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
sending messages to mobile terminals that do not
have adequate capability to receive them. It also
handles service aspects such as store and forward,
guaranteed delivery, subscriber preferences,
operator constraints, and billing information. The
MMS-C also vouches for high quality messaging,
for example by format conversion. This means that
the MMS-C recognizes which formats are
supported in the mobile phone, and adapts the
MMS messages to these formats.
