MMS - Multimedia Messaging Service

-

Multimedia Messaging Services (MMS) - Sometimes called Multimedia Messaging System - is a communications technology developed by 3GPP (Third Generation Partnership Project) that allows users to exchange multimedia communications between capable mobile phones and other devices. An extension to the Short Message Service (SMS) protocol, MMS defines a way to send and receive, almost instantaneously, wireless messages that include images, audio, and video clips in addition to text. When the technology has been fully developed, it will support the addition to text. When the technology has been fully developed, it will support the transmission of streaming video. A common current application of MMS messaging is picture messaging (the use of camera phones to take photos for immediate delivery to a mobile recipient). Other possibilities include animations and graphic presentations of stock quotes, sports news, and weather reports.


According to Mobile Streams, MMS will be developed in two separate phases. Based on General Packet Radio Services (GPRS), the currently available MMS is similar to a brief PowerPoint presentation. The second phase of MMS will require a 3G network to enable streaming video. An intermediate technology, Enhanced Messaging Services (EMS) has more capabilities than SMS, but fewer than MMS. Unlike MMS, EMS doesn't require upgrades to network infrastructures. Unlike SMS and EMS, the size of an MMS message is unlimited, although service providers are likely to impose their own size restrictions.

What is MMS ?             (5 marks ques.)

Multimedia Messaging Services (MMS) is a store and forward messaging service that allows mobile subscribers to exchange multimedia messages with other mobile subscribers. It is an important emerging service, which allows the sending of multiple media in a single message, and the ability to send a message to multiple recipients. Each Multimedia Message contains a number of pages (think of a PowerPoint slide show as an analogy). On each page, there can be one image and one set of text. An audio file can also be attached. The time that each "page" is displayed can be specified, so the user experience is somewhat like a slide show.

An example of how to transfer a Multimedia Message, using an MMS compatible phone-
1. Take a photo.
2. Use your phone to personalize the message by adding text, sound clip or your own voice.
3. Send the MMS message on a compatible phone.

The message will appear with a new message alert. The picture message will open on the screen, the text will appear below the image and the sound will begin to play automatically, if the message is sent to a non-compatible MMS phone the user will receive a SMS message along the lines of: "You have been sent a picture message!"
