Drive Test

1.3.1

Install the GENEX Probe software on PC Install the Probe software on PC according to chapter 4.4 of User Manual. Chapter 5 introduces the Graphical User Interface of Probe.

1.3.2

Prepare the Engineering Parameter File Engineering Parameter File is optional, but it is recommended so the engineer know which is the nearest NodeB, further more Probe will draw a line between the current locate and the NodeB the UE camps on.

1.3.3

Connect the UE to PC and install the driver for the test mobile 1、 Power on the UE 2、 Set the diagnosis port of the UE to USB port: Press the three keys at the same time (*, #, and “Left” key) to enter the engineering mode, then press “Others” - “DIAG port set” - “USB DIAG”. 3、 Make sure the driver files are already on local disk. For example in folder F:\U626_Driver\WinXP. 4、 Connect the UE to the USB cable; plug the other end of the cable to a USB port of the PC, then followed by steps below:  A dialog like Figure 1 -1 will appear in a few seconds:

Figure 1-1 Step 1 of UE driver installation

 Choose the button as Figure 1 -1 shows. Then click “Next”. A dialog will appear as Figure 1 -2:

Note1: For the Com port, fill the 3G Application port got from Figure 1 -8. Note2: For PS service test only, here fill the serial port of the Modem got from Figure 1 -9. 3、 Setup the DTI scanner like Figure 1 -14:

Figure 1-14 Scanner (DTI scanner) configuration

Normally DTI scanner is connected to the onboard serial port (com1) of the PC. If it is connect to some other serial port such as USB-to-Serial port, please get the right port from the Device Manager (see Figure 1 -8). DTI scanner has a GPS internal, so it’s no need to configure GPS. 4、 After configure the Huawei U626 UE and DTI scanner, click the port test button as indicated in Figure 1 -12 to check the devices.

Note: Only the device checked successfully could be identified by Probe system. If any item checked failed, please check the hardware connection, the equipment parameters such as port and baudrate, etc. 1.3.7

System Config - Test Plan Including Test Plan, LogMask, Event, Alarm and Other related settings. Here we focus on Test Plan. Other settings keep default. For more details, refer to chapter 6.7 setting the system. 1、 Click menu “Configuration” - “System Config…” to the system config interface. Figure 1 -15 shows how to configure a video call. 2、 Note for Figure 1 -15: Action 1: choose device, first choose UE1 Action 2: click the TestItem bar to choose a service we would test. Choose Video Phone. Action 3: Set the parameters for Video Phone service test: Enable: True to enable the test item Destination Number: the number being called Setup Time (sec): keep the default - 25. Calling Duration (sec): fill it 105. Call Interval (sec): fill it 15 (Default value is 15, too). Exceptional Interval (sec): keep the default - 20. Call Count: total number of calls. In this exercise the test will last about 2 hours to 4 hours. From the given parameters we can calculate one call will last about 135 seconds (5sec+105sec+15sec). So the count will be about 4*3600/135≈107 times. It is suggested to set a count big enough to ensure the video call will go on testing until the test is stopped by the engineer. Here we set 300. Note: More details about the parameters above, see section 8.2.1 and 8.2.2.

3、 Like action 1 in step 2, choose Scanner1 to configure parameters for scanner. Figure 1 -16 and Figure 1 -17 is the config interface. DTI scanner can provide 6 test functions. We only need TopN Pilot Scan. So just enable it, others functions keep them disable. Figure 1 -17 says for TopN Pilot Scan we only need to set the channel. It equals the downlink frequency (MHz)*5. For more details about other parameters, see chapter 8.3.

Only enable TopN Pilot Scan

2.2.2

Prepare the Engineering Parameter File Engineering parameter may assistant engineer to analyse data more efficiency. Note: Up to now, the required format of engineer parameter in Assistant is not same as in Probe. Please pay attention to the different format of the frequency and PSC in the parameter file.

2.2.3

Create a project Referring to section 5.2.1, create a new project. Then Assistant will prompt a “New Dataset” dialog to create a dataset. Or we can open a previous saved project according to section 5.2.2.

2.2.4

Create a dataset When a new project is created, Assistant will prompt a “New Dataset” dialog to create a dataset. Or we can create a new dataset to a project according to section 5.3.1. The parameters in “Scanner Setting” tab, normally it is recommended to set as the RNC parameters. For this practice, we keep them default. Parameters in “Binning Type” tab are kept default, too. Now the interface may look like Figure 2 -18.
