Reports Overview • 1. System Program System Program gives a general overview of network status. With this report the user can achieve in high level how network is performing and understand if problems are occurring. 2. Accessibility and Retainability
• Accessibility and Retainability Subset provide detailed
• analysis and root failure causes for problems when trying
• to access the network or troubleshooting of drop
• calls/services.
• The subset is divided into three reports:
• Network Access - General and S1AP
• Network Access - Service Access and RRC
• Service Retainability 3. Mobility
• Mobility subset provides handover and mobility • statistics. Decision rate, Intra eNB, Inter eNB and • Neighbour HO performance are available.
4. Interface analysis Interface Analysis subset provides statistics of X2, IP and Ethernet Interfaces. Metrics per VLAN and per QoS Class are also available in these reports. 5. Modulation and Coding Scheme Modulation and coding scheme subset provides statistics of X2, IP and Ethernet Interfaces. Metrics per VLAN and per QoS Class are also available in these reports. 6. Integrity
With Integrity subset is possible to analyze delays, congestions and Encryption / Decryption metrics. 7. Usage
With Usage subset is possible to analyze throughputs, resources utilization, power and number of active users. 8. Signal Quality With Signal Quality subset the user can understand interference levels, signal strength distribution and channel quality indicator.
