Radio network optimization (RNO) is the important step in network construction.

RNO adjust the planning and design reasonably , improve the network coverage,

increase the network capacity, improve the network service quality and resource

utilization ratio. Make the network operation more stably , and provide excellent

service.

Data collection is the necessary premise of analysis and adjustment. Optimization

data including：Driving test data（DT）,Call quality test data（CQT）,OMC

performance data, Customer’s complains, Alarm data , signaling data and other

data.

ZXPOS CNT ( UMTS Edition， for Short CNT) is the professional network

optimization test software developed by ZTE . CNT helps the RNO engineer to do

the test and analysis. Locate network problem and evaluate network quality and

capacity, constitute the optimization solution.

Edit the site information table

Create map and design testing route

UE driver installation

Software installation

Hardware license driver installation and upgrade

Connect the equipment

Build the test environment

Preparation Edit the site information table

CNT can support Excel format site information table load and unload, the

detailed content you can check the attachment：

The requirement of the site information table, at least must including 9

parameters as follows:

Preparation Create map and design testing route

2 methods to create map：

1. Import the MapInfo format map

2. Use MapInfo convert JPG or BMP format file to Tab format file.

Steps of convert JPG or BMP format file to Tab format file ：

1. Download the city map via the accessorial software ( for

exampleSupperget2000 series ).

2. Use MapInfo open the map

Figure ①



3.Click <Register> on figure 2 to calibrate the map。

4. Select 3-5 points from Google earth or by GPS test, Click <Add>，Enter the

right longitude and latitude as figure 3 and figure 4.

5.Click <OK>，the software will generate map automatic, then the calibration is

finished.

Method to design the testing route：

Some times you need prepare the testing route at first, The method to design

the route in MapInfo as follows:

1. Open MapInfo, open the map file. Click <New Table>, Create a new layer

on the map layer. The detailed setting see figure 6 and 7.



Figure ⑥ Figure ⑦

2. Save the file to certain folder

3.Click [Map →Layer Control], select the pop-window from layer control window,

add the new layer just now created. The detailed setting see figure 8



Figure ⑧ 4. Now the new layer is displayed in the status bar, Select the drawing tools to design

the testing route. See figure 9.
