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-email, 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 and HTTP is used as the 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.
Message conversion
The MMS-C is able to perform limited message
conversion - for example, from MMS to SMS - so
that processing and air time is not wasted in send-
ing messages to mobile terminals that do not have
adequate capability to receive them. It also handles
service aspects such as store and forward, guaran-
teed delivery, subscriber preferences, operator
constraints, and billing information.
The MMS-C also vouches for high quality messag-
ing, for example by format conversion. This means
that the MMS-C recognizes which formats are sup-
ported in the mobile phone, and adapts the MMS
messages to these formats.
