    How do you know that this is because of protocol issues? if so, please post a part of the trace messages containing failure, so that we can directly identify the reason….

    have you verified RF part? there could be reasons such as Bad BCCH or BSIC..etc

    Thanks

    Hi,
    In NSN system, I found high SDCCH Drop for entire site.
    When I looked for the subcounters
    I found,
    1.SDCCH drop due to radio interface failure
    2. SDCCH drop due to Radio interface message failure
    and
    3. SDCCH drop due to Assignment fail
    are high
    can any one tell me what to do for each of the case?
    what are the causes to increase the counters value ?

    regards//
