Hi list, I managed to add interaction to the USSD implemented in the OpenBSC.
I attached a patch with the changes realized.The most important changes made
are in the ussd.{c, h} files. I implemented the gsm0480_send_ussd_facility.
Basically, I copied the gsm0480_send_response, change the
GSM0480_OPERATION_CODE field value to GSM0480_OP_CODE_USS_REQUEST, removed the
2 bytes before this field and replaced the GSM0480_MTYPE_RELEASE_COMPLETE byte
by GSM0480_MTYPE_FACILITY.
Now, I don't know how to proceed. More precisely, I don't know what function is
called in the OpenBSC when the user send the response in the mobile phone.
Do you guys know the entry point function in this case ?
Best Regards
patch_ussd.patch
