Course Outline

Overview of Mobile Subscriber Services

  • Classification of subscriber categories and profile attributes
  • Service classifications: voice, short message service (SMS), data connectivity, and supplementary offerings
  • Management of subscriber lifecycle transitions and associated signaling requirements

Functions of OSS and NetAct Systems

  • Operational Support Systems (OSS) capabilities for performance monitoring
  • NetAct system architecture: objectives and primary components
  • Transmission of telemetry data from network elements to the NetAct platform

Fundamental Concepts of Key Performance Indicators (KPIs)

  • KPI classifications: availability, accessibility, retainability, and integrity
  • Methodologies for KPI calculation and aggregation intervals
  • Establishment of thresholds, alarm triggers, and alignment with Service Level Agreements (SLAs)

NetAct KPI Framework — Voice and Signaling Networks

  • Metrics for call setup success and call drop rates
  • Signaling KPIs specific to SS7 and Sigtran protocols
  • Analysis during peak traffic periods and capacity dimensioning indicators

NetAct KPI Framework — Data Services and Throughput

  • Indicators for data session establishment and throughput performance
  • Measurements for latency, jitter, and packet loss
  • Subscriber experience metrics, including per-subscriber throughput analysis

KPI Analysis and Root-Cause Correlation

  • Examination of performance trends and identification of baseline deviations
  • Cross-layer correlation of KPIs across Radio Access Network (RAN), transport, and core infrastructure
  • Utilization of KPI data to identify congestion points, configuration errors, and hardware failures

Reporting, Dashboards, and Alarm Management

  • Development of actionable performance dashboards for operational visibility
  • Automation of report generation and delivery tailored to stakeholder needs
  • Strategies for alarm optimization and reduction of notification noise

Troubleshooting Procedures Using NetAct Data

  • Standardized troubleshooting protocols and step-by-step procedures
  • Practical applications: resolution of voice call failures and data throughput degradation incidents
  • Criteria for incident validation and formal closure

Operational Best Practices and KPI Governance

  • Definition of KPI ownership and establishment of governance frameworks
  • Integration of performance impact assessments into change management processes
  • Implementation of continuous improvement initiatives throughout the KPI lifecycle
