Messaging

MMS

An MMS message can contain

text, graphics, animations, images,

audio clips and ring melodies. For third party developers’ information, please visit www.SonyEricsson.com/developer and

look for the MMS developers guidelines.

Multimedia Messaging uses WAP (Wireless Appli- cation Protocol) or http as bearer technology which also can be powered by the transmission technol- ogy GPRS. The messages may include any combi- nation of text, graphics, photographic images 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.

Over the air (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 configura- tion is done by the operator via OTA.

Note: The specification is in accordance with Erics- son Nokia OTA configuration v7.1.

MMS objects

The key 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 text, sound and pictures.

MMS technical features

The MMS standard, just like that of SMS, offers store-and-forward transmission (instant delivery) of messages, rather than a mailbox-type model. MMS is a person-to-person communications solution, meaning that the user gets the message directly into the mobile phone. He or she does not have to call the server to get the message downloaded to the mobile. Unlike SMS, the MMS standard uses WAP as its bearer protocol. MMS will take advan-

tage of the high speed data transport technology GPRS and support a variety of image and audio formats to facilitate a complete communications experience.

Architecture

The MMS Centre (MMS-C) is comprised of the MMS Server, the MMS Proxy-Relay and the MMS Store. The MMS Centre is the central element of the MMS network architecture, providing storage and operational support, enabling instant delivery of multimedia messages from terminal-to-terminal and supporting flexible addressing. The centre’s MMS Proxy-Relay interacts with the application being run on the MMS-enabled terminal to provide various messaging services. WAP or http is used as the bearer of an MMS message between the MMS-C and the MMS client (application). The WAP Gateway is used for delivery and retrieval of mes- sages. Information is read in the WAP browser.
