Hi Lex,
reason: Number of error indications due to T200 expired on SDCCH(Num)

Also we get trace and we observe ; several times sdcch drop happens when location update happens, while signal level and quality is good. So we also increase resel hsty and even we delete 3g cell re-selection parameter.

There is only one kpi change while sdcch drop problem happens. Meanholding time increases due to comunication(t200)drops creates waiting time until period finishes.

Also there is no sdcch traffic type change.

Also problem not happens 9am-4pm period.
