HUAWEI RAN KPI for Performance Management

Key words: RAN, KPI, Performance Management

Abstract: This document is a contribution to the RAN KPIs on RNC performance

statistics. The document proposes a list of UMTS network level KPIs that should be

measured and used to evaluate radio network performance from coverage, accessibility,

retainablity, mobility, quality and traffic.

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.

2 KPI definition template

The template used to describer the KPI is listed as follows: KPI name (Clause header)

This is a descriptive name of the KPI that is specified. Description

This sub clause contains an explanation of the KPI. 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.

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.

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.

Class

This property is labeled at the KPI name. Class A means the KPI is a basic one, and must be monitored in M2000. Class B means the KPI is a additional one, it is useful for optimization, and is a optional KPI monitored in M2000.

3 KPI classification

The KPI can be divided into following classes, and the counters related to the KPI shall be well defined in the PM system of RNC.

5.1.1 Description

(11)

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 Class A - 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.

This KPI can be used to evaluate the radio access success ratio in one RNC and the access

failures caused by the SCCP congestion are not considered in this call setup procedure.
