Hello Priyadarshi,
In theory this question doesn't really seem to have anything to do with Wireshark development, but is a question related to the a specific protocol. Nonetheless, here's the answer:
According to section
7.1 of the same specs you mention... <quote>MMS-field-name = Short-integer</quote>
According to "Basic rules" section of the WSP specs...
<quote>
Short-integer = OCTET
; Integers in range 0-127 shall be encoded as a one octet value with the most significant bit set
; to one (1xxx xxxx) and with the value in the remaining least significant bits.
</quote>
This is the cause of the addition of 0x80 to the assigned numbers in the encoded PDUs.
I think you have posted the same question at
http://discussion.forum.nokia.com/forum/showthread.php?t=117896, so I guess that's answered too!
Best regards,
Abhik.

Where as I find in some traces captured by Wireshark which
gives the values as
Bcc

X-Mms-Content-Location
0x83
Content-Type
0x84

defined in specs.
