The document discusses drive testing using TEMS Investigation software. It provides an overview of the tools needed for drive testing including a laptop, dongle, mobile set, modem, GPS, and more. It outlines the steps to setup the software and ensure all tools are connected and functioning properly. These include attaching the required devices, loading cell files, and selecting the log collection location. The document also describes some key parameters that can be analyzed during drive testing like signal strength, interference, and throughput.

9. Step 1 Go file Menu Select
Configuration Menu Then General
Submenu

10. Step 2 Go file submenu Select General
then select Submenu Cell File Load

11. Step 3 Go file submenu Select Cell File
Load After Click There Open A new
Window

12. Step 4 new Window Click Add there
open a new window

13. Step 5 select a location Where U
Store Cell File

14. Step 6 select a location then Click ok

20. GSM Neighbors
This window is very helpful in case of 2G – 3G Handovers as we can see all
the 2G neighbors of that particular 3G cell in the compressed mode state.

21. Serving/Active Set + Neighbors
 Cell I.D – This is the identity or name given to
a particular Node B and its cell by the
operator.
 UARFCN – It is the frequency band allotted to
the operator. One spectrum bandwidth is of
5MHz in WCDMA or 3G.This window shows
us the centre frequency of the bandwidth
allotted to the operator.

22. Serving/Active Set + Neighbors
 Cell Name – It is the name given to particular
Node B’s by the operator generally along the
lines of the name of the area the Node B is
located in.
 Scrambling Code – Scrambling code is a
code assigned to a particular cell. There are
512 such codes for the network to differentiate
among different Node B’s and these codes
can be repetitive. They are of two types
primary and secondary.

23. Serving/Active Set + Neighbors
 AS – This stands for Active Set. Active Set is the
set of Scrambling Code which the U.E is currently
latched on and there can be a maximum of 3
Scrambling codes in Active Set.
 MN – MN Stands for monitored neighbor i.e. the
neighbor cell that is detected by the U.E as a
neighbor and is also defined as a neighbor in the
network. U.E will initiate a Handover onto the
monitored neighbor in case the monitored
neighbor has a stronger RSCP or EcNo than the
AS.

24. Serving/Active Set + Neighbors
 DN - DN stands for Detected Neighbor and as the
name suggests it is the neighbor detected by the
UE but, is not defined in our network . Hence, the
U.E does not handover to the detected neighbor.
It can be because of Overshooting of a site,
incomplete neighbor list or in case of a new site. It
is very important to optimize and have no DN’s as
they are one of the major reasons of Call drops in
3G.

25. Radio Parameters
 CPICH Ec/No – Common Pilot channel Ec/No
is the ratio of energy of the chip and the
combined power of all the signals including
the pilot itself received by the UE at that
particular point. It is a very important factor for
call quality.
 CPICH RSCP – Received Signal Code Power
is the level of the signal received by the U.E
from a particular pilot.

26. Radio Parameters
Radio parameters are the parameters of a Mobile
equipment –
Tx Power – As the name suggests it is the transmitting
power of a Mobile Station. Its value can vary from
-50 to 50. The minimum the Tx power of the Mobile
station the better it is for call quality.
UTRA Carrier RSSI - It is the Received Signal Strength
Indicator of the Mobile Station or the U.E. It tells us the
total Power Received by the Mobile Station from all the
Pilots including itself at that particular location.

27. Radio Parameters
 SIR – It is the signal to interference Ratio is
the ratio of Energy in the DPCC(Dedicated
Physical Control Channel) to that of the
interference and noise received by the U.E.
 Target SIR – It is the target Signal to
Interference ratio that Mobile Equipment is
supposed to achieve by increasing or
decreasing its power. It is set by the use of
Power Control procedure.

28. Radio Parameters
 SQI - It is the speech Quality Index which is a
parameter to rate the voice Quality on that
particular call. It ranges from 0 – 30 with 30
being the best quality.
 RRC State – It tells the current state and
channel as in Idle or dedicated.
 Mode – It is the mode that we are using GSM
or WCDMA.

29. HSPA/GSM Line Chart
 This window gives us the data speed for both
3G and 2G modes depending on which mode
the mobile equipment is.
 RLC DL Throughput – This is the total
throughput on the downlink at that particular
point.
 The speed shown in this window as
throughput is in Kilobits/sec.
