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.
