    Default Supported AMR Codec

    Dears,

    in GSM, we could define supported AMR codec from BSC/ Cell side
    just I'm wondering

    Do we have same option in UMTS to configure AMR Codec from RNC/Cell side
    if Yes, which parameter please !

    Dear justdream

    There is an option from RNC side : Setting AMRC Algorithm Parameters

    Setting the Adaptive Multi-Rate Control (AMRC) algorithm parameters of an RNC, such as downlink power measurement thresholds, uplink and downlink mode change waiting timer length.

    Parameters: UL Reporting Mode, DL Measurement Reporting Period, DL E1 Event Relative Threshold, DL E2 Event Relative Threshold, DL F1 Event Relative Threshold, DL F2 Event Relative Threshold, UL Mode Change Timer Length, DL Mode Change Waiting Timer Length, Max Mode of Narrowband AMRC for Golden Users, Max Mode of Narrowband AMRC for Silver Users, Max Mode of Narrowband AMRC for Copper Users.

    Dears,
    Please which counters show UMTS CS traffic based on Codec Set (12.2, 5.69, etc)

    Hi justdream,
    in Huawei m2000 look for under
    RNC:
    Measurement Related to AMR -->
    AMR service measurment<per RNC>

    cells:
    Measuremet related to radio bearer -> RB procedure measumernt per cell

    WBAMR voice : VS.RB.AMRWB.DL/UL.xx.xx
    AMR voice: VS.RB.AMR.DL/UL.x.xx

    regards,
    isha

    Hi,

    Thats right, but if you dont have config "code set" in the CN (its depend of the vendor) it doesnt work !! CN should be able to give the codec requested! . by the way, AMRC for HW it is a feature that sometimes its not included.

    BR,
