Introduction

The Agilent Technologies E6701A Lab Application shortens the GPRS wireless appliance design cycle with a one-box solution for parametric and signaling design validation. The E6701A Lab Application (LA) is an option for the Agilent 8960 Series 10 (E5515B or E5515C) Wireless Communications Test Set. With this option, R&D integration engineers working on functional verification of GPRS wireless appliance firmware and hardware now have access to a flexible, comprehensive, and easy-to-use one-box solution for quickly and accurately

validating a product’s parametric and signaling design requirements.

The Agilent 8960 Test Set, the industry standard for testing cellular handsets, now accommodates many requirements of GPRS wireless appliance R&D engineers. The platform’s new E6701A software retains the measurement and call processing capability of the E1964A GPRS Mobile Test Application, which establishes a vital link between design and manufacturing. The ability to use the same equipment in R&D and production allows for a rapid and smooth transition from one phase in the product lifecycle to the next, as well as improved troubleshooting processes.

The Test Set’s protocol logging capabilities facilitate testing and troubleshooting of new signaling features and data channels, so engineers can extract better information about their designs. Two-way IP data communication, when set up between a device and a network, provides real data flow on a real data channel, enabling R&D integration engineers to test more of the data handling performance of a GPRS device. Users of the E6701A can set timing advance and cell parameters, which allows for testing and troubleshooting issues related to timing and base station configuration.

Network Setup

This tutorial is designed around using a Local Area Network (LAN) which is also connected to the Internet. Your PC or your test set may already be connected to this network. If it is connected, you will need to know the address method used, and collect valid IP addresses for the test set, the PC, and the wireless Device Under Test (DUT). You will probably want to contact your Network Administrator in your IT department. You will also want to know the network Subnet Mask and the network Gateway address.

Many LANs use a combination of static and dynamic (DHCP) IP addresses; others use only static IP addresses.

LAN Addresses

Write the addresses you received from your network Administrator here: Test set IP address: ___________________________ DUT IP address: ___________________________ (The DUT Address must be on the same subnet as the test set address) PC IP address: ___________________________ Subnet Mask: ___________________________ Network Gateway address: ___________________________

Test Set Setup

1. Turn on the test set or press the blue SHIFT key, then the green Preset key to reset it.

2. Press the SYSTEM CONFIG key. This displays the System Config Screen.

3. Verify the test application: GPRS Lab Application, E6701A, A.01.10

are NOT selected.

5. The Observation Points correspond to seven protocol layers you can log. Logging data

will only be collected for layers that have been selected prior to the start of logging.

• L1_Interface Raw information between the DUT and Test Set

• RLC/MAC Access and control messages

• LLC Unnumbered and supervisory messages

• GMM/SM Attach, detach, security, and PDP context messages

• GSM_L3 Common control channel messages

• SNDCP Network-level messages

• IP IP datagram data and control fields

6. Buffer Operation: for this tutorial, select Linear.

• The Linear buffer stops the log when the logging memory location is full.

• The Cyclic buffer writes over the oldest data once it is full.

7. Scroll to the bottom of the page.

8. Enter a User Comment if desired to annotate the log. This must be alphanumeric

characters only, up to 74 characters in length.

9. Select OK to save the setup and return to the main logging page.

10. Select the Start Logging icon.

11. Turn on power to the phone (to perform a switch-on and attach).

Motorola Timeport Example:

• The phone should indicate service signal-strength bars (in the upper-left corner of

Wait a few moments. The PC display will update as new data is captured in the Test Set.

Product Feature: Ping

Ping is a tool to help check system interconnects. Ping is only available in IP Data mode. The Test Set uses Ping to send a 64-byte packet to the device being pinged. If the connection is good, then the device will return a packet to the Test Set and the packet transfer information is displayed on the Test Set’s screen. Note: you can make a protocol log while performing a ping to a DUT (phone). (Note that the Test Set can only log data that travels through the RF link, such as a DUT ping).

1. On the Test Set, go to the Call Setup screen.

2. On the Control (left) column of softkeys, press the More key until you see 2 of 2.

3. Press the Ping (F3) key

Pinging the DUT (the phone or wireless device)

Note: You can log a DUT Ping because the data travels through the RF link. Set the Observation Point to IP, start logging, then perform the ping below.

1. Press the Ping Setup (F1) key again.

2. In the Ping Setup table, set the Device to Ping to DUT

3. Because it may take a phone over 5 seconds to respond, set the Ping Timeout Value to 10

(seconds).

4. Verify that the Test Set Active Cell field indicates Attached.

5. Create an active PDP Context, generally by instructing the device to start transferring

data.

Motorola Timeport example:

Press the phone’s Menu key briefly.

When the display shows Access Internet / Select?, press the OK key to select.

Now hold down the Menu key for about 3 seconds and release.

6. On the Test Set, in the bottom center of the display, the Active Cell box should show:

PDP Active or Transferring; this is required in order to Ping. Note: PDP Active is the same as PDP_Context Active.

7. Press Start Ping (F3) key

8. A correct response looks like the image below. This indicates a functioning IP

connection exists between the Test Set and the phone via the RF link. Note that the response time of the phone is variable.

Page 21 of 32 Rev. 1.2; Feb. 14, 2002

9. Press Stop Ping (F3) key

10. If you started a protocol log, stop it and look at the data.

Pinging an Alternate Device (such as your PC on the LAN)

Note: You cannot log an Alternate Device Ping because the data does NOT travel through the RF link, but only via the LAN. The Protocol Logging feature only captures data that passes over the RF link.

1. Press the Ping Setup (F1) key

2. In the Ping Setup table, set the Device to Ping to Alternate

3. In the Ping Setup table, scroll to Alternate Ping Address, and press the knob.

4. Under Value, enter the PC’s LAN IP Address. Do not enter leading zeros.

5. Press the knob.

6. Press Start Ping (F3) key. It may take a moment for the PC to respond. A correct

response looks like the image below. This indicates a functioning IP connection exists

between the Test Set and the PC.

Product Feature: Data Channel

This is one of the most useful and powerful features of the E6701A. The Test Set acts as a GPRS base station, for connection to one wireless appliance at a time, with complete connectivity through to outside GGSN’s. (A GGSN provides the gateway between the GPRS network and the public packet data network, also known as the Internet). This means you can quickly and easily connect a wireless device to your choice of real Internet websites through a simple LAN connection to the Internet.

You can also perform protocol logging during Data Channel operation. And even though IP data is usually discontinuous, the E6701A allows you to make TX and RX parametric measurements during Data Channel operation.

This tutorial uses a WAP (Wireless Application Protocol) browser built into the phone to show how IP datagrams can be transmitted and received. Data will be exchanged using WML (Wireless Markup Language), which is derived from HTML for wireless device use. Using the phone’s WAP browser, you will connect to a WAP Proxy Gateway program running in your PC. The WAP Gateway program will “pass through” the Internet addresses that you enter into the phone’s browser, and will act as a go-between the phone and the Internet. This tutorial uses the WAPlite Proxy Gateway.

To run the Infinite WAPlite Proxy Gateway software on your PC:

1. On your PC choose Start…Programs.

2. Choose the “WAPLite” directory

3. Select “WAPLite”. A window will appear with multiple tabs.

4. In the WAPLite window, select the “Options” tab

a. If your LAN DOES NOT use a firewall to access the Internet:

i. Check the box next to “Use HTTP Proxy Server” ii. Other boxes on this tab should NOT be checked iii. Type the name of a valid proxy server in the box next to “HTTP Proxy

Server” (You may find the name of your proxy server in Internet Explorer Tools menu. Select Internet Options…Connections…LAN settings…Proxy server. You should also consult your local IT department for this information.)

iv. At the bottom of the tab, if the word “Apply” is in black letters, click the

“Apply” box (if grayed out, skip this step).

b. If your LAN DOES NOT use a firewall to access the Internet:

i. All boxes on this tab should NOT be checked, including “Use HTTP

Proxy Server”

ii. At the bottom of the tab, if the word “Apply” is in black letters, click the

“Apply” box (if in gray letters, skip this step).

5. On the “Stats” tab, click on “Install Service” to turn on the WAP Gateway software in

your PC. With the WAPLite software running on your PC, external devices (like a phone) can access this gateway server via the PC LAN port. The WAPLite server has one set of

Page 23 of 32 Rev. 1.2; Feb. 14, 2002

local “test” data (a logo and some text) provided with the software that can be accessed by an external WAP browser.

To access a simple local file on the WAPLite gateway with the phone:

1. On the Test Set, press the Call Setup key.

2. The device should be on and attached to the Test Set. The phone’s display should show its

browser menu.

Motorola Timeport Example:

The phone’s display should show the Browser Menu. If the Browser Menu is not displayed, press the phone’s Menu key briefly. When the display shows Access Internet/Select?, press the the OK key to select. Now hold down the Menu key for about 3 seconds and release. On the Browser Menu, scroll to 2>Web Favourites with the up/down arrow key. Press the OK key. Scroll to http://local/waplite.wml Press the OK key to GO. (The phone requests data from the device at the address above).

3. Watch the Test Set display.

At the bottom, in the Active Cell window, you can note the status will switch between PDP Active and Transferring as IP datagrams are sent back and forth between the phone and the WAPLite server on the PC.

4. Note the 3 sections of the display:

• Downlink power will flash a result each time the Test Set transmits to the phone.

• Counters track data packets and RACH’s.

• Error Reports continuously indicate the quality of the wireless appliance links.

5. On the device’s display, look at the downloaded image.

Motorola Timeport Example:

Use the scroll up/down key to read the text. If you get a “web server error”, press the phone’s the OK key to go back to see the image, and quickly scroll to see the text. Press the 1 key 2 or 3 times to return to the browser menu. Note: this WAPLite image and text is the only information accessible by a WAP browser that is stored in the Infinite WAPLite gateway at installation.

6. On the PC, note that the Infinite WAPLite window shows one “Active User”, and now lists

some “Requests Processed”.

To browse “real” websites via the WAPLite gateway with the phone:

1. On the Test Set, press the Call Setup key.

2. Make sure the device is attached to the test set.

Motorola Example:

• The Motorola Timeport phone should be on and attached to the Test Set. The

phone’s display should show the Browser Menu.

Appendix B: Troubleshooting

1. If the wireless device will not attach, check that:

1.1. Cable loss is correctly specified in RF IN/OUT Amplitude Offset table

1.2. The SIM is good and installed correctly

1.3. Cell power is sufficient (increase it up to -35dBm to overcome interference, or if an

indirect RF connection is used between the Test Set and phone)

1.4. Try Coding Scheme CS-1. Go to the Call Setup Screen; Call Parms column; Menu 2

of 4 (More key); Coding Scheme (F11 key)

1.5. Maybe the wireless appliance is not capable of multislot configuration operation; if in

doubt, try 1 down 1up. Go to the Call Setup Screen; Call Parms column; Menu 3 of 4 (More key); Multislot Config (F7 key)

1.6. This could relate to a connection parameter called TBF Frame Starting Position.

1.6.1. Change this parameter under call parameters menu 4

1.6.2. Try absolute or immediate frame starting position. The default is relative and

not all mobiles support this.

1.7. Test Set displays IMSI warning:

GSM protocol warning; No IMSI received from MS (Using default IMSI)

1.7.1. This may be an error in the firmware of the phone.

1.7.2. The default IMSI is 001012345678901.

1.7.3. If this message is received, it is not possible to make a data connection unless

a SIM with the default IMSI value is installed in the wireless device.

1.8. If you experience problems establishing a data connection specifically with the BLER

Data Conn Type:

1.8.1. Try changing the setting of the LLC Frame Check Sequence from Valid to

Corrupt. Go to the Call Setup Screen; Call Parms column; Menu 4 of 4 (More key); Connection Parameters (F4 key); scroll in Connection Parameters table to LLC Frame Check Sequence.

1.8.2. Try changing the setting of the BLER Block Polling Interval (default is 32;

range is1 to 32). Go to the Call Setup Screen; Call Parms column; Menu 4 of 4 (More key); Connection Parameters (F4 key); scroll in Connection Parameters table to BLER Block Polling Interval.

2. If BLER mode measurements have problems:

2.1. Attach problem solutions still apply; see 1. Above

2.2. MS must be capable of GMM_INFORMATION messaging.

2.2.1. This is the type of message we use to provoke an ACK/NACK from the

mobile.

2.2.2. If the mobile is not capable of GMM information messaging, then the data

connection will timeout.

2.2.2.1. One possible solution: set the LLC frame check sequence to Corrupt. This

will stop the message getting to GMM and the mobile should still provide the ACK/NACK. Go to the Call Setup Screen; Call Parms column; Menu 4 of 4 (More key); Connection Parameters (F7 key); scroll in the Connection

Page 28 of 32 Rev. 1.2; Feb. 14, 2002

Parameters table to LLC Frame Check Sequence; change the table value to Corrupt.

2.2.3. It is possible that the mobile is capable but GMM is prioritised too low and

the wireless appliance is unable to sustain the link.

2.2.3.1. To get around this we can change the BLER block polling period. This

will allow the mobile to send the ACK/NACK less frequently(one negative result: TX measurements will be slower since the mobile is not transmitting every frame.) Go to call parameters, 1 of 4.

3. ETSI Te st Mode measurements ha ve problems:

3.1. Check that the mobile is capable of the ETSI test mode you would like to use, if not it

will not work

3.2. Check the same parameters as in Attach problems.

If the attach condition is terminated, this may be a Connection

Reconfiguration problem:

4.1. This may be a Connection Reconfiguration problem. When any of the connection

parameters are reconfigured the connection is terminated.

4.2. The mobile likely does not have the PACKET_TIMESLOT_RECONFIGURE

message implemented.

4.2.1. This message is used to change MSTXL, channel, Band, Coding Scheme,

Multislot configuration, and offset P0.

4.2.2. The solution when using the PACKET_TIMESLOT_RECONFIGURE

message is to stop the data connection before changing parameters, then restart the data connection.

4.3. Alternatively, you can change the message used to change parameters to

PACKET_DOWNLINK_ASSIGNMENT; or, for power changes use the PACKET_POWER_AND_TIMING_ADVANCE message. Go to call parameters, 1 of

5. If Internet Explorer cannot access the 8960 Welcome Page:

5.1. Connections:

5.1.1. Check that the LAN cables are good, and are properly connected

5.1.2. If you are using the Test Set’s front panel DATA port: check that the LAN

jumper cable is attached on the Test Set rear panel between the LAN PORT connector and the ETHERNET TO FRONT PANEL connector. (NOTE: For minimum RF interference, Agilent recommends using the rear-panel LAN PORT connector).

5.2. Test Set:

5.2.1. On the System Config Screen, check that the Application is GPRS Lab

Application.

5.2.2. The Test Set LAN IP Address and Subnet Mask should not include leading

zeros.

Example: 111.22.333.44 is correct

111.022.333.044 is incorrect

Page 29 of 32 Rev. 1.2; Feb. 14, 2002

5.3. PC:

5.3.1. Check that the network card (if present) is fully seated in the PC Card slot.

5.3.2. Check that the LAN IP address in the PC is the same as the Test Set’s LAN IP

Address except for the 4th set of numbers (the last 3 digits).

IMPORTANT: Do not set the 4

the 4th set of numbers greater than 254.

set of numbers to 0. Also, do not set

6. The phon e can’t access (browse) real Internet sites

6.1. It can be difficult to “browse” WAP sites or other locations on the Internet because of

firewalls or other restrictions on a specific Intranet. Get help from your Network Administrator.

7. BER measurement errors

7.1. During Data Channel operation, the BER measurement DOES NOT function

correctly.

8. Phone won’t transmit IP datagrams in Data Channel functions

8.1. Some older versions of Motorola Timeport phones may lose the IP address you have

entered. Check this whenever you turn on the phone.

9. When checking the IPCONFIG of your PC, multip le non-zero IP addresses

display

9.1. Use the WINIPCFG utility program to help you troubleshoot.

9.1.1. Choose Windows Start

9.1.2. Select Run

9.1.3. Enter winipcfg, then select OK

9.1.4. Select the Release All button to release the addresses

9.1.5. Select the Renew All button to re-enable the active IP address

9.2. If an old “artifact” IP address is still present in the PC:

9.2.1. You can use a network access program designed to get through a firewall

(such as Nortel Networks Extranet Access Client) to reset the “bad” address.

9.2.2. Start the Extranet program

9.2.3. Use your SecureID card to enter the password and access your network as

normal.

9.2.4. Log off the network

9.2.5. Use the MS-DOS IPCONFIG command, or the WINIPCFG utility to check

that the errant IP address is reset to all zeroes.

10. If you see an “assert message” when you select IP Data (for E6701A

revision A.01.10 only)

10.1. If the Test Set displays an assert message when you set the Data Conn Type to IP

Data, there are two possible solutions:

10.2. To temporarily fix the problem:

10.2.1. Turn the Test Set power off, then on

Page 30 of 32 Rev. 1.2; Feb. 14, 2002

10.2.2. On the System Configuration screen, enter a valid address into the Default

Gateway field

10.3. To permanently fix the problem:

10.3.1. Upgrade the Test Set firmware to a later revision.

10.3.2. This firmware can be obtained from the Agilent website at:
