    hello, if your using E******* you can use the following formula for speech IRAT success rate :


    100*(pmNoSuccessOutIratHoMulti + pmNoSuccessOutIratHoSpeech)/(pmNoAttOutIratHoMulti +pmNoAttOutIratHoSpeech)

    I think what you want to calculate is IRAT HO per user right ?
    dividing IRAT attempts to No. calls will not give you a proper view as the calls will be moved to another cells
    so it is better to divide IRAT HO attempts to Traffic in erlang

    cheers

    Hi,
    My query was w.r.t "IRAT attempt rate" which is different from IRAT HO success rate (HOSR).

    This is more for device issues. i.e which device is causing more HO attempt for the same call...
    it should be inline with : IRAT attempts / Total calls *100. Wanted a second opinion on this...
