INTRODUCTION 1.1 Purpose This document describes the processes for Radio Access Network (RAN) optimization of the AMX LATAM WCDMA based third generation radio access network. The focus of this document is on the Radio Frequency (RF) optimization and acceptance criteria. 1.2 Overview The figure below shows the overview of acceptance requirement for the AMX LATAM project. Figure 1 : AMX Acceptance Overview – NSN proposed version Site implementation acceptance is carried out by the implementation team after the site has been commissioned and put on air. Once site implementation acceptance has been granted and the cluster is deemed fit for optimization, RF cluster acceptance will begin. Here stationary and drive testing will be carried out. Once the KPI’s are achieved for all clusters, the RF project acceptance could begin. At this phase all tests carried out at the cluster acceptance will be done again at project level. The main diference here is, besides the amout of points of interstes of the stationary tests, the coverage test. Coverage verification at project level is carried out under 50% load. The other tests do not need this additional loading. After that Provisional Acceptance (PAC) can be granted. For the Final Acceptance (FAC) many key performance indicators need to be above the customer target during a certain stability period. The figure below shows the relationship between all acceptance stages.

RF CLUSTER ACCEPTANCE The figure below gives an overview of the RF Cluster Acceptance process. Figure 3 : RF Cluster Acceptance Process Overview * Only for clusters which contain 3G/2G borders sites The RF cluster acceptance process can be grouped into 3 main sections which are the preparation phase, optimization phase and the acceptance phase. 2.1 Preparation Phase This phase is triggered once the rollout phase is approaching its end. The objective of this phase is to prepare all the pre-requisites for the optimization phase. This can be broken down as below: V Compilation of planning data V Site Clustering Perform Mobile Testing Data Processing, Analysis & Report KPIsAchieved Submit Report to AMX Network Optimization & Change Request RF Cluster Acceptance Project Acceptance Phase Y N Network Planning Rollout Phase Perform Stationary Testing Preparation Stage for Cluster Acceptance Testing Perform IRAT Testing* Preparation Phase Optimization Phase Acceptance Phase Perform RAU Testing Perform Mobile Testing Data Processing, Analysis & Report KPIsAchieved Submit Report to AMX Network Optimization & Change Request RF Cluster Acceptance Project Acceptance Phase Y N Network Planning Rollout Phase Perform Stationary Testing Preparation Stage for Cluster Acceptance Testing Perform IRAT Testing* Preparation Phase Optimization Phase Acceptance Phase Perform RAU Testing GUIDELINES Version Status RF Optimization Guideline for AMX 3G Rollout 1 Consulting and System Integrations August, 27 th 2007 Revised by: Danilo Cabral Raj Sandhu, Allan Bispo and Daniel Platero V Drive Routes & Site Selection for IRAT and Stationary Test V Field Measurement Tools V Post-processing Tools V Parameter Consistency Check V Alarm Monitoring V PrxNoise Check V Cell Availability 2.1.1 Compilation of planning data It is essential that all the planning data be collected and saved in an organized manner in order to be useful during the optimization phase. The required information from planning stage is: V Technical Site Survey Report (TSSR) including panoramic pictures V As-built Site Drawing V Complete Site Database including Site_ID, Cell_ID, RNC_ID, BTS_ID, LAC, RAC, URA, SAC, Antenna Type, Antenna Height, Azimuth, Tilt (Mechanical and Electrical), Scrambling Code, ATM layer parameters, Iu parameters, IP settings etc V Coverage plots for Loaded and Unloaded cases V Service Area plots for the services that require optimization 2.1.2 Site Clustering The clusters shall be defined by Nokia Siemens Networks and documented. Following criteria shall be used in defining the cluster: 1. Each cluster shall comprise a contiguous network area of approximately 10 to 15 sites. 2. Cluster shall not be defined across RNC boundary. 2.1.3 Drive Routes and Site Selection for Stationary Test, IRAT and RAU The drive routes for cluster acceptance will be mutually agreed by America Movil LatAm and NOKIA SIEMENS NETWORKS. Drive Routes must cover all main avenues and large streets within in the cluster. Main avenues should be driven in both directions as possible. The drive routes shall be selected such that the drive route can be completed, regarding all tests scenarios mutually agreed with the customer, in one (1) day. IRAT and stationary tests will demand one (1) additional day. Target sites for Stationary testing, IRAT and RAU will be mutually agreed by America Movil LatAm and NOKIA SIEMENS NETWORKS. The IRAT sites will also be known as 3G/2G Border Sites. Ensure the following has been carried out V The stationary test locations have been mutually agreed by America Movil LatAm and NOKIA SIEMENS NETWORKS. This should not be more then 20% of the total sites in the cluster and should be carried out in all sectors of the selected sites.
