    Default Feature improving CDR, CSSR, MOS and saving energy

    Hi Experts,
    We applied feature Enhanced BCCH Power Consumption Optimization vendor HW for 100 sites 2G HW and this is result:

    • KPI OSS: CDR improving ~30%, CSSR improving ~20%. (file attached)
    • Energy saving: 3 KWh/site/day.

    • KPI driving test:

    + MOS-2G improving 0.12 point from 3.69=>3.81.
    + CSSR-2G improving 100% from 97.37=>100%.
    + CDR-2G improving 61.81% from 2.7=>1.03%.
    + RxQual Sub improving 23.53% from 0.62=>0.47.
    + HO/Call improving 32% from 2.68=>1.81.

    • Feature description:

    The Enhanced BCCH Power Consumption Optimization feature reduces the transmit power of non-BCCH timeslots (timeslots 1 to 7) on the BCCH TRX. This feature provides the following functions:
    Function 1: reducing the transmit power of idle timeslots among timeslots 1 to 7 on the BCCH TRX
    Function 2: performing downlink power control on occupied timeslots among timeslots 1 to 7 on the BCCH TRX
