    Dear All

    can anybody explain to me how to calculate the traffic loss ( due to the congestion)

    Regards

    a tch congestion of 2% means that 2% of your TCH assignment requests are rejected. Multiply this amount by the average duration of a call, and that gives you the traffic loss.

    Hi Pix

    for example I have 80% Congestion in my cell then i want to know the traffic offered so i should multiplay it by the average duration of call ?

    hi

    let’s say 1000 TCH request

    80% of the 1000 requests are rejected –> 800 requests are rejected, in one hour.

    800 TCH requests could lead to 800 * 30s of TCH occupancy, if you assume that an average call duration is 30seconds, AND if you assume there is 1 TCH request for 1 call request.

    For such high congestion, you should assume that there is at least 2 requests for 1 call request (call is re-attempted by subscriber)

    So in your situation : 400 * 30s = 12,000 s of occupancy is rejected, so it’s about “12,000/3600” erlang that are “lost”.
