Application Testing Introduction
1 Introduction
Rohde & Schwarz test instruments are well established in the field of radio communication and protocol
testing, but some customers have identified the additional need for testing the actual data functions and
pplications of mobile phones under clearly defined, and reliably reproduceable, conditions. In essence,
a
emerging technologies have demanded a broadening of the testing focus, as applications are
increasingly integrated into mobile devices.
The solution here described facilitates Application Testing on a network simulation of (E)GPRS,
CDMA2000, or WCDMA, and requires the relevant options for the R&S CMU200. It also relies on a
group of software packages, whose installation and configuration are described in this document.
For all three network options, installation of the Application Test Environment (ATE) software makes
available various application enablers and testcases: for example, an MMS server, with which sending
and receiving MMS messages can be tested.
Although the option of a live internet connection is supported for each of the network simulations, this
document describes a test setup which, instead, uses a "Server PC" to provide the various required
services within the simulated network.
In the chapters that follow, some familiarity with IP addressing and TCP Ports is assumed, but an
overview of these topics is provided in Appendix A.
General guidelines are given for the whole process, from installation through to running the actual tests,
and more specific guidance is given for some of the required settings (especially those which are less
intuitively accessible). However, for fuller coverage, please refer to the relevant document for the
product you are using.
Although the current document is particularly directed towards the Universal Radio Communication
Tester, i.e. the R&S CMU200, the test procedures it describes apply equally well, overall, to R&S CRTU
Protocol Testers that support the same network simulations.
Hardware and Software Requirements
Application Testing is carried out in a special test environment which simulates a radio network and
offers access to various IP Data based services (e.g. servers for file and message transfers, and for
video streaming). There are specific hardware and software requirements for the R&S CMU and the
Server PC, as follows:
R&S CMU200
Network Support R&S CMU Options
(E)GPRS R&S CMU-K92
CDMA2000 R&S CMU-B87, R&S CMU-
K87
WCDMA R&S CMU-K96

Introduction Application Testing
Server PC
or Application Testing over (E)GPRS, you must use a PC that has an available Ethernet port (at least
F
100 Mbps) and is running either Windows XP or Windows 2000.
For Application Testing over WCDMA or CDMA2000, a free Ethernet port (at least 100 Mbps) is
required, but no particular platform is necessary, as long as the various IP Data based facilities are
supported. Of course, if you wish to install any of the specific IP Data based packages described in this
document then the Windows requirement still applies.
Client PC
Application Testing when the phone is being used as a modem needs a Client PC attached to the
phone. There are no particular requirements for this PC, except that it can provide the relevant IP Data
based support as required.
Configuration
1. A consistent set of IP addresses and TCP Ports is required on the R&S CMU, in the software
installed on the Server PC (and Client PC), and in the mobile phone under test. The IP addresses
and ports used throughout this document are not mandatory, but if you use different values you
are advised to comply with IANA guidelines for non-routable addresses and port numbers.
2. Mobile phones are usually supplied with preset factory settings, typically relating to a particular
network operator. During MMS testing, for example, it is important to make sure that the
message centre address is changed to that of the MMS server within the test environment.
The configuration steps are described below, but for the mobile phone it is not possible to provide exact
instructions: there is no universal manufacturer agreement on naming conventions, or on menu layout.
It is common to find significant differences even between different models from the same manufacturer.
However, the guidelines that are given should be enough to locate and set the relevant values.
General System Arrangement
The layout of equipment and software is largely the same for all of the tests described later, but the
exact setup depends on the chosen network environment and whether the mobile phone is being used
standalone or as a modem for the Client PC.
The general system arrangement for Application Testing is shown in Figure 1. All tests require a PC to
be attached to the R&S CMU, and this is referred to as the "Server PC". A second PC, attached to the
phone and called the "Client PC", is needed for tests that just use the phone as a modem, such as the
FTP session.

2 Connection Configuration and Settings
The following sections describe the steps necessary for correct configuration and setting of connections
between the R&S CMU200, Server PC, Mobile Phone and, when required, the Client PC.
Note: The IP Addresses used throughout this document form a consistent set that is recommended
for your own test setup, but their use is not mandatory. However, if you choose different IP
addresses, it is recommended that you follow IANA guidelines
non-routable addresses (i.e. "private IP addresses").

Note: the Ethernet card must support speeds of
at least 100 Mbps.
Figure 2 TCP/IP Properties
(2) Only for (E)GPRS Application Testing, a special PC-based software package called the Data
Applications Test Suite (DATS) is required. For correct DATS configuration, the following IP
addresses have to be set on the Server PC:
Open the file prostacklink.ini in the C:\OPSW\<version>\CR02P2P folder.
[Config]
CMU_IP_ADDRESS=192.168.168.170
WS_IP_ADDRESS=192.168.168.169

Connection Check
With all settings made for the connection between Server PC and R&S CMU, we can now check that
the connection works:
First make the physical connection between the R&S CMU and the Server PC using a crossover
Ethernet cable (Cat 5/RJ-45). Note that the R&S CMU has two Ethernet ports:
a) The upper port is labeled Ethernet B-87 and should be used for CDMA2000
b) The lower port is labeled Ethernet B-56 and should be used for (E)GPRS and WCDMA.
Open a Command Prompt window (Start|Run|cmd) and type: ping 192.168.168.170 <Enter>
If the two devices are properly connected, the system confirms a response from the R&S CMU and
reports the time taken for the "round trip". If there is a problem with the physical connection, you will see
a message that the Ping has timed out. If the IP address setup is wrong, the system reports that the
Host cannot be found.
Ping is a very useful command, and perhaps the easiest way to confirm "mutual reachability" across a
connection. For details of the command options, type "ping /?".

Run a simple test to confirm that the RF connection between R&S CMU and phone is working correctly:
Set up a link between the R&S CMU and the mobile phone by means of a simple RF measurement,
with the settings just entered for frequency and power level, and additional channel configuration and
coding.
Mobile Phone - Client PC
For Application Testing when the mobile is being used simply as a modem, a second PC is included in
the setup. This is termed the "Client PC" and is attached to the mobile phone.
Mobile Phone
Arrange a suitable connection between the mobile phone and the Client PC: a serial cable link, or a
connection that uses either Bluetooth or infra-red. Consult the phone's operating manual for guidance.

Client PC
The objective in this section is to create dial-up networking on the Client PC. However, before you can
o that you must install the relevant driver for the mobile phone to which the PC is connected. The
d
software for that, along with instructions for installing it, are usually available for download from the
manufacturer's website. Once the relevant driver is installed, you then create the dial-up-networking so
you may then setup a packet connection from the Client PC, using the mobile phone as a modem:
Open the Network Connections window, click New Connection Wizard.
Click Next Click Connect to the Internet, click Next.
Click Set up my connection manually, click Next. Click Connect using dial-up modem, click Next.
Select the modem for your phone, click Next. Enter *99# for WCDMA/(E)GPRS packet data,
Enter CMU200 as ISP Name, click Next. or #777 for CDMA2000 packet data, click Next.
