Messaging

MMS

MMS (Multimedia Messaging Service) is expected to become the preferred messaging method of mobile phone users since there are virtually no limits to the content of an MMS transmission. An MMS message can contain text, graphics, animations, images, video, audio clips and ring melodies. For third party developers’ information, please visit www.SonyEricsson.com/ developer/ and look for the MMS developers guidelines.

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 40%.

Multimedia Messaging uses WAP (Wireless Application Protocol) as bearer technology which can also be powered by the high-speed transmission technology EDGE/GPRS. This 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.

OTA configuration

Users can easily get MMS into their phone. MMS supports OTA, meaning that the user does not have to configure the settings manually. The configuration is done by the operator.

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, while the maximum size of an MMS message is about 200 Kbytes (limited by both the memory capability of the mobile phone and less than ideal network conditions), enabling much richer MMS content. 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 (Enhanced Messaging Service), an MMS message can consist of normal text. The length of the text is unlimited. 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 video clips.

Templates

The phone 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 audio as part of messages. The phone supports iMelody, MIDI, and AMR formats. Not only can users share a favorite song or ringtone with a friend, they can also use the mobile phone to record a sound or message and send it along with a text message. As sound includes speech as well as music, this extra dimension to an MMS message allows for a spontaneous and immediate personal
