KPI Introduction
KPIs are high level metrics, which gives general information on system resource usage,
traffic, end user experience and network performance.
KPIs are usually used as a first indication whether the system is highly loaded, or there
are any potential performance issues, through which the operator can use the underlying
raw counters or tracing tool for detailed analysis.

2.1 Paging Congestion Rate
Description
The KPI shows the probability of dropping a paging record since the waiting queue is
overloaded.
Measurement Method
Counters at eNodeB side are designed to enable the corresponding measurement:
● Number of Paging Request From MME
● Number of Paging Loss From MME

2.7 E-RAB Block Rate
Description
The KPI shows probability for an end-user to be rejected with an E-RAB at request due to
eNodeB admission control, within the Initial Context Setup procedure or the E-RAB Setup
procedure.
Measurement Method
Counters at eNodeB side are designed to enable the corresponding measurement, which
are split into sub-counters per QCI:
● Number of failed initial E-RAB establishments due to admission control failure per QCI
● Number of failed added E-RAB establishments due to admission control failure per QCI
● Number of successful initial E-RAB establishments per QCI
● Number of successful added E-RAB establishments per QCI
● Number of failed initial E-RAB establishments per QCI and per failure cause (admission
control failure, Uu Interface Failure, Parameter Error, other reason)
● Number of failed added E-RAB establishments Per QCI and per failure cause (admission
control failure, Uu Interface Failure, Handover Trigger, Parameter Error, other reason)

3.1 RRC Drop Rate
Description
The KPI shows probability for an end-user to lose the RRC connection.
Measurement Method
Counters at eNodeB side are designed to enable the corresponding measurement, which
are split into sub-counters per release cause:
● Number of abnormal RRC connection release per release cause(These counters are
provided on per cell basis granularity in a non-overlapping 15 minute periodicity, at the
beginning of which they are re-initialized with the default value.)
● Number of successfully established RRC connection, including initial RRC connection
establishment and handover in/out RRC connection(These counters are provided on
per cell basis granularity in a non-overlapping 15 minute periodicity. This measurement
is obtained by accumulating the number of established RRC connections during the
measurement period.)

4.1 Intra-eNB Handover(Cell)
Description
The KPI shows probability for an end-user to succeed in a intra-eNB handover procedure,
on the target cell basis.
Measurement Method
Counters at eNodeB side are designed to enable the corresponding measurement, which
are split into sub-counters per failure cause:
● Number of successful intra-eNB intra-freq incoming handover preparations per cell
● Number of failed intra-eNB intra-freq incoming handover preparations per cell per failure
cause
● Number of successful intra-eNB intra-freq outgoing handover preparations per cell
● Number of failed intra-eNB intra-freq outgoing handover preparations per cell per failure
cause
● Number of successful intra-eNB intra-freq incoming handover executions per cell
● Number of failed intra-eNB intra-freq incoming handover executions per cell per failure
cause
● Number of successful intra-eNB intra-freq outgoing handover executions per cell
● Number of failed intra-eNB intra-freq outgoing handover executions per cell per failure
● Number of successful intra-eNB inter-freq incoming handover preparations per cell

4.2 Handover Via X2(Cell)
Description
The KPI shows probability for an end-user to succeed in a inter-eNB via X2 handover
procedure, on the target cell basis.
Measurement Method
Counters at eNodeB side are designed to enable the corresponding measurement, which
are split into sub-counters per failure cause:
● Number of successful inter-eNB via X2 intra-freq incoming handover preparations per
cell
● Number of failed inter-eNB via X2 intra-freq incoming handover preparations per cell per
failure cause
● Number of successful inter-eNB via X2 intra-freq outgoing handover preparations per
cell
● Number of failed inter-eNB via X2 intra-freq outgoing handover preparations per cell per
failure cause
● Number of successful inter-eNB via X2 intra-freq outgoing handover executions per cell
● Number of failed inter-eNB via X2 intra-freq outgoing handover executions per cell per
failure cause

5.3 PDCP SDU Loss Rate
Description
The KPI shows the fraction of IP packets (PDCP SDUs) which are lost (not successfully
received).
Measurement Method
Counters at eNodeB side are designed to enable the corresponding measurement:
● Number of Lost UL PDCP SDUs Per QCI. (A lost PDCP SDUs is the one not successfully
received by the eNodeB on the uplink after an attempt has been made to transmit part or all
of the packet on the air interface but the entire packet has not been successfully received.)
● Number of UL PDCP SDUs Per QCI

● Number of Lost DL PDCP SDUs Per QCI. (A lost PDCP SDU is the one whose context
is removed from the eNodeB after an attempt has been made to transmit part or all of the
packet on the air interface but the entire packet has not been successfully transmitted.)
