Interactions and interdependencies in the converged network create a complex environment. Performance issues after deployment can result in loss of profits and customers.

An IMS implementation offers the opportunity to monetize new services, but it also presents hundreds of failure points. Interactions and interdependencies in the converged network create a complex environment. Performance issues after deployment can result in loss of profits and customers. Carriers should conduct IMS testing before deployment to confirm that they can deliver the performance and quality of experience subscribers expect.

What to Test

IMS testing should validate

  • High call volume (hundreds of thousands) with high MOS quality
  • Five-nines service availability with high QoE
  • Performance under realistic network conditions, such as jitter, latency and loss
  • User authentication and service level assignment
  • CDR billing record generation for all services and customers
  • Failover schemes
  • Encryption while maintaining throughput
  • Security policies to prevent outages due to malicious attacks
  • Interworking with new and legacy networks

Spirent Solutions

Spirent’s IMS testing solutions produce the complexity and scale needed to validate IMS performance under real-world conditions:

  • Abacus tests scalability, performance, interoperability and voice quality for voice over IP prior to and during deployment
  • Landslide simulates real world traffic models to evaluate wireless core packet data networks
  • Support Services ensure that system technology is always current and operating at maximum performance
