This is an overview of the concept of Telecom Performance Management System for Tier-1 and Tier-2 operators.
The main features of this concept are:
- full coverage of all TMN model layers
- the ability for extension to full FCAPS model
- integration with any third-party systems
- distributed and fault-tolerant database model optimized for very large data volumes

  • 2. Operators need PM system to:
    Predict, analyze and investigate network and service performance degradations
    Generate and present network and service performance reports to company management
    Forecast network and service performance in case of events (Exhibitions/Trade Shows, New Year, Olympic games) or new product launches
    Control compliance with SLA on outsourced equipment
