Dear sir,
Thank you very much!
According to what you said, kannel doesn't
implement the UDH header now. Do you have a plan?
and would you pls tell me which optional parameters
in submit_sm are UDH header? and which protocol depicts the UDH?
Best Regards, Guanghua Hou UTStarCom

Right. UDH
indicator must be set to tell the handset that there is a user data header
present. the user data header is prepended to the payload.
This value doesn't
indicate this short message is WAP push

It does not. SMSC's are
there to transport SMS, not wap data. an SMSC is not a wap gateway of any
sort. So it doesn't have to know anything about wap push but still can
transport the WAP push PDU. Check out the GSM specs for SMS-PDU's in the
GSM networks. There is nothing in there about WAP. WAP was invented far after
SMS so SMSC's don't have to know if this is a wap push. Handsets do. Thats why
there is a UDH header indicating WAP ports.
