Agilent E6701A GPRS Lab Application

Demonstration Guide

This demonstration guide outlines how to setup and configure the test set, PC, and a phone. This guide contains two different setups and procedures.

• For a PC connected directly to a test set via a crossover LAN cable:

This procedure is recommended for most demonstrations and allows you to use the phone’s Web browser to access one artificial

Web site.

• For a PC connected indirectly to a test set via an available

Ethernet LAN: This procedure is more complicated. It often requires the network administrator of a local area network

(LAN) to modify the LAN setup to assign addresses for various demo components. If the LAN is configured properly, this procedure allows you to use the phone’s Web browser to access real Web sites.

This guide also demonstrates most of the features of the Agilent E6701A

GPRS lab application.

1.0 Introduction

The Agilent Technologies E6701A lab application (LA) shortens the

GPRS wireless appliance design cycle with a one-box solution for parametric and signaling design validation.

The E6701A 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, an industry-standard product 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 improves 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.

2.3 Product feature:

Screen image capture

To retrieve a copy of the test set’s current screen, go to the 8960 Web control page on your PC and select the Get Image icon.

2.4.1 Using protocol logging

To use protocol logging, from the PC use the 8960 Web control page and select the Protocol Logging icon.

Next, use the Logging Setup icon to select the setup.

Once the image is obtained, clicking the image again will capture a new screen (or refresh the image). Since normal Windows functions are available for the image, you can save the image by right-clicking the image and using the browser’s Save Picture

As… feature. You also can choose a

GIF or bitmap file format. To close the image, click the X in the upperright corner of the window.

Protocol logging

The E6701A GPRS lab application enables the test set to log GPRS protocol messages. The log results are displayed in a Web page format. You control which messages are logged by choosing observation points. It is important to remember these points about the log data:

• you are using the PC to access this data

• the data is formatted to be read by a Web browser (such as Internet

Explorer ® ) on the PC

• you cannot view the log data on the test set’s display

• to save log data, you must store it in the PC’s memory, which you will learn how to do in section

2.4.4 Saving log data in the PC.

• there is only one logging memory location in the test set for log data, of about 4 MB size

• if you select Start Logging again, any previous data in the memory location will be overwritten

• you can log while using any of the data connection types in the test set: IP Data, ETSI A, ETSI B, and

BLER

Change the observation points and buffer operation. (Note: At least one observation point must be selected.)

The observation points correspond to seven protocol layers you can log.

(Refer to Table 1.) Logging data will only be collected for layers that have been selected prior to the start of logging. For this demonstration, select GMM/SM and GSM_L3. Make sure the other observation points are NOT selected.

2.4.2 Buffer operation

1. To demonstrate the buffer operation 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.

2. Next, scroll to the bottom of the page and enter a user comment if desired to annotate the log.

The comment must use alphanumeric characters only and be up to 74 characters in length. Select

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

3. Select the Start Logging icon.

4. Turn on the phone's power to perform a switch-on and attach.

The phone should indicate service signal-strength bars in the upper-left corner of the display within about one minute.

It should also indicate the numbers “001-01” or the word

“Test” in the center of the display. This is the default test network number stored in the test set. On the test set, in the bottom center of the display, the active cell box should show

“Attached”.

5. On the PC, select the Stop

Logging icon. Note that no data will be displayed until the log is stopped. The test set has captured the log data in its internal memory.

2.4.3 Examining log data on the PC

Look in the PC’s upper window using the scroll bar to see the message summary. If you click on one of the message summaries, a hyperlink will launch in the lower window to show you the detail for that message.

Look in the lower window using the scroll bar to see the message details.

Notice the time stamp and message number at the front of each message. Refer to the E6701A Lab

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.

2.5.1 Protocol logging while pinging

The ability to make a protocol log while performing a ping to a DUT

(phone) is a valuable feature. This feature is performed as follows:

1. On the test set, go to the Call

Setup screen.

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. (Ignore any GPRS data connection errors.)

13. Press Stop Ping (F3) key.

14. If you started a protocol log, stop it, then look at the data on the PC.


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 GGSNs. A GGSN provides the gateway between the GPRS network and the public packet data network such as the internet. This means you can quickly and easily connect a wireless device to your choice of real Internet Web sites through a simple LAN connection to the Internet.

You can also perform protocol logging during data channel operation.

Even though IP data is usually discontinuous, the E6701A allows you to make TX and RX parametric measurements during data channel operation.

This demonstration uses a Wireless

Application Protocol (WAP) 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 standalone WAP proxy gateway program running on your

PC.

2.6.1 Running gateway software

To run the infinite WAPLite proxy gateway software on your PC:

1. Choose Start.

2. Choose Programs.

3. Choose the WAPLite directory

4. Select WAPLite. In the window with multiple tabs, select

Options.

5. The box next to Use HTTP Proxy

Server should NOT be checked; additionally, other boxes on this tab should NOT be checked.

6. At the bottom of the tab, if the word “Apply” is in black letters, click the Apply box. If “Apply” is in gray letters, skip this step.

7. On the Stats tab, click on Install

Service to turn on the WAP

Gateway software on your PC.

With the WAPLite software running on your PC, external devices can access this gateway server via the

PC LAN port. The WAPLite server has one set of test data (a logo and some text) provided with the software that can be accessed by an external WAP browser, which is designed into most GPRS phones.

2.6.2 Browsing the gateway

To browse the WAPLite gateway with the phone:

1. On the test set, press the Call

Setup key. Note: The Motorola

Timeport phone should be on and attached to the test set.

Menu key briefly.


Internet/Select?” press the OK key to select.


5. On the Browser menu, scroll to

2>Web Favorites with the up/down arrow key and press

OK.

6. Scroll to http://local/waplite.wml and press OK. (The phone requests data from the device at the address above.)

Watch the test set display. At the bottom, in the active cell window, you can note the status will switch between “PDP active” and “transfer-

ring” as IP datagrams are sent back and forth between the phone and the WAPLite server on the PC.

Note the three sections of the display: a. downlink power will flash each time the test set transmits to the phone b. counters track data packets and

RACHs c. error reports continuously indicate the quality of the wireless appliance links. The

BLER is measured using the

Agilent-patented ACK/NACK method.

7. On the phone’s display, look at the downloaded image and use the scroll up/down key to read the text. If you get a web server error, press the phone’s OK button to go Back to see the image, and quickly scroll to see the text. (There appears to be a bug in the WAPLite data download in some versions.)

8. Press the C key three 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. On the PC, note that the

Infinite WAPLite window shows one active user, and lists some requests processed.

2.6.3 Logging datagrams while browsing

During a log of IP datagram while you are browsing the WAPLite gateway with the phone, the LAN cable will carry IP datagrams between the phone and the WAP gateway software running on the PC.

Simultaneously, the same LAN cable will carry the protocol logging data between the test set and the Internet

Explorer software running on the

PC.

1. On the PC, go to the active

Internet Explorer browser with the 8960 web control page and select Logging Setup to change the observation points.

2. Select IP (only) and OK.


4. On the phone, on the Browser menu, scroll to 2>Web

Favorites with the up/down arrow key, then press OK.

5. Scroll to http://local/waplite.wml and press OK to Go. The phone requests data from the device at the address above. Watch the test set's display as the active cell window switches between

Protocol logging

The E6701A GPRS lab application enables the test set to log GPRS protocol messages. The log results are displayed in a web page format. You control which messages are logged by choosing observation points. Here are some important points about the log data.

• You are using the PC to access this data.

• The data is formatted to be read by a web browser, such as

Internet Explorer, in the PC.

Note: You cannot view the log data on the test set’s display.

• To save this log data, you must store it in the PC’s memory, which you will learn to do in section 3.4.3).

• There is only one logging memory location in the test set for log data, which holds about

4 MB.

• If you select Start Logging again, any previous data in the memory location will be overwritten.

• You can log while using any of the data connection types in the test set: IP Data, ETSI A,

ETSI B, or BLER.

1. On the PC, on the 8960 Web control page, select the

Protocol Logging icon.

2. Select Logging Setup.

3. Change the observation points and buffer operation. At least one observation point must be

selected. For this demonstration, select GMM/SM and GSM_L3 and make sure the other observation points are NOT selected.

As shown in Table 2, 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.

Logging softkey (F1). Wait a few moments. The PC display will update as new data is captured in the test set.


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.

The ability to make a protocol log while performing a ping to a DUT is a valuable feature. (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 left Control column of softkeys, press the More key until you see “2 of 2”.

3. Press the Ping (F3) key.

3.5.1 Pinging the alternate device

When pinging an alternate device, such as the PC on the LAN, it's important to note that you cannot log an alternate device ping because the data does NOT travel through the RF link, but only via the LAN.

3.5.2 Pinging the DUT

When pinging a DUT such as a phone or other type of wireless appliance, it's important to note that you can log a DUT Ping because the data travels through the RF link. Set the observation point to IP, start logging, and 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. Because it may take a phone over five seconds to respond, set the

Ping Timeout Value to ten

(seconds).

3. Verify that the test set's active cell field indicates “Attached”.

4. Press the phone’s Menu key briefly.

5. When the display shows

“Access Internet / Select?”, press the OK key to select.

6. Hold down the Menu key for about three seconds and release. 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 the Start Ping (F3) key. A correct response looks like the image above. 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. (Ignore any GPRS data connection errors.) If the

DUT does not respond, try turning the phone off, then back on and then repeat steps 4 through 7.

8. Press the Stop Ping (F3) key. If you started a protocol log, stop it and look at the data.


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 such as the Internet). This means you can quickly and easily connect a wireless device to your choice of real

Internet Web sites 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 demonstration uses a WAP browser built into the phone to show how IP datagrams can be transmitted and received. Data will be exchanged using WML, 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 for data between the phone and the

Internet.

3.6.1 Running the Infinite WAPLite proxy gateway software on a PC

1. Choose Start on your PC.

2. Choose Programs.

3. Choose the WAPLite directory.

Internet, check the box next to

“Use HTTP Proxy Server”.

Other boxes on this tab should

NOT be checked.

6. Type the name of a valid proxy server in the box next to “HTTP

Proxy Server:”. For this Agilent demonstration, use webproxy.cos.agilent.com: 8088.

7. At the bottom of the tab, if the word “Apply” is in black letters, click the Apply box (if “Apply” is in gray letters, skip to step 9 below.

8. If your LAN DOES NOT use a firewall to access the Internet, un-check the box next to “Use

HTTP Proxy Server”. Other boxes on this tab should NOT be checked. At the bottom of the tab, if the word “Apply” is in black letters, click the Apply box (if “Apply” is in gray letters, skip this step).

9. On the Stats tab, click on

Install Service to turn on the

WAP gateway software on your

PC.

With the WAPLite software running on your PC, external devices, such as a phone, can access this gateway server via the PC LAN port. The

WAPLite server has one set of local

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

Problem could relate to a connection parameter called TBF

Frame Starting Position. Change this parameter under call parameters menu 4. Try an Absolute or Immediate frame starting position. The default is Relative and not all mobiles support this.

Test set displays IMSI warning: GSM protocol warning;

No IMSI received from MS (using default IMSI)

This is often an error in the firmware of the phone. The default IMSI is 001012345678901. This is the IMSI programmed into Agilent or HP test SIM’s.

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.

Problems establishing a data connection specifically with the BLER Data Conn Type:

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.

Try changing the setting of the BLER Block Polling Interval

(default is 1; range is 1 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.

Problem Potential resolutions

BLER (Data Connection Type) measurements have Problem solutions noted above for Attach apply.

problems

Ensure the MS is capable of GMM_INFORMATION messaging. This is the type of message sent by the test set to provoke an ACK/NACK from the mobile. If the mobile is not capable of GMM information messaging, then the data connection will timeout.

ETSI Test Mode measurements have problems

The Attach condition terminates prematurely

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 Parameters table to LLC Frame Check

Sequence; change the table value to Corrupt.

It is possible that the mobile is capable of GMM messaging but GMM is prioritized too low and the wireless appliance is unable to sustain the link.

One solution is to change the BLER Block Polling Interval.

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; 4 of 4; Connection Parameters table.

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

Check the same parameters as in "wireless appliance will not attach" above.

This may be a connection reconfiguration problem. When any of the connection parameters are reconfigured the connection is terminated.

The mobile likely does not have the

PACKET_TIMESLOT_RECONFIGURE message implemented.

This message is used to change MSTXL, channel, Band,

Coding Scheme, Multislot configuration, and offset P0.

The solution when using the PACKET_TIMESLOT_RECON

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

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 4.

If an old “artifact” IP address is still present in the PC, 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 as follows: Start the Extranet program. Use your SecureID card to enter the password and access your network as normal. Log off the network. Use the

MS-DOS IPCONFIG command, or the WINIPCFG utility to check that the errant IP address is reset to all zeroes.

If the Test Set displays an assert message when you set the

Data Conn Type to IP Data, there are two possible solutions:

To temporarily fix the problem, turn the test set power off, then on. On the System Configuration screen, enter a valid address into the Default Gateway field.

To permanently fix the problem, upgrade the test set's firmware to a later revision. This firmware can be obtained from the Agilent website at: www.agilent.com/find/8960support
