Applications
• Provides fault insertion, and erroneous call flows testing capability
• Performance testing, Load testing, Functional testing, Regression testing and Conformance testing of
network elements
• Ready scripts makes testing procedure simpler, less time consuming and hence time to market products
• Simulate up to 500 Smartphones (UEs) powering up and down
• Authenticate and confirm security procedures
• QoS requests for greater or lesser bandwidth
• Temporary addressing management for mobility and security
