KPI´S UTRAN ERICSSON
1. OBJETO
Este documento describe los indicadores y las fórmulas asociadas necesarias, para evaluar la
calidad de la red radio Ericsson, propuestos por el suministrador y estudiados en el grupo de
trabajo de estadísticas.
Los indicadores propuestos cubren los servicios de voz, videotelefonía, datos y streaming.

3. KPI´S UTRAN ERICSSON

Call Completion
Se define como la probabilidad de soportar con éxito una conexión desde el acceso hasta la
desconexión normal por parte del usuario final.

Accesibilidad (RRC+RAB)
Se define como la probabilidad de establecer con éxito una conexión para el servicio deseado.

Capacidad de retención (1-CDR)
Se define como la probabilidad de que una conexión sea terminada adecuadamente (con éxito)
por el usuario final, una vez se haya garantizado su acceso a red.

Integridad
Se define como la probabilidad de que la conexión establecida se mantenga dentro de los
márgenes de calidad requerida, la cual es definida en términos de BLER objetivo.
A parte de estos indicadores habituales, se han añadido al documento los siguientes:

Cell Update
La tasa de éxito de actualizaciones de célula.

Indisponibilidad
La indisponibilidad a nivel de célula se puede medir en base a los tiempos en los que una célula se
encuentra deshabilitada y no bloqueada por el administrador del sistema, habitualmente en forma
de porcentaje a lo largo del día (24h)

3.1. Call Completion Success Rate (CCSR)
Se define como la probabilidad de soportar con éxito una conexión, desde el acceso hasta la
desconexión normal de la misma originada por el usuario final.
Es el resultado de multiplicar la tasa de éxito de establecimiento de la conexión por la
probabilidad de retención de la misma.
CCSR = CSSR ⋅ (1 − CDR )
Esta misma fórmula aplica a todos los tipos de servicio (RAB).
CDR: Call Drop Rate.
3.2. Accesibilidad
La Tasa de Llamadas Establecidas con Éxito (CSSR) se define como el producto de la tasa
de éxito de establecimiento de la conexión RRC y la de establecimiento del RAB.

After an RRC Connection Request message is received by
RNC, if not already known in the RNC, an internal
UE identity is assigned to the requesting UE. Then
RNC asks permission both from RNC Main Processor
(MP) load control and admission control functions.
Having received permission to continue, allocates a DL
channelization code and then starts to set up a connection
towards the RBS. Also the UE is requested to setup an
RRC connection with RRC Connection Setupmessage.
Once NBAP Radio Link Restore Indication message
and RRC Connection Setup Complete message have been
received by RNC, then the RRC connection is considered
to be successfully established. The counter is now
increased.

This counter is increased when the RRC message Cell Update

sending of Cell Update

Confirm message must be received from UE to step the counter.
The counter is increased for the cell where the Cell Update
Confirm message was received (in the new cell if cell has
changed). These cell update procedures can happen at cell
update in same cell (periodic update), cell update in new cell
(cell re-selection), cell update during channel switching and cell
update during RAB establishment. The cases when an AM
