White Paper, April 2002

MMS (Multimedia
Messaging
Service)
One of the key features in the T68i is the
Multimedia Messaging Service (MMS), expected
to become the preferred messaging method of
mobile terminal users, since there are virtually no
limits to the content of an MMS transmission. An
MMS message from the T68i can contain text,
graphics, animations, images, audio clips and
ring melodies. For more detailed information, see
“Multimedia message service” on page 54. For
third-part developers’ information, please visit
www.ericsson.com/mobilityworld/ and look for
the MMS Developers’ guidelines.
Defined and specified by 3GPP as a standard for
third generation implementation, MMS completes
the potential of messaging. Sending digital
postcards and PowerPoint-style presentations is
expected to be among the most popular user
applications of MMS. Eagerly awaited by young
users in particular, MMS is projected to fuel the
growth of related market segments by as much
as forty percent.
Using the Wireless Application Protocol (WAP) as
bearer technology and powered by the high-
speed transmission technologies EDGE, GPRS
and UMTS (W-CDMA), Multimedia Messaging
allows users to send and receive messages that
look like PowerPoint-style presentations. The
messages may include any combination of text,
graphics, photographic images, speech and
music clips . MMS will serve as the default mode
of messaging on all terminals, making total
content exchange second nature. From utility to
sheer fun, it offers benefits at every level and to
every kind of user.
MMS objects
Although MMS is a direct descendant of SMS,
the difference in content is dramatic. The size of
an average SMS message is about 140 bytes,

word to describe MMS content is rich. Complete
with words, sounds and images, MMS content is
endowed with the user’s ideas, feelings and
personality. An MMS message can contain one or
more of the following:
Text
As with SMS and EMS, an MMS message can
consist of normal text. The length of the text is
unlimited, and it is possible to format the text.
The main difference between an EMS and MMS
message is that in an MMS message, text can be
accompanied not only by simple pixel images or
melodies but by photographic images, graphics,
audio clips and in the future, video sequences.
Template s
The T68i comes with a number of MMS pre-
defined templates, for example templates for
birthday cards, meeting requests etc.
Audio
MMS provides the ability to send and receive full
sound (iMelody and AMR) messages. Not only
can users share a favourite song ot ring signal
with a friend, they can also use the mobile phone
to record sound and send it along with a
message. Because sound includes speech as
well as music, this extra dimension of an MMS
message makes for enhanced immediacy of
expression and communication. Rather than
