Reply To: AMR,how to calculate erlangs



22.2 erlangs is higher than 21.9 erlangs, so your cell is reaching its full capacity already. But it is true that it shouldn’t reach 65% congestion… Have you tried to increase the TCH queue timer ? Have you check all TS are used in HR ? When setting up a call in this cell, it will always be in HR or will it be FR until a certain traffic load, and then HR ?
