Benefits
Essentially enabling the mobile terminal to serve as 
image processor and conveyor, Multimedia Mes-
saging accommodates the exchange of important 
visual information as readily as it facilitates fun. 
Business and leisure usage of MMS will be dynam-
ically merged, resulting in enhanced personal effi-
ciency 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 interop-
erability is assured. 
The MMS server, through which MMS messages 
are sent, supports flexible addressing (to both nor-
mal 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 mes-
sages, rather than a mailbox-type model. MMS is a 
person-to-person communications solution, mean-
ing 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 tech-
nologies EDGE and GPRS and support a variety of 
image, video and audio formats to facilitate a com-
plete 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 supporting flexible 
addressing. The centre’s MMS Proxy-Relay inter-
acts with the application being run on the MMS-
enabled terminal to provide various messaging 
services. WAP is used as bearer of an MMS mes-
sage between the MMS-C and the MMS client 
(application). The WAP Gateway is used for delivery 
and retrieval of messages.
