I'll try to implement some basic test coverage.

As I understand, we need to emulate the following:

  • subscribers, sending and receiving USSDs at the same time (according to 3GPP TS 04.80);
  • TTCN-3 based external USSD gateway (as soon as I finish the GSUP interface);
    • network initiated USSD-sessions;
    • subscriber initiated USSD-sessions;
    • error cases during USSD-sessions (e.g. losing connection with USSD gateway);
    • multiple USSD-sessions with a single subscriber (on both MM and transaction levels);
