Proposito End to End KPI Concept KPI- Availability KPI- Accessibility KPI-Dropped Call Rate KPI-Quality KPI-Handover Failure Recomendaciones


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


Availability X 0,20

Accessability X 0,20

DroppedCall Rate- X 0,35

Quality X 0,20

HandoverFailure Rate X 0,05

E2EKPI

Seria un KPI ponderado en donde cada KPI esmultiplicado con peso según su importancia en laFormula

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 enasignacion 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, anivel de TRX’s debe ser promediado por cell y el de BTS’s será elmismo por cell


AccessibilityCell = {[Successful Assignments]-{[Assignment Requests (SignalingChannel) (SDCCH)]+[Assignment Requests (Signaling Channel) (TCH)]-[Failed Assignments (Signaling Channel)]+[Assignment Requests (TCH AssignedRepeatedly over A Interface)]-[Failed Assignments (TCH Assigned Repeatedly over AInterface)]}} x{100%} / {[SDCCH Seizures for Speech Service]+[TCHF Seizures for SpeechService]+[TCHH Seizures for Speech Service]}

AccessibilityCell = {CA313-{A3100K + A3100A - A312S + CA310A-CA312A}}x {100%}/{A3039J + A301F + A301HH}

Esta formula expresan el rate desde que el MS inicia la llamadahasta el establecimiento de la misma (SDCCH, TCH, Etc.)


Dropped Call Rate = (CM33:Call Drops on Traffic Channel (None) /(M318:Successful Connections (TCHF) (Traffic Channel) (None) + M328:SuccessfulConnections (TCHH) (Traffic Channel) (None) ))-100

Esta formula expresan el rate de Drop de las llamadas establecidas


Quality% = (CS410B:Number of MRs on Downlink TCHF (Mean Receive Quality Rank 0) (None)+ CS410D:Number ofMRs on Downlink TCHH (Mean Receive Quality Rank 0) (None) + CS411B:Number of MRs on Downlink TCHF (Mean ReceiveQuality Rank 1) (None) + CS411D:Number of MRs on Downlink TCHH (Mean Receive Quality Rank 1) (None)+CS412B:Number of MRs on Downlink TCHF (Mean Receive Quality Rank 2) (None)+ CS412D:Number of MRs on DownlinkTCHH (Mean Receive Quality Rank 2) (None) +CS413B:Number of MRs on Downlink TCHF (Mean Receive Quality Rank 3)(None)+ CS413D:Number of MRs on Downlink TCHH (Mean Receive Quality Rank 3) (None)+ CS414B:Number of MRs onDownlink TCHF (Mean Receive Quality Rank 4) (None) CS414D:Number of MRs on Downlink TCHH (Mean Receive QualityRank 4) (None) / (CS410B:Number of MRs on Downlink TCHF (Mean Receive Quality Rank 0) (None)+ CS410D:Number ofMRs on Downlink TCHH (Mean Receive Quality Rank 0) (None) + CS411B:Number of MRs on Downlink TCHF (Mean ReceiveQuality Rank 1) (None) + CS411D:Number of MRs on Downlink TCHH (Mean Receive Quality Rank 1) (None)+CS412B:Number of MRs on Downlink TCHF (Mean Receive Quality Rank 2) (None)+ CS412D:Number of MRs on DownlinkTCHH (Mean Receive Quality Rank 2) (None) +CS413B:Number of MRs on Downlink TCHF (Mean Receive Quality Rank 3)(None)+ CS413D:Number of MRs on Downlink TCHH (Mean Receive Quality Rank 3) (None)+ CS414B:Number of MRs onDownlink TCHF (Mean Receive Quality Rank 4) (None) CS414D:Number of MRs on Downlink TCHH (Mean Receive QualityRank 4) (None)+ CS415B:Number of MRs on Downlink TCHF (Mean Receive Quality Rank 5) (None)+ CS415D:Number ofMRs on Downlink TCHH (Mean Receive Quality Rank 5) (None) CS416B:Number of MRs on Downlink TCHF (Mean ReceiveQuality Rank 6) (None) +CS416D:Number of MRs on Downlink TCHH (Mean Receive Quality Rank 6) (None)+CS417B:Number of MRs on Downlink TCHF (Mean Receive Quality Rank 7) (None)+ CS417D:Number of MRs on DownlinkTCHH (Mean Receive Quality Rank 7) (None) )

Esta formula expresan el porcentajes de muestra de calidad 1 hasta 4de canales Full y Half


Handover Failure % = {[Number of Successful Outgoing Internal Inter-CellHandovers] + [Successful Outgoing External Inter-Cell Handovers]} x {100%} /{[Number of Outgoing Internal Inter-Cell Handover Requests] + [Outgoing ExternalInter-Cell Handover Requests]}

Handover Failure % = (CH313 + CH333) x 100% / (CH310 + CH330)

Esta formula expresan el porcentajes de Handover exitosos
