    i don’t understand “rlcrp” and “bcch=0”.

    if it means that MS can’t setup a call in this cell but can only access it with handover, then either the cell is barred or the BCCH trx is suffering bad interference or hardware failures.

    Perhaps there are some other reasons, but what you could try to do already is to lock the first TRX and see the results.

    If that cell can carry HO traffic but no TCH traffic . i suggest you to chcek Cell ID on MSC it might not define on MSC side.
    If CI already defind on MSC.
    Pls confirm this dosen’t bar.

    Good lock

    go on site, perform a drive test trace
    can you select/reselect the cell ?
    what are the values of C1 & C2 ?
    when you set up a call what happens ?
    when you send SMS ?

    please list down the message flow (layer 3)

    what is the sdcch assignment failure rate ?
    sdcch drop rate ?
    tch normal assignment failure rate ?
    call drop rate ?
    tch duration average ?
    sdcch duration average ?

    thanks,

    Hi MSA..

    Check after deleting & recreating cell_ID from MSC End..
    There must be some configration problem at MSC end thats why it in only carrying handover traffic.
    So deleting & redefining Cell ID may resolve the Issue.

    from wat u’ve said this’s ericsson network. Go in OSS, run mgcep on mss, run rldep on bsc. Get the cgi n both cases & compare. They s’d be same.
