If you multiply BHCA x MHT = Traffic Volume (TV) in BH. And If you devide TV/Subs= Average Traffic Volume per One subscriber.
In Erlangs this is: TV/((Subs)*X)
X=60 – MHT in [min]
X=3600 – MHT in [sec]
This is in case you are looking for the average traffic per user in BH. For traffic calculations this value is needed. But if you need the average traffic per day, you must multiply TV in BH with a concentration factor. In the books the concentration of traffic in BH is about 15-20%. But in our network the concentration is less than 12%.
