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
