thanks for your reply. I think I did not explain the question properly. Let me Explain with the help of example. UDH Header would be something like this (PDU Mode)
First Message:
05 00 03 21 02 01
where
05 = total header length
00= Element Identifier for Long Message Header
03= size of the header for Multipart message header
21= Unique Identifier
02= total number of parts
01= Part number of message
For second Message
05 00 03 21 02 02
Now If I want to edit this information and bring the packets information into continous unlimited flow
how can I do that.
thanks.
