    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

    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

    Verification in Idle Mode

    Frequency Check

    Check whether the frequency number of the cell to be measured isconsistent 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 consistentwith the planed one.

    CPICH_RSCP/CPICH_Ec/Io (Near Site) Test

    Check whether the CPICH RSCP and CPICH Ec/Io received by UE aregreater than the threshold

    Verification in connect Mode

    Originating and Terminating Connection Test of Voice Service

    Check whether the originating and terminating function of voice servicefunction 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 byhandset online service

    Solving Problems

    If on-site engineers find product function problems or parameter configurationproblems, the engineers must location them and retest until the problems aresolved and process terminates.

    Preparations

    Cell Status Confirmation

    Before checking site, you need to inquiry product support engineerswhether 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

    HSDPA Access Function Test

    To test HSDPA access function

    Antenna Diversity Check

    Check whether the antenna for receiving diversity signals is reverselyconnected

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

    Checking Antennas by Exchanging Feeders
