Radio Network Unavailability Rate -- LTE

Radio Network Unavailability Rate

Description

The Radio Network Unavailability Rate KPI indicates the percentage of time when cells in a radio network are unavailable. This KPI is used to evaluate the deterioration of network performance caused by unavailable cells on the radio network during busy hours.

Definition

The Radio Network Unavailability Rate KPI is defined in Table 1. This KPI is calculated based on the length of time all cell services are unavailable on the radio network.

Table 1 Radio Network Unavailability Rate

Name	Radio Network Unavailability Rate
Object	Radio network
Formula	RAN_Unavail_Rate = (ΣCellUnavailTime/(TheTotalNumberOfCellsInCluster x {SP} x 60)) x 100% NOTE: "SP" indicates the reporting period for counters in minutes.
Associated Counters	Radio Network Unavailability Rate =((L.Cell.Unavail.Dur.Sys + L.Cell.Unavail.Dur.Manual)/(Number of cells x {SP} x 60)) x 100% "SP" indicates the reporting period for counters in minutes.
