    4.2.2 SSV Test
    A.DT route and CQT point choose
     The route must cover all the sector
     CQT point must below all the sector and the coverage should be much stronger than other cells
    Sector.1





    Sector.3 Sector.2 Mark:
    mean CQT point
    Green circle is test route

    B.Site location check
    When find the site should check the plan location (Longitude/ Latitude) to the actual address, Longitude/ Latitude should correct to the actual address and record the original and new data in SSV report. Location information can obtain from GPS.
    C.Frequency check
    Test and check the actual frequency and compare with the plan data, record in SSV report.
    D.PSC Check
    Test and check the actual PSC of every cell and compare with the plan data, record in SSV report.
    E.LAC/RAC check
    Test and check the actual LAC&RAC and compare with the plan data, record in SSV report.
    F.Service function check(VC/VP/PS)
     Voice/Video dial both in Original call and Terminal call, check Accessibility / Retainability and Mobility function.
     PS attach/detach, PDP activation
    The test need cover all the cells.
    G.HSPA function check
    Test and confirm HSDPA and HSUPA is working normally.
    H.Coverage test
    Test around the site and cover all the sectors, to check PA function/ Antenna installing right / site block situation / coverage of every sector and so on.
    And best to do nearby test which should cover all the sectors and best not far than 100m to the site, the coverage should RSCP >-75dBm , CPICH Ec/Io > -8dB, otherwise need check the reason.
    I.Antenna swap check
    Antenna swap always mean sector coverage is opposite as plan data, for example as below sample:
    Sector swap coverage situation (sector.2 and sector.3 swap):

    Audit MML command
    1) RET check
    DSP RETSUBUNIT: ;

    2) Configuration check
    LST UCELL:LSTTYPE=ByCellName,CELLNAME="xxxx";


    3) SCCPCH CFG check (IBHRNC1 and IBHRNC5 must add second SCCPCH channel)
    One SCCPCH scene: SCCPCH ID 8

    Double SCCPCH scene: SCCPCH ID 8&9

    4) Feature check
    DSP UCELLCHK:CHECKSCOPE=CELLID,CELLID=xxxxxx;

    5) Neighbor check
    Intra neighbor
    LST UINTRAFREQNCELL:CELLID=xxxxx;
    Inter-freq neighbor
    LST UINTERFREQNCELL:CELLID=xxxxx;
    Inter-RAT neighbor
    LST U2GNCELL:CELLID=xxxxx;
