It is very strange for the Content-ID header to be encoded this way. Normally the short header value of 0xC0 would be used instead of using text encoding. Content-ID is a standard MIME header. In this context of this PDU, it adds no value. However, if you were using "multipart/related", the "start=" parameter for the content-type header would point to a SMIL file by referencing its "Content-ID". 0xB0 is the "X-WAP-Content-URI" header. It is strange for that to be present in an MMS body part header. 0x92 is a "Date:" header. Again, it is strange for that to be present in an MMS body part header.
You are past the header at this point (header length = 0x42) ... that is the data content for this part. Overall, this is an odd encoding. The parts you do not understand are defined in the WAP WSP specification, as WAP multipart encoding is used for the body of an MMS message. Those headers you are asking about are standard WSP header encoding. -- Des NowSMS Support | |||
