    100*(sum(rach_attempt- rach_failure)/sum(rach_attempt))*(1-sum(sdcch_drops)/sum(sdcch_seizures))*(1-sum(sdcch_block)/sum(sdcch_attempt))*(sum(tch_seizures)/sum(tch_attempt)) = CSSR

    Dear thanks but i have one comment?
    Why you are not taking directly RTCH assignmnet failure rate instead of 1-RTCH assignmnet fail due to the reason you mentioned.
