1 Introduction

1.1 Purpose

The scope of work delivered by Huawei RNO Team on the Network Performance

Improvement and Roll-out Project is a successful achievement. The activities that are implemented

during the course of this program are listed below

New RNC Planning

New LAC and RAC planning

Scramble code Planning for the New Sites

Neighbor Optimization Activity

Antenna adjustment

RNC Parameter Settings based on HLD

Correction of Inconsistency Data in the network

Worse Cell Optimization

Congestion Issues process

Alarm monitoring and troubleshooting

New build Drive Test

Swapped feeder Rectification

The cluster’s new sites Roll-out and optimization started from (xx) till (xx), all activities are

properly implemented during the period.

The Target of the Key Performance Indicator (KPI) is to achieve the threshold listed in chapter

4.

Huawei is intended to provide to Ethio Telecom a comprehensive view of the subject cluster

performance and status within the network to which it has been integrated. This document forms the

formal Final Cluster Acceptance deliverable with-respect-to the subject Cluster.

1.2 Network Optimization Procedure

Radio network optimization aims to improve network performance and maximize the benefit of

the existing network resources through parameter collection, data analysis, parameter adjustment,

and necessary technical means after site integrated and expansion.

Single site verification

To verify the functionality of sites, for example site installation, basic functions of the cell.

SSV were done from the first cluster site on air

Cluster RF optimization

To control interference & pilot pollution, and optimize coverage & 3G neighbor lists. The

cluster optimization started from July 2014 and finished by the end of August.

Services test & Para. Optimization, Trouble shooting

The parameter optimization and troubleshooting were done along all the project phase. During

the project some key issues which effect 3G network quality were solved. For example, multiple

carrier cell high call drop issue, PS 3G to 2G handover time too much issue, PS download speed not

stable issue and so on.

CDR and HSUPA CDR.

iii. Service Integrity: R99 PS FTP Downlink Throughput, HSDPA FTP Downlink

Throughput, and HSUPA FTP Uplink Throughput.

iv. Mobility : SHO Success rate, inter-Rat HO Success rate

The test tool:

Software: Nemo, Actix.

CS handy: U8860/U2800

HSDPA/HSUPA handy: E372

R99 handy: U2800

Coverage: Scanner

The KPIs selected have taken into account the above mentioned factors in order to capture the
