Benefits
Essentially enabling the mobile terminal to serve as
image processor and conveyor, Multimedia Messaging
accommodates the exchange of important visual
information as readily as it facilitates fun. Business and
leisure usage of MMS will be dynamically merged,
resulting in enhanced personal efficiency for users and
increased network activity for operators. In short, MMS
affords total usage for total communication
Because MMS uses WAP as its bearer technology and is
being standardized by 3GPP, it has wide industry support
and offers full interoperability, which is a major benefit
to service providers and end users. Ease-of-use resulting
from both the gradual steps of the messaging evolution
and the continuity of user experience gained from
interoperability is assured.
The MMS server, through which MMS messages are
sent, supports flexible addressing (to both normal phone
numbers (MSISDN) and e-mail accounts), which makes
user interface more friendly and allows greater control
for operators. The MMS server, moreover, is responsible
for the instant delivery feature of MMS.
MMS technical features
The MMS standard, just like 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 doesn’t have to call the server to get the message
downloaded to the mobile phone. Unlike SMS, the MMS
standard uses WAP as its bearer protocol. MMS will take
advantage of the high speed data transport technologies
EDGE and GPRS and support a variety of image, video
and audio formats to facilitate a complete
communication 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 terminal-to-e-mail, and support-
ing flexible addressing. The centre’s MMS Proxy-Relay
interacts with the application being run on the MMS-ena-
bled terminal to provide various messaging services.
WAP is used as bearer of an MMS message between the
MMS-C and the MMS client (application). The WAP
Gateway is used for delivery and retrieval of messages.
