    Can anyone inform how much traffic one LAC can handle by one BSC.

    It depends on the BHCA of the BSC

    The main constraint at BSC is probably the Paging processing capacity : if the LAC is too big, there could be too many pagings to process for the BSC.

    Don’t forget to cumulate the effect of all LACs in the BSC. For example, 4 LACs :
    LAC 1: handled by BSC A
    LAC 2: handled by BSC A and BSC B
    LAC 3: handled by BSC A
    LAC 4: handled by BSC B

    The total pagings in BSC A = pagings in LAC 1 + 2 + 3
    Total pagings in BSC B = LAC 2 + 4

    Even if BSC A only hosts 1 cell in LAC 2, it will have to process the full amount of pagings of LAC 2.

    Best Regards,

    you have to check how many cells are in your LAC, after that you have to get the traffic for those cells. is important calculate the BHCA for every LAC, and after you have to see the way to unload the signaling traffic for every cells because is in the SDCCH and the configutation parameters of BSC where you have the problem.
