    hello sazzy,

    next time, try to use these words in your post : “please”, “thank you”

    sdcch blocking rate = (sdcch requests – sdcch assignments) / sdcch requests

    sdcch drop rate = sdcch drops / sdcch assignment success (= sdcch seized)

    Owww, that’s for me then…

    It looks like a HW issue or a configuration issue. Check/reset/replace your TRXs,…

    Do you have similar issues on other cells ? After a reset, the problem is still here ?
    Did it appear suddenly ?
    Or was it here since the fist commisionning ?

    Dear Pix,
    From the commisioning day and we found that most of the sites either in lac boundary or stand alone.

    Thankx

    I think you should ask for ALU support. If the sites are newly deployed, you probably bought some support from ALU as well. So check with them.
    I suspect wrong configuration of the sites…

    hi,

    what is the terrain topology like ?
    reduce antenna height ?
    change azimuth ?
    change antenna (narrower beamwidth, les secondary lobes)

    if nothing works, you’ll have to decrease the tx power of the bts.

    regards
