How do you compute the variance of the measured traffic? 10th July 2009 at 19:53 #57875 Reply pixGuest mean use time / time between request for ex: calls = 60s average in between = 2s 60/2 = 30 erlangs ok, that’s a weird computation 🙂 but it works if you want to know the variance, you need to know the duration of each call, or find a QoS indicator that measures the distribution of call duration. I believe you can find such data in the MSC/VLR, not in the BSS counters.
