Your USSD provider should give instructions how to use the api. Smpp is merely used to convey the messages to/from the user by using the standard pdus (submit_sm and deliver_sm). Probably some TLVs will be used (imsi is a good example) and other notable difference is that ussd is session based, so you might have session_id as a parameter somewhere. Anyway, you need to study your provider’s api and ussd as a service a little bit.
