Basado en las recomendaciones de Marcos Ridolfi elaborar un KPI EndTo End utilizados en
otras que englobe todas las posibles puntos de Fallas de una Llamada tomando en cuenta
los KPI comunes en combinación de otros indicadores donde se puedan monitorear todos
los elementos (TRX’s , BTS, ABIS’s , Circuitos , Etc.)

Seria un KPI ponderado en donde cada KPI es
multiplicado con peso según su importancia en la
Formula
E2EKPI = 99.5(0.20) + 99(0.20) +
98.5(0.35) + 98(0.20) + 96(.05)

• Availability - Recursos disponibles en servicio a nivel de TRX’s ,
BTS’s.
• Accessability - El performance de la celda expresado en
asignacion de recursos (TCH’s y SDCCH’s)
• Dropped Call Rate - El rate de Drop de la Celda
• Quality - La calidad de la red medido en la interfaz de aire
(Downlink and Uplink).
• Handover Failure Rate - la eficiencia de traspaso de llamadas en
la red.

AvailabilityTrx = (({3600}-[R473:TRX Out-of-Service Duration])/
{3600})*{100}
AvailabilityBTS = {100}-(([R273:BTS Out-of-Service Duration]/
[CR273:BTS in-service duration])*{100})
Estas formulas expresan la disponibilidad a nivel de TRX’s y BTS’s, a
nivel de TRX’s debe ser promediado por cell y el de BTS’s será el
mismo por cell
