Yes, initially I thought about using SMPP for USSD. But it looked really
complicated since only few external SMPP libraries have support of USSD and
most of that few are in C#/Java/etc. Moreover I didn't have any working
software for USSD over SMPP to test interoperability with.
So I decided to use GPRS SUP socket as a simple transport to send MAP-like
messages. Workflow of this SUP is very simple and basically it forwards SS
messages with little modifications.

This series of patches add support for external USSD processing via
simplified MAP-like protocol over SUP socket. As an example of a such
external application simple USSD to SIP proxy is provided (it targets
TS 124 390)
Have you considered using SMPP for USSD? At first this looks more natural
than a custom protocol like SUP.
