Service
Integrity KPIs
Cell Downlink Average Throughput
This KPI evaluates the cell downlink
average throughput when there are data transferring at downlink. It reflects
the cell capacity.
Related Counter - DL Traffic Volume
Description:
The counters measure the total
traffic volume of transmitted PDCP SDUs for each service with a specific QCI
ranging from 1 to 9 in a cell.
Measurement Point
The size of the payloads in the
transmitted PDCP SDUs of each service with a specific QCI is sampled in a cell.
At the end of a measurement period, the sum of these sampling results is used
as the value of the corresponding counter.
- The downlink traffic volume KPIs consist of nine sub-KPIs mapped to nine QCIs. This group of KPIs can be used to evaluate the DL traffic volume for each QCI in a cell, which is measured at the PDCP layer excluding the RLC header and RLC retransmission.
- Downlink Traffic Volume for PDCP SDUs
Description:
The counters measure the transmit
duration of downlink PDCP SDUs for services with a specific QCI ranging from 1
to 9 in a cell.
Measurement Point
The transmit duration of downlink PDCP
SDUs for each service with a specific QCI ranging from 1 to 9 in a cell is
sampled per millisecond. If there is downlink data transmission within this
millisecond, the sampling result of the corresponding counter is 1. At the end
of a measurement period, the sum of these sampling results is used as the value
of the corresponding counter.

Cell Uplink Average Throughput
Related Counter - UL Traffic Volume
Description:
The counters measure the total traffic
volume of received PDCP SDUs for each service with a specific QCI ranging from
1 to 9 in a cell.
Measurement Point
The size of the payloads in the
received PDCP SDUs of each service with a specific QCI is sampled in a cell. At
the end of a measurement period, the sum of these sampling results is used as
the value of the corresponding counter.
- Uplink Traffic Volume for PDCP SDUs
Related Counter – UL Receiving Time
Description:
The counters measure the receive duration
of uplink PDCP SDUs for services with a specific QCI ranging from 1 to 9 in a
cell.
Measurement Point
The receive duration of uplink PDCP SDUs
for each service with a specific QCI ranging from 1 to 9 in a cell is sampled
per millisecond. If there is uplink data receiving within this millisecond, the
sampling result of the corresponding counter is 1. At the end of a measurement
period, the sum of these sampling results is used as the value of the
corresponding counter.
