    WCDMA Optimization Flow Single Site Verification

  • Page13Copyright 2006 Huawei Technologies Co., Ltd. All rights reserved.

    Single Site Verification Purpose:

    The single site verification test is a part of the WCDMA networkoptimization to ensure that the basic functions of the cell are normal, such as call access, call quality, handover and so on.

    Single site verification involves the following aspects: Parameter setting check in idle mode Services call (AMR/VP/PS) function check in connected mode HSDPA function check CPICH RSCP & Ec/Io Installing problems check

    Single Site Verification Single site verification includes :

    preparations before test

    single site test

    solving problems

    The single site verification is completed by: On-site engineers

    RNO engineers

  • Page15Copyright 2006 Huawei Technologies Co., Ltd. All rights reserved.

    Single Site Verification - Task of the on-site engineers Preparations Site Status Check

    For each cell to be measured, check Status by LMT or M2000 Status

    Configuration Data Collection and Check check whether the data configured is consistent with the planned data

    Testing Point Selection Test UE Setup

    Set the handset to testing mode before test

    Other Preparations

    Application key

    Single Site Verification - Task of the on-site engineers Verification in Idle Mode Frequency Check

    Check whether the frequency number of the cell to be measured is consistent with the planned data

    Scramble Check Check whether the scramble configuration is consistent with the planned

    configuration LAC/RAC Check

    Check whether the LAC/RAC of the cell to be measured is consistent with the planed one.

    CPICH_RSCP/CPICH_Ec/Io (Near Site) Test Check whether the CPICH RSCP and CPICH Ec/Io received by UE are greater

    than the threshold

    Single Site Verification - Task of the on-site engineers Verification in connect Mode Originating and Terminating Connection Test of Voice Service

    Check whether the originating and terminating function of voice service function normally by call quality test

    Originating and Terminating Connection Test of VP Service Check whether the originating and terminating function of VP service function

    normally by call quality test Connection Test of PS Services

    Check whether the originating function of PS services are normal by handset online service

    Solving Problems If on-site engineers find product function problems or parameter configuration

    problems, the engineers must location them and retest until the problems are solved and process terminates.

    Single Site Verification Task of the RNO engineers Preparations

    Cell Status Confirmation

    Before checking site, you need to inquiry product support engineers whether the cell is in normal status

    Testing Route Selection Before test, you must select a proper testing route according to

    site distribution and local environment

    Precautions

    Single Site Verification Task of the RNO engineers Coverage DT Check

    Check whether CPICH RSCP and CPICH Ec/Io received by scanner is normal

    Abnormal power amplifier

    Abnormal connection of antenna-feeder

    Inconsistency of antenna tile/direction angle from planned one

    Blocking by buildings

  • Page20Copyright 2006 Huawei Technologies Co., Ltd. All rights reserved.

    Single Site Verification Task of the RNO engineers HSDPA Access Function Test

    To test HSDPA access function

    Check whether the antenna for receiving diversity signals is reversely connected

    Fixed Maximum Transmit Power of UE, measure the RTWP of the cells

    Checking Antennas by Exchanging Feeders

  • Page21Copyright 2006 Huawei Technologies Co., Ltd. All rights reserved.

    Single Site Verification Task of the RNO engineers

    Antenna Diversity Check The method for UE to transmit signals at the fixed maximum

    power is a recommended method of test and operation

    Solving Problems If RNO engineers find problems about product function, RNO

    engineers must ask product support engineers to solve problems

    Single Site Verification Summarization:

    In single site verification stage, engineers check whether equipment functions normally

    Single site verification is a basis for the following RF optimization and service optimization

    If all verifications about function are accepted, the single site verification is completed

    After single site verification, optimization comes to RF optimization

    RF Optimization - Overview Once all the sites are installed and verification is complete, RF

    optimization starts.

    During the RF optimization stage, you will optimize radio frequency (RF) signals , so that the distribution of radio signals is normal in next service -- parameters optimization stage

    RF optimization includes the following aspects: Coverage optimization

    Pilot pollution optimization

    Handover optimization
