Several equipments that use in drivetest :

1. TEMS Handset (complete with Charger, Headset, Data Cable) and USB Hub

2. Laptop (installed TEMS Investigation) and Adapter

3. GPS (Ext Antenna and Data Cable)

4. ATEN (Serial to USB)

5. Scanner for WCDMA (Ext Antenna GPS and RF, Data Cable)

6. Inverter and Terminal

7. Battery and Charger

Example postion of that equipments in car :

1. Power Management

Set Power Management Laptop always On :

Start -> Settings -> Control Panel -> Power Options -> Set All Power Scheme “never”

2. Virtual Memory

Set Virtual Memory :

Start -> Settings -> Control Panel -> System

Advance -> Performance Settings

After installition process, open Tems Investigation.>> All Programs -> TEMS Investigation -> Data Collect

This is the example workspace for 2G (Mode Dedicated-Idle).

1. Open Worksheet Map & arrange size of window Map

2. GPS (Presentation -> Positioning -> GPS)

3. Port Configuration (Configuration -> Port Configuration)

4. Command Sequence (Control -> Command Sequence)

5. Serving + Neighbours GSM (Presentation -> GSM -> Serving + Neighbours GSM)

6. Current Channel (Presentation -> GSM -> Current Channel)

7. Event (Presentation -> Signalling -> Events)

for benchmark workspace, add Serving + Neighbours GSM and Current Channel for MS3.

Herewith the example of command sequence in TEMS 6.1.4

Voice Call CS

i.e “120/15” means 120 second on call then call end, 15 second wait and then call again.

1. Loop Start give the number of repetition for command below the loop start (General -> Loop Start)

2. Dial select the MS and give the destination number (Voice -> Dial)

3. Synchronize to synchcronize MS before go to the next command (General -> Synchronize)

4. Wait 120 wait 120s on call (General -> Wait)

5. End Call (Voice -> End Call)

6. Wait 15 wait 15 before call again (General -> Wait)

7. Loop End (General -> Loop End)

Video Call CS

In general cs for video call is same as voice call, but in video call in dial command we must add “v”.

i.e

Loop Start

Dial v081384760975

Wait 120

End Call

Wait 15

Loop End

 

1. Configure Recording Properties : Menu Tab Logfile -> Recording Properties

2. Select recording folder : Click Browse -> Select Directory

3. Select Quick logging and setup size of swap file “after reaching message “

4. Use 2G or 3G configured workspace (with spacific map : road, route, cell file)

5. Make sure all equipments configured to the right port

6. Connect all 

7. After all equipments connected (symbol green), window gps, serving neighbour gsm, current channel and events will be full filled

8. Don’t forget to lock TEMS Handset into GSM only or 3G only.

9. To start drive test, click record then start command sequence

10. After all route complete, wait untill call end then stop command sequence and stop recording.

Here the flow step by step Go Drive Test !!!
