3.10.1HSDPA or GPRS Data Transfer via Siemens Wireless Ethernet

Figures

1 Introduction

HC15 is the first Siemens wireless module to offer UMTS and GSM capability on the same device. The benefit is that the HC15 includes HSDPA capability in a UMTS network and also all common mobile connectivity features like voice, short messages, GPRS and EGPRS.

The HC15 modules need to connect to an adequate host device, such as the Evaluation Board DSB75. Designed to help application manufacturers and system integrators to test and develop their HC15 host application, the DSB75 provides all interfaces and peripherals needed to run the HC15.

The purpose of this document is to guide you through the process of connecting the hardware, installing the software on a Windows XP system, and, last but not least, making the first data transmission via UMTS and HSDPA.

2.5Installed Devices and Tools

After successful installation, the devices listed below are available. Under Windows XP, you can use the Device Manager to check that all components are properly installed and configured.

Siemens HSDPA USB Modem

???AT command and data interface, also referred to as ???Modem??? port if queried using the AT^SQPORT command.

???Intended particularly for HSDPA and GPRS data connections.

???The virtual COM port Windows has assigned to the AT command and data interface is listed in the Device Manager under Modems.

???The port number can be gathered from Control Panel | Phone and Modem Options. This COM port can be used to set up dial-up network connections. The bit rate set by default on the Modem property page is not relevant for USB and can be left unchanged. On the Advanced tab you can put the command string used to define the PDP context for your

GPRS / HSDPA provider. See also Chapter 3.7.

Siemens USB Com Port

???AT command interface, also referred to as ???Application??? port if queried using the AT^SQPORT command.

???Mainly intended for controlling the HC15 module, for receiving URCs, can be used also for sending, receiving, writing and reading short messages. Not intended as data interface for HSDPA and GPRS.

???The virtual COM port Windows has assigned to this port is listed in the Device Manager under Ports (COM&LPT).

Siemens Wireless Ethernet Adapter

???Wireless network adapter intended for HSDPA and GPRS data connections.

???Listed in the Device Manager under Network adapters.

???Software controlled by the Siemens Connection Manager. To open the program in Windows XP, click Start, point to Programs, select Siemens, select HSDPA USB Modem and click Connection Manager. See chapters 3.10 and 3.10.1 for details of how to set up a connection.

2.6Uninstalling Drivers and the Connection Manager

Select Control Panel -> Add or Remove Programs and Connection Manager

Press Remove to select the uninstaller of the Connection Manager and the HC15 drivers.

Please press Yes to start the uninstaller.

The Connection Manager and all HC15 drivers will be removed.

2.7Uninstalling Drivers and Tools from Earlier HC15 Releases

The following procedures apply only to drivers of earlier HC15 releases supplied as preview samples for testing only.

2.7.1Uninstalling Earlier Drivers

Under Windows XP, open the Device Manager and select the drivers as described in chapter 2.5. Keep in mind that the drivers are listed in the Device Manager only when the module is switched on. Right-click the driver and, from the resulting menu, select Uninstall.

2.7.2Uninstalling Earlier Connection Manager

Old versions of the Siemens Connection Manager were installed in Windows XP under

Program Files | Siemens | ConnectionManager. To uninstall the program simply remove the ???conman.exe??? file.

3 Using the HC15 Module

The following examples show the basic steps required to register to the network, to select UMTS mode or GSM mode and to attach to HSDPA or GPRS.

The examples are based on a UICC card provisioned by the German network operator T- Mobile. The used UICC card is capable of UMTS and GSM and enables the subscriber to switch back and forth between both networks.

3.1AT Command Interpreter

AT commands can be entered on two interfaces of the HC15 module:

???Siemens HSDPA USB Com Port

???Siemens HSDPA USB Modem

Yet, we recommend that the Siemens HSDPA USB Com Port be used for controlling the HC15 module, eg. for entering AT commands and receiving URCs, while the Siemens HSDPA USB Modem is mainly intended for use as a modem. For greater detail refer to [1], especially the chapters ???AT Command Interpreter??? and ???Unsolicited Result Code Presentation???.

As described in Chapter 2.5, each interface is assigned a virtual COM port of its own, which enables accessing the interface from the host application or, accordingly, the dial-up connection. To easily identify both interfaces you can use the AT^SQPORT command:

If you need to operate the HC15 from both interfaces at a time, bear in mind that both are handled by the same AT command interpreter. As a result, AT commands entered on both interfaces are not executed in parallel but sequentially, one after the other. So, an AT command issued on one interface will be buffered on this interface to be executed after the other interface has completed processing earlier AT command(s). The buffered command string is not echoed, but will be indicated when executed.

3.2Switching on the HC15

The HC15 can be started by pressing the IGT key of the DSB75. Please wait approximately 2 seconds before using the module, for example before entering AT commands.

Disconnecting and plugging the USB cable during operation is not supported.

3.3Switching off the HC15

To shut down the HC15 module, enter the AT^SMSO command. This enables the ME to save all data and perform an orderly shutdown.

The HC15 module can also be switched off by using the IGT line as described in [1] (see AT^SCFG) and [1] (see section ???Configuring the IGT Line for Use as ON/OFF Switch???).

3.4Registering to the Network

Make sure to operate the HC15 always with the UICC card inserted in the DSB75 card reader and a valid SIM PIN entered. This is because most AT commands require SIM PIN authentication.

Write command: AT+CPIN=<pin>[, <new pin>]

3.5Selecting UMTS or GSM

The GSM 07.07 operator selection command AT+COPS has been enhanced to enable the subscriber to select whether to use UMTS or GSM. You can quickly switch back and forth between both network types while the ME remains registered.

Write command: AT+COPS=<mode>[, <format>[, <oper>[, <act>]]]

The parameter <act> (access technology) can take the values listed below. The parameter is stored non-volatile.

0 GSM network

2 UMTS network

Note: By factory default, an automatic network selection mode is set which enables the ME to select either UMTS or GSM, depending on the network coverage. This automatic mode remains enabled until you explicitly set either UMTS or GSM using the <act> parameter of AT+COPS. Setting the <act> parameter forces the ME to select either UMTS only or accordingly, GSM only. If the specified network is not available, the network registration will be disabled.

OK

Furthermore, the command AT+COPS serves to query or specify several modes of selecting the GSM network operator. These functions are not discussed in this document.

3.6Attaching to the HSDPA or GPRS Network

After PIN authentication, the HC15 module automatically tries to attach to the HSDPA or, accordingly, GPRS network.

3.7Defining the PDP Context

Use the AT+CGDCONT command to configure the correct provider settings. The PDP context is stored non-volatile.

Write command:

AT+CGDCONT=<cid>[, <PDP_type>[, <APN>[, <PDP_addr>]]]

The focus of this document is only on the parameters <cid>, <PDP_type> and <APN>. The string parameters must be enclosed in quotation marks.

Under Windows XP, the PDP context can, optionally, be entered on the Modem property page as described in Chapter 2.5.

3.8Making a Voice Call (MO)

The commonly used GSM 07.07 dialing command ATD is fully applicable both in the UMTS and the GSM network.

To make a mobile originated voice call enter ATD, type the destination number and add a semicolon. The result code OK will be returned immediately after dialing, prior to call setup.

To end the call, use the AT+CHUP command (ATH is for data calls only).

3.9Answering a Voice Call (MT)

A mobile terminated voice call is indicated by the RING URC. To answer the call, enter ATA.

To terminate the call use AT+CHUP.

3.10HSDPA or GPRS Data Transfer

HC15 offers two alternatives to access the GPRS or HSDPA networks:

???The Siemens Connection Manager provided for the Siemens Wireless Ethernet Adapter

See chapter 3.10.1.

???A dial-up network connection via the installed Siemens HSDPA Modem as described in chapter 3.10.2.

In either case the ME must be registered to the network. So, before trying to connect to the data services ensure that SIM PIN authentication was done from the host application. To take advantage of HSDPA make sure that the <act> parameter of AT+COPS equals ???2???. For GPRS the parameter shall be ???0???. It is recommended to configure these settings on the

Siemens HSDPA USB Com Port.

3.10.1HSDPA or GPRS Data Transfer via Siemens Wireless Ethernet Adapter

The easiest way is using the Siemens Connection Manager installed along with the HC15 driver package.

???To open the tool in Windows XP, click Start, point to Programs, select Siemens, select

HSDPA USB Modem and click Connection Manager.

???Use the Select Device listbox to choose the Siemens Wireless Ethernet Adapter. When opened the first time or after disabling the adapter, the listbox may be empty.

???Check the APN Name box and enter the APN (Access Point Name) of your service provider.

???If necessary, check the

Authentication Preference box and select the type of authentication protocol. Otherwise, PAP and CHAP apply by default. Username and password are also provider dependent.

???Press the Connect button to set up a connection. Then simply open your Internet browser. The box on the rightmost bottom represents the signal strength.

???To close the connection press the

Disconnect button (available when connected).

The Auto Connect check box on the leftmost bottom can be activated if you want the Siemens Wireless Ethernet Adapter to automatically connect to the network each time you restart the HC15. This option can be used particularly with a flat rate subscription. In this case, take care that the SIM PIN authentication is also done automatically.

3.10.2HSDPA or GPRS Data Transfer via Dial-Up Network

Before dialing, make sure that the virtual COM port is not used by any application (eg. by a terminal program or by the host application).

Also, ensure that you have the PDP context for your service provider defined by using the AT+CGDCONT command. The command string can be entered either on the Modem property page on the Windows Control Panel or in the host application (see Chapters 2.5 and 3.7).

From to the Control Panel, choose Network Connections and select the dial-up connection created for HC15. (Instructions on how to create a new dialup connection can be found in chapter 4.1)

The correct dial string *99***1# should already be given, if entered in the Phone number box when the dial-up connection was added. Otherwise, you can type the number here before dialing.

User name and password may or may not be required, depending on the network operator.

The connection is properly established when the following messages are reported:

To verify the data rates for up- and/or downlink, you can use, for example, the file download status dialog of your Internet browser.

Terminating the dial-up connection

To stop a HSDPA or GPRS data connection disconnect the dial-up connection. This can be done in two ways:

1.Double-click the dial-up network connection icon in the system tray. In the resulting connection status dialog press the Disconnect button.

2.The other way is available on the Network Connections page of the Control Panel: Right- click the active connection to open a context menu where to choose Disconnect.

Note that when you close the dial-up connection the echo will be automatically deactivated and needs to be activated again in the application.

4 Appendix I

4.1Adding and Configuring a New Dial-Up Connection

This chapter describes how to create and configure a new dial-up connection when using the installed Siemens HSDPA USB Modem to access the GPRS or HSDPA network:

4.1.1Adding a New Dial-up Connection

Open the Control Panel, double-click Network Connections, select Create a new connection on the left side of the panel.

The Network Connection Wizard opens. Click Next to continue. Put a check mark on

Connect to the Internet and click Next.

Select the option Set up my connection manually and click Next. Select Connect using a dial-up modem and click Next.

Select the modem driver that you want to use for the dial-up connection. Click Next to continue. Type an appropriate Connection name and click Next.

In the Phone number box, put the dial string *99***1# commonly used to access the GPRS network.

Note: The number ???1??? added before the hash determines that the first PDP context shall be used. The number must be identical to the <cid> value set with AT+CGDCONT (see Chapter 3.7)

Depending on the network, you may be required to put a User name and a Password for the dial-up connection. If not required, you may leave all boxes empty. Click Next and, in the resulting dialog, click Finish.

This will cause the Connect??? dialog to appear (screen is shown in Chapter 4.1.2). Yet, at this moment, it is recommended that you press Cancel in order to check, and if necessary, to configure the dial-up connection as described in Chapter 4.1.2.

4.1.2Configuring a Dial-up Connection

Every newly created dial-up connection should be configured before using it to establish a PPP connection.

Open the Control Panel, double-click Network Connections, select the dial-up connection you want to configure. In the resulting Connect??? dialog, press the Properties button.

On the General tab, select the modem you want to configure. The correct dial string *99***1# should already be given, if entered before in the Phone number box when the dial-up connection was added (see Chapter 4.1.1).

Select the Security tab to verify or edit authentication options for PPP connections.

By default, MS Windows XP enables the option Typical with unsecured passwords for the commonly used but unsafe PAP authentication method. As this is the minimum level of security supported in all networks the setting usually enables the subscriber to make a connection, though at the expense of security.

Many network operators apply more secure authentication methods for PPP connections, such as CHAP. For access to these networks, activate the Advanced (custom setting) option and press the Settings button. On the resulting Advanced Security Settings property page, enable / disable the authentication protocols according to the information provisioned by your service provider.

Note: If an attempt to connect to a HSDPA or GPRS network fails, check that the authentication protocols are properly set.

On the Networking tab, the default settings are acceptable in most cases: The drop-down menu shows PPP: Windows 95/98/NT/2000, Internet for the type of dialup server as default.

In the PPP settings box, verify that Enable LCP extensions, Enable software compression are selected and click OK.

Select the Internet Protocol (TCP/IP) on the Networking tab and press the Properties button to go to the General page:

In most cases, it is sufficient to accept the default settings:

Obtain an IP address automatically and

Obtain DNS server address automatically.

Otherwise, you have to select the options

Use the following IP address / Use the following DNS addresses and specify the IP addresses provisioned by your network operator.

The Advanced button opens a further property page where you can set your preferences when working in a local network and a dial-up network at the same time.
