are<br>based on the existing SS/USSD related test cases.<br><br>The idea of TC_lu_and_mt_ussd_notification is to verify that<br>a network-initiaded USSD notification can arrive subscriber in<br>IDLE mode using Paging procedure.<br><br>The idea of TC_lu_and_mt_ussd_during_mt_call is to verify that<br>a network-initiaded USSD notification can arrive subscriber in<br>DEDICATED mode (in this case during a call) on a separate<br>transaction.<br><br>Change-Id: I073893c6e11be27e9e36f98f11c1491d0c173985<br>---<br>M msc/MSC_Tests.ttcn<br>M msc/expected-results.xml<br>2 files changed, 299
