results based on the created analysis group (quickly performs further analysis).

Note: Auto Combine in the Logfile Manager dialog box means that the data automatically sliced by the Probe can be automatically combined. In the Assistant V2, DT logfiles are combined by MS ID.


Analysis Group Management

Note: An analysis group is a set of data. You can create an analysis group that contains data of different terminals according to the service requirements. In addition, you can create an analysis group by MS ID, device type, IMSI, or IMEI.

Operation: Right-click the Analysis Group node, and then choose Analysis Group Manager from the shortcut menu. In the Analysis Group Manager dialog box, click Add to create analysis groups and set reports for the analysis groups.Example:

1. To collect the statistics of the KPIs related to different services, group the data of terminals that process various services into one analysis group.

2. To view indicators by service, create analysis groups for different test plans by MS ID. For example, assign one MS ID to the E1820 terminal that processes data services and assign one MS ID to the scanner.


Engineering Parameter Management

Choose Site > WCDMA (or GSM) from the navigation tree on the Project tab page.

Right-click WCDMA or GSM and then choose View Engineering Parameter from the shortcut menu. In the displayed window, click Import the BTS Information icon to import data.

Note:

1. The required fields in the GSM engineering parameters are LAC, CI,

Longitude, Latitude, Azimuth, and BCCHNo. The required fields in the

WCDMA engineering parameters are Cell ID, UARFCN, PSC, Longitude,

Latitude, and Azimuth. Other fields are optional fields. If required fields are not

imported, engineering parameters fail to be imported successfully. If the value of

the required field in a certain row is invalid, the data in this row will be discarded

and is not imported. This does not affect the import of data in other rows. If the

value of the optional field in a certain row is invalid, the data in this row will be

considered as null. This does not affect the import of data in other rows.

2. Before importing engineering parameters, you must check the sheet where the

engineering parameters are present, and then select the corresponding sheet.

3. If the table header in the engineering parameter table in the Assistant is the

same as that in the engineering parameter table to be imported, the fields can be

matched automatically. Otherwise, the fields need to be manually matched.

4. After engineering parameters are imported to the Assistant, the errors occurred

during the import are exported as a .csv file. You can open this file to view the

errors in engineering parameters.


Engineering Parameter Display

Method 1:

Choose Project Setting > Sites Display. On the Sites Display tab page, set Shape, Size, Label Field, and Visible in Report for cells and BTSs. The settings are applicable to all maps involved in the project.

Rendering after Label Field is set to NodeBName+CellID+PSC.

Rendering after Label Field is set to SiteName+BCCH+BSIC in the GSM network

Method 2:

On the engineering parameter layer, click edit Cell Label to set labels for cells. The settings are applicable only to the current map.


Cell Radius Calculation

Procedure:In the GSM Engineering Parameter dialog box or WCDMA Engineering Parameter dialog box, click the Calculate Cell Radius icon to calculate the cell radius. Note that the fields, such as Azimuth, NodeBID, Longitude, and Latitude, are required fields when you calculate the cell radius. If these fields are empty, the cell radius cannot be calculated.The principle for calculating the cell radius is as follows:According to the azimuth and beamwidth of a cell, the Assistant calculates the distance between the cell and other base stations within cell coverage, and then obtains a weighted value that is used as the cell radius. The calculated cell radius is considered as the basis for determining the over coverage problem. Note that the indoor cell does not need to calculate the cell radius, but you must fill the related information in the CellType field in engineering parameters. Otherwise, indoor cells are considered as macro cells by default.

The cell radius is displayed, as shown in the chart in the lower left corner of this slide. You can determine whether to display the cell radius through the layer. The length of a line indicates the radius of a cell. You can double-click a line to modify the cell radius.

Note: Before the theme analysis is performed, cell radius must be calculated.


Viewing Theme Results

Note:The theme analysis involves displaying theme results, displaying the detailed information about the theme results, and displaying the theme results on a map.The preceding chart shows the Theme Result View dialog box. The features of the Theme Result View dialog box are as follows:1. The results of the themes, such as over-coverage rate, are displayed by cell.2. All the theme results displayed in the Theme Result View dialog box can be exported.3. The sorting of theme analysis results are supported. If the analysis results of a theme are sorted, problem cells can be quickly located. After that, you can perform the drilldown analysis. In addition, the filtering query is supported.4. In the theme results shown in the preceding figure, the numerator indicates the number of problem DT points and the denominator indicates the total number of DT points in the serving cell, the division result is the theme result.


Viewing Theme Detailed Information and Related Information

Note:The Theme Detail dialog box is used for displaying the statistical results of cells and the related information of a certain DT point. You can click different tabs to view the detailed information about different themes.1. Chart: indicates the statistical chart based on the distance step. You can set different steps for different themes. The green bar indicates the total number of DT points that server as the serving cell within the corresponding distance range. The red bar indicates the number of problem DT points.2. Statistical Result area: lists the total number of DT points, the number of problem DT points, and the statistical percentage of each theme.3. Synchronous display of neighboring cell parameters: The neighboring cell parameters are displayed synchronously in the Theme Detail dialog box.


Viewing Theme Results on a Map

Click a DT point in the map window shown in the preceding figure. DT points are connected to the active set cells through solid lines, whereas DT points are connected to the monitor set cells or detected set cells through broken lines. In addition, you can view the information about the active set, monitor set, and detected set in the synchronously displayed window. The red circle in the preceding figure indicates the cell coverage and the horizontal beamwidth. The chart in slide 13 is a statistical chart that shows the number of DT points in different steps, including the number of DT points where the over coverage problem occurs and the number of normal DT points.

Note:In the left figure, the DT points in red indicate the DT points where the over coverage problem occurs. The DT points in green indicate the normal DT points, that is, the over coverage problem does not occur. The DT points in gray indicate that this area is not covered by the serving cell. The DT points in red and green indicate the DT points within the coverage of serving cell whose analysis results are drill down.You can view the number of DT points where the over coverage problem occurs and the number of normal DT points based on the legends on the right pane. The legends on the right pane indicate the meanings of DT points in different themes.


WCDMA Over CoverageNote:Over coverage refers to that the coverage areas of certain NodeBs exceed the planned range and incontinuous dominant areas are formed in the coverage areas of other NodeBs. The Assistant calculates the cell radius based on engineering parameters. If a DT point is not within the area specified by the cell radius threshold and the difference between the RSCP of the serving cell and the maximum RSCP of a neighboring cell is lower than the value of the configuration parameter, this DT point is considered as the DT point where the over coverage problem occurs. In addition, the Assistant supports the analysis of data collected by UEs or scanners.

Description of configuration parameters

Alarm Threshold: indicates the over coverage alarm threshold.Over Coverage Rate(%) = Over Coverage Count/Total CountIf the value of Over Coverage Rate is higher than Alarm Threshold, the analysis results are displayed in red in the Theme Result View window after the theme analysis is performed.

Coverage Extended Radius: indicates the cell radius extended parameter factor.Cell coverage distance threshold = Cell radius x Coverage Extended Radius

RSCP Offset: indicates the RSCP offset. When the difference between the maximum RSCP of a DT point and the maximum RSCP of a neighboring cell is lower than RSCP Offset and is higher than the cell coverage distance threshold, this DT point is considered as the DT point where the over coverage problem occurs.

Distance Step: indicates the distance step. Based on the distance step, the Assistant counts the number of DT points where the over coverage problem occurs and the total numbers of DT points.


WCDMA No Serving Cell DominanceNote:No serving cell dominance refers to that no serving cell is available in the coverage area or calls in the serving cell in the coverage area are frequently handed over. In this case, frequent handovers may occur, and therefore the system efficiency is reduced and call drops occur. The Assistant determines the DT points where the problem of no serving cell dominance occurs according to the difference between the RSCP of the serving cell and the RSCP of the neighboring cell (collected by UEs or scanners). If the difference between the RSCP of the serving cell and the RSCP of the neighboring cell is smaller than the specified threshold, the DT points within the coverage area are considered as the DT points where the problem of no serving cell dominance occurs. Alternatively, the Assistant determines the problem of no serving cell dominance according to the events related to frequent handovers. If the number of handover events within the specified time exceeds the related threshold, the DT points measured within the specified time are considered as the DT points where the problem of no serving cell dominance occurs.


Alarm Threshold: indicates the alarm threshold of no serving cell dominance.

Analysis Mode: indicates the analysis mode. The analysis mode is categorized into the analysis based on RSCP and the analysis based on events related to frequent handovers.

Analysis based on RSCP

RSCP Threshold: indicates the RSCP threshold of the serving cell.The RSCP threshold of the distance ranging from 0 to 1 km is -95. The RSCP threshold of the distance more than 1 km is -100.For the distance within 5 km, each 500 m is considered as one segment. The distance over 5 km is considered as one segment. Therefore, the total number of segment within the total distance is 11.

ΔRSCP Threshold: indicates the RSCP difference threshold, that is, the difference threshold between the RSCP of the serving cell and the RSCP of the neighboring cell. If the difference between the RSCP of the serving cell and the RSCP of the neighboring cell is less than ΔRSCP Threshold, the DT point is considered as the DT point where the problem of no serving cell dominance occurs. The default value of ΔRSCP Threshold is 5 dBm.

NB Count Threshold: indicates the number of neighboring cells. The number of neighboring cell that is smaller than or equal to NB Count Threshold is valid.

Analysis based on events related to frequent handovers

Interval Time: indicates the interval between handover events.Cell coverage distance threshold = Cell radius x Interval Time

HO Event Count: indicates the threshold number of handover events. If the total number of 1D events and cell reselection events that occur within Interval Time is the same as HO Event Count, it indicates that frequent handovers occur.

Distance Step: indicates the distance step. Based on the distance step, the Assistant counts the number of DT points where the problem of no serving cell dominance occurs and the total number of DT points.


WCDMA Downlink InterferenceNote:Downlink interference refers to that the interference signals generated by the interference source are on the downlink frequency band in the mobile network. After receiving interference signals, the UE cannot distinguish NodeB signals from interference signals, and therefore the communication between the UE and the NodeB is disrupted. As a result, call drops occur. Based on

the parsed data of UEs or scanners, the Assistant determines the Ec/Io and RSCP of the serving cell. If the receive level is high and the service of quality (QoS) is low, it is considered that the downlink interference problem occurs.


Alarm Threshold: indicates the downlink interference alarm threshold.DL Interference Rate (%) = DL Interference Count/Total CountIf DL Interference Rate is higher than Alarm Threshold, the analysis results are displayed in red in the Theme Result View window after the theme analysis is performed.

RSCP Threshold[0,500*N): indicates the RSCP threshold of the serving cell within the distance ranging from 0 to 500*N. If the RSCP of the DT point is higher than RSCP Threshold[0,500*N), it indicates that the RSCP of the DT point is good.

Ec/Io Threshold: indicates the signal quality threshold. If the Ec/Io of the DT point is higher than Ec/Io Threshold, it indicates that the receive quality of the DT point is good.

Distance Step: indicates the distance step. Based on the distance step, the Assistant counts the number of DT points where the downlink interference problem occurs and the total number of DT points within the coverage area.


WCDMA Intra-Frequency/Inter-Frequency Neighboring Cell Analysis

Note:The Assistant supports the analysis of missing intra-frequency neighboring cells and analysis of missing inter-frequency neighboring cells. The Assistant automatically determines the mapping between the serving cell of the DT point and neighboring cells of the DT point, and compares the determined result with the imported neighboring cell data to filter out missing neighboring cells. The data collected by scanners can be used for the analysis of missing intra-frequency neighboring cells and the analysis of missing inter-frequency neighboring cells. Before analysis, import the data of configured neighboring cells.


Analysis of missing intra-frequency neighboring cells

Ec/Io Difference Threshold: indicates the Ec/Io difference threshold. If the difference between the Ec/Io of the serving cell and the Ec/Io of the neighboring cell is lower than Ec/Io Difference Threshold, the decision of missing intra-frequency neighboring cell can be performed. The default value of Ec/Io Difference Threshold is 3 dB.

Analysis of missing inter-frequency neighboring cells

Serving Cell RSCP Threshold: indicates the signal quality threshold. If the RSCP of the serving cell is greater than Serving Cell RSCP Threshold, the decision of missing inter-frequency neighboring cell can be performed. The default value of Serving Cell RSCP Threshold is -105 dBm.

Neighbor Cell RSCP Threshold: indicates the RSCP threshold of inter-frequency neighboring cell. If the RSCP of the inter-frequency neighboring cell is higher than Neighbor Cell RSCP Threshold, further analysis can be performed. The default value of Neighbor Cell RSCP Threshold is -90 dBm.

Neighbor Cell Ec/I0 Threshold: indicates the Ec/Io threshold of the inter-frequency neighboring cell. If the Ec/Io threshold of the inter-frequency neighboring cell is greater than Neighbor Cell Ec/Io Threshold, further analysis can be performed. The default value of Neighbor Cell Ec/Io Threshold is -12 dB. If one of the preceding conditions is met, the measured cell is considered as the missing inter-frequency neighboring cell of the serving cell.


WCDMA Pilot Pollution

Note:Pilot pollution refers to that there are too many strong pilots, but no pilot is strong enough to be the primary pilot at a point. Based on the analysis of DT data collected by UEs or scanners, the Assistant determines whether the measured cell is the neighboring cell of the serving cell and identifies the DT points where the pilot pollution problem occurs.Formula:The DT points where the pilot pollution problem occurs must meet the following conditions:

Pilot pollution signal of the active set ≥ {NB Cell Count}

Total pilot signal strength ≥ {RSCP Threshold}

Difference between the strongest pilot signal and any other pilot signals <

{RSCP Difference}


RSCP Threshold: indicates the RSCP threshold. The default value is -100.

RSCP Difference: indicates the RSCP difference, that is, the difference between the RSCP of the serving cell and the RSCP of the neighboring cell. The default value is 5 dBm.

NB Cell Count: indicates the threshold of neighboring cell count. The default value is 3. The DT point where the pilot pollution problem occurs can be considered if one of the preceding conditions is met.


GSM Over Coverage

Note:Over coverage is produced when the coverage areas of certain BTSs exceed the planned range. In this case, incontinuous dominant areas are formed in the coverage areas of other BTSs. The Assistant calculates the cell radius based on engineering parameters. If a DT point is not within the area specified by the cell radius threshold, this DT point is considered as the DT point where the over coverage problem occurs.


Alarm Threshold: indicates the over coverage alarm threshold.Over Coverage Rate (%) = Over Coverage Count/Total CountIf Over Coverage Rate is higher than Alarm Threshold, the analysis results are displayed in red in the Theme Result View window after the theme analysis is performed.

Distance Threshold: indicates the extended coefficient of the cell radius. Cell coverage distance threshold = Cell radius x Distance ThresholdThe default value of Distance Threshold is 2.

Ratio of Start Distance: indicates the ratio of the start distance within a distance segment. Start Distance = Cell radius x Ratio of Start Distance

Ratio of End Distance: indicates the ratio of the end distance within a distance segment. End Distance = Cell radius x Ratio of End Distance

Bound Number: indicates the number of distance segments between the start distance and the end distance. Bound Number affects only the statistics in the chart in the Theme Detail window.


GSM Poor Coverage

Note:Poor coverage refers to that the signal level in certain coverage area is lower than the minimum access threshold of MSs. In this case, MSs cannot camp on a cell, and therefore location update and location registration cannot be initiated. As a result, call drops occur.Based on the measurement data of MSs in the GSM network, the Assistant analyzes the receive level of the serving cell to determine whether the DT points have the poor coverage problem. The following table shows the related parameters:


Alarm Threshold: indicates the poor coverage alarm threshold.Poor Coverage Rate (%) = Poor Coverage Count/Total CountIf Poor Coverage Rate is higher than Alarm Threshold, the analysis results are displayed in red in the Theme Result View window after the theme analysis is performed.

RxLev Threshold [0,500*N): indicates the receive level threshold within the distance ranging from 0 to 500*N. The default value is shown in the left figure. The unit of the distance is meter. N is an integer ranging from 1 to 10.


GSM Azimuth Garbled

Note: Azimuth garbled refers to that the antenna azimuth is configured incorrectly, which leads to improper coverage. Based on the measurement data of GSM MSs, the Assistant determines whether the DT point is within the cell coverage range.


Alarm Threshold: indicates the azimuth garbled alarm threshold.Azimuth Garbled Rate (%) = Azimuth Garbled Count/Total CountIf Azimuth Garbled Rate is higher than Alarm Threshold, the analysis results are displayed in red in the Theme Result View window after the theme analysis is performed.

Angle Threshold: indicates the angle offset threshold. The default value is 20 and the unit is degree. After Angle Threshold is set, the horizontal beamwidth is increased by 40 degrees.


GSM No Serving Cell DominanceNote:No serving cell dominance refers to that no serving cell is available in the coverage area or calls in the serving cell in the coverage area are frequently handed over. In this case, frequent handovers may occur, and therefore the system efficiency is reduced and call drops occur. After analyzing UE data, the Assistant determines the difference between the receive level of the serving cell and the receive level of the neighboring cell. If the difference between the receive level of the serving cell and the receive level of the neighboring cell is lower than the specified threshold, the DT points are considered as DT points where the problem of no serving cell dominance occurs.


Alarm Threshold: indicates the alarm threshold of no serving cell dominance.No Serving Cell Rate (%) = No Serving Cell Count/Total CountIf No Serving Cell Rate is higher than Alarm Threshold, the analysis results are displayed in red in the Theme Result View window after the theme analysis is performed.

Rxlev Threshold: indicates the receive level threshold of the serving cell.

Rxlev Diff Threshold: indicates the difference between the receive level of the serving cell and the receive level of the neighboring cell. The default value is 5 dBm.

NB Cell Count Threshold: indicates the threshold number of neighboring cells with the receive level lower than RxLev Diff(dBm). The default value is 3. If the receive level of a DT point is lower than Rxlev Diff Threshold and the number of neighboring cells of the DT point is smaller than NB Cell Count Threshold, this DT point is considered as the DT point where the problem of no serving cell dominance occurs.

Ratio of Start Distance: indicates the ratio of the start distance within a distance segment. Start Distance = Cell radius x Ratio of Start Distance

Ratio of End Distance: indicates the ratio of the end distance within a distance segment. End Distance = Cell radius x Ratio of End Distance

Bound Number: indicates the number of distance segments between the start distance and the end distance. Bound Number affects only the statistics in the chart in the Theme Detail window.

however, need to be calculated through

certain formulas. For example, to calculate the

calculation KPI Call Setup Delay Time Avg,

you must calculate this KPI through the

following formula:

Call Setup Delay Time Avg = Call Setup Delay

Time/Call Counter

Here, Call Setup Delay Time and Call

Counter are counting KPIs.

(2) The Assistant provides predefined KPIs. The

threshold parameters related to these

predefined KPIs can be modified.


Custom IEsProcedure:

1. Import data.


3. In the IE tree, choose Custom > IE.

Note:

The Assistant provides common IEs such as poor coverage, downlink interference, island, and pilot pollution. You can create IEs by specifying certain conditions based on the provided IEs. The created IEs are called custom IEs. In addition, you can customize IE thresholds. This helps satisfy the requirements of field engineers.


Automatic Import

Procedure:

1. Create a project.

2. Choose File > Automatic Project Setting.

3. Set parameters in the Automatic Analysis Setting dialog box.

Setting Description:The automatic import can be operated in either of the following modes:

(1) Time mode (automatic periodic import): This mode is mainly applied in the automatic DT scenario. In this mode, data is uploaded to a specific directory or a sub-directory on the server for automatic DT in real time. As shown in the figure in the upper left corner of this slide, you can set Mode to Time mode, and set times and Monitor path.

(2) Text mode (automatic import triggered by ok.txt): This mode is mainly applied in network optimization scenario. In this mode, DT engineers perform DT tests, analysis engineers save data in the specified directory for analysis. After a DT test is complete, analysis engineers place ok.txt in the directory, then the server automatically triggers the data import into the Assistant. This reduces the time for data import.


Exporting Data as .kml Files

Procedure:

Choose Tools > Export Logfile.

Description:

(1) Export indicators in DT logfiles as .csv files for viewing, collecting the statistics of, and analyzing indicators.

(2) Export indicators in DT logfiles as .kml files for analysis on the Google Earth. You can view these indicators on the Google Earth.


Case (1): Creating an Analysis Group

Create an analysis group by device type

Create an analysis group by MS ID

Create an analysis group by IMSI

Create an analysis group by IMEI

You can create an analysis group by MS ID, device type, IMEI, or IMSI. The functions related to KPIs, reports, or themes in the Assistant depend on analysis groups. If no analysis group is created, DT data cannot be analyzed.


Case (2): Drilldown and Data View Synchronization (Analysis of Call Drops)

As shown in the WCDMA Serving/Active Set + Neighbors window, the signal quality of the active set is poor when call drop events occur, but the signal quality of the detected set is good. Therefore, you can infer that call drops are caused by missing neighboring cells.


Case (3): Theme Analysis (Over Coverage)

3. In the Theme Detail window, view the information related to the DT points where the over coverage problem occurs.

1. Double-click a problem cell to drill down the related indicators. As shown in the figure, 58 DT points where the over coverage problem occurs are available in the cell W-YangJiaGang2.

2. As shown in the map window, the distance between a DT point where the over coverage problem occurs and the cell W-YangJiaGang2 exceeds the planned coverage range of the cell W-YangJiaGang2.
