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.

Hi can one help me on this.

 

I had one query regarding MMSE protocol.

 

MMSE specs defined by OMA say the following:

 

7.4 Header Field Names and Assigned Numbers

Bcc                                            0x01

Cc                                             0x02

X-Mms-Content-Location                0x03

Content-Type                               0x04

Date                                          0x05

X-Mms-Delivery-Report                 0x06

X-Mms-Delivery-Time                   0x07

X-Mms-Expiry                             0x08

From                                         0x09

 

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

 

Bcc                                            0x81

Cc                                              0x82

X-Mms-Content-Location                 0x83

Content-Type                                0x84

Date                                            0x85

X-Mms-Delivery-Report                   0x86

X-Mms-Delivery-Time                     0x87

X-Mms-Expiry                                0x88

From                                           0x89

 

 

 

Can u pls sugest on this.What could be the values for that.it seems traces in Wireshark traces have values 80 added to every value defined in specs.

Priyadarshi.
