USSD messages

Post by splogic » Tue Jan 22, 2013 5:08 pm

Hello all!

Tryed to manage a simple USSD application, it works fine. app seems to be very simple, thanks to InetLab.
Now just wonder if i can send with SubmitSm one message of 180 characters len? The operator says that they can accept such long ussd messages.

Thanks for any advice,
SP

Hello splogic,

How operator recommends to send long messages? In short_message field or in message_payload?

When you create SubmitSm it should be possible to specify 180 bytes array in property
sm.UserDataPdu.ShortMessage

Maybe you need to send concatenated SubmitSm parts?

Hi,

How do i know that an incoming deliverSM is a USSD message and it properties. And how do i reply to that particular message, does it come with session IDs ?

Hi Gaska,

USSD over SMPP is usually SMSC specific solution. Do you have any description from them?

It is difficult to give general advice for USSD over SMPP. Please request description from your provider and send me by email.
It helps me to give you right direction for processing USSD messages.
