    hi mstc,

    paging discard is probably due to congestion. Congestion will mostly occur:
    1- in the BSC itself
    2- on the Abis signalling link
    3- on the PCH (air interface)

    1- in the BSC itself
    reduce the number of LACs being handled by this BSC. Usually, 1 BSC = 1 or 2 LAC.

    2- on the Abis signalling link
    increase the signalling capacity: instead of using 4 signalling links (= 4 RSL) per abis TS, use only 2.

    3- on the PCH (air interface)
    increase the number of PCH blocks, e.g reduce the parameter AG_BLKS_RES to a lower value. If it was =4, put it to 3. But check your AGCH congestion, because what you are doing is giving more capacity to PCH by reducing the AGCH capacity.
    If it doesn’t work, then you have to reduce your number of cells per LAC.

    regards
