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 messaging, for exam
-
ple 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.
