on.

To analyze drive test data by using the GENEX Assistant, do as follows:

1 Install the GENEX Assistant The GENEX Shared components must also be

installed.

8 Display the data in the format of map, chart, or table, and analyze the data.

9 Generate various kinds of analysis reports.

10 Generate a final report based on the analysis reports and the data exported.

Workflow of the GENEX Assistant

Precautions for Data Analysis Through the

GENEX Probe and GENEX Assistant

Before the analysis, obtain the test files from the related owner and check the test records

to know the general details of the test

The version of the GENEX Assistant must be the latest If you are not sure whether the

version is the latest, contact the project leader

Auto combination and UE combination can be used for the data import of the GENEX

Assistant Pay attention to the differences between the two combinations Currently, the Auto combination is recommended The differences between the two combinations are as follows:

• Auto combination

• 1 This combination is applicable to the case that multiple files are divided during a drive test.

• 2 Each UE is used for testing the same service.

• 3 Time overlapping cannot occur in data Events are judged according to signaling Therefore, if time

overlapping occurs in the data, calls overlap with each other and the events are misjudged.

• UE combination

• If time overlapping does not occur in two UEs and the time difference is greater than 10 seconds, the

events of the UEs are accumulated but not re-judged.

• If time overlapping occurs in two UEs, the time of the latter UE is offset by one day so that the time

overlapping can be avoided.

• If the IMSIs of two UEs are different, the events of the UEs are accumulated but not re-judged.

Precautions for Data Analysis Through the

GENEX Probe and GENEX Assistant

The GENEX Assistant can perform all the chart statistical functions and analyze

problems Analysis engineers need to be familiar with the signaling process

Moreover, the GENEX Assistant can replay data The GENEX Probe is used for foreground tests, and the GENEX Assistant is used for background analysis

By using the GENEX Probe, you can collect statistics and provide charts and

reports If you need to observe more indexes for locating a certain problem, you can use the GENEX Probe to replay data Currently, the software version is updated frequently Therefore, it is suggested that you start the GENEX Probe

during the replay and choose Configuration > System Configuration > Others >

Event Re-judge to re-judge data events Pay more attention to the replay of

earlier data

Three data sampling modes:

•Average value: indicates the average value of the data collected from all points in an area after the currently performed binning

•Max value: indicates the maximum value of the data collected from all points in an area after the currently performed binning

•Min value: indicates the minimum value of the data collected from all points in an area after the currently performed binning

•Data dispersing:

Disperses the data In the case of bus stop in a drive test, test data is concentrated on one point The GENEX Assistant disperses the data collected during bus stop into the data collected several seconds

before the bus starts off In this way, the data can be evenly displayed on the map

You need to select special data processing methods for different scenarios.

Data binning can effectively reduce the affects brought by fast fading.

No Binning

No binning is based on the analysis of original test data In general, no binning

applies to the synchronous analysis of events and signaling

Advantage:

You can locate each event and signaling, and solve the problem

Disadvantages:

You need to process a large amount of data

The original test data is distributed in a non-coherent way

Data Binning

Distance Binning

Distance binning is usually used to analyze drive test data, and can also be used to quickly process the CW test data and analyze the network coverage

Advantages:

Distance binning samples data by equidistance on the unidirectional route

Distance binning avoids congregation of sampling points The point congregation can be caused by long time stops, for example, the car stops caused by traffic stop signals

Distance binning is of high efficiency

Grid Binning

Grid binning effectively complements the geographic binning mode by being applied to repeated routes.

Advantages:

Grid binning can be used to perform geographic binning on repeated routes.

Grid binning avoids congregation of sampling points caused by long time stops For example, the car stops because of traffic stop signals.

Grid binning is of high efficiency.

Disadvantages:

Time delays occurs on the repeated routes.

The size of the grid cannot be too large.

Example of data binning: compares the average data before and after the grid binning which takes 5 meters * 5 meters as a grid.

5m x 5m

Data Binning

Time Binning

Time binning requires that the vehicle runs at a stable rate and can be used to analyze special KPIs within a continuous

period.

Advantages:

Time binning is used to analyze the data that is tested at a stable rate.

Time binning samples the maximum or minimum data by using a predefined interval within a continuous period, and

analyzes some special KPIs.

Time binning is of high efficiency.

Disadvantage:

If the vehicle runs at an unstable rate during testing, the intervals of test data cannot be the same.

Example of time binning: compares the average data before and after the time binning which takes 1 second as interval.

1 second

Low speed

Data Binning

High speed

Time Binning

For example, to learn the BLERs in some intervals, you need to:

1 Set Binning Param Time Span (s) to four.

2 Set Value Fetch to Min Value

The table below shows that the minimum BLER value within four seconds is greater than 5%

In this case, you can infer that problems may occur during data transmission

The minimum BLER value within four seconds is greater

than 5%

Data Binning

The GENEX Assistant can support the test data of the following devices:

Importing Test Data
