Franco,

I think you forgot to the the UDH bit in the first octet of the PDU (you have 0×01 for SUBMIT PDU, change this to 0×41 for SUBMIT PDU + UDH). You don’t need the concatenation IE.

Franco,

No, you can’t do this with WAP push. There is a way of doing it without setting the DCS though. There is an UDH IE that has the same effect as setting the message waiting flags in the DCS. It has an additional feature: it lets you set the message count (how many message are waiting). I haven’t seen any device showing the message count though.

Here is a brief description of the IE
- IEI = 0×01 (this identifies this IE as a “special SMS message indication”)
- IE length = 0×02 (this IE always has 2 octets of data)
- 1 Octet = message type
- 1 Octet – message count

The message type is
- 0×00 for voice message
- 0×01 for fax message
- 0×02 for email message
- 0×03 for other message

Set the first bit of the message type (0×80) to let the device store the message, discard is the default

Jeroen:
Tried DCS(0xDA) Trun on e-mail (Store).
Works perfect.
A sms is stored at my inbox OK.
Is there a way to make such sms as a wap push sms?
What I actually do is to send a text link and from there the broweser, via get, takes you to the URL.
Using a Carriage Return, I send two links; one goes to the ‘mail server wap main page’ and the second one automatically ‘downloads via sms the headers of the mail’ received.
If such message could be turned into a wap push, I think
it would be much better!:
