3GPP Cell Availability KPI in LTE
LTE Cell availability is simply the amount of time the cell is available to users over the measurement time.
A cell is considered available if it can provide E-RAB service to the UE.
The time the cell is available is typically derived by taking the OSS measurement period and subtracting the amount of time the cell was unavailable.
In addition, the amount of time the cell is unavailable should include both automatic outages (e.g., alarm triggered) and manual outages such as maintenance or software/ hardware upgrades.
