WCDMA Initial Tuning Technical Guideline

1 Introduction

1.1 General

Initial Tuning is an integral part of Radio Network Design Process as shown in Figure 1. The deliverables of the initial tuning are documented in initial tuning reports (analysis report and verification report). These reports are used as input to the acceptance sub-process. For every sub-process shown in Figure 1, there are relevant technical guidelines, templates and checklists for the engineer’s reference when delivering the service. Hence, the purpose of this document is to give guidance and information on how to perform an Initial Tuning service for a WCDMA network. The aim of this document is to create a common understanding of the procedures involved for delivering an Initial Tuning project.

1.1 Scope

The scope of this document is:

· To explain the main steps involved in delivering a WCDMA Radio Network Initial Tuning service.

· To give advice on tools and support used for performing the initial tuning service.

1.2 Definition of Initial Tuning Service

The purpose of Initial Tuning is to ensure the radio network works well after the network has been built or in case of an expansion. This service verifies that the radio network design and the corresponding network data have been implemented correctly, that the implemented design is consistent with the proposed design. The initial tuning is performed under the condition where the network is unloaded or with limited load (e.g. with friendly user traffic such as operator/Ericsson test users). The objective of the service is accomplished when the network is able to deliver network quality which a commercial network launch demands.
