    Single Site Verification

    Purpose:

    The single site verification test is a part of the WCDMA network

    optimization 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 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 VerificationTask 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

    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 complete
