Chapter 1 Introduction
The purpose of this document is to specify the RAN KPI definition as well as counters
used to calculate the KPI.
The original KPI definition comes from the experiences of the commercial network
management and radio network optimization. And the KPI definition shall be updated
according to the requirement from customers.

Chapter 2 KPI definition template
The template used to describer the KPI is listed as follows:
I. KPI name (Clause header)
This is a descriptive name of the KPI that is specified.
II. Description
This sub clause contains an explanation of the KPI.
III. Measurement Scope
This sub clause specifies the KPI work scope. If the scope is ‘RNC’, it means that the
KPI value shows the performance on the RAN and the related counters can be gotten
from RNC statistic directly. If the scope is ‘Cell’, it means that KPI value only shows the
performance in a cell and the involved counters can be gotten from cell statistic.
IV. Formula
This sub clause contains a formula used to calculate the KPI. Generally the formula
consists of several counters which shall be explained in other sub clause.
V. Associated Counters
This sub clause contains counters that used in the formula. It also contains the
description of the counters. Annex A provides the counter list.

Chapter 5 Accessibility KPIs
5.1 IU Paging Success Ratio
5.1.1 Description
This KPI can be used to evaluate the success response to the paging from the core
network in one RNC. However the lower paging success ratio does not always mean
the lower paging response, because it may be caused by the unnecessary paging
messages from the core network. So it‘s important to analyze the terminated radio
access success ratio and the core network’s paging strategy for further confirmation.

5.2 Radio Access Success Ratio
5.2.1 Description
A complete call setup procedure contains the RRC, RAB, and Direct Transfer
procedure. Generally only the RRC and the RAB procedure can be observed from
RAN and it is usually assumed that there is no error occurred when RAN handling the
direct transfer messages. That is the authentication procedure will be considered to be
performed successfully.

9.7.1 Description
This grouped KPI can be used to evaluate the consumption of IUB bandwidth in one
NodeB from uplink and downlink on busy hour. However the consumption of
interactive and background service can’t keep the full rate all time on the configured
IUB bandwidth. For further study, the utilizing rate can be devided into two classes,
configuration consumption and real time consumption. So there are four KPIs listed in
the following definition.
