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. He or she doesn’t 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
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 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 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.
