    Dear all,
    Dear Pix!
    We are about to activate SDCCH HO in our network, but except EN_SDCCH_HO and SDCCH_COUNTER I can’t find in OMC-R any other parameters related to this feature. I think its mechanism must be similar to TCH HO, but by which thresholds and parameters is it regulated? Which cause/causes exist for SDCCH HO?
    It’s simple question but I can’t find the answer through our docs
    Thanks a lot for help

    Hi,

    Same causes than TCH HO, using same parameters.

    Basically, all standard causes are available (quality, level, distance, pbgt). I usually don’t recommend to activate it, but you can give it a try.

    Don’t forget that the HO algorithms can be checked only when the averaging windows are filled with values.

    Ex: A LEV HO = 4, you need at least 4 SACCH measurements before the HO “bad level” Detection can occur. If the SDCCH phase last 3 seconds, for the 2 first seconds, HO LEVEL cannot be detected.

    Once more many thanks, Pix!
    Everything’s clear 🙂

    …and soon we’ll have practical experience 🙂
