Bluetooth wireless technology
Using a high speed radio link, Bluetooth wireless technology eliminates the need for cables for connecting the phone to handheld devices,
accessories and laptops. It provides secure short-range communication
without cables – even without line of sight between the devices.
Bluetooth wireless technology can be used for synchronization with
laptops and PDAs, for wireless headset, for turning the phone into a
wireless modem, for exchanging calendar events and business cards
with other phones, and more.
Synchronization

Synchronization with PCs, a Personal Digital Assistant (PDA) or calendar is effortless. Appointments and tasks in the phone’s calendar and
entries in the phone book can be synchronized via Bluetooth connection, infrared or a cable, and also via WAP using SyncML. The T39
features a hierarchical phone book in which you can store contact
details.

Secure WAP

Internet browsing and secure mobile services are supported over Wireless Application Protocol, WAP. The built-in browser supports WAP
June2000 (WAP 1.2.1) with push services and secure transaction methods, such as digital signatures. Depending on network services, the
T39 provides WAP over GPRS with constant connection, GSM Data or
SMS.

High speed and GPRS The T39 enables high speed data communication and WAP browsing
with a constant connection, as required by the application. In GSM
Data connections, High Speed Data supports a high transmission rate,
and a fast download speed. Furthermore, by supporting General Packet
Radio Services (GPRS) networks, the T39 is designed to remain
“always-online” with a cost efficient IP connection which enables
rapid data transmission.

for operators to provide new services to existing users over the air, including new menus and
functions in the phone. Support for mobile positioning enables the design and implementation of new productivity and commercial solutions.

BLUETOOTHTM WIRELESS TECHNOLOGY
The T39 has built-in Bluetooth wireless technology. Short-range radio links operate in a globally available 2.4 GHz radio frequency band, and ensures fast and secure communications up
to a range of 10 metres (typically) between devices. Please note that in countries where the use
of Bluetooth wireless technology is not allowed, you must ensure that the Bluetooth function is
set to off. Contact the Ericsson representative to check if the use of Bluetooth wireless technology is restricted in your country.
Bluetooth wireless technology is designed to be fully functional even in very noisy radio frequency environments and it provides a high transmission rate. All data transfer is protected by
advanced error-correction methods that ensure a high level of data security.
Bluetooth wireless technology facilitates instant connections which are maintained even when
the devices are not within line of sight. Bluetooth wireless technology facilitates high-quality
voice transmissions, even under severe conditions. For example, you can connect your headset
to your mobile phone to keep your hands free for more important tasks.
Ericsson is a founding partner of the Bluetooth Special Interest Group (SIG). Bluetooth wireless
technology devices that are expected to be available in the near future, include:
•

Headset for wireless voice transmission and remote call control

•

PCs, laptops, PDAs, palmpads for data transfer, synchronization etc.

Using Bluetooth Wireless Technology In The T39
The built-in Bluetooth wireless technology allows a very fast data transfer speed, when one or
more Bluetooth devices is within a range of 10 metres. For example, the services available via
infrared communication are replaced by Bluetooth wireless technology communication, and
with a better performance. Key benefits of using Bluetooth wireless technology in the T39 are:
Replace cable and infrared
Bluetooth wireless technology gives a true wireless connection to
headset, computers, networks, printers and other devices.
Several devices

The T39 identifies and maintains several devices in a pairing list.

Radio link

No line of sight required; the phone can remain in a briefcase or in a
pocket, as long as no solid objects are in between (whereas infrared
requires line of sight).

Secure data connection A Bluetooth wireless technology PC/laptop can connect to the phone,
turning it into a modem for accessing the internet and for data transfer,
via GSM Data or via General Packet Radio Services (GPRS).
Synchronization

Fast synchronization, even without line of sight, of calendar and phone
book with PC/laptop, PDA and quick exchange of business cards, calendar events and melodies with other phones and devices.

Phone management

Manage the phone book and the phone settings from a Bluetooth PC.

Print from the phone

When connected to a printer via Bluetooth wireless technology, the
user can print items directly from the phone. Items that can be printed
include overviews in the calendar, appointments and tasks, contacts,
business cards and text messages.

GENERAL PACKET RADIO SERVICES
The introduction of GPRS (General Packet Radio Services) is one of the key steps in the evolution of today’s GSM networks to enhance the capabilities for data communication. Data traffic
is increasing enormously over both wired and wireless networks. This growth in demand for
internet access and services has paralleled the explosion in demand for mobile communications.
Users want access to the internet while they are away from their offices and homes. The main
applications driving the wireless internet development are e-mail access, web browsing and pull
content, also known as web clipping. User surveys have found that a vast majority of executives
and business professionals want wireless internet access to both send and receive e-mail on a
portable device, as well as web browsing with both text and graphic capabilities! The demand
for high-speed internet access will be the key driver for coming generations of wireless services
equal to, or faster than wired, and GPRS can deliver this mobile internet functionality. GPRS
will allow innovative services to be created, enabling new and previously inaccessible market
segments to be addressed, increasing customer loyalty and reducing churn. Machine-to-machine
and person-to-machine communications will become possible.
GPRS applications can be developed both as horizontal and vertical applications. Vertical applications can for example be operations like police and emergency, taxi, delivery or automated
services such as vending machines, supervision, vehicle tracking. Horizontal applications are
generic, such as internet access, e-mail, messaging, e-commerce and entertainment. One of the
advantages with GPRS is that it will profit from the global coverage of existing GSM networks.
Therefore applications developed for GPRS can be deployed on a large scale and will gain
economies of scale. GPRS also provides an ideal secure medium for connections to private networks, banking and financial services.
The T39 supports GPRS, which means that the data is sent in packages at a very high speed. The
phone remains connected to the network all the time without using any transmission capacity,
until data needs to be sent or received. This illustration gives a comparison.

•1. A normal GSM call only uses one of eight repeating time slots in the GSM channel, giving a
data speed of 9,600 bps. The T39 supports a more efficient coding scheme, giving data
speeds of up to 14,400 bps (providing the network supports this). Furthermore, High Speed
Circuit Switched Data (HSCSD) gives the possibility to use two time slots for receiving
data. This can increase the data speed up to 28,800 bps (network-dependent)
•2. In GPRS, data is sent in packets, and up to three time slots can be combined to provide the
necessary bandwidth, up to 39,600 bps for receiving data, depending on coding scheme

Using GPRS In The T39
Instead of occupying a whole voice channel for the duration of the call, data is sent in small
packets as needed, just like IP on the internet. Capacity is used only when data is being sent or
received, which means that it is possible to be “constantly” connected, as required by the application in use. If the user wants to send e-mail, it may be sufficient to share a channel with several other users. On the other hand, the phone has access to several time slots if a higher
capacity is needed.
The GPRS specification includes four coding schemes with different data speeds. The T39
works with the first two coding schemes, but the data speed will naturally vary according to network configuration.
The GSM system's design limits the ability to use all eight time slots. Instead, the T39 uses up to
three time slots for receiving data, and one slot for transmitting. This means the speed for
receiving data is up to 39,600 bps and for sending data up to 13,200 bps.
Information about the identity of phone and the characteristics of the connection are described
in the PDP context (Packet Data Protocol context). This information is stored both in the phone
and in the mobile network, so that each phone is identified and “visible” to the system. In T39,
multiple PDP context settings can be set via the menu system, or by OTA provisioning.
Using GPRS with the T39 gives several advantages, for example:
Constant connection

Keep an open connection to the e-mail system or the company network, staying online to receive and send messages at all times. All connection settings can be managed by using the Data connections feature.

High speed

Gain access automatically to increased bandwidth when downloading
large files, images etc.

Cost efficient

GPRS being an IP-based connection means that a high transmission
capacity is only used when needed. This makes it possible to stay connected via GPRS, whereas keeping a constant circuit switched connection would be more expensive.

WAP over GPRS

Access the internet via WAP at high speed and with a constant connection. The user can run the WAP functions such as browsing.

E-mail over GPRS

This means that the user can be connected to the e-mail system while
reading and preparing messages, and that the messages are sent at a
high speed.

Data communication

Using GPRS, this provides data and internet/Intranet access, for a PC,
PDA or handheld device connected via Bluetooth wireless technology,
infrared or cable.

Data and voice

The T39 can maintain a data connection when conducting a voice call.
For example, the user can conduct voice calls while maintaining an
uninterrupted connection to an e-mail system.

Provide settings

The GPRS configuration settings can be sent from the provider over
the air, OTA. This way, the user can use GPRS without making any settings in the phone.

User controlled settings Full user control is enabled in the T39. In the Data connections menu,
the user can set up multiple descriptions and access advanced settings
for GPRS, for example Data compression and Quality of Service.

WAP SERVICES
The typical WAP client is a small, portable device which is connected to a wireless network.
This includes mobile phones, pagers, smart phones, PDAs and other small devices. In these
devices, you have a limited user interface, low memory and computing power compared to
desktop and laptop computers.
The WAP browser in the T39 is compliant with WAP June2000 (WAP 1.2.1) includes WTLS
class 3 and mechanisms for digital signatures. It is designed for WML and cannot read ordinary
HTML pages, but it is suitable for interaction with customer services, e.g. ticket reservation. It
is also handy when you want to access text-based information, such as timetables, share prices
and exchange rates and internet banking and other interactive services.

Using WAP In The T39
The built-in WAP browser gives the user portable, fast and secure access to a wide variety of
services, with the possibility of personalized services. WAP in the T39 offers new opportunities
to companies and service providers:
Push service

A useful feature for companies and service providers to push contents
or service indications to work groups or customers. This is used for
notifications, mail alerts, messaging, news, stock quotes, contacts,
meeting requests, games etc.

Provide settings

Using SMS message, configuration settings can be sent over the air,
OTA, so that the user does not need to configure the WAP access settings manually. WAP settings may also be customized by the operator.

Adapt to phone type

When creating a WAP service, you want to make sure that the user
experience is what you intended, regardless of client device type. The
function User Agent Profile is supported by the T39 to allow the contents to be automatically optimized for the phone.

Security

Service providers can offer commercial and business critical services
with high security to mobile users, compliant with Wireless Transport
Layer Security (WTLS) class 1, 2 and 3. Digital signatures and Wireless Identification Module (WIM) are supported in the T39. The WIM
is used to store security related information.

Several bearer types

The T39 accesses WAP over a standard GSM Data connection as well
as over a GPRS connection. SMS is available as bearer type also. (Network-dependent services.)

Bandwidth efficiency

One of the key advantages WAP has over text-based HTML pages on
mobile devices, is the bandwidth efficiency for communication. This is
due partly to the fact that the WAP application is communicated to the
wireless devices in the form of binary encoded data. Over a GPRS connection, bandwidth is used even more efficiently. See “Using GPRS In
The T39” on page 11.

Easy create for WAP

Creating a WAP service is no harder than creating an Intranet/internet
service today since WML and WMLScript are based on well-known
internet technology. New market segments can be addressed by
launching innovative mobile Value Added Services.

Using standard tools

It is possible for the service creator to use standard tools like ASP or
CGI to generate content dynamically. You can utilize existing investments in databases etc. that are the basis of existing internet services.
Create a service once and make it accessible on a broad range of wireless networks.

Maintain customer base You can adapt existing internet services to WAP. The actual binary
encoding can be handled by the WAP Gateway which makes it possible
to create WAP applications using the text-based language WML and
other tools. In fact, existing HTML-based applications on the internet
can be viewed in the WAP browser, if an automatic conversion is performed in the WAP Gateway.
Improve productivity

Improve and simplify the communication flow within an organization
by making information available to mobile users. A company or organization can use a WAP gateway to provide a secure connection to the
company network for their users.

The WAP profiles

The T39 holds five WAP profiles, each with a group of network settings and a home page. If you provide a corporate WAP service on your
Intranet, it is useful to enter an Intranet WAP profile in user phones.
The WAP profile holds network settings and user identification. The
users switch easily between the corporate services and WAP services
on the internet, simply by switching WAP profile.

Bearer Type Characteristics
The phone accesses WAP services over SMS or IP, where IP can be provided either over GSM
Data or GPRS depending on network services.
Typical differences which distinguish the bearer types are listed below.

GPRS Access
•

The connection is maintained “constantly”, as required by the application, and data is transmitted in packets. This means that the phone is connected almost all the time without using
network capacity.

•

Higher transmission speed than with GSM Data and SMS access.

•

Pricing of GPRS can be dependent on the actual use of bandwidth, which means very low
cost when no data is sent or received, while the phone remains connected to the WAP service.

•

When transmitting large amounts of data, bandwidth can be increased automatically to allow
faster transmission speed.

•

GPRS is ideal for Complex Pull services, Browsing, Data transfer, Provisioning, Pager service, Messaging services, Info services, Push initiations.

GSM Data Access
•

Circuit connection of data call which means that the phone is connected during the entire
WAP session.

•

Comparably higher transmission speed than with SMS access.

•

Pricing of GSM Data access can be compared to pricing of data calls in the network.

•

GSM Data is suitable for Complex Pull services, Browsing and Data transfer.

•

GSM Data is not suitable for Provisioning, Pager service.

SMS Access
•

SMS point-to-point is used and not SMS Cell Broadcast.

•

The connection is maintained by the automatic exchange of ”messages” between the phone
and the SMS Service Center.

•

Comparably lower transmission speed than with GSM Data access.

•

Pricing of SMS access can be compared to pricing of the normal SMS service in the network.

•

SMS is suitable for Messaging services, Info services, Push initiations, Provisioning.

•

SMS is not suitable for Browsing, Data transfer.

Gateway Characteristics
The WAP Gateway provides services in the company’s Intranet, a banking or stock trading service on the internet, or access to other WAP applications on web addresses anywhere on the
internet. A Gateway is identified by an IP number or by a phone number, depending on access
type.

Security Using WAP
When using certain WAP services the user may want a secure connection between the phone
and the WAP gateway, for example when using banking services. An icon in the display indicates when a secure connection is used. The T39 is based on the WAP June2000 (WAP 1.2.1)
specifications where security functionality is specified with a technology called Wireless Transport Layer Security (WTLS).
The WAP protocols that handle the connection, its transport and its security are structured in
protocol layers. The security is handled by the WTLS layer operating above the transport protocol layer. There are WTLS classes that define the levels of security for a WTLS connection:
•

WTLS class 1 involves encryption with no authentication.

•

WTLS class 2 involves encryption with server authentication.

•

WTLS class 3 involves encryption with both server and client authentication

Server authentication

Requires a server certificate stored at the server side and a root certificate stored at the client side.

Client authentication

Requires a client certificate stored at the client side and a trusted certificate stored at the server side.

A Wireless Identity Module (WIM) can contain both trusted and client certificates, private keys
and algorithms needed for WTLS handshaking, encryption/decryption and signature generation.
The WIM module can be placed on a SIM card and will then be referred to as a SWIM card.

Certificates
To use secure connections, the user needs to have certificates saved in the phone. There are two
types of certificates:
Trusted certificate

A certificate that guarantees that a WAP site is genuine. If the phone
has a stored certificate of a certain type, it means the user can trust all
WAP gateways that use the certificate. Trusted certificates can be preinstalled in the phone, pre-installed in the SWIM, or downloaded from
the trusted supplier’s WAP page.

Client certificate

A personal certificate that verifies the user’s identity. A bank that the
user has a contract with may issue this kind of certificate. Client certificates can be pre-installed in the SWIM card.

WIM Locks (PIN Codes)
There are two types of WAP security locks (PIN codes) for the WIM on SIM. The locks protect
the subscription from unauthorized use when browsing. The locks should typically be supplied
from the supplier of the SWIM.
Access lock

An access lock protects the data in the WIM. The user is asked to enter
the PIN code the first time the SWIM card is accessed when establishing a connection.

Signature lock

A signature lock is used for confirming transactions - like a digital signature.

In the T39, the user can check which transactions have been made with the phone when browsing. Each time the user confirms a transaction with a signature lock code, a contract is saved in
the phone. The contract contains details about the transaction.

Over-The-Air Provisioning Of WAP Settings
To simplify configuring WAP settings in a number of phones, all settings can be sent as an SMS
message to each phone. This makes it easy for an operator, a service provider or a company to
distribute settings for internet/Intranet, and WAP, without having to configure each phone manually. This also makes it easy to upgrade the services provided to the users, without the need for
users to perform any manual configuration.
•

The OTA configuration message is distributed via SMS point-to-point

•

The setup information is a binary encoded XML message, according to WBXML. To
receive information about OTA specifications, please contact your local Ericsson representative for consumer products. A configurator that utilizes OTA provisioning can be tested on
the Ericsson Mobile Internet

•

The user is not alerted about new settings until the ongoing browsing session ends. Furthermore, settings are not changed during an ongoing browsing session

•

The necessary user interaction is limited to receiving and accepting/rejecting the configuration message, and selecting which WAP profile to allocate the settings to

•

Security can be handled using a keyword identifier displayed on the screen as a shared secret
between the SMS sender and the receiver. It is important that the user has a way to verify
that the configuration message is authentic

Configuration Of WAP Settings
An easy way to perform the WAP configuration of a single phone is by using the step-by-step
WAP configurator provided on the Ericsson Mobile Internet. The configurator utilizes OTA provisioning, and it is available on http://mobileinternet.ericsson.com, no login required.
Another way to perform the WAP configuration of a single phone is by using the Ericsson
Phone Settings program which is available on the CD supplied with the phone. There, you can
find all configuration settings needed for the phone to access the WAP services.
A manual configuration is made using the menu system in the phone. This is described in the
User’s Guide.

Push Services
These are useful for sending updated WAP site contents or WAP links to mobile users. Examples of services that can be implemented using push services:
•

Notifications about new e-mails, voice mails, etc. Instant messaging and chat

•

News, sport results, weather forecasts, financial information (stock quotes etc.)

•

Personal Information Manager (PIM) - delivery of contacts, meeting requests etc.

•

Fill up a smart card with e-cash

•

Interactive games, e.g. play poker with a friend

In the T39, the user can select if push messages are allowed to be received or not. There are two
different forms of Push services, Service Indication and Service Loading.

Service Indication (SI)
This is basically a text message to the user, that informs of a WAP page. It contains a link to a
URL. If the user decides to load the suggested URL, normal WAP browsing commences.
When a service indication is received in the T39, the user can decide to load it, to postpone it or

to delete it. Service indications that are received are stored in the Push Inbox, and can be viewed
and loaded at a later time.
The push inbox has a list that shows the first part of each received message, which is sorted by:
1) Action attribute, high/medium/low (highest first), and
2) Reception time for messages of each attribute level

Service Loading (SL)
This is a WAP page with the updated information, that is displayed if the user accepts it. If it is
not accepted, it is loaded and stored in the cache for later use. The user can start the browser and
load the page from the cache manually.

POWERFUL MESSAGING
The T39 is capable of sending and receiving SMS messages, linked messages and it supports
Enhanced Messaging Services (EMS). Please note that EMS is only valid for T39m versions.
•

With the Short Message Service, a user can send text messages containing up to 160 characters to and from GSM mobile stations (up to 70 characters using Chinese text)

•

Status report is supported, which means that the user can see if a sent message has been
delivered or not (network-dependent service).

•

With the linked SMS, the user can link several SMS messages together to create a longer
message (network-dependent service)

•

With EMS, the T39 lets the user insert sounds, pictures and melodies, or ring tones in outgoing messages. Also, the phone will display pictures and play melodies, sounds and animations included in incoming messages (network-dependent service, and only valid for T39m
versions)

The T39 also lets you save often-used text messages as templates. You can save up to ten templates consisting of up to twenty-five characters each in the phone's memory. The T39 also features an SMS counter allowing you to keep track of SMS messages that you have sent.

Enhanced Messaging Service (EMS)
Enhanced Messaging Service (EMS) is a powerful enhancement of the SMS standard specified
by the 3rd Generation Partnership Project (3GPP). It is supported by the major network operators and mobile phone manufacturers. With it, mobile phone users can add life to SMS text messaging in the form of pictures, melodies, sounds, animations and formatted text. This gives the
users new ways to express feelings, moods and personality in SMS messages.

Add life to messages to and from the T39 by inserting melodies.

Users can express feelings and personality by inserting pictures in messages.
As well as messaging, users will enjoy collecting and swapping pictures and ring signals and
other melodies, downloading them from the internet or editing them directly on the phone. See
related documents listed under “Documents” on page 25. EMS is a network-dependent service.
One message may contain several EMS objects, such as a picture, an animation and a sound.
The message is limited by size. If concatenation is used, up to six segments of 128 bytes each
can be combined in one message.
Most phones without support for the EMS standard will simply ignore the EMS information
when the message is received, and will just display the text in the message. This prevents the
phone from displaying unreadable contents to the user.

Pictures And Animations
In the T39, there are 76 permanently stored pictures that express different moods and situations.
The pictures are grouped by eight different themes to make them easy to find. In addition, the
T39 has another 30 empty positions where the user can save pictures that have been received in
incoming messages, or have been created by the user on the phone, see “Picture Editor” on
page 19.

Examples of pictures that can be pre-installed in the T39
Animations makes it possible to further enhance the experience of the message. The T39
includes pre-defined animations for inserting into outgoing messages. In addition, the user can
receive user defined animations in incoming messages.

Sounds And Melodies
The user can include pre-defined sounds in messages, such as “Chimes high” and “Notify”, and
melodies, such as ring signals. Melodies received in incoming messages and composed by the
user on the phone’s keypad can be stored in My Melodies. These are easily inserted in outgoing
messages, see the User’s Guide. The built-in tool for editing and creating melodies on the
phone’s keypad is the Melody Composer, see “Melody Composer” on page 15.

Picture Editor
The user can edit pictures and symbols directly on the phone, to create new, personal pictures
for inclusion in EMS messages. The Picture Editor allows the user to view the picture in the display and to edit it with the pen tool.

The available tools include:
•

Set line thickness

•

Zoom in, zoom out

•

Change picture width and height

•

Select black or white pen

The T39 has a set of pre-defined pictures for use with EMS, which also can be edited. New pictures can be received with EMS messages and saved in the phone. See the User’s Guide for a
description of this function.

MOBILE INTERNET AND E-MAIL
The Mobile Internet offers much more than mobile access to the internet - it opens up a whole
new range of situation-based services. Services that give us anytime, anywhere access to personalized communications, information and entertainment. The T39 is built to facilitate the use
of and access to services on the internet. The T39 also enables new technologies such as mobile
positioning to create new commercial and productivity solutions.

Data Connections
In order to browse via WAP or use the e-mail program or an internet connection, the user must
have a connection for data communication configured in the phone. Such a connection is called
a Data connection. A Data connection contains specific settings and parameters for the connection, for example, the address to the appropriate server. Several Data connections can be saved
in the T39, with different settings. To make it easier for the user, the Data connections can be
provided by the operator in a message over the air, OTA provisioning.
Advantages of Data connections include:
•

Once the data connections are defined and named, the user does not have to enter the settings for the connection again

•

Data connections can be re-used at any time

•

When working with WAP, e-mail or the internet, the user simply selects which Data connection they want to use for the activity

•

Data connections are used for both GSM Data and GPRS connection settings

•

Data connections contain choice of bearer type for WAP and corresponding bearer specific
parameters

•

Data connections contain all settings for the internet access point, whether a modem pool
phone number or an IP address, and the user ID and password

Built-in E-mail Client
The T39 has a built-in e-mail client for sending and receiving e-mail messages. This means that
users can connect to the e-mail account normally used on the corporate network, or another email service as preferred. The same settings as those on the office PC can be used in the e-mail
client on the user’s T39. The e-mail client has several useful features:
•

A true POP3/SMTP e-mail client, it supports the majority of e-mail and web-mail servers

•

Copy of outgoing mail can be sent to the corporate e-mail server for future reference

•

The user can attach a photo from a digital camera

•

Automatic e-mail check at regular intervals selected by the user

•

More than one e-mail account in the phone, for example, one for your business e-mail and
one for your private e-mail

•

Predictive text input (T9 Text Input) facilitates typing text in e-mail body, address and subject

Mobile Positioning
The geographic location of mobile subscribers can be used to provide them with related information and a variety of services. Ericsson’s Mobile Positioning System (MPS) gives operators a
fast and cost-effective way to establish and roll out location-based services.
For users of the T39, the integration of mobile positioning with WAP services means that a
complete range of service and information tools are available.
More information regarding possibilities with and technologies for mobile positioning is available at http://www.ericsson.com/mobilepositioning and on the Ericsson Developers’ Zone, at
http://www.ericsson.com/mobilityworld.

MODEM AND AT COMMANDS
The T39 contains a complete GSM modem. This provides data and e-mail communication, as
well as internet/Intranet access, for a connected PC, PDA or handheld device. Once the PC/
PDA is connected to the phone using Bluetooth wireless technology, infrared or a cable, and the
appropriate software is installed, the modem in the phone works in a similar way to a PC Card
modem, or an external modem.
In the T39, AT commands are used both for:
•

controlling the data communication between the PC and the remote service

•

configuring and requesting settings and behaviours in the phone, from a connected PC or
PDA

GSM Data Communication
The built-in data capability turns the phone into a modem when connected to a PC/PDA. The
T39 offers the user data connection anytime, anywhere, unmatched by fixed telephone networks. Each GSM channel is divided into eight repeating time slots.
A normal GSM call only uses one of eight repeating time slots in the GSM channel, giving a
data speed of 9,600 bps. The T39 supports a more efficient coding scheme, giving data speeds
of up to 14,400 bps (providing the network supports this).

High Speed Data Gives A Faster Speed
High Speed Circuit Switched Data (HSCSD) gives the possibility to use two time slots for
receiving data. In combination with a more efficient coding scheme, this can increase the
receiving data speed up to 28,800 bps (network-dependent). Additionally, by using Data Compression (V.42bis) the experienced data rate can be increased up to four times.

GPRS Enables Constant Connection And High Speed
With GPRS, the connection is maintained “constantly”, and data is transmitted in packets. Pricing of GPRS can be dependent on the actual use of bandwidth, which means very low cost when
no data is sent or received, while the phone remains connected. When transmitting large
amounts of data, bandwidth can be increased automatically to allow faster transmission speed,
up to 39,600 bps download speed.

AT Commands Support
This section outlines the AT commands supported by the T39. The information here can be of
use for advanced users, to indicate the possibilities they have to:
•

develop new communications software

•

add the T39 to an application’s list of compatible modems

•

adjust the settings of their mobile telephone and modem

The modem in the T39 supports the V.25ter command set, which is the standard communication
set used by modems.
The T39 is compatible with industry de facto extensions, ETSI 07.05, 07.07 and 07.10.

Overview Of AT Command Functions
You use AT commands to configure your mobile telephone, to request information about the
current configuration or operational status of your mobile phone, and to test availability and
request the range of valid parameters, when applicable, for an AT command.
The built-in modem can be set in any one of three modes of operation. These are:
Off-line Command
Mode
On-line Data Mode
On-line Command
Mode

The built-in modem is placed in off-line command mode when first
powered up and is ready for entry of AT commands.
Allows “normal” operation of the built-in modem, exchanging data or
facsimile with the remote modem.
You can switch to on-line command mode when you want to send AT
commands to the built-in modem while still remaining connected to
the remote modem.

The AT commands in the T39 are grouped as follows:
•

Control and Identification

SYNCHRONIZE CALENDAR AND PHONE BOOK
In everyday life, access to an updated calendar and details of friends and business colleagues is
greatly appreciated. To be truly mobile, users must be able to carry their important information
with them. Equipping mobile phones with Personal Information Manager (PIM) programs like
calendars, to-do lists and address books gives users access to their most important data anywhere and anytime. The information is kept updated by synchronizing with the information at
the office or at home. The growing use of groupware SW such as Microsoft Outlook and Lotus
Notes means that more and more meetings are booked electronically in daily business life.

Infrared
Bluetooth

Internet/Intranet

WAP

The user can save up to 200 appointments and tasks in the calendar, depending on the size of
each item. These can be kept up to date with the user’s other calendars and agenda programs on
a PC or on a PDA or on the internet. The hierarchical phone book is also easily updated in the
same way.

Synchronize With Local Calendar And Phone Book
Open standard

Communication with almost any groupware or office program, since
the synch method complies to the open standard IrMC 1.1, as specified
by the Infrared Data Association, reference http://www.irda.org. IrMC
1.1 brings together the following standards:
vCard 2.1 for address book information
vCalendar 1.0 for appointment and to-do information
ObEx (Object Exchange) protocol version 1.0, for data exchange

Bluetooth wireless technology, infrared or cable
The T39 synchronizes using the same protocol, regardless of connection type. It connects via Bluetooth wireless technology, infrared or
cable. The cable is connected either directly to the phone or to the
desktop charger.
Automatic synch

When infrared or Bluetooth wireless technology is switched on in the
phone, the synch process starts automatically, as soon as the phone is
within range of a compatible port on a PC or handheld device (a suitable synchronization program must be running on the device).

Intelligent process

A synchronization engine performs the task of synchronizing. For local
synchronization the synchronization engine is an application running
on the desktop computer. The synchronization engine compares,
updates and resolves conflicts to make the information in the phone the
same as in the computer.

Synchronize Over WAP Using SyncML
The synchronization in the T39 with a remote internet calendar takes place over WAP according
to SyncML. The SyncML initiative is an open industry initiative, that has been formed to
develop and promote a common protocol for synchronizing data among workstations, network
application servers, and mobile information appliances, such as mobile phones, handheld computers, PDAs and other mobile devices. Ericsson is an sponsoring member to the SyncML initiative. More information is available on the official SyncML web site, see “Links” on page 44.
A synchronization engine is located on a server or on the corporate network to perform the task
of synchronization. The Ericsson AirCalendar is an example of a server-based product that helps
the users in an organization to update their phone books and meeting agendas over the internet.

Hierarchical Phone Book With Contacts
The T39 features a hierarchical phone book. For every contact, you can store name, home, work
and mobile numbers, e-mail address and other information. The hiearchical phone book in the
T39 is compatible with most groupware and agenda programs, such as Microsoft Outlook. This
enables a smooth synchronization of contact names and numbers in the phone and contacts on
the user’s PC.

Synchronization Software And The T39
A very efficient enterprise solution is to use the T39 together with PCs equipped with XTNDConnect PC For Ericsson. It provides a fast, flexible and easy to use synchronization solution.
The integration between XTNDConnect PC For Ericsson and Microsoft Outlook provides an
embedded menu for one-key synchronization.
•

A mobile worker typically uses SMS and Phone Book Manager

•

An office worker typically uses XTNDConnect PC For Ericsson and Phone Settings

To enhance the functionality and compatibility further, the synchronization software can easily
be upgraded.
The number of units that can talk to each other is unlimited. One phone can be partner with several PCs. This ensures that information from both the work PC and the home PC can be synchronized with the phone. For users that have both a desktop PC and a laptop or a PDA, it is an
efficient way to synchronize data with the phone. This way, data can also be transferred between
PCs to keep them in synch.

One phone can synchronize with an unlimited number of Pcs/PDAs.

If the synchronization software is upgraded to XTNDConnect PC, one PC can be partnered with
several different phones. This is vital if, for example, each member in a work group has his/her
own the T39, and needs to synchronize with one PC. It makes it easy, for example, to download
a common company phone directory to the phone book in each company mobile phone. With
the full version of the synchronization software, other phone types and handheld devices, such
as PDAs and Windows CE computers, can also be synchronized.

With the full version XTNDConnect PC, any number of phones can be synchronized with the
same PC.

like meeting planner, tasks, contacts and shared views. The synchronization engine can reside
on the user’s own desktop PC or on an enterprise server. AirCalendar gives supplementary features and benefits with its synchronized calendar.
The T39 can be synchronized with the web-based calendar over WAP. No browsing is required.
•

Entering a URL, a user name and a password in the phone is all that is needed to initiate the
synchronization

•

The web-based calendar is maintained from any browser connected to the internet

•

Members of a work group can let other members and associates view and enter appointments in the web-based calendar. The synchronization engine always compares appointments to try to resolve any conflicts

•

The user can request to be automatically notified of any changes to the calendar, via e-mail
or SMS

For more information about Ericsson AirCalendar, refer to http://www.ericsson.com/aircalendar.

INFRARED TRANSCEIVER
Infrared communication creates a data link between two communications devices through an
infrared beam of light. On the T39, this link is used as a wireless connection with desktop computers, PDAs, Ericsson handheld computers, laptop PCs, digital cameras, other phones (for
example, the T39), and other hardware supporting the standard. The Infrared Data Association
(IrDA) has set the hardware and software standards that form the infrared communication links.
The T39 complies with the specification IrMC 1.1, which defines how mobile telephony and
communication devices can exchange information. In the T39, a subset of the specification
IrMC 1.1 is also used when communicating via a cable.
Key benefits using the T39 with its built-in infrared transceiver:
•

True wireless communication

•

Low power consumption

•

Secure data transmission

•

Support for Medium Speed Infrared (MIR) to provide fast communication

•

Support for instant detection of infrared port from a PC running Windows 2000

•

Send and receive e-mail and data on the connected PC/PDA

•

Connect to the internet or Intranet/LAN from the connected PC/PDA

•

Support for connecting via GPRS networks (network-dependent service) also from a PC
running Windows 9x/ Windows Me / Windows 2000

•

Manage the phone book and the phone settings from a PC

•

Attach a photo from a digital camera via an infrared connection, using IrTranP (Infrared
Transfer Picture)

•

Exchange business cards and calendar events with vCard/vCalendar compatible devices

•

Exchange ring signals between compatible devices

•

Alternatively, if no infrared eye is available, an optional RS-232 cable connection is supported

Connection Via Infrared
IrDA is a point-to-point communication link between two infrared ports. The infrared beam has
to be directed towards the target infrared port and as long as the two infrared ports are within
sight and range, the devices exchange data. For optimal performance, place the T39 within a
metre and at a 30 degree angle from the infrared port on the PC/PDA, or other phone. One
advantage of this narrow infrared gap is that the risk of transmitting data to other devices nearby
is minimized. The infrared link is a serial connection, which means that the data bits are sent
one after another in a long stream. The IrDA–SIR Data Link Standard is a protocol that makes
transmission of data faultless. The IrDA–SIR standard provides a high level of noise immunity,
which means that it is not sensitive to fluorescent light, sunlight and electromagnetic fields. This
makes it suitable for a modern office environment.

Connection Via Cable
The infrared connection is not always the best solution when connecting to a PC/PDA. Indeed,
it is not always even possible. The optional DRS-10 cable provides the same connectivity
between the phone and another unit.

FUNCTIONS AND FEATURES
In-phone Functions And Features
Downloadable Background Pictures
The T39 makes it possible to use a favourite picture as a background in the display. The phone
has a list of five pre-installed pictures, and one position for a custom picture that the user can
download from another phone or from a PC or using WAP. In addition, one picture can be preinstalled by the operator, such as an operator logo.
When the user chooses to display a background picture, the menus, icons and operator name
shown in the display are re-grouped to leave room in the center of the display for the background picture.
Picture format is GIF with four grey scales (no animation). The displayed picture size is 73 pixels wide and 26 pixels high, measured from the top left corner of the picture. If a picture is too
wide (or too high) it will be truncated at the right (or bottom) edge.

73 pixels
26 pixels

4 grey scales

The user can design a suitable background picture from a photo or an illustration, using editing
equipment on a PC. The maximum picture file size for transferring to the phone is 600 bytes. If
a picture file size is too large, it will not be recognised by the phone.
•

The picture is sent to the phone from a PC or another phone using Bluetooth wireless technology or infrared. The user selects which transfer method to use for receiving. When the
picture is received, the user accepts and saves it as a background picture.

•

Using WAP, the users will be able to find downloadable pictures on WAP sites, for saving as
custom picture in the phone.

•

Operators can prepare logos or custom pictures for pre-installation in the T39. The phone
can be set to display the operator logo as default background picture by customizing.

Profiles
The profile feature: a group of settings preset to suit a certain environment. The profiles are also
related to intelligent accessories such as a desktop charger, a portable or vehicle handsfree; useful for company integration with call forwarding etc. Some phone accessories select a profile
automatically. For example, when you place your phone in a car handsfree unit, the “In car”
profile is chosen.
The easiest way to set up the profiles in one or several phones, is by using the Ericsson Phone
Settings program.

Predictive Text Input (T9 Text Input)
The predictive text input (T9 Text Input), makes it possible for the phone to quickly recognize
the most commonly used word beginning with a certain letter. This is convenient especially
when writing long messages, such as text messages and e-mail, if the input language you select
supports this. For example, if you press 2, 6, 3, the word “and” appears, since this is the most
commonly used word with this combination of letters.

Voice Control
The T39 supports enhanced voice control, which makes it possible to interact with the phone
using spoken commands. This is useful for handsfree use of the telephone. The functions
include:
•

Voice dial - call someone by saying the name and number type, e.g “John, home”

•

Answer and reject calls with your voice when using a handsfree kit

•

Change profile with your voice

•

Record or listen to voice memos with voice commands

•

Caller name can be presented with the recorded voice command

•

Activate the voice control with a “magic word”

The Magic Word
The user can record a magic word and use it as a voice command to allow totally handsfree
access to voice control. Instead of pressing and holding YES, just say the magic word and then
one of the recorded voice commands. Activating the magic word consumes more power than in
normal standby mode. The magic word is especially suitable when driving a car with a car
handsfree kit installed, because external power is used instead of the battery power of the phone.
The user can also can also use the magic word when the phone is connected to a portable handsfree.

Hierarchical Phone Book
In a company or an organization, you may need to deploy several phones with a common set of
phone book entries. This is done in one of the following ways:
•

Use the Ericsson Phone Book and SMS Manager on your PC to prepare the common phone
book entries. Then send the phone book entries from the PC to each and every phone. See
the User’s Guide.

or
•

Prepare the phone book on one SIM card in one phone. Copy the contents from this SIM
card to the phone’s memory, then put each one of all the other SIM cards into the phone and
copy the contents of the phone’s memory to them. See the User’s Guide.

Voice Memo
Voice memo is accessed through the regular menu system. You can record either your own voice
or the voice of the person with whom you are speaking. You can also record short memos to
yourself. Total record time 92 seconds for normal quality mode, and 36 seconds for high quality
mode.
Note that you may not be allowed to record the voices of other parties in conversation. Please
check the appropriate regulations before using this function.

Calendar Entry Exchange
Calendar entries can be exchanged with other programs, according to the vCalendar specification. Using vCalendar, events, appointments, “ToDo” items and meeting information can be
“beamed” to and from any IrDA equipped device with support for vCalendar, including PDAs,
PIMs, laptops and phones.

Ring Signal Exchange
The T39 supports exchange of ring signals to and from other compatible phones.

Business Card Exchange
Business cards can be exchanged with other devices, according to the vCard specification.
vCard information can include name, phone number, e-mail address, and so on. Laptops, PDAs,
phones or other devices equipped with IrDA or Bluetooth wireless technology, and that supports
vCard, can “beam” business cards.

Fixed Dialling And Restricted Calls
For a company or an organization, it can be useful to restrict phone calls. Fixed Dialling allows
you to preset a number of digits, for example area codes. This restricts the user to making calls
only to numbers which use the preset digits as leading digits. Fixed Dialling makes use of the
PIN2, and it requires fixed dial fields on the SIM Card. Check with your Operator about this
feature.
Restricted calls allows you to block outgoing or incoming calls in certain situations, for example international calls.

WAP 1.2.1

SIM APPLICATION TOOLKIT
The SIM Application Toolkit (SIM AT) is a smartcard-centric method of deploying programs
that apply only to GSM and to SMS and USSD transports. Programs must be distributed on
smartcards. WAP is an internet-centric method of deploying programs that is independent of
network technology. Programs and content are kept centrally on web servers and downloaded as
required. While there is some overlap, WAP is a particularly good choice when deploying programs that also have an HTML version for desktop use. Work is currently underway on building
interfaces between the two technologies.
For an operator, a company or service provider, SIM AT offers a powerful way to deploy programs and services to users, without the need for new or upgraded equipment. All necessary
setup and programming is distributed to the users over the air, directly to their phones. In the
T39, a separate menu is available for functions residing on the SIM card. These can include submenus for controlling functions, and also functions which allow the phone to initiate calls, send
data, and display information for the user.
