Private Cellular dashboards
All supported dashboards are described in subsequent sections.
Private Cellular Alarms dashboard:
The alarms dashboard is a view of reactive monitoring for events that might require action (active) or that can be cleared when no action is required. In this dashboard, you can get an overview of alarms by severity and location, the top events triggering the most alarms, and the types of devices triggering them. In this view, you can also see the days and times when the alarms are typically triggered so that preventive actions can be planned.
Private Cellular Performance dashboard:
The Cell Performance dashboard provides an overview of key performance metrics for cell devices, including ranks and availability ratios. It identifies poor-performing cells by location and features a daily performance heat map. Key performance indicators (KPIs) include ranking, availability, retainability, mobility, accessibility, and integrity/quality. Performance is categorized as Below Average (0–2), Average (2–3), Good (3–4), or Excellent (4–5). This KPI assesses service availability in cells for end users, focusing on:
RRC connection establishment.
Initial E-RAB setup for network access.
Data radio bearer setup via RRC connection reconfiguration.
E-RAB setup between MME and UE.
It also tracks the following:
- Abnormally released E-RABs ratio.
- Uplink/downlink retransmission ratios for RLC PDUs.
- Lost PDCP SDUs ratio. - Handover success ratios (intra-eNB and inter-eNB).
- RA preamble responses ratio to total RA preambles.
Private Cellular Executive view dashboard:
The Executive View Dashboard offers a comprehensive overview of the key devices in the Private Cell network, including Edges, Access Points, and Cells. It displays existing alarms categorized by device type and Location, along with essential indicators of connectivity, availability, and throughput for both uplink and downlink. Additionally, the dashboard highlights trends in these metrics and provides a summary of performance rankings and trends by Location.
