    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

    Installation 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 ofthe 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 ofthe 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 servicefunction 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 locate them and retest until

    the problems are solved and process terminates.

    Single Site Verification Task ofthe 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
