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.
