This TS contains the core functions for a non realtime Multimedia Messaging Service, MMS, which are
sufficient to provide a basic service.
It describes how the service requirements are realised with the selected technologies. As far as possible
existing protocols (e.g. WAP, SMTP, ESMTP as transfer protocols; lower layers to provide push, pull, notification) and
existing message formats (e.g. SMIL, MIME) shall be used for the realisation of the Multimedia Messaging Service.
