The Conformance and Interoperability Test Framework for Home Subscriber Server Implementation

Features

• Support of 3GPP release 6 and 3GPP release 7
• 88 tests for
  • Location management procedures
  • User data handling procedures
  • Authentication procedures
  • Subscription and notification procedures
• Tests for valid and invalid DIAMETER protocol behavior and syntax variations in DIAMETER messages
• Exhaustive set of context parameters for flexible adaptation of TTCN-3 tests to the HSS implementation under test
• Fully automated test execution
