    possible causes of GSM sleeping cell

    Dear experts,

    I am handling one issue reported by customer mention about GSM sleeping cell. The radios , signaling link and all other hardware at site is working fine. There was no abnormal alarm from cell level, BTS level and also BSC level. The problem was recovered after resetting site.

    The customer wants to know the root cause but at this moment i do not have any clue from available logs. I would appreciated your support to list all possible causes.

    Thanks in advance.

    It can be due to hardware.If power saving parameter is also activated, in some cases, we can have this issue.

    Maybe check also the "ping" from SGSN. The SGSN should be "pinging" the MS in the cell in order to force the cell to be continuously "GPRS awake". If that feature has been disabled it can happen that sleeping cells increase.
