The T2 MMS adHoc group is currently defining mandatory media types, media compression schemes and media file formats for Release 2000. In order to signal these media streams within a message the group has decided to use the MIME concept. This concept is already widely used, e.g. attachments in Emails are encoded by MIME.

In order to structure all MIME types, the organisation IANA (www.iana.org) registers all types by the subtype name (IETF tree, Personal Tree and Vendor Tree) and by the media type name (video, audio, application, message, text, multi-part, image and model).

Therefore the T2 MMS adHoc group proposes to register a new subtype name (3GPP tree) that should cover all 3GPP-types. For example the MIME type for SMS shall be registered under 3GPP/text/SMS. In order to centralise the registration process of 3GPP types, the MMS adHoc group proposes that T2 takes the responsibility for this process. 

T2 adHoc is highly interested in a feedback from T2 on this MIME matter and would be happy to assist if questions arise.
