NexusVERIFIER – Mobile Voice Services

Proactive Service Testing

Customers increasingly expect better reliability and performance of Mobile Voice services as they expand their applications to more sophisticated mobile content services.

In order to secure existing customers, service providers must verify the availability, reliability and quality of their Mobile Voice service offerings, which means that speech quality and various calling features must be continuously tested to ensure they are stable.

NexusVERIFIER is a continuous testing solution that verifies Mobile Voice quality and services are performing at the level your customers expect. By proactively testing your network at multiple tests points, operations personnel can ensure issues are quickly identified and solved – all from a central location.

  • Continuous active testing of your Mobile Voice services; quickly identify service degradations
  • Verify speech quality and/or voice announcements
  • Full Mobile Voice service assurance at lowest total cost of ownership
  • Fully scalable and automated testing
  • Centralized network-wide testing; no on-site hardware installations necessary
  • Guarantee a minimum voice service quality; improve Mobile Voice service usage rates
  • Focus on proactively solving issues rather than reactively locating them
  • Reduced calls to your customer care center

NexusVERIFIER Test Suite

NexusVERIFIER provides a comprehensive set of tests for service quality verification, including speech quality analysis. Test campaigns for fundamental call scenarios are pre-packaged and include inter-working calls, location changes and handovers. Testing scenarios are also available for supplementary services such as call forwarding, call barring and multi-party calls. With NexusVERIFIER’s Central Payload Analyzer and Speech Recognition functionality, operations personnel can actively test menu trees and speech recognition patterns for voice mail systems.

NexusVERIFIER employs a unique approach to mobile user testing by connecting the Test Module and SIM Server at a central point in the network. Mobile Voice services testing can then be simulated across the entire network without consuming any valuable air time. Thus NexusVERIFIER has a significantly lower total cost of ownership, while providing essential network-wide testing capabilities for Mobile Voice service assurance.

In addition, the solution can be extended: Verify out-bound roaming services with the International Roaming Monitoring (IRM) Extension; use the Billing Verification Extension to capture and analyze CDRs to verify accuracy of billing records.
