LTE Utilization KPIs are used to assess the network’s ability to handle traffic demands under specific internal conditions. These KPIs help evaluate the resource usage efficiency in the LTE network.
1. Downlink Resource Block Utilizing Rate.
This KPI measures the utilization rate of downlink Resource Blocks (RBs) during the busiest hour in a cell or across the entire radio network. It reflects how efficiently the downlink resources are being used to meet traffic demands.
The Downlink Resource Block Utilizing Rate KPI is defined in Table below.
2. Uplink Resource Block Utilizing Rate.
This KPI measures the utilization rate of uplink Resource Blocks (RBs) during the busiest hour in a cell or across the entire radio network. It indicates how efficiently the uplink resources are being utilized to handle traffic demands.
Definition:
The Uplink Resource Block Utilizing Rate KPI is defined in Table below.
3. Uplink Preschedule Resource Block Occupied Rate.
This KPI measures the percentage of uplink Resource Blocks (RBs) that are allocated to UEs for pre-scheduling. It helps evaluate the impact of pre-scheduling on uplink RB usage. When pre-scheduling is enabled, if there are remaining uplink RBs in a cell, the eNodeB allocates these RBs to UEs that have not sent a bandwidth request, aiming to reduce uplink service delay.
The Uplink Preschedule Resource Block Occupied Rate KPI is defined in Table below.
4. LTE Average CPU Load.
This KPI indicates the CPU usage of the network elements (e.g., eNodeB) during busy hours. It helps in understanding the processing load and ensuring that the network hardware is not overburdened, which could impact performance.
Definition:
The Average CPU Load KPI is defined in Table below. It is calculated by averaging the CPU usage ratio over the measurement period.
5. Downlink Resource Block Utilizing Rate (NSA DC).
This KPI measures the utilization rate of downlink Resource Blocks (RBs) by Non-Standalone Dual Connectivity (NSA DC) User Equipments (UEs) during busy hours in a cell or on a radio network. It helps in understanding how effectively the downlink resources are being utilized by NSA DC UEs.
The Downlink Resource Block Utilizing Rate (NSA DC) KPI is defined in Table below.
6. Uplink Resource Block Utilizing Rate (NSA DC)
This KPI measures the utilization rate of uplink Resource Blocks (RBs) by NSA DC UEs during busy hours in a cell or on a radio network. It helps in evaluating the effectiveness of uplink resource usage by NSA DC UEs.
The Uplink Resource Block Utilizing Rate (NSA DC) KPI is defined in Table below.
These KPIs are essential for monitoring and optimizing the resource allocation and performance of NSA DC UEs in the network, ensuring efficient use of both downlink and uplink resources.
