    Process Implementation New site

    Process for PLO

    Process Implementation Upgrade

    In process upgrading TRX, there isnt used Lock Value, after Implementation, check alarm, if clear, can beanouncement that site is on Air

    Lock Value

    For Site RFI, The Measurement for lock value min 3 hourly,

    Denses Urban, Urban, Sub Urban : 3%

  • 7/14/2019 PLO_2G_

    Measurement

    KPI measurements statistics are measured 24 hours aggregation usingdata from OSS system. Method and scope as follows:

    i. For new sites : using three(3) consecutive days measurement

    ii. For work description swap Network Element, Relocation

    Network Element, and Relocation Expansion NE, all KPI

    parameter will be monitored for 3 working days before and 3working days after.iii. For upgrading with additional sector/antenna

    iv. For upgrading without additional antenna.

    Based on Tinem 3, For Newsite we have Monitoring 6 KPI :

    Voice :

    1. SDSR (SDCCH Success Rate %)

    2. HOSR (Hand Over Success Rate %)

    3. TCHDR (TCH Drop Rate %)

    Data:1. TBFDLR (TBF Down-link Establishment Success Rate %)

    2. TBFULR (TBF uplink Establishment Success Rate %)

    3. TBFSR (TBF Success Rate %)

    Additional Monitoring :

    1. Traffic & TCHB

    2. Share Traffic & KPI Surronding fist layer

    Drive Test:

    1. CSSR

    2. Dropped Calls

    3. HOSR

    4. RX Qual 0-5

    5. SQI-18

    6. Idle Rx Level > -90 dBm

    7. Attach Success Ratio

    8. PDP Context Succes Ratio

    9. GPRS throughput

    ANALYSIS & RECOMEDATION For SDSR MEGAMENDUNGMG1

    OnAir

    Why ??

    SDSR GDGMEGAMENDNGMD1

    Analysis :

    Based on TQMALL SDSR of siteMEGAMENDUNGMG1 decrease

    Caused ABIS CAll high (20-21May). But from 22 May untilnow the performance SDSR ofsite MEGAMENDUNGMG1 isgood.

    Recommendation: after 21 MayThe performance SDSR is goodso we dont need give to

    recommendation.
