I'm attempting to find information on the MMS Adaptations field. Specifically I want to know the assigned number for this field on the MM1-Submit.REQ. The only reference to the Assigned Number for MM1 field encapsulation is the wap-209-mmsencapsulation-20020105-a.pdf which doesn't contain this field.

If the information I've found is correct it is because this field is new to the MMS 1.2 spec and the encapsulation spec was written before that.

My current understanding is that this is a field encoded in the MMS PDU similar to 'content-type', 'mms-version', etc and that is was introduced with the MMS 1.2 spec. I'd like to know what the octet is for this field (i.e. content-type is 0x84: 0x80 + 0x04).

If my assumptions are wrong can you please point me in the direction of some more adequate documentation on the "adaptations" field as referenced in the 3GPP 23140-6f0.doc.

Thank you

Hi,

Actually, I don't think that particular field is define in MMS Encapsulation until OMA MMS 1.3.

BC 80 for X-Mms-Adaptation-Allowed: Yes

BC 81 for X-Mms-Adaptation-Allowed: No


The 1.3 spec should be available for download in release program section of http://www.openmobilealliance.org/Technical/released_enablers.aspx. I believe it is still a candidate release, and not finalized, although it has not changed for some time.
