1.Huawei Datastick1)Insert the Huawei datastick into any laptop USB port2)Wait for all “Found New Hardware” icons to disappear. Note this can take a few minutes

3)Click on Setup to begin the installation process. Follow the on-screen instructions to complete installation

4) Once installation has been completed, go to Device Manager. From the desktop, right-click on My Computer Properties Hardware Device Manager Expand on Modems & Ports.

5) Go to next folder step 2 and execute the firmware update.6) Go to next folder step 3 and install the Tmobile connection manager(if it not been installed already). If it says uninstall say no that means its already been installed in the system7) Go to next folder step 4 3 and install the mobile Partner.

Huawei Datastick1.The datastick provided will be set to Automatic mode. This needs to be changed before Cluster drive testing (S11, S12 scopes) occurs as per the following section. NOTE THAT THESE STEPS WILL NEED TO BE PERFORMED EVERY TIME BEFORE A DRIVE TEST OCCURS / LAPTOP REBOOTS / USB PORT CHANGED. The process of locking the Huawei datastick to either WCDMA / Automatic mode only appears to apply for the current drive test. Once the datastick is removed from that port / laptop rebooted, the current setting is no longer applicable. Testing with multiple laptops shows inconsistencies with the command being applied hence it is advisable to err on the side of caution and always check the current state of the device.

Network Selection:To lock the UE to the WCDMA mode only (Required for S11 & S12 scopes):1) Go to Start All Programs Mobile Partner Mobile Partner

2) Go to Tools Options Network Under Network Type: Set Network Type to be WCDMA Only & Band Automatic. Click Apply Ok

Close the Mobile Partner software. To check whether the command was successfully applied Start TEMS Investigation 8.2.5 and initiate a HS call. Specifically, expand the “RRC Connection Setup Complete” message. Look for “supportofGSM : True” as shown.

Dial-Up NetworkingDial-up Networking involves setting up connections for packet services. Each phone which will be used forpacket services needs a separate dial-up connection. •Go to My Computer Right-click to show Properties Hardware Device Manager Modems Huawei Mobile Connect – 3G Modem Right click to show Properties Advanced Type the following: at+cgdcont=1,”ip”,”internet2.voicestream.com” The above AT command will need to be entered for any UE that will be used to perform R99 / HSDPA testing.

Ports & Equipment Configuration

When all devices that will be used have been powered on and connected to the laptop, the specific port assignments for each device can be checked by going to the My Computer Properties Hardware Device Manager Expand on Modems & Ports. Each device should appear in both the COM Ports & Modem sections.Once all the required devices have been added, click on the Connect All button (or F2) as shown below to connect all the devices to the various ports. If all the devices are successfully configured, there will be a green symbol per row to signify this. The UE to EQ mapping can be changed via the following if required (Note that this needs to be performed before connecting any device, i.e.; when all the symbol colors are red):•Right click on EQ item (EQ1, EQ2 etc ;) •Select a new number to change the EQ Index. If an index is chosen that is already taken by another device, the two devices will swap indices•Click Save to save the current configuration

Common resolutions for undetected ports are:1)Swapping devices to new ports and attempting to reconnect with new port allocations2)Incorrect software versions for the device may cause problems with detection3)Restarting laptop / software / UE / scanner device

With TEMS Investigation 8.2.5 most devices are auto-detected and enabled automatically. The following are the general conditions under which this is true:•Most UEs (excluding the Huawei datastick) are auto detected•PCTel scanners are the only scanners that are auto detected•GPS units that use the NMEA protocol as well as Garmin GPS 18 are auto detected.

Huawei Datastick Ports Configuration

The datastick is not automatically detected within TEMS 8.2.5. Instead, the user is required to manually add the device and select the correct ports. Following are the steps required to achieve this.1)Go to Device Manager. From the desktop, right-click on My Computer Properties Hardware Device Manager Expand on Modems & Ports.

From Modems, select Huawei 3G Modem Right-click Properties Select the Modem tab. Note the Com Port number. It is Com Port 27 for this exampleFrom Ports (COM & LPT), note the Com Port number for 3G Application Interface. It isCom Port 28 for this example

1.Scanner Setup1.The PCTel SeeGull EX scanner is used to perform scanner measurements (for both UMTS UARFCN and GSM ARFCN set). The SeeGull EX scanner connects via USB. The PCTEL Scanner drivers would have been copied after the entire drivers folder was copied from Section 6.1:

C:\Program Files\TEMS Products\TEMS Investigation\Drivers_TEMS_8.2\PCTEL\EXWhen connecting the Scanner to the laptop for the 1st time, the hardware installation wizard will look for a suitable driver. Choose the ‘Specific Location’ choice and then point to the link given above. The Wizard will install the driver for PCTEL scanner.Once the scanner is powered up and connected via USB to the laptop:•On the Equipment Toolbar choose scanning device (MS1) in the left combo box and choose “WCDMA CPICH Scan” in the right combo box•On the Equipment Toolbar click the “Scan Properties” button to reveal the below window

GSM Setup

•On the Equipment control toolbar, in the scanning task combo box, select “GSM Frequency Scanning”•Click the Scan properties button•The measurement settings dialog appears as shown below

1.Command SequencesCommand Sequences are used to automate testing of both voice and data services. They are scripts that allow TEMS to make calls automatically without user intervention. These commands are sent to the phones to inform them of call sequence flows. Command sequences have been created for the various UMTS Acceptance test cases and for the ATL & SNQ FTP servers. Due to frequent changes that have occurred with the command sequences, these files are now available at the following location: These files can be imported as follows:•Within TEMS, go to Control Command Sequence

Figure 50: Command Sequence Selection•Click on the Open button or Control-O in the command sequence window and select the correct scope command sequence xml file.

Figure 51: Command Sequence Import

Following are the command sequence changes that DT Operators will need to make before commencing each drive test.•Ensure correct device to com port mapping•FTP DL: Ensure Phone book entry exists on the laptop – the default entry “Huawei” was created on the author’s laptop•FTP UL:

Ensure phone book entry exists Ensure UL source file exists on DT laptop Ensure UL target file changed to correct target directory / file

1.Drive Test Operation1.As all the various stages of setting up the drive test process have been clarified, the following section will provide an overview of steps to take within TEMS Investigation to start the drive test.

•Open TEMS Investigation 8.2.5 File Open Workspace Choose the relevant workspace for the scope to be driven •Go to the Ctrl & Config tab•Connect the USB cable from the existing 7 port HUB to the laptop. Ensure the PCTel Scanner & Samsung / Datastick are correctly configured according to the scope port numbering•If all equipment has been detected by TEMS, the following screen should be seen

Figure 52: Ctrl & Config Window

•The equipment configuration for the majority of Acceptance test cases will be:1)EQ1 = Scanner2)EQ2 4 = Samsung UE / Huawei Datastick

•Ensure a Dial-up connection exists and the Com Port has been correctly assigned for the UE executing data calls. For eg; in the above figure, DC4 is attached to COM 17. It’s corresponding Dial-Up connection should be connected to COM 17 only•From Control Command Sequence, ensure the correct command sequence xml file is loaded for that particular drive•Ensure an UL file exists for the UL FTP and correct directories have been set to store the log files. Ensure the prefix has been set as per the naming conventions from Section 8.1.•For command sequences that require manual user intervention, press ‘Start Recording’ or F6 to start log file recording otherwise Press Run from the Command Sequence window or Ctrl+G to initiate the command sequence. •To start the scanner, select MS1 from the top left corner (below File Menu) and then from the next drop down menu, select ‘WCDMA CPICH Scanning’. Press start scanning or Ctrl+J to start the UMTS scanner. Ensure that GSM measurements are also being collected•Call sequence termination occurs either manually or automatically according to each scope. Cluster Drive (S12)a. Automatically occurs after 30 mins if no drop call occurs for MS3 Cluster Drive (S11)a.Manual intervention required to start & stop logfiles. Ideally, each stationary location should have only 1 log file

Cluster Drive (S13)Manual intervention required to start & stop logfiles. Ideally, once the logfile has reached approx 100MB / 30 mins have elapsed, the drive test operator should start a new logfile.•Swapping of the log file should occur when all handsets are on idle mode. To ensure this happens, stop the command sequence by pressing the STOP button or Ctrl+H. It is recommended to STOP the command sequence when MS4 (PS FTP) comes to idle mode (after hearing the PS Detached message). You will find MS4 in idle mode when the phone is in ‘WAIT’ period on the command sequence window.•Now press ‘Swap Logfiles’ or F4. This will automatically create a new log file with the original filename specified but with a different log file number.•At the end of the drive, stop the logfile by pressing ‘Stop Recording’ or Ctrl+F6•Press the ‘Disconnect All’ icon or Ctrl+F2 to logically disconnect all the equipments connected to TEMS. The devices can then be powered down and USB cables removed from their respective USB slots•At the conclusion of the drive test, rename the 1st log file by adding a suffix ‘_01’
