Specifications and Key Points
for GPRS/EDGE CQT&DT Test
V1.1

HUAWEITECHNOLOGIES CO., LTD. HUAWEIConfidential
 DTtest is the most direct approach to obtain
network information. DT tests on GPRS
services in the network can collect a serial
of network data for RNO projects. By
analyzing the collected network data, you
can find and correct the existing problems
in the network, thus improving the overall
quality of the network.
 Correct and effective DT tests on GPRS
services can provide basis for our future
work.

Key Point 1: On-site Environment Detection
 Selection of test cells
 Perform lock frequency test to avoid handovers
 Select the best test route
 Selection of test time segments
 Select non-hot spot cells for the test
Signal level in the service cell – signal level in neighbor ≥20dB

Key Point 2: Requirements for Test Terminals
•Composition of typical drive test equipment
Information of
SIM card
Multislot
capability
Connected to
the laptop
Disconnected with other
networks
Close network access
tasks
Change TCP window in
the register table
Set GPS
correctly

Key Points 2: Requirements for Test Terminals

in PDP context
setting
NCK mode on LLC layer
ACK mode on RLC layer
•SIM cards used for test

Key Point 3: FTP Server Used for Test
Test FTP address
provided by the
operator
•Select FTP servers with reliable performance for test

key Point 4: Selection of Test Software
 Drive test software used by Huawei
